ANALYSIS OF UTILIZATION CHLOROPHYLL-A CONCENTRATION DATA FROM REMOTE SENSING IMAGERY TO SUPPORT MARITIME SECURITY OPERATIONS (CASE STUDIES IN THE ARAFURA SEA)

Abstract

Indonesia is the largest archipelago in the world with a vast ocean area and the richness of the fish. It allows the
occurrence of crime at sea, for example, is a crime of theft of fish and other marine resources. Indonesia in the
regard Indonesian Navy confronted with various obstacles, among others, the limitation of the number of patrol
boats that are not proportional to the extent of waters that should be on the cover as well as the limitations of
the available budget for operational activities in the framework of the implementation of law enforcement
operations related crime at sea. With the limitation of that than required effectiveness and efficiency in
operations to crime at sea can still be implemented and the richness of the sea remains awake.The utilization of
remote sensing satellite technology capable of delivering information quickly with a broad scope. This research
use the MODIS Aqua Image data Level 2 to detect the distributions of chlorophyll-a concentration which is an
indicator of the fertility of the waters of an area the area is closely connected with the fisheries through the
implementations process of bottom-up areas with transparent high fertility rate is an area that's prone to fish
theft crime occurred. From the result of the data processing MODIS-Aqua Satellite image pattern time and
location of the concentration of chlorophyll-a and verified by VMS data indicate that there is a close relationship
where a times and areas with a high concentration of chlorophyll observed a lot of fishing activity, so it is used in
this research can be used as supporting data in determining the direction and timing of the operation in
particular operations against crimes the theft of fish, finally the marine security operations could become more
effective and efficient and success can be further improved.
Keywords: Sea area, chlorophyll-a, effective and efficient.
