Abstract:
This research was conducted to observe the consortium cellulose enzyme activity that bacterial comes from oil palm empty fruit bunch waste. The use of bacterial isolates derived from oil palm empty fruit bunch waste is expected to have a good effect, because the bacteria have been adapted to live in a waste environment that has a high concentration of organic matter. The purpose of this study was to determine the activity of cellulose enzyme consortium of bacteria from palm oil waste in the process of biodegradation of oil palm empty fruit bunch waste (Elaeis guineensis Jacq.). The method used is descriptive method. The oil palm empty fruit bunch substrate was fermented and then cellulose enzyme activity was tested using the Somogyi-Nelson method. Doses of bacterial inoculums used in this study were 5% and 10%.

Abstract:
Railway brake block is one of the most important components of the braking system of a railway vehicle. Materials for railway brake blocks are commonly made from metal or composite. The metallic brake blocks have some disadvantages that are heavy, low wear-resistant and has potential in generating a spark. While the composite brake blocks do not have those disadvantages. Natural fiber from oil palm empty fruit bunches as the waste from the production of palm oil can be used as a composite constituent. This composite brake blocks made from oil palm empty fruit bunches as reinforcement, phenol resin as matrix, and alumina, magnesium oxide and iron powder as a friction modifier. Density, hardness, coefficient of friction, compressive strength and flexural strength tests were carried out to determine the mechanical characteristic of the composite railway brake block material. The railway brake block test results consist of the density of 1.96 g/cm3, the hardness of 57.6 HRB, coefficient of friction of 0.43, the compressive strength of 37.1 MPa, and flexural strength of 33 MPa. There are three samples of volume fraction combination with 20% of oil palm empty fruit bunch in sample 1, 15% oil palm empty fruit bunch in sample 2 and 10% oil palm empty fruit bunch in sample 3. Percentage of MgO is adjusted to compensate the volume fraction of oil palm empty fruit bunch in the sample. Sample test results show that composite with volume fraction 10% of oil palm empty fruit bunch, phenolic resin of 30%, Al2O3 of 25%, MgO of 20%, iron powder of 15% has better mechanical properties for the alternative composite railway brake block material as compared to the other two.

Abstract:
The study is aimed at investigating the thermal behavior and decomposition kinetics of torrefied oil palm empty fruit bunches (OPEFB) briquettes using a thermogravimetric (TG) analysis and the Coats-Redfern model. The results revealed that thermal decomposition kinetics of OPEFB and torrefied OPEFB briquettes is significantly influenced by the severity of torrefaction temperature. Furthermore, the temperature profile characteristics; Tonset, Tpeak, and Tend increased consistently due to the thermal lag observed during TG analysis. In addition, the torrefied OPEFB briquettes were observed to possess superior thermal and kinetic properties over the untorrefied OPEFB briquettes. It can be inferred that torrefaction improves the fuel properties of pelletized OPEFB for potential utilization in bioenergy conversion systems.

Abstract:
Crude palm oil, consumed as a healthy food oil, contains a 3-monochloro-propane-1,2-diol (3-MCPD) ester in the range of 0.04-0.05 ppm. The 3-MCPD compound is one of the contaminants belonging to the chloropropanol group that is genotoxin carcinogen. It is therefore necessary to develop an integrated palm oil refining through adsorption with a modified palm empty fruit bunch bioadsorbent to reduce 3-MCPD ester (<2 ppm / Codex Standard). Response Surface Method applied in the optimization study of the modified empty fruit bunch of oil palm. The research was designed by using Central Composite Design. The parameter process studied were temperature (60-800C), time (20-40 minutes) and oil volume (400-600 ml). Response surface of the pressurized liquid water extraction of curcumin was expressed by a second-order polynomial. The research showed that temperature was the most influencing variable for the adsorption of 3-MCPD from modified empty fruit bunch of oil palm. The response surface contour plots of the RSM on the effect of temperature, time and oil volume have showed that the optimum condition for the adsorption of 3-MCPD from modified empty fruit bunch of oil palm were adsorption performed at temperature of 86.80C, 46.81 minutes and oil volume of 668.17 ml.

