Judul: Manipulation of cholesterol and omega-3polyunsaturated fatty acids composition of chicken egg through the used of prawn waste and “Lemuru” fish oil
Abstrak: Peningkatan sadar gizi dan kesehatan kalangan masyarakat menengah ke atas mendorong kecenderungan untuk menghendaki produk unggas yang rendah lemak dan kolesterol namun tinggi asam lemak omega3 khususnya EPA (Etkosapentaenoat) ) dan DFTA (Dokosaheksaenoat. Asam lemak omega-3 itu sangat penting bagi perkembangan kecerdasan anak di samping itu befungsi juga dalam ha1 mencegah penyakit kardiovaskuler (aterosklerosis dan jantung koroner), kanker, tumor dan berpengaruh pada kekebalan tubuh dan kadar lipida darah serta menurunkan kandungan kolesterol, trigliserida, LDL (low density lipoprotein)dan meningkatkan kandungan HDL (high density lipoprotein) (Hunter, 1987 dan Simopoulos, 1989).

Judul: Suplementasi kromium organik dan @-amilase serta lipase ke dalam ransum ayam petelur yang mengandung kepala udang dan minyak ikan lemuru
Abstrak: Tujuan penelitian ini adalah menguji efektivitas bio-chrome, a-amilase dan lipase dalam ransum ayam petelur serta menghasilkan telur yang rendah kolesterol dan kaya akan asam lemak omega-3. Dalam Penelitian ini menggunakan kepala udang yang dihidrolisis dengan 6% HCI dipanaskan dalam autoclave dengan tekanan 1 kg/m² pada suhu 120 °C selama 45 menit Pakan tersebut telah terbukti mampu mereduksi absorbsi lemak dan kolesterol. Selain itu ransum berkepala udang tersebut diperkaya dengan 0.2% Methionine hydroxy analogue (MHA), 0.25% lisin monoklorida serta 3% minyak ikan lemuru (Sardinella lemuru). Penggunaan MHA dan HCL-lisin ditujukan sebagai prekursor carnitin yang membawa asam lemak rantai panjng untuk dioksidasi dalam mitokodria.

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.
