Abstract

There are more than 350 species of Chromis fish in the world. Its distribution covers tropical and subtropical water areas. Spesific geographical conditions determine fish development.  This study aims to analyze morphometric meristik, and the differences between chromis fish characters in Indonesia and Korea waters. The research methods were consisted of descriptive methods, Kruskal-Wallis, and Mann Whitney test.The result showed the total length of Abudefduf sexfasciatus found in Palabuhan ratu and Pramuka Island water territories are ranged from 9.9 to 10.2 cm and 7.7 to 13.0 cm.This fish has a dorsal fin, caudal fin which consists of 12-17 weak fingers, and ventral fin consists of 1 hard finger and 4-6 weak fingers. Abudefduf vaigiensis’ found in Palabuhan ratu, Buton Island, Sorong, and Korea water has each ranging total length from 6.0 to 10.6 cm, 10.9 -12.3 cm, 11 cm, and 5.0 to 8.6 cm.The differences are in the caudal and ventral fin. Morphometric characters of Abudefduf sexfasciatus found in Palabuhan ratu and Pramuka Island water territories relatively similar. Morphometric characters of Abudefduf vaigiensis found in Korean waters was not significantly different with Palabuhan ratu, Buton Island, and Sorong water territories. Compared with the other two locations, Abudefduf vaigiensis found the island of Buton water territory has closely related family with the Korean water’s

Abstract

Efisiensi penggunaan material insulasi polyurethane dapat diukur melalui perubahan kerapatan material dengan laju panas yang dihasilkan, atau perbandingan antara perubahan daya simpan terhadap biaya material insulasi yang dibutuhkan.  Pengaruh perubahan kerapatan tersebut diambil pada rentang nilai 30 – 50 kg/m3, yaitu berdasarkan data aplikasi di lapangan. Metode analisis dilakukan dengan menggunakan teori dasar perpindahan panas dengan menggunakan rancangan percobaan RAL faktorial pada laboratorium dan uji komputasi CFD dengan bantuan CFD LISA 76. Hasil analisis menununjukkan bahwa penggunaan material densitas insulasi yang efisien adalah penggunaan material insulasi dengan nilai pada kisaran 30 - 35 kg / m 3 dengan efisiensi  η = ± 0.7. Hasil penelitian ini diharapkan dapat memberikan informasi lebih akurat tentang penggunaan material insulasi polyurethane yang efisien dan efektif.

Abstract

Karimunjawa National Parks (TNKJ) is a marine conservation area which has 111.625 ha area with the majority ofresidents work as fishermen. Utilization of traditional fisheries zone intended for fishing activities. Therefore, fishing activities in TNKJ should be conducted in accordance with the principles of conservation. The aim of this study was to determine the winning fish fishery commodities in TNKJ. The selection of commodities was done by using comparative performance index (CPI). Analysis of potential fish resources is done with bioeconomic model. Optimizing the amount of fishing equipment was done by using linear goal programming (LGP). Feasibility of the business conducted by financial analysis. The results showed commodities TNKJ reef fisheries are pompano, and for pelagic fisheries are anchovies. Reef fish resource potential of 174 tons / year and pelagic fish of 22 069 tons / year. Appropriate fishing technologies for reef fisheries is the fishing rod elongation and traps, while for the pelagic fishery and gillnet fishing minnows on trolling lines. Financial analysis shows that all fishing gear is still viable to continue the effort. Key words: Selection commodities, fishing activities, Karimunjawa National Parks
