The Earth is a dynamic planet whose surface continues to change due to various geological processes that have been occurring for billions of years. When plates in the Earth’s crust move, elastic energy accumulates at the plate boundary zone until it reaches a point where the roc…

The Government of Indonesia, mandated PT Hutama Karya to develop and manage Trans Sumatera Toll Road (JTTS), spanning 2,844 km of strategic toll road infrastructure. By 2025, approximately 848 km will be operational, necessitating robust maintenance and monitoring mechanisms to…

Monitoring water quality is essential for sustaining ecological balance and public health, particularly in urban rivers facing increasing anthropogenic pressures. This study examines the relationship between surface temperature and chlorophyll-a concentrations in the Tallo River…

On-screen digitization is a time-consuming and labor-intensive process that limits the efficiency of mapping, particularly when analyzing rural settlements with numerous objects. This study investigates the potential of the Segment Anything Model (SAM) to improve both accuracy a…

Point cloud data has become central to 3D modeling and digital twin development in architecture, engineering, and construction. While Light Detection and Ranging (LiDAR) offers high accuracy, integrating multiple sensor types for building-scale visualization—particularly for int…

Waqf land management in Bojonegoro Regency remains largely manual, resulting in difficulties in spatial mapping, limited transparency, and poor awareness of waqf asset potential. This study aims to develop a web-based Geographic Information System (WebGIS) called SI-TAWAF to dig…

Earthwork volume calculation plays a vital role in determining physical progress and validating payment claims in large-scale infrastructure projects such as the Trans-Sumatra Toll Road (JTTS). As the main contractor, PT Hutama Karya Infrastruktur is responsible for ensuring hig…

Service delivery efficiency remains a critical challenge in contemporary land administration systems worldwide, particularly in developing countries undergoing rapid urbanization and land tenure formalization. This study examines persistent service backlogs in measurement and ma…

Geothermal pipeline mapping is essential for asset management and integrity monitoring, ensuring early detection of failures and supporting energy resilience. Traditional terrestrial surveys, such as total stations and GNSS-RTK, are accurate but inefficient for networks spanning…

The Rakutai Segment of the Garsela Fault in West Java represents an active tectonic zone with persistent seismic activity. Throughout 2023–2024 a series of earthquakes was recorded, culminating in two notable events during 2024. The first, on 18 September 2024, reached 4.9 Mw an…

Drought is an event that threatens and disrupts human life as it is closely related to the availability of groundwater reserves. The availability of clean water has become a serious challenge due to arid climate conditions, low rainfall, and prolonged dry seasons. Ileape Timur S…

Evaluating road surface conditions is essential for infrastructure maintenance planning and asset management. Conventional methods are often time-consuming and inefficient, highlighting the need for more automated and precise approaches. This study aims to assess road roughness…
