Suhasman, Suhasman, Detti Yunianti, Sahriyanti Saad, and Baharuddin Baharuddin. "Characteristics of Binderless Particleboard Made of Three Species of Sulawesi Bamboos." Wood Research Journal 4, no. 2 (August 31, 2017): 68–71. http://dx.doi.org/10.51850/wrj.2013.4.2.68-71.
Abstract:
Binderless particleboards (BP) were produced from three different species of Sulawesi bamboos. Parring bamboo (Gigantochloa ater) was extracted from Tanralili Maros while betung bamboo (Dendrocalamus asper) and tallang bamboo (Schizostacyum barcahycladum) were extracted from Batu Papan Makale Tana Toraja. The bark and nodes were removed, followed by cutting into chips; air drying, and finally converting into fine particles. The particles were oxidized using hydrogen peroxide 15% based on oven dry particle weight and 7.5% ferrous sulfat based on hydrogen peroxide weight. Hot pressing was applied for 12 min at 180ºC. Seven types of bamboo BP were produced based on the raw materials, i.e. the bamboo species namely; parring bamboo, betung bamboo, tallang bamboo, parring-betung bamboo with ratio 1 : 1, parring-tallang bamboo with ratio 1 : 1, betung-tallang bamboo with ratio 1 : 1, and parring-betung-tallang bamboo with ratio 1 : 1 : 1. The results indicated that the characteristics of betung bamboo BP were better than the two other bamboos. The physical and mechanical properties however have not fulfilled JIS A 5908 2003 yet. Differences in BP characteristics were caused by the chemical contents of bamboo, especially lignin that is different from species to species.

Abstract:
Abstract The potential use of sago pith waste, bamboo, and water hyacinth based on the characteristics of raw materials to make liner paper were studied. The analysis conducted covered the analysis of physical characteristics, chemical components, morphology (SEM), functional groups (FTIR), and crystallinity (XRD). The pulp from the three kinds of fiber was molded into paper with a certain formulation. The parameters of pulp and paper observed covered the alkaline consumption, Kappa number, pulp yield, and paper physical characteristics (grammage, bursting strength, Ring Crush Test/RCT, water content, and water absorption). The chosen paper was the paper whose characteristics resembled the quality parameter of liner paper used by the paper industry and the standard in accordance with the Indonesia’s National Standard (SNI) 14-0095-1996. The microscope images showed that the three said raw materials have long fibers: sago pith waste and water hyacinth has fibers measuring respectively 1.89±0.90 and 2.07±0.39 mm, resembling hard wood, whereas bamboos have longer fibers measuring 4.61±0.72 mm, resembling soft wood. Bamboos have the best fiber composition and characteristics for pulp and liner paper. The two paper formulas that meet the criteria for liner paper are bamboo and bamboo+water hyacinth.

Abstract:
In this study was about a comparison of geographic factors towards the characterization of petung bamboo in Indonesia and the Philippines. Bamboo is one of the plants that has advantages in the field of technical materials based on developments in composite materials and is found in various regions. In general, bamboo has lignin and cellulose, where the morphology and nature of both bamboos are not the same from different countries. Therefore,material testing was carried out on each Indonesian and Filipino petung bamboo using material characterization testing methods. The process of Differential Scanning Calorimetry (DSC) was carried out to measure calorimetry with the yield of melting point in Philippine petung bamboo at 341ºC which is lower than the melting point in Indonesian petung bamboo which is 354.34ºC. In this DSC test, quantitative and qualitative results were obtainedin the form of phase changes, melting, and transition temperatures that occurred. Then an Energy Dispersive Spectrometer (EDS) was analyzed and the carbon content of cellulose and lignin was higher in Indonesian petung bamboo, respectively 65.29 wt.% And 66.05 wt.%. The morphology of bamboo shows that the fibers and matrices present in Philippine petung bamboo are denser than those of Indonesian petung bamboo. The highest peak value based on X-Ray Diffraction (XRD) is found in Philippine petung bamboo at 2ș of 34.49 and cubic phase.

