Abstract

Cakalang City is a nickname for the city of Bitung which is one of the Minapolitan areas and industrialization of capture fisheries in Indonesia. The purpose of this study is to assess the sustainability status of the Cakalang fisheries in Bitung and develop a strategy for managing the Cakalang fisheries in Bitung to be sustainable. Analysis of existing conditions and indexes for each dimension of sustainable management of skipjack resources, including ecological, economic, social, institutional and technological dimensions is carried out using the Multidimensional Scaling (MDS) approach with ordination techniques modified from the Rapfish program. The sustainability of cakalang fisheries in Bitung at 65.82 percent is in the fairly sustainable category (ecological dimension 46.46 percent, economic dimension 80.01 percent, technology dimension 65.83 percent, and institutional dimensions 58.57 percent), sustainability analysis shows Multidimensional sustainability index values indicate the sustainability status of the skipjack fisheries in Bitung is in a fairly sustainable category. Keywords: Bitung, skipjack, sustainability.

Abstract

Indonesian shipyards are generally dominated by shipyards classified as traditional shipyards. Marine and Fisheries Bitung of Polytechnic dockyard or also known as workshop fishing vessel training is one of the shipyards belonging to the Technical Execution Unit of the Ministry of Maritime Affairs and Fisheries. Currently, the shipyard is only used for repairing fishing vessels with a tonnage of less than 30 GT around the town of Bitung. The shipyard uses a slipway type construction or a pull dock that uses an electric winch. The large number of ship repair requests at Bitung Marine and Fisheries Polytechnic shipyard is the reason for the need to increase the capacity of the shipyard. A technology level assessment should be carried out in order to see to what extent the level of technology which includes components of humanware, technoware, infoware and orgaware meets the needs of ship repair at the shipyard. This research was carried out from June to August 2021 using the case study method and analyzed by calculating the TCC value (technological contribution coefficient) of the technological components of technoware, humanware, infoware and orgaware. The highest contribution value is the infoware component, while the technoware component has the lowest contribution. The marine fisheries Bitung Polytechnic shipyard shows that the value of technological contributions lies in the semi-modern classification. Keywords : technological level, technometric model, shipyard.

Abstract

The aim of this research was to determine the species composition (Kj) and the weight composition (Kb) of the catch using a bottom gillnet whom operated by fishermen the village of Kulu. The research was conducted from October to December 2020. The research method was experimental fishing using gillnets with a 3 inch mesh size. The fishing operation took place over 15 trips and the fishing area was around the waters of the village of Kulu. The results showed that the catch was 117 fish including 15 kinds of fish and one type crustacean. The composition based on the dominant fish species is Naso hexacanthus (29.06%), whereas the composition based on the dominant weight is Portunus pelagicus (33.6%). Keywords : bottom gillnet, composition, kulu village
