Abstrak: New and exciting developments in research of mangosten yellow latex in the past few years greatly contributed to better understanding of the methode to control gamboge in mangosten fruits. A field experiment was conducted to understanding and quantifying the effect of boron (B) and calcium (Ca) application to control yellow latex or gamboges on manggosten fruit. There are five treatments and one control as follow: (1) no fertilizer applied as control, (2) 5.79 kg Ca.tree-1.year-1 applied by soil application (3) 5.79 kg Ca.tree-1.year-1 applied by soil application + 1.553 g B.tree-1 .year-1 applied by soil application, (4) 5.79 kg Ca.tree-1.year-1 applied by soil application + 0.047 g B.tree-1.year-1 applied by foliar application, (5) 1.553 g B.tree-1 .year-1 applied by soil application, (6) 0.047 g B.tree-1.year-1 applied by foliar application. The experiment was laid out on a randomized complete block design. The treatment of 5.79 kg Ca.tree- 1.year-1 applied by soil application + 1.553 g B.tree-1 .year-1 applied by soil application significantly affect to reduced yellow latex in aril till to 0%, reduced yellow latex scoring in aril, increasing boron content in endocarp. However they were not significant affect on fruit weight, fruit diameter, fruit fluident, total soluble solid (TSS), total acid titrated (TAT), Ca in leaves, Ca in pericarp, B in excocarp, and B in mesocarp.

Abstrak: The yellow sap contamination causes low quality of mangosteen. Yellow sap contamination occurs due to weak cell walls in the fruit. Weak cell walls caused by low calcium and boron. Calcium has a function to strengthen the integrity of the cell wall and boron provide the stability maintenance of the cell wall. This research aims to examine the combination of calcium and boron with a low dose to reduce yellow sap contamination in mangosteen. The research was located in 3 mangosteen orchard in Cigudeg, Citeureup, Sukabumi, and analysis of samples in Post Harvest Laboratory of Bogor Agricultural University in November 2014 to March 2015. The research was designed by Randomized Complete Block Design (RCBD) with one factor of the combination of calcium and boron dose. The treatment consisted of 5 levels that repeated 4 times with each repetition consisted of one tree so that the number of mangosteen tree is 20 trees in each experimental orchard. In each tree, 20 fruits were collected randomly. The combination of fertilizers that used in this research was without fertilizer (control), 1 kg Ca / tree + 0.047 g B / tree, 1 kg Ca / tree + 1.553 g B/ tree, 1.5 kg Ca / tree + 0.047 g B / tree , and 1.5 kg Ca / tree + 1.553 g B / tree. The results of this research indicated that the most effective dose to reduce contamination of yellow sap in mangosteen in three experimental orchard was a dose of 1.5 kg Ca / tree + 1.553 g B / tree. The application of calcium and boron at a dose of 1.5 kg Ca/tree + 1.553 g B/tree significantly reduced scores and percentage of yellow sap contamination on peel and aryl of fruit, and did not affect the physical and chemical quality of mangosteen fruits.

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.
