In the heart of Yogyakarta, Indonesia, a quiet revolution is brewing, not in the bustling streets, but in the serene irrigation canals that crisscross the landscape. Researchers, led by Iftitah Imawati from Universitas Islam Indonesia, have tapped into these waterways to generate clean, renewable energy, offering a glimpse into the future of decentralized power generation.
The team has developed a pico-hydro system, a small-scale hydropower generator, designed to harness the kinetic energy from flowing water in irrigation canals. “We saw an opportunity to utilize the existing infrastructure for a secondary purpose—generating electricity,” Imawati explains. The system, which uses an undershoot water wheel turbine made from galvanized plates and plastic, is a testament to ingenuity and sustainability.
The innovation doesn’t stop at power generation. The researchers have integrated an Internet of Things (IoT)-based monitoring system, enabling real-time tracking of generator output, battery voltage, and load current via a smartphone interface. This remote monitoring capability allows for optimized energy production and simplified performance tracking, making the system not just efficient but also user-friendly.
Field tests in Yogyakarta’s irrigation canals have proven the system’s mettle. The pico-hydro system demonstrated stable power generation, reaching an overall efficiency of 11.38%. The IoT monitoring system showed impressive accuracy, with generator voltage and load current measurements at 99.33% and 99.26% respectively. “The data transmission delay was minimal, averaging just 5.64 seconds,” Imawati adds, highlighting the system’s responsiveness.
The implications for the energy sector are significant. Pico-hydro systems like this could be a game-changer for off-grid communities, offering a reliable and renewable energy source. Moreover, the integration of IoT technology paves the way for smart, interconnected microgrids, enhancing energy management and distribution.
The research, published in the National Journal of Electrical Engineering (Jurnal Nasional Teknik Elektro), underscores the potential of small-scale hydropower in irrigation channels. As the world grapples with the dual challenge of energy demand and environmental sustainability, innovations like these offer a beacon of hope. They remind us that the solutions to our most pressing problems often lie in the most unexpected places—like the humble irrigation canals of Yogyakarta.
This research could shape future developments in the field by encouraging further exploration of decentralized, renewable energy solutions. It also highlights the importance of integrating advanced technologies like IoT to enhance system efficiency and user engagement. As Imawati and her team continue to refine their pico-hydro system, they are not just generating electricity; they are powering a sustainable future.
