The freshwater molluscs (snails and bivalves) can be found in many type of water course either flowing or stagnant water. Some of them have survived living in bad condition such as polluted water. There are 199 situ (small lakes) in Jabodetabek (Jakarta, Bogor, Depok, Tangerang, Bekasi) have been reported but only 20 % were in good condition, even 12% have dissapeared that caused by silting up of the situ. The aim of the study was to evaluate the diversity of the molluscs as well as to know the condition of on 36 situ along Ciliwung River and Cisadane River. Based on the collected samples, there were 13 species of snails and three species of bivalves. The freshwater snails Filopaludina javanica, Melanoides tuberculata, Pomacea canaliculata always occur in these situ but the bivalves Anodonta woodiana, Pilsbryoconcha exilis and Corbicula javanica only occur in situ Ciranji and Kemuning along Cisadane and Ciliwung rivers, respectively. The decreasing of the mollusc diversity was about 38% in Ciliwung River and 73% in Cisadane River, caused by polluted and silting up of the situ .

Kedawung is a member of the plant genus of Parkia (Mimosaceae). It has important value as traditional medicine and currently has been included in the Indonesian list of endangered medicinal plant species. There are two closely related species to Kedawung in Java: P. intermedia and P. speciosa. Parkia intermedia has long been assumed to be a hybrid between P. speciosa and P. timoriana. The species has leaflets linear-oblong and obtuse apex in mature foliage resemble P. speciosa, but has more numerous leaflets, linear-falcate, and acute apex in its juvenile leaflets similar to P. timoriana. Thus Hopkins (1992) included Petir as uncertain species. The aim of this study was to assess its current existing populations, to clarify the taxonomic status and to evaluate the similarity between kedawung and its related species. Exploration, morphology and leaf anatomical studies, as well as phenetic analysis have been conducted. The results indicated that morphology and leaf anatomical characters can be used to distinguish P. timoriana, P. intermedia and P. speciosa as different species, and P. intermedia was more closely related to P. speciosa than to P. timoriana.

Research at the three locations of Altingia excelsa Noronha plantations in Candikuning, Bali has been carried out to examine the changes in vegetation that grows naturally in the low layer after 22 years (1986 -2008). The results showed that 40 species of seedling, and 4 species of shrubs and young trees were found in three plots of the plantation forest. Compared to the results of the previous study, 22 years before the present study (1986), species richness was decreased dramatically accompanied by changes in species composition. Crown cover of herbs group were decreased, but shrubs and young trees were increased except for the plot 1938 due to edge effects. Lightdemanding species were disappeared and replaced by shaded-tolerant species. The primary tree species which are commonly found in the surrounding natural forest and previously found in research plots had been disappeared, and replaced by late secondary tree species, and seedlings of A. excelsa which is actually animmigrant species. Succession under the plantation forest of A. excelsa are generally slow.

Vaccination is one of the approaches against infectious diseases in cultured marine fish. The purpose of this study was to evaluate the effectiveness of Flexibacter vaccine in juvenile of tiger grouper (Epinephelus fuscoguttatus). Nine hundred of tiger grouper with total length of 7-8 cm reared in nine concrete tanks. For each three tanks, fishes were vaccinated with injection, immersion, and without vaccination as control. Booster was delivered at 10 and 30 days after first vaccination. Challenge test with live Flexibacter bacteria was performed 90 days post vaccination. Observations were made on clinical symptoms and survival rates which presented in relative percentage survival(RPS).The experiments were performed in completely randomized design with three replicates. The data then analyzed with ANOVA. The results showed that the antibody titer values of vaccinated fish were higher then unvaccinated fish, namely 128 for injection, 64 for bathing and 4 for control. Survival rates of vaccinated fish following challenged test were higher than control and significantly different (P<0.05), i.e. 88.67% (with RPS of 60%) for injection and 83.33% (with RPS of 50%) for immersion and 66.67% for controls. It is suggested that Flexibacter vaccine administered through injection and bathing are effective to increase immunity of tiger grouper against Flexibacter infection

