Abstract

In the early stage of secondary succession process in 1 year old fost fire Kalampangan feat swamp area it was conducted a study on herbaceous plant species composition. The research found 6 fern species and 1 grass species out of 23 species representing 20 families. The coverage area of herbaceous vegetation was 13.12% or 1.312 m2 per hectare, which indicated relatively low percentage. In terms of relative dominance and frequency, herbaceous plant species in the area study was highly dominated by a terrestrial fern Stenochlaena palustris. Some tree species known as secondary and primary forest constituents such as Macaranga caladifolia (Euphorbiaceae), Dyera lowii (Apocynaceae), Combretocarpus rotundatus (Combretaceae), Cratoxylon arboresncens (Clusiaceae), Garcinia sp. (Clusiaceae) and Ploinarium alterifolium (Theacee) were found at their early growth stage on the forest floor but still in lower abundance compared to other recorded species from the study.

Abstract

Gmelina arborea is one of the important trees for forest plantation. It is used for pulp, paper and plywood. Considering that G. arborea is an exotic type, this species has highly risk of receiving pest and diseases. This research was aimed to study the biological characteristics, attack pattern and distribution of stem borers. Studies were conducted in PT. Sumalindo (East Kalimantan). The sampling plot was 20x20 m2, and the plants were stratified based on the plant age. Observations were directed to determine the species of stem borers and the damage they caused. Xyleutes ceramica and Acalolepta rusticatrix were documented attacking G. arborea, with their damage intensity of 13% and 54.8%. These insect attacked 22% and 64.4% of the plant plantation.

Abstract

In Papua, rusa deer (Rusa timorensis) and freshwater turtles constitute the local people bush meat resources through hunting. These hunting activities are produced some by-products i.e. hard antlers from deer and carapace shells from freshwater turtles, where both have a high economic value. The purpose of this study was to investigate the level of production of those by-products and the pathway of the local market being established. The study was conducted at Merauke Regency, Papua, and its vicinity by visiting the key players of all collectors and trade levels. The results showed that on almost all harvested bush meat came from freshwater turtles were cooked on the location, leaving only the carapace shells. Only small quantity of the bush meat was taken home or for trading purposes. However for deer, the majority of hunting activities was done on the purpose for the meat to be sold in the market and small quantity was used for personal needs. Trading on the by-products was conducted at three levels, they were local collectors, middle collectors and local exporter. In general, over 62% of hard antlers samples being observed were uncast hard antlers and 88% of the hard antlers came from the third growth onwards. In a year, at least 1.600-3.700 pairs of hard antlers were acquired, or equivalent to 2.8-6.6 tons. The freshwater turtles being identified were Macrochelodina parkeri, Chelodina reimanni, Macrochelodina rugosa, Elseya braderhorsti and Emydura subglobosa, in which none of the species is under Appendix CITES's list or as Indonesian protected species.

Abstract

Ilmu pangan merupakan disiplin ilmu terkait dengan teknik, biologi, dan fisik yang digunakan untuk mempelajari karakteristik pangan, penyebab kerusakan pangan, prinsip pengolahan pangan, dan usaha peningkatan pangan untuk konsumsi masyarakat. Teknologi pangan merupakan aplikasi ilmu pangan untuk menyeleksi, mengawetkan, mengolah, mengemas, dan mendistribusikan pangan yang bergizi tinggi sesuai dengan rambu-rambu keamanan pangan. Apabila dilihat dari definisinya, teknologi pangan terkait dengan ilmu pangan sebagai basisnya sehingga sering kedua definisi tersebut saling dipertukarkan. Alasannya seseorang yang menguasai ilmu pangan dan teknologi pangan harus memahami karakteristik komponen bahan pangan sekaligus mampu menghasilkan pangan yang bergizi dan aman untuk dikonsumsi.

Abstract

The main objective of this research was to analyze the influence of bait and funnel constructions on the catch of deep sea pot in Palabuhanratu Bay. The experimental fishing used each of 5 units rigid and soft funnel of the deep sea pots filled with bait of shark and ray meat. The result showed that shark and ray baits did not have a significant influence on the weight of pots catch. The rigid and soft funnel constructions also did not have a significant influence on the catch. Therefore, both shark and ray baits used on the deep sea pots for catching fish at the depth of 200 m in Palabuhanratu Bay had the same effectiveness. The rigid funnel pot was a more suitable construction to catch fish, because it was easy to construct, relatively heavy and fast to sink, so it reduced the setting time.

Abstract

Penelitian ini dilakukan untuk mengetahui pengaruh hormon tiroksin dan analog hormon juvenil (metopren) terhadap pola titer hormon ekdisteroid hemolimf selama instar lima Bombyx mori. Instar dua B. mori diberi pakan daun murbei yang telah diberi tiroksin dengan konsentrasi 1500 ppm. Larva kemudian dibiarkan ganti kulit sampai instar tiga dan empat tanpa perlakuan. Tujuh puluh dua jam setelah ganti kulit pada instar lima, larva disuntik sebanyak 10 μl metopren dengan konsentrasi 15 atau 25 ppm. Titer ekdisteroid hemolimf dideteksi dengan Kromatografi Cair Kinerja Tinggi. Hasil yang diperoleh menunjukkan bahwa perlakuan dengan tiroksin ataupun kombinasi tiroksin-metopren menyebabkan terjadinya perubahan pola titer ekdisteroid dibandingkan dengan kontrol. Ekdisteroid terdeteksi dua hari lebih awal pada perlakuan tiroksin dan titer ekdisteroid pada puncak tertinggi lebih tinggi jika dibandingkan dengan kontrol. Kombinasi tiroksin-metopren tampaknya menyebabkan penekanan terhadap titer ekdisteroid. Hal ini terlihat dengan terjadinya penurunan titer ekdisteroid segera setelah penyuntikan dengan metopren sebelum mencapai titer puncak tertinggi.
