Multi-Branch Centralized Dormitory Management System

2025-07-27T06:46:33+07:00

Managing multi-branch dormitories often encounters limitations related to fragmented data management, redundant information, and lack of system integration, all of which hinder service efficiency and centralized control. This research aims to develop a centralized web-based dormitory management system to enhance administrative efficiency across multiple branches without requiring multiple user accounts. The system is designed to reduce data redundancy and prevent errors caused by decentralized operations. Key functionalities include dormitory data administration, user management, rental contract processing, water and electricity billing, invoice generation, payment tracking, and branch-specific reporting. The system also implements role-based access control for administrators, managers, staff, and tenants. Development was conducted using the Laravel framework in conjunction with a MySQL database. Descriptive statistics, including percentage, mean, and standard deviation, were employed to analyze user feedback across six aspects : usability, accuracy, completeness, system efficiency, security, and satisfaction in system-based data management. The results of system development found that the system effectively fulfills its intended objectives. It enables centralized dormitory data management across multiple branches under a single user account and successfully supports all core functions as initially analyzed and designed. The system’s effectiveness was evaluated by a group of administrators, organizational staff, and domain experts. The evaluation results indicate that the developed system successfully fulfilled all predefined objectives, achieving a performance rating at a very good level. The average score was 4.60, with a standard deviation of 0.61. Notably, a significant contribution of this research is the centralized dormitory management capability across multiple branches through a unified platform. This reflects both technological advancement and a design approach that effectively addresses the limitations and inefficiencies inherent in conventional decentralized systems.

Simulation Model for the Productivity Improvement by Line Balancing: A Case Study of Roll Cake Product Group

2025-07-31T08:56:40+07:00

This research aims to minimize total employee working time, enhance production productivity, and improve the operational efficiency of the roll cake production line. The research methodology began with collecting data on the production process to analyze the cycle time and identify inefficiencies or waste within the system. The ECRS technique was applied to enhance work processes and achieve a balanced production flow. The situation was simulated using the Arena program to evaluate the results of the improvement. The study found that after improving the roll cake production process, the number of employees was reduced from 21 to 15, resulting in a labor cost reduction of 700,800 baht per year. Production line efficiency increased 14.5%, 22.82%, and 23.05%, while labor productivity rose to 90%, 81%, and 92% for roll cake production in Groups A, B1, and B2, respectively. Employee working time was reduced by 162.45 minutes per day, resulting in an annual labor and energy cost savings of 1,768,096.50 baht. It demonstrates that the application of the aforementioned technique can significantly improve the efficiency of the production system.

Design and Development of an Information Technology Prototype for Management and Forwarding Assistance for Aging Society Problem

2025-09-01T09:31:46+07:00

This research study aims to develop a prototype information system for managing elderly social problems in Ubon Ratchathani Province. Currently, relevant agencies manage problems through their individual processes and maintain separate databases, which leads to operational obstacles for integrated problem-solving and strategic planning. The prototype system was developed as a web application following the software development life cycle, utilizing C# and .NET Framework in conjunction with a Microsoft SQL Server database system. The system can record, monitor, and analyze data in an integrated manner across different areas, while incorporating statistical data presentation processes and visual display capabilities to support strategic decision-making. The system's performance was evaluated by experts, and user satisfaction was assessed through questionnaires that underwent validity verification. The study findings revealed that: 1) the prototype system can effectively support integrated data management and enhance senior management decision-making processes through visual data presentation; 2) the performance evaluation results were at an excellent level (mean = 4.61, standard deviation = 0.69), and users expressed excellent satisfaction levels (mean = 4.69, standard deviation = 0.72).

Analyzing Logistics Costs Using the Activity-Based Costing Approach for Sustainable Agriculture: A Case Study of Turkish Tobacco Cultivation in Roi Et Province

2025-07-16T13:48:57+07:00

This research is a study of logistics costs using an activity base cost system. Case Study of Turkish tobacco cultivation Roi-Et province with the aim of studying the logistical costs of the cultivation of Turkiz tobacco. Using analysis with activity base cost systems as a practice to reduce the logistics costs of farmers. Study Area Si Somdet District Roi-Et Province The samples studied were Turkice tobacco growers. Using a specific method of selection, turkice tobacco growers. In total, 50 cases showed activity in the cultivation of Turgiz tobacco. It consists of 6 main activities: 1. Planting preparation activities, 2. Planting activities, 3. Maintenance activities, 4. Harvest activities, 5. Transportation activities, and 6. Other activities for logistics costs according to the base cost system, the overall activity base of farmers cultivating Turkiz tobacco per rai area is 6,100 baht per cultivation season, with the highest cost being in the maintenance activities. The total cost is 1,900 baht per cultivation season, which is 31.15% the second is harvesting activity. The total cost of 1,400 baht per cultivation season is 22.95% of the total cost of planting preparation activities. Transportation activities cost a total of 1,200 baht, representing 19.67 percent of planting activities and others with total costs of 300 and 100 baht respectively. Farmers' logistics cost reduction practices should be used in conjunction with the use of chemical fertilizers, which reduces the consumption of chemical fertilizers and pesticides, which reduces costs, and local farmers should be included to help grow and help harvest renewable tobacco to provide lower labor costs and reduce unnecessary resource consumption.
