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: Hematological Value off Egg-Laying Period of Quail with BSF  Maggot in Feed
Abstrak: Puyuh (Coturnix coturnix japonica) merupakan salah satu komoditas unggas dengan produk yang dapat dihasilkan berupa daging dan telur. Faktor penting yang mempengaruhi produktivitas puyuh adalah pakan. Harga pakan komersial semakin mahal khususnya pakan sumber protein, maka diperlukan pakan alternatif yaitu maggot BSF. Penelitian ini bertujuan menganalisis penambahan tepung maggot BSF sebagai pada puyuh sumber protein alternatif terhadap aspek hematologi. Penelitian ini menggunakan metode rancangan acak lengkap (RAL) dengan dua perlakuan dan lima ulangan untuk setiap perlakuan. Peubah yang diamati meliputi sel darah merah (jumlah eritrosit, hemoglobin, hematokrit, indeks eritrosit) dan sel darah putih (total leukosit, diferensiasi leukosit yang terdiri atas limfosit, heterofil, monosit, eosinofil, dan basofil), serta rasio H/L sebagai indeks stres. Hasil penelitian menunjukkan bahwa perlakuan pemberian maggot BSF sebanyak 12% menghasilkan nilai hemoglobin sedikit lebih tinggi daripada pemberian pakan MBM dan dihasilkan tingkat ketahanan tubuh yang sama baiknya antara kedua perlakuan. Oleh karena itu, puyuh periode bertelur yang diberi pakan maggot BSF dan MBM sebagai sumber protein utama menghasilkan nilai hematologi yang hampir sama., Quail (Coturnix coturnix japonica) is one of the poultry commodities with products that can be produced in the form of meat and eggs. An important factor that influences quail productivity is feed.The price of commercial feed is increasingly expensive, especially protein source feed, so alternative feed is needed, namely BSF maggots. Penelitian ini bertujuan menganalisis penambahan tepung maggot BSF sebagai pada puyuh sumber protein alternatif terhadap aspek hematologi. This study used a completely randomized design (CRD) method with two treatments and five replications for each treatment. The variables observed include red blood cells (number of erythrocytes, hemoglobin, hematocrit, erythrocyte index) and white blood cells (total leukocytes, leukocyte differentiation consisting of lymphocytes, heterophils, monocytes, eosinophils and basophils), as well as the H/L ratio as an index. stress in quail. The results of the research showed that the treatment with 12% BSF maggots produced slightly higher hemoglobin values than the MBM feed and resulted in the same level of body resistance between the two treatments. Therefore, quail during the laying period that were fed maggot BSF and MBM as the main protein source produced almost the same hematological values.

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.
