Abstract

This study was conducted to examine the effect of “keben” seed Baringtonia asiatica (L.) Kurz on mortality of flea (Coccus viridis) found in Coffea sp. Experimental methods with Complete Random Design (CRD) was used in this study. Five doses of “keben” seed extract (0.2%, 0.4%, 0.6% 0.8% and 0.0%) were used. Result of the study showed that all five concentration of “keben” extract were toxic to Coccus viridis, therefore can be used to control pest of coffe caused by Coccus viridis. Among the concentration used, it was found that concentration at 0.4% more effective than other concentrations. Consentration at 0.4% was killed 100% of Coccus viridis population in 3 days.Key words: Barringtonia asiatica, Coccus viridis, Concentration of seed extract.

Abstract

Dalam penentuan kesuburan suatu perairan, plankton mempunyai peranan penting. Hal ini disebabkan karena plankton merupakan produsen yang mampu melakukan fotosintesis. Plankton mempunyai peranan penting dalam sistem rantai makanan di kawasan perairan, baik di laut, perairan air tawar maupun payau. Sehubungan dengan hal tersebut telah dilakukan penelitian tentang keragaman jenis plankton di perairan laut di Kota Jayapura. Metode yang digunakan adalah survey, dengan pengambilan sampel pada tiga (3) lokasi yang berbeda, yakni di Pantai Dok II, Pantai Hamadi, dan Pantai Skow Mabo. Hasil penelitian menunjukkan bahwa di Kota Jayapura, khususnya di stasiun penelitian Pantai Dok II, Pantai Hamadi, dan Pantai Skow dijumpai 52 jenis plankton. Dari 52 jenis tersebut satu (1) diantaranya belum dapat teridentifikasi, yakni dari jenis fitoplankton. Di Pantai Dok II, dijumpai 25 jenis, pantai Hamadi terbanyak yakni 32 jenis, dan Pantai Skow hanya 16 jenis. Jenis–jenis plankton di lokasi ini menunjukkan tingkat kesuburan perairan pantai. Pantai Hamadi tergolong jenisnya sangat beragam, sedangkan pantai Skow tidak mempunyai keragaman yang tinggi.Key words: Keragaman plankton, Pantai Dok II, Pantai Hamadi, Pantai Skow, Jayapura.

Abstract

Papua is well known asa megabiodiversity area because it has high diverse biological resources; on the other hand the diversity of plankton biota has not been much studied. Plankton has an important role in the food chain system in the waters, both at sea, freshwater and brackish. The purpose of this study was to determine the level of marine water fertility based on the presence of plankton diversity in the Kepala Burung, West Papua Province. The method used was a survey, with sampling at six (6) point coordinates in Manokwari and Sorong regency. The results showed that there were 66 types of plankton found in marine waters Manokwari and Sorong, Kepala Burung region, West Papua Province. Therefore these waters are still quite fertile with diversity index (H') in Manokwari was 2.80 (32 types of plankton), whereas in Sorong 3.16 (48 species).Key words: plankton, water fertility, Manokwari, Sorong, West Papua Province.

Abstract

Study of isolate characterization of Bacillus thuringiensis Berliner collected from soil was done at UNCEN Campus. The aims of the study were to explore the local isolate of B. thuringiensis and to study the toxicity of the isolates on larvae of Anopheles as a vector of malaria and filariasis deseases in Papua. Data was analized by Hadioetomo & Rusmana method (1977). The results showed that 383 colonies are relatively closed to B. thuringiensis whereas 290 of them are indicated as local isolates of B. thuringiensis. Based on toxicity detection on larvae of Anopheles found that 19 isolates have toxicities levels 50% or more. Among the 19 isolates 3 of them has 80%, 85% and 90% toxicity levels separately.Key words: Characterization, local isolate, B. thuringiensis, toxicity, and soil.

Abstract

The aim of this study was to observe the presence of coliform bacteria and the level of contamination in outlet water of Sentani lake, especially in Jaifuri river. The study was done from Januari-April 2009 in 3 sampling areas: outlet of the lake (A), in between outlet and the river (B), and in Jaifuri river (C). Samples then be analized in Biology Laboratory, FMIPA University of Cenderawasih using MPN (Most Probable Number) series 3-3-3. Furthermore, the result then compared with the quality standard of dringking water (Peraturan Menteri Kesehatan RI No 416/MENKES/PER/IX1990). The result showed that coliform of sample A was 9.300 MPN/ 100 ml, sample B was 4.300 MPN/100 ml and sample C was 24.000 MPN/ 100 ml. That condition was above the maximum level of contamination of dringking water (0/100 ml). In addition, the biochemical test showed that Escherichia coli and Klebsiella pneumoniae were found in that water samples.  Key words: Coliform, Escherichia coli, outlet of Sentani lake, Jaifuri river, East Sentani.
