Abstract

Jakarta merupakan kota yang berlokasi di pesisir utara Jawa dengan luas wilayah 66,401 ha. Secara topografis, Jakarta terletak di dataran rendah dengan kemiringan berkisar 0-5 derajat. Jakarta termasuk wilayah landai yang kemungkinan besar akan terdampak langsung dari fluktuasi kenaikan permukaan air laut. Fluktuasi air laut merupakan  masalah serius yang dialami negara-negara pesisir atau kepulauan di seluruh bumi termasuk Indonesia. Hal tersebut dapat mengganggu aktivitas pesisir sehingga perekonomian di Jakarta terganggu. Tujuan penelitian ini adalah untuk mengetahui besarnya fluktuasi tinggi permukaan laut di pesisir kota Jakarta kaitannya dengan fluktuasi tinggi muka air laut global. Penelitian ini menggunakan metode kuantitatif dengan menghitung laju peningkatan kenaikan fluktuasi permukaan laut melalui metode statistik regresi linier sederhana menggunakan Software Microsoft Excell. Hasil dari penelitian ini menunjukkan bahwa ada peningkatan permukaan laut di Kota Jakarta, yaitu berupa naiknya elevasi permukaan laut sebesar 0,1734 cm/bulan dengan fluktuasi permukaan laut yang meningkat signifikan, yaitu Jakarta sebesar 1,65 ± 0,34 cm/tahun, Lautoka  sebesar 0,91 ± 0,33 cm/tahun, Honiara 1,56 ± 0,59 cm/tahun, dan Port Vila sebesar 1,91 ± 0,36 cm/tahun, secara umum merupakan peningkatan yang sangat tinggi dan secara signifikan lebih tinggi dibandingkan rata-rata global sekitar 3,6 mm/tahun.

Abstract

The Indonesian Maritime Continent is highly vulnerable to climate variability and change, as exemplified by tidal flooding events in the Riau Islands from 2022 to 2024. This study aimed to analyze the characteristics of sea level dynamics and anomalies associated with tidal flooding (rob) and identify the contributing factors. Data on tidal flooding events were gathered from press and online social media reports, while additional information on significant wave height, ocean currents, and wind was obtained from the CMEMS (Copernicus Marine Environment Monitoring Service) Marine Copernicus archives (marine.copernicus.eu). Observational data from tide gauge stations were also accessed via the IOC sea level monitoring system (ioc-sealevelmonitoring.org). The findings revealed a high probability of tidal flooding during the north wind season, particularly in January and February. Notably, tidal elevations during flooding events reached 3.06 m on January 25, 2023, 3.00 m on February 21, 2023, and 3.09 m on February 12, 2024. These events were driven by a combination of oceanographic and atmospheric factors, including high tidal ranges during spring tides, strong wind speeds averaging 19.04 to 21.43 knots in January–February 2023 and 18.65 knots in February 2024, dominant southward current patterns, and significant wave heights reaching up to 1.08 m. The alignment of the sun, moon, and earth during full and new moon phases amplified gravitational forces, causing elevated sea levels. Furthermore, strong winds during the north wind season contributed to higher wave heights, intensifying flooding impacts. Analysis of current patterns indicates that the highest speeds were recorded during the northern wind season, specifically in January and February, which coincides with the tidal flooding events. The currents predominantly moved southward, aligning with the wind direction during this season. This study reveals oceanographic and atmospheric interactions driving tidal flooding, offering insights for mitigation and adaptation to enhance resilience in vulnerable coastal regions.
