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 pemberian beberapa jenis minyak goreng terhadap kadar kolesterol serum tikus
Abstrak: Penelitian ini bertujuan untuk mengetahui pengaruh pemberian minyak goreng dengan bahan baku minyak kedelai (Happy Salad Oil), minyak kelapa sawit (Bimoli), campuran minyak kedelai dan kelapa sawit (Sunrise), serta minyak bunga matahari (Sunflower Oil) terhadap kadar kolesterol total, kolesterol HDL, dan kolesterol LDL serum tikus. Penelitian dilakukan di Laboratorium Percobaan Hewan, Laboratorium Kimia Gizi, dan Laboratorium Biokimia Gizi, Jurusan Gizi Masyarakat dan Sumberdaya Keluarga, Fakultas Pertanian, serta di Laboratorium Biokimia, Fakultas Kedok- teran Hewan, Institut Pertanian Bogor. Penelitian dilaksanakan mulai bulan Februari hingga Juni, 1994. Tikus yang digunakan dalam penelitian ini adalah Rattus norwegicus, strain Wistar berumur 21 hari. Sebelum diberi perlakuan tikus diadaptasikan dengan keadaan laboratorium selama tujuh hari dengan diberi ransum standar. Ransum dibuat berdasarkan ransum standar AOAC (1984), yaitu ransum dengan 8 persen minyak kelapa (Vetco). Untuk perlakuan, ransum standar ditambah dengan minyak perlakuan sebesar 10 persen. Perlakuan berlangsung selama 28 hari. Analisa kolesterol dilakuan terhadap serum dengan metode CHOD-PAP (Pedoman Kerja Boehringer Mannheim Indonesia). Rancangan yang digunakan dalam penelitian ini adalah Rancangan Acak Kelompok, dengan lima ulangan (Sudjana, 1989). Tikus yang digunakan sebanyak 25 ekor, dikelompokkan menjadi lima kelompok berdasar bobot badan. Pengacakan dilakukan dalam setiap kelompok sehingga setiap ekor tikus mendapat perlakuan yang berbeda. Data dikelompokkan berdasar perlakuan, kemudian ditentukan nilai tengah dan standar deviasi dari masing-masing perlakuan. Selanjutnya data dibahas secara deskriptif.

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.
