Judul: Mempelajari sifat-sifat fungsional telur penyu (Chelonia mydas)
Abstrak: Tujuan dari penelitian ini adalah untuk mempelajari pengaruh pH, garam (NaCl), dan gula (sukrosa) terhadap daya koagulasi, daya buih dan sifat mengemulsi telur pe- nyu. Pengamatan terhadap sifat mengemulsi dilakukan untuk kuning telur, daya buih untuk putih telur, dan daya koagu- lasi untuk putih dan kuning telur. Hasil yang diperoleh menunjukkan bahwa putih telur penyu tidak dapat terkoagulasi sempurna seperti telur a- yam. Suhu maksimum yang dapat dicapai merupakan titik didih dari larutan putih telur tersebut. Kenaikan pH da- ri 7-ll atau kenaikan konsentrasi sukrosa akan menaikkan suhu awal koagulasi putih telur, dimana pada pH 11 tidak terlihat lagi timbulnya kekeruhan. Sebaliknya NaCl akan menstimulir proses koagulasi dengan menurunkan enurunkan suhu a- wal koagulasi. Dari pengamatan terhadap daya buih putih telur pe- nyu diperoleh bahwa waktu pengocokan yang optimum adalah selama lima menit, dimana adanya sukrosa dalam larutan putih telur akan meningkatkan waktu yang dibutuhkan untuk ...

Judul: Mempelajari pengaruh cara pengasinan telur penyu laut (Chelonia mydas) menggunakan adonan abu gosok dan garam dapur terhadap mutu telur asin selama penyimpanan
Abstrak: Penelitian ini oertujuan untu: melihat pengaruh perbe- dean koder crem drlem adonan, wohtu pengasinan dan wektu penyimpanan tern des mutu telur penyu asin. Ketika music bertelur produksi telur penyu serlimpah. Telur penyu memiliki dry tehen simpan dur minggu, membu- tuhcen suatu care pengaweten zupage depat diperkon ke- beberapa daersh. Pengasinan merupakan cara tradisionci yong sederhana prosesnya dan biayanys rendah. Pengasinan bertu- juan mencegah pertumbuhan mikrobe, sehingga dapat memperpan- jang waktu ponyimpanan. Cara pengawetan dengan pengasinan depot diterapkan peće telur penyu tetapi perlu diperhatikar. sifat-sifat khusus dari telur penyu. Pengasinan menggunakan adonan campuran abu gosok dan garam dapur dengan perbandingan bobot 4:1,6:1 Mar 8:1. Te- lur dibungkus adonan selama satu, dua, tiga, empet dan lime hori. Setelah pengerinen, telur dibersihiton duri adonan dan disirgen de kondisi ruang kemudian diuji mutunya pada entu sebelum disimpan dan waktu penyimpanan dua, empat, enam minggu. Ternyata perbedaan koder garam, wektu pengasinan dan waktu penyimpanan berpengaruh terhadap pH, kadar air, kadar ...

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.
