Wilayah perairan Kepulauan Riau merupakan salah satu lokasi dengan tingkat kerawanan tindak pelanggaran di laut yang cukup tinggi di Indonesia, karena wilayah ini berbatasan langsung dengan negara tetangga dan merupakan jalur perdagangan dan pelayaran internasional. Salah satu peran dari TNI AL adalah menjaga stabilitas keamanan wilayah yurisdiksi nasional, termasuk di wilayah perairan Kepulauan Riau yang kemudian diwujudkan dalam Operasi Keamanan Laut, dimana dalam pelaksanaannya masih memiliki beberapa kendala yaitu keterbatasan anggaran, kemampuan teknis, jumlah kapal, keterbatasan informasi, serta keterbatasan sarana pendukung, sehingga pelaksanaan Operasi Keamanan Laut menjadi tidak optimal. Penyebab utamanya adalah penempatan kapal patroli selama operasi tidak tertata dengan baik. Dengan adanya permasalahan tersebut, maka diadakan penelitian dengan menggunakan metode set covering untuk mendapatkan lokasi penempatan kapal patroli yang paling optimal dengan kapal yang sesedikit mungkin namun tetap dapat menjangkau seluruh wilayah perairan Kepulauan Riau dan meminimumkan biaya operasionalnya. Dalam penelitian ini dilakukan pendekatan secara diskrit yaitu penentuan titik rawan yang berjumlah 37 titik rawan. Semua titik ini harus terjangkau oleh kapal yang bertugas.

In carrying out these basic tasks the Navy relies heavily on the readiness of the Indonesian Warship (KRI),including the readiness of underwater construction in KRI from corrosion attack on sea water. Nowadays, KRIuses Sacrificial Anode Cathodic Protection (SACP) from corrosion attack. Whereas, SACP system has someweakness, such as the lifetime protection is short. The aim of this paper is to the analysis of Impressed CurrentCathodic Protection (ICCP) design of the underwater structure of KRI using computative theory calculation andspecimen test. The results of ICCP design showed that the specimens I required 0.081 Ampere (A) forprotection current, specimen 2 required 0.010 A for protection current, specimens 3 required 0.00251 A. Withpotential protection between -800 mV up to -1100 mV, it described that the ICCP system is reasonable. Theresult of cathodic protection design towards an underwater structure of KRI (TR-40 Type) showed that 1.75 forAmpere (A) and 3.35 volt DC for voltage. The benefit of this paper is a reference standard in the planning of theICCP design at KRI.Keywords: Corrosion, Underwater Structure of Warship, Impressed Current Cathodic Protection (ICCP).

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.
