Abstract

Sonar is a technology that uses the propagation of sound waves to detect the position of an object. Usually, fishermen use sonar to detect fish locations. The problem is that the price of sonar is still expensive, so not all fishermen can afford to use it. One of the devices that can be developed is the HC-SR04 module. HC-SR04 has simple components, and the price is cheap. The use of HC SR04 is still very minimal, so it is necessary to analyze the accuracy of its distance readings on various objects and conditions. The research was conducted using experimental methods in August-September 2023 at the Fishing Exploitation Laboratory, Faculty of Fisheries and Marine Sciences, Brawijaya University. The distance data generated by HC-SR04 is used to measure ceramic, Styrofoam, and fish. Based on the research results, it is known that ceramic and styrofoam objects have a calculated t value = 0 while the one-tail Critical t = 1.65, which means the average distance produced by the tool is the same as the average distance by manual measurement. Meanwhile, in the t-test, the fish samples obtained a value of t stat = 23.24 and t Critical one-tail = 1.65. This shows that the tool will show distance measurement results that differ from manual measurements. Furthermore, the RMSE value of distance measurements on ceramic and Styrofoam objects obtained an average value of 0, which means the measurements are very accurate. Meanwhile, the average RMSE value for fish objects = 37.67, which means that the tool measurements are inaccurate.

Abstract

The fishing port, which acts as a public agency, provides services and facilitates fishing activities for fishermen. One indicator that the service provided is already optimal is the minimum number of vessels in the process of dismantling fish in the port. The study aims to find out the fishing landing system and the number of ships that landed during the period September–August 2022. The method used is directly through field observations and collecting secondary data to supplement the data obtained. The system applied to each port is different. The port of Pondokdadap applies the queue method as well as the system of nahkoda, where the ship's documents must be submitted and the fisherman's number taken before landing. Boats that want to sell fish to the TPI must be equipped with a catch letter. In the period September–August 2022, the highest number of ships was found in June 2022, with 603. For the smallest number in January 2022, there were 22 ships. Based on the results obtained, it is known that the period of April–September has the highest number, while there is a decrease in the number in October–March. There was an increase in the number of vessels that carried out fishing, which was affected by the fishing season, with the high season in the Eastern season.
