Abstract

Total Suspended Solids (TSS) are defined as particles and materials suspended in water with sizes up to less than 2 µm. High TSS concentrations pose significant hazards by hindering light penetration, disrupting photosynthesis, and reducing oxygen levels in aquatic environments. Conventional TSS monitoring through laboratory tests is often inefficient regarding time, labor, and cost. Consequently, remote sensing technology provides a more efficient alternative for TSS monitoring in reservoirs. This study utilizes Landsat 8 satellite imagery to develop suitable empirical algorithms for estimating TSS concentrations in Gondang Reservoir, Lamongan. It aims to evaluate the spatial distribution of TSS over three years (2016, 2019, and 2022) and analyze changes in TSS conditions throughout these periods. The research employs a quantitative descriptive method, applying the Syarif, Parwati, and Guzman & Santaella algorithms. Results indicate a continuous increase in TSS concentrations annually, with the highest concentrations observed in the reservoir's inlet areas. Accuracy tests reveal a coefficient of determination (R²) of 0.71 for the Syarif algorithm, demonstrating its substantial accuracy in estimating TSS levels in Gondang Reservoir. This study underscores the worsening TSS conditions in the reservoir and highlights the effectiveness of remote sensing technology for environmental monitoring.

Abstract

While Mount Merapi's high eruptive activity poses severe rain lahar threats, there remains a critical gap in integrating comprehensive spatial risk assessments into accessible geo-education frameworks. This study addresses this void by evaluating the risk levels of rain lahar disasters to support spatial-based mitigation learning. The high activity of Mount Merapi has various potential eruption hazards, one of which is the danger of lava flows that can occur at any time and threaten the safety of the surrounding community. Therefore, this study aims to examine the level of risk of lava flow disasters on Mount Merapi. The spatial data and WebGIS platform generated from this study are specifically designed to enhance students' geospatial literacy and formulate place-based disaster preparedness education for local communities in high-risk zones. This research employs a quantitative spatial modeling approach utilizing Weighted Overlay Analysis and Spatial Multi-Criteria Evaluation (SMCE) within a Geographic Information Systems (GIS) framework. The data used is in the form of secondary data collected through literature study activities on various sources. Data processing techniques are used, namely remote sensing and geographic information systems, while in data analysis, risk calculation equations are used according to the Head of BNPB Regulation Number 2 of 2012. Based on the results of the study, it is known that the risk level of lava flow disasters is high in Srumbung District, Muntilan District, and Salam District. Efforts that can be made to respond to the high level of risk are to reduce the level of vulnerability through improving health facilities, education, evacuation, economic guarantees and mitigation systems; and increasing capacity through optimizing cooperation and coordination between parties.
