Excessive use of paper waste during the general elections is a consumptive behavior and can damage the environment. In the 2018 Pilkada, there were 54 million unused ballots due to the lack of public participation in each Pilkada. In addition, various ballot manipulations make reduced data integrity. The Custom E-Voting Application is an electronic voting system application for general elections with the application of Blockchain technology to increase security using the Hyperledger Fabric and Hyperledger Composer platforms. The application of this technology can replace conventional paper-based voting systems and databases. This application uses a distributed database so that the database is more secure and maintained its integrity. The results of E-Voting can be seen by voters so that transparency for voters. This application can be implemented in several elections that require transparency of the results with the election time can be set as needed. The problem that is the focus of this research is the proof of the concept of blockchain technology with existing tools and system performance testing. It is hoped that the results of this research can provide an overview of the viability of blockchain technology to handle cases such as the general elections that are critical, massive, and simultaneous.
