Abstract
Kendari Bay is receiving direct pressure from land clearing. This activity leads to sedimentation to the estuarine area. The sedimentation rate in Kendari Bay reaches up to 143,147 m3/year. The high amount of total suspended solids will impede light penetration. As a consequence, it will decrease the rate of photosynthesis, thus decreasing chlorophyll-a content. This research was aimed to understand the relationship between distribution total suspended solid (TSS) and chlorophyll-a concentration in Kendari Bay. Water sampling was done between January 21 and February 6, 2018. TSS and chlorophyll-a were measured in the laboratory. Data of TSS and chlorophyll-a from 2010 to 2018 were downloaded from Landsat 5 TM and Landsat 8 OLI. ENVI 5.1 and ArcGIS 10.1 software was used to visualize the distribution into a map. The relationship between two parameters was analyzed using linear regression. The TSS showed a linear increase from 2010 to 2018 with a concentration higher than 50 mg.l−1. The correlation between TSS and chlorophyll–a showed a negative correlation (0.6376) which indicated that the higher TSS, the lower the chlorophyll-a.
