Judul: Evaluation of Giving Maggot BSF (Black Soldier Fly) to the Internal Organs and Digestive Tract of Lohmann Brown Strain Laying Hens
Abstrak: Penelitian ini bertujuan mengevaluasi pengaruh pemberian maggot BSF terhadap organ dalam dan saluran pencernaan ayam petelur strain Lohmann Brown. Penelitian ini menggunakan rancangan acak lengkap (RAL) dengan 3 perlakuan dan 5 ulangan, setiap ulangan terdiri atas 10 ekor ayam. Ransum perlakuan yang digunakan yaitu P0 = ransum kontrol (maggot BSF 0%); P1 = ransum menggunakan maggot BSF 6,7%; P2 = ransum menggunakan maggot BSF 13%. Peubah yang diamati yaitu persentase bobot organ dalam dan persentase bobot serta panjang relatif saluran pencernaan. Data hasil penelitian dianalisis menggunakan analisis ragam (ANOVA) dan jika terdapat hasil yang berbeda nyata (P<0,05) diuji lanjut dengan uji Tukey. Hasil penelitian menunjukkan bahwa pemberian maggot BSF berpengaruh nyata (P<0,05) menurunkan persentase bobot pankreas dan meningkatkan persentase bobot duodenum dan kolon. Kesimpulan dari penelitian ini adalah pemberian maggot BSF kering dapat mempengaruhi organ dalam dan saluran pencernaan. Pemberian maggot BSF 13% menurunkan persentase bobot pankreas, meningkatkan persentase bobot duodenum dan kolon ayam petelur strain Lohmann Brown., This study aimed to evaluate the effect of BSF maggot supplementation on the internal organs and digestive tract of Lohmann Brown laying hens. The study used a completely randomized design (CRD) with 3 treatment and 5 replications with 10 hens per replication. The treatment diets used were P0 = control diet (0% BSF maggot); P1 = diet with 6.7% BSF maggot; P2 = diet with 13% BSF maggot. The variables observed were the percentage of internal organ weight and the percentage of weight and relative length of the digestive tract. The data were analyzed using analysis of variance (ANOVA) and if significant differences were found (P<0,05), Tukey's test was performed for further analysis. The results indicated that the supplementation of BSF maggots significantly (P<0,05) reduced the percentage of pancreatic weight, increased the percentage of duodenum weight and colon weight. In conclusion, the provision of dried BSF maggots affected the internal organ and digestive tract. The supplementation of 13% BSF maggots decreased in the percentage of pancreatic weight, an increased in the percentage of duodenum weight and colon weight in Lohmann Brown laying hens.

Judul: Evaluation of Feeding Maggot Black Soldier Fly on Reproductive Tract and Egg Yolk Follicles of Lohmann Brown Strain
Abstrak: Penelitian ini bertujuan mengevaluasi pengaruh pemberian maggot Black Soldier Fly terhadap saluran reproduksi dan folikel kuning telur ayam petelur strain Lohmann Brown. Rancangan percobaan yang digunakan adalah rancangan acak lengkap (RAL) dengan 3 perlakuan dan 5 ulangan dengan 10 ekor ayam per ulangan. Ransum perlakuan yang digunakan pada penelitian ini adalah: P0 = ransum menggunakan maggot BSF 0%, P1 = ransum menggunakan maggot BSF 6,7%, P2 = ransum menggunakan maggot BSF 13%. Peubah yang diukur adalah panjang dan bobot saluran reproduksi, jumlah dan bobot folikel kuning telur. Data penelitian dianalisis menggunakan analisis varian (ANOVA) dan jika ada hasil penelitian yang signifikan (P<0,05) diuji lanjut dengan uji Tukey. Hasil penelitian menunjukkan bahwa pemberian maggot BSF signifikan (P<0,05) menurunkan jumlah folikel putih besar, tetapi perlakuan pakan tidak berpengaruh pada peubah-peubah lainnya. Kesimpulan dari penelitian ini adalah pemberian maggot BSF kering hingga taraf 13% tidak mempengaruhi saluran reproduksi dan folikel kuning telur, tetapi menurunkan jumlah folikel putih besar dan pemberian 6,7% mampu meningkatkan persentase jumlah folikel kuning telur ayam petelur strain Lohmann Brown., This study aims to evaluate the effect of feeding maggot Black Soldier Fly on the reproductive tract and egg yolk follicles of Lohmann Brown strain laying hens. The experimental design used in this study was a completely randomized design (CRD) with 3 treatments and 5 replications with 10 chickens per replication. The treatment diets used in this study were: P0 = diet using maggot BSF 0% (control), P1 = diet using maggot BSF 6.7%, and P2 = diet using maggot BSF 13%. The variables measured were the length and weight of the reproductive tract, the number and weight of yolk follicles. The data were analyzed using analysis of variance (ANOVA), and if there was any significant result (P<0.05) were further tested using Tukey test. The results showed that feeding maggots BSF significantly (P<0.05) reduced the number of large white follicles, but the treatment had no effect on other variables. The conclusion of this study was that feeding dry maggot BSF up to 13% did not affect the reproductive tract and yolk follicles, but decreased for the number of large white follicles and feeding dry maggot BSF 6.7% was able to increase the percentage of the number of yolk follicles in laying hens of the Lohmann Brown strain.

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.
