Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh interaksi antara campuran NAA dan Kinetin  terhadap pertumbuhan tiga kultivar buah pisang secara teknik kultur jaringan.  Penelitian dilakukan dengan RAL dua factor, dengan zat perangsang tumbuh terdiri dari 6 kombinasi NAA (0,4, 0,8, dan 1,2 mg l-1) dan Kinetin (6 dan 9 mg l-1), menggunakan 3 kultivar pisang (kepok, uli/mauli, dan raja). Pengamatan secara kuantitas dilakukan terhadap persentase hidup, kontaminasi dan saat pembentukan kalus, dan secara kualitas terhadap defferensiasi morfologi eksplan pada minggu ke 4, 8 dan ke 12 setelah penaburan dengan satuan penilaian tertentu.  Dari hasil percobaan tidak ditemukan interaksi antara campuran NAA dan Kinetin dengan kultivar pisang terhadap semua peubah  pengamatan.  Perlakuan NAA 0,4 mg l-1 + kinetin 6 mg l-1 kultivar pisang mauli memberikan  hasil yang tertinggi terhadap persentase hidup eksplan yaitu 87,5% dan persentase kontaminasi terendah yaitu < 5% sedangkan pemberian NAA 0,8 mg l-1 + kinetin 9 mg l-1 kultivar pisang kepok memberikan saat pertumbuhan kalus yang tercepat yaitu 11 hari.

Abstract

The capability of Acetobacter xylinum to convert carbohidrate of rice-bran to cellulose was studied. Six treatments: 0, 1, 5, 10, and 20 g/L of rice-bran water were applied, and the thickness, weight and fiber from cellulose as fermentation results were recorded. It was discovered that higher concentration of rice-bran increased the thickness, weight and amount of fibers. Significant increase in fiber were found among 1 g/L, 5 g/L, and 10g/L of rice-brand. Higher concentration of rice-brand did not produced significant increase in fibers.

Abstract

India ink was used to examine the role of the yolk stalk lumen as a distinct pathway between the yolk sac and gut through the first 5 d of post-hatch growth in broiler chicks. Two hundred and sixteen newly hatched broiler chicks were equally divided into three treatment groups; gavaged via the esophagus (TRT1), injected in the yolk sac (TRT2) with 0.2 mL of water-based black India ink and  third group of chicks were used as untreated controls (TRT0). Tissue samples of the small intestine, yolk sac, and yolk stalk were removed and fixed in 10% buffered neutral formalin and were processed routinely, embedded in paraffin, sectioned at 5 to 6 µm, and stained with hematoxylin and eosin. The relative concentration of India ink in each of the tissue preparations was detected with a light microscope and assigned a relative score between 0 and 3, with 0 indicating the lowest and 3 the highest amount of ink present. The results show India ink was able to pass from the yolk sac through the yolk stalk and into the intestine, but was not able to pass from the intestine into the yolk stalk or yolk sac. It was concluded that India ink was useful materials in establishing that the yolk stalk provides a direct one-way passage by which material in the yolk sac may move into the intestine of broiler chicks during the first 5-d after hatching.

Abstract

Krakatau archipelago is one of the sea conservation which has a coral reef ecosystem dominated by those of branching type. On the other hand, Krakatau archipelago water is an international traffic line for ships along with hemmed in two regions, Bandar Lampung and Banten. Various human activities may lead to pollution, such as Cu which may enter the Krakatau archipelago waters and accumulate in their biota, including the sessile branching coral. The purpose of this research was to discover the concentration of Cu on branching coral reef in Sertung Island, Panjang Island, and Rakara Besar Island which are the part of Krakatau archipelago waters. The result indicated a level of pollution in Krakatau archipelago waters. The mean concentration of Cu in the three islands was 0.032 ppm. Presumably, the largest contributors of Cu pollutant in the Krakatau archipelago water are navigation activities through the strait and other human activities.

Abstract

Subterranean termites is one kind of termites that live in the soil.  This termites build their nest and find their food in the soil and the woods and trees is as a mainly food for their life. Because of their activities, the subterranean termites as a dangerous animals. The aims of study is looking for and found the kind and the diversity of subterranean termites that live under the rice straw and the bagasse .This research is done with cluster random sampling and collected by baiting technique.   Seven kind of subterranean termites from genus Macrotermes, Microtermes, Odontotermes and Capritermes. All of the  species is subterranean termites, except Capritermes are not potential to destroy the woods.
