Along with the increasing population, the need for energy will also continue to grow. For that, efforts to look for new energy sources should be more intensively conducted. Therefore, innovations and ideas related to the energy sector should always be developed. This is done by a team of students of Engineering Geology ITB force 2015 which consists of Rio, Betari Ayu Pramita, and Fernaldy Sebastian Santoso. Rio and the team follow the Geothermal Future Energy Summit: GFEST 2017 and won first place in the event. This event is organized by the Indonesian Earth Collection Association Student Section UPN “Veteran” Yogayakarta. In the event that took place on Saturday-Sunday (21-22 / 10/17), Rio and his friends were able to win the first place because they succeeded in determining the potential area to be used as a geothermal field in Matangnga, Polewali Mandar, West Sulawesi.

Geothermal Field Determination

To determine the potential of the geothermal field, Rio and the team used geostatistical analysis. In this analysis, we analyze the Hg element in the form of ordinay kriging in the form of dry gas. The Hg element is used because it can give a sign of the occurrence of fractures below the earth’s surface. The presence of elements of Hg on the surface of the earth can illustrate that in the bowels of the earth there is a connection between fractures that occur. The result of the analysis on the Hg element is implied as a permeability zone.

Furthermore, the geostatic method which has been carried out is combined with the straightness density analysis on the surface. This method of surface density analysis is known as the Fault and Fracture Density Method (FFD). Through this FFD method, we can describe zones that have high structural density values. These results have close links with cesarean and fractures that occur in the area.

From the results of the compilation of both methods in the observed region, geothermal prospects can be obtained in the Matangnga region. Not only to the determination of the prospect area, Rio and his friends also managed to determine the catchment area and the output area. This area is an important component in the sustainability of geothermal potential in the region.

In the face of this race, Rio admitted experiencing various challenges. Rio feels his team’s preparation in the presentation phase is still less than the maximum. However, Rio and the team still have the confidence and enthusiasm to keep learning from the mistakes and shortcomings that exist within the team. With this spirit, Rio and the team managed to bring home the award as the first champion. Rio also felt very happy because it can represent the Geological Engineering ITB in a national event. Not only that, Rio is also pleased to be able to contribute in providing advice for Indonesia’s energy security. “As a geology student, I am happy to be able to contribute to Indonesia’s energy security”, he concluded.
