State’s protection in citizen was in principally an obligation of the country. Therefore title of the
study that researcher wrote was protection of Indonesian country on citizen who settled in region
of United Country Republic Indonesia arrested by Malaysian. Indonesian country had a power
ruled at the region. It was also enacted by international law. Basically Indonesia should be able
to give a protection to all citizens of Indonesian country. Had Indonesian country’s protection on
Indonesian citizen within region of United Country Republic Indonesia who arrested by
Malaysian been implemented suitable to legal rule in Indonesia? The writer used a narrative law
research model that focused on positive law norms based on data search from literatures related
to Indonesian state protection towards its citizens who were in Republic Indonesia sovereignity
region whose were arrested by Marine Police Malaysia. Protection that Indonesia gave on citizen
was assessed less effective. It could be clearly seen, three observers in Sea and Fishery Resource
who arrested by Malaysian were just effort of releasing without presence of responsibility from
Malaysian side. Arresting three observer in Sea and Fishery Resource was done in region of
Indonesian country by Malaysian.
