Abstract

The advancement of digital technology has created opportunities for efficiency in voting processes through e-voting system. However, the conventional e-voting systems are often vulnerable to cyber attacks and data manipulation. The main issue lies in the centralized architecture of these systems, which present significant security risks. This study explores the implementation of a more secured e-voting system built on blockchain technology, utilizing smart contracts on the Ethereum platform, that leverages the Proof-of-stake consensus with specific focus on vendor selection. By utilizing a decentralized architecture, the blockchain-based system eliminates single points of failure and distributes data across multiple nodes, significantly reducing the risk of manipulation or unauthorized access. This research concludes that the implementation of blockchain technology, especially that leverages the PoS consensus algorithm and smart contract on the Ethereum platform, can perform effectively and provide enhanced security compared to conventional e-voting systems.

Abstract

In the current era, coffee shops have become popular destinations for people to unwind while enjoying a variety of food and beverages. Nevertheless, conventional manual ordering systems often result in lengthy queues and operational inefficiencies. To overcome these challenges, this research focuses on developing an Android-based menu ordering application that utilizes QR Code technology combined with the First Come First Serve (FCFS) method. The application aims to streamline the ordering process for customers without requiring staff assistance while enhancing overall workflow efficiency. By employing QR Code technology, customers can view the menu directly on their devices, place orders, and send them digitally to the system. The FCFS method ensures that orders are processed in the sequence they are received, thereby reducing errors in service prioritization. The application was developed using the Waterfall model of the Software Development Life Cycle (SDLC), which encompasses stages such as requirements analysis, design, implementation, and testing. Testing outcomes reveal that the application significantly improves ordering efficiency, decreases waiting times, and increases user satisfaction. By adopting this system, coffee shops can enhance service quality, optimize operations, and provide customers with a more seamless and enjoyable experience.
