Abstract

The research was one part of oil spill contingency plan (OSCP) developed for Delta Mahakam area, where oil & gas exploration and exploitation linked with rich biodiversity supporting coastal community livelihood. Environmental sensitivity  analysis for OSCP only do two early stages of OSCP scope, which integrated with the dangers of coastal vulnerability. This analysis mapped environmental component from oil pollution become sensitivity rangking as an effort to support response development strategies and priorities for the coastal resources protection. The aims of this research were (1) to establish environment sensitivity rank and (2) to identify primary factor supporting the environmental sensitivity for OSCP in south Delta Mahakam area. The result of analysis showed environmenal sensitivity was 62.37% (517.52 km), its mean very high sensitivity. Then the high sensitivity criteria was 11.31% (94 km). The criteria of medium sensitivity was 11.92% (99 km). While for low sensitivity and very low sensitivity respectively were 1.78% (15 km) and 12.64% (105 km). Based on Principal Component Analysis (PCA), 36.01%  variability was explained by axis of factor 1. The others variability 18.53% and 13.93% were explained by axis of the factor 2 and factor 3. Axis of factor 1 for coastal exposure (EK), oil residence index (OR), coastal type (TP), and biological resources (SH) had a quite large linear combinations coefficient, amounted to 0.94 (EK&OR), 0.83 (TP) and 0.75 (SH). This indicated a very high contribution for environmental sensitivity OSCP level drafting. On axis of factor 2, the linear coeffisien combinations for the resource utilization of port (PL) was 0.83 and settlement (PM) was 0.85. Axis of factor 3 contributed 0.75 and 0.66 on migas platform (PO) and placement of passive fishing gear/catchment area (AT). However, the utilization of coastal resources for PL, PM, PO and AT were on axis of factor 2 and factor 3 had a considerable distance with its SI variable. This possible caused by each variable percentage distribution which the value was very minor ranged 0.001-0.52%, so its not representated coastal resources elements closeness with SI variable in the study area.Keywords: Environmental Sensitivity, Oil Spill Contingency Plan, Mahakam Delta

Abstract

In general, natural resources capable of generating foreign exchange, such as: gas, petroleum and various other minerals are found in locations that have high productivity. Conditions of waters that have high productivity serves to support the sustainability of biological resources (e.g.: fish, mangroves, seagrass beds, seaweed and coral reefs). The government in this case the Ministry of Environment and Forestry (formerly the Ministry of the Environment) actually has made the signs of a rule that must be met by business actors who conduct activities in sensitive areas to environmental changes. PT. Total E & P Indonesia (TEPI) located in Balikpapan has long been engaged in exploration and exploitation of oil and gas in the Mahakam Delta. The large flow of branches of the Mahakam River empties into the Mahakam Delta provides a promising business opportunity for the farmers to open their business. While TEPI has oil wells are scattered in the delta area, pipelines are needed to collect the oil from the wells to the processing site. Because of the large number of streams causing many oil and gas pipes to cross the river (river cross pipes) that require special handling and meet the standards of technical rules and environment set by the government to be safe from passing boats or fishing boats that pass at the location. This study was conducted to predict the extent of exposed areas of exposure, especially the TSS concentration generated from the dredging activities in the pipeline. The simulation results show that the area of impact (TSS> 80 mg / L) is 74275.13 m2 dominantly moving westward from the dredging location (RC-06 = River Crossing Pipe No. 6). The farthest distance of the affected river body (TSS> 80 mg / L) to the west is 557.00 m from RC-06. The farthest distance of the affected river body (TSS> 80 mg / L) to the northeast is 240.81 m from RC-06. The farthest distance of the affected river body (TSS> 80 mg / L) to the southeast is 216.98 m from the RC-06 location. There is no water mass with TSS> 80 mg / L entering the pond. Sedimentation due to dredging activities is not accumulated and has no impact on shrimp farming business. The results of this study is expected to make a scientific basis in helping solve the problem of compensation requested by the farmers to TEPI due to decreased tambak production.
