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: Evaluation of Feed Containing Mealworm on the Physical Quality of Golden Arabian Chicken Eggs (Gallus turcicus)
Abstrak: Penelitian ini bertujuan mengevaluasi pengaruh pemberian ulat hongkong dalam ransum terhadap kualitas fisik telur ayam arab golden. Penelitian ini menggunakan 80 ekor ayam arab golden fase layer dengan umur 26-29 minggu. Penelitian dilakukan di Lab.Lapangan Unit Sahara Terintegrasi sebagai tempat pemeliharaan ternak dan Lab. Nutrisi Unggas sebagai tempat pengujian kualitas fisik telur. Rancangan percobaan dan analisis data menggunakan uji independent sample t-test dengan menggunakan 2 perlakuan dan 8 ulangan dengan masing- masing ulangan terdiri atas 5 ekor ayam. Ransum perlakuan yang digunakan dalam penelitian ini adalah: P0 = ransum kontrol (tanpa penggunaan ulat hongkong) dan P1 = ransum mengandung ulat hongkong 4% ulat hongkong. Peubah yang diukur dalam penelitian ini adalah bobot telur, indeks telur, tebal kerabang, bobot kerabang, warna kerabang, warna kuning telur, % putih, kuning, dan kerabang telur, serta Haugh Unit. Hasil penelitian menunjukkan bahwa pemberian ulat hongkong sebanyak 4% nyata (P<0,05) meningkatkan warna kuning telur, namun tidak berpengaruh nyata terhadap peubah lainnya. Kesimpulan dari penelitian ini adalah ulat hongkong sebesar 4% dapat digunakan dalam pakan dan dapat meningkatkan kualitas telur dari segi warna kuning telur dari skor 8,51 menjadi skor 9,31., This research was aimed to evaluated the feed containing mealworm on the physical quality of golden Arabian chicken eggs (Gallus turcicus). This study used 80 golden Arabian layer chickens aged 26-29 weeks. The chickens were reared at Field Laboratory Unit Sahara Terintegrasi, while egg quality testing was analyzed at the Poultry Animal Nutrition Laboratory. Experimental design and data analysis used an independent sample t-test using 2 treatment and 8 replicate with each replicate consisting of 5 chickens. The treatment diet used in this study were: P0 = control diet (without the use of Mealworm) and P1 = diet containing 4% Mealworm. The variables measured in this study were egg weight, egg index, shell thickness, shell weight, shell color, yolk color, % egg white, % egg yolk, % eggshell, and haugh unit. The results showed that diet containing 4% Mealworm significantly (P<0,05) increased yolk color, but not significantly effect on other variable. The conclusion this study is that Mealworm of 4% can be used in feed and can improve egg quality in terms of egg yolk color from the score of 8.51 to score 9.31.

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.
