Abstract

Seaweed culture is one of the economical activities in the marine coastal of Bantaeng regency, South Sulawesi, Indonesia. The study aims to identify the seaweed production based on and oceanographic factors and the distance of culture location from river mouth. The study was conducted from January to April 2022 in marine coastal of Bantaeng regency. The site selection was based on distance of the seaweed culture location from river mouth. Station A was 1 km from river mouth, station B was 2 km from river mouth, and station was 3 km from river mouth. Seaweed production was measured during harvest. Temperature, salinity, pH, brightness, and current velocity was measured in each site study during culture activity. Seaweed production from Station A was 8.200-11.300 kg wet/ha, Station B was 8.900-11.900 kg wet/ha, and Station C was 9.100- 12.800 kg wet/ha. The oceanographic factors including temperature ranged 29.1-31.2 oC, salinity ranged 25.3-36.5, pH ranged 7.1-8.4, brightness ranged 1.5-5.6 m, current velocity ranged 2.1-184.cm/sec. The results of the study showed that oceanographic factors in this area was suitable for seaweed culture.
