Judul: Aplikasi Teknologi Peresapan Biopori untuk Meningkatkan Produksi Padi Gogo pada Pertanian Lahan Kering di Kabupaten Maluku Tenggara Barat
Abstrak: Dryland agriculture in Western South-East Moluccas (WSEM) Regency is still subsistence and depend on rainfall. However, rainfall is not used optimally to increase food production. The purpose of this research was to analyze effectiveness of the biopore infiltration system toward the increase of soil moisture availability, control of ranoff and soil erosion, nutrient loss, and increase of upland rice production in WSEM. One innovation of the land and water conservation technique is biopore infiltration system which consist of biopore infiltration channel and hole. Least significant difference test showed that biopore infiltration system tends to increase the availability of soil moisture in dry period. All treatments except T0 was very significant in controlling runoff and soil erosion, also in saving sediment an decrease nutrient soil loss. The system was able to decrease the runoff up to 99.8 % and 100 % of erosion, T4 treatment was the highest in saving sediment at 9.32 tonnes/ha for one growing season. T3 and T4 treatments significantly increased the growth and production of upland rice in Latdalam village of South Tanimbar sub-district, WSEM regency

Abstrak: Surface runoff and erosion are the main problem causing land degradation on sloping upland agriculture. Biopore infiltration system is one of water harvesting technology developed on arid region. The experiment aimed at studying the effect of biopore infiltration system to control surface runoff and erosion on sloping upland. The research was conducted in Cikabayan experimental farm, University Farm, Bogor, and in ITSL Laboratory, Faculty of Agriculture, Bogor Agricultural University. The Research was done from January 2009 until March 2010. The objective of this research to study the effectiveness of the biopori infiltration system in preventing damage to land by surface runoff and erosion, as well as in improving agricultural production on upland. Completely randomized block experimental design was used to analyze data collected from five treatments arranged randomly in three blocks as replications. Applied treatments were: control (T0); ridge terrace with contour channel according to the size of a width of 20 cm and 15 cm deep in intervals of 2 m (T1); T1 treatment combined with vertical mulching 4 tons of rice straw/ha (T2); T1 treatment combined with 2 infiltration hole in the contour channel at intervals of 1 m, diameter 8 cm and 100 deep, filled with rice straw (T3); and combinations of treatments T2 and T3 (T4). Research results indicated that each treatment very significantly prevents runoff and erosion for corn planting season and upland rice planting season compared to treatment T0. All treatments tends to increasing plant heigh of maize and upland rice except treatment of T2 at corn planting season to treatment T0. Treatment T2, T3, and T4 very significantly increase number of produvtive tillers compared to treatment T0. All treatments tends to increasing dry seed wight compared to T0 except treatment of T4 which is real increased dry seed wight. Treatment with vertical mulch (T2, T3, and T4) had higher seed wight if it is compared to treatment without vertical mulch (T1). All treatments very significantly increase dry rice grain wight if it is compared to T0. Treatment of T3 and T4 tends to produce higher rice grain if it compared to treatment of T1 and T2. Treatment with vertical mulch (T2, T3, and T4) very significantly increased the weight of dry straw if it is compared to treatment T0.

Judul: Beberapa aspek anatomi alat sirkulasi ruang dada kancil
Abstrak: Telah dilakukan penelitian dengan menggunakan 10 ekor kancil dewasa jantan dan betina dengan tujuan untuk menge- tahui beberapa aspek anatomi alat sirkulasi di dalam ruang dada, meliputi jantung, pembuluh darah yang keluar dan ma- suk jantung serta ukuran-ukuran jantung. Kancil merupakan ruminansia terkecil di dunia, hidup di daerah tropika India, Thailand, Malaysia dan Indonesia bagian barat. Hewan ini dilindungi dan mempunyai prospek yang baik untuk hewan penelitian maupun dibudidayakan. Hasil penelitian menunjukkan bahwa berat jantung rаta-rata adalah 0.69% dari berat rata-rata kancil. Dan ini mirip pada jantung kuda dan anjing. Bentuk jantung lonjong seperti halnya ruminansia. Demikian pula letaknya di dalam ruang dada seperti pada ruminansia dengan adanya Ligamentum sternopericardiacum. Di dalam ventrikel kanan membersit sebuah Musculus (M.) papillaris dari dindingnya dan tiga sampai empat Musculi (Mm.) papillares dari Septum interventriculare. Hanya dua buah Mm. papillares yang berukuran besar dibersitkan dari dinding ventrikel kiri. Percabangan Arteri (A.) coronaria sinistra lebih dominan dari pada A. coronaria dextra. Sedangkan A. sub clavia sinistra dicabangkan langsung dari aorta di dorso- caudal pembersitan Truncus (Tr.) brachiocephalicus…
