Judul: Pengaruh Suplementasi Lisin dan Seng dalam Ransum Murah yang Disusun dari Bahan Makanan Lokal terhadap Karkas Babi
Abstrak: Kualitas daging dipengaruhi oleh berbagai hal antara lain adalah faktor makanan. Makanan adalah salah satu kategori tunggal yang menelan biaya terbesar dari ongkos produksi. Penggantian dari salah satu atau beberapa bahan makanan konvensional biasa dilakukan sepan jang penampilan produksi yang diharapkan masih menguntungkan secara ekonomi. Bahan makanan ternak yang umumnya terdiri dari bahan nabati sering defisien akan salah satu atau lebih asam amino yang esensial sedangkan ketersediaan mineral sering kurang untuk memenuhi kebutuhan.

Judul: Pengaruh tepung gaplek yang disuplementasi metionin dan lisin sebagai subtitusi jagung dalam ransum terhadap kualitas karkas babi periode pengakhiran
Abstrak: Penelitian ini dilakukan di kandang Laboratorium Ilmu Produksi Ternak Babi, Fakultas Peternakan, Institut Per- tanian Bogor dan Rumah Potong Hewan Kotamadya Bogor, Jawa Barat. Waktu penelitian adalah selama sepuluh minggu (72 hari) yaitu dari tanggal 29 September sampai 15 1990. Desember Tujuan penelitian ini adalah untuk melihat pengaruh penggantian jagung dalam ransum dengan gaplek. Untuk meningkatkan mutu gaplek dilakukan penambahan lisin dan metionin. Metionin ditambahkan sebanyak 0.05 persen dari jumlah gaplek. Lisin ditambahkan sebanyak dua kali jumlah metionin. ransum Untuk mengetahui kualitas hasilnya dibandingkan dengan ransum substitusi basal yang biasa dipergunakan di Laboratorium IPT Babi Fakultas IPB dan campurannya dengan ransum substitusi. Peternakan Ternak percobaan yang dipergunakan adalah 24 ekor ternak babi periode tumbuh pengakhiran yang terdiri dari 12 ekor ternak babi jantan kastrasi dan 12 ekor betina dengan rataan bobot awal 51.75± 7.01 kg (koefisien variasi adalah 13.55 persen). Rancangan penelitian yang dipergunakan adalah Ran- cangan Acak Blok Lengkap dengan enam perlakuan ransum dua blok tiap perlakuan. Setiap blok terdiri atas ekor ternak dan blok disusun berdasarkan jenis dan dua kelamin. Untuk mengetahui hasil perlakuan dilakukan uji banding ortogonal. Ransum perlakuan yang dicobakan dalam penelitian ini adalah enam macam jenis ransum masing-masing sebagai berikut: A (ransum basal), B (40 persen jagung, 0 persen gaplek), C (0 persen jagung, 40 persen gaplek), D (campur- an B dan C atau sama dengan 20 persen jagung + 20 persen gaplek), E (campuran A dengan B) dan F (campuran A dengan C)...

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.
