One of the greatest affected factors toward the growth of V. radiata is considered as the availability of water. Obviously, less production of V. radiata is due to short water supply. This research shows that flower initiation, flowering and fruiting to reproduction of four V. radiata varieties (Belu, Kenari, Perkutut and Murai), affected by drought are taken under this investigation. Based on numbers of initiated pod flowers and pods being produced, the most sensitive reproduction stages to drought in Belu variety were flower initiation and flowering, Kenari variety were flowering, Murai variety were flowering and fruiting, and Perkutut variety in all reproduction stages posses relatively similar level of sensitivity to drought. Generally, number of flowers initiated pods and the number of pods produced were higher in Kenari and Murai varieties compared to those on Perkutut and Belu. Based on numbers of flowers initiated pods and numbers of pods production, drought at flower initiation and flowering stage were more highly affected on Belu and Perkutut varieties compared to that of Kenari and Murai. Droughts on fruiting stage are highly affected on Perkutut varieties as well compared to other varieties. Therefore, based on plants production and their tolerance to drought, the best plants to be cultivated are Kenari and Murai.

Kaempferia rotunda, usually called as temu putih is belonging into Zingiberaceae family.This plant has been used as traditional medicine for curing diarrhoe and disentry.Objective of the study was to determine the effect of pseudo tubers number and organicfertilizers on the productivity of K. rotunda. Research was conducted in TreubLaboratory, Research Centre for Biology LIPI, Bogor, from July 2002 until April 2003.The experiment was arranged in a factorial Randomized Block Design. The treatmentsconsisted of two factors, i.e the first factor were number of pseudo tubers (0, 2 and 4)and second factor were organic fertilizers (soil, goat manure and compost).The result of the exsperiment showed that both factors, i.e number of pseudo tubers andorganik fertilizers significantly affect productivity of K.rotunda. The effect of goatmanure more dominant than compost. The interaction of those two factors significantlyinfluenced number of leaves and fresh weight of rhizome. The best results was on thecombination treatment of two pseudo tubers and goat manure which had the highestvalue on all peubahs observed which were increased growth and yield of K. rotundasignificantly.

Caulerpa racemosa is a green benthic macroalga that mainly grows in tropical regions which is expected to bask of strong ultraviolet radiation from sunlight. This circumstance can cause to increase levels of reactive radical species. To reduce and/or protect, organism like macroalga may change its metabolism and stimulate to produce some active compounds, therefore, tropical macroalgae are estimated possessing a large number of active compounds such as antioxidant. In this experiment, edible green benthic macroalga Caulerpa racemosa grown in different water condition were used. The content of total phenol and antioxidant activity of ethyl acetate extract were performed. Pearson correlation between waters condition and antioxidant activities i.e. total phenol and DPPH inhibition were also analyzed. Caulerpa racemosa grown in station 2, exposed in strong radiation from sunlight, had the highest content of total phenol and percentage of DPPH inhibition, with their values were 12.60% and 46.43% respectively. Sunlight intencity in waters had strong positive correlation to the total phenol content and reducing activity of DPPH, however, parameters of nitrate and ammonia had strong negative correlation.

The whole nine isolates of endophytic fungi have been obtained from leaves and roots of pandan wangi (Pandanus amarylifolius) collected from Bogor Botanical Garden. Identification of the fungi isolates were conducted based on their morphological characteristics, and revealed that one fungus belongs to the genus of Fusarium, one of Dreschlera, and 7 fungi isolates belong to Coelomycetes. The ethyl acetate extract of the fungi cultures in PDB and GYP media showed a diverse secondary metabolite profiles. Ethyl acetate extract derived from the culture of PWA-2 fungus in GYP medium showed an antifungal activity against Saccharomyces cerevisiae, but not to Fusarium oxysporum and Candida tropicalis. The GC-MS analysis of the active extract showed eugenol as an active component.

Soil pollution by substances such as benzene can cause serious problems such as aquifer contamination and reduction of the biodiversity of organisms. A number of microorganisms are capable to degrade such substances naturally. However, introduction of any other microorganisms and or nutrient (bioaugmentation) are necessary in order to improve the biodegradation rate. This study examined the effect of introducing promising local strains of Bacillus namely U41 and U44, and urea addition at concentration 0.25% w/v. The parameter measured was benzene, pH, microbial number, and CO2. The best result was revealed from bioaugmentation of mixture of U41 and U 44. However, that result was not significantly difference with the use of single either strain U41 or U44, respectively.

