Judul: Potency of Maggot Flour as a Substitute of Meat Bone Meal (Hermetia illucens) in Feed Formulation on Performance of IPB-D1 Chicken
Abstrak: Penelitian ini bertujuan untuk mengevaluasi kualitas konsentrat protein dari maggot sebagai alternatif meat bone meal pada ayam lokal IPB-D1 pada fase starter dan finisher. Penelitian ini menggunakan 300 ekor day old chick (DOC) ayam lokal IPB-D1 yang dipelihara selama 11 minggu dengan 3 perlakuan dan 10 ulangan. Rancangan percobaan yang digunakan adalah Rancangan Acak Lengkap (RAL) dengan perlakuan P1 = ransum mengandung 5% meat bone meal, P2 = ransum mengandung 5% maggot kontrol, dan P3 = ransum mengandung 5% deffated maggot. Peubah yang diukur adalah konsumsi pakan, bobot badan, pertambahan bobot badan, konversi pakan, mortalitas, dan income over feed and chick cost (IOFCC). Data di analisis dengan menggunakan sidik ragam (ANOVA) dan uji lanjut Duncan jika terdapat perbedaan nyata. Hasil penelitian menunjukkan pengaruh penggunaan 5% deffated maggot terhadap meningkatnya pertambahan bobot badan dan menurunkan konversi pakan. Simpulan penggunaan 5% deffated maggot dapat memperbaiki efisiensi pada pakan periode finisher, namun ransum dengan 5% maggot kontrol tidak berpengaruh terhadap performa ayam lokal IPB-D1 yang dipelihara selama 11 minggu., This study aims to evaluate the quality of protein concentrate from maggots as an alternative to meat bone meal in IPB-D1 local chickens in the starter and finisher phases. This study used 300 day old chicks (DOC) from local IPB-D1 chickens that were reared for 11 weeks with 3 treatments and 10 replications. The experimental design used was a completely randomized design (CRD), with treatment P1 = ration containing 5% meat bone meal, P2 = ration containing 5% maggot control, and P3 = ration containing 5% deffated maggot. The variables measured were feed consumption, body weight, body weight gain, feed conversion, mortality, and income over feed and chick cost (IOFCC). Data were analyzed using variance analysis (ANOVA) and Duncan's further test. The results showed the effect of using 5% deffated maggot on increasing body weight gain and reducing feed conversion. In conclusion, the use of 5% deffated maggot can improve efficiency in the finisher period feed, but the 5% control maggot ration has no effect on the performance of IPB-D1 local chickens reared for 11 weeks.

Judul: Percentage Carcass, Giblet, and Abdominal Fat of Broiler Chicken Given Maggot (Hermetia illucens) Meal on Feed
Abstrak: Hermetia illucens yang dikenal dengan nama Black Soldier Fly (BSF) atau maggot adalah insekta yang dapat menjadi sumber protein alternatif dalam pakan unggas. Penelitian ini dilakukan untuk mengetahui pengaruh pemberian tepung maggot (Hermetia illucens) pada pakan terhadap persentase dan bobot karkas, lemak abdominal, dan giblet yang dilaksanakan di Kandang B Fakultas Peternakan, Institut Pertanian Bogor, selama lima minggu. Metode yang digunakan adalah metode eksperimental menggunakan Rancangan Acak Lengkap (RAL) dengan empat perlakuan lima kali ulangan menggunakan 200 DOC. Setiap ulangan terdiri dari 10 ekor ayam broiler. Analisis data dilakukan dengan ANOVA kemudian jika ada perbedaan nyata pengaruh perlakuan maka dilanjut uji Duncan. Hasil penelitian menunjukan bahwa pemberian tepung maggot tidak berbeda nyata terhadap berat rempela tetapi berbeda sangat nyata (P<0,05) terhadap berat hidup, berat karkas, berat lemak abdominal, berat hati berat jantung, berat dada, berat punggung, berat sayap, berat paha atas, dan berat paha bawah. Berdasarkan hasil penelitian dapat disimpulkan bahwa pemberian tepung maggot pada pakan tidak dapat melebihi hasil dari perlakuan kontrol namun pemberian tepung maggot dalam pakan pada taraf 2,5% mampu memberikan hasil lebih baik dibandingkan dengan perlakuan pemberian tepung maggot pada taraf 5,0% dan 7.5%., Hermetia Illucens known by the name Black Soldier Fly (BSF) or Maggot is an insecta that can be used an alternative protein source in poultry feed. This study was aimed to determine the effect of Maggot (Hermetia illucens) flour in feed against the percentage of carcasses, abdominal fats, and giblets. This study carried out in the B cage Faculty of Animal Science, IPB University, for 5 weeks. The method used is an experimental method using Completely Randomized Design (CRD) with 4 treatments 5 replication was used in this study. This study used 200 DOC which every replication consist 10 broiler chickens. Data was analyzed using ANOVA and then if there is a real difference in treatment effect then futher tests were conducted using Duncan. The results showed that the provision of maggot meal is insignificant difference (p > 0.05) against the weight of a gizzard but significantly difference (P < 0.05) against the weight of life, weight of carcasses, severe abdominal fat, severe heart weight, chest weight, weight of the wings, wing weight, upper thigh weight, and lower thigh weight. Based on the results of the study can be concluded that the administration maggot meal in the feed can not exceed the results of the control treatment but the provision of a maggot meal in the feed at the level of 2.5% is able to provide optimum results compared to the treatment of the provision of the starch Maggot 5% and 7.5%.

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.
