This course is a skills course in Mechanical Engineering. This course studies a range of ways to convert one form of energy that exists in the world into another form that is more beneficial for human life. In this case, basic courses such as: heat transfer, fluid mechanics, thermodynamics and mathematics are needed as support so that this energy conversion material can be mastered well. Solar energy, wind energy, water energy, geothermal energy, ocean energy (waves, ocean currents, sea waves, etc.) can be converted into energy that humans really need, for example electricity, heat, etc.
