Abstract (sommario):

Abstract Sago is an alternative food source crop, especially in Southeast Sulawesi. From year to year, the area of sago crops tends to decrease due to conversion and limited cultivation levels. Therefore, to preserve sago, it is necessary to identify and characterize sago growing in Kendari Peninsula. This study aims to identify and describe morphologically the types of sago found in sago-producing centers in the Kendari peninsula, Southeast Sulawesi. Observations were made on the different types of sago growing at two locations of sago planting centers. Parameter measurements were carried out on stem height, bark thickness, leaf width, leaf length, stem diameter, harvest age, and production per stem. The results showed that there were four types of sago found, namely roe (Metroxylon sagu R.), runggamanu (Metroxylon rumphii M.), and barowila (Metroxylon longispinum M.) and sago rui (Metroxylon microcantum). There are differences in sago vegetative and generative growth due to differences in growing environmental conditions and local climate. In general, the dominant types of sago in both locations were sago roe (Metroxylon sagus R.) and sago runggamanu (Metroxylon rumphii M.).

Abstract (sommario):

Sago plants (Metroxylon sp) is a type of palm tree that grows around swamps and waterlogged land in the tropics. Sago palms grow on muddy land, with the quantity of water varies greatly, ranging from dry land to land remained logged. The longer the land flooded, the growth of young plants (shoots / seedling) very rapidly, but the growth of the trees are very slow. This study aims to determine the relationship of the growth of sago (Metroxylon sp) with climatic factors (humidity, temperature, light) and biotic (plants or other vegetation). The results showed that the relationship of growth of sago with environmental factors, edaphic (water), climatic (humidity, light) and biotic factors (vegetation) are generally water has an influence on the growth of sago while the humidity factor for all types of places to grow, that is, the area stagnant water, temporary areas and dry areas do not affect the growth of sago.

Abstract (sommario):

Sago palm (Metroxylon sago Rottb.) is one of the carbohydrate-producing crops that has great potential in supporting food security programs. This study aims to determine the morphological and genetic diversity based on the mat-K gene marker of 15 accessions of sago pal that have been collected by the Sago Research Consortium. This research was conducted by preparing plant samples, extracting DNA, amplifying DNA with a PCR tools, visualizing the results of DNA amplification, sequencing, editing DNA sequencing, and blasting. The results showed that the sago palm accessions collected by the UNIPA Sago Research Consortium were morphologically different in the Russet stages. Based on the maturase K (mat-K) gene marker of 15 sago palm accessions were divided into two haplotypes, namely haplotype 1 which experienced deletion at base number 5 (amino acid phenylalanine) and haplotype 2 which did not experience deletion so it had phenylalanine amino acid. Phylogenetic analysis showed that 15 sago palm accessions were divided into 2 groups, namely group 1 and group 2. Sago palm were observed closely related to Metroxylon warburgii with genetic distance of 0.001.

Abstract (sommario):

Sago palm (Metroxylon sagu) plays a vital role in the Papuan indigenous community’s social, economic, and cultural life. It is a source of staple food, household income, and embedded cultural values. This research aimed to determine the extent of sago palm habitat spread using spatial data. The classification method and multispectral imaging were used by employing satellite imagery (Landsat 8 and Quick Bird) and field surveys. The sago forest coverage in Yapen islands was 87.73%, located between 9–50 masl, covering 9,456.26 ha. The results revealed that 43.53% of the habitat lies in the inclination of 2–8% (extreme gentle slope), covering 4,692.45 ha. Sago forest was found in a gleysol soil type with precipitation of 3,000-3,100 mm. The sago forest distances of 0–250 m and 251–500 m to the coastline showed that the habitat covers an area of 153.87 ha and 368.19 ha. The preferable area in this category is Raimbawi Subdistrict, followed by Kosiwo, and the less suitable area, or the marginal land, is in Windesi Subdistrict.

Abstract (sommario):

Biomass substrates have been used extensively in the production of biofuel by the simultaneous saccharification and fermentation (SSF) method. Biomass sources from the plant are preferable to produce biofuel because of the high sugar content. Adapting the SSF method, this work reported on the direct energy conversion from Metroxylon sagu via multienzyme catalysis in an enzymatic biofuel cell (EBFC). Metroxylon sagu locally called Sago is an industrial crop mainly found in Mukah, Sarawak. Sago is a type of starch that consists mainly of amylose and amylopectin structures. In this study, the polysaccharides are converted to glucose using alpha-amylase (α-amylase) and glucoamylase (GAmy) enzymes. The factors influencing the multienzyme catalysis, such as the substrate concentration, enzymes loading, pH and time, were varied to obtain the optimized condition for glucose production. The results of the glucose content using a microplate reader indicate that glucose was successfully produced via multienzyme catalysis. The oxidation of glucose employed in the EBFC was confirmed by the cyclic voltammogram (CV) analysis. The performance of EBFC was also assessed based on its maximum power density (MPD) and open circuit voltage (OCV) values. This multienzyme catalysis simplifies the multi-step process involved in converting polysaccharides to glucose.

