Energy’s consumption in Indonesia continously rises due to population growth, economic growth and life style of people. The limitation of supply fossil material in the future, encorages the use of friendly environment energy resources or use renewable energy sources such as (water energy, solar, wind, geothermal, biomass). However, in the most cases, utilization of energy resources are depend on the condition of the nature, it is therefore, an idea rises to develop a power plant that is not influenced by nature. Hence a prototype of earth’s gravitational power plant is developed in this thesis . The method used to design a prototype of Earth's gravitational power plant that by adjusting the balance conditions of the object, that can make rotation of the shaft and mechanical power to spin a generator. However, in designing a prototype of Earth's gravitational power plant, still use of external assistance source in the form of a 12V DC source to rotate the DC motor. To operate the system control the balance condition of objects so that make the system can continously spin. In this thesis a prototype of Earth's gravitational power plant developed it has dimensions of (length 64 cm, width 37 cm, height 82 cm) and the max power that can be produced is 1 kWh. In the maximum rotation of generator at 105.48 rpm, has been able to produce maximum voltage of 19.87 V and maximum current of 14 mA. the power plant need energy input of 0.43 kWh, here the electrical energy generated is greater than energy used to rotate the motor so that the system results an amount of free electrical energy of 1kWh - 0.43 kWh = 0.57 kWh. The maximum efisiensi of the system is 12%
