Abstract

According to the definition of International Hydrographic Organization (IHO) M-13 2005, the LowestAstronomical Tide (LAT) is Internationally used as chart datum, which is used as instruction for measuring thevalidation of high water surface in the Hydro-oceanography survey. It is predicted by tide prediction for 18.61years. This research is observed minimized in one year. In determining of LAT, it will be analyzed by the tideConstanta and prediction analysis.The analysis of tide Constanta will be calculated by the Rayleigh numberingmethod (the smallest quadrat), start on tide data observation for one month, two months, three months, fourmonths, six months until twelve months data of tide observation. Afterward, from that analysis results of t ideConstanta, it can be predicted the tide for 18.61 years. From this result, the prediction will be found thedifference of the LAT value of tide data less than in one year with tide data in one year. Then, from thedifference of LAT values can be analyzed at a significant level by using the statistical approach. From the resultof the LAT calculation by using data observation of tide in one year will be got the LAT position that is 43.3 cm.If comparing with LAT value which uses a variety of data less than in one year, it will result in the level ofsignificant differences. In this case, LAT value thas is calculated by data less than in one year cannot beequated with LAT which is used by observation of tide data in one year.Keywords: LAT, Tide Component, and interval of tide observation.

Abstract

Repair and Maintenance facility Jakarta is supporting facility component of Indonesian Naval Fleet which has duties to maintain and repair the ships that location is very strategics in Naval Base I. This is as KRI berth and technical condition preparation before doing the operation. The purpose of this research is to determine alternative strategy and roadmap for developing Fasharkan Jakarta with using TOWS analysis (Treaths Opportunities Weaknesses Strength) and ISM (Interpretative Structural Modeling). According to result of TOWS matrix analysis, SO strategy is consisting of eight strategic, four strategic for ST, nine strategic for WO, and four strategic for WT. Based on Weighting by using EFAS and IFAS matrix, WO strategy is as the choosen strategy, as the result WO strategy is become the first alternative. According to the elements clarification results for WO strategy, it gets five levels hierarchy. In this hyrarcy structure can be known that WO8 and WO9 sub strategies are in the level five position, then WO7 sub strategy in the level four strategy. Besides, in the level III is consist of WO5, in the level II is sub strategy WO1, WO3, WO6 and in the level I there are WO2 and WO4 sub strategies. Keywords: Repair and Maintenance Facility Jakarta, Developing Strategic, TOWS and ISM.
