This study aims to determine the physical and chemical characteristics of coastal waters in Konawe Regency and to determine the levels of chlorophyll a, b, and total chlorophyll contained in the seagrasses Halodule uninervis and Enhalus acoroides found in the coastal waters of Konawe Regency, Southeast Sulawesi. The study was carried out from February to May 2024, with seagrass samples taken from three coastal areas: Batu Gong, Toli-toli, and Tapulaga, Konawe Regency. The study was conducted by measuring physical and chemical parameters using digital instruments and analyzing the levels of chlorophyll a and b in Halodule uninervis and Enhalus acoroides using the UV-Vis spectrophotometry method. The results showed that the water temperature at the three study sites was still within the standard range for marine life quality according to the Government Regulation of the Republic of Indonesia No. 22 of 2021, which is 28°C-30°C; TSS was only observed on the Toli-Toli coastal areas within standard limits at 20 mg/L; TDS values are 26 mg/L - 27 mg/L, well below the standard limit (1000 mg/L); water pH values of 7.2 - 7.5 fall within standard limits; water salinity ranges from 22% - 32%, below the standard limit (33% - 34%), and DO values range from 3.6 mg/L - 3.9 mg/L, which are considered low compared to the standard (>5 mg/L). The highest chlorophyll a content was found in the seagrass Enhalus acroides in the Toli-Toli area, at 25.32 mg/L, whereas the lowest chlorophyll a content was found in the seagrass Halodule uninervis at Batu Gong Beach, at 7.76 mg/L. The highest chlorophyll b contentwas found in the seagrass Halodule uninervis in the Tapulaga area, at 12.76 mg/L, while the lowest chlorophyll b content was found in Halodule uninervis at Batu Gong Beach, at 5.41 mg/L
