Study of Physico-chemical Parameters of Water and Soil around Pancana Beach, Barru Regency for Eucheuma Cottonii Seaweed Cultivation

Abstract

This study aims to determine the possibility of cultivating Eucheuma cottonii-type seaweed based on the study of physico-chemical parameters of water and soil around Pancana Beach, Barru Regency, Indonesia. The research was carried out for 2 months, from July to August 2022, by conducting four sampling times for the study of cultivation aspects, including physico-chemical water and soil parameters. Determination of research locations based on differences in environmental characteristics at each research location. Station (ST) A is located on a small river around Butung-Pancana, Station (ST) B is located around residential areas, and Station (ST) C is located around the estuary of Pancana. The data collected consisted of water physico-chemical parameter data, namely water temperature, salinity, water pH, water dissolved oxygen, phosphorus (PO₄), and N-Total water. On the other hand, the soil parameters include the value of soil pH and soil texture. The data obtained were then collected, processed, and analyzed by descriptive analysis.

The results showed that the value of the water physico-chemical parameters in the research location, namely around Pancana Beach, Barru Regency, Indonesia, which consisted of water temperatures in the range of 28.1-28.9, dissolved oxygen 4.18-6.01 ppm, water pH in the range of 6.3-7, salinity 31.33-32.33 ppt and PO₄ and N-Total at the beginning and end of the study, were in the appropriate range, while the pH value of the soil is in the range of 7.82-8.01 and the soil texture is a sandy texture. Thus, it can be stated that the waters of Pancana Beach, Barru Regency are still suitable for the cultivation of Eucheuma cottoniii seaweed based on the physico-chemical parameters of water and soil.
