Abstract

The waters south of Java to Nusa Tenggara are a critical upwelling region heavily influenced by monsoon dynamics. The interactions drive oceanographic variability, specifically Ekman Mass Transport (EMT) and Ekman Pumping Velocity (EPV), which regulate primary productivity. While previous studies have examined these dynamics, most have focused on short-term variations. To address this, this study analyzes the variability of EMT and EPV over a 22-year period (2003–2024) and their interaction with El Niño-Southern Oscillation (ENSO) and Indian Ocean Dipole (IOD). EMT and EPV values were calculated using ECMWF wind data, SST, and chlorophyll-a data sourced from MODIS, and climate indices (Niño 3.4 and DMI), which were then analyzed using Pearson correlation. Results show that EMT and EPV peak during the Southeast Monsoon (JJA), reaching approximately 5.16 m²/s and -2.89 × 10⁻⁵ m/s, respectively. Notable anomalies occurred in 2010 and 2016; specifically, the 2010 interaction between La Niña and a negative IOD significantly suppressed upwelling. Correlation analysis reveals that SST is predominantly influenced by EPV, while chlorophyll a concentration is more closely linked to EMT. Although both ENSO and IOD modulate these dynamics, the IOD exerts a stronger influence due to the region’s proximity to the Indian Ocean. These findings provide critical insights into the oceanographic drivers of regional productivity, supporting sustainable fisheries management.

Abstract

Tabbinjai Village is susceptible to landslides due to high rainfall, steep topography, and human activities. This study aims to determine the zone of landslide vulnerability using geophysical data and satellite imagery to generate a level of landslide vulnerability map in Tabbinjai Village. The AHP (Analytical Hierarchy Process) method is used to determine the weight composition of satellite imagery data, and Seismic vulnerability and slip plane identification are geophysical methods that include the HVSR (horizontal-to-vertical spectral ratio) method and the Wenner-Schlumberger configuration, respectively. Based on the AHP method, landslide susceptibility is classified into low (60.67%), moderate (37.89%), and high (1.44%) susceptibility zones. These spatial findings are supported by the in situ seismic vulnerability index (Kg) and geoelectrical resistivity profiles, confirming the strong likelihood of slope failure in critical areas. Therefore, integrated satellite imagery and geophysical data provide a reliable reference for regional spatial planning and disaster mitigation strategies.
