BANDUNG, itb.ac.id – Electrical Engineering students from the School of Electrical Engineering and Informatics (STEI) at ITB have developed a product called SGC (2025). This device is designed to regulate and control CO2 levels and light spectrum required by plants, based on setpoints inputted by the user. The product was showcased during Electrical Engineering Days 2025 (EEDays 2025), which serves as a culmination event where final-year undergraduate Electrical Engineering students publicly present their final projects, held on June 23–26, 2025, at the East Hall of ITB Ganesha Campus.
The students behind the product are part of Team TA242501008, consisting of Kadhan Dalilurahman, Elisabeth Frenata Situmorang, and Daven Darmawan Sendjaya, under the guidance of Dr. Ir. Irman Idris, M.Sc.
The creation of this product was inspired by feedback from research teams, particularly from SITH ITB, and several clients who noted that current chamber controllers are unable to simulate optimal conditions for plant growth. Specifically, there is a need to control the light spectrum to further study its effects on plant development or plant responses to certain lighting conditions. Additionally, CO2 regulation was deemed necessary, as chili plants tend to have yellow, thin leaves compared to those grown in a screenhouse environment.
The product planning began in September 2024, followed by the development phase in March 2025. The design was based on interviews with users (from SITH ITB) regarding desired features to be added to the chamber. Afterward, the group members integrated their individual components into a finalized product.
“The advantage of our product lies in the new control system: a customizable light spectrum controller that can adjust lighting across five spectral ranges — UV-A, Blue, Deep Red, Far-Red, and PAR,” said Daven.
Elisabeth explained that the CO2 controller allows for controlled gas supply or filtering, thereby creating a climate conducive to the plant’s needs. All control systems are supported by a user-friendly interface design, accessible via onsite interface, website, and mobile application, making it easier for users to manage the system.
“ITB’s academic environment supports us in terms of knowledge and collaboration. Moreover, several relevant courses in the Electrical Engineering curriculum — such as Control Systems, Microprocessor Systems, Network Software Planning, and Optoelectronics for learning about LEDs — greatly helped us,” added Kadhan.
The team hopes that with this product, people can grow various plants under different climate conditions tailored to plant characteristics. Additionally, they hope the product will benefit industries by boosting agricultural productivity and enabling efficient plant growth.
