Physical and chemical conditions of waters for seaweed cultivation in Morowali, Central Sulawesi, Indonesia

This study was aimed to examine the physical and chemical conditions of the seaweed growing areas in Morowali Regency. It was carried out in January–August 2019 in 13 sub-districts of Morowali Regency, however the sample was taken from 3 sub-districts, South Bungku District, Witaponda District, and Petasia District, because not all districts have seaweed cultivation locality. Data sampling was done in three observation stations, consisting of several research sub-stations. The result showed that only two of the fourteen criteria—carbon dioxide and nitrate—were found to be unfavorable for seaweed growth at three observation stations.
