EFEKTIVITAS EKSTRAK BIJI PICUNG (Pangium edule Reinw.) TERHADAP MORTALITAS KEONG MAS (Pomacea canaliculate Lamck.)

This research attempted to substitute commercial with botanical molluscicide i.e. picung (Pangium edule) seed. The trial of picung seed water extract (PWE) was conducted in 3 groups of gold apple snails (Pomacea canaliculata) - (GAS).Group 1 with body weight (bw) was 4 to 5 grams, Group 2 was 10 to 12 grams and Group 3 was blank. Both group (1 and 2) were soaked in 4 regimes of cyanide concentration from PWE: 100, 50, 25 and 12.5 /tg/mi and put 10 snails for each concentration. The observation on their mortality was conducted for 24 hours. The result showed that PWE killed 100% of GAS (< 1 hour) with concentration in 50 µg/ml and 25 µ g/ml cyanide in Group 1 and Group 2, respectively, with clinical sign is the production of excessive mucous as criteria of molluscicide effect thus picung seed is quite significant as botanical molluscicide

Genus Diversity of Actinomycetes in Cibinong Science Center, West Java, Indonesia

Actinomycetes are microorganisms that play important role to support human health and  known as soil microorganisms. The aim of the research was to describe genus diversity of actinomycetes in Cibinong Science Center (CSC), West Java. Samples for isolation were soil and plant litters. The samples were air dried and ground. We employed isolation methods: dry heat (DH), sodium dodecyl sulphates-yeast extract (SDS-YE), rehydration and centrifugation (RC), and oil separation (OS). A total of 263 isolates of actinomycetes were isolated in CSC, in 2004-2006. Totally 58, 144, 50, and 11 isolates were isolated under each isolation methods, respectively. All isolates were identified using the 16S rRNA gene sequencing method. The results showed that the isolates were belonged to the family Kineosporiaceae, Micromonosporaceae, Nocardiaceae, Pseudonocardiaceae, Streptomycetaceae, Streptosporangiaceae, Mycobacteriaceae, Nocardioidaceae, Nocardiopsaceae, and Thermomonosporaceae. There were 23 genera under those families. Homology value of the isolates based on BLAST search using 16S rRNA gene sequence data as queries showed that 136, 91, 30, and 6 isolates were ≥99, 98, 97, and ≤96%, respectively, compared to the known sequence in data base. The later 6 isolates were interesting for further identification leading to new taxa. Recognized species of Streptomyces genera under the member of the Streptomycetaceae were dominant among other isolates
