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.

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

Judul: Leukemia pada kucing
Abstrak: Leukemia pada kucing adalah suatu penyakit yang sangat patogen, disebabkan oleh sejenis virus. Virus ini dikenal sebagai Feline Leukemia Virus atau FeLV. FeLV ini oleh beberapa ahli dikatakan hanya bersifat ganas pada hewan kucing. Penularannya bisa secara horizontal maupun congenital. Kucing pada semua tingkat umur dapat terserang oleh FeLV ini. Khusus pada bentuk "thymic leukemia", virus ini hanya menyerang anak-anak kucing berumur diba- wah 1 tahun. Kucing-kucing liar atau yang tidak terpeli- hara jarang sekali terinfeksi FeLV. Selain dari serangan virus FeLV itu sendiri, maka penyakit leukemia ini bisa disebabkan oleh beberapa fak- tor yang sudah ada dalam tubuh hewan dan sangat menunjang perkembangan penyakit ini, yaitu antara lain tumor, agen toksik, cedera oleh kecelakaan dan gangguan hemopoiesis. FeLV menyerang sel-sel darah dalam tubuh hewan se- hingga pembentukan darah berjalan tidak normal. Terlihat sel-sel darah yang belum dewasa sudah beredar dalam sir- kulasi darah. Bentuk dan jumlahnya tidak lagi seimbang dalam tubuh hewan kucing tersebut. Gejala klinis antara lain kekurusan, ikterus, anemia, lemah, anoreksia, dyspnoe, sulit menelan, batuk, dan membran mukosa pucat. Selain itu kelenjar pertahanan tubuh juga membengkak, kemudian terjadi hepatomegali, spleenomegali dan pembengkakan pada ginjal. Terbentuk massa tumor pada beberapa tempat. Secara biopsy pada sumsum tulang akan terlihat be- berapa perubahan. Sumsum tulang berwarna merah tua atau abu-abu. Konsistensinya lunak dan terdapat banyak sekali memproduksi sel darah putih. Melalui gambaran darah leukemia ini lebih mudah didiagnosa. Jumlah retikulosit rendah sekali. PCV 8-15%, hemoglobin menurun, sel darah putih (WBC) meningkat, lim- fosit meningkat, Alfaglobulin juga ada peningkatan, dan banyak eosinofil yang belum dewasa beredar dalam darah…dst
