UNAIR NEWS – Three students majoring in Physics, Faculty of Science and Technology (FST) Universitas Airlangga succeeded in making ship propulsion machine as well as fishing vessel power plant by using technology based on eco-anemo magnetic, utilizing wind and magnetic power to produce a source of electrical energy at the same time as a ship engine propulsion.

The three creative students are Eduardus Oldi Kristianto, and two members Leni Manggarsari and Siti Nurmala. They are joined in the Student Creativity Program field of Invention (PKM-KC) category FST UNAIR.

Their success was written in a report entitled “Pro-Gensine (Propulsor and Generator Ship Engine) : An Efficient, Low-Cost and Eco-friendly Eco-Anemo Magnetic Based Fish-catching Boat Dual Machine ” passed the selection of Higher Education. Therefore, they got developmental fund from Ministry of Research, Technology and Higher Education in Student Creativity Program (PKM) 2018.

Described by Eduardus Oldi Kristianto, as the head of PKM-KC Team, the team made this innovation because it saw the problems that occurred in Indonesia. As a maritime country with 70% of its territory in the form of seas, of course, most of the Indonesian population work as fishermen.

Meanwhile, the main component of fishermen in fishingare boats or ships. They usually use a propulsion engine with fossil fuel generating engines, such as gasoline and diesel. Thus, the consumption of fossil fuels is increasing. While the fuel is also used almost for anything, including as a power generation energy.

Kristianto presented data from the Agency for Assessment and Application of Technology (BPPT 2014), where gasoline use reached 50% and diesel oil by 37%, making gasoline and diesel the most dominant energy used by Indonesians.

“If this goes on, it is not impossible that the fossil energy reserves in Indonesia will run out. In addition, the use of fossil fuels, in this case diesel and gasoline, can produce harmful exhaust emissions and are less environmentally friendly, “said Kristianto.

This emission gas if accumulated in large quantities can also disrupt the marine ecosystem, including the fish.

“From the problems we try to develop a tool called Pro-Gensine (Propulsor and Generator Ship Engine), the engine as well as a power plant in fishing vessels,” he said.

The so-called eco-anemo magneticbased engine technology is utilizing wind and magnetic power to generate a source of electrical energy, as well as a ship’s engine drive.

Pro-Gensine working principle that is utilizing electric motion force generated from the movement of magnets with wind-assisted wire windings which then generate electrical energy.

Thus, the innovation of the PKM-KC Kristianto Dkk Team lies in the energy source used and the design of a tool that allows to generate propulsion energy and engine power for bigger fishing vessels.

In addition, Pro-Gensine does not use fossil fuels, so it can improve the working efficiency of ship engines and reduce the costs spent by fishermen because the making of tools and maintenance is relatively cheap.

With the working principle of the engine and fuel used, this Pro-Gensine tool can help maintain the sustainability of the Indonesian environment to be healthier, as it reduces the use of fossil energy (diesel and gasoline). So as to save costs and increase the income of fishermen as well as the Indonesian economy. (*)
