Fatty Acid Content of Indonesian Aquatic Microalgae
(2010)High utilization of fossil fuel increases the level of carbon dioxide in the atmosphere and results in global warming phenomenon. These things establish the world’s thought to look for the other alternative energy that can ... -
Fatty Acid Synthesis biy Indonesian Marine Diatom, Chaetoceros gracilis
(2009)Since the primary storage nutrients in diatoms consist of lipid, they are potential for the industrial fatty acid production. High value fatty acids include arachidonic acid, eicosapentaenoic acid and docosahexaenoic acid. ... -
Fecal Steroid Profile of Female Javan Gibbons (Hylobates moloch) Maintained in Pairing-Typed Cage
(2010)Estrone conjugate (E1C) and pregnanediol glucuronide (PdG) were predominant steroid metabolites of estrogen and progesterone in feces of most primates and could be used to evaluate ovarian function. These metabolites were ... -
Fecundity, Longevity, and Host Finding of Three Parasitoid Species of Liriomyza sativae
(2006)Liriomyza sativae is a polyphagous agromyzid leafminer and it has invaded large part of world, i.e Hemiptarsenus varicornis, Gronotoma micromorpha, and Opius dissitus. This research were conducted to investigate progeny, ... -
Feeding Rate of Soil Animals in Different Ecosystems in Pati, Indonesia
(2006)The feeding activity of soil animals was measured by using bait lamina test in three main ecosystems, i.e. the teak forest, home garden and rainfed paddy field. Two additional ecosystems in rainfed paddy field, i.e. the ... -
Flower Characteristic and the Yield of Jatropa (Jatropha curcas L.) Accessions
(2009)The flower characteristics of a plant is one of the important traits correlated to its productivity. Study on flower characteristics is useful to understand how to increase the crop productivity. The research was conducted ... -
Food Preference of Semi-Provisioned Macaques Based on Feeding Duration and Foraging Party Size
(2007)The long-tailed macaques (Macaca fascicularis; also called crab-eating monkeys) have broad geographic distribution in continent and archipelago of Southeast Asia. They have wide ecological plasticity to adapt to various ... -
Fractination and Characterization of Tannin Acyl Hydrolase from Aspergillus niger
(2009)We previously produced tannin acyl hydrolase (tannase) from Aspergillus niger isolated from cacao pod. In the present study the enzyme was subjected to fractionation by ammonium sulphate followed by dialysis process. The ... -
Functional Group of Spiders in Cultivated Landscape Dominated Dominated by Paddy Field in West Java, Indonesia
(2009)Distribution of spiders in all colonized environments is limited by biotic and abiotic factors requiring adaptations with respect to, for example microhabitat choice and hunting behavior. These two factors were frequently ... -
Functional Response of the Parasitoid Eriborus argenteopilosus (Cameron) to Crocidolomia pavonana (Fabricius) under Different Temperature
(2005)The functional response of the parasitoid Eriborus argenteopilosus (Cameron) (Hymenoptera: Ichneumonidae) were studied using Crocidolomia pavonana (Fabricius) (Lepidoptera: Pyralidae) larvae as host at different densities. ... -
Fungal Succession and Decomposition of Acacia mangium Leaf Litters in Helath and Ganoderma Attacked Standings
(2009)Leaf litters of Acacia mangium play an important functional role in ecosystem, producing sources of nutrients and giving diversity of microorganisms. Understanding the variation in fungal populations in A. mangium forest ... -
Genetic Differentiations among the Populations of Salvia japonica (Lamiaceae) and Its Related Species
(2008)Morphological and genetic variations within Salvia japonica (Lamiaceae) and its related species in Japan were analyzed for clarifying their taxonomic significance. The genetic variations were explored through chloroplast ... -
Genetic Diversity of Methylotrophic Bacteria from Human Mouth Based on Amplified Ribosomal DNA Restriction Analysis (ARDRA)
(2011)Methylotrophs inhabit the human mouth. In this study, methylotrophic bacteria were isolated from the human mouth microflora of 63 subjects, especially from the tongue, gingival, and subgingival area using minimal agar ... -
Genetic Parameter Estimation on Upland Rice Agronomic Characters in Ultisols through Diallel Analysis
(2005)An estimate of genetic parameters was made to study the types of gene action in rice. A half diallel analysis was performed among seven rice genotypes with different genetical backgrounds, i.e. Situgintung, Jatiluhur, Gajah ... -