Abstract:
Bamboos generally have elasticity module in compression of about 9 GPa, which is a relatively low value compared to timber and concrete, 20 GPa, and steel, 200 GPa. However, the compressive strength is high - 40 to 80 MPa – that, combined with axissimetria of the cross section, makes the bamboos structural elements with high strength and flexibility. Considering the low apparent specific weight of the material 8 kN/m3, photosynthetic production and workability, bamboos have no competitor in the market so that loads can be absorbed independently by any of the above materials. But the industrial structural elements may be produced with dimensions and geometries provided in accordance with the load to be transported. This is not the case of bamboo. Thus, the capacity of the bamboo in compression becomes limited by its natural flexural rigidity, EI. Thus, different structural systems with pipe threads to make large columns or masts were investigated, [1,2], all with bamboo Phyllostachys pubescens species. In this paper, a kind of mast composed of a central bamboo 6 m in length and six smaller segments axi-symmetrically distributed around this central bamboo will be presented. This proposed design is organizationally a set of bars shackled by steel bands along the length of the beam. Flexion-compression tests with bamboo species Phyllostachys pubescens, combined with numerical modeling through the MEF were made. The loading capacity was tripled and the lateral deviations are negligible when compared with the axial bamboo tested alone. This mast, while consuming a relatively high number of bamboo units, has the advantages of ease and constructive possibility of structural use of smaller diameter bamboo. All the design and results of experimental and numerical analyzes will be discussed in this paper.

Abstract:
AbstractThis paper presents the characterization of laterite-cement-based matrix composites, reinforced with chemically modified bamboo fibers. Fiber extraction and chemical modification were first explored by soaking slabs of bamboos in NaOH solution (5 wt.% of NaOH in distilled water) for 14 days. Fiber characterization, as well as the flexural and compressive strength of reinforced composites, were carried out with MTS universal mechanical testing machine. Comparative results on the compressive and flexural strength were obtained at 80 wt.% laterite (L) to 20 wt.% cement (C) with fiber ratios from 5-25 wt%. The compressive strength of the composites varied from 7.2 MPa (at 5 wt.% bamboo fiber) to 17.67 MPa (at 25 wt% fiber blocks). The hardness of the composites was found to improve from 66.67-75.0 HD with bamboo fibers. Results were then discussed for possible structural applications such as enhancing low-cost building blocks for rural communities in Ghana.

Abstract:
Bamboo can be used in a variety of ways, including as fuel and as household and construction materials. Due to its versatility, the material is of high economic value. This study investigated the fuel properties of six bamboo species grown in Indonesia. Each bamboo sample was carbonized at different temperatures. Proximate and ultimate analyses were carried out on the bamboo samples. The thermal maturity of the bamboo samples as a solid fuel was investigated by the van Krevelen diagram. The efficiency of bamboo at each carbonizing temperature was determined based on the char yield, energy densification rate, energy efficiency, and calorific value. The results showed that the ash and fixed carbon contents of carbonized bamboo increased with an increasing carbonization temperature; while the volatile matter decreased. Significant changes in the fuel properties were observed between 200 °C and 400 °C. Carbonized bamboos showed lower sulfur contents in comparison to other fossil fuels. Ampel bamboo showed a calorific value of 18 MJ/kg to 32 MJ/kg, which was the highest value among the samples. Bamboo carbonized at temperatures above 600 °C showed a thermal maturity of coal grade. The results of this study can be used for utilizing Indonesian bamboo as a fuel source.

"Effect of drying schedules on the drying time and quality of Dendrocalamus barbatus bamboo using solar energy integrated with steam heated source." BioResources 19, no. 1 (December 12, 2023): 917–24. http://dx.doi.org/10.15376/biores.19.1.917-924.
Abstract:
Bamboo is recognized as a promising material. It is widely distributed in Vietnam. Bamboo products are quite diverse. However, bamboo materials have been primarily air-dried in open locations. Thus, the bamboo does not achieve the required moisture contents for use in certain products. This can lead to easily being infected by fungi, especially molds that affect the quality of the bamboo’s products. To date, bamboo drying using solar energy integrated with a steam-heated source has not been studied. This study investigated the effect of drying schedules on the drying time and quality of Dendrocalamus barbatus bamboos in “culm” and “strip” forms using solar energy integrated with steam-heated source. Higher temperatures yielded faster drying times, but they also created more drying defects in the bamboo because of the drying gradient being higher. However, depending on the manufacturer’s requirements, the drying schedule No. 1 (40 °C to 60 °C) or No. 2 (50 °C to 70 °C) can be used for drying the bamboo culms. In relation to the bamboo strips, drying schedule No. 3 (60 to 80 °C) is recommended because it was the shortest drying time and had a low defect rate (9%).

