<![CDATA[Time efficiency in longline operations is a crucial factor in improving productivity, reducing operational costs, and maintaining the catch quality in tuna fisheries in the Indian Ocean. However, time management at each stage of the fishing operation has not been systematically measured, potentially leading to inefficiencies. This study aims to identify the stages of longline operations on the KM Permata 99 and analyze the time distribution of each activity using the Critical Path Method (CPM). The study was conducted from January–April 2024 in the Indian Ocean waters with a fishing base at Benoa Harbor, Bali. Longline operations consist of 28 activities divided into two main stages: the preparation stage (7 activities) with a total time of 80 minutes and the operation stage (21 activities) with a total time of 1,400 minutes. Based on the Critical Path Method (CPM) analysis, the total time of one operating cycle is 1,480 minutes or equivalent to 24.6 hours per daily trip. All activities are on the critical path with a total float (TF) value of zero, so that delays in one activity will directly impact the entire process. Increasing the number of crew members from an average of 18 to 25 was found to improve operational efficiency. These findings highlight the importance for Critical Path Method (CPM) based operational time standardization and optimization of the number and division of labor of crew members as part of fishing vessel operational management. This policy has the potential to increase business efficiency, reduce costs, and support sustainable fishing practices.]]>
