Abstract

Digital voting systems have garnered significant attention in recent years due to their potential to increase accessibility and transparency in elections. However, concerns about security, transparency, and verifiability have limited their widespread adoption. This paper proposes a blockchain-based verifiable decentralized mechanism for digital voting systems, aiming to address these concerns. By leveraging blockchain technology, cryptographic techniques, and decentralized consensus, our proposed mechanism offers a secure and transparent platform for conducting digital elections. This paper outlines the architecture, components, and benefits of our system, highlighting its potential to revolutionize the way we conduct elections. The proposed mechanism incorporates advanced encryption algorithms to secure the privacy of individual votes. This privacy-centric approach safeguards voter anonymity while still allowing for transparent verification of the overall election results. Security analysis underscores the effectiveness of the blockchain-based verifiable decentralized mechanism in addressing key concerns surrounding digital voting systems. By leveraging innovative technologies and cryptographic principles, the proposed system exhibits a high degree of resilience, transparency, and protection against potential threats, making it a promising solution for secure and trustworthy digital elections.

Abstract

The continuous growth of private vehicle usage in Indonesia has led to a significant increase in fuel demand, making the strategic placement of gas stations a critical issue for transportation infrastructure planning. However, inappropriate site selection may result in uneven service coverage, affecting increased operational costs and reduced accessibility for road users. Therefore, a systematic and objective decision-making approach is required to support gas station location planning. Motivated by this challenge, this study develops an integrated decision-support framework to evaluate and select strategic gas station sites based on multiple criteria. The framework combines the Analytic Hierarchy Process (AHP) and the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) methods. The AHP method is employed in the first stage to determine the relative importance weights of the evaluation criteria based on expert judgments. In the second stage, the TOPSIS method is implemented to rank candidate locations and identify the alternative closest to the ideal solution. To validate the proposed framework, a case study involving multiple candidate locations is experimented with. Experimental results demonstrate that the proposed AHP–TOPSIS approach is a practical tool for selecting gas station site location, with location L3 identified as the most strategic site for gas station construction.