Abstract:
As a country of rich bamboo forest and large-scale bamboo processing industry, China is promoting the development of modified bamboo building materials and the bamboo construction systems. In the study on bamboo building envelope (BBE), as a hygroscopic construction, particular attention should be paid to the coupled heat and moisture (H&M) process. However, the parameters basis and the thermal design code in China could not yet support such calculation on coupled H&M process of BBE. In order to clarify the impact of meteorological parameters on the H&M process of BBE, the study prepares 24 representative cities in China with climate data exported from the Meteonorm platform and 3 typical bamboos with complete material properties data tested through experiments, and then sets up comparison BBE model groups in the software WUFI Plus for annual H&M process simulation. Statistical analysis clarifies the correlation law between the H&M process of BBE and the meteorological parameters. The study highlights the importance of hygric meteorological data for the application of BBE.

"Evaluation of surface properties of betung bamboo (Dendrocalmus asper) strands under various heat treatment duration and temperature." Journal of Science and Applicative Technology 5, no. 2 (October 13, 2021): 411. http://dx.doi.org/10.35472/jsat.v5i2.457.
Abstract:
The abundance, rapid growth characteristics and good mechanical properties have made betung bamboo as good alternative materials to replace the slow growing wood. To adress the susceptibility to insects and water attack, the making of bamboo composites, using resin as matrix, has been widely practiced. Thus, the surface properties of bamboo strands are crucial to determine the optimum interaction with resin. This study evaluate the effect of heat treatment to improve the surface properties of bamboo strands, such as the wettability and the color change. Beforehand, the freshly cut bamboo was cut, cleaned and sand-grinded. The heat treatment was done at 140o and 160oC for 1, 2, and 3 hours. After cooling down to room temperature, the contact angle of bamboo’s surface was measured by sessile drop methode. The wettability was indicated by constant of contact angle change rate, K. Besides, the change of color was also determined. After the experiments, it was obtained that the bamboo surface tends to be more hydrophobic and has darker color with longer duration of heat treatment. Higher temperature and longer duration of heat treatment can cause more evaporation of liquid inside bamboo and decrease hydrophilicity of the surface.

Abstract:
Abstract Bamboo roots are residual material from the utilization of bamboo trees’ waste. Bamboo roots utilize in engineering by making new materials in the form of composites. Bamboo roots are easy to get, and getting bamboo root fiber is relatively easy compared to getting bamboo stem fiber. Bamboo root fibers are used as reinforcement in composites with resin binders and catalysts as hardeners. The composite made by mixing the composition consists of 10% bamboo root fiber, 89% resin, and 1% catalyst from the weight of the specimen. This composition uses three variations of fiber direction; straight, random, and woven fiber—each variation tests tensile strength, impact, and bending strength. Those three test results show that the highest values come from the woven fiber, which are 21.04 MPa from the tensile strength, 0.0693 J/mm2 from the impact value, and 34.789 MPa from the bending strength value. The test result found that applying bamboo roots composite material suits dashboard material for light vehicles (cars and motorcycles). This test result meets the standard material for dashboard vehicles based on plastic material data ABS (Acrylonitrile butadiene styrene). This research on natural fiber composite material is novel and valuable as a waste utilization solution for engineering materials.

Abstract:
To improve practical application of modern bamboo structures, strengthening the bamboo engineering material is necessary to overcome insufficient stiffness. As an essential step in developing fibre-reinforced polymer–bamboo engineering material composite structures aimed at increasing the structural stiffness, the bonding behaviour at the interface of the fibre-reinforced polymer and bamboo engineering materials should be investigated in detail because currently there is a lack of research. In this article, bonding behaviour is studied between basalt fibre-reinforced polymer bar and bamboo engineering material including laminated and reconstituted bamboo and between basalt fibre-reinforced polymer sheets and laminated bamboo. Failure patterns are categorized, and the load–slip curves are discussed. Based on the failure pattern and strain variation, recommended bond lengths were proposed for the basalt fibre-reinforced polymer bar–bamboo engineering material and basalt fibre-reinforced polymer sheet–laminated bamboo composite specimens, respectively. In addition, a simplified three-phase bond–slip model was proposed for the basalt fibre-reinforced polymer bar–bamboo engineering material composite specimen.

