Judul: Study on the use corrugated fiber board and wood crates packaging for cantaloupe melons (Cucumis melo L.) transportation
Abstrak: Quality of horticultural post-harvest products can not be increase but it can only be maintained. Post harvest handling that appropriate is necessary to maintain product quality,one of them is to make the packaging that can keep the fruit quality to be in a good condition and also to simplify on transportation process. Product quality loss during transportation process create a significant losses into the horticulture business. The main objective of this research is to determine the affect between filler packaging and mechanical damage. The material that being used in this study, which are: melon crates, corrugated fiber board, and newspaper. The equipment used consists of vibrating table with a compressor, the scales mettler, rheometer, and refractometer. The smallest mechanical damage occurred in melons when it packaged in corrugated fiber board and wrapped newspaper, while the worst damage experienced melons are packed with wood crate without filler material. Possessed the lowest hardness melon packing crates with the treatment without filler material. Weight losses occurred in melon with packing crates without filler material. The highest total soluble solids on the last day of observation occured for the melon that packed using corrugated fiber board and melon wrapped in newspaper. Package using corrugated fiber board with melon wrapped newspaper is the best packaging for transportation. It is because mechanical damage that occurs lowest, hardness and total soluble solids are highest, and loss of weight are relatively little during storage of 15 days.

Abstrak: Quality of horticultural products after harvest can not be increase but maintaining it is very important. Postharvest handling that appropriate is necessary to maintain product quality one of them is to make the packaging that can keep the fruit quality to be in a good condition during transportation process. The purpose of this research is to study effect of some packaging types and filler materials to decline in tomato fruit quality parameters and the degree of mechanical damage. The observations were conducted based on the physical quality parameters such as mechanical damage, weight loss, hardness, and total soluble solids. Physical quality parameters of tomatoes were observed before and after transportation simulation. Simulations was performed using a simulator table an amplitude of 2 cm and frequency of 2.75 Hz for 1 hours and an amplitude of 2.5 cm and frequency of 2.75 Hz for 3 hours. From the simulation results after transportation, tomatoes have the same quality changes in each treatment, the level of dissolved solids increases, the weight of tomatoes decreases (shrinkage of high weight), hardness decreased. The longer the simulation of transportation is increased the percentage of mechanical damage. The best packaging for the transport of tomatoes during transport is the treatment of packaging cardboard with a sheet of newspaper as filler material because it has the lowest level of mechanical damage, low hardness degradation, and shrinkage is relatively small weights.

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.
