Abstract

Oil spill is a serious problem that could lead to economic and ecological losses, both in the shortand long term. On July 12, 2019, there occurred an oil leakage around YYA-1 oil platform of Pertamina HuluEnergi Offshore North West Java (PHE ONWJ), located off the northem coast of Karawang, Java Sea. Thisincident has caused the death of fishes and marine animals, damage to coral reefs, mangroves, and seagrass beds,and several health problems of Coastal communities. Therefore, it is necessary to map and monitor oil spills, sothat actions can be taken to prevent the spread of oil spills. This study aims to map the distribution of oil spillsin Karawang sea using multitemporal Sentinel-1 data from July to September 2019. The detection is carried outusing the adaptive thresholding algorithm combined with manual interpretation. The result shows that the oilspills spread around Karawang sea from YYA-1 platform to Sedari Village and there are oil spills spreading fromthe Central Plant F/S platform. The oil spills tend to shift westward from July to September 2019. This shifting issupposed to be influenced by current and wave factors that were dominant rnoving westward at that time. Basedon data processing, it was found that the oil spill area from July to September was respectively 24.79 km2, 20.05km2, and 27.12 km2.