Abstract:
Color is one of the most important characteristics of a material’s appearance, which affects the additional value of bamboo and psychological feelings of users. Previous studies have shown that the dimensional stability, mildew resistance and durability of bamboo were improved after tung oil thermal treatment. In this study, the effects of tung oil thermal treatment on bamboo color at different temperatures and durations of time were investigated. The results show that the lightness (L*) of bamboo decreased as the tung oil temperature or duration of time increased. The red–green coordinates (a*) and color saturation (C*) of bamboo were gradually increased as the tung oil temperature rose from 23 °C to 160 °C, while the a* and C* were gradually decreased when the temperature continued to rise from 160 °C to 200 °C. There was no significant difference in the yellow–blue coordinates (b*) of bamboo when the duration was prolonged from 0.5 h to 3 h with tung oil thermal treatment at 140 °C. Eye movement data show that the popularity of bamboo furniture was significantly improved at 23–100 °C and slightly improved at 160–180 °C with tung oil treatment. Therefore, tung oil thermal treatment plays a positive role in improving visual effects and additional value of bamboo.

"Fabrication Process Optimization of Gombong (Gigantochloa pseudoarundinacea), Haur Hejo (Bambusa tuldoides) and Tali (Gigantochloa apus) Bamboo Fibers for Structural Application." Key Engineering Materials 851 (July 2020): 172–83. http://dx.doi.org/10.4028/www.scientific.net/kem.851.172.
Abstract:
Natural fibers contained in bamboo are beneficial to renewable, biodegradable, abundant availability, and cheap which could be a potential substitute of synthetic materials. Tensile strength of this material is important requirements in various structural application. In this research, fiber fabrication process optimization of three types of local bamboo namely Gombong (Gigantochloapseudoarundinacea), HaurHejo (Bambusatuldoides), and Tali (Gigantochloa apus) was investigated. These fibers were processed by creating a variety of the NaOH concentrations of 4 % and 6 %, immersion times of 1, 2, and 3 hours, and immersion temperatures of 25 °C and 60 °C. The process parameters and its level variations of bamboo fiber fabrication were optimized using Taguchi method. Then the contribution of each process parameter was observed using the analysis of variance (ANOVA). From Taguchi method, the optimal parameter for highest tensile strength was obtained from Tali bamboo, indicated by 4 % NaOH, 2 hours immersion time, and 60 °C immersion temperature. Meanwhile, the ANOVA revealed that the contributions for each parameter are 70 % for bamboo type, 7 % for NaOH concentration, 4 % for immersion time, and 17 % for immersion temperature with error contribution of 2 %. By using these data, it could be concluded that bamboo type selection is a critical parameter to obtain bamboo with high tensile strength. While NaOH concentration, immersion time, and immersion temperature are not critical parameters which gave flexibility in the selection process. FTIR analysis was carried in order to observe chemical bonding in bamboos. The results of FTIR on the bamboo fibers were indicated Tali bamboo has larger lignin levels decreasing than HaurHejo and Gombong, this indicates in higher tensile strength for Tali bamboo fiber.

Abstract:
In light of continual societal advancement and escalating energy consumption, the pursuit of green, low-carbon, and environmentally friendly technologies has become pivotal. Bamboo, renowned for its diverse advantages encompassing swift growth, ecological compatibility, robust regenerative properties, commendable mechanical characteristics, heightened hardness, and abundant availability, has discovered applications across various domains, including furniture and construction. Nevertheless, natural bamboo materials are plagued by inherent limitations, prominently featuring suboptimal hydrophobicity and vulnerability to fracture, thereby constraining their broad-scale application. Thus, the paramount concern is to enhance the performance of bamboo materials through modification. However, prevailing reviews of bamboo modification predominantly concentrate on physical or chemical approaches, resulting in a conspicuous absence of a comprehensive overview of bamboo modification techniques. This review explores an array of bamboo treatment modalities and delivers a valuable assessment of bamboo modification, offering significant guidance for forthcoming bamboo enhancement and utilization endeavors.

