Fishing in the waters of Palang Tuban are continuously carried out, one of which is the capture of jengki anchovies (Stolephorus indicus). The purse seine fishing gear is a productive and efficient tool for capturing jengki anchovies without requiring a fish aggregation device (FAD). Fishermen in Palang Waters often experience varying results, where some catch a large amount of fish, while others catch much less. Some fishermen operate their gear for shorter or longer periods, but this does not guarantee a higher catch. This study aims to determine the operational time of the purse seine gear on the catch of jengki anchovies, and also to examine the effect of different operational times on the catch. Data was collected through experiments with two different treatments, each repeated 16 times, totaling 32 data points. The main parameter analyzed in this study was the quantity or weight of the catch. The research method used was experimental fishing with t-test analysis. The results of the t-test with 16 repetitions at 04:00-10:00 WIB and 07:00-13:00 WIB showed average catches of 1.391 kg and 1.234 kg, respectively, with a significance (2-tailed) value of 0.340 > 0.05.

This study aims to analyze the effect of body angle variations on propulsion force and water resistance in swimmers through a biomechanical approach. This research is motivated by the importance of movement efficiency in swimming, where suboptimal body positions can increase drag coefficient, thus slowing down swimming speed. The method used is a quantitative experimental design, involving professional and semi-professional swimmers. Instruments used include a motion capture system to record body movements, force sensors to measure propulsion and water resistance, and biomechanical software to analyze force vectors and drag coefficient. The results show a significant difference in swimming performance based on body angle variations. At a 0° angle, the average propulsion force is 145.3 N with a drag coefficient of 0.92. At a 15° angle, the propulsion force increases to 162.7 N with the lowest drag coefficient of 0.78. Meanwhile, at a 30° angle, the propulsion force decreases to 150.1 N, and the drag coefficient increases to 0.88. These findings indicate that a 15° body angle is the most optimal position, as it minimizes water resistance and maximizes propulsion force, thus improving swimming movement efficiency. The implications of this study suggest that biomechanical approaches can be used to design more efficient swimming training programs. The findings are also beneficial for swimmers and coaches in developing more effective training strategies.
