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

The tourism industry is one of the most dynamic and rapidly growing economic sectors in the world. Every year, millions of tourists travel to various destinations around the world, bringing a significant economic impact to destination countries. Apart from contributing to national income and job creation, this industry also encourages cultural exchange and understanding between nations. In the research process, researchers design research designs to provide structure to research activities from beginning to end. This includes steps such as determining the research problem, formulating research objectives, asking research questions, choosing research methods, collecting and analyzing data, and formulating conclusions and research results. This system uses Google MapsAPI to determine distribution points in the Tourism Geographic Information System in Mandailing Natal Regency. The system that has been built makes it easy for users to access distribution points and related information regarding natural tourist attractions in Mandailing Natal Regency. A Geographic information system has been built which includes tourist location points, tourist descriptions, detailed images, news, events and visitor services.

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.

Abstract

This study aims to develop an artificial intelligence-based expert system to help diagnose skin diseases. This system is designed to help users, especially the general public, identify the type of skin disease based on the symptoms they experience. By collecting data from dermatologists and medical literature, this system is built using the forward chaining method. The system's knowledge base contains rules that link symptoms to certain skin diseases. System testing shows high accuracy in diagnosing various types of skin diseases, such as psoriasis, eczema, and fungal infections. With this expert system, it is expected to increase public access to skin health information and help early detection of skin diseases.

Abstract

Overstock and delays in fulfilling requests for spare parts at Hyundai Nagoya can occur due to ineffective stock management. The objective of this research is to develop a web-based platform warehousing system that increases the efficiency of goods rotation using the First In First Out (FIFO) method. In addition, the Random Forest algorithm is used to categorize components according to goods movement patterns. The movement patterns of goods are divided into three categories: fast moving, medium moving and slow moving categories. The data analysed includes order history, frequency of use, and stock of goods for the last six months. By implementing a web-based system, real-time stock monitoring and order recommendations based on historical demand patterns can be made. The study's findings demonstrate that the FIFO approach effectively lowers the chance of old products piling up, increasing recording accuracy, and speeding up spare parts distribution. With a classification model accuracy of 75%, this method can improve warehouse management and help make more accurate decisions. In conclusion, the FIFO method can be used in a web-based warehousing system to optimize spare parts stock management at Hyundai Nagoya. Keywords: FIFO, Hyundai Nagoya, Random Forest, Stock Management, Warehousing System
