Judul: Penggunaan Tepung Defatted Larva Black Soldier Fly Pengganti Meat Bone Meal terhadap Organ Pencernaan dan Status Escherichia coli Usus Puyuh
Abstrak: Penelitian ini bertujuan untuk mengevaluasi pengaruh substitusi meat bone meal (MBM) dengan tepung defatted larva Black Soldier Fly (TDLB) terhadap organ pencernaan dan status Escherichia coli usus puyuh. Penelitian ini menggunakan 285 ekor puyuh betina berumur 6 minggu dengan rata-rata bobot 153.3±3.7 g. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan 3 perlakuan dan 5 ulangan. Perlakuan yang diberikan yaitu P1= Ransum dengan 100% protein MBM tanpa TDLB, P2= Ransum dengan kandungan 50% TDLB menggantikan protein MBM, P3= Ransum dengan kandungan 100% TDLB menggantikan protein MBM. Hasil penelitian menunjukkan pengaruh yang tidak nyata (P>0.05) terhadap persentase dan panjang relatif organ pencernaan. Penggunaan ransum yang mengandung 50% dan 100% tepung defatted larva BSF sebagai pengganti protein MBM berpengaruh nyata (P<0.05) dalam menurunkan Escherichia coli digesta usus puyuh. Dapat disimpulkan bahwa tepung defatted larva BSF dapat digunakan sebagai alternatif pengganti MBM dalam ransum puyuh.

Judul: Penggunaan tepung Deffatted Larva Black Soldier Fly (Hermetia illucens) sebagai pengganti meat and bone meal terhadap kualitas fisik dan kolesterol Telur Puyuh
Abstrak: Penelitian ini bertujuan untuk mengkaji penggunaan tepung defatted larva dari lalat Black Soldier Fly (Hermetia illucens) sebagai pengganti Meat and Bone Meal (MBM) terhadap kualitas fisik dan kolesterol telur puyuh (Coturnix-coturnix japonica). Penelitian ini menggunakan rancangan acak lengkap dengan 3 perlakuan dan 5 ulangan. Ransum perlakuan yang diberikan yaitu P1: Ransum dengan kandungan 100% protein MBM tanpa tepung defatted BSF, P2: Ransum dengan kandungan 50% tepung defatted BSF menggantikan protein MBM, P3: Ransum dengan kandungan 100% tepung defatted BSF menggantikan protein MBM. Pengamatan kualitas fisik telur dilakukan selama empat minggu saat puyuh berumur 7,8,9, dan 10 minggu. Peubah yang diamati yaitu bobot telur, persentase bobot kuning telur, persentase bobot albumen, persentase bobot kerabang, tebal kerabang, haugh unit, dan warna kuning telur. Berdasarkan hasil yang diperoleh, pemberian 50% dan 100% tepung defatted BSF dalam ransum nyata meningkatkan (P<0.05) warna kuning telur dibandingkan kontrol yaitu 4.17 skala BASF 2001. Perubahan juga ditunjukkan pada pemberian 50% dan 100% tepung defatted BSF dalam ransum berpengaruh nyata (P<0.05) terhadap haugh unit, akan tetapi P1 memiliki nilai yang lebih tinggi daripada perlakuan P2 dan P3. Perlakuan tepung defatted BSF tidak memberikan perubahan terhadap persentase bobot kuning telur, persentase bobot albumen, persentase bobot kerabang, dan tebal kerabang telur puyuh. Penggunaan 100% tepung defatted BSF dalam ransum puyuh dapat menurunkan kadar kolesterol telur sebanyak 3.64 mg atau 35.30% dibandingkan ransum tanpa tepung defatted BSF.

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.
