Abstrak: Kampung chicken is often cultivated in Indonesia in semi-intensive and extensive. This chicken has slower growth than broiler. A four weeks kampung chicken old has weight 0.20 kg while broiler has weight 1.2 kg, but kampung chicken could digest crude fiber more than 5% of the nutrient content of the feed. Rice and cassava are widely grown in lowland as well as highland and their residual processing can be used as feed. The purpose of this study was to investigate the performance of kampung chicken fed rice bran and cassava leaves. Rice bran and dried cassava leaves were stirred in warm water before feeding to the chickens. Treatment feed was given to the chickens aged 5-12 weeks (P2) and 8-12 weeks (P3) in pasta form. The control (P1) was given commercial feed at the age of 0-12 weeks. The analysis showed the feeding method influences the body weight of kampung chicken. The highest body weight showed in P1 with lowest feed conversion. The lowest body weight showed in P2 with highest feed conversion. Treatment P3 resulted body weight and feed conversion between P1 and P2. The highest mortality (13.33%) showed in P2. Rice bran and cassava leaves were good to give to kampung chicken in 9 weeks to replace commercial feed.

Abstrak: In this research, kampung chicken was fed with rice bran and cassava (Manihot esculenta Crantz) leaf as alternative feed. This research investigated the effect of feeding rice bran and cassava leaf to percentage of carcass and commercial cuts of twelve weeks old kampung chicken. The chickens were fed by commercial feed 100% (P), by rice bran 75% and cassava leaf 25% from 5th- 12th weeks (Q), and by rice bran 75% and cassava leaf 25% from 8th-12th weeks (R). This research was factorial completely randomized designed (RAL) with 2x3 pattern. Data was variant analyzed (ANOVA). The analysis showed the feeding method influence the percentage of carcass and commercial cuts of kampung chicken. The highest pencentage showed in P treatment whereas the lowest in Q treatment. Feeding by rice bran and cassava (Manihot esculenta Crantz) leaf began 5th weeks showed decreasing percentage of carcass and commercial cuts of kampung chicken. Rice bran and cassava leaf can be fed to 8-12 weeks old chicken resulting of 0.7-0.9 kg body weight and also showed the percentage of commercial cuts same as fed by 100% commercial feed (P) except wing parts (P<R).

Abstrak: Gravitational field equation can be formulated in differential forms (differential geometry), which describes gravity as a manifestation of the curvature of space-time. Curvature of space-time is characterized by a metric that satisfies the gravitational field equation. With differential forms it can be formulated the (anti-) self-dual Einstein equation, which is a modification of the Cartan structure in (anti-) self-dual basis. Calculation of (anti-) self-dual metric with (anti-) self-dual Einstein equation is simpler than the calculation using Christoffel symbols.
