Judul: EVALUATION OF PALM OIL BASED SILAGE ON THE PERFORMANCE OF LOCAL RAMS
Abstrak: Penelitian ini bertujuan mengevaluasi pengaruh pemberian silase berbasis pelepah sawit terhadap performa domba jantan lokal. Penelitian ini menggunakan domba jantan lokal sebanyak 15 ekor jenis ekor tipis yang berumur 4-5 bulan dengan bobot badan rata-rata 14 ± 0,9 kg yang dibagi menjadi 3 perlakuan dengan 5 ulangan. Perlakuan terdiri dari P0 : 70 % hijauan segar berbasis pelepah sawit + 30% bungkil inti sawit, P1 : 70% silase berbasis pelepah sawit + 30% bungkil inti sawit, P2 : 70% silase kering berbasis pelepah sawit + 30% bungkil inti sawit. Peubah yang diuji adalah konsumsi pakan, pertambahan bobot badan harian (PBBH), efisiensi pakan, dan Income Over Feed Cost (IOFC). Data dianalisis menggunakan Analysis of Varian (ANOVA) dan perlakuan yang berbeda nyata akan dilakukan dengan uji lanjut dengan Uji Duncan. Hasil penelitian menunjukkan bahwa perlakuan hijauan segar (P0) lebih baik dibandingkan silase (P1) dan silase kering (P2). Penelitian ini menyimpulkan bahwa pakan hijauan berbasis pelepah sawit yang diolah dengan silase maupun silase kering belum memberikan pengaruh terhadap performa domba jantan lokal., This study aimsed to evaluate the effect of giving palm frond-based silage on the performance of local rams. This study used 15 local rams aged 4-5 months with an average body weight of 14 ± 0.9 kg, divided into three treatments with five replications. The treatment consisted of P0 : 70% fresh forage based on palm fronds + 30% palm kernel cake, P1 : 70% silage based on palm fronds + 30% palm kernel cake, P2 : 70% dry silage based on palm fronds + 30% palm kernel cake. The variables tested were feed consumption, daily body weight gain (PBBH), feed efficiency, and Income Over Feed Cost (IOFC). Data were analyzed using Analysis of Variance (ANOVA), and Duncan's further test would carry out significantly different treatments. The results showed that the new forage treatment (P0) was better than silage (P1) and dry hay (P2). This study concluded that the processing of palm frond-based forage feed processed with silage or dried silage had not had an effect on the performance of local rams.

Judul: Fermented Feed Containing Sorgum and Indigofera on Male Sheep Performance
Abstrak: Pengaruh pemberian silase sorgum dan indigofera bernama Sorinfer dalam kadar yang berbeda terhadap performa domba lokal jantan. Penelitian dilakukan selama 7 minggu di kandang individu. Penelitian ini menggunakan 20 ekor domba jantan dewasa dengan bobot badan 20,90±3,72 kg. Domba dibagi menjadi 5 perlakuan dengan 4 ulangan terdiri dari P0 = 100% rumput lapangan (RL), P1 = 75% RL + 25% Sorinfer(S), P2 = 50% RL + 50% S, P3 = 25% RL + 75% S, P4 = 100% S. Uji Duncan digunakan jika ada perbedaan data menggunakan analisis varians ANOVA (Analyses of Variance) menggunakan software SPSS. Parameter yang diukur dalam penelitian ini adalah konsumsi nutrien pada pakan, pertambahan bobot badan harian, dan Income Over Feed Cost. Hasil penelitian menunjukkan bahwa perlakuan berpengaruh nyata (P<0,05) terhadap konsumsi bahan kering, pertambahan bobot badan harian, dan pendapatan terhadap biaya pakan. Kesimpulannya Sorinfer sampai dengan tingkat rasio 75% dapat meningkatkan asupan bahan kering, protein kasar, lemak kasar, serat kasar, pertambahan berat badan harian, dan Income Over Feed Cost., The effect of giving sorgum and indigofera silage named Sorinfer in different levels on the performance of males local sheeps. Research conducted over 7 weeks in their own cage. This research used 20 adult male sheeps, with body weight of 20.90±3.72 kg. The sheeps were divided into 5 treatments with 4 replicates consisted of P0 = 100% field grass (RL), P1 = 75% RL + 25% sorinfer (S), P2 = 50% RL + 50% S, P3 = 25% RL + 75% S, P4 = 100% S. Duncan test was used if there was a difference in the data using analysis of variance ANOVA (Analyses of Variance) using SPSS software. The parameters measured in this study were feed intake nutrient, daily weight gain, and income over feed cost. The treatment had a significant effect (P<0.05) of dry matter intake, daily weight gain, and income over feed cost. The conclusion is the sorinfer up to 75% level of ratio can increase intake of dry matter, crude protein, crude fat, crude fiber, daily weight gain, and income over feed cost.

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.
