Judul: Substitusi Bungkil kedelai dengan Tepung Jangkrik pada Ransum Domba Jantan Muda terhadap Gambaran Hematologi dan Metabolit Darah.
Abstrak: The aim of this study was to evaluate the effect of subtitution of soybean meal by cricket meal on nutrient consumption, hematology and blood metabolites of growing lamb. This study used complete randomized block design, with 3 treatments and 4 replications. Twelve growing lamb in 2-4 month of age and average of body weight 10.36±1.62 kg, were divided into R1: concentrate containing soybean meal, R2: concentrate containing soybean meal and cricket meal, R3: concentrate containing cricket meal and all animals fed 40% of Brachiaria humidicola and 60% concentrate. Data were analyzed using ANOVA with parameters: nutrient consumption, hematology (hemoglobin, hematocrit, eritrosito, leukosit and differensial leukosit) and blood glucose and protein. The relationship between the consumption of carbohydrates with blood glucose levels following the equation Y = 0.0054X2 – 2.38X + 318.5 and the relationship between the protein consumption with blood protein of following equation Y = 0.016X2 – 1.802X + 56.032. The results showed that the treatments did not significant affect on nutrient consumption, hemoglobin, erythrocyte, leukocytes, leukocyte differentiation and glucose. It was concluded that soybean meal can be substituted by crickets meal for growing lamb without any problem with palatability and health status.

Judul: Subtitution of Soybean Meal With Defatted Black Soldier Larvae Meal in Starter Concentrate on Performance of Lamb
Abstrak: Penelitian ini bertujuan substitusi bungkil kedelai dengan defatted Black Soldier Fly larvae meal pada konsentrat starter terhadap performa domba fase pertumbuhan. Penelitian ini menggunakan 10 ekor anak domba fase pertumbuhan umur 5 bulan dengan bobot badan 13,95±3,07 kg dan ditempatkan pada kandang individu. Domba dibagi menjadi 2 perlakuan yaitu P1 = konsentrat starter mengandung 22% bungkil kedelai + hijauan, P2 = konsentrat starter mengandung (11% bungkil kedelai + 10% defatted BSF larvae meal) + hijauan. Parameter yang diukur dalam penelitian ini adalah konsumsi nutrien (konsumsi bahan kering, konsumsi protein kasar, konsumsi lemak kasar, konsumsi serat kasar, konsumsi bahan ekstrak tanpa nitrogen dan konsumsi total digestible nutrient), pertambahan bobot badan harian, efisiensi pakan dan income over feed cost. Data dianalisis menggunakan Uji-T (Independent Sample T-Test). Hasil penelitian menunjukkan bahwa penambahan defatted BSF larvae meal tidak berpengaruh nyata terhadap konsumsi nutrien, pertambahan bobot badan harian, efisiensi pakan dan income over feed cost (IOFC)., This research aimed to determine the substitution of soybean meal with defatted Black Soldier Fly larvae meal in starter concentrate on performance of lamb in growth phase. A total of 10 growing lambs were used in this study (5 months, 13.95±3.07 kg). The lambs were divided into 2 treatments, name up P1 = starter concentrate containing 22% soybean meal + forage, P2 = starter concentrate containing 11% soybean meal + 10% defatted BSF larvae meal + forage. The parameters measured were nutrient intake (dry matter intake, crude protein intake, crude fat intake, crude fiber intake, nitrogen free extract intake and total digestible nutrient intake), average daily gain, feed efficiency, and income over feed cost. The data were analyzed using Independent Sample T-Test. The results showed that the substitution of soybean meal with defatted Black Soldier Fly (BSF) larvae meal did not significantly affect (P>0,05) nutrient intake, average daily gain, feed efficiency and income over feed cost (IOFC).

Judul: Persamaan Gelombang Permukaan Dalam Sistem Hamiltonian
Abstrak: Fluida adalah suatu zat yang bentuknya dapat berubah secara kontinu akibat gaya geser. Dua bentuk fluida yang dikenal adalah fluida yang berbentuk cairan dan gas. Dalam tulisan ini akan dibahas fluida yang berbentuk cairan. Persamaan yang memodelkan fenomena gelombang fluida di antaranya adalah sistem Hamiltonian. Persamaan ini berasumsi babwa fluida dalam keadaan ideal di mana fluida tak mampu mampat (inkompresibel), fluida tak rotasional (irrotasional).
