Judul: Digestive Organs, Total leukocytes, and Spleen Laying Period of Quail with BSF Maggot in Feed
Abstrak: Kualitas dan kuantitas pakan puyuh periode bertelur menjadi salah satu faktor penting yang harus diperhatikan untuk memaksimalkan produksi telur. Sumber protein pakan puyuh memiliki harga yang relatif mahal sehingga diperlukan sumber protein alternatif yang lebih murah seperti maggot. Akan tetapi belum diketahui dampak dari pemberian maggot BSF sebagai pakan terhadap organ pencernaan dan ketahanan tubuh puyuh periode bertelur. Penelitian ini bertujuan menganalisis ukuran organ pencernaan, limpa, dan total leukosit puyuh periode bertelur dengan pemberian maggot BSF dalam pakan. Penelitian ini menggunakan metode Uji-T dengan 2 perlakuan dan 5 ulangan untuk setiap perlakuan. Peubah yang diamati berupa persentase bobot dan panjang relatif organ pencernaan, persentase bobot limpa, serta total leukosit. Hasil penelitian menunjukkan ukuran organ pencernaan dan ketahanan tubuh pada puyuh periode bertelur yang diberi maggot BSF dan MBM tidak berbeda nyata (P<0,05) terhadap persentase bobot, panjang relatif pada organ pencernaan dan limpa serta total leukosit. Penggunaan maggot BSF dengan dosis 12% dalam pakan sebagai sumber protein utama tidak berdampak negatif terhadap kondisi organ pencernaan dan ketahanan tubuh., Quail is one type of poultry that has great potential in Indonesia. Feed is a very important factor that quail can produce eggs maximally. However, feed protein sources are expensive, so an alternative protein source needed is BSF maggots. The study aims to analyze the size of the digestive organs, spleen and total leukocytes of quail at the laying period that given BSF maggots in the feed. The parameters observed were the percentage of weight and relative length of the digestive organs, the percentage of spleen weight, and total leukocytes. This research used the T-test method with 2 treatments and 5 repetitions for each treatment. The variables observed were the percentage of weight and relative length of the digestive organs, the percentage of spleen weight, and total leukocytes. The results of the study showed that the size of the digestive organs and immunity organ of quail in the laying period given BSF maggots and MBM were not significantly different (P<0.05) in weight percentage, relative length of the digestive organs and spleen and total leukocytes. The use of BSF maggots at a dose of 12% in feed as the main protein source does not have a negative impact on the condition of the digestive organs and immunity organ.

Judul: Physiological Response and Performance of Quails During The Production Period with The Application of BSF Maggot Flour in Feed
Abstrak: Maggot BSF (Black Soldier Fly) memiliki kandungan protein yang tinggi, zat antimikroba, dan antijamur. Tepung maggot BSF dapat diberikan kepada puyuh sebagai sumber protein utama pakan. Sumber protein pakan komersial masih berasal dari impor, salah satunya meat bone meal (MBM). Alternatif menekan harga pakan digunakannya sumber protein lokal yang ketersedinya melimpah yaitu maggot BSF. Tujuan dari penelitian ini adalah untuk mengkaji respon fisiologis dan performa produksi puyuh dengan pemberian tepung maggot BSF dalam pakan. Penelitian menggunakan analisis uji-t dengan 2 perlakuan dan 5 kali ulangan, setiap ulangan terdiri dari 10 ekor puyuh periode produksi. Puyuh yang diberi perlakuan pakan mengandung sumber protein MBM dan maggot BSF tidak memberikan perbedaan pada respon fisiologis. Performa dalam aspek produksi konversi pakan dan mortalitas memiliki nilai yang lebih baik, dalam aspek ekonomi pakan mengandung sumber protein utama tepung maggot BSF memiliki nilai nilai IOFC lebih ekonomis dibandingkan pakan mengandung sumber protein utama MBM., BSF (Black Soldier Fly) maggot has a high protein content, anti-microbial and anti-fungal substances. BSF maggot meal can be given to quail as the main source of feed protein. Commercial feed protein sources still come from imports, one of which is meat bone meal (MBM). An alternative to reduce feed prices is the use of local protein sources that are abundant, namely BSF maggot. The purpose of this study was to assess the physiological response and production performance of quail by feeding BSF maggot meal. The study used t-test analysis with 2 treatments and 5 replicates, each replicate consisting of 10 quails in the production period. Quail treated with feed containing MBM and BSF maggot protein sources did not give differences in physiological responses. Performance in the production aspect of feed conversion and mortality has a better value, in the economic aspect, feed containing the main protein source of BSF maggot flour has a more economical IOFC value than feed containing the main protein source of MBM.

Judul: Penggunaan Metode Homotopi untuk Menyelesaikan Persamaan KdV (Korteweg-de Vries)
Abstrak: Natural phenomena can be explained using nonlinear mathematical models. In this paper, we studied the solution of KdV equation using the Homotopy method. The KdV equation is used for describing both surface and internal waves. One of the solutions is called a solitary wave. The use of homotopy method to solve the KdV equation required a nonlinear operator which was determined by the nonlinear form of the KdV equation itself. Based on this operator, a recursive formula was obtained to get a sequence of the KdV solution. The higher the sequence order of the sequence used, the closer to the exact solution of the KdV equation.
