Water quality parameters collected were temperature, acidity (pH), dissolved oxygen (DO), salinity, transparency, turbidity, phosphate, nitrate and heavy metals mercury (Hg), Lead (Pb), Cadmium (Cd), Copper (Cu), Zinc (Zn), Nickel (Ni), As, and Chromium (Cr), and we compare the data with seawater quality standards stated by Ministry of Environment of Indonesia. We determined the status of water quality using the Storet method.