Abstract:
The increase of palm oil production produced waste, which has an impact on the environmental burden. Therefore, the purpose of this article is to predict the amount of palm oil empty fruit bunches produced per month in Indonesia to determine the potential of empty fruit bunches management. The predicted amount of the waste is based on crude palm oil (CPO) forecasts analysis that is processed using exponential triple smoothing. Based on the analysis, it was obtained that the amount of waste of empty fruit bunches proved to be directly proportional to the crude palm oil production. The efficiency of mill operation plays an essential role in CPO production and waste generation. However, this study has less variance on empty fruit bunches production since that quantity derived directly from CPO forecasting results based on fresh fruit bunches processed in the mills. Based on the estimation quantity, the management of palm oil empty fruit bunch as a raw material of fertilizer is sufficient to manage the produced empty fruit bunch. The data can be used to consider the waste palm’s potential management in palm oil mills and national scope.

Abstract:
Oil palm empty fruit bunch is abundantly available as waste from palm oil processing which is only used for boiler fuel and plant fertilizers. This study aims to investigate the utilization of oil palm empty fruit bunch as a composite reinforcement material to be applied as a raw material for the outer shell of Indonesian national standard (SNI) helmets. The materials used include oil palm empty fruit bunch, the polyester resin of BQTN yukalac, and the catalyst of MEKPO. The manufacturing process uses the hand lay-up technique by varying the fiber volume fractions 3, 6, 9, 12%, and therefore the fiber size passes mesh of 20 and 50. The tensile test uses the ASTM standard D 638 while the impact test uses the ASTM standard D 5942. Fiber volume fraction and fiber size affect the mechanical properties of oil palm fiber reinforced composites. The results of the tensile and impact tests showed that the highest tensile strength and impact toughness were obtained within the composite with a fiber volume fraction of 6% and a mesh of 50, which were 34.74 MPa and 60.21 kJ/m², respectively. In comparison with the tensile strength of the SNI helmet of 33.93 MPa, the oil palm empty fruit bunch fiber can be used as a composite reinforcement for the outer shell of the SNI helmet.

Abstract:
Oil palm empty fruit bunch (EFB) is one of the major solid wastes from palm oil processing. EFB is a lignocellulosic biomass and has the potential to be converted into microbial oil through biochemical routes, where the oils can be further used for biodiesel production. This PhD research aimed to develop and optimise a process for microbial oil production from EFB. The microbial oil production process involves cultivation by oleaginous microorganisms including microalgae, yeasts and fungi on EFB hydrolysates as carbon substrates. The study demonstrated that EFB is a promising low cost non-food feedstock for biodiesel production. The integration of microbial oil production from oil palm biomass with existing palm oil processing could enhance the profitability and sustainability of the palm oil industry.

Abstract:
The oil palm industry in Malaysia is striving to show that it uses a sustainable approach in order to be accepted internationally and ensure palm oil remains a major commodity in Malaysia. The Malaysian government has already prohibited the burning of oil palm wastes leaving a problem of waste disposal. In this work the cultivation of edible mushroom (Pleura/us sajor-caju) on unsterile oil palm waste empty fruit bunch (EFB) followed by vermicomposting by Eisenia fetida and Dendrobaena veneta is investigated as a sustainable approach to dealing with a major component of the waste. Two stages of treatment are required due to the lignin content, the C:N ratio (54: 1), the high level of total phenolic compounds (31.10 g GAE/1OOg extract, of which 1.35 mg/kg is phenol) and low phosphorous, and potassium in EFB which makes this material resistant to natural degradation (and hence unsuitable for standard composting) and hazardous to earthworms. Biological efficiency (BE) for the production of the edible fungal fruiting body (oyster mushroom) was more than 20% and an indication that the commercial bioconversion of EFB to mushroom is feasible. Thermogravimetric analysis (TGA) showed degradation of hemicellulose, cellulose and lignin and reduction of total phenolic compounds. No trace of phenol was found in extracts of EFB after fungal growth (GC-MS analysis). Treated EFB (i.e. after fungal growth) was found to be suitable for vermicornposting. The nutrient contents (TKN, P, N, Ca, Mg, Na and K) of the vermicornpost compared favourably with commercial high and low organic content compost. The final C:N ratio of the vermicompost was approximately 17: 1. This is an indication of stabilisation of the vermicompost and its suitability as a growth medium and soil enhancer. ICP-MS analysis showed that potentially toxic elements (Cr, Cu, Ni, Pb and Zn) of vermicomposted EFB were below the BSI:PAS:lOO:2011 limits. Seedling germination tests shows fast germination of tomatos, peppers and broad beans in a mixture (50%:50%) of vermicomposted EFB and low organic content compost. However seedling germination in vermicomposted EFB without additional compost was slow. It was concluded that oil palm waste (EFB) can be treated by a combination of Pisajor-caju cultivation and vermicomposting. Edible mushrooms can add to the economic balance of the treatment process and the ability to use unsterilised EFB will reduce costs. The final vermicomposted EFB also gives extra economic value and a beneficial return to the environment as a natural soil treatment material

