Judul: Mempelajari proses pembuatan kecap udang peci (Metapenaeus ensis) secara hidrolisa enzimatis
Abstrak: Skripsi ini disusun berdasarkan hasil penelitian yang dilakukan di Bangsal Percontohan Pengolahan Pertanian Fakultas Teknologi Pertanian (AP) Hasil Institut Pertanian Bogor, pada bulan November 1990 hingga bul an Desember 1990. Penelitian ini bertujuan untuk mengetahui pengaruh penambahan enzim bromelin dan papain terhadap kecap udang serta jenis dan konsentrasi enzim dapat menghasilkan kecap udang yang mempunyai bail. mutu yang mutu Perlakuan yang digunakan dalam penelitian dibagi dua yaitu sumber enzim (papain, bromelin ini dan campuran bromelin dan papain) serta lama hidrolisa (8, 10 dan 12 hari). Rancangan percobaan yang dilakukan dalam peneli- ini adalah rancangan acak lengkap, percobaan tian faktorial dengan tiga kali ulangan dan analisa dilaku- kan secara duplo. Parameter yang diujikan adalah kadar protein, pH, kekentalan, kepekatan warna, uji mikrobiologi kadar ...

Judul: Pengaruh penggunaan enzim papain selama proses hidrolosis kecap ikan
Abstrak: Kecap ikan adalah produk tradisional yang sudah dike- nal baik di Indonesia maupun diluar negeri. Produk ini mempunyai aroma dan citarasa yang khas. Pada pembuatan ke- cap ikan tradisional dilakukan secara fermentasi dengan pe- nambahan garam sebagai senyawa pengontrol mikroba. Selain dengan cara fermentasi kecap ikan dapat dibuat dengan cara hidrolisis enzimatis. Produk kecap ikan hidrolisis enzimatis ini adalah produk kecap ikan yang dalam pembuatannya ditambahkan enzim yang berfungsi untuk mempercepat hidrolisis protein ikannya sebagai salah satu cara mengatasi waktu fermentasi kecap ikan yang lama sampai 12 bulan). (6 Pada penelitian ini dilakukan pembuatan kecap ikan hi- drolisis enzimatis dengan penambahan enzim papain. Kon- sentrasi enzim papain yang digunakan adalah 4%, 6% dan 8%. Berdasarkan kandungan total-N-nya tertinggi pada konsentra- si 8%. Pengaruh penambahan enzim ini diamati selama hidro- lisis. Untuk konsentrasi tertinggi (8%) selama hidrolisis antara 3 sampai 10 hari mengalami peningkatan nilai total-N antara 1.12 1.63 g N/100ml, TVN antara 60.40 121.90 mg - - N/100 ml, volume hidrolisat antara 35.50 41.30% (/b), ...

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.
