Development of Hospital Management Information System for Optimization of Web and Mobile Based Patient Services

Alfin Fahreza — 2025-12-28

This study focuses on the development and implementation of a Hospital Management Information System (HMIS) aimed at optimizing web and mobile-based patient services. The research explores how the integration of advanced digital technologies enhances patient satisfaction, reduces service times, and minimizes administrative errors. Employing a quasi-experimental design, the study compared the performance of an experimental group utilizing the HMIS with a control group using traditional systems. Results indicate significant improvements in all key areas, highlighting the effectiveness of HMIS in improving healthcare service quality. This study contributes to the growing body of research supporting the adoption of digital solutions in healthcare management.

Implementation of IoT System for Household Electrical Energy Monitoring

Putra Mahendra — 2025-12-29

This study investigates the effectiveness of implementing an IoT-based system for household electrical energy monitoring to promote energy efficiency and user engagement. Using a quasi-experimental pre-test/post-test design, the study compared the energy consumption, engagement levels, and energy awareness of two groups: an experimental group utilizing the IoT system and a control group relying on traditional energy monitoring methods. Data were collected through real-time energy usage logs, user surveys, and observational records over a 12-week period. Results revealed a significant 20% reduction in energy consumption for the experimental group, compared to a negligible 1.28% reduction in the control group. Additionally, participants in the experimental group reported higher levels of energy awareness and actively engaged with the system, with 85% responding to alerts and 92% frequently checking real-time data. These findings confirm the effectiveness of IoT systems in optimizing household energy usage and promoting sustainable practices. However, challenges such as behavioral inertia, system usability, and data privacy require further attention to ensure widespread adoption. This study underscores the potential of IoT technologies to transform residential energy management and contribute to global energy sustainability goals.

Supply Chain Process Optimization with IoT Technology to Improve Logistics Efficiency

Ishaq Rahman — 2025-06-13

The integration of Internet of Things (IoT) technology into supply chain operations has the potential to significantly enhance logistics efficiency. This study investigates the impact of IoT on logistics optimization by focusing on key performance metrics such as on-time delivery, inventory accuracy, and fuel consumption. Data from various companies that have implemented IoT solutions in their logistics operations were analyzed. The results reveal a substantial improvement in on-time delivery (from 75% to 95%), inventory accuracy (from 80% to 98%), and a 20% reduction in fuel consumption. However, challenges such as high initial costs, system integration difficulties, and data security concerns were also identified. The findings confirm that while IoT offers considerable benefits in terms of operational efficiency and cost reduction, successful adoption requires overcoming technical and organizational barriers. This study contributes to the growing body of literature on IoT applications in logistics and provides valuable insights for companies considering IoT-driven supply chain optimization.