Abstract (sommario):

Plant growth promoting rhizobacteria (PGPR) are strains of naturally occurring soil bacteria that live in close vicinity to the plant’s rhizosphere region which possess the capability to augment host growth. This study was conducted to isolate and identify potential PGPR isolates indigenous to Metroxylon sagu, Rottb. rhizosphere. These potential isolates were characterised based on their beneficial plant growth promoting (PGP) properties and identified by molecular analysis via 16S rDNA sequencing. A total of 18 isolates were successfully isolated, out of which five isolates were tested, and designated as (S1A, S2B, S3A, S3C and S42). Among the five isolates, two isolates (S2B and S3C) were found to produce high levels of indole-3-acetic acid (2.96 μg/mL and 10.31 μg/mL), able to fix nitrogen and show significant activity in phosphate solubilisation. The analysis of their sequences via National Center for Biotechnology Information (NCBI) suggested their close identity towards Lysinibacillus sphaericus and Bacillus thuringiensis. It can be concluded that the isolated PGPR possesses beneficial PGP attributes. It can be implied that the isolated PGPR are potential to be used as inoculant biofertilisers, beneficial for Metroxylon sagu, Rottb. growth. Hence, further studies need to be done to evaluate the effectiveness of the beneficial microbes towards sago seedlings growth, under pot experiment.

Abstract (sommario):

Pharmaceutical Grade Dextrose Monohydrate from Manihot ecsulenta, Metroxylon sagu, Zea mays, Oryza sativa, dan Triticum Starch ABSTRACT Pharmaceutical-grade dextrose monohydrate, one of raw materials used as active pharmaceutical ingredients (API) and additives, can be made from starch. There are five types of local Indonesian commercial starch that are potentially used, namely tapioca (Manihot esculenta), sago (Metroxylon sagu), corn (Zea mays), rice (Oryza sativa), and wheat (Triticum) starch. This study aimed to compare these five starches as raw materials for preparing pharmaceutical-grade dextrose monohydrate which was expected to meet the requirements of the Indonesian Pharmacopoeia (5th Edition) and the United States Pharmacopeia (USP). The starch was converted into dextrose monohydrate through liquefaction hydrolysis, saccharification hydrolysis, activated carbon purification and filtration, ion exchange purification, evaporation, crystallization and drying. High Performance Liquid Chromatogram (HPLC) and the Luff-Schoorl methods were used for dextrose equivalent value (DE) analysis. The results showed that only three of the starch types produced pharmaceutical-grade dextrose monohydrate, namely (DE) sago starch (107.23% and 100.77%), corn starch (97.86% and 96.19%), and tapioca starch (85.18% and 99.20%).Keywords: dextrose equivalent, dextrose monohydrate, hydrolysis, pharmaceutical grade, starchABSTRAKDekstrosa monohidrat kualitas farmasi, salah satu bahan baku yang digunakan sebagai active pharmaceutical ingredient (API) dan bahan tambahan, dapat dibuat dari bahan pati-patian.

Abstract (sommario):

<p>Indonesia’s dependency on fossil energy is relatively high; approximately 55 % fuel oil that comes from fossil is used in the household sector. The increasing of energy demand is not supported by the energy availability. This issue prompted the government of Indonesia to develop a diverse, cheaper, renewable, sustainable and eco-friendly alternative energy and to create an independent management which ensures the availability of energy to people in remote area. Among other possible solution, production of bioethanol from Metroxylon sago dregs as alternative energy resources is considered as the most feasible solution. Indonesia has ± 1,250,000 billion ha of sago plantation and in Papua there is ± 1,200,000 billion ha of land with sago potential, of which only 56 % is used. Research methods include fermentation of sago dregs to become bioethanol, its distillation process and flame characteristics. Results of laboratory experiment showed that sago dregs are viable as a source of fuel bioethanol because it still contains 82.4 % vol. of carbohydrate component. Measurement of flame temperature on bioethanol burner with ethanol content of 60 to 95 % is strongly influenced by these parameters: turbulence, temperature, mixing time and the rest of the air-fuel flow. </p><p><strong>Keywords</strong>: bioethanol; flame characteristics; Metroxylon sago dregs</p>

Abstract (sommario):

Among the significant problems in the sago processing, the extraction of the starch from its trunk tops the list. The extraction process involves a debarking and rasping process that is very tedious, unsanitary and time consuming that dramatically affects the quality of starch production since the local processor relies mainly on conventional method of extraction. This paper presents the design, fabrication and performance evaluation of sago pith extraction machine. The design concept made was to rasp the sago pith using a rotating rasper without debarking the log to minimize the steps on the extraction process. Four different teeth spacing of the rasper were considered during the testing and replicated three times; 1 cm, 2 cm, 3 cm, and no teeth as controlled parameters, respectively. Results revealed that teeth spacing has a significant effect on the performance of the machine such as extraction capacity, extraction efficiency and fineness of rasped pith. Based on average, the highest extraction capacity was recorded at 217.47 kg/h using 3 cm teeth spacing, and the highest extraction efficiency was 96.12% using 2 cm teeth spacing and the finest rasped pith having the lowest fineness modulus of 2.15 was when 1 cm teeth spacing is used. Compared to manual and other existing mechanical rasper accounting the process of debarking, machine’s extraction capacity is higher, more efficient, safer and hygienic. Cost and benefit analysis supports that the machine is profitable and the financial efficiency is high having a 65% rate of return and 1.8 years payback period.

