Abstrak: Dari sekitar 4.000 jenis pohon yang ada di hutan alam Indonesia diperkirakan hanya 400 jenis yang dianggap penting. Dari 400 jenis tersebut, 259 diantaranya sudah diketahui sifat dan kegunaannya serta telah diperdagangkan dan dikelompokan kedalam 120 jenis kayu perdagangan Indonesia. Sisanya, yaitu yang belum diketahui sifat-sifatnya, juga sudah diperdagangkan dengan harga yang lebih rendah meskipun kayu-kayu tersebut belum tentu memiliki nilai guna yang lebih rendah dari kayu-kayu yang sudah lebih dulu dikenal.

Judul: Struktur Anatomi dan Sifat Fisis serta Alternatif Tujuan Penggunaan Tiga Jenis Kayu Asal Kalimantan
Abstrak: Wood is a product of living organism that has special characteristic and appearance. Every single species has its own character. Indonesia has about 4000 species of woody plants, but only 95 species have been studied comprehensively. Therefore, study on wood properties is very important not only for determining their proper utilization, but also for better processing and further treatments. Among thousands of existing wood species in Kalimantan, utilization of Belangeran (Shorea Balangeran (Korth.) Buck), Bungur (Lagerstroemia speciosa Pers.) and Medang (Cinnamomum spp.) woods is still limited and has not optimize yet. Through well understanding of their wood characteristics and properties, utilization of these three wood species become more optimize. It was hope that these three woods could be utilized as the alternative to replace the conventional species which tended to decrease year by year. The main material used is a small piece of wood (a disc 5 cm thick) extracted from tree stem at 1.3 meters above the ground from each species. From each disc, wood sample for every measurement was taken representatively following procedural standard. Macroscopic characteristics consist of wood color, figure, texture, grain, lustre, odor and hardness, while microscopic characteristics consist of pore (its arrangement and distribution, perforation plate, pitting structure on the cell wall and contain); ray parenchym (its size, composition and contain); type of axial parenchym and fiber morphology. Microscopic observation was conducted through the maceration specimens of Schlutze and the microtome specimens of Sass. Physical properties of wood consist of moisture content as well as density and specific gravity. The result showed that wood color of three species studied varied: reddish brown in Belangeran, pale brown to reddish in Bungur and yellowish brown in Medang. Heartwood and sapwood demarcation is clearly distinguished only in Belangeran wood, while growth ring is clearly only in Bungur wood. Diffuse pattern of pore was found in Belangeran and Medang woods, while ring porous pattern in Bungur wood. Generally, their vessels are solitary and radially multiple 2-4 cells. Vestured pit, tilosis and axial intercellular channels are the specific characters of Belangeran wood, while Bungur wood are vestured pit and prismatic crystal. Specific characters of Medang wood is yellowish white of amorphous material and oil cell (laticifer). Regarding to pulp and paper raw material, fiber quality of three wood species studied belong to Class III. In term of strengthness, these three wood species are suitable for structural purposes: Belangeran is for Strength Class II, while Medang and Bungur Strength Class III. Belangeran and Bungur woods are also potential as raw material of meubel and furniture.

Abstrak: Dalam Rancangan Pelita Ketiga (1979/80 - 1983/84) dijelaskan bahwa tujuan pembangunan antara lain adalah me ningkatkan mutu gizi pola komsumsi masyarakat melalui pe- ningkatan penyediaan karbohidrat, protein dan vitamin. Selain daging dan susu, telur adalah sumber protein hewani yang sangat penting. Oleh sebab itu dalam rangka peningkatan penyediaan protein pemerintah terus berusaha meningkatakan produksi telur dengan menggalakan peternak- an rakyat dan peternakan komersil yang telah maju. Peter- nakan yang telah maju dapat berfungsi sebagai pusat latih an dan pengembangan usaha peternakan rakyat disekitarnya. Mereka dapat sebagai sumber bibit dan tehnologi bagi pe ternakan rakyat. Menurut data dari Bulletin Statistik dan Ekonomi. Ter nak (1981) produksi telur dari Repelita I sampai Repelita III terus meningkat. Dalam Repelita I terdapat kenaikan produksi telur +4,2% per tahun. Dalam Repelita II produk- si telur meningkat +13,8% per tahun dan dalam 2 tahun Re- pelita III (1979-1980) terdapat kenaikan rata-rata produk si telur +6,93% per tahun. ...
