Judul: Evaluation of Probiotic Administration of Black  Soldier Fly Larvae (BSF) on Internal Organs and Blood Hematology of Broiler  Chickens
Abstrak: Penelitian ini bertujuan untuk mengevaluasi pemberian suplementasi probiotik terhadap persentase bobot organ dalam, panjang relatif organ dalam, dan bobot organ imunitas broiler. Rancangan yang digunakan dalam penelitian adalah rancangan acak lengkap (RAL) dengan 5 perlakuan dan 5 ulangan, masing-masing ulangan berisi 10 ekor broiler. Perlakuan penelitian broiler terdiri dari P0 = pakan kontrol tanpa probiotik, P1 = pakan kontrol + 1 ml L-1 probiotik komersial, P2 = pakan kontrol + 1 ml L-1 probiotik larva BSF, P3 = pakan kontrol + 3 ml L-1 probiotik larva BSF, P4 = pakan kontrol + probiotik larva BSF 5 ml L-1. Peubah yang diamati adalah persentase organ dalam, persentase organ imunitas, persentase panjang relatif saluran pencernaan, dan hematologi darah. Hasil analisis evaluasi probiotik larva black soldier fly perlakuan (P4) dengan dosis 5 ml L-1 dapat memperbaiki organ empedu dan panjang relatif organ duodenum. Perlakuan (P1) dengan dosis 1 g L-1 dapat memperbaiki hematologi darah ditunjukkan pada peubah limfosit dan heterofil yang rendah.

Judul: Utilization of Liquid Probiotics from Fermentation  Black Soldier Fly Larvae (Hermetia illucens) on Performance Broiler
Abstrak: Penelitian ini bertujuan mengevaluasi penggunaan probiotik cair asal fermentasi larva black soldier fly (BSF) terhadap performa ayam broiler. Sebanyak 250 ekor broiler jantan strain Cobb CP 707 dibagi kedalam 5 perlakuan dan 5 ulangan menggunakan rancangan acak lengkap. Perlakuan terdiri dari P0 = Pakan broiler + air minum tanpa probiotik, P1 = Pakan broiler + air minum (1 ml L-1 probiotik komersil), P2 = Pakan broiler + air minum (1 ml L-1 probiotik asal fermentasi larva BSF), P3 = Pakan broiler + air minum (3 ml L-1 probiotik asal fermentasi larva BSF), dan P4 = Pakan broiler + air minum (5 ml L-1 probiotik asal fermentasi larva BSF). Hasil penelitian menunjukkan probiotik asal fermentasi larva BSF tidak berbeda nyata (P>0,05) terhadap performa broiler. Income over feed and chick cost (IOFCC) yang dihasilkan P4 lebih efisien dalam menghemat biaya pakan dan menghasilkan indeks performa tertinggi selama pemeliharaan dibandingkan perlakuan lainnya. Berdasarkan hasil tersebut diketahui bahwa penggunaan probiotik cair asal fermentasi larva BSF dalam air minum pada penelitian ini belum memberikan pengaruh yang signifikan terhadap performa ayam broiler namun masih dapat menguntungkan berdasarkan perhitungan IOFCC dan indeks performa dibandingkan perlakuan tanpa probiotik., This research aimed to evaluate the use of liquid probiotics from fermentation black soldier fly (BSF) larvae on performance broilers. A total of 250 male broilers strain Cobb CP 707 were divided into 5 treatments and 5 replications using a completely randomized design. The treatment in this study consisted of P0 = broiler feed + water without probiotics, P1= Broiler feed + water with 1 ml L-1 commercial probiotic, P2 = Broiler feed + water with 1 ml L-1 probiotics from fermentation BSF larvae, P3 = Broiler feed + water with 3 ml L-1 probiotics from fermentation BSF larvae, and P4 = Broiler feed + water with 5 ml L-1 probiotics from fermentation BSF larvae. The results showed that the use of probiotics from fermentation BSF larvae was not significantly different (P>0.05) on broiler performance. IOFCC produced using P4 is more efficient in saving feed cost and the highest performance index during maintenance compared to other treatments. Based on the results, it can be seen that the use of liquid probiotics from fermentation BSF larvae in drinking water in this study was not been significant effect on broiler performance however can be advantageous based on IOFCC calculations and performance index compared to without probiotics.

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.
