Abstract

Accurate elevation determination is one of the crucial aspects in oil and gas exploration activities, especially in the planning and management of well areas. This study aims to identify and compare the elevation of the Digital Terrain Model (DTM) obtained from aerial photography with terrestrial measurements, and to convert Digital Surface Model (DSM) data into DTM. The urgency of this study is driven by the need for accurate, efficient, and economical mapping methods, as well as validation of the methods used in topographic mapping. Digital Terrain Model (DTM) is a virtual model that adds elements such as fault lines and observations to correct artifacts from the original data, while DSM includes the height of all objects on the ground surface. The results showed that the largest elevation value in the aerial photo DTM was 14.416 meters at point L06 and the smallest elevation value was 6.567 meters at point A46, with an average elevation of 13.716 meters. Meanwhile, the comparison results of DTM elevation of aerial photography with terrestrial measurements showed the largest difference of 5.513 meters at point A46 and the smallest difference of -2.682 meters at point L21, with an average difference of 0.072 meters. The level of vertical accuracy (Z) based on the LE90 value is 0.2076 meters, which meets the geometric accuracy standard of 1:1000 class 1 scale according to BIG Regulation Number 15 of 2014. The results of this comparison are also supported by a 3D model of DTM elevation of aerial photography. This study provides an important contribution to the validation and improvement of the efficiency of topographic mapping methods based on aerial photography, as well as providing an overview of the accuracy of the data produced.

Abstract

Aerial photo measurement aims to provide a real, fast, and interactive representation of the Earth's surface. Various methods of aerial photo acquisition and correction can be applied to obtain accurate results. The primary objective is to produce photos that present reliable and precise information consistent with actual conditions. A commonly used method in aerial photo mapping is the utilization of unmanned aerial vehicles (UAVs). The correction methods applied include direct correction, known as the Real-Time Kinematic (RTK) method, and post-processed correction, known as the Post-Processed Kinematic (PPK) method. This study aims to identify the highest horizontal orthophoto quality based on the Indonesian Geospatial Information Agency Regulation (BIG) No. 6 of 2018 concerning RBI map accuracy, by comparing the RTK and PPK methods, as well as variations in flight altitude during UAV data acquisition. The research conducted in Lemo II Village, Teweh Tengah District, North Barito Regency, Central Kalimantan Province revealed that the highest horizontal orthophoto quality was achieved using the PPK correction method at a flight altitude of 120 meters, with a horizontal RMSE value of 0.048 meters and an accuracy of 0.073 meters, which meets Class 1 standards at a 1:1000 scale. These values were obtained from tests conducted on 15 ICP points. Additional tests performed to determine the significance of model and method differences indicated that variations in flight altitude and photo correction methods have a significant impact on horizontal orthophoto quality.

Abstract

Coal is one of the main energy sources and the largest contributor to national revenue; however, its management faces challenges related to limited availability and accuracy in reserve estimation. An essential aspect of mining management is monitoring the Run of Mine (ROM) volume, which plays a critical role in crushing, washing, and blending processes. This study aims to compare the accuracy of ROM volume measurements using Terrestrial Laser Scanner (TLS) and Unmanned Aerial Vehicle (UAV) methods in the production area of PT FAD, Berau Regency, East Kalimantan. A quantitative descriptive approach was employed, involving field data acquisition, three-dimensional modeling, and volume analysis using specialized software. The results show that ROM volume measured with TLS was 1,407.669 lcm, while UAV produced 1,387.357 lcm, with a difference of 20.312 lcm or 1.45%. This deviation is within the ASTM D6172-98 tolerance limit (<2%), indicating that both methods are valid. Although TLS offers higher accuracy, UAV is more effective and efficient in terms of measurement time, making it a reliable alternative for modern mining monitoring. This study provides practical insights for the mining industry in selecting ROM volume measurement methods that are not only accurate but also efficient in supporting sustainable operations and data-driven decision-making.

Abstract

A bathymetric survey is an activity aimed at depicting the depth contour lines of a water body, encompassing measurement, data processing, and visualization stages. Conducting a bathymetric survey in shallow waters, such as reservoirs, estuaries, lakes, dams, or sedimentation areas, often presents challenges when using large vessels. One of the technologies for performing bathymetric surveys in shallow waters is the use of an Unmanned Surface Vehicle (USV), which facilitates data collection while offering flexibility, efficiency, and effectiveness. The study aims to produce a bathymetric map from bathymetric measurement data using a USV (Unmanned Surface Vehicle) corrected with real-time tidal data and to determine the data quality order according to the IHO (International Hydrographic Organization) S44 Edition-6 Standard of 2022.

Abstract

Stunting remains one of the major chronic nutritional issues in Indonesia. According to the 2021 Indonesia Nutrition Status Study (SSGI), the national stunting prevalence reached 24.4%, while in West Sumatra Province it was recorded at 25.2% in 2022. Although Padang City showed a significant decrease to 3.7% based on 2023 e-PPGBM data, continuous intervention is still necessary. Various socioeconomic factors such as parental education, family income, number of children, and household size have been shown to influence the incidence of stunting. However, spatial-based approaches to analyze the distribution of stunting cases at the local level remain limited. This study aims to map and analyze the spatial pattern of stunting in Padang City using Geographic Information Systems (GIS). This method enables a geographic visualization of case distribution, supporting more targeted policy decisions. The findings of this study are expected to provide accurate spatial data to strengthen integrated and sustainable efforts in stunting prevention in urban areas.

Abstract

Mount Marapi is one of the active volcanoes in West Sumatra, which erupted on December 3, 2023, followed by heavy rainfall that triggered a cold lava flood. This event caused damage to land, infrastructure, and vegetation around Sungai Pua Subdistrict, Agam Regency. This study aims to analyze vegetation density changes before and after the lahar event and to map the affected areas using Sentinel-2 satellite imagery, applying the Normalized Difference Vegetation Index (NDVI) and spatial overlay methods. The results show a decrease in very dense vegetation from 623.127 ha (42.38%) to 199.095 ha (13.54%), and an increase in poor vegetation from 354.269 ha (24.09%) to 551.566 ha (37.50%). The total vegetation density change reached 734.03 ha out of 1,470.32 ha. Identification of affected areas also indicates that the lahar spread along river channels from the summit to the slopes, with an affected area of 110.832 ha. These areas include agricultural land, plantations, and settlements along the riverbanks that were damaged by volcanic materials.
