Abstract. Environmental Sensitivity Index (ESI) is basically a measure of the
potential loss of economic, social , physical and biological value of the area (land or
water) . The ESI be prepared to determine the level of sensitivity and vulnerability
of natural resources in coastal areas. Now, coastal areas of Cilacap has very fast and
dynamic development and have vary diversity such as geophysic condition, biology,
shoreline type and landuse type. The coastal area of Cilacap also has very important
environmental services (as a recreation, transportation, source of energy, means of
education or research, residential , industry. Besides it has potentials for
development, this area is also had great potential to pollution especially pollution of
the oil. That is caused Cilacap has the rafinary oil plant and the great port of oil,
furthermore it has crowded traffic of ship (both big ship or fishing ships). All of
which have a tremendous potential pollute the sea and the surrounding areas.
Therefore, for protection and management planning in coastal area of Cilacap is
needed assessment and mapping of ESI. Generally, this assessment (mapping) of ESI
is used weight and scored each input parameter. Data input, analysis, edit, and
presentation of information use geographic infromation system technology
(software). Based on this study, in general coastal areas of Cilacap has “sensitive”
and “very sensitive” to the presence of oil spills (about 207 km 2 ), and the area that
has” less sensitive” and “insensitive” only in southern part of P. Nusakambangan.
Therefore, it need the act of prevention as early as possible to minimize the negative
effects which may arise due to the presence of pollution of oil
