Judul: Pengkajian Kemasan Karton Untuk Transportasi Buah Alpukat (Persea Americana, Mills).
Abstrak: During transportation and storage the packages produce faces numerous hazards, these may be mechanical, environmental, or biological. Mechanical hazards can be defined as those caused by impact, vibration, compression and puncturing. This research to study using the Cartons for transportation avocado and how interaction with the material substance the carton and the temperature of storage to keep the quality of avocado during simulation transportation. Factorial completely randomized design with two treatments of size cartons (capacity 7 Kg and capacity 15 Kg to packaging the avocado), tree treatments of the material substance the carton (cut of newspaper, the newspaper that wrap every avocado and nothing the material substance the carton ), and two treatments of temperature storage (5oC and 28oC). After the packaging, the avocado do simulation transportation with vibration table during 2 hours with the amplitude 3.2 cm and frekfuensi 3.4 Hz . After the simulation transportation the avocado experience to sorting, then avocado have storage at 5oC and 28oC. The quality parameter have to measure are mechanical hazard, reduction of weigh, hardness, and content of sugar. The research show that the size cartons, kinds of the material substance the carton and temperature of storage have different Mechanical hazards, reduction of weigh, hardness, and content of sugar. The result from simulation transportation show that the packaging with carton where capacity 7 Kg, using the cut of newspaper, and storage in 5oC are the best packaging to transportation the avocado in long distance, in stone of road as well as the road.

Judul: Kajian Pengaruh Tipe Ventilasi dan Suhu Penyimpanan Terhadap Perubahan Mutu Buah Alpukat (Persea Americana,Mill) dan Sebaran Suhu Dalam Kemasan
Abstrak: Post harvest handling of avocado in Indonesia usually are still done with less carefull during harvesting, packaging, transportation, and storage can lead to mechanical, physiological, chemical, and microbiological damage. Mechanical damage during the distribution process of fruits due to impact between fruit inside the packaging, the impact of the fruit with a wall packaging, as well as the excess pressure due to pile in one package. The use of corrugated box packaging by giving insulation between the fruit and ventilation holes are expected to reduce mechanical damage and changes in avocado fruit quality such as shrinkage weight, hardness, total soluble solids, and physical damage during storage. This research was done to investigate four packaging types : packaging without ventilation, circle type ventilation packaging, oblong type, insulation type; and two treatment of storage temperature of room temperature and 8 0C temperature. The testing result in the temperature distribution on the packaging indicates that the packaging with oblong ventilation type most quickly reach the expected storage temperature. The transport simulation results of the which was equivalent with 184.82 miles in the road out of town or approximately 3:08 hours for trucks with speed of 60 km / h shows the level of fruits mechanical damage in 0% on all packaging. Although the package with oblong ventilation is better in distribution temperature, but overall, the decreasing quality of avocado in circle ventilation package is slower than the other packages. Due to, the best package to be distributed the avocado is package with circle ventilation in temperature of 8 oC.

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.
