Judul: Profil dan Kolesterol Darah Domba Lokal yang Mendapat Ransum yang Mengandung Sabut Kelapa Sawit Hasil Fermentasi dengan Pleurotus ostreatus.
Abstrak: Palm press fiber (PPF) can be used as an alternative forage for ruminants. The aim of this experiment was to evaluate the nutritive value of PPF fermented by Pleurotus ostreatus and to evaluate the potency of the fermented PPF (PPFm) to replace elephant grass as a component of ration for rams. A randomized block design experiment was used to allocate randomly three experimental rations into four groups of twelve rams. Rams have an average of initial life weight of 23.32 ± 1.68 kg. The experimental rations consisted of R0 = 30% elephant grass (EG) +70% concentrate (control), R1= 15% EG + 15% PPFm + 70% concentrate and R2= 30% PPFm + 70% concentrate. Dry matter consumption, digestibility, blood profile and blood cholesterol were observed. The results showed that there were no differences in dry matter consumption, digestibility, blood profile and blood cholesterol of rams, except the leukocytes count showed a decrease with increasing number of additions PPFm in the ration (P<0.05). It was concluded that fermentation using Pleurotus ostreatus increased the nutritive value of PPF and the inclution of 30 % PPFm in the ration of rams could replace the elephant grass, can increase the immunity of rams characterized by increasing levels of blood lymphocytes to 22%, which is supported by increase in the metabolic performance of rams. The use of PPFm in the ration of 15% more efeective in lowering blood cholesterol sheep to 27,04%.

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: Closed Knight’s Tour pada Papan Catur Berbentuk Persegi Panjang dengan Ukuran Maksimal 8 × 8
Abstrak: Closed Knight’s Tour merupakan langkah kuda yang mengunjungi setiap kotak pada papan catur tepat satu kali dengan langkah kuda berawal dan berakhir pada kotak yang sama. Graf yang terbentuk dari closed knight’s tour dinotasikan sebagai graf G(m,n), dengan m adalah banyaknya baris dan n adalah banyaknya kolom. Graf tersebut memuat Hamiltonian cycle. Sebuah graf terhubung G adalah graf bipartite jika dan hanya jika graf tersebut tidak memiliki cycle dengan panjang ganjil. Papan catur yang memenuhi syarat cukup untuk memiliki closed knight’s tour adalah papan catur berukuran 5 × 6, 5 × 8, 6 × 6, 6 × 7, 6 × 8, 7 × 8, dan 8 × 8.
