Oil spill contingency plan (OSCP) by environmental sensitivity index (ESI) analysis at East Barito District, South Barito District and Kapuas District (Tamiang Layang, Buntok and surrounding area), Central Kalimantan Province

Abstract

The central Kalimantan has envolved into a new oil and gas industry area where potential impact on environmental need to be anticipated comprehensively for environmental protection from oil spill. The locations are East Barito District, South Barito District and Kapuas District (Tamiang Layang, Buntok and surrounding area), Central Kalimantan Province. The main problem of this study is determining areas of sensitive and vulnerability to oil spill. The aims of study were to identify the factors and components that affect the level of ESI to oil spill and analyse and establish environmental sensitivity rank for oil spill contingency plan. The methodology of study carried out by identifying and assessing each landuse unit and analyse performed by GIS method with ESI formula. Interpretation and classification of landuse used Landsat TM imagery that acquired in 2014 and updated in 2018 and field survey in October 2014. The result of analysis showed environmental sensitivity index divided into four categories, dominated by high sensitive (40,8%) due to the presence of protected and conservation forest, less sensitive (31,9%), moderately sensitive (14,6%), and insensitive (12,8%). General condition of study area is lowland and swamp area and potential to flood. The environmental protection from oil spill should be mitigated and prioritized for sustainable development.

Identification and Mapping of Environmentally Sensitive Areas of the Coastal Strip of Guilan Province

“…Regarding this differ- Despite the slight differences between the two studies, their research was conducted in 2014, so during this period, some locations or types of economic activities in the coastal strip have changed. Based on the study on insensitive areas, Hernawan et al [31] reported 12.8%, 31.9%, 14.6%, and 40.7% for low, medium, and high sensitivity categories, respectively. They showed that the river bank adjacent to the oil and gas block of Kalimantan Province, Indonesia, similar to the coastal strip of Guilan, allocates a large percentage to the high-sensitivity category.…”

“…The Nile Delta is very close to the Suez Canal and is one of the main oil transportation routes in the world. Hernawan and Risdianto [16] used the ESI to manage potential oil spills in the oil and gas production block of Indonesia's central Kalimantan province. Research data were obtained through field survey and satellite imagery and analyzed in GIS software.…”
