Judul: Evaluation of Probiotic Administration of Black  Soldier Fly Larvae (BSF) on Internal Organs and Blood Hematology of Broiler  Chickens
Abstrak: Penelitian ini bertujuan untuk mengevaluasi pemberian suplementasi probiotik terhadap persentase bobot organ dalam, panjang relatif organ dalam, dan bobot organ imunitas broiler. Rancangan yang digunakan dalam penelitian adalah rancangan acak lengkap (RAL) dengan 5 perlakuan dan 5 ulangan, masing-masing ulangan berisi 10 ekor broiler. Perlakuan penelitian broiler terdiri dari P0 = pakan kontrol tanpa probiotik, P1 = pakan kontrol + 1 ml L-1 probiotik komersial, P2 = pakan kontrol + 1 ml L-1 probiotik larva BSF, P3 = pakan kontrol + 3 ml L-1 probiotik larva BSF, P4 = pakan kontrol + probiotik larva BSF 5 ml L-1. Peubah yang diamati adalah persentase organ dalam, persentase organ imunitas, persentase panjang relatif saluran pencernaan, dan hematologi darah. Hasil analisis evaluasi probiotik larva black soldier fly perlakuan (P4) dengan dosis 5 ml L-1 dapat memperbaiki organ empedu dan panjang relatif organ duodenum. Perlakuan (P1) dengan dosis 1 g L-1 dapat memperbaiki hematologi darah ditunjukkan pada peubah limfosit dan heterofil yang rendah.

Judul: Utilization of Liquid Probiotics from Fermentation  Black Soldier Fly Larvae (Hermetia illucens) on Performance Broiler
Abstrak: Penelitian ini bertujuan mengevaluasi penggunaan probiotik cair asal fermentasi larva black soldier fly (BSF) terhadap performa ayam broiler. Sebanyak 250 ekor broiler jantan strain Cobb CP 707 dibagi kedalam 5 perlakuan dan 5 ulangan menggunakan rancangan acak lengkap. Perlakuan terdiri dari P0 = Pakan broiler + air minum tanpa probiotik, P1 = Pakan broiler + air minum (1 ml L-1 probiotik komersil), P2 = Pakan broiler + air minum (1 ml L-1 probiotik asal fermentasi larva BSF), P3 = Pakan broiler + air minum (3 ml L-1 probiotik asal fermentasi larva BSF), dan P4 = Pakan broiler + air minum (5 ml L-1 probiotik asal fermentasi larva BSF). Hasil penelitian menunjukkan probiotik asal fermentasi larva BSF tidak berbeda nyata (P>0,05) terhadap performa broiler. Income over feed and chick cost (IOFCC) yang dihasilkan P4 lebih efisien dalam menghemat biaya pakan dan menghasilkan indeks performa tertinggi selama pemeliharaan dibandingkan perlakuan lainnya. Berdasarkan hasil tersebut diketahui bahwa penggunaan probiotik cair asal fermentasi larva BSF dalam air minum pada penelitian ini belum memberikan pengaruh yang signifikan terhadap performa ayam broiler namun masih dapat menguntungkan berdasarkan perhitungan IOFCC dan indeks performa dibandingkan perlakuan tanpa probiotik., This research aimed to evaluate the use of liquid probiotics from fermentation black soldier fly (BSF) larvae on performance broilers. A total of 250 male broilers strain Cobb CP 707 were divided into 5 treatments and 5 replications using a completely randomized design. The treatment in this study consisted of P0 = broiler feed + water without probiotics, P1= Broiler feed + water with 1 ml L-1 commercial probiotic, P2 = Broiler feed + water with 1 ml L-1 probiotics from fermentation BSF larvae, P3 = Broiler feed + water with 3 ml L-1 probiotics from fermentation BSF larvae, and P4 = Broiler feed + water with 5 ml L-1 probiotics from fermentation BSF larvae. The results showed that the use of probiotics from fermentation BSF larvae was not significantly different (P>0.05) on broiler performance. IOFCC produced using P4 is more efficient in saving feed cost and the highest performance index during maintenance compared to other treatments. Based on the results, it can be seen that the use of liquid probiotics from fermentation BSF larvae in drinking water in this study was not been significant effect on broiler performance however can be advantageous based on IOFCC calculations and performance index compared to without probiotics.

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.
