The Sustainable Energy and Green Technology Applications (SEGTA) program has once again embarked on a community engagement mission. Hosted by the Faculty of Advanced Technology and Multidiscipline (FTMM), this international initiative reflects a strong commitment to achieving the United Nations Sustainable Development Goals (SDGs). On Sunday, August 10, 2025, SEGTA conducted activities in Kalianget and Gili Iyang, Sumenep, Madura, drawing participation from 91 individuals, including international students and faculty. This year’s efforts centered on six targeted projects in the Sumenep region.
The projects included: Solar-Powered Hydroponics: A Solution for Enhancing Food Security and Reducing Reliance on Fossil Fuels; Coconut Tree Planting to Preserve Oxygen Quality in Gili Iyang, Education Outreach; Empowering Students through Electric Mobility and Renewable Energy Education, Real-Time Air Quality Monitoring: Toward a Green and Sustainable Gili Iyang Island, Drone Applications; Green Technology, and Policy for Supporting Sustainable Tourism; and Maintaining Solar Shelters to Ensure Renewable Energy Quality in Gili Iyang.
According to Prof. Dr. Retna Apsari, M.Si., FTMM’s Vice Dean for Research, Innovation, Community Engagement, and Partnerships, the Kalianget program concentrated on the solar-powered hydroponics project. Hosted at a melon greenhouse operated by Bumdes Setia Makmur in West Kalianget Village, the event featured sessions by Rizki Putra Prastio, S.Si., M.T., a lecturer in Robotics and Artificial Intelligence Engineering, and Dr. Tri Siwi Agustina, S.E., M.Si., from UNAIR’s Faculty of Economics and Business.
While differing from conventional hydroponic systems, Prastio explained that the greenhouse could greatly benefit from Internet of Things (IoT) integration. Drawing from a project in Ngerong, Pasuruan, he noted that IoT combined with solar power can significantly boost crop yields for vegetables such as bok choy and lettuce. Effective implementation, however, would require aerial mapping through drone-based photography.
Meanwhile, Tahta Amrillah, S.Si., M.Sc., Ph.D., a Nanotechnology Engineering lecturer at FTMM and coordinator of the Coconut Tree Planting initiative, oversaw the planting of 20 coconut saplings at Green Island Gili Iyang—a newly developed green tourism site. Coconut trees serve dual purposes: providing ecological benefits such as windbreaks and coastal protection, and offering substantial economic value through their diverse byproducts. The planting was carried out symbolically and involved international student representatives.
Another SEGTA innovation this year was the promotion of biofertilizers—organic fertilizers derived from naturally occurring microorganisms through the fermentation of organic waste. These biofertilizers improve plant growth and enhance soil fertility without harmful chemicals. The SEGTA team also trained local residents in biofertilizer production and application, empowering them to use the method in their own farms.
The initiative aligns with SDG 13 (Climate Action) and SDG 15 (Life on Land), furthering Gili Iyang’s vision as a model for green tourism.
As part of the Real-Time Air Quality Monitoring program, Dr. Agus Mukhlisin, S.T., M.T., deployed technology to track oxygen and carbon dioxide levels in real time. “Accurate, real-time oxygen monitoring is essential for understanding environmental health. With this data, communities can better appreciate the need to maintain Gili Iyang’s high oxygen levels,” Dr. Mukhlisin said.
The monitoring device was installed at the Bancamara Health Center on Gili Iyang. It provides direct readings of oxygen concentration (%vol) and carbon dioxide levels (ppm). As of Sunday, August 10, 2025, the system recorded oxygen levels at 20.89%. This effort reflects FTMM’s commitment to SDG 13 (Climate Action) and SDG 11 (Sustainable Cities and Communities).
