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: 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: : Persamaan Tunggal sebagai Representasi Kurva Komposit
Abstrak: A mathematical method is introduced to represent a composite curve based on an extension of analytic geometry. The representation is given either with a single equation or with two equations, in the case of parametric representation. This method permits the representation of composite curves in similar manner to the conventional representation of non-composite curves. Some mathematical tools, including Heaviside unit step function and periodizer function, are used in the establishment of a single equation. In this paper, regular equations of regular and irregular polygon, as well as composite curves of two dimensions, are implemented using a computer algebraic system, Mathematica.