Abstract:
The suitability of bamboo’s basic characteristics is very important for more specific purposes, such as composite raw materials. Anatomical, physical, mechanical, and chemical characteristics are some of bamboo’s fundamental characteristics. This study analyses the basic properties, such as physical, mechanical, and chemical properties of bamboo from the Forest Area with Special Purpose (FASP) Pondok Buluh Sumatera Island, Indonesia (I); analyses the relationship between the properties of each type of bamboo (II); and chooses the type of bamboo with the best properties that have the potential to be applied to composite materials, such as laminated bamboo (III). This study used materials consisting of six species of bamboo from the FASP Pondok Buluh. The manufacture of physical and mechanical test samples refers to the ISO 22157 standard, 2004, while the chemical properties test refers to the TAPPI 1999 standard. The chemical, physical, and mechanical properties of bamboo vary widely among species. The lowest holocellulose and α-cellulose content were found in the Kuning Bamboo (B. vulgaris var. vittata). The content of holocellulose and α-cellulose causes the lowest density in Kuning Bamboo (B. vulgaris var. vittata). The Dasar Bamboo (Bambusa vulgaris) has the highest levels of lignin. The substances have an impact on moisture content, T/R ratio, and shear strength. The Dasar Bamboo (Bambusa vulgaris) has the lowest moisture content, the highest T/R ratio, and the highest shear strength. However, Betung Bamboo (Dendrocalamus asper) has the highest density in this study. The compressive strength of the Betung Bamboo (Dendrocalamus asper) has the highest value. Therefore, Betung bamboo and Dasar Bamboo in this study were potentially utilized for composite materials, such as laminated bamboo.

Abstract:
A hollow bamboo in its raw state, from the geometrical point of view and language engineering can be defined as an element of tubular bar, not prismatic, approximately circular cross sections, stiff by intermittent internal disks positioned along the bar. The decrease in the diameter and wall thickness usually happens from the bottom up, the basal part may contain some exceptions, with sections of the base with diameters smaller than the second, then to diminish steadily to the top. This architecture has a genetic component that resulted from constant interactions of bamboo with the actions of wind, which stimulated increased local resistance of the most requested points mechanically, not only by concentrated lignification in cellulosic tissues, such as the geometric localized variations. From the viewpoint of composite materials science, bamboo can be defined as a composition of two different materials, a first fiber and vessels oriented and aligned along the internodal stem sections, which connect to another material with fibers and vessels tangled - anastonose - intermittent stiffeners composing the above cited nodes. In both materials vessels and fibers are surrounded by a parenchymathous matrix of hollow cells that store sugars. The mechanical point of view, bamboo, due to the configuration, the rigidity and strength components and a tubular geometry is a flexible structural element with high mechanical resistance. This flexibility makes the long elements have low load capacity in flexion compression, if the goal is the application of bamboo in construction structures. This issue can be circumvented by systemic compositions, called masts, [1,2] which can be applied in a single long bamboo element resistant to relatively high compressive loads. In the present investigation, four parallel bamboos 5.5 meters long, the speciesPhyllostachys pubescensare discontinuously connected by bamboo segments interposed fixed by steel pins, achieving this composition with a load limit of 48 kN in controlled experiments. These experiments were also used and motivated to find the numerical modeling by the MEF, whose results were widely discussed.

Abstract:
In this study, bamboo was treated with an optimized surface furfurylation process. With this process, dimensionally stable and highly biologically durable bamboo material could be prepared without mechanical reduction. The anti-swelling efficiency (ASE) could reach 50% with a low weight percent gain (WPG about 13%). By using SEM, nanoindentation, and Imaging FTIR, we demonstrated that this high performance improvement is attributed to the unique furfuryl alcohol (FA) resin distribution pattern in the modified bamboo, namely a higher concentration of FA resin located in the region near to the surface of bamboo, and what is more, the preferred distribution of FA resin within the cell walls of parenchyma cells, which is known to be the weak point of bamboo both for biological durability and mechanical performances. Such graded modified bamboo could be utilized as a reliable engineering material for outdoor applications.

Abstract:
Abstract - The issue of global warming strongly encourages architects to use sustainable materials to preserve nature. Bamboo material is an ecological and sustainable material. Bamboo is also predicted as a future material. The strengths and advantages of bamboo are very likely to be used as a building construction material. Unfortunately, it is not uncommon for bamboo material to be used inappropriately so that it does not optimize the ecological and sustainable properties of bamboo. The object of study chosen was the Bumi Pemuda Rahayu bamboo hall. This object is close to the concept of sustainability as seen from the function of the building, which is a co-creating space that prioritizes sustainability-related activities.
This research uses qualitative-quantitative methods that will compare the theory regarding the concept of sustainability of materials related to the building material life cycle with the data obtained. The concept will be divided into three aspects, namely design aspects, construction aspects, and maintenance and renovation aspects. These three aspects can be examined by knowing the object data related to these aspects. The results of the study will answer whether the use of bamboo material in the object of study is in accordance with the concept of sustainability of the bamboo material.
The analysis of the design stage pays attention to material selection, material preservation, how to optimize the age of bamboo and the selection of a structural system. The construction stage is analyzed by considering the type of connection used. The maintenance and renovation phases are analyzed by paying attention to how to renovate the bamboo structure and post-construction maintenance of the building.
This building is appropriate in choosing the type of material, applying preservation of bamboo materials, and successfully preventing bamboo from environmental influences in order to reach its optimal age. In terms of structural system selection, this building is also appropriate by applying the arc rod structural system. Bolted joints are appropriate for complex structural systems, it's just that there must be special treatment at the base of the arc structure that receives the greatest load due to cracks. Renovation and maintenance aspects must be considered again because this building will have difficulty if you have to do renovations, especially on the arc structure. Maintenance that is rarely performed can also reduce the life of the building.

