WEBGIS-BASED ONLINE MULTI-HAZARD COASTAL MAPPING IN DEMAK REGENCY, INDONESIA
Demak Regency is a coastal area along the northern coast of Java that is increasingly exposed to environmental pressure from natural processes and human activities, resulting in coastal multi-hazards. Previous studies have mainly focused on single-hazard assessments and have not sufficiently integrated a multi-hazard approach. This study applies the Coastal Hazard Wheel (CHW) 3.0 method to identify coastal multi-hazard levels in Demak Regency and presents the results through an interactive WebGIS platform. The WebGIS system is developed as a single portal using ArcGIS Experience Builder. The system consists of a Home page built with ArcGIS StoryMap providing an overview of the study area and methodology, an Interactive Map using ArcGIS Web Map for spatial visualization of coastal multi-hazard distribution, a Dashboard presenting statistical information in graphical form, and a Usability Testing module using ArcGIS Survey123 to evaluate user experience. Evaluation was conducted through program testing and usability testing. Results indicate that all system functions operate properly across smartphones, laptops, and multiple web browsers without functional errors. Usability evaluation produced an average score of 4.66, categorized as excellent. The integration of CHW 3.0 and WebGIS is expected to support effective identification, visualization, and management of coastal multi-hazards in Demak Regency.

ORDINARY KRIGING GEOSTATISTICAL MODEL FOR LAND VALUE ZONING: A SPATIAL STUDY IN RANTAU PULUNG, EAST KALIMANTAN
Land is a crucial element whose use is closely tied to spatial planning and regional management. This study aims to estimate the distribution of land values in Rantau Pulung District, East Kutai Regency, using the Ordinary Kriging geostatistical method. The main problem raised is the limited information on land values in areas that lack sample points. Primary data were obtained from 343 sample points of land prices from field surveys, while secondary data in the form of administrative boundaries were used as spatial references. The analysis was carried out using ArcGIS software with a spherical variogram model, which was selected as the best approach based on cross-validation results. The mapping results show that the highest land values are around main road access and activity centers, while the lowest prices are spread across less accessible outlying areas. This finding confirms that accessibility and proximity to public service centers are dominant factors in influencing land values. This interpolation map can be used as a basis for spatial planning, zoning, and more efficient land management policies.
INTERPRETING SURFACE REPRESENTATION THROUGH COMPARATIVE ANALYSIS OF LIDAR-DERIVED TERRAIN AND SURFACE MODELS
Accurate representation of the Earth's surface is fundamental for geospatial analysis and environmental studies. This research examines and compares the Digital Terrain Model (DTM) and Digital Surface Model (DSM), both generated from LiDAR data acquired over the ITERA campus, a region characterized by heterogeneous land cover, including built-up areas, vegetation, and open ground. Data were collected using a DJI M350 drone equipped with an APUS sensor at an altitude of 100 meters. The methodology involved preprocessing point cloud data, classifying ground and non-ground points, and generating elevation models using Triangulated Irregular Network (TIN) interpolation with a 0.5-meter grid. Vertical accuracy was evaluated through 12 reference checkpoints measured with Geodetic GPS technology. Results demonstrate that the DSM achieved higher vertical accuracy, with a root-mean-square error (RMSE) of 0.060 meters, compared to the DTM's RMSE of 0.342 meters. Analysis of the normalized DSM (nDSM) revealed elevation differences of up to ±38 meters between DSM and DTM, effectively identifying vertical structures such as dense vegetation and campus buildings. These findings confirm the DSM is more reliable for analyzing the absolute heights of surface objects, while the DTM remains essential for modeling natural landforms, even in areas with complex land cover and greater uncertainty.
ANALYSIS OF EXISTING AND INDICATIONS AREA OF THE PANEMBONG LAKE, SERANG REGENCY, BANTEN PROVINCE
Indonesia is estimated to have more than 1,575 lakes, consisting of 840 large lakes and 735 small lakes (situ). As a source of raw water and flood control, lakes and reservoirs play a crucial role in maintaining the balance of land use and natural resources. This study will analyze the existing conditions and area indications of Situ Panembong by doing a Mapping/Topographic Surveying This study is expected to provide important contributions to the mapping and discourse on lakes in Indonesia, as well as information for maintaining Situ Panembong in Banten Province as a protected area. A key benefit of mapping the survey data in this study is that it can also summarize information from the field, allowing it to be used in planning. The method used in this research employs qualitative analysis. The technical measurement methods used in this activity include measuring land areas, topography, situation, longitudinal and transverse profiles, and aerial photography. The reasult is that Conditions in the Panembong Lake demonstrate a strong relationship between hydrology, land use, and socio-economic and industrial activities. Aerial mapping using digital photogrammetry technology produced several key products—orthophotos, DSMs, DTMs/topography, and 3D models. These results collectively provide an accurate spatial representation of the morphological conditions and physical characteristics of Panembong kae. The Digital Surface Model (DSM) shows elevation variations that encompass all surface features, including vegetation and anthropogenic structures. The extracted Digital Terrain Model (DTM) and topographic maps show a relatively gentle contour across the lake body, with a gradual increase in elevation toward the perimeter. These topographic characteristics confirm that the lake is located in a natural basin with a flow pattern that vegetates toward the center of the reservoir.
