PENENTUAN BATAS WILAYAH LAUT PROVINSI JAWA TENGAH DAN JAWA BARAT MENGGUNAKAN DATUM GEODESI NASIONAL

Abstract

According to Minister of Internal Affair regulation which is Permendagri No.1 Tahun 2006, Peta Lingkungan
Laut Indonesia (LLN) must be utilized to define boundaries of province sea jurisdiction. Unfortunately, Peta
Lingkunan Laut Indonesia still applies Indonesia Datum 1974 instead of Datum Geodesi Nasional 1995. It is
contrary with Permendagri No 76 Tahun 2012 and UU No.4 Tahun 2011 which declare the urgency of single
reference datum for Indonesia region. To fit the requirement, Peta Lingkungan Laut Indonesia must be
transformed into official datum. This research applied two transformation formulae. There was Lauf
Transformations to accomodate 2 Dimension Transformation. Computation of transformation parameters and
application of those parameters were tested at North Coast of Java from Kendal regency to Brebes regency. As
calculated in MatLab software, this research concluded that Lauf transformation was good for transforming
Lingkungan Laut Indonesia from ID74 to DGN95.
