Full text linkThe background of choosing this topics is to realize that unfavorable condition is occur in the national sea transports in which is a very weak competitiveness in having a cargoes share. Archipelagic state of Indonesia comprises 17,506 islands, has 5.8 million kilometers square of waters, and a large amount of market cargoes, however national armada just only can contribute a small number of national incomes, that marked by reaching only five percent share of the total export-import cargoes and only fifty percent share of the total domestics cargoes, in which the rest of them are occupied by foreign armada. Those are caused of the maritime sector income loss that in amount of U5D 18,4 millions yearly that consist of USD 12,4 millions in cargoes share and USD 6 millions in transhipment oportunities. The purpose of this study is to obtain the capability of Indonesian sea transport within globalization era by formulating a design the empowerment strategy to support decision making policy in sea transportation solving problem. The dilta are collected from interviewing and filling the polling by eighteen competence officers of the maritime stakeholders that come from three maritime institutions such as the regulator, the actors, and the users. SWOT analysis, computerized influence / dependence (I/D) matrix, and importance and performance analysis (IPA) methods are used for analyzed data. The results of this study is showed that the influence on and the dependency of the five key factors in technoware, the six key factors in humanware, the four key factors in infoware, and the five key factors in orgaware are founded to high, and should be developed.

Analisis Tingkat Keramahan Lingkungan Alat Tangkap Tramel Net di Teluk Palabuhanratu
Full text linkKrisis perikanan telah muncul di dunia, terutama untuk sumberdaya perikanan pantai, menurunnya stok ikan merupakan tantangan bagi pengguna sumberdaya dan pengelola perikanan. Masalahnya adalah semakin tingginya permintaan akan produk perikanan sebagai sumber protein hewani dan intensitas penangkapan ikan yang tinggi, penting untuk mengetahui tentang tingkat keramahan lingkungan alat tangkap trammel net yang beroperasi di Teluk Palabuhanratu. Tujuan penelitian ini akan menjelaskan tentang komposisi tangkapan, selektivitas alat tangkap dan tingkat keramahan terhadap lingkungan. Pengumpulan data dilakukan dengan cara experimental fishing. Analisis selektivitas hasil tangkapan dijelaskan melalui indeks keanekaragaman Shannon dan indeks dominansi Simpson. Analisis skoring digunakan untuk mengetahui tingkat keramahan alat tangkap terhadap lingkungan. Komposisi hasil tangkapan sasaran utama (32%) dan hasil tangkapan sampingan (68%). Indeks keanekaragaman jenis hasil tangkapan berkisar anatara 1,87-2,54 (indek keragaman tinggi; selektivitas alat tangkap rendah) dan indeks dominansi berkisar antar 0,09-0,20 (tidak terjadi dominasi spesies hasil tangkapan). Nilai total skoring berdasarkan kategori tingkat keramahan lingkungan adalah 25 termasuk dalam kategori alat tangkap kurang ramah terhadap lingkungan. Hasil tangkapan didominasi ikan berukuran kecil, jika kegiatan penangkapan berlangsung dalam jangka waktu yang lama tanpa ada mekanisme pengelolaan seperti sistem buka-tutup suatu wilayah pengelolaan atau pengaturan alat tangkap maka dapat dikhawatirkan akan berdampak terhadap kelestarian sumberdaya ikan

MODEL PENGEMBANGAN PERIKANAN DI PERAIRAN SELATAN JAWA
No full textDevelopment of fishery activity shall be conducted base on the characteristic of potency owned by a territotial water region. South Java water region has a characteristic condition of fisheries resources which need a specific management. Based on a fishery resources potency, South Java water region has a very big potency, but fishery activity just develop in a certain places only, namely Palabuhan Ratu, Cilacap and Prigi. The research has aim to build a model of fisheries development which is adopted by a regional characteristic. Method of the system approach used to analyse the problem and develop the model. System engineering compiled in a model with three submodels are 1) fishery effort (submodel USAHA), 2) requirement of PP/PPI, functionality and accessability (submodel PELABUHAN) and 3) policy and institution (submodel LEMBAGA). Firstly model determined commodity’s priority, strategy of model implementation using interpretative structural modellig (ISM) technique. The study resulted two models are 1) tuna fisheries development model and 2) coastal fisheries development model. At tuna fisheies development model, its expressed that tuna fishery business represent a high risk business, the government policy which do not support the business like increasing the fuel price giving big impact for continuing the business. Fishing port which capable to support tuna fishery’s business are PPS Cilacap and PPN Pelabuhan Ratu. Developments are require to be done by the intregrated institution which can accommodate the stakeholder needs. At the model of fisheries coastal development, the commodity’s priority are bonito, skipjack, white pomfret, hair tail, lobster, shrimp and anchovy. Fishery business covering gillnet multifilament, gillnet monofilament, purse seiner, trolling,’payang’, trammel net and ‘pancing rawai’. The effort can be done in middle scale or small scale. Existing PP/PPI mostly can be able to support fisheries acivity in each region. Role of KUD, HNSI and group of fisherman require to be improved for fisherman empowerment. Strategy of implementation model require to pay attention to the system which is a key element for succeeded the system

Full text linkThis paper will explain the result of cetacean reconaissance survey including investigation of abundance and diversity of cetacean related to the designing of a co management Marine Protected Area (MPA) in Berau, East Kalimantan. Berau islands consist of 31 very small islands that have high marine biodiversity including mangrove, coral reefs, sea grass. It has been found by this survey that Berau waters is a corridor for cetacean migration route, beside as home for green turtles and manta ray aggregation sites in Indonesia. This reconaisance survey in the frame oj Rapid Ecological Assessment using visual and acoustic method, indicated that cetacean existence is closely related to the coral reef ecosystem and small islands. Berau islands is an integral part of \u27Coral Triangle\u27 within marine mega biodiversity area, and it is inhabited by at least 10 species ofcetacean.Conservation of marine cetacean in the frame work of MPA will ensuresustainable marine resource use, including tourism and fisheries, for the benefit of local communities. The strategies pursuant to this goal will be arrived upon through the linkage of partnerships that have been created, and the objective will be achieved by establishing a large, co-managed Marine Protected Area that will include extractive use zones, non-extractive use zones and fully protected (no-take) zones. Partnership amongstgauernment and NGOs has already been innitiated in Berau. Currently the MPA boundary covers an area of 1.2 million Hectars of Berau waters, including corridor of cetacean migration, that has been formalized through District Decree No.31/2005.Keywords: Marine Protected Area, Rapid Ecological Assessment, Marine Cetacean
