The Indonesia Education International Innovative Competition (IEI2C) 2021 has announced its winners! Students from the UGM Faculty of Engineering, namely Mayradaffa Ayudya (Mechanical Engineering), Rakhmat Eko Saputro (Nuclear Engineering), Resa Wardana Saputra (Chemical Engineering), Reyhan Faiz Barley (Engineering Physics), and Rizal Qoirul Mustofa (Mechanical Engineering), won a gold medal through their brilliant innovation in renewable energy. They designed a hybrid module of a floatovoltaic-wind turbine to address clean water problems in the coastal area of the Pacitan Regency.
The competition was held by the Indonesian Federation of Publishers of Research Innovation (IFPRI) online from May 25 to June 24, with 99 participants from various universities and high schools from within and outside the country. Under the supervision of lecturer and energy expert Ahmad Agus Setiawan, the UGM team elaborated their idea and composed a paper entitled Renewable Energy Technology Innovation: Floating Photovoltaic-Vertical Axis Wind Turbine as a Source of Energy Treatment Seawater Using Reverse Osmosis Method for Solution of Clean Water Problems in the Coastal Area of Beach, Pacitan Regency.
“The idea came up from clean water problems in coastal areas. We designed a renewable energy source from a floating photovoltaic-vertical axis wind turbine module to power up reverse osmosis-based water treatment in the said area,” explained team representative Resa on Tuesday (13/7).
According to Resa, Pacitan has what it takes to utilize solar and wind energy. The proposed system consists of three 1 m x 1.6 m solar panels and three Savonius-Darrieus wind turbines arranged in series. Based on the calculations, one module of floating photovoltaic-vertical axis wind turbine will generate 12.38 kWh/day and supply 1000 L reverse osmosis of 10 kWh/day requirement.
