Judul: The Response of 10 Cassava Genotypes (Manihot esculenta Crantz) to Three Level of Liming in an Ultisol Soil Gajruk ( Typic Haplohumult)
Abstrak: The response of 10 cassava genotypes was studied in an experiment in which they were grown in polybag for 3 months in an acid Ultisol soil. This research was undertaken to evaluate of 10 cassava genotypes in an Ultisol soil and to identi cassava genotype that can used as source of gene that control adaptive character in this soil. This research was performed in field experiment of Bogor Agriculture Institute, on Mei until September 2001. The experimental designed used was Randomized Complete Block Designed with two factors. The first factor was 10 cassava genotypes as follows : MLG 10073(G1), MLG 10054 (G2). MLG 10114 (G3), MLG 10188 (G4), MLG 10128 (G5), MLG 10157 (G6), CMM 96025-25 (G7), CMM 95014-13a (G8). CMM 9603-190 (G9) and Sri Gading (G10). The second factor was three level of liming (0, 10 and 20 ton/ha). The fertilizer in this study were NPK (5 g/polibag) and urea (2,5 g/polibag).

Judul: Factorial effect on matter accumulation and chemical characteristics, and related characters in cassava (Manihot esculenta Crantz)
Abstrak: his study was carried out to anaJyze varietal differences on matter accumulation and chemical characteristics, and to screen the relationship of major growth characters with DM accumulation and chemical constituents in 4 varieties of cassava. The sweet varieties developed a sufficient source and canopy in short period at the early growth phase and then translocated assimilates to storage roots with a higher partitioning rate, even these varieties were considered as early-maturing varieties from the standpoint of the accumulation rates of STC and DM in roots. Moreover. the sweet varieties showed early-bulking characteristics having superior source and sink potentials for the increase of DWR and accumulation of DM in roots. The direct effects of TDW, R/SR, and LAI on the DWR were higher, while the R/SR, mw, DWL, and LAI showed higher direct effects on the STC. These characters were considered to be useful target characters to screen cassava varieties with higher tuber yield and STC. The HCNL and HCNR began to decrease after 5-7 and 3 MAP, respectively, except for Pucuk Biro showing a delayed accumulation of HCNR until 7 MAP. The HCNL showed relatively higher positive correlation (r=0.639) with the HC which was highly affected by NL, LAI, OWL, and LAD. The LAI, DWR, and STC gave higher negative direct effects on the HCNL and HCNR. At the harvest time, Gading was coosidered to be sweet with 5.8 mg HCNR 0 g-1 fresh weight, while Adiral seemed to be intermediate, containing 17.0 mg HCNR

Judul: Infeksi Virus Parainfluenza Pada Anjing
Abstrak: Virus parainfluenza anjing termasuk famili Paramyxoviridae, berbentuk pleomorf dengan ukuran bervariasi (bergaris tengah antara 100-500 nm), berpembungkus peka ether, berisi genom RNA dan secara serologis mempunyai kesamaan dengan virus SV-5 kera; dikenak sebagai salah satu kausa penting dari sindrom "kennel cough". Infeksinya dapat mengenai anjing semua umur yang belum pernah terinfeksi atau mendapatkan vaksinasi mengakibatkan gejala klinis ringan yang terbatas pada traktus respirasi atu infeksi yang secara klinis tidak memperlihatkan gejala nyata. Gejala klinis yang nampak setelah masa inkubasi (1-5 hari) terlewati berupa batuk yang tidak berat selama beberapa hari, berbagai tingkat tonsilitis dan pharyngitis dan kadang-kadang ditemukan kenaikan temperatur rektal antara 1-2 derajat C dari temperatur normal rat-rata. Anjing terinfeksi mengandung virus pada traktus respirasi bagian atas dan bawah serta limfonoduli sampai hari ke 9 setelah infeksi. Penyebaran virus antar anjing terjadi secara aerogen.
