Judul: Performa dan Respon Fisiologi Ayam Broiler yang Diberi Ransum Mengandung 1,5% Ampas Buah Merah (Pandanus conoideus) pada Waktu Pemberian dan Suhu Kandang yang Berbeda
Abstrak: The aim of this study is to knew the physiological response and performance of broiler fed with 1.5% red fruit waste at different time feeding and cage temperature. 240 heads Cobb strain broiler were used in factorial completely randomized design with two factors and four replications. The first factor was cage temperature: K1: normal cages (28.9±1.0oC); K2: hot cages (31.4±1.0oC); K3: comfortable cages (24.6±1.0oC). The second factor was red fruit waste feeding time: W1: starter period and W2: finisher period with 10 heads of broiler. Parameter used were cumulative feed intake, cumulative water consumption, body weight gain, cumulative feed conversion, final body weight, carcass percentage, mortality, performance index, behaviour, viscera percentation, body temperature and heterophil:lymphocyte ratio. Data obtained were analysed by SPSS.17 program. Red fruit waste fed at starter priod were showed higher stress depcession compared with finisher period. Base on these result, it can be concluded that there were interaction between red fruit waste feeding period and cage temperature in body temperature on day-39. 1.5% red fruit waste feeding in broiler were the best on finisher and gave best response in the comfortable temperature (24.6±1.0oC).

Judul: Performa Ayam Broiler yang diberi Sinbiotik Campuran Tepung Ubi Jalar Merah dan Ragi Tape pada Periode yang Berbeda
Abstrak: This research aimed to assess the effect of red sweet potato meal and tape yeast as a mixed synbiotic on performance of broiler in different periods. This experiment used 200 day old chicks (DOC) of broiler kept with litter system for 42 days. Data were analyzed using a completely randomized design with five treatments and four replicates, consisted of 10 broilers in each replicates. The treatment diets were P1 = commercial feed, P2 = basal feed, P3 = basal feed + 3% sweet potato meal + 0.75% tape yeast (starter-finisher periode), P4 = basal feed + 3% sweet potato meal + 0.75% tape yeast (starter periode), P5 = basal feed + 3% sweet potato meal + 0.75% tape yeast (finisher periode). Variables observed were daily intake, body weight gain, final body weight, feed convertion, PER, water intake, carcass percentage, mortality, IOFCC, temperature and humidity. The result showed there is no effect on all cumulative performance of broiler. The best used sinbiotic on starter periode. IOFCC in treatment P4 were more profitable than the other treatments. Addtion of sinbiotic reduced mortality rates compared to commercial feed.

Judul: Metrik Einstein (Anti-) Self-Dual Berdimensi Empat dengan Metode Cartan
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.
