KAJIAN KENAIKAN MUKA AIR LAUT DAN TINGGI GENANGAN (ROB) PADA TAHUN 2023, 2028, DAN 2033 DI KOTA SAUMLAKI, KABUPATEN MALUKU TENGGARA BARAT
Saumlaki is located in Southeast Maluku Regency, precisely on Yamdena Island. The city is located in the coastal area which makes it in direct contact with external conditions such as tides. The subduction of the Indo-Australian and Eurasian plates is located in the northwest of Saumlaki, makes its sea level more vulnerable to changes. The objective of this research is to determine the substantial of sea level rise based on the analysis of tidal data in 2014-2018 and to predict the height of tidal inundation in 2023, 2028, and 2033. The method used in this research is the quantitative method based of case study. This research uses Saumlaki tidal data that was obtained from BIG, which is then processed to obtain monthly and annual Mean Sea Level values. Based on the research, it is known that the rate of sea level rise in Saumlaki is 3.75cm/year and belongs to the type of Mixed Semi-Diurnal with Formzahl numbers in 2018 = 0.602, MSL value = 383cm, LLWL value = 226.4cm, HHWL value = 541cm, and the value of ZO = 314cm. Inundation prediction in Saumlaki in 2023 = 175.75cm, in 2028 = 194.5cm, and in 2033 = 213.25cm.
