Judul: Performance test of walking type cultivator for weeding on peanut gajah variety
Abstrak: Peanut plant weeding was commonly done manually utilize sickle, hoe, and by hand. Objective of the research was to test walking type cultivator performances included of weed cover, weeding efficiency, weeding field efficiency, plant productivity, weeding cost, and compare weeding results manually and mechanically. Results of the research showed that weed cover after first and second manual weeding were 0% and 2.36% , while it was done mechanically were (0.35-3.31)% and (3.52-18.40)%. First and second manual weeding efficiencies were 100% and 89.41%, while it was done mechanically were (72.79-96.70)% dan (56.38-78.89)%. First and second mechanical weeding field efficiencies were (49.33-73.49)% and (37.85-56.86)%. Peanut wet pods productivity manually and mechanically were 3.18 ton/ha and (1.28-1.71) ton/ha. Weeding cost manually and mechanically were Rp 1,214,286/ha and (Rp 570,877/ha – Rp 904,387/ha).

Judul: Varieties of Peanut (Arachis hypogaea L.) Response on Weeding Frequency
Abstrak: The presence of weeds in peanut cultivation can suppress the growth, development, and productivity of peanut plants. The use of varieties and weeding is one of the efforts to suppress weed growth in the peanut area. This study aimed to study the response of several peanut varieties to the frequency of weeding weeds to compare the growth and yield of peanut plants. This research design used a factorial completely randomized block design (RKLT) consisting of two factors, namely peanut varieties (Hypoma 1, Talam 1, and Tasia 2) and weeding frequency (without weeding, 1x weeding, and 2x weeding). The results showed that the variety had no effect on the total dry weight of weeds, number of leaves, number of empty pods, plant fresh weight, and productivity. Weeding frequency treatment significantly affected weed dry weight, plant height, number of leaves, fresh and dry weight of peanuts, number of pods, dry weight of pods, and productivity. The 2x weeding treatment gave significantly different growth and productivity results from other weeding frequencies with the highest average productivity of 2.4 tons ha-1. The interaction of the two factors on the yield of peanuts had a significant effect on the total number of pods and the number of filled pods. The higher weed competition in peanut plants can suppress the growth and productivity of peanut plants

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.
