The UGM Fasttech team consisting of Ahmad Bikhari Hakim (D4 Engineering Management and Maintenance of Civil Infrastructure), Alfitra Heydar Achsan (S1 Engineering Physics), and Wisnu Hozaifa Hasan (S1 Mechanical Engineering) won first place in the Energy Idea Competition – International Science and Technology Fair 2021 held by Pertamina University and the Indonesian Engineers Association on 13 March – 30 June 2021.
Meanwhile, the Eco Engineer team consisting of Mayradaffa Ayudya (2019 Bachelor of Mechanical Engineering), Rakhmat Eko Saputro (2019 Bachelor of Nuclear Engineering), and Resa Wardana Saputra (2019 Bachelor of Chemical Engineering) won second place in the competition. This competition was held online with 47 teams participating from various well-known universities in Indonesia.
The UGM Fasttech team wrote a scientific paper entitled “Integrated Smart Microgrid Bladeless Vortex Wind Turbine-Photovoltaics Hybrid System: Renewable Energy Innovation for Optimization and Efficiency of Electrification in Urban Areas.”
Wisnu explained that the design was in the form of an innovative hybrid energy integration system based on wind turbines and solar panels with smart microgrid control. The wind turbine is a vortex bladeless wind turbine or a bladeless wind turbine with the principle of vortex-induced vibrations. Bladeless turbines can increase the efficiency of electricity production, which increases gradually with increasing wind speed, and has a starting point of generation at a lower speed than horizontal and vertical wind turbines.
According to Wisnu, the designed vortex turbine has an additional structure in three horizontal cylindrical rods at an angle of 1200 to support the solar panels. The solar panel attached to the cylindrical structure can rotate along with the movement of the cylinder connected to the servo motor, with the vertical and horizontal axis directions in line with the data input of the light intensity sensor. The two generators are integrated on a smart microgrid capable of electrifying housing, street lighting, and controlling with data analysis components in the forms of voltage sensor parameters, electrical loads, and the sun’s position.
“In the future, this innovation can be implemented and become a new solution and alternative for optimal electrification in urban areas as a new renewable energy production for the sustainability of Indonesia’s energy in the future,” said Wisnu, Wednesday (7/7).
Meanwhile, the eco engineer team wrote a scientific paper entitled “Floating Photovoltaic-Vertical Wind Axis Turbine on the Coastal Coast of Reka Village, East Nusa Tenggara as an Effort for Equitable Telecommunication in the 3t Region Based on Renewable Energy Sources.”
Resa explained that the idea to design this innovation originated from the telecommunications problems in Indonesia. One of the areas experiencing this problem is in Reka Village, Ende Regency, NTT. The proposed innovation is a renewable energy source system based on Hybrid Floating Photovoltaic-Vertical Axis Wind Turbine as an energy source for BTS tower power supply.
“This innovation consists of solar panels and a Savonius-Darrieus Wind Turbine type arranged in series. Three Hybrid Floating Photovoltaic-Vertical Axis Wind Turbine modules are necessary with 38.58 kWh/day of energy generated to supply 1500 Watt BTS energy,” said Resa.
This innovation would support the implementation of SDG 7 (Affordable and Clean Energy). In addition, it can also serve as a consideration for the development of other renewable energy in the context of optimizing electrification throughout Indonesia.
