Judul: Pengaruh minuman kunyit bubuk terhadap kadar kolesterol serum tikus
Abstrak: Penelitian ini bertujuan untuk mempelajari pembuatan minuman kunyit bubuk, daya terima, dan pengaruh minuman kunyit bubuk terhadap kadar kolesterol serum tikus. Penelitian ini dilakukan di Laboratorium Percobaan Hewan, Kimia Gizi, dan Biokimia Gizi Jurusan Gizi masyarakat dan Sumberdaya Keluarga, Laboratorium AP4 Fateta, Biokimia FMIPA IPB, serta di Cianjur dalam pembuatan Formula, dari bulan April hingga Oktober 1996. Bahan yang digunakan dalam penelitian ini adalah kunyit, gula pasir untuk pembuatan minuman; kasein, mineral, vitamin, minyak mazola, selulosa, dan pati jagung untuk ransum tikus, serta zat-zat kimia untuk analisis. Alat-alat yang digunakan adalah alat pemeliharaan tikus, alat bedah tikus, alat untuk pembuatan minuman dan alat analisis kimia dan biokimia. Penelitian ini dilakukan dalam 2 tahap, yaitu penelitian pendahuluan dan penelitian lanjutan. Penelitian pendahuluan bertujuan untuk menentukan komposisi campuran kunyit dengan gula yang dapat diterima oleh panelis dengan taraf penambahan 25%, 35%, 45%, dan 55%. Sedangkan penelitian lanjutan bertujuan untuk melihat pengaruh minuman kunyit terhadap kadar kolesterol total, HDL, dan LDL serum darah tikus. Rancangan percobaan yang digunakan adalah Rancangan Acak Kelompok (RAK) dengan enam ulangan dan empat perlakuan. Pengaruh jenis minuman kunyit terhadap kadar kolesterol total, HDL, dan LDL serum tikus dianalisis dengan uji sidik ragam (ANOVA) rancangan acak kelompok dan uji lanjut beda nyata terkecil (BMT) dengan Duncan.

Judul: Pengaruh "Cookies" berserat bekatul dan kulit kacang tanah (Arachis hypogaea) terhadap kadar kolesterol total serum tikus
Abstrak: Penelitian ini bertujuan untuk mempelajari pengaruh kandungan serat makanan (dietary fiber) bekatul, tepung kulit kacang tanah dan campuran bekatul-tepung kulit kacang tanah pada "cookies" terhadap kadar kolesterol total serum tikus. Penelitian ini dilakukan di Laboratorium Kimia Pangan, Percobaan Makanan, Biokimia Gizi dan Laboratorium Percobaan Hewan Jurusan Gizi Masyarakat dan Sumberdaya Keluarga serta Pilot Plant Food Technology Development Centre IPB, dari bulan September 1993 sampai Februari 1994. Bahan yang digunakan dalam penelitian ini adalah bekatul padi, kulit kacang tanah, bahan-bahan "cookies", zat kimia untuk analisis, kasein, campuran vitamin, campuran mineral, pati jagung, minyak kelapa sawit, dan selulosa untuk ransum tikus. Alat-alat yang digunakan adalah alat untuk analisis kimia, alat untuk membuat "cookies", alat untuk uji organoleptik dan alat untuk percobaan hewan. Penelitian ini dilakukan dalam dua tahap, yaitu penelitian pendahuluan dan penelitian lanjutan. Penelitian pendahuluan bertujuan untuk mendapatkan tiga jenis "cookies" yaitu "cookies" bekatul, "cookies" kulit kacang tanah dan "cookies" campuran bekatul-kulit kacang tanah yang masih diterima oleh panelis dengan tingkat substitusi terbesar. Sedangkan penelitian lanjutan bertujuan untuk melihat pengaruh "cookies" berserat makanan bekatul dan kulit kacang tanah terhadap kadar kolesterol total serum dan berat badan tikus. Rancangan percobaan yang digunakan adalah Rancangan Acak Kelompok (RAK) dengan enam ulangan dan empat perlakuan. Data kolesterol total serum dan jumlah kumulatif ransum tikus dianalisis dengan uji sidik ragam (ANOVA) rancangan acak kelompok dan uji lanjut Beda Nyata Terkecil (BNT)

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.
