Abstract

Data is an important thing as a base of an analytic or a hypothesis for concluding participant vote data in the Indonesian General Election. The data needs to be processed and secured, so the integrity of the data is in good condition. It also needs to protect the participant voting rights, so the information is correctly displayed. The research problems include creating a system that protects the integrity of election data and creating a system that protects election rights for each voter. Based on the problems, this research discusses a blockchain-based electronic voting information system that would secure the integrity of data and also protecting the participant voting rights in a General Election. The system uses Ethereum as a blockchain with Solidity as a programming language to build a smart contract and is built in Microsoft Windows platform. In this research, consortium blockchain and biometric fingerprint authentication are used as a problem-solving method, and waterfall steps is used as a system development method. The result of this research is a proposed design of the e-voting system. The conclusion based on this research is a blockchain-based e-voting system that secures the integrity of the data in a selection process and ensures protection to each vote right.

A company that has an optimal business processes and supported by an integrated information system will win the competition. This study aims to optimize the purchasing business process of Company XYZ using the concept of Business Process Re-engineering (BPR) approach as the basis for designing the next module of enterprise information systems. From this study, we found that there are still business processes that need to be revised and improved to integrate the flow of data and information from one department to another department. Business process that needs to be revised is an overseas purchase; Business processes that need to be improved are Overdelivery and Under-delivery Tolerance, PO Free Goods, PO Subcontracting, and Purchasing Planning consisting of Weekly Projected Sales, Weekly Order Projection & Daily Order Projection. Index Terms - Business Process Reengineering, Business Process Purchasing.
