Abstract

This experiment was conducted to compare digestive enzyme activity of of nile tilafia with feed formulation contain Hydrolyzed and non Hydrolyzed Leucana leucophala Leaf Meal with Sheep Rumen Liquor Enzyme Extract.  Fish were fed isonitrogenous (± 32% crude protein and C/P ± 9,25 kkal/kg) diets for 50 days in 18 aquarium with a recirculation water system.  12 diets were  formulated to contain hydrolyzed LLM and non hydrolyzed LLM at level 10% 15% 20% 25% and 30% and one diet acting as a control (0% LLM). All diets were isonitrogenous and isoenergy.  A seven week feeding trial was carried out on triplicate groups of eight fish (9.38 ± 0,41) in 36 aquarium with a recirculating system.  Fish were fed twice daily as satiation.  Results of the present study indicate that using hydrolyzed LLMin fed formulation can be incrase protease, amilase and cellulase   enzyme activity in digestive tract nile tilapia.

Abstract

Penelitian ini bertujuan untuk mengetahui jenis-jenis mirkoalga di sumber air taman hutan rakyat sultan adam, Mandiangin dan mendukung fungsi taman hutan rakyat sultan adam sebagai pusat informasi penelitian. Metode yang digunakan adalah purposive sampling dengan 5 stasiun dengan pengulangan 3 kali pada tiap-tiap stasiun. Berdasarkan hasil pengamatan dan identifikasi yang dilakukan pada 5 stasiun, ditemukan enam kelas mikroalga yaitu: Chrisophyceae, Cyanophyceae, Chlorophyceae, Cryptophyceae, Bacillariophyceae, dan Rhodophyceae. Dari enam kelas yang ada terdapat 46 spesies yang berhasil diidentifikasi dengan Chlorococcum sp. adalah spesies yang mendominasi pada 5 stasiun penelitian. Jenis yang paling banyak ditemukan adalah kelas Chlorophyceae sedangkan yang paling sedikit adalah kelas Rhodophyceae, dengan jumlah berturut turut adalah 17 dan 3 jenis mikroalga.

Abstract

Research on identification of parasitic organism in climbing perch (Anabas testudineus) was carried out.  The purpose of the research was to identified parasitic organism which infecting climbing perch including parasitic intensity,  prevalency, and coefisien of corelation.  The result showed that several organs such as gills and intestine, infected parasitic organism. The parasitic organism are Nematoda,  Dactylogyrus sp, and Trichodina sp.

Abstract

The air-stem barks of M.casturi were extracted with Methylene Chloride (MTC). The MTC extract’s had treatment with Brine Shrimp Lethality Test (BSLT) than analyzed with probit and resulted LC50= 47,31 ppm. MTC extract’s was fractionated by Vacuum Liquid Chromatography and recrystalization obtained pure compounds. The compounds was analyzed with GC-MS (Gas chromatography-Mass Spectroscopy) and cytotoxic test with cancer cell Leukemia P388. This compound is limonene and have IC50=70 ppm.

Abstract

Alabio duck as one of the genetic resources of South Kalimantan develop rapidly and well-known as an excellent breed of ducks for egg production in Indonesia. However, due to unplanned crossbreeding in the field, presumely  the productivity and the purity of Alabio ducks decreased.   The study is conducted in order to provide information of the characteristics of body weight, body shape, colour of feather, beak, and shank, and also egg production and egg quality of Alabio ducks at duck farming centers in South Kalimantan.  The results indicated that there are uniformity in body weight,  ≤ 1,5 – 1,6 kg for female and  > 1,6 kg for male at 20-24 weeks of age, bottle for of body shape, 60o elavation, but there are variations in some degree in feather colour, beak colour and shank colour of Alabio duks. The feathers vary between batik (strip) or not-strip with cream as the base color. Meanwhile, the colour of beak and shank vary as light yellow, old yellow and orange.  Unless for the higher egg production (91%) in the intensive system and yellow red yolk colour (12,93 RYCF) in the extensive system, egg qualities are not different between production systems.

Abstract

Pemanfaatan tanah lahan gambut sebagai kompos belum banyak dilakukan. Penelitian pendahuluan mengenai hal tersebut dilakukan dengan mengkomposkan tanah lahan gambut dengan bantuan A. niger dan stimulator EM4. Kemudian diujikan kepada tanaman jagung. Hasil penelitian menunjukkan bahwa kompos tanah gambut terbaik diperoleh dari perlakuan penambahan spora A. niger sebanyak 15 ml dengan lama pengomposan 3 minggu. Kompos tersebut memiliki kadar rasio C/N terendah dibandingkan perlakuan lain yaitu 0.46% dan kadar P total sebesar 195 ppm. Rata-rata berat kering akar, batang, daun serta pipilan jagung memiliki pola yang relatif sama, mengalami kenaikan pada pemberian kompos tanah gambut dengan penambahan spora A. niger 7.5 ml dengan lama pengomposan 1 minggu, yaitu berturut-turut 1.2gr, 0.7gr, 3.5gr dan 0.11gr. Kompos tanah gambut hanya memberikan pengaruh yang nyata pada berat kering daun. Berat kering daun tertinggi (3.5 gr) diperoleh dari pemberian kompos tanah gambut dengan penambahan spora A. niger 7.5 ml, pengomposan 1 minggu.
