Abstract

Serang City exhibits a high level of seismic vulnerability due to its tectonic position near the convergent boundary between the Indo – Australian and Eurasian plates. Additionally, the local geological conditions, which are dominated by alluvial deposits, make seismic waves more susceptible to amplification and resonance, thereby increasing earthquake hazard potential. The objective of this research is to identify site class characteristics and calculate surface PGA values to assess seismic threat levels in the urban area. The data used include ground acceleration values from microzonation maps, local geological information, and regional seismic parameters. The analysis was conducted by classifying site conditions based on the average shear wave velocity to a depth of 30 meters (Vs30), and by estimating surface PGA values using local amplification factors. The results indicate that most areas of Serang City are classified as SE site class (soft soil), followed by SD site class (medium soil), predominantly in the southwestern part of the city. Surface peak ground acceleration values range from 0.84 to 0.91 g, which are considered very high. These findings suggest that all six districts in Serang City–Serang, Cipocok Jaya, Taktakan, Curug, Kasemen, and Walantaka–are at significant seismic risk in the event of an earthquake. Therefore, appropriate risk mitigation strategies are essential, including the reinforcement of spatial planning systems, the design of earthquake – resistant structures, and the development of more detailed seismic microzonation maps.

Abstract

Pengetahuan tentang pasang surut sangat penting untuk berbagai kegiatan manusia di perairan, termasuk transportasi laut, operasi pelabuhan, dan pembangunan infrastruktur di daerah pesisir. Pengamatan dan analisis pasang surut di Perairan Serang dilakukan pada bulan Oktober 2024. Pola pasang surut ditentukan dengan memanfaatkan tabel konstituen harmonik dan parameter dasar seperti amplitudo dan fase untuk mendapatkan bilangan Formzahl (F). Penelitian ini menggunakan data AWS (Automatic Weather Station) milik Badan Meteorologi Klimatologi dan Geofisika (BMKG). Hasil analisis menunjukkan Perairan Serang memiliki nilai Formzahl sebesar 0,719142866 dan digolongkan pada tipe pasang surut Campuran Dominan Ganda (Mixed Tide). Pola pasang surut Perairan Serang pada bulan Oktober 2024 sangat dipengaruhi gravitasi bulan dan matahari.
