Abstract

Rattan plays an important role as food resources in the culture of the Dayak communities living near forest areas. Shoot of rattan is cooked by the Dayaks to make a dish "sayur umbut rotan". This stir-fried rattan shoot cuisine is always served in the event of Dayak traditional ceremonies. The aim of this study was to identify and inventory of rattan species that uses in the Dayak food. The study was carried out at the villages of Mantangai Hulu, Kalumpang, Katimpun, Sei Ahaz and Katunjung, in the Kapuas District, Central Kalimantan Province. The method used ware interviewing local community, making field observation and collecting voucher specimen of rattan for identification in the Herbarium of Center for Conservation and Rehabilitation Research and Development. Result of the study was revealed that six species of rattan were used in the Dayak foods which are Calamus caesius Blume, C. trachycoleus Beccari, C. ornatus Blume ex Schult. & Schult.), Daemonorops crinita Blume, D. fissa Blume, and Plectocomiopsis geminiflora (Griff.) Beccari. It is recommended that these six species of rattan should be cultivated in their garden to lessen disturbance to the natural population. Key words: Dayak; local communities; rattan; traditional food

Abstract

Biomolecular systems and cellular capabilities can be engineered by synthetic biology. One of its wide applications is for bio-control. Several teams competing in the International Genetically Engineered Machine (iGEM) competition have utilized the potency of synthetic biology for pest control. Some of their ideas are highlighted in this review. Taking advantages from Indonesia’s rich biodiversity, those ideas can be expanded. Bio-control using E. coli expressing pheromone biosynthesis activating neuropeptide (PBAN) from rice yellow stem borer (Scirpophaga incertulas) can be used to control that pest. The adapted ideas can serve as starting points for research and implementation of bio-control in Indonesia.Keywords: Bio-control, biodiversity, iGEM, Indonesia, synthetic biology

Abstract

Antioxidant is a substance that inhibits oxidation or reactions promoted by oxygen, peroxides, or free radicals. Antioxidants are also commonly added to food products such as vegetable oils and prepared foods to prevent or delay their deterioration from the action of air. Antioxidants may possibly reduce the risks of cancer.  This study aimed to determine the antioxidant activities of rhizome of Laja Gowah (Alpinia malaccensis (Burm, F.) Roxb.) by using DPPH (1,1-Diphenyl-2-Picrylhydrazyl) methods. Laja Gowah (Alpinia malaccensis (Burm, F.) Roxb. ) is classified into family of Zingiberaceae. Extraction is done by maceration with methanol solvent and fractionation by using a funnel with a solvent which has different levels of polarity, namely the n-hexane and ethyl acetate. Qualitative analysis is measured by thin layer chromatography for fraction methanol, n-hexane and ethyl acetate. All fraction showed the presence of flavonoids and terpenoids which is marked by appearing yellow and purple spots after reacting by H2SO4 10%. Determination of antioxidant activities from the each fraction showed that all fractions have potential function as an antioxidant with LC50 values. Fraction of n-hexane showed 72.03 ppm, fraction of ethyl acetate showed 96.31 ppm, and fraction of methanol showed 194.43 ppm. For comparison, ascorbic acid has antioxidant activities with IC50 values as many as 2.23 ppm.Keywords: Alpinia malaccensis; antioxidant; 1,1-diphenyl-2-picrylhydrazyl

Abstract

Dipeptidyl Peptidase-4 is a epithelial transmembrane protein of many cell type such as gastrointestinal tract, biliary tract, pancreas, kidney, thymus, uterus, prostate and capillary endothelial cell. It has a cytoplasmic domain (amino acids 1-6), transmembrane domain  (amino acid 7-28) and extracellular domain (amino acids 29-766). Dipeptidyl Peptidase-4 also found in soluble form of serum and other body fluid. Soluble DPP-4 has not a cytoplasmic domain and transmembrane domain. The level of soluble dipeptidyl peptidase-4 increased in diabetes. In diabetes, Hydrogen Peroxide as Reactive Oxygen Species (ROS) involved in transmembrane DPP-4 shedding to produce soluble DPP-4. Hydrogen peroxide can be converted into hydroxyl radicals (•OH) which are highly reactive. Hydroxyl radicals can oxidize  fatty acid such as linoleic acid which is found mainly in Low Density Lipoprotein (LDL). This study was aimed to elucidate the molecular mechanism of oxidation to shed  transmembrane DPP-4 to produce soluble DPP-4. The DPP-4 model used is DPP-4 with 10-766 amino acid derived from Uniprot and 3D Jigsaw program. Oxidized linoleic acids were derived from NCBI pubchem. DPP-4 as a receptor was docked with oxidized linoleic acids as ligand by patchdock program. And the result show that 13-HODE more easily interact acid with DPP-4than  the other oxidized linoleic. That  oxidants had the active site on DPP-4 (Threonine 36 and Alanine 37) that allow the shedding of transmembrane DPP-4 to produce soluble DPP-4. But that oxidant also interact with the other  site  of DPP-4 that may destroy the catalytic domain.Keywords: DPP-4; oxidized linoleic acid; shedding

Abstract

This research was conducted in order to determine the teacher’s competencies on management of science laboratory based on Permendiknas no. 26/2008 in Pekanbaru City for academic year 2014/2015. Subjects in this study are science teachers who manage science laboratories of secondary schools in Pekanbaru City. The numbers of subjects are 29 people from Public Secondary School in Pekanbaru City. Collecting data in this study was conducted by questionnaire, interview, and observation (The data analyzed descriptively and the unit measurement on analysis technique that used in this study is percentage.) From the research, its known that personal competence categorized as very competent  with percentage of 91.01%. Social competence is 89.90% categorized as very competent. Competence of administration is 86.74%. Then the professional competence 86.64% categorized as very competent. Competence managerial categorized as very competent (86%). It can be concluded that level of competence in management of the science lab teachers at Pekanbaru’s Public Secondary Schools for Academic Year 2014/2015 are very competent.Keywords: Management of science laboratory; public secondary school; teacher competencies
