Temporal Distribution and Characteristic Analysis of Oil Spill in Balikpapan Bay

Abstract

Balikpapan Bay has an oil spill case that attracts many people because it is considered a serious environmental problem and is detrimental to the environment. One of the cases that occurred was the leak of an oil pipeline in Balikpapan Bay due to the wrong anchorage of a ship that occurred on March 31, 2018. Detection of oil spills for three months using Sentinel 1-A satellite data to determine the distribution and analysis of the same oil characteristics from the source of pipe leaks in the Gulf of Balikpapan. The multi-temporal distribution of oil spills in Balikpapan Bay in March, April, and May 2018 has a significant difference in the upstream and mouth of the bay due to a pipe leak on March 31, 2018. Characteristics of upstream oil spills represented by stations 4 and 5 have the anisotropy value is lower than at the mouth of the bay which is represented by stations 1 and 2. The characteristics of the oil spill in Balikpapan Bay have differences before and after the oil spill due to pipe leakage as indicated by the decrease in the anisotropy value.
