Introduction An energy source is something around us that is capable of producing energy both small and large. Energy sources can be broadly divided into 2, namely renewable and non-renewable energy sources . Energy demand in Indonesia is growing with the rapid increase in development in the fields of technology, industry and information. With the increase in energy consumption in Indonesia and the decreasing reserves of fossil energy. Indonesia is ready to develop non-renewable energy. Various new Advance Sustainable Science. Engineering and Technology forms of energy have developed, including wind power, steam power, biomass, and so on . Today there is a shortage of energy sources and at the same time the load of modern electricity and devices based primarily and directly on electric power is increasing. This reality is a major challenge facing the government. Using multiple sources of energy instead of relying on a single source, especially if this source is a conventional source, is a necessary step. Conventional energy sources such as fuel and natural gas will end with time, so researchers are trying hard to develop and explore renewable energy sources such as the sun . , wind . , vibration . , and thermal energy . Most of the energy used is inaccessible energy so that accessible energy and / or other alternative energy sources are needed. Noise is noise pollution that generally occurs in dense residential areas, industrial areas, and others. Hence, that is wasted energy. Psychological and health effects caused by the smell of deafness, feeling depressed, hypertension, and others. To prevent this, workers who are in areas with a high level of protection are required to be obliged. Sound or oil is one of the most widely available sources of energy. Sound in fact is a mechanical wave generated from pressure oscillations through several media. Sounds that can be heard by the human sense of hearing with a frequency from about 20 Hz to 20,000 Hz are called audiosonics. In air at standard temperature and pressure, sound wavelengths range from 17 m to 17 mm. Sound energy is the energy produced by sound vibrations as it travels through air, air, or other space. The frequency of the first sound energy source is infrasonic. Infrasonic is a very weak sound because the vibrations produced in infrasonic waves are less than 20 vibrations per second. Audiosonics is a type of sound that can be heard by humans. Ultrasonic waves are waves with sound vibrations of more than 20,000 vibrations per second . Noise is noise pollution. Therefore, noise pollution needs to be minimized or used for energy sources. In this research, noise pollution is stated by a sound signal that is predicted to have the potential to be converted into energy. Methods Development Model This research was conducted by means of experiment. This research was conducted to investigate the potential for mechanical vibrations for a source of electrical energy. The stress of this research can be obtained from the measurement of the oscilloscope which comes from mechanical vibrations. The current is obtained by adding a load in the form of a resistor. Then the power is obtained from the multiplication of voltage and current. Research Procedures The research procedure in this thesis is as follows: Piezoelectric Sensor Testing. Firstly, the sensor is installed and the vibration is set at 0. 5 m/s2 by adjusting the volume. Later on, the output . sensors 1, 2, 3 and 4 were measured. It is measured After that the voltage multiplier module is installed and measured the voltage. The module consists of 4 circuits. The circuits which represent the multiplier voltage are connected to the piezoelectric sensors in series mode. The multiplier voltage is arranged from 2 Capasitors and 2 Diodes.

In order to recharge the battery having voltage 1. 2 volt, the measurement of the intensity of the loudspeaker was verified. According to table 1, it was found that at 2 ycoAEyc2 of vibration is best because the value is 1. 4 V nearest to 1. 2 V, which is the voltage of the rechargeable battery.
