This research presents a Digital Twin of an Aquarium for Water Quality Monitoring, developing a virtual model that displays real-time key water parameters, including pH level, temperature, flow rate, and dissolved oxygen. Sensor data is processed and visualized through a Graphical User Interface (GUI) to reflect the real-time status of the virtual aquarium. This system enables accurate water quality monitoring and analysis while reducing reliance on expensive software solutions.
มีเป้าหมายในการสร้าง Digital Twin ของตู้ปลา เพื่อใช้เป็นกรณีศึกษาในการตรวจสอบคุณภาพน้ำ โดยนำเซ็นเซอร์ตรวจวัด ค่าความเป็นกรด-ด่าง (pH), อุณหภูมิ, อัตราการไหลของน้ำ และออกซิเจนละลายน้ำ มาประมวลผลและแสดงผลผ่านอินเทอร์เฟซกราฟิกแบบเรียลไทม์ ระบบนี้สามารถใช้เป็นสื่อการสอนด้าน คอมพิวเตอร์ช่วยงานเทคโนโลยีการผลิต โดยไม่ต้องพึ่งพาซอฟต์แวร์ราคาแพง ซึ่งช่วยลดต้นทุนและเพิ่มโอกาสในการศึกษา Digital Twin อย่างมีประสิทธิภาพ

This study aims to develop a board game for teaching Integrated Farming System and to examine the learning achievement of third-year vocational certificate students at Ratchaburi College of Agriculture and Technology who used the board game as a learning tool. The research instruments included a board game developed using the Educational Boardgame Design Canvas. The board game is a strategic planning game consisting of five game boards, and 166 cards categorized into four types: 30 event cards, 60 special action cards, 16 character cards, and 60 production cards. It also includes 180 resource tokens of six kinds: 60 water tokens, 60 soil tokens, 45 plant product tokens, 45 animal product tokens, 45 aquatic product tokens, and 45 currency tokens. Additional components include one die and five player aid sheets. The game emphasizes planning and decision-making in integrated farming to maximize production and achievement points under game conditions and simulated scenarios. Research tools also included pre-and post-tests and a satisfaction questionnaire. The results indicated that students’ average scores significantly increased at the .05 level after using the board game, with the average pre-test score at 6.54 and the post-test score rising to 17.71. Additionally, an analysis of student satisfaction with board game-based learning revealed a high level of satisfaction (mean score = 4.45). The highest-rated aspects were the teacher’s implementation of post-tests (mean score = 4.69) and the engaging and diverse teaching methods used (mean score = 4.66).

This project focuses on developing a test device for an AC charger for electric vehicles according to the IEC 61851-1 Annex A standard by simulating the test circuit inside an electric vehicle according to the standard to test the operation of the AC charger. The test topic is related to the communication between the electric vehicle and the charger via a Pulse Width Modulation (PWM) control circuit system and creating an operation manual (WI) to prepare for testing in accordance with ISO/IEC 17025 standards, which are general requirements for laboratory capabilities in conducting tests and/or calibrations. The overall picture of this project is to develop test equipment and create an operation manual by collecting knowledge and various devices and then comparing the data to meet the abovementioned standards to test the Type II AC charger in each state. The test equipment consists of a communication part between the test equipment and the AC charger using a PLC S7-1200 and an HMI to control the operation of the switches in the test equipment circuit, including controlling parameters and displaying results. The equipment used to measure values is an oscilloscope and a multimeter that have undergone a calibration process to comply with the specified standards.
