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: Thermal Characteristics and Dynamics of Tropical Cyclone over Western North Pacific Ocean: A Case Study of Typhoon Songda (Chedeng) 2011
Abstrak: The frequent occasion of Tropical Cyclone (TC) over Western North Pacific (WNP) Ocean lies from 10˚N to 26˚N and 121˚E to 170˚E. Sources of TC development come from warm ocean temperature where latent heat is released during condensation processes and subsequently concentrated in the boundary layer. Relative humidity at 850-700 hPa is responsible to produce the most intense storm. Meanwhile, weak vertical wind shear between 850-200 hPa is one of the dynamical factors that lead to the development of TC. Pressure level of 850-200 hPa is chosen to minimize the thermodynamic effect in the lower troposphere. Typhoon Songda (Chedeng in the Philippines) or TSC lasted from May 18th to 30th, 2011 and strengthened into powerful Super Typhoon stage between May 24th and 27th. Long curving track and the exhibition of all sequences of TC life cycle, TSC is then considered as an ideal case of TC. The objective of the study with case of TSC is to investigate the role of thermal characteristics and dynamics on TC intensity. The research is carried out by using Advanced Research of Weather Research and Forecasting model (WRF ARW model) version 3.3. Two domains are employed in the model. The first domain situate from 02˚N to 40˚N and 118˚E to 149˚E and cover spatial resolution () of 33.1 km. The second domain situate from 09˚N to 27˚N and 119˚E to 132˚E with of 11 km. Timestep of the model () is 120 seconds. The model is supported by the following physical parameterization, i.e., Yonsei University Scheme (YSU) in the boundary layer, Kain-Fritsch scheme (KF) in the cumulus, and WRF Single-Moment 3-class scheme in the microphysics. Initial meteorological condition prior to the formation of the cyclone is generated using WRF ARW standard-release model. Sensitivity of the model output is obtained from a selected single-parameter change scenarios, namely, 10 % to 20 % decrease and increase of wind shear initial data at 850-200 hPa, and by 10 % to 20 % decrease of relative humidity initial data at 850-700 hPa. The result showed that the negative correlations between wind shear and intensity are found in wind shear scenarios. Wind shears of 10 ms-1 which lead to strengthening of the wind intensity in the early period of Typhoon development are found in wind shear scenarios. The effect of wind shear changes on wind intensity is statistically significant in the 20 % wind shear scenarios. During mature stage, weak wind intensity occurred when wind shear increase as given in the WRF standard-release and the 20 % decreasing scenario. Different situation is found in the 20 % increasing scenario where wind shear tend to weak and lead to strong wind intensity at this stage. Meanwhile, the reduction of moisture supply at 850-700 hPa resulting from 20 % decreasing relative humidity play a major role in the weakening of wind intensity and reduces mechanical energy of the cycle process as much as 300 J kg-1.
