TVU – On June 27, the School of Engineering and Technology organizes the final round of the 2023 “Green Creative Ideas” contest at Campus 1, Tra Vinh University, with over 100 attending students.
The contest consists of two rounds, with more than 15 entries. In the preliminary round, four outstanding works are selected to advance to the final round. The contestants comprise students from the Faculty of Engineering and Technology and the Lab School (TVU).
During the final round, Dr. Phạm Quốc Phong, Vice Dean of the School of Engineering and Technology, states, “The contest for green creative ideas among students is a practical activity that encourages students to engage in learning and research. It aims to promote awareness, responsibility, behavior change, and community involvement in protecting the environment.”
The first prize is awarded to the idea titled “A device to kill brown planthoppers with integrated solar cells,” authored by Thạch Minh Trọng, a student of the Automotive Technology University 2020.
The second prize is awarded to the idea of a “Smart mini vacuum cleaner,” developed by a group of authors including Trương Dũng Liêm, a student of Class 3A from Lab School (TVU), and Giang Quốc Huy, a student of the Information Technology 2021.
The third prize is awarded to the idea of an “Information garbage collection boat,” created by Châu Nhĩ Thái and Nguyễn Hoàng An, students from the University of Technology and Mechanical Engineering, Class of 2021. Additionally, a Consolation prize is given for the idea of an “Automatic vacuum cleaner” by Huỳnh Quý Duy, a 2021 Mechanical Engineering Technology student.
Regarding the operation of the “Solar battery-integrated brown planthopper” device, Thạch Minh Trọng, a student from the Automotive Technology University 2020, shares, “The planthoppers begin functioning at dawn, at 6 a.m. The charge control circuit remains open for 2 hours (9 a.m. – 11 a.m.), and the LED lights are activated according to the control circuit, attracting the brown planthoppers. The timer circuit operates in a cycle of 3 seconds on and 20 seconds off. The device draws power from the solar panel, storing it in the battery through the control panel. A voltage drop circuit reduces the voltage from 12V to 3.7V. The device utilizes 3V LED lights and a mosquito racket circuit to discharge electricity into the 3V grid, effectively eliminating brown planthoppers.
