One of the challenges in developing the system was the limited space available for excavation, as well as the need to extend the air\u2019s contact time with the pipe surface. The team addressed this by designing a serpentine pipe system with five bends and a vertically layered, multi-layer stratification configuration.<\/p>\n\n\n\n
Differences in pipe diameters were also utilized to optimize airflow characteristics based on the principles of continuity and Bernoulli\u2019s Law. The design aims to improve heat exchange efficiency without relying on high-power compressors.<\/p>\n\n\n\n
ADEM is equipped with a ventilation system featuring a turbine driven by a DC motor and powered by solar panels. The system maintains air circulation, including under low-wind conditions. Temperature sensors at the inlet and outlet continuously monitor temperature changes in real time and transmit the data to an ESP32 microcontroller, which regulates the ventilator\u2019s operation according to environmental conditions.<\/p>\n\n\n\n
\u201cWe designed this system to be adaptive. When the outdoor air temperature rises, the need for air circulation also increases. Under conditions with higher solar intensity, the solar panels can generate more power to support the operation of the ventilator,\u201d said Abdurrasyid.<\/p>\n\n\n\n
Unlike conventional cooling systems that rely on refrigerant compression and require relatively high electrical power, ADEM uses ground-based heat exchange as the initial cooling stage. Solar energy supplies the ventilation system, thereby reducing reliance on electricity from conventional sources.<\/p>\n\n\n\n
According to Syahril, the development of ADEM demonstrates FMIPA UI students\u2019 ability to integrate physics concepts with technological engineering. The project combines an understanding of thermodynamics and fluid mechanics with the development of electronic systems and data-based testing.<\/p>\n\n\n\n
\u201cStudents demonstrated multidisciplinary competencies by connecting physics theories, such as thermodynamics and fluid mechanics, with applied electronic systems engineering. Another strength lies in their ability to validate the concept computationally and conduct empirical field testing,\u201d said Syahril.<\/p>\n\n\n\n
The implementation of the 2026 PKM-KC program has currently reached approximately 90 percent completion, with 89.82 percent of the allocated budget utilized. The team has also disseminated the development results through social media and mass media. On September 15, 2026, the team participated in the national stage of the program online.<\/p>\n\n\n\n
The official announcement of the teams advancing to the 2026 National Student Scientific Week (PIMNAS) has not yet been released. The ADEM team hopes to advance to the next stage, taking into consideration the achievement of the program\u2019s outputs, the completeness of its documentation, and the testing data collected.<\/p>\n\n\n\n
Following the completion of the PKM-KC program, ADEM\u2019s development will continue in the Department of Physics at FMIPA UI, utilizing the facilities of the Parangtopo Laboratory and Electronics Laboratory. The next stages will include performance testing in an enclosed space (enclosure testing), optimization of the control algorithm, and plans to file a patent application. The team is also preparing scenarios for implementing ADEM in various types of buildings, including residential buildings, educational facilities, places of worship, community spaces, and green buildings. This development is aimed at evaluating the application of ground-temperature- and solar-energy-based cooling technology as an alternative approach to reducing the energy requirements of building cooling systems.<\/p>","protected":false},"excerpt":{"rendered":"
