Abstract

In this digital era, the tourism industry is one of the sectors that highly requires technology, such as the use of applications or websites, to remain competitive and reach a broader range of customer seeking tour and travel services. Tourism continues to grow rapidly alongside the increasing public interest in business, educational, or recreational travel. However, several challenges often arise in managing travel package sales, such as difficulties in booking processes due to limited accessibility, inefficient data management and a lack of flexibility in meeting customer needs. A structured system is designed using the Model View Controller (MVC) method to address these issues and meet the needs of both customers and companies effectively.

Abstract

The rapid development of information technology, particularly in the Internet of Things (IoT), creates significant opportunities for smart solutions like IoT-based gas leak detection systems. Given the widespread use of LPG cylinders in households, small businesses, and large industries, this research aims to design a gas leak detection tool utilizing detection sensors on LPG cylinders. This tool is intended to reduce the risk of danger or fire incidents, especially in industries and restaurants. The study focuses on designing and implementing an IoT-based gas leak detection system using key components like the MQ-2 sensor, which detects hazardous gas, and a buzzer that serves as an initial alarm. Notifications are also sent via the Telegram application for immediate alerts. Testing results demonstrate that the system effectively detects gas leaks and provides timely warnings through both sound alarms and Telegram notifications. The gas detection accuracy is notably high, making it a reliable solution for minimizing fire or explosion risks caused by gas leaks. All components—MQ-2 sensor, buzzer, NodeMCU connectivity module, and Telegram application—work cohesively, fulfilling the system’s design goals and ensuring smooth operation. This research underscores the importance of IoT technology in enhancing safety and mitigating hazards in daily environments.

Abstract

The development of computer technology encourages companies to adopt digital systems, including payroll systems. However, the Sendanu Darul Ihsan Village Office, Riau, still uses a manual Excel-based method, which often triggers errors such as incorrect NIK input and inaccurate salary calculations. This research project aims to create a web-based payroll system using a hybrid method, namely a combination of the Waterfall method and the CodeIgniter 3 platform. This application is designed with a Model-View-Controller (MVC) approach to facilitate data handling, using Sbadmin2 bootstrap which provides a responsive, modern, and easy-to-use front end. The waterfall technique ensures that development is carried out in a structured manner through the steps of analysis, design, coding, testing, and implementation. It is hoped that this method will reduce errors, speed up the payroll process, and increase the efficiency of the village office.

Abstract

The development of digital technology, especially the internet, has provided convenience in various activities, including e-commerce-based transactions. This research aims to develop an e-commerce application for Markibong, an online store that offers various souvenirs from Batam, such as food, souvenirs, and clothing.This application is built using the open source Android platform to improve the efficiency of marketing, sales, and transaction processes. The development process follows the Waterfall method in the Software Development Life Cycle (SDLC), including needs analysis to the implementation stage. With this application, it is expected to expand customer access and increase revenue for Markibong stores.

Abstract

This study explores the optimization of sales and inventory management for electronic products in e-commerce platforms by applying the FP-Growth algorithm within data mining techniques. Amid the rise of digital transactions, many businesses still struggle to uncover hidden patterns in consumer purchasing behavior. This research analyzes 163 transaction records collected through questionnaires, with 30 transactions selected as the primary sample. The FP-Growth method was chosen for its efficiency in identifying frequent itemsets without generating candidate sets, making it suitable for large-scale data analysis. Significant findings from this study reveal strong associations between certain products, such as the itemset “Refrigerator is frequently followed by Microwave” with a support value of 23% and a confidence of 92%, as well as “Washing Machine is often purchased together with Iron” with 43% support and 100% confidence. These results indicate that consumers tend to purchase these items together. Understanding these patterns allows businesses to design more targeted bundling and promotional strategies, while also improving stock management. This research offers practical insights for data-driven decision-making, ultimately enhancing sales performance and operational efficiency in the e-commerce sector.