Abstract:
Bamboo is generally widely used as a material or construction material in homes. However, the use of bamboo as a raw material for shipbuilding is not yet available. To make bamboo as a material in shipbuilding, the bamboo is assembled or made into a composite to meet class standards as a material for shipbuilding. In this study, the composites used were apus bamboo fiber and asphalt. The method of making the composite uses the hand lay-up method with variations of 1 layer of reinforcement, 3 layers of reinforcement, and 5 layers of reinforcement. The dimensions of the test specimen size refer to ASTM D 790-3 which is then carried out by bending tests to determine the strength of the material due to loading and the elasticity of the material. Furthermore, the results of the bending test will be analyzed using the Anova method and compared with the standard material class in ship construction. Results Asphalt composite material with apus bamboo fiber has the highest bending test value of 27,068 Mpa and the lowest bending test value of 25,998 Mpa. Based on these results, it is stated that the Bamboo reinforced asphalt (BRA) material has not been able to match and even exceed the Bamboo reinforced plastic (BRP) material in the woven, non-woven and random fiber variants. It is influenced by the diameter, and the strength of the shape between the fiber and the matrix.

"Preparation and evaluation of thermo-regulating bamboo fabric treated by microencapsulated phase change materials." Textile Research Journal 89, no. 16 (November 18, 2018): 3387–93. http://dx.doi.org/10.1177/0040517518813681.
Abstract:
Two types of microencapsulated phase change materials (ENPCMs) were synthesized by polymerization. The core material of ENPCM was n-octadecane and the shell materials were polymethyl methacrylate-butyl acrylate and polymethyl methacrylate-butyl acrylate-hydroxyethyl methacrylate. Subsequently, the synthesized ENPCMs were applied onto bamboo fabric by the dip and dry method. The properties of ENPCMs were analyzed in terms of surface morphology, size distribution and latent heat; the treated bamboo fabrics were evaluated in terms of surface morphology, hydrophilicity, washing fastness and heat storage capacity. The results showed that polymethyl methacrylate-butyl acrylate/ n-octadecane (PMBO) microcapsules had an irregular shape, while polymethyl methacrylate-butyl acrylate-hydroxyethyl methacrylate/ n-octadecane (PMBHO) microcapsules were spherical, and the mean diameters of both microcapsules were less than 1 µm. The latent heat of phase change material (PCM) microcapsules was almost the same at a thermal storage capacity of 110 J/g. There were many more and more even PMBHO microcapsules deposited on bamboo fabric than that of PMBO microcapsules deposited on bamboo fabric. Bamboo fabrics treated by both microcapsules were hydrophilic, and the hydrophilicity of fabric treated by PMBHO microcapsules was even better. The ratio of PCM microcapsules to bamboo fabric was about 1:4, and the latent heat of treated bamboo fabrics was about 20 J/g. Moreover, the treated bamboo fabrics exhibited excellent washing fastness due to the strong binding strength between the highly hydrophilic microcapsules and bamboo fibers. Approximately 72% of PCM microcapsules were retained on the fabric after 15 washing cycles.

Abstract:
Bamboo building envelope (BBE) is a kind of hygroscopic construction, making it necessary to describe the coupled heat and moisture (H&M) process accurately. In order to clarify the impact of material parameters on the H&M process of BBE, the study sets up BBE comparison model groups in WUFI Plus for annual coupled H&M process simulation, with exterior walls of 3 typical bamboos as boundary conditions and climate data of 24 Chinese representative cities as external conditions. Results quantitatively show the factor impact of hygrothermal properties parameters on the annual moisture content, heat and moisture exchange of the bamboo exterior walls, as well as the HVAC demand and indoor hygrothermal environment of the bamboo enclosed space. The simulation without liquid water-related parameters results in significant underestimation of moisture content and moisture exchange, and causes evident deviation to the heat exchange and HVAC demand. The constant valuation of thermal parameters and hygric parameters lead to deviation in heat process and moisture process of the BBE, respectively. The study highlights the moisture content-dependent bamboo hygrothermal parameters for the application of BBE.

