Judul: THE EFFECT OF GIVING A FEED ADDITIVE CONTAINING MEAL AND BLACK SOLDIER FLY OIL ON PERFORMANCE IN WEANED LAMBS
Abstrak: Penelitian ini bertujuan untuk mengetahui pengaruh pemberian pakan tambahan dengan metode creep feeding yang mengandung tepung dan minyak maggot (Black Soldier Fly) terhadap performa anak domba lepas sapih. Penelitian ini menggunakan 10 ekor anak domba lepas sapih umur ± 2-3 bulan, dengan bobot badan 8,04 ± 0,78 kg dan ditempatkan pada kandang individu. Domba dibagi menjadi 2 perlakuan yaitu P1 = Konsentrat Komersial + hijauan, P2 = Konsentrat tambahan dengan penambahan tepung dan minyak Black Soldier Fly + 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 nutrien), pertambahan bobot badan harian, dan efisiensi pakan. Data dianalisis menggunakan Uji-T (Independent Sample T-Test). Hasil penelitian menunjukkan bahwa penambahan tepung dan minyak Black Soldier Fly berpengaruh nyata (P<0,05) dalam menaikkan konsumsi bahan kering, protein kasar, dan total digestible nitrogen, tetapi tidak berpengaruh nyata (P>0,05) menaikkan konsumsi lemak kasar, serat kasar, BETN, pertambahan bobot badan harian, dan efisiensi pakan., This research aimed to determine the effect of giving a feed additive with the creep feed method containing meal and maggot oil (Black Soldier Fly) on the performance in weaned lambs. This research used 10 post-weaning lambs aged ± 2-3 months, with body weight of 7,54 ± 0,78 kg and placed in individual cages. The lambs were divided into 2 treatments consisted of P1 = Commercial concentrate + forage, P2 = Black Soldier Fly concentrate with the addition of meal and Black Soldier Fly oil + forage. The parameters measured in this study were nutrient consumption (dry matter intake, crude protein intake, crude fat intake, crude fiber intake, nitrogen free extract and total digestible nutrient consumption), daily weight gain, and feed efficiency. The data were analyzed using T-Test (independent sample T-Test). The results showed that the treatment had a significant effect (P<0,05) on consumptions of dry matter, crude protein, and total digestible nitrogen. There were not effect (P>0,05) of crude fat, crude fiber, N-free extract intake, daily weight gain, and feed efficiency.

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: Penggunaan Teorema Homeomorphy 2-Manifold dan Teorema Euler Poincare pada Torus 𝑇�� dan Simplicial Complex 𝐾��
Abstrak: Two dimensional topological spaces are said to be homeomorphic if they have the same topological invariant, where one of topological invariant used is an Euler characteristic. Homeomorphy 2-Manifold’s Theorem and Euler Poincare’s Theorem are used to distinguish two topological spaces. Homeomorphy 2-Manifold’s Theorem uses Euler characteristic to identify two dimensional topological spaces. Euler Poincare’s Theorem is an alternative way to find Euler characteristic with Betti number, which is topological invariant as well. The objective of this paper is to investigate the homeomorphism of torus 𝑇����� and simplicial complex 𝐾�����. Topological space torus and simplicial complex 𝐾����� have the same Euler characteristic, which is two. Based on Homeomorphy 2-Manifold’s Theorem topological space torus 𝑇����� and simplicial complex 𝐾����� is homeomorphic.
