Abstract
ABSTRAK Tujuan dilakukannya penelitian ini adalah mengkaji komponen dan tipe pasang surut, menganalisis perkembangan kedudukan muka laut di Perairan Semarang dalam 20 tahun terakhir, mengkaji nilai kenaikan muka laut Semarang akibat pemanasan global dan menganalisis nilai penurunan tanah di stasiun pasut. Penelitian ini bersifat deskreptif dengan desain studi kasus. Data utama yang dikumpulkan pada penelitian ini antara lain data pasang surut dan data penurunan muka tanah di stasiun pasut. Data-data tersebut kemudian dianalisa secara deskreptif, dijabarkan dalam bentuk tabel grafik dan peta kemudian dicari keterkaitan antar data-data tersebut. Hasil penelitian ini menunjukkan bahwa tipe pasang surut di perairan Semarang adalah campuran condong ke ganda, perkembangan kedudukan muka laut di Perairan Semarang yang tercatat di stasiun Pasut semarang mengikuti pola liner dengan persamaan Y =4,8967 X - 9645,9 (R2 = 0,9636) dan laju kenaikan sebesar 5,43 cm/tahun, kenaikan muka laut global mengakibatkan kenaikan muka laut di Perairan Semarang sebesar 2,65 mm/tahun, laju penurunan tanah yang terjadi di Stasiun Pasut semarang sebesar 5,165 cm/tahun. Kata- kata kunci : kenaikan muka laut, penurunan tanah, rob, Semarang ABSTRACT The purpose of this research are to study type and component of tide, to analyse the growth of mean sea level in territorial water of Semarang for the last 20 years, to study the value of sea level rise in Semarang that caused by global warming effect and to analyse the value of land subsidence in tide station. The character of this research is decreptive with case study desain. The main data that collected in this research are tide data and the land degradation data in tide station. Then the data are analysed descriptively, formulated in the tables, maps and graphs and also search the relation among those data.This research found that tide type in territorial water of Semarang was mixed tide prevailing semi diurnal, growth of mean sea level in Semarang water that been recorded in tide station Semarang followed linear patern with the equation was Y = 4,8967 X - 9645,9 (R2 = 0,9636) and the rate of increasing was equal to 5,43 cm / year, the value of sea level rise in Semarang water that caused by global warming was equal to 2,65 mm / year and rate of land subsidence in Semarang tide Station was equal to 5,165 cm / year. Keywords : sea level rise, land subsidence, rob flood, Semarang