Abstract:
Bamboo a giant, fast-growing, wood like grass appears to be the most successful and diverse conspicuous group of plants belonging to the sub family Bambusoideae of Poaceae. Bamboos have strong adaptability and are distributed widely in varied habitats. They are one of the earth’s oldest and most precious plant materials and have benefited human societies since time immemorial. They form an important group of plants that play a vital role in the economy and life of the people in many Asian, African and American countries. Bamboos play a key role in the rural economy of India. Due to the special physical characteristics attributed to bamboo, it has a glorious past and a promising future as part of the solution to 21st century challenges. Globally, bamboo is being targeted for livelihood development and alleviation of both environment and social problems in such a way that it can rightly be called the plant of the century.
Taxonomically, bamboos are considered as one of the most difficult group of plants to identify. Despite of immense resources, its importance and species specific uses, taxonomy of Indian Bamboos is still incomplete. Many of the Indian species lack full description and are either partially known or misidentified due to lack of subject expertise. Different workers treat species differently which has resulted into ambiguous report of generic and infrageneric taxa. An updated account of the bamboos found or reported from India is presented here after an extensive taxonomic study of these valuable natural resources of our country.

Abstract:
Abstract There is a rising gap between supply and demand of wood as building and construction materials. The search of alternative materials to fill in the gap is an urgent concern. Bamboo is one of locally abundant resources; 88 out of 135 species growth in Indonesia is an endemic. It is a renewably material and has comparable characteristics to wood. Notable efforts to reduce the variability of raw bamboo have led to the improved physical and mechanical properties of the engineered bamboo. Laminated bamboo and hybrid laminated bamboo-wood had superior wood strength in comparison to the raw materials. Laminated bamboo produced from andong (Gigantochloa pseudoarundinacea (Steud.) Widjaja), mayan (Gigantochloa robusta Kurz), vertically laminated andong bamboo comparable to wood strength class I, I-II and II, respectively. Furthermore, hybrid laminated bamboo-wood andong-manii (Maesopsis eminii Engl.), andong-mayan-jabon (Anthocephalus cadamba (Roxb.) Miq.) comparable to wood strength class II and III, respectively. The properties improvement of engineered bamboo demonstrates the potential application of laminated bamboo as a substitution for building and construction material.

Abstract:
As a renewable biomaterial, bamboo has been widely used in construction and indoor decoration. While the application of bamboo is limited by its low decay resistance and flame retardancy, the combination of modification with boric acid and borax has been found to be effective for improving bamboo flame retardant. In this study, the decay resistance, mechanical properties, and physical properties of bamboo, both before and after treated being with boric acid and borax (in a 1 to 2 ratio), were analyzed to better utilize the modification solution for bamboo. The results showed that in comparison to the untreated bamboo, the treated bamboo had a strong decay resistance, i.e., greater than 80% resistance effectiveness improvement. In addition, the decay resistance and compression strength of the samples showed a considerable increase, i.e., 21%, after the modification. However, the physical properties e.g., the weight gain, equilibrium moisture content, and dimensional stability and bending properties of the bamboo were less affected by the modification method, which could be improved via the combination with another chemical modification agent.

Abstract:
The effect of chemical activation on the adsorption of metals ions (Cr2+, Cu2+, Ni2+, Pb2+, Fe2+, and Zn2+) using waste Nigerian based bamboo, coconut shell, and palm kernel shell was investigated. The bamboo, coconut, and palm kernel shell were carbonized at 400°C–500°C and activated at 800°C using six activating agents. Chemical activation had significant effect on the iodine number and invariably increased the micropores and macropores of the activated carbons produced from bamboo, coconut, and palm kernel shell. It also affected the adsorption of metal ions and the type of carboneous material used for activation. The highest metal ions adsorbed were obtained from bamboo activated with HNO3. The cellulose nitrite formed during the activation of bamboo with HNO3 combined with high pore volume and low ash content of bamboo effectively create more reaction sites for adsorption of different metal ions. This shows that waste bamboo activated with HNO3 can effectively be used to remove metal ions from waste streams and in different metal recovery processes than activated carbon from coconut shell and palm kernel shell.

