Judul: Pengolahan Feses Dan Darah Dengan Memanfaat Larva Hermetia Illucens Pada Taraf Penambahan Darah Yang Berbeda
Abstrak: Salah satu permasalahan dalam bidang peternakan adalah limbahnya. Limbah yang paling umum adalah feses. Di sisi lain, darah juga menjadi limbah yang bermasalah karena metode penanganannya yang masih terbatas. Terdapat metode pengolahan alternatif yang lebih murah seperti pemanfaatan satwa harapan dalam pengolahan. Hermetia illucens memiliki fase larva yang lebih panjang dari lalat lain pada umumnya serta memiliki kemampuan konsumsi yang tinggi.Penelitian ini bertujuan untuk memanfaatkan larva H. illuccens sebagai dekomposer limbah feses dan darah. Perlakuan berupa penambahan darah pada taraf yang berbeda, yaitu 7.5%, 15% dan 22.5% (P7.5, P15 dan P22.5). Hasil menunjukkan bahwa P7.5 memiliki nilai WRI paling tinggi.Hasil yang diperoleh dari perlakuan berbeda tidak menunjukkan perbedaan nyata, yang artinya pemanfaatan larva H. illucensmasih bisa diterapkan pada taraf penambahan darah yang lebih tinggi (>22.5%).Jumlah darah yang bisa dikonsumi oleh larva H. illucens setiap hari berkisar antara 18.19-45.64g (penambahan darah 7.5%-22.5%)Kompos setelah pemeliharaan tidak cukup baik untuk digunakan sebagai pupuk karena nilai C/N yang tinggi dan nilai KTK yang rendah; tetapi hasil pemeliharaan ini berpotensi sebagai media pemeliharaan cacing tanah karena kandungan C yang tinggi dan kadar ammonia yang rendah.

Judul: The utilization of blood from slaughterhouse waste as a high protein feed in increasing the biomass of worm lumbricus rubellus.
Abstrak: Pemotongan sapi di Rumah Potong Hewan (RPH) menghasilkan limbah organik cair berupa darah. Darah yang terbuang ke lingkungan tanpa proses pengolahan dapat mencemari lingkungan. Darah dapat dimanfaatkan sebagai pakan tinggi protein dalam budidaya Lumbricus rubellus. L.rubellus adalah cacing tanah subtropis yang memiliki kemampuan menguraikan limbah organik. Penelitian ini bertujuan menganalisa penggunaan taraf darah terbaik dalam meningkatkan biomassa dan produksi kokon L.rubellus. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) Taraf darah yang digunakan adalah 0%, 2.5%, 5% dan 7.5% dari jumlah pakan. Pakan yang digunakan terdiri dari feses sapi perah dan cacahan batang pisang. Data yang diperoleh dianalisa sidik ragam dan dilanjutkan dengan uji Duncant. Hasil penelitian menunjukkan bahwa penambahan taraf darah berbeda memberikan pengaruh nyata terhadap pertambahan biomassa dan jumlah kokon (P<0.05). Taraf darah 2.5% memberikan pertumbuhan biomassa dan jumlah kokon tertinggi sedangkan taraf darah 7.5% memberikan pengaruh terendah., Beef slaughterhouse produces liquid organic wastes such as blood. Blood which discharged into the environment without treatment process can pollute the environment. Blood can be used as high-protein feed in the Lumbricus rubellus culture. Lumbricus rubellus is subtopis earthworms that have the ability to decompose organic waste. This study aimed to analyze the best blood level that support biomass and L.rubellus cocoon production. This study used Completely Randomized Design and blood levels used were 0%, 2.5%, 5% and 7.5% of the feed total. The feed consisted of dairy cattle feces and shredded banana stem. The collected data were analyzed by ANOVA and Duncant’s Multiple Range Test at (p<0.05). The results showed that the addition of different blood level had a significant effect on increasing biomass and number of cocoons (p<0.05). Blood level of 2.5% gave the highest biomass growth and number of cocoons while the blood level of 7.5% gave the lowest effect.

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.
