Plastic pollution in Ambon Bay

Abstract

Ambon has problems with plastic pollution, both in the rivers and the bay. Due to faults in the waste system, 60 tons of waste is not collected in Kota Ambon. This waste ends up in illegal landfills, the waste is burned or thrown in the water. The plastic pollution in the bay contributes to the global problem of plastic soup. Research was conducted based on question; which recommendations can be given to collect the floating plastics in the rivers around Ambon Market by using the litter traps. To answer the main question, sub-questions are drafted covering the sources of pollution, possible locations, and the possibilities for a trap. The research is conducted using different methods that is interview to local experts, observation, literature research and talks to residents. Most of the plastic found are single-use plastics, like water and food packaging materials. The most feasible location for a litter trap is the end of Batu Merah River due to the abundance of plastic, the depth, and the nearby presence of Speed Sampah. The concept litter trap showed that this device could be effective at Batu Merah River. Further research is needed to create a more definitive solution for plastic pollution. Several aspects must be taken into account, such as the circumstances like the rainy season, sedimentation, current, and tide can impact the working of the litter trap and should be considered during the designing process.
