Judul: Evaluation of Probiotic Addition of Lactic Acid Bacteria from Black Soldier Fly Maggots Against on the Performance and Blood Profile of Broiler Chickens
Abstrak: Penelitian ini dilakukan untuk mengevaluasi pengaruh penambahan probiotik bakteri asam laktat asal maggot BSF terhadap performa dan profil darah ayam broiler. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan 3 perlakuan, 5 ulangan, setiap ulangan menggunakan 10 ekor. Perlakuan terdiri atas P1= ransum basal (kontrol) + placebo, P2= ransum basal + 106 cfu bakteri asam laktat per gram pakan, P3= ransum basal + 107 cfu bakteri asam laktat per gram pakan. Hasil sidik ragam menunjukkan bahwa pemberian probiotik 106 dan 107 cfu bakteri asam laktat per gram pakan nyata (P<0,05) menurunkan performa fase starter dan jumlah leukosit namun tidak mempengaruhi profil darah dan performa fase grower, finisher, serta selama 28 hari pada ayam broiler. Simpulan dari penelitian ini adalah pemberian probiotik bakteri asam laktat (BAL) asal maggot Black Soldier Fly dengan dosis 106 dan 107 cfu per gram pakan menurunkan performa ayam pada periode starter, tetapi dapat memperbaiki performa ayam pada fase grower, finisher dan selama 28 hari pemeliharaan., This research was conducted to evaluate the effect of the addition of probiotic lactic acid bacteria from BSF maggots on the performance and blood profile of broiler chickens. This study used a Completely Randomized Design with 3 treatments, 5 replications, each replication consist of 10 heads. The treatments consisted of P1= basal ration (control) + placebo, P2= basal ration + 106 cfu of lactic acid bacteria per gram of feed, P3= basal ration + 107 cfu of lactic acid bacteria per gram of feed. The results showed that the addition of probiotics at 106 and 107 cfu of lactic acid bacteria per gram of feed decreased (P<0.05) the performance of starter phase broiler chickens and the number of leukosit but did not show a significant difference of the blood cells profile and performance of the grower, finisher, and cumulative for 28 days. The conclusion of this research was that the addition of lactic acid bacteria probiotics from black soldier fly maggots at doses of 106 and 107 cfu per gram of feed decreased performance in the starter period, but it can improve chicken performance at grower, and finisher periods as well as the cumulative performance for 28 days.

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.