Abstract:
The application of crop residues is one of the most common agricultural practices used to maintain soil ecosystems and crop productivity. This thesis focuses on the oil palm (Elaeis guineensis) agroecosystem, an important tropical crop that has expanded rapidly over the past four decades. Both land conversion and business-as-usual practices within the plantations have contributed to soil degradation. The application of oil palm residues, such as empty fruit bunches (EFB) and oil palm fronds, are thought to have positive effects on the soil ecosystem; yet there is currently a deficit of knowledge on their effectiveness. This thesis aims to examine the effects of oil palm residue application on soil physicochemical properties, soil biota, and ecosystem functions. It reports the results of extensive field trials, sample collection, and statistical analysis of crop residue applications in oil palm plantations in Central Sumatra, Indonesia. Four key results emerged from the thesis. First, in this study site land conversion from secondary forest to oil palm does not affect litter decomposition rate, but positively influences soil fauna activity. Second, there is greater soil fauna activity following EFB application than oil palm fronds or chemical fertilizers, and the fauna activity is highly associated with changes in soil chemical properties and soil moisture conditions. Third, EFB application enhances soil ecosystem functions, through the direct provision of organic matter, and by influencing soil biota. Finally, over 15 years of application, EFB appears to be effective in maintaining or increasing annual crop yield in comparison to chemical fertiliser treatment. Temporal changes in crop yield under EFB application appear to be associated with climatic conditions and soil organic carbon. Overall, these findings improve our understanding of the potential of oil palm residue applications to increase soil quality, soil biota, and ecosystem functions. They also provide useful information for a wider audience of soil ecologists, agricultural managers, and policy makers to improve sustainable management of the oil palm ecosystem.

Abstract:
A large part of energy carriers and chemicals of our society come from fossil fuels; due to their critical exploitation and environmental concerns, alternative solutions should be promoted. The goal of this work is to understand the environmental impacts of different supply chains of levulinic acid production. To enable this comparison, a cradle-to-gate LCA was conducted on different kinds of biomasses, under an innovative thermochemical process called Biofine. The study concerns biomass not only of agri-food origin (corn stover, barley straw, wheat straw), but also deriving from the waste collection supply chain (organic fraction of municipal solid waste). Results show that biochemicals production from waste-derived biomass represent the lowest environmental impact solution, compared to the supply chain with biomass of agri-food origin. For agri-food biomasses, the impacts deriving from the agricultural phase are orders of magnitude more significant than those of the industrial phase, while the transport phase is the least impacting in absolute terms. For waste-derived biomasses, transport is the most impacting phase of the entire supply chain.

Abstract:
Palm oil empty fruit bunches (EFB) is an abundant and cheap lignocellulose material in South East Asia. Its use as the sole medium for producing lignocellulose-hydrolyzing enzymes would increase its commercial value. A newly isolated Aspergillus niger DSM 26641 was investigated for its capability of producing hemicellulases in EFB hydrolysate obtained by treatment with pressurized hot water (1-20%, w/v) at 120-180◦C in a 1 L Parr reactor for 10-60 min. The optimal hydrolysate for the fungal growth and endoxylanase production was obtained when 10% (w/v) of empty fruit bunch was treated at 120◦C or 150◦C for 10 min, giving an endoxylanase activity of 24.5 mU ml-1 on RBB-Xylan and a saccharification activity of 5 U ml-1 on xylan (DNS assay). When the hydrolysates were produced at higher temperatures, longer treatment times or higher biomass contents, only less than 20% of the above maximal endoxylanase activity was detected, possibly due to the higher carbohydrate concentrations in the medium. Transcriptome analysis showed that 3 endoxylanases (expression levels 59-100%, the highest level was set as 100%), 2 b-xylosidases (4%), 4 side chain-cleaving arabinofuranosidases (1-95%), 1 acetyl xylan esterase (9%) and 2 ferulic acid esterases (0.3-9%) were produced together.

