Optimal Shipyard Model Selection for Kutaraja Fishing Port, Aceh, Indonesia Using Fuzzy AHP and TOPSIS

The growing fishing fleet and need for sustainable fisheries management in Aceh necessitate reliable shipyard facilities. This study aimed to identify the optimal shipyard model for Kutaraja Fishing Port by integrating fuzzy analytical hierarchy process (fuzzy AHP) and technique for order preference by similarity to ideal solution (TOPSIS). We surveyed shipbuilders, engineers, fisheries officers, and academics using a structured questionnaire to evaluate technical, operational, and environmental criteria. In the analysis, fuzzy AHP assigned weights to each criterion using triangular fuzzy numbers, while TOPSIS ranked alternative shipyard models based on their closeness to the ideal solution. The slipway model emerged as the best choice with a score of 43.65%, followed by the graving dock (34.29%) and floating dock (22.06%). Thus, the slipway model is recommended as the most suitable solution to meet Aceh’s shipbuilding and maintenance needs, thereby supporting sustainable fisheries infrastructure development.
