Judul: Performa dan Respon Fisiologi Kambing Prasapih yang Diberi Milk Replacer Mengandung Tepung Maggot
Abstrak: Mortalitas kambing prasapih dipengaruhi oleh faktor seperti produksi susu induk, litter size, mothering ability, dan status nutrien. Pemberian milk replacer menjadi solusi untuk mencegah tingginya mortalitas kambing prasapih. Larva Black Soldier Fly (Maggot) memiliki protein kasar sebesar 36.6% dan lemak kasar sebesar 37.26% dapat digunakan sebagai sumber protein alternatif penyusun milk replacer. Penelitian ini bertujuan mengevaluasi pengaruh pemberian tepung maggot dalam milk replacer terhadap performa, dan respon fisiologis kambing prasapih. Penelitian ini menggunakan 12 ekor anak kambing umur dua minggu dengan rataan bobot badan 5.33 ± 0.93 kg. Perlakuan terdiri dari menyusu pada induk kambing (P1), diberi susu sapi segar (P2), dan diberi milk replacer menggandung tepung maggot (P3). Rancangan percobaan menggunakan rancangan acak lengkap. Peubah yang diamati adalah konsumsi nutrien, pertambahan bobot badan harian, bobot sapih, dan respon fisiologi. Hasil penelitian menunjukan bahwa P3 berpengaruh nyata meningkatkan konsumsi bahan kering jika dibanding perlakuan lainnya (P<0.05). Pertambahan bobot badan harian pada kambing prasapih yang diberi perlakuan milk replacer mengandung tepung maggot tidak berbeda nyata dibanding perlakuan kontrol (susu induk) dan susu sapi segar. Respon fisiologi kambing prasapih tidak berbeda antar perlakuan dan tidak menimbulkan efek negatif pada status fisiologi kambing prasapih.

Judul: Pemberian Milk Replacer Mengandung Tepung Maggot dan Jangkrik yang Dimaserasi terhadap Profil Hematologi dan Metabolit Kambing Pra-sapih
Abstrak: Penelitian ini dirancang untuk menganalisis pengaruh pemberian milk replacer mengandung tepung maggot dan jangkrik yang dimaserasi dengan pelarut methanol terhadap profil hematologi dan metabolit darah kambing prasapih. Ternak yang digunakan yaitu 16 Kambing Peranakan Ettawa, 8 jantan dan 8 betina dengan rataan bobot awal yaitu 4.45 ± 0.78 kg. Penelitian menggunakan Rancangan Acak Lengkap (RAL) dengan 4 perlakuan dan 4 ulangan. Perlakuan yang diberikan yaitu susu induk kambing (P1), milk replacer komersial (P2), milk replacer mengandung tepung maggot yang dimaserasi dengan pelarut methanol (P3), dan milk replacer mengandung tepung jangkrik yang dimaserasi dengan pelarut methanol (P4). Peubah yang diamati yaitu hemoglobin, hematokrit, butir darah merah, butir darah putih beserta diferensiasi leukosit, glukosa plasma, trigliserida, dan total protein. Analisis data menggunakan Analysis of Variance (ANOVA) dan diuji menggunakan Duncan Multiple Range Test. Hasil menunjukkan bahwa perlakuan tidak berpengaruh nyata terhadap hemoglobin, hematokrit, butir darah merah, dan butir darah putih serta masih berada dalam kisaran normalnya namun pada perlakuan P3 dan P4 dapat meningkatkan kadar eosinofil yang berbeda sangat signifikan dibandingkan perlakuan P1 dan P2 (P<0.01). Glukosa plasma, trigliserida, dan total protein pada perlakuan juga tidak berpengaruh nyata dan masih berada dalam kisaran normal. Simpulan, milk replacer mengandung tepung maggot dan jangkrik yang dimaserasi dengan pelarut methanol dapat digunakan sebagai pengganti susu induk kambing, meningkatkan kadar eosinofil, dan tidak mengganggu status kesehatan ternak.

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.
