Judul: Characteristics of Carcass and Non Carcass which were Given Maggot Black Soldier Fly Flour in Feed
Abstrak: Pakan merupakan salah satu faktor penting yang menunjang produktivitas puyuh. Salah satu sumber protein pakan yang biasanya digunakan dalam pakan puyuh adalah Meat Bone Meal (MBM). MBM merupakan produk impor sehingga menyebabkan harganya mahal. Alternatif untuk menggantikan MBM salah satunya dengan memanfaatkan bahan pakan lokal yaitu maggot black soldier fly. Penelitian ini bertujuan mengkaji karakteristik karkas dan non karkas puyuh yang diberi tepung maggot black soldier fly dalam pakan. Peubah yang diamati meliputi bobot potong, bobot dan persentase karkas, bobot dan persentase non karkas, bobot dan persentase potongan komersial karkas serta bobot dan persentase karkas edible dan non edible. Puyuh yang digunakan yaitu puyuh betina periode bertelur umur 44-50 minggu. Prosedur penelitian terdiri dari pemeliharaan dan pembuatan tepung maggot black soldier fly, pembuatan pakan, persiapan kandang dan pemeliharaan, penyembelihan, serta parting dan deboning. Perlakuan yang diberikan yaitu R0 (pakan mengandung sumber protein utama MBM) dan R1 (pakan mengandung sumber protein utama maggot black soldier fly. Data yang diperoleh dianalisis menggunakan uji-t dua sampel. Hasil penelitian menunjukkan bahwa puyuh yang diberikan pakan mengandung sumber protein utama tepung maggot black soldier fly menghasilkan karakteristik karkas dan non karkas yang tidak berbeda dengan puyuh yang diberikan pakan mengandung sumber protein utama MBM., Feed is one of the important factors that support quail productivity. One of the sources of feed protein that is usually used in quail feed is Meat Bone Meal (MBM). MBM is an imported product, causing it to be expensive. One of the alternatives to replace MBM is by utilizing local feed ingredients, namely black soldier fly maggots. This study aims to examine the characteristics of quail carcasses and non-quail carcasses fed with black soldier fly maggot flour in feed. The observed variables include cut weight, carcass weight and percentage, noncarcass weight and percentage, carcass commercial cut weight and percentage and edible and non-edible carcass weight and percentage. The quail used is a female quail with an egg-laying period of 44-50 weeks of age. The research procedure consists of maintenance and manufacturing of black soldier fly maggot flour, feed making, cage preparation and maintenance, slaughter, as well as parting and deboning. The treatment given was R0 (feed containing the main source of protein MBM) and R1 (feed containing the main source of black soldier fly maggot protein). The data obtained were analyzed using a two-sample t-test. The results of the study showed that quails fed containing the main source of protein black soldier fly maggot flour produced carcass and non-carcass characteristics that were no different from quails fed containing the main source of MBM protein.

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: Hamiltonian formulation for linear waves motion in two layers fluid
Abstrak: The surface wave could be considered as a wave that separates two fluids, namely water and air. Based on this assumption, it is introduced the interfacial wave, a wave between two layers of fluid with different density. The formulation of interfacial waves motion begins with deriving the base equation of irrotational ideal fluid. Furthermore, according to irrotational fluid assumption, the base equation can be stated in velocity potential. In this derivation, the fluids domain is assumed to be restricted by rigid lid boundary conditions, both at the upper and lower limit. Therefore, the interfacial waves motion can be explained in a hamiltonian formulation. In the hamiltonian formulation, total energy is defined as the sum of kinetic and potential energy. The hamiltonian system is obtained from reduction of kinetic energy by using the Dirichlet Neumann Operator. The resulted kinetic energy equation is nonlinear. Therefore, this form is linearized by first part of the Taylor expansion. This linearization gives a dispersion relation of linear wave. Based on this dispersion relation, the phase speed of the linear wave depends on the density ratio of the two layers fluid.
