Abstract

APPLICATION OF FIELD HYDROACOUSTIC TECHNOLOGY FOR MARINE SCIENCE AND TECHNOLOGY Utilization hydroacoustic methods in recent years have become increasingly effective for estimating the abundance of marine fish, especially fish stocks, where is impossible to do with conventional methods approach. Widely hydroacoustic technology has been used to map and classify the content of the resource base of waters and benthic animals that are on the bottom, type of substrate and benthic biota. Target Strength (TS) is the most important factor in the detection and prediction of fish stocks by using hydroacoustic. The TS is a measure that can describe the ability of a target to reflect sound waves that come about it. In the propagation of sound waves, the amount of energy per second will be flowing through the unit certain area perpendicular to the direction of propagation. The amount of energy per second crossing a certain area of the unit refers to as the intensity of the wave. The system of detection and measurement of underwater involves three components, namely medium, targets, and equipment. Sonar equation is built based on the similarity or balance between the parts of the received signal, the desired (called signal) and the unwanted parts (referred noise or noise), depending on the specific sonar functions are applied.

Abstract

This community service begins with the understanding that the Geospatial Information Law No. 4 of 2011 mandates that geospatial information must be disseminated and known to the wider community. On the basis of this geospatial information law, community service activities are carried out for coastal communities and small islands regarding the understanding and skills of the Nongsa community, regarding the determination and mapping of fishing areas (MFA), and chlorophyll maps and depth maps, for approaches to Potential locations in the DPI are important so that coastal communities and small islands recognize the potential and spatial problems on Batam Island. This problem will certainly have an impact on the economy of coastal communities, with it being very difficult to determine the location of fishing, which is the main livelihood for the community. This activity includes the development of science and technology to the community, especially in the use of marine technology that can assist in determining fishing areas which will later help and create independence for coastal communities in Mubut Darat in determining fishing spots or areas in the area. The output of this community service program is increasing the understanding and skills of the community in the Nongsa sub-district, Batam regarding the determination and mapping of fishing areas (MFA), providing planks, making maps of fishing areas and developing teaching materials (textbooks) in Batam City. This activity ran smoothly and provided very new knowledge for the people on the island of Batam-Nongsa.
