ANALYSIS OF WATER QUALITY PARAMETERS FOR SEAWEED (EUCHEUMA COTTONII) FARMING SITE SUITABILITY IN MANDAR BAY, WEST SULAWESI, INDONESIA

Abstract

This study aims to analyze the water quality parameters for seaweed (Eucheuma cottonii) farming. The study was conducted in water areas of Mandar Bay for 3 months. Water quality samples were analyzed in the water quality laboratory of Politeknik Pertanian Negeri Pangkajene Kepulauan, South Sulawesi, Indonesia. The method used was explorative research by using survey method and direct measurement field. Determination of stations used GPS. The data obtained were analyzed according to environmental parameters to determine the site suitability with Geographic Information System approach. Six water quality parameters which did not meet the requirements for seaweed farming business, i.e. current velocity, dissolved oxygen, BOD, COD, Nitrate and phosphate were found. The total water areas of Polewali Mandar Subdistrict were 1.252.66 ha, the site with highly suitable rate was 65.39 ha and the site with marginally suitable rate was 1.187.27 ha. Based on the village area, Polewali village had highly suitable site of 13.16 ha and marginally suitable site of 231.89 ha, Wattang village had no highly suitable site of 0 ha and marginally suitable site of 126.22 ha, Lantora village had highly suitable site of 11.30 ha and marginally suitable site of 142.12 ha, Takatidung village had highly suitable site of 39.85 ha and marginally suitable site of 142.23 ha and Manding sub-district had highly suitable site of 1.08 ha and marginally suitable site of 34481 ha.