Information on ability of Aspergillus niger to secrete organic acid is important in using A. niger as phosphate rock-solubilizing microorganism. This research was aimed to examine the ability of A. niger YD 17 secreting organic acid when it was grown with phosphate rock. An A. niger YD 17 was obtained from Laboratory of Microbiology, Faculty of Agriculture, GMU. The phosphate rock used was Christmas Island phosphate rock. Organic materials consisted of tapioca waste industry, rice bran, and starch. The study was conducted in Pikovskaya liquid medium and soils that were taken from Jasinga, Banten, West Java (ultisol) and Karang Jati, Ungaran, Central Java (inceptisol). The type and level of organic acid production were determined using high performance liquid chromatography (HPLC). The results indicated that A. niger YD 17 was able to secrete organic acid when it was grown with phosphate rock. The level of organic acid in the Pikovskaya liquid medium reached 255.7 ïg.ml-1, whereas in the soil reached 2992.5 ïg.g-1. Malate dominated organic acid in the Pikovskaya liquid medium, while in the soils dominated by oxalate. The type and level of organic acid secreted by A. niger YD 17 were influenced by carbon and phosphorus sources, concentration of inoculums, and characteristic of the soils.

The study about fruiting and flowering phenologies on various tuber weights of iles-iles has not been common yet. The fact was emphasized by Lingga et al. (1989) that most biologists and agronomists are not interested in doing research about the iles-iles, so the source is not easy to get. This research was aimed to studying the fruiting and flowering phenologies on various tuber weights of Iles-iles (Amorphophallus muelleri Blume). The experiment was done at Bogor Agricultural Institute experimental field, Darmaga at 250 m sea level height, from February 2000 to August 2002. The experimental design used was Completely Randomized Block Design with six replications. The treatment consist of four level of tuber weights, A = more than 1050 g; B = more than 700-1050 g; C = more than 350-700 g; D = less than or same as 350 g. The results showed that flowering of iles-iles occur on rainy season, after high rain intensity everydays. The higher tuber weights, compared with smaller tuber weights, produce bigger percentage of flower sprout, size of flower parts, flower size and fruit amount, and also total amount of embryo per stem. On the contrary, the percentage of vegetative sprout was produced more by lighter tuber. The flowering and fruiting on iles-iles, seem influenced by the interaction between tuber weight and the growth age of tuber.

significant contribution to those who living in and around mangrove forests. Like any othercommunities who occupied areas surrounding forest sites, Papuan ethnic groups really connectand integrate with the forest environment such as mangrove forests. This paper is a review ofrelated literatures that compiled from different research which have been conducted inUniversitas Negeri Papua (UNIPA) on utilization of mangrove by local ethnic groups and its rolefor other life biota in Papua. The results indicated that mangrove plays a very important rolefor local tribes in Papua as food sources, construction materials and source of energy,traditional medicine sources and wildlife habitat that are usually consumed by the communities.Ecology-based tourism or ecotourism as one leading sector of mangrove forests in Papua,though has a good potential, has not been optimizedly used.

A field research was conducted in Ujung Kulon National Park (TNUK) to reveal the biodiversity of Gastropoda which live associated with mangrove ecosystem. As many as 793 specimens were collected and identified. These specimen consisted of 14 families, 27 genera and 59 species which could be classified into: Native molluscs (37 species, 62.71%), Facultative molluscs (5 species, 8.47%) and Visitor mollusks (17 species, 28.81%). Within Native molluscs, 19 (51.35%) from 37 species were confirmed as new records from TNUK since they had not been recorded before. One family of Facultative molluscs, the Onchidiidae (Onchidium chameleon, O. damelli dan O. patelloides) was confirmed as new record from mangrove of Java. Totally from 59 species found here, 33 species (55.95%) were confirmed as new records, the other 26 species had already been recorded by TNUK. Some interactions (predation, mating and aggregation) among individuals were also observed in the field.
