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

Papua is an area with very wide range, from lowland with altitude 0 m to highland area with 4730 m above sea level. Orchids species constitute the greater part of orchids diversity, which can grow on the bare branches of tall trees, or embedded in moss dripping in wet and cool mountain forests, as well as in the eternal shade of tropical rain forest. Numerous plants world-wide are threatened with extinction because of degradation or destruction of their habitat. Orchids are among the most threatened plants of all, especially when pressure from dealers and collectors aggravales the problems. South Papua is a lowland area with the elevation around 0-7 m above sea level, temperature 23-300 C, and 1500 m rainfall per year. The aims of these investigations were to explore the diversity of tropical orchids in South Papua. The exploration and collection were done in Asmat, Boven Digul, Mappi, and Merauke. The study found 22 genera and 75 species, mostly are epiphytic.Key words: orchids, exploration, diversity, South Papua.

Abstract

Endomycorrhiza palys important role in nutrient uptake of agricultural plant. The purpose of this study was to investigate the presence of endomycorrhiza associated with non-legume plants, i.e.:Zea mays L., Solanum lycopersicum L., Capsicum frutescens L., Brassica oleracea L. and Brassica juncea (L.) Czern,  in agricultural area in Koya Barat, Jayapura. Survey was done before collecting root and soil samples. The root of those non-legume plants were cleaned and stained using method developed by Kormanic and Mc.Graw. Wet seaving method was done to analyze soil samples. The result showed that those non-legume plants were infected by endomycorrhiza. The highest infection percentage was on corn (Zea mays L.), while the lowest was on cabbage (Brassica oleracea L.). Furthermore, from spore identification, 14 species of endomycorrhiza were found on the rhizosphere of those plants which were grouped into genus Glomus (5 species), Gigaspora (2 species), Acaulospora (2 species) and Scutelospora (1), however 4 species were remain unidentified yet. Therefore further study should be done to elucidate this problem.Key words: endomycorhiza, exploration, non-legum, Koya Barat, 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 ecology of mangrove organisms at Yotefa Bay Jayapura has been done from February to December 2012. The main purpose of this study is to collect the ecological data mangrove organism focus on diversity, distribution, richness, and similarity. The study was on organisms which have economical values for people living at the Papua Trade Centre area (PTC), Skyland, and Nafri. The data were collected with the line transects and quadrate methods, and data was examined with description on quantitative and qualitative methods. The result showed that there were 7 species of mangrove organism which have economical values; which were Anadara granosa, Anadara pilula, Isognomon ephippium, Gelonia erosa, Gelonia expansa, Pinna nobilis, and Faunus ater. The diversity index revealed that the highest number of species diversity was in PTC and Nafri area which were 1,70  and the lowest species diversity was in Skyland area which was 1, 55. The highest species evenness (E) was occurred in skyland and Nafri,  which was 0,80 and the lowest was in PTC which was  about 0,32. The highest abundance of species occurred in Skyland area was G. expansa scoring 4,9 ind/m2 and the lowest  abundance in Nafri was P. nobilis scoring 1 ind/m2. The similarity index for the PTC Area, Skyland, and Nafri was on spesies of G. erosa, G. expansa, A. granosa, I. ephipium, and  F. ater.  Key words: Mollusca, mangrove, Youtefa bay, and Jayapura.

Abstract

The study about the activity of the enzyme amylase from amylolytic bacterial isolates from wet sagoo starch and  its traditional provision environment had been done in Jayapura. The purposes of this study were to determine the activity of amylase enzyme and to identify the bacteria isolated from wet sagoo starch and its processing environment in Jayapura district. The method used was an experimental laboratorium in which isolation of amylolytic bacteria was performed by using nutrient agar medium with 1% soluble starch on spreed pour plate method. The enzyme activity was detected with 0.2% iodine in 2% potassium iodide which were able to form a clear zone. The protein content of the crude enzyme extract was determined by the Bradford method using bovine serum albumin (BSA). Amylase enzyme activity was determined by the formula: DUN/ml = [(R0-R1)/R0] [dilution factor] DUN/ml (dextrinizing units per ml). The results showed that there were 15 isolates amylolytic bacteria. Four (4) bacterial isolates have amylolytic power of more than 30 mm. The amilase activity of amylolytic bacterial of all  isolates were quite high: which were 35 577, 18 903,  32 106 and 46 600 U/mg for SU4, SU13, SU23 and SU40 respectively. The identification of isolates indicated that the three isolates are members of the Bacillus cereus ATCC 14 579 types with a similarity value of 71.70% to 81.10%, and one isolate is Bacillus subtilis ATCC 6501 members with a similarity value of 94.30%.Keywords: Amylolytic bacteria, amylase activity, characterization, sago flour.

Abstract

Protein merupakan salah satu makronutrien penting bagi tubuh. Fungsinya sebagai zat pembangun dan memelihara sel-sel dan jaringan tubuh, menyebabkan kekurangan protein akan berakibat serius bagi kesehatan. Salah satu alternatif pemenuhan kebutuhan protein adalah dengan pemanfaatan bahan pangan lokal. Ulat sagu (Rhynchophorus papuanus) telah lama dikonsumsi oleh masyarakat asli Papua dan Maluku sebagai pelengkap (lauk) bubur sagu (papeda) dan diketahui dari kandungan zat gizinya dapat berperan sebagai sumber protein. Penelitian ini bertujuan mengetahui kualitas protein ulat sagu (Rhynchophorus papuanus). Ulat sagu dikembangbiakkan pada media batang sagu dengan tiga varietas sagu masing-masing adalah Debet Embyam, Kutu blup, dan Kutu Mamakutu (berdasarkan pengetahuan indigineus etnik Moy). Dilakukan analisis kimiawi untuk mengetahui kadar protein, lemak, air, dan abu. Sedangkan kualitas protein ulat sagu ditentukan dengan penentuan NPR (net protein ratio) dan penentuan nilai kimia asam amino. Hasil penelitian menunjukkan bahwa ulat sagu mengadung protein dengan kualitas cukup baik, yang diperlihatkan dengan nilai kimia asam amino ulat sagu, masing-masing yang dikembangbiakkan pada Debet Embyam = 97,54%; Kutu blup = 80,77%; dan Kutu Mamakutu = 77,53% dengan asam amino pembatas metionin. Sedangkan nilai NPRnya masing-masing 3,31; 3,16; dan 3,17. Tidak ada perbedaan yang signifikan terhadap nilai NPR ketiga perlakuan tersebut.Key words: Kualitas protein, ulat sagu, Maribu, Jayapura
