Judul: The Adding Cinnamaldehyde on Feed for Growth Performance of Carp (Cyprinus carpio).
Abstrak: Sinamaldehid merupakan polifenol hasil metabolit sekunder tanaman kayu manis yang berperan dalam metabolisme karbohidrat dan menghambat deposit lemak sehingga performa pertumbuhan dapat meningkat. Penelitian bertujuan menganalisis pengaruh penambahan sinamaldehid berbeda dosis pada pakan terhadap performa pertumbuhan ikan mas (Cyprinus carpio). Penelitian terdiri dari lima perlakuan dengan tiga kali ulangan pada setiap perlakuan. Dosis sinamaldehid yang digunakan pada penelitian ini yaitu 0 g kg-1, 0,5 g kg-1, 1 g kg-1, 1,5 g kg-1, dan 2 g kg-1. Ikan mas ukuran 8,82 ± 0,02 g dipelihara pada waring berukuran 100 x 100 x 200 cm3. Setiap waring diisi dua puluh ekor ikan mas (20 ekor/m2) dan diberi pakan perlakuan dua kali sehari secara at satiation selama 60 hari. Hasil penelitian menunjukkan bahwa pertumbuhan, efisiensi pakan, rasio efisiensi protein dan konversi pakan ikan mas yang diberi perlakuan sinamaldehid lebih baik dan berbeda nyata dibandingkan pakan tanpa penambahan sinamaldehid (P<0,05)., Cinnamaldehyde is a polyfenol from secondary metabolism of cinamon tree that functioned in carbohydrates metabolism and inhibit fat deposition that increase growth performance of carp (Cyprinus carpio). This research aim to analyze the impact of adding cinnamaldehyde with different dose on feed for growth performance of carp (Cyprinus carpio). This research contain five treatment with three replication on each treatment. The doses of cinnamaldehyde that used on this research is 0 g kg-1, 0,5 g kg-1, 1 g kg-1, 1,5 g kg-1, dan 2 g kg-1. Carp sized 8,82 ± 0,02 g were kept on dragnet sized 100 x 100 x 200 cm3. Each net filled with twenty carp (20 carp/m2) and get feeding two times a day in at satiation method for 60 days. The result of this research show’s that carp given by cinnamaldehyde treatment’s better and significantly different compared feed without cinnamaldehyde (P<0,05).

Judul: The Adding Cinnamaldehyde to Commercial Feed on Growth Performance of Vannamei Shrimp Litopenaeus vannamei
Abstrak: Sinamaldehid merupakan kandungan utama pada minyak atsiri kayu manis yang memiliki kemampuan dapat meningkatkan pemanfaatan sumber energi pakan sehingga kinerja pertumbuhan ikan lebih efisien. Penelitian ini bertujuan mendapatkan dosis efektif penambahan sinamaldehid pada pakan untuk meningkatkan kinerja pertumbuhan udang vaname (Litopenaeus vannamei). Penelitian terdiri dari lima perlakuan berbeda dengan empat kali ulangan pada setiap perlakuan. Dosis sinamaldehid yang digunakan pada penelitian ini yaitu 0 ml/kg, 0,5 ml/kg, 1 ml/kg, 1,5 ml/kg, dan 2 ml/kg. Udang vaname ukuran 2,06 ± 0,02 g dipelihara pada akuarium 60 x 40 x 40 cm3 dengan ketinggian air 30 cm. Setiap akuarium diisi 15 ekor udang (60 ekor/m2 ) dan diberi pakan perlakuan empat kali sehari secara restricted selama 60 hari. Hasil penelitian menunjukkan bahwa pertumbuhan, efisiensi pakan, rasio efisiensi protein dan konversi pakan udang vaname yang diberi perlakuan sinamaldehid lebih baik dan berbeda nyata dibandingkan SN 0 (P<0,05). Nilai kinerja pertumbuhan tertinggi didapatkan pada udang vaname yang diberi pakan dengan penambahan dosis sinamaldehid 1,5 ml/kg (P<0,05)., Cinnamaldehyde is the main ingredient in cinnamon essential oil which has the ability to increase the utilization of feed energy sources so that fish growth performance is more efficient. This study was intended to get the effective dose of cinnamaldehyde addition to feed to improve the growth performance of vaname shrimp (Litopenaeus vannamei). The study consisted of five different treatments with four replications in each treatment. The doses of cinnamaldehyde used in this study were 0 ml/kg, 0,5 ml/kg, 1 ml/kg, 1,5 ml/kg, and 2 ml/kg. Vaname shrimp size 2.06 ± 0.02 g were kept in 60 x 40 x 40 cm3 aquarium with a water level of 30 cm. Each aquarium was filled with 15 shrimps (60 shrimps/m2 ) and fed the treatments four times a day restricted for 60 days. The results showed that the growth, feed efficiency, protein efficiency ratio and feed conversion of vaname shrimp treated with cinnamaldehyde were better and significantly different from SN 0 (P < 0.05). The highest growth performance value was obtained in vaname shrimp fed with the addition of 1,5 ml/kg cinnamaldehyde dose (P < 0.05).

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.
