Judul: Evaluation of Feeding Completer Wafers Containing Lamtoro Leaves-Cassava Leaves to Sheep
Abstrak: Legum dan limbah pertanian merupakan bahan yang dapat digunakan sebagai pengganti hijauan. Contoh leguminosa adalah daun lamtoro dan contoh limbah pertanian adalah daun singkong. Penelitian ini bertujuan untuk mengevaluasi kualitas pakan wafer yang mengandung lamtoro levaes-daun singkong dengan pemberian wafer dengan persentase yang berbeda. Penelitian ini menggunakan 5 perlakuan dengan 4 ulangan. Perlakuan yang diberikan adalah P0 = pakan konvensional (hijauan), P1 = pakan konvensional + 25% pakan wafer, P2 = pakan konvensional + 50% pakan wafer, P3 = pakan konvensional + 75% pakan wafer, P4 = 100% pakan wafer. Data dianalisis menggunakan ANOVA dan uji Duncan. Berdasarkan kualitas fisik yang dilihat dari kadar air, aktivitas air, densitas, dan daya tahan pakan wafer memiliki kualitas yang lebih baik. Kondisi fisiologis pada penelitian ini normal dilihat dari parameter suhu rektal, denyut jantung, dan pernapasan. Hasil percobaan menunjukkan bahwa perlakuan pakan berpengaruh terhadap (P<0,05) konsumsi pakan, pertambahan bobot badan, dan efisiensi pakan. Hasil penelitian menunjukkan bahwa pemberian pakan wafer akan meningkatkan konsumsi zat gizi BK, PK, SK, LK pakan domba. Pertambahan bobot badan terbaik pada pemberian pakan wafer dinyatakan oleh P3 dengan nilai 105,80 g ekor-1 hari-1. Hasil efisiensi pakan terbaik dari penelitian ini adalah P2 dengan nilai 7,40 % dan IOFC hasil terbaik adalah P4 dengan nilai Rp. 395.583, Legumes and agricultural waste are materials that can be used as substitutes for forage. An example of leguminosae is lamtoro leaves and an example of agricultural waste is cassava leaves. This study aimed to evaluate the quality of wafer feed containding lamtoro levaes-cassava leaves by feeding wafers with different percentages. This research used 5 treatments with 4 replications. The treatments given were P0 = conventional feed (forage), P1 = conventional feed + 25% wafer feed, P2 = conventional feed + 50% wafer feed, P3 = conventional feed + 75% wafer feed, P4 = 100% wafer feed. Data were analyzed using ANOVA and Duncan's test. Based on the physical quality as seen from the water content, water activity, density, and durability the wafer feed has better quality. The physiological condition on this research was normal as seen from the parameters of rectal temperature, heart rate, and respiration. The result of this experiment showed that feed treatments affected (P<0.05) consumption feed, body wight gain, and feed efficiency. The results of this research indicate that the giving of wafer feed will increase the consumption nutrient DM, CP, CF, EE of sheep feed. The best result of body wight gain that feeding wafers is trated by P3 with value of 105,80 g head-1 day-1 . The best result of feed efficiency from this research is P2 with value 7,40 % and best result IOFC is P4 with value Rp. 395.583.

Abstrak: Feed is an important aspect for productivity of livestock. Low quality feed can reduce the productivity of the livestock, so wafer of fed supplement is one of alternative. Wafer lamtoro supplement is one of the feed processing products that have high nutritional value that can help increase the production of livestock. This research aimed to assess the effect of wafer fed supplement on nutrient consumption and digestibility of local sheep rations. This research used Randomized Block Design with 4 treatments and 3 blocks as replicate and used 12 heads of local sheep with initial body weight 24.54±10.51 kg. Treatments were P0 = basal diet + 0% wafer of feed supplement (control); P1 = basal diet + 5% wafer of feed supplement; P2 = basal diet + 10% wafer of feed supplement; P3 = basal diet + 15% wafer of feed supplement. The Results showed that wafer fed supplement had significantly effect (p<0.05) for nutrient consumption, crude protein digestibility, final body weight and feed efficiency but not significant for dry matter digestibility, organic matter digestibility and crude fiber digestibility

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.
