Judul: Pengaruh Berbagai Variasi Suhu Tekan Terhadap Daya Rekat Casein Pada Tripleks Damar
Abstrak: Pertjobaan pengudjian kekuatan daja rekat dua formu- la casein pada tripleks kaju damar (Agathis loranthifo lia SALISB) jang direkat setjara tekan panas telah dila- kukan dengan metode " plywood strip shear test". Formula perekat casein jang dipergunakan adalah formula 4B (U.S. patent no.1.291.396 atas nama S. Buttermann, 1918) terdi- ri atas tjampuran casein, kapur tohor, natrium silicate, air dan formula 11 (U.S. patent no.1.456.842. atas nama S. Buttermann dan C.K.Cooperrider, 1923) terdiri atas tjampuran casein, kapur tohor, natrium silicate, tembaga chlorida dan air. Suhu tekan jang dipergunakan adalah 70, 80, 90, 100, 110, 120, 130 dan 140°C. - Tripleks dibuat dari finir berukuran 10 x 6 cm, te- bal finir 1,5 mm, berserat lurus dan rata serta tidak mem- punjai mata kaju atau petjah-petjah. Kadar air finir ke- ring udara sekitar rata-rata 15 persen. Banjaknja perekat basah jang dipergunakan (glue spread) kira-kira 30 mg per cm persegi, masa tunggu tertutup (close assembly time) antara 10-20 menit, ...

Judul: Mempelajari Pengaruh Penambahan Beberapa Bahan Penglkat Terhadap Daya Tahan Pecah Keripik Tempe Kedelai
Abstrak: Tempe kedelai merupakan h"sil dari fermentasi kedelai menggunakan kapang Rhizopus sp. Tempe merupakan bahan makanan yang mudah rusak dengan umur simpan hanya satu atau dua hari pada suhu kamar. Pembuatan keripik tempe tanpa penggorengan merupakan salah satu cam untuk memperpanjang umur simpan tempe sekaligus untuk memberi nilai tambah pada keripik tempe, sebagai pangan fungsicnal. Salah satu kendala dari keripik tempe tanpa penggorengan adalah mudah pecah pada saat didistribusi, karena itu perlu dilakukan penelitian menggunakan bahan pengikat untuk memperkuat daya tall an pecah keripik tempe agar tidak mudah pecah. Bahan pengikat yang ditambahkan adalah A I, A2, A3 dan A4.

Judul: Habitat characteristics of timor friarbird philemon inornatus in Camplong Landscape Kupang District, East Nusa Tenggara
Abstrak: Timor Friarbird (Philemon inornatus, G. R. Gray, 1846) is one of the six endemic birds of Timor and is a protected species. The population of bird is suspected to have been decreasing over the past six years along with the decreasing of the quantity and quality of physical and biotic factors of its habitat. Knowledge on landscape spatial pattern could be used to evaluate the quantity and quality of habitat. This research aimed at identifying spatial habitat characteristics of Timor Friarbird based on dominant factors of physical and biotic habitat components. Principle Component Analysis (PCA) on the physical habitat factors showed that variables that have strong correlation with the presence of the bird were Normalized Difference Vegetation Index (NDVI), slope, distance from secondary forest, distance from bush, distance from cashew plantation, distance from crop plantation, and distance from roads. The biotic factors that have strong correlation with the presence of Timor Friarbird were the total number of plant species, number of plants used for food and cover, and mean height of trees. Height of poles was the only variable that has no correlation with the presence of Timor Friarbird. The most dominant physical and biotic factors that influent the presence of Timor Friarbird at a site are the density of foraging trees, slope, distance from the river, the distance from secondary forest, the density of cover pole and the distance from road. The estimation population of Timor Friarbird in Camplong region is low; this might be caused by low feeding tree density, high rates of poaching, the uneven distribution of feed vegetation and the flowering season, habitat degradation due to illegal logging, grazing cattle in the wild, and invasion of siam weed or chromolaena (Chromolaena odorata). The results of land cover classification at Camplong region based on Landsat_5 Thematic Mapper (TM) image with ArcGIS 9.3 and Erdas 9.1 obtained 11 land cover classes, with shrub as the dominant class.
