Selama ini pengelolaan sumberdaya alam hanya didasarkan pada pemenuhan aspek ekonomi serta hubungan yang bersifat fisik (physical interrelationship). Hal ini dapat diperhatikan adanya kecenderungan pengelolaan sumberdaya alam sebatas program konservasi lingkungan fisik seperti hutan, tanah, air dan bukan pengelolaan sumberdaya alam yang bertujuan untuk keberlanjutan sumberdaya alam (natural resources sustainability). Dengan demikian maka dapat dipastikan lambat laun atau cepat akan terjadi degradasi atau penurunan kualitas lingkungan yang pada akhirnya dapat menimbulkan bencana ekologis (Hadisusanto et al., 2003).

Industrial waste-water has become a serious problem nationwide. However, one type of waste-water, i.e. tofu waste-water (whey), can be utilized as the source of nata de soya production. This present research is attempts to reveal the effect of various concentrations of inocula and green-bean extracts on nata productions from tofu waste-water. Ten combinations of treatment were applied and coded as A1 â€“ A10. The parameters observed included physical and chemical characters of nata and nitrogen (N) contents. The results show that the increase in concentration of N and inocula will follow by the increase of water content, fiber content, plasticity, and N content of nata de soya produced. Highest thickness of nata was gained at 200 g/L concentration of green-bean extract and 100 ml/L concentration of inoculum.

Diversity of B. thuringiensis (Bt.) isolates pathogenic to C. binotalis was determined by using Numerical Systematic Method. Ten isolates were taken to represent 34 pathogenic isolates along with two reference strains namely B. thuringiensis serovar kurstaki and B. thuringiensis serovar israelensis. The test isolates were examined for 89 phenotypic characters by using convensional method for colonial and cell morphology (37 characters) as well as physiological characteristics (3 characters) but biochemical characterization (49 characters) was conducted by using commercial API-50 CHB procedures. All phenotypic characters existed in one of two mutually exclusive states and were either scored plus (1) of minus (0). The binary data were prepared in Programmerâ€™s File Editor (PFE) software. The data then were analysed by using the Multi Variate statistical Package (MVSP) Plus-Version 3.1 using the Simple Matching Coefficient (SSM). Clustering was achieved using the UPGMA algorithm. The results were presented as dendrograms. It was obtained that the test isolates were clearly assigned to two distinct multimembered clusters defined by 79.6 similarity level (S-level) in the SSM, UPGMA analysis. The two distinct clusters represented by each of two widely known different group of Bt. strains, namely serovar israelensis and serovar kurstaki. The first cluster contained reference strain of B. thuringiensis serovar israelensis, and two of the isolates (Slk2.3, and YPPA1) and the second cluster contained another reference strain of B. thuringiensis serovar kurstaki, and 8 of the isolates. Therefore, it strongly suggested that the application of numerical-fenetic analysis could provide a tool to unravel the strain diversity belong to B. thuringiensis.

A syntesis of pyrocathecol glucoside was carried out by applying biotransformation cell culture suspension from calus of Solanum mammosum L., on modified medium of Murashige and Skoog (MS). A growth maximum volume at 15,5 ml of cell culture suspension of S. mommosum was achieved on day-8 incubation. The results showed that pyrocathecol glucoside as a bitransformation product that was obtained by application of Pyrocathecol at 50-200 ppm was determined by TLC and identified at Rf value of 0.82?0.83. Futhermore, the biotransformation products were determined by HPLC obtained from the cell culture suspension at concentration of 200 ppm pyrocathecol so that resulted in reaction products based on standard solution. The peaks number 1, 2 and 3 with retention time 2.53 min, 4.62 min and 7.58 min were appropriate to the retention time cellobiose, glucose and methyl ?-glucoside, respectively. Peak number 4 with retention time 8.52 min conformed to pyrocathecol-glucobioside as a product of side transfer and peak number 5 with retention time 10.52 min in line with the retention time of arbutin were pyrocathecol-glucoside as a transfer product expected from the result of biotransformation.

Artemisia annua L. is a medicinal plant that has an antimalarial drug againts Plasmodium falciparum strains which are resistant to traditional drugs such as quinine and chloroquine. This plant contains artemisinin as major compounds found on its leaves. Aim of the research was to analyze the artemisinin content of shoot culture of A. annua which has five different in leaf morphologies (Morphology type A, B, C, D and E). Previous investigation showed that shoot regenerated from callus has five different morphologies. This somaclonal variation was permanent after continuously subcultured onto MS medium with no addition of plant growth regulators. Artemisinin was detected using HPLC and it was comfirmed by LC-MS. The results showed that shoot culture type B contained the highest artemisinin content (0.171%) amongst other type of morphology. Shoot type D showed the lowest level of artemisinin (0.006%) which was not significantly different with type E (0.008%). Addition of BAP at concentration of 1 and 2 mg/l increased artemisinin level of the shoot culturs.

The research was conducted in the Bawean island, East Java, where endemic Bawean deerâ€™s inhabited naturally. The objective was to assess what kind of plant species as food resources in natural habitat of Bawean deer. The most Bawean deer habitats particularly lowland forests, are under the greatest pressure. Logging and land conversion have caused dramatic decreases in the forest cover of Bawean island, mainly in lowland, and forest margins are progressively shifting towards higher elevations. In that conditions, therefore a management practices should be implemented soon, for improving deer habitat. This study was focused on availability of food resources in the natural habitat of Bawean deer. Using indirect methods in the field to assess the remaining of food resources, which was consumed by Bawean deer, and fecal analysis was executed for identifying food deer items. The result, there were many species of plants as a food resources including Imperata cylindrical (lalang), Pericampylus glaucus (ancucu), Caryota mitis (andudur), Discorea hispida (gadung), Symplocos adenophylla (kayu sape), Coelorhachis muricata (lampedung), Scheria hebecarpa (lanting-lantingan), Paspalum cunyugatum (lambu merah), Argyera mollis (rombok putih), Lygodium circinnatum (taliata), Nephrolepis hirsitula (rending-rendang), Tridax procumbens (kenci-kencian), Brachiaria distachya (kabak-kabakan alas), Frimbrisyllis dichotoma (lente-lentean). The availability of those food resources was affected by season i.e., dry and rainy season, and the feeding habit of Bawean deers can allow adapting to the habitat condition. Based on that figure the Bawean deers may have so many several of food items in their natural habitat.

The study of mammals visitation on salt licks in protected forest of Taratak, SoutheraCoast of West Sumatra was conducted from June to September 2005 (in total 6840hours.camera). Three camera traps were deployed separately on three salt lick areas.Nine species of mammals were recorded during the study. Tapirus indicus was thespecies most often photographed (13.5%), followed by Presbytis melalophos (11.3%) andSus scrofa (9.8%). This study also records the activity of human on salt licks areas. Thenumbers of visitation of mammals on three salt licks area differed, both in the numberof species and the number of individual. The differences of mammal visitation on saltlicks were not affected by size, altitude, and distances from village. The results alsoshowed that there was time segregation when entering the salt licks area, both interrestrial mammals and primates.
