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.

The research was conducted to explore protein and isoflavone content on soy non germed and soy germed. Soybean ?slamet? was rinsed, dipped over night, drained, put in a moist room, and water sprinkled once in a while until germed. The husk of soy and soy germ were removed, and then the soy and soy germ were extracted by NaCl physiologic to become slurry. The slurry pH was arranged to 5.0, centrifugated at 10.000 rpm, and the precipitation was dryed in 70oC to obtain the soy protein and the soy germ protein flour. The levels of protein and isoflavone flour were determined. The result showed that protein content of soy was 36.5%, while protein of soy germ was 42%. The isoflavone of soy protein was 26.7 ppm, consisting of 11.5 ppm genistein, 10.2 ppm daidzein and 5 ppm glicitein, but the soy germ protein was 39.1 ppm, consisting of 14.6 ppm genistein, 16.9 ppm daidzein and 7.6 ppm glicitein. The conclusion is that germed process could increase protein and isoflavone content. The soy protein isoflavone was dominated by genistein and daidzein, while soy germ protein isoflavone was dominated by daidzein and glicitein.

A study of Agamid lizards diversity and their distribution surrounding Martabe Mining project Area, South Tapanuli, North Sumatera was conducted in five different habitat types. The data were gathered by opportunistic searching in each habitat type with two replications. Shannon-Wiener index was used to determine the diversity while the homogeneity was verified by Pielou index. The similarity of Agamid communities among habitat types was confirmed by Sorensen coefficient. As a result, 9 Agamid species were recorded with Draco melanopogon as the major component of Agamid community making up 49.1% of total individuals gathered. Highest diversity occurred in moderately disturbed forest, but the most homogeny took place in riparian lowland forest. The cluster analysis using Sorensenâ€™s coefficient of agamid species distribution among habitat types distributed the habitats into three major groups, with the most similarity occurred between primary and riparian lowland forests (75%). The identification key of the species was made.

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.
