This event is routinely held each year by FDC-IPB as a part of training for members. “The activities include data gathering of coral reefs, fishes and macrobenthos. The data gathered to identify water quality includes clarity, DO (dissolved oxygen), current speed, pH, salinity, and temperature. Besides that we also gather the data about social and economic conditions of surrounding community. This event has a purpose to preserve the coral reef ecosystem in Pramuka Island and its surroundings,” explained the head of the committee, Gokson Lindun Situmeang.
