Judul: The Performance of Digestive Tracts and Internal Organs of Broilers by Administering Fractionated Palm Kernel Meal
Abstrak: VIRA MAGHFIRAH. Performa Bobot Organ Dalam dan Saluran Pencernaan Ayam Broiler dengan Pemberian Bungkil Inti Sawit Hasil Fraksinasi. Dibimbing oleh WIDYA HERMANA dan NAHROWI. Fraksinasi bungkil inti sawit (BIS) merupakan proses pemisahan cangkang dan inti sawit untuk mengurangi kandungan serat kasar. Tujuan dari penelitian ini adalah mengevaluasi pengaruh tingkat pemberian BIS fraksinasi dalam ransum broiler terhadap persentase karkas, organ dalam, saluran pencernaan dan panjang relatif usus ayam broiler. Sebanyak 336 ekor ayam broiler strain Ross dibagi ke dalam 3 perlakuan dan 4 ulangan. Setiap ulangan (kandang) berisi 28 ekor. Menggunakan Rancangan Acak Lengkap (RAL), dengan perlakuan P0 = Ransum kontrol (BIS 0%); P1 = Ransum dengan 5% BIS; P2 = Ransum dengan 10% BIS. Peubah yang diamati adalah bobot hidup, persentase bobot karkas, organ dalam dan saluran pencernaan, dan panjang relatif usus. Data dianalisis menggunakan ANOVA, jika hasil menunjukkan berbeda nyata (P<0,05) maka dilanjutkan dengan uji Duncan. Hasil penelitian menunjukkan signifikan (P<0,05) pada meningkatkan bobot hidup, persentase bobot karkas, ileum dan sekum tetapi menurunkan secara nyata persentase bobot gizzard, panjang relatif sekum dan kolon. Simpulan dari penelitian ini adalah penggunaan BIS fraksinasi hingga taraf 10% dinilai efektif terhadap broiler jantan strain Ross umur 35 hari.

Judul: Effect of Giving Palm Kernel Meal Fractionated Results on Broiler Chicken Performance
Abstrak: Penelitian ini bertujuan untuk mengevaluasi pengaruh pemberian bungkil inti sawit (BIS) sebagai campuran dalam ransum terhadap performa ayam broiler. Penelitian ini menggunakan 420 ekor day old chick (DOC) broiler strain Ross yang dibagi dalam 3 perlakuan dan 5 ulangan, setiap ulangan menggunakan 28 Ekor. Rancangan percobaan yang digunakan adalah Rancangan Acak Lengkap (RAL) dengan perlakuan P0 = pakan kontrol, P1 = ransum mengandung BIS hasil fraksinasi 5%, P2 = ransum mengandung BIS hasil fraksinasi 10%. Peubah yang diamati adalah konsumsi pakan, bobot badan, pertambahan bobot badan, konversi pakan (FCR), dan mortalitas. Data dianalisis menggunakan Analysis of Variance (ANOVA) dengan program SPSS versi 20. Hasil yang signifikan (P<0,05) diuji lanjut dengan uji Duncan. Hasil penelitian menunjukkan bahwa penambahan BIS fraksinasi 5% dan 10% pada ayam broiler periode finisher tidak berpengaruh nyata (P>0,05) terhadap konsumsi pakan, namun berpengaruh nyata (P<0,05) terhadap bobot badan, pertambahan bobot badan, dan konversi pakan. Simpulan hasil penelitian ini adalah BIS hasil fraksinasi dapat digunakan sebanyak 5% dalam ransum ayam broiler periode finisher.

Judul: Characteristic of Overshooting Top (OT) Based on  Himawari  8  Satellite  as  a  Convective  Cloud  Feature  that  Generates  Extreme Weather in the Java Island Region
Abstrak: Overshooting Top (OT) is a feature at the top of a convective cloud that is associated with extreme weather. Research on OT in tropical Indonesia is still very limited. The existence of geostationary satellites with wide area coverage and fast frequency observations is useful for observing the fast dynamics of the OT life cycle. Therefore, this study intends to analyze the relationship between OT and extreme weather, updraft and thermodynamic conditions of OT when extreme weather occurs, the best objective method for detecting OT in the day time and night time, and the spatiotemporal distribution of OT in the tropical region of Java Island during the 2018-2021 period. Based on visual analysis using visible channel and Himawari 8 sandwich products, 87% of extreme weather events in Java were accompanied by the appearance of OT. It indicates that the presence of the OT pattern is a convection cloud pattern or feature that is closely related to extreme weather events for the Java Island region. The existence of a time lag between the appearance of OT and extreme weather events on Java Island indicates that the OT of convection cloud can be used as a precursor or nowcasting for the appearance of extreme weather. Most of the convective cloud OT features during extreme weather events on Java Island have altitude that were only able to exceed the altitude of the equilibrium level and few were able to exceed the tropopause level of 9 km – 16 km. The difference in atmospheric conditions during extreme weather events on Java Island, which is in the tropics and subtropics, is a strong and unstable convective energy condition characterized by a larger CAPE, as well as unstable KI, LI, SI and TTI values. It is offset by kinematic factors in the form of a weak vertical wind shear (bulk wind shear 0-6 km) and a higher freezing point height. The difference between extreme weather events in the Java Island region and other tropical regions compared to subtropical regions is the strong updraft speed of convection clouds. The IRW Texture COMB algorithm based on the IRW-Texture Gradient modification and the COMB algorithm shows a significant increase in quality for detecting OT and non-OT pixels in Java. Rainy days with rainfall > 50 mm/day are very common in areas with an altitude of > 500 m. On the other hand, the level of convection activity which is indicated by the presence of OT and lightning is significantly reduced in this area. OT of convective clouds appear more frequently during the DJF season and less frequently during the JJA season. OT often appears during the day time and rarely at night time. Most OTs appear in the central part, away from the south and north coasts of Java Island during the day, while OTs that appear near the south and north coasts of Java Island can appear in the morning or afternoon.