Activated carbon (AC) is regarded as one of the most promising active materials for high performance supercapacitor (SC) owning to its high specific surface area and theoretical specific capacity. In this study, oil palm empty fruit bunch (EFB) which is the agricultural residue was employed as precursor to produce ACs which were fabricated by a series of cleaning, carbonization and chemical activation processes. The as-produced AC possesses a specific surface area of 2774 m2/g, which is very high among the AC produced from biomass materials. In order to enhance the performance of SC, the AC was modified by nitrogen doping treatment. The specific capacity of AC and nitrogen-doped AC were 182 to 215 F/g, respectively, at a current density of 0.5 A/g in 6M KOH aqueous electrolyte. We demonstrated that the agriculture waste can be processed to become activated carbon with a high specific surface area for SC application.

Co-combustion of PEFB and coal can make up for the adverse effects of high pollutant and high ash content of coal. Oxy-fuel combustion and CO2 capture from flue gases is a near-zero emission technology that can be adapted to both new and existing pulverized coal-fired power stations. In this study, the combustion characteristics of PEFB, Australian coal and their blend with various blending ratios were studied. The results indicated that replacing N2 by CO2 in the combustion atmosphere with 21% of O2 caused increase in the ignition temperature and burnout temperature. When the O2 concentration was increased to 30%, the ignition temperature and burnout temperature were lower than in the air case. A slight decrease in the ignition temperature and a significant reduction in the burnout temperature was observed after the addition of PEFB, this trend became more obvious as the blending ratios were increased. The emissions of NOx and SO2 during oxy-fuel combustion were lower than under air-firing conditions. The reaction rate constant of combustion process calculated by Coats-Redfern method for 21%O2/79%CO2 are slightly lower than for 21%O2/79%N2. There was a synergistic effect for the co-combustion of PEFB and Australian coal, especially in the char oxidation stage.

Abstract:
AbstractThe smallholder perception and adaptation of climate-smart practice has been rarely addressed. More precisely, on oil palm smallholder whose plot was frequently accused as driving force of ecosystem service depletion. The study to reveal stakeholder perception and its implementation towards biomass utilization was performed in the case study of North Sumatera Province. The Labuhan Batu, Batu Bara, Langkat, and Serdang Bedagai District was selected as the sample cases where the oil palm concessions were highly overlaid. The first phase of the study was conducted by text mining analysis to decode smallholder, practitioner, and expert’s perception and sentiment against oil palm biomass products within the SMEs scheme. The next phase of implementation was operated by introducing biomass-driven oil palm products such as empty fruit bunch briquette, oil palm fronds pellet, midrib handicraft, oil palm based-livestock feed, empty fruit bunch oyster mushrooms, oil palm juice brown sugar, oil palm-laminated wood, and empty fruit bunch-compost. The feasibility and preferences among those eight alternatives were then assessed by multi-criteria decision-making tools named Analytical Hierarchy Process (AHP) based on its benefit, opportunity, cost, and risk features. The text mining analysis discovered that initially, the smallholders were perceived to have a lower interest in making use of biomass products as they presumed that it still marginalize farmers. It was also still unclear whether they realize and understand the potential of biomass utilization to ameliorate nature. After the time of implementation, they were enlightened and chose oil palm midrib handicraft over other alternatives as their pluri-activity. Having said that, it is necessary to keep promoting climate-smart adaptation practices at the local level for the sustainability of people, profit, and the planet.

Abstract:
In developing future electrical networks, it is crucial to develop new alternatives insulating materials which can improve the performance of the next generation high voltage cables. The high electric field reduces the resistance of solid insulation and causes partial discharge occurs through the impurities in a dielectric where this phenomenon causes ageing to the dielectric and ultimately leads to breakdown. Thus, this paper seeks to analyse the electric field intensity of High Density Polyethylene (HDPE) when added with 10%, 20% and 30% of different types of bio-filler such as coconut coir fibre, pineapple leaves fibre, and oil palm empty fruit bunch. This can be achieved by creating a two-dimensional (2D) axisymmetric electrostatic model by using the Finite Element Method Magnetics (FEMM) 4.2 software. The results showed that the inclusion of bio-filler in HDPE increased the maximum electric field intensity when compared with unfilled HDPE. The electric field intensity also varied with the different percentages loading of biocomposite and their permittivity. As a result, the maximum electric field intensity was much lower for HDPE added with a 10% loading of the oil palm empty fruit bunch. Hence, oil palm empty fruit bunch was the best composition as it tends to improve the dielectric properties since it has a lower electric field intensity at the top sphere electrode as compared to other compositions.
