This project aims to design and develop a propulsion system for agricultural equipment using RFID technology and evaluate its movement performance on different surfaces, including concrete and grass. The experiment focuses on examining the tag detection range under transmission power levels of 20 dBm, 23 dBm, and 26 dBm, as well as the impact of antenna angles on detection efficiency. Additionally, the system was tested in three movement scenarios: straight path, left turn, and right turn, at distances of 2 meters, 4 meters, and 6 meters. The results indicate that the system achieved the highest average speed of 0.4736 m/s and an average turning angle of 91.6° when moving in a straight path on a concrete surface at a distance of 4 meters. On a grass surface at the same distance, the average speed was 0.4483 m/s, with an average turning angle of 91.1°. For left and right turns, the movement on the concrete surface generally exhibited a higher average speed than on grass, particularly at a distance of 4 meters, where differences in turning angles were observed. This study provides insights into the factors affecting the movement of agricultural mowing equipment and serves as a foundation for enhancing the efficiency of propulsion systems in future developments.
ปัจจุบัน เทคโนโลยี RFID (Radio Frequency Identification) ได้รับการใช้งานอย่างแพร่หลายในหลากหลายอุตสาหกรรมและแอปพลิเคชันที่เติบโตอย่างรวดเร็ว เทคโนโลยีนี้ใช้คลื่นวิทยุในการระบุวัตถุที่ติดแท็กโดยไม่จำเป็นต้องมองเห็นหรือสัมผัสโดยตรง ทำให้การติดตามและระบุตำแหน่งมีความแม่นยำ คุ้มค่าทางเศรษฐกิจ และสามารถทำงานได้อย่างมีประสิทธิภาพในสภาพแวดล้อมที่หลากหลาย เช่น ภาคอุตสาหกรรมและการเกษตร ในภาคการเกษตร การใช้ RFID มีข้อดีหลายประการ เช่น ความสามารถในการทำงานกลางแจ้งโดยไม่ต้องพึ่งพาเซ็นเซอร์ราคาแพงหรือระบบสะท้อนสัญญาณที่ซับซ้อน ซึ่งช่วยลดต้นทุนและเพิ่มความแม่นยำในการควบคุมอุปกรณ์ทางการเกษตร งานวิจัยนี้มุ่งเน้น การออกแบบและพัฒนาระบบขับเคลื่อนต่อพ่วงอุปกรณ์ทางการเกษตรโดยใช้เทคโนโลยี RFID เพื่อศึกษาการเคลื่อนที่ของระบบบนพื้นผิวที่แตกต่างกัน ได้แก่ พื้นปูนคอนกรีตและสนามหญ้า โดยมีการติดตั้งแท็ก RFID บนเสาของแต่ละแถวเพื่อช่วยระบุตำแหน่งและทิศทางการเคลื่อนที่ของระบบ ผลการศึกษานี้จะช่วยให้เข้าใจข้อดีและข้อจำกัดของการใช้ RFID ในภาคการเกษตร ซึ่งสามารถนำไปต่อยอดเพื่อพัฒนาเทคโนโลยีการเกษตรให้มีประสิทธิภาพและลดต้นทุนในอนาคต

The concept of building a friendly city for older people by adjusting the physical environment is considered one of the crucial components of promoting older people’s better health and quality of life. Based on this tenet, designing a suitable footpath and considering older people’s needs are vital to the reduction of risks and the increase of safety in travelling, especially for older people living in Wat-Thad and Wat-Klang communities where the proportion of the elderly has continuously, increased. The research aimed to 1) survey the physical environment of footpath, approaching public assistance, 2) observe the elderly’s behavior and satisfaction on footpath in communities, and 3) create the proposal concept in developing the suitable footpath with the elderly’s need in city area. This research used various tools, including the questionnaire on the footpath’s physical environment to analyse problems, limitations, and footpath potentials, the interview of staff in the Engineering Division, Khon Kaen municipality and the questionnaires collecting travelling behaviour, satisfaction and attitude of elderly on the footpath in community. The data analysis the physical environment following six components in the monitoring list showed three used descriptive statistics. Interestingly, from 370 samples, the results of investigating qualified evaluations, namely 1) land utilisation in the communities, 2) linking the transportation network, and 3) beautifully attractive places for walking. However, three unqualified evaluations were 1) safety footpath availability, 2) design for all people, and 3) walking on the footpath to access public assistance and facilities. Moreover, the results from the questionnaire to study older people’s travelling behaviour, indicated that the most travelling objectives were grocery shopping and accessing the recreation sites with frequent visits three to five times per week. Furthermore, older people’s satisfaction with the community footpath was overall at a high level, This research proposed suggestions for developing a safe footpath to ensure safe walking access to facilities and public assistance.

This research gives a comprehensive overview of the use of antibiotics in livestock production, highlighting both the benefits and the risks associated with their use. The benefits, such as improving immunity, digestion, and reducing infections, are contrasted with the growing concern over antibiotic residues and the development of drug resistance. The shift towards alternatives like probiotics is explored as a sustainable solution, with a specific focus on lactic acid bacteria (LAB) found in the digestive systems of livestock. Thailand’s regulations, which control antibiotic use in animal feed, are also discussed, setting the stage for the study on LAB as a potential replacement for imported probiotics. 1. Use of Antibiotics in Livestock: Antibiotics have been used to promote growth, improve digestion, and prevent infections in livestock. However, the improper use of antibiotics can lead to residues in animal products and the development of drug-resistant bacteria. 2. Global Trends in Antibiotic Use: Many countries, like the European Union and Japan, have banned antibiotics as growth promoters, while others, like China and the U.S., are planning similar bans. 3. Thailand's Approach: Thailand has implemented a regulation since September 2020 to control the use of antibiotics in animal feed, requiring control at both feed mills and farms that mix their own feed. 4. Probiotics as an Alternative: Probiotics, particularly lactic acid bacteria (LAB), are being studied as an alternative to antibiotics. LAB are naturally found in the digestive tracts of livestock and are considered beneficial for maintaining gut health and replacing the need for antibiotics. The study examines the potential of LAB from Thai livestock (broilers, pigs, and cattle) as a sustainable alternative to imported probiotics, aiming to overcome issues like low survival rates of foreign probiotics in practice.
