Judul: External Quality of Silver Brakel Kriel Egg by  Giving Mealworm Meal as Supplement Feedstuff
Abstrak: Ayam arab silver adalah jenis ayam petelur yang dikenal memiliki efisiensi pakan yang baik dan performa bertelur yang tinggi. Kualitas telur ayam arab silver dapat ditingkatkan dengan memberikan pakan yang kaya nutrien. Ulat hongkong adalah serangga yang tersebar di seluruh dunia. Ulat hongkong dapat digunakan secara komersial sebagai pengganti sumber protein konvensional, karena diketahui mengandung tinggi protein kasar, lemak, termasuk omega-3 dan 6. Penelitian dilakukan untuk menganalisis kualitas eksternal telur ayam arab silver yang diberi tepung ulat hongkong sebagai bahan pakan suplementasi. Penelitian ini menggunakan 36 telur dari ayam arab silver berusia 30-34 minggu, yang dibagi menjadi 2 perlakuan, dengan 6 ulangan dan 3 telur tiap ulangan. Kualitas eksternal telur diuji dua kali, pada minggu kedua dan keempat. Ransum perlakuan terdiri dari P0 = 100% ransum kontrol dan P1 = ransum yang mengandung 4% ulat hongkong. Data dianalisis menggunakan metode Uji T independen. Analisis data menunjukkan adanya peningkatan dalam kualitas eksternal telur, pada warna kuning telur dan persentase bobot kerabang. Penambahan 4% tepung ulat hongkong tidak mempengaruhi indeks telur, berat telur, Haugh unit, berat kerabang, ketebalan kerabang, persentase albumen, dan kuning telur., Silver brakel kriel are a breed of laying hens known for their excellent feed efficiency and egg-laying performance. The quality of silver brakel kriel eggs can be enhanced by providing them with a nutritious diet. Mealworm is an insect that distributed worldwide. Mealworms could be commercially used to supplement conventional protein, since they contain high crude protein and fat, including omega-3 and 6. Research was conducted to determine the external quality of eggs from silver brakel kriel fed with mealworm meal as a supplement feedstuff. This study used 72 eggs out of 30-34 weeks of silver brakel kriel chickens, divided into two treatments, six repetition, and three eggs per repetition. The external quality of eggs was tested two times, on the second and fourth week. The treatment ration consisted of P0 = 100% control ration and P1 = ration containing 4% mealworm meal. Data were analyzed using the Independent Sample T-Test method. Data analysis showed increased egg’s external quality, specifically in the yolk colour and shell weight pecentage. Adding 4% mealworm meal did not affect to egg index, egg weight, Haugh unit, shell weight, shell thickness, albumen and yolk percentage.

Judul: The Utilization of Mealworm as a Substitute Feed on Arabic Chicken (Gallus turcicus) with Different Varieties
Abstrak: Telur merupakan sumber protein hewani yang paling tinggi nilai biologisnya, dapat diartikan sumber protein yang mudah dicerna. Ayam arab merupakan ayam petelur unggul dengan produksi telur ayam tinggi yaitu 190-250 butir/tahun. Penelitian ini bertujuan menganalisis performa produksi ayam arab petelur dengan pemberian pakan mengandung ulat Hongkong (Tenebrio molitor L.) berdasarkan warna yang berbeda. Penelitian menggunakan 60 ekor ayam arab petelur gold, 60 ekor ayam arab petelur silver dengan pemberian pakan yang mengandung 4% ulat hongkong, 6 ulangan dan setiap ulangan terdapat 10 ekor ayam. Data dianalisis dengan menggunakan metode uji-t. Penelitian ini menghasilkan pemberian pakan dengan 4% ulat hongkong menunjukkan performa ayam arab silver yang lebih baik pada parameter konsumsi pakan, hen house production (HHP), dan massa telur terhadap ayam arab gold. Parameter konversi pakan dan bobot telur memiliki nilai yang relatif sama antara ayam arab gold dan silver., Eggs are source of animal protein that has the highest biological value, which is recognized as a digestible protein source. Arabic chicken are the superior laying hens with high egg production, that is 190-250 eggs/year. This study aims to analyze the production performance of brakel kriel by giving a feed that contain the mealworm (Tenebrio molitor L.) based on different colors. This study used 60 gold arabic chicken, 60 silver arabic chicken with feed that contained 4% mealworms, 6 repetitions and each repetition had 10 chickens. The data were analyzed using the t-test method. This study resulted in feeding with 4% mealworms showed the better silver arabic chicken performance on feed consumption parameters, hen house production (HHP), and egg mass against gold brakel kriel. The feed conversion parameters and egg mass had relatively the same values between gold and silver arabic chicken.

Judul: Utilization of terra/MODIS L1B data for analysis of horizontal wind profile in the troposphere
Abstrak: This study was concerned with horizontal wind derived from data collected with the Moderate-resolution Imaging Spectroradiometer (MODIS) on board the NASA’s Earth Observation System (EOS)-Terra satellite. The aim of this study is to develop a method for the estimation of horizontal wind movement in the troposphere based on Navier-Stokes equation. The method was applied to a calibrated and geolocated Terra/MODIS L1B 1 km data set. The data inputs to estimate surface temperature are retrieved from TIR (Thermal Infrared) bands 31 (10.780 μm to 11.280 μm) and 32 (11.770 μm to 12.270 μm). The obtained surface temperatures were later used to approximate geopotential height on a constant-pressure surface by using the modified Poisson equation. The main assumptions used are the hydrostatic equilibrium, ideal gas law, constant lapse rate and constant acceleration of gravity. Based on the distribution of geopotential height, the pressure gradient force is measured by the gradient of geopotential on an isobaric coordinate to present the horizontal wind profile. For certain topographic areas especially in the mountain ranges, there was a disadvantage of using pressure as a vertical coordinate which lead to inaccuracy. In spite of that, Terra/MODIS L1B data with 1 km spatial resolution can be used to estimate the horizontal wind movement in the troposphere.
