serapan karbon berdasarkan klorofil-a di perairan danau toba kecamatan pangururan kabupaten samosir sumatera utara

CO2 emissions increase atmospheric CO2 concentrations, leading to acid rain, which ultimately enters water bodies and affects CO2 concentrations. To reduceCO2 emissions, it's important to understand the carbon sequestration in water bodies. Carbon sequestration describes the amount of carbondioxide that phytoplankton successfully binds. The purpose of this study was to determine the the carbon sequestration in Lake Toba, Pangururan District by concentration of chlorophyll-a. This research was conducted from July to September 2025 in the waters of Lake Toba, Pangururan District, Samosir Regency, North Sumatra Province. The method used is the survey method. Sampling was carried out at 3 stations, namely Tanjung Bunga Village, Pardomuan Village, and Parbaba Village. Sampling was carried out six times at once. Water quality parameters measured were chlorophyll-a, nitrate, total phosphorus (Total P), temperature, pH, transparency, dissolved oxygen (DO), and free carbondioxide (CO₂). The results showed that chlorophyll-a concentrations in the waters of Lake Toba ranged from 4.82 to 10.58 µg/L, classified as mesotrophic to eutrophic. The total carbon sequestration ranged from 328.57 to 727.26 kgC. The lowest carbon sequestration was at station 3 and the highest at station 1. The average carbon sequestration capacity in the waters of Lake Toba, Pangururan District, was 527 kgC.