Kentang hitam [Plectranthus rotundifolius (Poiret) Sprengel] of family Lamiaceae is a minor root crop known only for people living in some parts of Java, Bali and Madura. It was rarely found in its natural habitat, thus it was assumed to have low level of genetic diversity. This present study aimed to assess genetic diversity of 63 accessions of kentang hitam from provenances of Java based on Inter Simple Sequence Repeats (ISSR) and Random Amplified Polymorphic DNA (RAPD) fingerprints. Ten primers of ISSR and RAPD were initially screened and eight were selected for the analysis. These eight primers (OPA13, OPB10, OPB13, OPD8, OPN14, UBC 807, 834 and 835) generated 61 bands with an average of 7.63 polymorphic fragment per primer. Percentage of polymorphism ranged from 8.20% (UBC 807 and 834) to 16.39% (OPB 10) with an average of 12.50%polymorphism.Clustering analysis was performed based on ISSR and RAPD profiles using the neighbour joining method and Principle Coordinate Analysis (PCO). The range of genetic similarity among accessions was 51-100% to which most of the accessions were clustered with more than 80% similarity. This confirmed our hypothesis of the low level of variation existed among accessions.

The development of seedless tomato fruits will be more attractive to consumers and industry. Artificial parthenocarpy can be induced through genetic crossing, hormone application or genetic engineering. Development of parthenocarpic tomatos has been done by inserting parthenocarpy gene, DefH9-iaaM into tomato genome via Agrobacterium tumefaciens. Sixty putative transgenic tomato lines were produced, and three events (lines) have been selected as the best event, i.e. OvR1#14-4, OvM2#10-1, OvM2#6-2. These lines contained the DefH9-iaaM based on PCR test. This research aimed was to determine the insertion patern of DefH9-iaaM gene in the progeny of transgenic tomatos lines. Parent variety Oval and line Cl 6046 were used as control plants. Results indicated that tomatos line OvR1#14-4 was still contained the inserted DefH9-iaaM gene and followed the Mendelian pattern (3:1) based on molecular analyses and Chi-square test results, while the others were not identified. Line OvR1#14-4 was required to be further evaluated for phenotypic and genotypic analyses for the expression of their parthenocarpy.

White shells Meretrix meretrix is one of the bivalves that are often sold in local markets of Makassar. Meretrix meretrix is one type of shellfishes that is favoured by the people so that they are continuedly being taken from their habitat without considering the feasibility of the capture. This research was aimed to determine the correlation between shell length, shell width, shell thickness, and total weight of the meat as well as assessing the size of a decent catch of M. meretrix in Makassar. Morphometric relationship between the length, width and thickness of the shell and total weight of the meat was analyzed using regression analysis.The results showed that the length and width of the shell and the length and total weight had strong positive correlation (0.81 = r = 0.96 and 0.81 = r = 0,92 repectively).The lenght and thickness of shell was moderately correlated (0.57 = r = 0.76), while the length and weight of the meat showed weak correlation (0.02 = r = 0.47). Size of M. meretrix sold in TPI Rajawali, Sentral market and Tanjung market ranged between 2.00 ? 6.99 cm and has fulfilled the catching standard, which is > 4 cm.

Hybridization is one alternative of genetic improvement to increase the production of commercialize commodity. The aim of this study was to determine the character of reproductive performance and the value of heterosis from cross-breeding of giant gouramy (Osphronemus gouramy) strain Bastar and Bluesafir. Crosses were performed in both directions (reciprocal) with naturally spawning system. Two pairs of giant gouramy of each strain were used, each pair contained 4 ? and 1 ?. Every pairs were reared in 3 x 3 m of pond.Reproductive characterization, such as Fecundity, Ovo Somatic Index, egg diameter, egg weight, Fertilization Rate (FR), Hatching Rate (HR), the latency time of hatching, and yolk sack absorbtion period, were observed. Other parameters including larval lenght and Survival Rate (SR) were also observed. Heterosis (H) value was calculated from FR, HR and SR. Result showed that each population and its cross-breed had no different in reproductive characters. Latency time of hatching, egg diameter, egg weight and yolk sac absorbtion period values were 3 ± 0 days; 0.74 ± 0.05 cm; 11 ± 4 mg dan 9 ± 1 days, respectively. Meanwhile fecundity value showed that Blusafir strain had higher fecundity (3661 ± 624), and Ovo Somatic Index percentage (21.96 ± 3.74). The highest HR was presented by ? Bluesafir x ? Bastar (97.95 ± 0.47 %), meanwhile ? Bastar x ? Bluesafir presented the highest FR and SR (99.15 ± 0.34 % and 92.57 ± 0.40 %). Heterosis value showed that cross-breeding between ? Bastar x ? Bluesafir had better HR and SR (1.20 and 2.37), white hand cross-breeding between ? Bluesafir x ? Bastar presented better FR (0.69).