Abstract:
ABSTRACTFour decades of advanced research about Non-Conventional Materials and Technologies (NOCMAT) such as bamboo and composites reinforced with natural fibers have shown that it is now possible to produce and use high performance NOCMAT. Bamboo and composites reinforced with vegetable fibers are capable, meeting most engineering demand in terms of strength, stiffness, toughness and energy absorption capability. The greatest challenge of the 21st century is the need for cost-effective, durable and eco-friendly construction materials that will meet the global needs of infrastructure regeneration and rehabilitation which alone can enhance the quality of life for all the people of the world. This paper summarizes some results of judicious combination of different matrix reinforced with vegetable fibers, especially bamboo. These sustainable ecological materials are strong, ductile and capable of absorbing large amounts of energy. They could find extensive applications in the engineering particularly in developing countries. Specifically, the development of durable composites reinforced with vegetable fibers and bamboo poses an important challenge to the science and skills of engineering. This challenge could create the most useful, eco-friendly construction materials backed by an endless supply of renewable natural resources. In addition the paper presents results of some ongoing research concerning bamboo and how vegetable fibers such as hemp plant, before the invention of Nylon was the most used materials in all aspects of human life around the globe and why it was banned.

Abstract:
Compositions with different pipe segments for constructing structural columns were investigated. In this article there is shown a column type composed of five parallel bamboo bars, connected by screws 16 mm and 13 mm in diameter. Compression tests instrumented with displacement transducers are associated with numerical modeling analysis to describe the column load capacity, from the general criteria of dimensioning. The chosen Bamboos are from the species Phyllostachys pubescens due to its favorable characteristics to produce structures and their common use in China, Brazil and other countries of temperate zones. In this proposal, the load capacity is considerably increased and lateral displacements are insignificant compared to the bamboo tested separately. More usual columns 3 and 4 meters long were modeled and presented the load limits of use for these types of structures. Other dimensions of columns can be calculated by the same system, presenting great design opportunities in the construction of the architecture and built spaces. This article shows a great advantage in using columns with bamboo bars compared to other materials used in the architecture, with guarantee and good indexes of security.

Abstract:
Serdam is an artistic product in the form of a wind instrument, the only one in West Lampung and made of bamboo. Serdam is usually used to accompany oral literary vocals such as muayak, hahadoh, hahiwang and dance music along with other traditional Lampung musical instruments. The bamboo used for the manufacture of Serdam is bamboo of the type of bamban and is often found in the plantations of the people of West Lampung. The purpose of this study is to describe the physical form, tools and materials, the process of making Serdam, sound source and tone system and how to play the Serdam. Serdam has many physical similarities to bamboo wind instruments from other regions, but Serdam has a distinctive blowing technique and tone. The research method used is the descriptive qualitative research method. The data obtained from this study with data collection methods by observation, interviews and documentation studies. The results of this study indicate that the Serdam wind instrument is made of bamboo bamban which is often found in the plantations of the people of West Lampung. Serdam has a shape like a long tube that has four melody holes and one blow hole. This musical instrument still uses a traditional manufacturing process to this day. Serdam as the only wind instrument originating from West Lampung has many organological peculiarities that are not yet known by the supporting community.

Abstract:
Bamboo is a versatile plant and occupies a special place in the life of indonesian people. Bamboo is also a fairly available and inexpensive raw material for making household appliances and furniture, building materials, pipes for water distribution, musical instruments and religious purposes. In addition, some types of bamboo are ornamental plants and waste filter processors and erosion prevention. Bamboo belongs to the results of non-timber forests and can be used as an alternative to wood. This research aims to find out the diversity of bamboo plants and the form of utilization of bamboo plants in Cobodoe Village, East Tidore Subdistrict. This research is a descriptive study, with survey methods used to describe the diversity and form of utilization of bamboo plants in Cobodoe Village, East Tidore District. The results of this study showed that the diversity of bamboo types in Cobodoe Village was categorized as low with an H' value of 1.03. There are three types of bamboo, namely Spotted bamboo (Bambusa maculate), Bamboo Tui (Melocanna hamilis Rpr.), and Bamboo Fence (Bambusa glaucescens). People in Cobodoe Village use bamboo plants as raw materials for food and household furniture.
