Judul: Male Rabbits Weaning of Response which given Root Tubers as Source Alternative Energy in Ration Kind of Pellet.
Abstrak: An experiment was planed to know the male rabbits weaning of response which given root tubers as source alternative energy in ration kind of pellet. Twenty male rabbits of weaning had a mean of live weight 271 ± 32 g which old age 4-5 week. Exploiting and information about usage of root tubers as energy resources still very limited. While rabbit livestock. specia11y weaning rabbit at a periode of growed needed more energy resources compared to adult rabbit, so in this research tried some energy resources of root tubers, such as sweet potatoes, cassava and tannia in rabbit ration. An experimental method was used Completely Randomized Design with 4 treatment and 5 replication. Treatment given kind of pellet with source of different energy that is RI: energy resources of maize; R2: energy resources of sweet potatoes; R3: energy resources of cassava; R4: energy resources of tannia. The results are analyzed with ANOVA and Duncant Test to know difference between treatment (Steel and Tonie, 1993). The observed parameters were feed conswnptio~ water consumptio~ daily weight gai~ feed efficiency, mortality and economic value. The results showed that the treatment were significant ( P<O.05) on dry mater intake. but not significant on water consumptio~ daily weigth gain, feed efficiency and feed convercy. It was concluded that usage of sweet potatoes, cassava and tannia as energy resources at level 300/0 can used t!J feed alternative for rabbits because are given a good response and economic value.

Judul: Energy Digestibility of Cross-Breed Weanling Rabbits as Influenced by Substitution of Soybean Meal of Bauhinia purpurea L
Abstrak: Bauhinia purpurea L. is one of the alternatif ration. Rabbit can be fed Bauhinia purpurea L. due to its high protein content. A major advantage of rabbit meat appears to be in its chemical composition. It is low in fat, cholesterol and salt. A particulary attractive aspect of rabbit production is that it does not have to compete with man for feed sources, nor directly with the traditional species used in the intensive animal industry. ' The energy consumption, digestible energy and energy digestibility value were measured in this experiment. The experiment was conducted in Lab. Ruminansia Kecil, Department of Animal Production Science, Faculty of Animal Science, Bogor Agriculture University. This experiment was carried out during August to October 2002. Twenty male cross-breed weanling rabbits with the initial avarage body weight 853 ± 117 gram were used.

Judul: Gelombang soliter internal pada lapisan atmosfiri yang memiliki perubahan kecepatan angin yang cepat
Abstrak: Gelombang internal adalah suatu gelombang yang terjadi di dalam suatu fluida. Gelombang ini muncul karena adanya perubahan rapat massa di setiap lapisan di dalam fluida. Salah satu gelombang internal yang ditemui di lappisan atmosfir adalah gelombang soliter internal, seperti yang terjadi pada fenomena "morning glory" di Australia. pada fenomena "Morning glory" terjadi penurunan tekanan hingga bebrapa milibar.
