【 摘 要 】

Recently, a lot of marine resource management in this area such as shipping lane, Suramadu Bridge, Tanjung Perak Port, Teluk Lamong Port and other ports in Gresik and Bangkalan. According to the Law No. 32/2004 about local government stated that cities/regencies have full authorities to manage the sea untill 1/3 provincial authorities up to 12 nautial miles and then changed to the Law No. 24/2014, the authority of marine resource management is the provincial government up to 12 nautical miles from baseline. Regency and city governments just to get sharing of marine managed by province up to 4 nautical miles from baselines. The baseline as referenced in Law No. 32/2004 is low water line (LWL) and high water level (HWL) in Law No. 23/2014. The problem is maps (topographic map and nautical chart) which is used in this area were not referenced by HWL. Therefore, in this paper, we used SPOT 7 imagery to determine HWL in this area. After that, boundary of marine resource management is determined by median line and equidistance methods. Median line is used to determine maritime boundary between opposite cities/regencies (Surabaya - Gresik and Bangkalan) and equidistance is used to determine between adjacent cities/regencies (Surabaya and Gresik). The results of this study indicate that Surabaya, Gresik and Bangkalan have the right to earn sharing of marine resource management in the shipping lanes, Teluk Lamong Port and Suramadu Bridge. In this case, the change of Law No. 32/2004 to Law No. 23/2004 had an impact on the maritime boundary such as Surabaya getting loss of 70.844 ha, Bangkalan getting loss of 407.705 ha and Gresik benefit of 331.003 ha.