Abstract (sommario):

Background: Sago (Metroxylon sp) is one of food commodities that contains many carbohydrates, so it serves as a staple food for some regions in Indonesia such as Maluku, Papua and Sulawesi. Sago can also be used as raw material for food industry such as bagea, sago pearl, pastry, wet cake, noodle, biscuit, cracker and vermicelli. Various uses of sago cause attention in terms of development and conservation. Saparua Island is one of the areas in the Maluku archipelago with sago potential that is wide enough. There are 5 types of sago in the area such as sago tuni, sagu molat, sago eataru, sagu ihur, and sago thorn rattan.Methods: This research took place in February-March 2014 by conducting exploration on location and samples selected by proposive sampling. For each quantitative parameter such as height, length, width, using a measuring instrument of ruler, roll meter while qualitative parameters such as shape, color can be observed visually.Results: Exploration was conducted on February-March 2014 with morphological character parameters on vegetative and generative organs of 70 characters. The results of the study showed a varied morphological appearance in each variety. Visually, variations of morphological characters in the vegetative organ seen in the trunk character are height, surface, circumference, color. Leaf character has variation in leaf sponge, leaf bone flexibility, midst of base of midrib, midrib, midrib, midrib, midlet, child length, upper surface. Morphological characters in generative organs appear to vary in flower, ie, the length and width of the stem, the diameter of the flower. Variations in fruits such as shape, amount, and color while on the seeds are the color and weight.Conclusion: There are variations of morphological characters in the five varieties of sago on Saparua Island in shape, size, and color, appearance of each organ either on stems, leaves, flowers, fruits and seeds.

Abstract (sommario):

A sago starch- based (Metroxylon sagu) edible coating with sago powder as a filler and glycerol as a plasticizer has been made.This research is expected to provide information about microbial sensitivity towards the sago starch- based edible coating which is eco-friendly and safe to be used. Requirements to determine food quality refers to the role of E.coli as a toxicity indicator to cause food damage. Toxicity testing of E. coli toward sago starch-based coating was conducted by using Kirby Bauer method. A standardized agar-disc paper diffusion procedure is one way to to determine antibiotic resistancy of bacteria. Bacterial resistancy toward antibiotics is determined by the diameter of inhibit zone formed. Microorganisms cultures requires media that contain nutrients and appropriate environment such as Nutrient Agar (NA). Based on E. coli toxicity testing conducted to the sago starch-based edible coating in 370C temperature and 48 hours of incubation, it is found that the edible coated has not anticeptic activity toward Escherichia coli because the inhibit zone is not formed on the sago starch- based coating. Therefore, the edible coating which has been made is healthy to be consumed.

Hal ini menunjukan bahwa adanya aktivitas antioksidan yang sangat lemah dari cendol Kappaphycus alvarezii yang diekstraksi. Kata Kunci : Aktivitas antioksidan, cendol, Kappaphycus alvarezii, Metroxylon sagus Rottb, fitokimia AbstractThe aims of this study was to determine the phytochemical content and antioxidant on cendol seaweed (Kappaphycus alvarezii) with additions of sago flour (Metroxylon sagus Rottb.) extracted with methanol. Phytochemical tests were performed to determine the presence of alkaloids, flavonoids, saponins, triterpenoids and steroids. Antioxidant activity of seaweed cendol. Kaphaphycus alvarezii was tested by DPPH method (1-1- diphenyl-2-picrylhydrazl). This study used a Completely Randomized Design (CRD) which consists of three treatments R1S1( RL 10% : TS 90% ), R2S2 (RL 20% : TS 80%), R3S3 ( RL 30% : TS : 70%) and three times replication. Observation data were analyzed using ANOVA (Analysis of Variance) at the level of 95%, if there were significant differences (P> 0.05) then further testing was carried out with DMRT (Duncan Multiple Range Test) at 95% significance level. Phytochemical test showed there was compounds detected with alkaloids, flavonoids, triterpenoids and steroids. While the saponins compounds was not detected in methanol extract of Kappahycus alvarezi. The antioxidant activity by DPPH method showed that the high IC50 values is 652 ppm. That was indicated seaweed cendol from kappaphycus alvarezii has lower antioxidant activity. Key words: Antioxidant activity, cendol, Kappaphycus alvarezii,Metroxylon sagus Rottb., phytochemical

Abstract (sommario):

The Borneo Island is the third-largest island and one of the greenest islands on earth. It is the natural habitat to various endemic flora and fauna such as the proboscis monkey (Nasalis larvatus), Malaysian mahseer (Tor tambroides), engkabang (Shorea macrophylla), Sarawak rasbora (Rasbora sarawakensis) and sago palm (Metroxylon sagu). In this mini review, we ventured into the current research, eco-economical aspects and potentials of each species and further provided future perspectives and recommendations to drive future research to greater heights besides supporting conservation endeavours.
