Abstract

Handline tuna fishing constitutes one of the key economic activities in coastal areas, particularly for small-scale fishermen. Efficient working time plays a vital role in improving fishermen’s productivity and income. However, in practice, tuna fishing operations frequently encounter inefficiencies in both planning and the execution of daily tasks. Therefore, an analytical method is required to identify and evaluate each stage of the work process systematically. The Program Evaluation and Review Technique (PERT) provide a structured approach to mapping work activities, estimating the time required for each task, and identifying the critical path that determines the total project duration. This study aims to evaluate the efficiency of working time utilization among tuna fishermen using handline gear by applying the PERT approach. The research was conducted on 163 fishing vessels using the PERT (Project Evaluation and Review Technique) method, focusing on the analysis of actual time allocation for each activity. The results indicate that of the 24 analyzed activities, 17 (70.83%) fall within the critical path, while 7 (29.17%) have slack time. Critical activities such as loading supplies, traveling to the fishing ground, and retrieving the parachute anchor determine the project’s minimum duration. Meanwhile, activities with slack time, such as preparing the parachute anchor and mooring the vessel to the fish aggregating device (FAD), can be performed flexibly without affecting the overall project timeline. Effective time management is essential to ensure that each operational phase is completed on schedule, thereby improving the efficiency and productivity of fishing operations. Keywords:   critical path, handline, PERT, tuna.

Abstract

Maintaining the potential sustainability of fish resources in the sea, the government began “Code of Conduct for Responsible Fisheries (CCRF)” concept since it was adopted at the FAO Conference on October 31, 1995 to overcome irregularities in capture fisheries activities. The criteria for environmentally friendly fishing gear must have high selectivity, the gear does not damage the habitat, does not endanger the lives of fishermen, produces quality fish, the product does not endanger consumers, low by-catch, fishing gear provides minimal impact efforts on the diversity of biological resources, does not catch protected biota species that are threatened with extinction and is socially accepted by the community. The purpose of this study is to determine the environmental level friendliness of purse seines by means of observation, documentation, and interviews. The purse seine catches results in the study at KM. Berkah Sandrego 2 consists of Sardinella gibbosa by 25%, Amblygaster sirm by 27%, Selarodies leptolepis by 19%, Selar crumenophthalmus by 8%, Atule mate by 4%, Rastrelliger kanugarta by 6%, Euthynnus affinis by 9%, and other catches by 2%. The 88.32% catch total is the main catch (HTU), while 11.68% is bycatch (HTS) with total catch of fish that can be utilized at 100% and unutilized total catch at 0%. The assessment shows that this fishing gear is in the environmentally friendly category. The evaluation resulted in a score of 28 and a total score of 848, which proves that the purse seine is in the 28-36 category (very environmentally friendly).
