In the process of geothermal power plants, it is necessary to drill wells to take hot steam from inside the earth to rotate the power plant turbines. In its operation, these steam wells need to be maintained through workover activities. From drilling and workover activities resulting in drill cutting which becomes a problem because it cannot be disposed into the environment. In one drilling campaign program, 200-300 tons of drill cutting were produced which could not be disposed into the environment. For this reason, the best way to manage drill cutting waste is to use it for its own needs, so that the volume of waste is reduced. Based on the results of the study, the appropriate use of drill cutting is to use it as raw material for making bricks and concrete roads, because the processing is low cost, absorbs quite a lot of local manpower and the results can be used for internal purposes such as buildings, roads, drainage, and other infrastructure projects, so that economic, social and environmental benefits can be obtained at the same time. The drill cutting processing method is very simple starting with the drying process by drying it to reduce the water content, then drill cutting that has been dried mixed with cement in a certain formula, then printed into bricks and concrete roads which are then dried for the hardening process. Based on the use of drill cutting in the Gunung Salak geothermal power plant, this drill cutting utilization method has succeeded in reducing drill cutting to 100% so that it is not a problem for the environment. During the running time monitoring is done by monitoring wells, especially along concrete roads and the results show good parameters. From the results of the strength test, the brick and concrete roads produced from drill cutting have a strength that meets Indonesia National Standards (SNI).
