Judul: Substitution of Soybean Meal with Black Soldier Fly Larvae Meal on Hematology and Blood Metabolite Profiles of Growing Lambs
Abstrak: Penelitian ini bertujuan untuk mengevaluasi pengaruh substitusi bungkil kedelai dengan Black soldier fly larvae meal terhadap profil metabolit darah dan hematologi domba fase pertumbuhan. Sebanyak 10 ekor domba ekor tipis yang terdiri dari 8 jantan dan 2 betina (berat awal 13,95 ± 3,07 kg) ditempatkan dalam kandang individu yang dilengkapi tempat untuk pakan dan air minum. Perlakuan yang digunakan adalah P1 = konsentrat starter bungkil kedelai 22% dan P2 = konsentrat starter bungkil kedelai 11% + 10% BSF larvae meal. Parameter yang diukur adalah hematologi (kadar hemoglobin, hematokrit, eritrosit, leukosit, diferensiasi leukosit yang terdiri dari persentase limfosit, monosit, neutrofil, eosinofil, dan basofil), dan metabolit darah (glukosa, kolesterol, protein total, dan albumin). Data dianalisis menggunakan independent sample T-test. Hasil penelitian menunjukkan bahwa konsentrat yang mengandung bsf larvae meal tidak berpengaruh nyata terhadap hematologi dan profil metabolit darah domba fase pertumbuhan. Substitusi bungkil kedelai 50% dengan black soldier fly larvae meal tidak mempengaruhi hematologi dan profil metabolit darah domba fase pertumbuhan.

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.
