Abstract

Seulawah Agam is one of the volcanoes for geothermal energy development with an estimated 150 Mwe. At the exploration stage, thermal and multispectral image analysis is needed for surface temperature calculations, subsurface temperature modeling, and geothermal potential mapping of volcanoes. In this study, we used Landsat 8 and DEMNAS data to analyze the distribution of potential geothermal areas in the Seulawah Agam. Based on analysis of Fault Fracture Density (FFD) from DEMNAS, three classifications reflect the distance of the fault, namely low level (0 - 0.30 km/km2), medium (0.30-0.60 km/km2), and high (0.60-0.90 km/km2), where the distribution of geothermal potential is at medium and high-density levels. Meanwhile, the NDVI, NDWI data analysis shows dense vegetation areas on volcanoes and relatively rare in some manifestations. It can also be confirmed well by the high-temperature distribution in some craters between 34.63 C to 46.59 C. Based on observational data. It shows that DEMNAS and Landsat 8 data are very potential to be used as an initial method of analyzing the distribution of geothermal potential on the Seulawah Agam volcano.

Abstract

An Online Geographic Information System (SIG-Online) has been successfully designed to strengthen the potential of gampong (village) as a form of community service at Gampong Meunasah Mesjid Lampuuk. The problem of partners so far is the lack of information about the importance of Gampong potential so that partners experience limitations in knowing access to information about the potential of the gampong. The stages in building a GIS Online system begin with planning, analysis, design, implementation and maintenance. SIG-Online will later display Gampong potential data and Gampong information equipped with geospatial data such as satellite image basemaps of the Gampong area, Gampong boundaries, gampong layout and population data of the Gampong community and its natural beauty. Technical stages in building SIG-Online start from data collection, processing, digital analysis and displaying SIG-Online on android applications by utilizing the internet network. In the process of building SIG-Online, community service collaborates with the non-governmental organization (NGO) Prodeelat. The output of this service is to provide convenience for partners in accessing the potential of gampong through the SIG-Online system so that there is an increase in peace and welfare in the community (village).
