Many ship dismantling activities were carried out traditionally by the community. One of those activities was around the Kamal Madura port. This business has long been conducted since the 1980s. During ship demolition activities, there were oil and grease, diesel fuel and debris left over from the material discharged to the surrounding environment. The purpose of this study was to characterize various physical and chemical parameters of seawater samples around ship dismantling activities. Sampling was carried out at 2 ship dismantling locations, i.e. location 1 showed the location of the activity age of approximately 10 years and the second location which has more than 20 years. The sampling method was carried out by grab samples of 3 sampling points for each ship dismantling location. The time of samplings were conducted for two times at different time. The determined physical parameters and chemical parameters were analysed based on methods from Quality Standard KepMenLH 51/2004 for third attachment (sea biota). Based on the results, turbidity at all point samplings showed value higher than the standard with ranged of 16 – 76 NTU. Some parameters i.e Total Suspended Solid (TSS), Biochemical Oxygen Demand (BOD), phosphate, nitrate, oil and grease, Lead (Pb), Cadmium (Cd), and Zinc (Zn) showed value higher than the standard. Other parameter i.e. Iron (Fe) showed high value than compared with KepMenLH (1988) and international standard for Fresh and Marine Water Quality. In conclusion, some parameters showed higher value than standard, indicated it needed some efforts to remediate those location so that the environmental quality can improve. [ABSTRACT FROM AUTHOR] |
