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: New technological innovations to reduce water and soil losses from agricultural land such as application of biopore absorbtion hole is very important. Reduction of water loss from agricultural land is required to maintain and improve soil fertility to support plant growth optimaly. This research purpose to study the effect of biopore absorbtion hole to reduce surface runoff, erosion, nutrient losses and increase productivity of corn (Zea mays) and upland rice (Oryza sativa). The research was design using randomized block design with soil conservation techniques as the treatment. The treatments consist of: no soil and water conservation techniques (T0), the conventional ditch (T1), conventional ditch and vertical mulch (T2), conventional ditch and biopore absorbtion holes (T3) and conventional ditch, vertical mulch and biopore absorbtion holes (T4). Measurement of surface runoff and soil erosion was conducted on soil erosion plot (10m x 2m). The parameters were observed included surface run-off, soil erosion, sediment deposited in the ditch, the content of C, N, P, K, Ca and Mg on the surface runoff and soil eosion which are deposited on ditch, and plant growth and productivity of corn and upland rice. The treatments of T1, T2, T3 and T4 are very effective in reducing surface runoff and soil erosion which is equal up to 100% compared with no treatment (T0). There treatment were also reduce nutrients losses in to ditch so that not loss from farmland. T4 treatment is able to precipitate nutrients to ditch more than the other on corn and upland rice season. The treatments T2, T3 and T4 significantly effect to dry weight of biomass and grain production of upland rice. The highest of biomass and grain upland rice production was found in the T4 treatment, respectively 7.20 ton/ha and 9.51 ton/ha. Effect of treatments and sediment return from ditch to planting bed were positive impact on production in the next planting season.

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…
