Abstract

Tides are the rise and fall of sea levels due to the gravitational force of objects in the sky, especially the sun and moon, on the mass of sea water on earth. Semarang waters are located on the north coast of Central Java, which is one of the important coastal areas in Indonesia. This location is located between several large ports and sea trade routes, so information about sea tides is very important for navigation activities and port operations. This research uses tide data in Semarang waters from January to February 2018. The data collection technique was carried out in two ways. The methods used are secondary data and primary data. Secondary data is data obtained from direct surveys carried out by the Hydro Oceanographic Survey Unit Team in certain water areas. Meanwhile, primary data is a complement to secondary data that supports this research, namely using the admiralty method. The research results show that the type of tide in Semarang waters is a single daily tide (diurnal tide) with a formzahl value of 3.94.

Abstract

Abstrak Pasang surut merupakan naik turunnya permukaan air laut akibat adanya gaya gravitasi benda-benda di langit, khususnya matahari dan bulan, terhadap massa air laut di bumi. Letak perairan Semarang sangat menarik untuk dikaji mengenai karakteristik dan kondisi pasang surut air laut, informasi tentang pasang surut air laut berguna untuk kegiatan pelabuhan. Data yang dianalisa dilaksanakan pada periode tanggal 12 Januari hingga 9 Februari 2018 di Perairan Semarang. Teknik pengumpulan data dilakukan dengan dua cara, yaitu menggunakan data sekunder dan data primer. Data sekunder merupakan data yang diperoleh dari survei langsung yang dilakukan oleh Tim Satuan Survei Hidro-Oseanografi pada wilayah perairan tertentu. Sedangkan data primer dari Pushidrosal, merupakan pelengkap data sekunder pendukung penelitian yaitu dengan menggunakan metode A. Hasil penelitian menunjukkan bahwa jenis pasang surut di perairan Semarang merupakan pasang harian tunggal (diurnal) dengan nilai formzahl sebesar 3,937. Nilai elevasi pasut MSL sebesar 1,83 m, HHWL sebesar 2,51 m, dan LLWL sebesar 1,13 m.
