Judul: Studi peranan lingkungan (sifat kimia dan fisika tanah serta cuaca) terhadap cemaran getah kuning buah manggis (Garcinia mangostana)
Abstrak: Yellow sap contamination is a major problem caused the poor quality of mangosteen fruits for export. The research aimed to study (1) variability of yellow sap contamination in some mangosteen production centers (2) variability of soil chemical properties and their effects on the yellow sap contamination, (3) the variability of soil physical properties and their effects on the yellow sap contamination, (4) variability of rainfall as controlling water balance and its relationship with the yellow sap contamination of the mangosteen fruit. The study was conducted at 10 mangosteen production centers, namely Karacak and Barengkok (Bogor, West Java), Garogek and Pusaka Mulya (Purwakarta, West Java), Koto Lua, Baringin, Pakandangan, Padang Laweh, and Lalan (West Sumatra), and Sukarame (Lampung).

Judul: Pengaruh Aplikasi Kalsium dan Biopori terhadap Cemaran Getah Kuning dan Kualitas Buah Manggis (Garcinia mangostana)
Abstrak: Gamboge disorder is the major problem limiting marketable yield of mangosteen fruit. Soil calcium (Ca) application has been known to control the gamboge disorder, but the absorption of calcium occasionally becomes ineffective. The objectives of this research are to find the effect of calcium and biopore application to reduce gamboge disorder and increasing quality of fruit. This research was conducted from November 2010 to April 2011 in mangosteen farm at Karacak, Leuwiliang, Bogor and Postharvest Laboratory, Department of Agronomy and Horticulture IPB. The treatment design is based on Randomized Completely Block Design with two factors. The first factor was concentration of calcium and the second factor was biopore application. There were five concentrations of calcium; 0 kg Ca2+/tree/year; 5.33 kg dolomit/tree/year; 3.55 kg kalsit/tree/year; 10.67 kg dolomit/tree/year; 7.11 kg kalsit/tree/year and there were two treatments of biopore; without biopore application and with biopore application. The result showed that calcium factors were significant to reduce gamboge disorder, but the bi opore factors didn’t give significant effect to reduce gamboge disorder. Interaction between 7.11kg kalsit/tree/year with biopore technology were effectif to reduce gamboge disorder in mangosteen peel. In aril, interaction between 5.33 kg dolomit/tree/year with and without biopore technology, were give significant effect to reduce gamboge disorder in aril.

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.
