Abstract

Negara Indonesia adalah negara maritim yang memiliki banyak pulau baik yang bernama maupun yang belum bernama. Salah satunya adalah pulau Raas Madura, dimana pulau ini memiliki sumber daya alam yang melimpah di sepanjang garis pantainya. Dibalik melimpahnya sumber daya alam tersebut masih terdapat masyarakat yang sebagian besar prasejahtera. Pemanfaatan yang berlebih (over exploitation) dan krisis ekonomi yang menyebabkan terjadinya persaingan untuk memperoleh sumber daya alam yang tersisa sehingga mengakibatkan terjadinya degradasi sumber daya alam. Sistem pengelolaan wilayah pesisir dan pulau-pulau kecil yang secara terpadu yang dapat mengatisipasi terjadinya degradasi sumber daya alam tersebut. Upaya ini harus didukung oleh pemerintah untuk memberikan kesejahteraan mayarakat di darah pesisir di pulau-pulau kecil. Kata kunci: degradasi, over-exploitation, pengelolaan terpadu, sumber daya alam COMMUNITY-BASED AND INTEGRATED MODELLING OF COASTAL AREAS AND SMALL ISLANDS MANAGEMENT (STUDY CASE ON RAAS ISLAND, SUMENEP REGENCY, MADURA)ABSTRACTIndonesia is a maritime country that has a large number of named and unnamed islands. One of the islands is Raas Island in Madura, in which this island poses overwhelming natural resources along its coastal line. Behind the overwhelming natural resources, there lives a disadvantaged community. The over exploitation and economy crisis create a competition in acquiring the remaining natural resources, which leads to natural resources degradation. The integrated management system in the coastal areas and small islands can anticipate the degradation of natural resources. This effort must be supported by the government to make the community in the coastal and small islands prosperous.Keywords: degradation, integrated management, natural resources, over exploitation

Abstract

Bengkoang Island is an unpopulated island in the northern region of the archipelago. The island is divided into 2 zones, Marine Protection Zone and Marine Tourism Utilization Zone, based on the zoning and management plan of the Karimunjawa National Park, Central Java. This research is aimed to observe the condition of the coral reef and coral community fish abundance in Bengkoang Island based on the zoning. There were 2 stations to represent each of the zones at depths of 5 and 10 meters. Line Intercept Transect (LIT) method was used along 100 meters to data the reef substrate and Visual Census method with Belt Transect was used to data the coral community fish. The result showed that the coral cover was the highest in Station 1 at 5 m which was located in the Marine Protection Zone with 80,31%, while the lowest was found in Station 2 at 10 m which was located in the Marine Tourism Utilization Zone with 18,81%. Meanwhile, the coral community fish abudance was the highest in Station 1 at 10 m with 15.600 individual/ha and lowest in Station 2 at 10 m with 4.280 individual/ha. Based on the result, it can be said that the condition of the coral reef ecosystem in Bengkoang Island varies with a high margin between the data stations. The result indicated that the coral reef ecosystem in the Marine Protection Zone was in a better condition than in the Marine Toursim Utilization Zone.DIFFERENCES OF CORAL REEF AND CORAL COMMUNITY FISH ABUNDANCE CONDITION BASED ON ZONING OF BENGKOANG ISLAND, KARIMUNJAWAABSTRACTBengkoang Island is an unpopulated island in the northern region of the archipelago.

Abstract

RESISTANCE COMPONENT ANALYSIS OF TRADITIONAL FISHING BOAT IN CILACAPMonohull fishing boats used to catch fish is modified into a catamaran boat. The purpose of this modification is to get more fish. Catamaran ship has a double hull, but with the double hull ships resulted in increasingly complex resistances. It is interesting to study in depth about the resistance components of Catamaran boat. Resistance Components not only consist of surge resistance, frictional resistance, and the form resistance but with the distance between demihull causing interference waves. There are many research results of Catamaran boat in that aspect, but the data and information obtained from the experiment is still inadequate. In addition, there is still lack of accuracy particularly in predicting interference resistance component in calm water (calm-water resistance) as a result of the distance between the demihull. This study aims to describe the resistance component at Catamaran boat by using slender body method. Keywords: catamaran, Cilacap, slender body method ABSTRAK Kapal ikan monohull yang biasa digunakan untuk mencari ikan dimodifikasi menjadi kapal catamaran. Tujuan modifikasi ini untuk mendapatkan muatan ikan yang lebih banyak. Kapal Catamaran mempunyai dua lambung, tetapi dengan adanya dua lambung mengakibatkan hambatan kapal semakin kompleks. Menarik untuk dikaji lebih lanjut tentang komponen hambatan kapal Catamaran. Komponen hambatan tidak hanya terdiri dari hambatan gelombang, hambatan gesek, dan hambatan bentuk namun dengan adanya jarak antar demihull sehingga menimbulkan interferensi gelombang. Sudah banyak dijumpai hasil riset kapal Catamaran pada aspek tersebut, tetapi data dan informasi yang diperoleh dari eksperimen masih kurang memadai. Disamping itu, masih ditemukan ketidak-akurasian khususnya dalam memprediksi interferensi komponen hambatan pada air tenang (calm-water resistance) akibat dari adanya jarak antar demihull tersebut. Penelitian ini bertujuan untuk memaparkan komponen hambatan pada kapal Catamaran dengan menggunakan slender body method.  Kata kunci: catamaran, Cilacap, slender body method
