This research focuses on developing a system to reduce greenhouse gas emissions in internal combustion vehicle engines using electrolyte technology and embedded programming on an electronic board via the OBI protocol. The main objectives are to create a prototype, apply it in real-world scenarios, evaluate its efficiency, and facilitate technology transfer. The system, designed to reduce greenhouse gases from vehicles, consists of a Bluetooth on-board diagnostics (OBD) scanner connected to the electronic control unit (ECU). This scanner transmits data to an embedded microcontroller through a Bluetooth module. The microcontroller, which includes software for controlling oxygen measurement and production, operates to decrease greenhouse gas emissions. The results show that the electronic device, IC ELM327, decodes OBD into RS232, processes the oxygen output from the exhaust pipe using embedded programming on the Arduino Uno-R3 microprocessor, and controls the oxygen production unit with electrolyte technology. The system adds 9.82% oxygen to the exhaust and reduces carbon monoxide by 21.04% and carbon dioxide by 13.86%. Additionally, the technology transfer received high satisfaction with a mean score of 4.61, indicating efficient technology dissemination.

The primary aim of this paper was to research and develop a closed tunnel house hot air production system, focusing on cost reduction in the cold-pressed coconut oil production process. The study's scope was centered on a case analysis of Tropicana Oil Co. Ltd. situated in Sampran district, Nakhon Pathom province. The research encompassed the design of a system capable of generating hot air and conserving thermal energy within a closed tunnel house environment. This included developing and constructing a prototype system tailored to this purpose. One of the key objectives was to assess the system's efficiency within the closed tunnel house setup. The broader goal was to enhance air temperature while reducing moisture content before initiating the coconut drying process. It was achieved through an electricity-powered hot air-drying technique, the process aimed to efficiently eliminate water or moisture from dried coconut, priming it for the subsequent cold-pressed oil extraction phase. The resulting system is anticipated to yield multiple benefits. It's projected to curtail energy consumption for operators by minimizing temperature losses within the system. This is facilitated by augmenting natural heat to elevate the air and container temperature during baking. Furthermore, this research unveiled insights into the optimal tunnel house configuration as a highly effective heat source. It also advanced knowledge in creating low-humidity heat storage systems and measurement/control mechanisms tailored for specific tasks. These innovations are anticipated to have applications beyond the coconut oil industry, extending to other sectors reliant on heat energy for production processes.
