The effectiveness (E) of the subsidized fuel distribution for fish carrier vessels in Banjarmasin Fishing Port, Indonesia during 2017 and 2018 was investigated. A total of 58 respondents were interviewed using the structured questionnaires. The fuel distribution is locally managed by "Saraba Usaha" Cooperative. The total fuel consumption in 2017 (957,197 L/year) was 1.3 times higher than in 2018 (729,650 L/year). The total incomes received by the Cooperative in 2017 and 2018 were IDR 4,929,554,250 and IDR 3,757,697,500 respectively. The fuel distributed appears to still be inferior to the target quota, and falls between ‘fairly effective’ (E = 53%) and ‘ineffective’ (E = 49%). For the time being, the greatest user of the subsidized fuel was the large vessels. It is necessary to adjust the fuel allocation ratio between large, medium and small vessels to increase the effectiveness rates. The strategy for improvement of Cooperative business performance was further discussed.
