Judul: Black Soldier Fly Maggot Nutrient Composition Using Faeces Growing Media and Animal Feed Leftovers
Abstrak: Penelitian ini bertujuan mengetahui kandungan nutrien maggot black soldier fly (BSF) menggunakan media limbah peternakan ayam petelur, kambing, dan sapi. Penelitian ini menggunakan rancangan acak kelompok dengan 3 perlakuan dan 3 ulangan. Perlakuan A (feses ayam petelur dan dedak padi), B (feses kambing dan sisa pakannya berupa rumput lapang) dan C (feses sapi dan sisa pakannya berupa rumput gajah). Parameter yang diamati adalah performa maggot, kadar air, bobot populasi, suhu, dan kelembaban. Data dianalisis menggunakan uji Analisis of Variance (ANOVA) dengan uji lanjut Duncan. Hasil penelitian menunjukkan bahwa perlakuan A berbeda nyata (P<0,005) dibandingkan dengan perlakuan lainnya untuk parameter bobot, kadar air, dan panjang. Populasi terbanyak didapatkan pada perlakuan A. Suhu yang optimal bagi pertumbuhan maggot adalah 30oC dan kelembaban yang diukur dengan kadar air berkisar antara 70%-80%. Kandungan nutrien maggot tertinggi didapatkan pada maggot perlakuan B. Kesimpulannya media maggot perlakuan A memiliki pengaruh performa yang lebih tinggi daripada media lain., This study aimed to determine the nutrient content of black soldier fly (BSF) maggot using the waste media of laying hens, goats and cows. This study used a randomized block design with 3 treatments and 3 replications. Treatments A (laying chicken faeces and rice bran), B (goat feces and grass residue) and C (cow feces and elephant grass residue). Parameters observed were Maggot performance, moisture content, population weight, temperature and humidity. Data were analyzed using the Analisis of Variance (ANOVA) test with Duncan's further test. The results showed that treatment A was significantly different (P<0.005) compared to other treatments for the parameters of weight, moisture content and length. The largest population was found in treatment A. The optimal temperature for maggot growth was 30oC and humidity as measured by water content ranges from 70%- 80%. Maggot with treatment B had the highest nutrient content. In conclusion, maggot media treatment A had a higher performance effect than other media.

Judul: Productivity of Maggot Black Soldier Fly on Different Live Media
Abstrak: Maggot merupakan larva dari lalat black soldier fly yang mengandung nutrisi yang cukup tinggi sehingga dapat dijadikan sebagai pakan alternatif bagi ternak. Budidaya maggot dapat dilakukan dengan menggunakan media yang mengandung bahan organik. Pemilihan media harus memperhatikan kandungan nutrisi yang dikandungnya karena berpengaruh terhadap produktivitas maggot yang dihasilkan. Penelitian ini bertujuan menganalisis produktivitas maggot dengan pengaruh media hidup yang berbeda. Penelitian ini menggunakan rancangan acak lengkap (RAL) dengan 3 perlakuan dan 4 ulangan dengan uji lanjut Duncan. Media yang diguanakan yaitu limbah rumah makan, ampas kelapa dan dedak padi. Peubah yang diamati adalah bobot, panjang, suhu media, kelembaban media dan pH media. Hasil penelitian menunjukkan bahwa penggunaan media hidup yang berbeda berpengaruh nyata (P<0,05) terhadap produktivitas maggot. Penggunaan media limbah rumah makan menghasilkan bobot maggot sebesar 3,07 kg dan panjang maggot 1,90 cm. Penggunaan media ampas kelapa menghasilkan bobot maggot sebesar 2,42 kg dan panjang maggot 1,40 cm. Penggunaan media dedak padi menghasilkan bobot maggot sebesar 2,05 kg dan panjang maggot 1,08 cm., Maggot is the larvae of the black soldier fly which contains high enough nutrients so that it can be used as an alternative feed for livestock. Maggot cultivation can be done using media containing organic matter. The selection of media must pay attention to the nutritional content it contains because it affects the productivity of the maggot produced. This study aims to analyze the productivity of maggot with the influence of different live media. This study use a completely randomized design (RAL) with 3 treatments and 4 replications with Duncan’s further test. The media used were restaurant waste, coconut dregs and rice bran. The observed variables were maggot weight, length, media temperature, media humidity and media pH. The results showed that the use of different live media had a significant (P<0,05) effect to maggot productivity. The use of restaurant waste media produces a maggot weight of about 3,07 kg and a maggot length of about 1,90 cm. The use of coconut dregs media resulted in a maggot weight of about 2,42 kg and a maggot length of about 1,40 cm. The use of rice bran media produces in a maggot weight of about 2,05 kg and a maggot length of about 1,08 cm.

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.
