Abstract

Fishermen are highly susceptible to hearing impairment due to prolonged exposure to the high-intensity noise of boat engines. While numerous studies have investigated the noise intensity levels of boat engines, no research has been conducted on noise warning alarm systems for fishing boats. Therefore, this study aims to develop a sound noise alarm system based on Arduino Uno with a KY-037 sensor for fishing boats, which is expected to reduce the potential for hearing impairment among fishermen. This research employs a quantitative descriptive approach, with data collected through experimental methods and analyzed by comparing noise level data at various engine speeds. The results of the noise level measurements of boat engines at the Fish Landing Base (PPI) in Cikidang, Pangadaran Regency, indicate that the majority of fishermen are safe from hearing impairment due to engine noise, as most boats there are small, with a Gross Tonnage (GT) capacity of under 5 GT. The risk of hearing impairment emerges for boats with a capacity of 11 GT running at a maximum engine speed of 1600 rpm, producing noise levels up to 84 dB. Thus, it is recommended that crew members use earplugs.

Abstract

This study aimed to determine the effect of different bait types on the catch of larval shrimp (Macrobrachium lar) using a lift net and to determine the best bait type in the waters of Cijeruk Indah, Garut Regency, West Java. The method used in this study was an experimental method with nine replications. The independent variables in this study consisted of three types of bait: earthworms, fine rice husks, and pellets, while the dependent variable was the weight of the larval shrimp caught. The results showed that different bait types significantly affected the larval shrimp catch. Based on the total catch during the study, pellet bait yielded the highest yield, with a total weight of 2,316 grams. This was followed by fine rice husk bait with a total weight of 1,256 grams, and earthworm bait with the lowest yield, at 364 grams. Data analysis using ANOVA showed a significance value of 0.031 (p < 0.05), confirming a significant difference in catch responses between the three bait types. In conclusion, pellets are the most effective type of bait to use in the anco net fishing gear in catching larval shrimp at the research location.
