Abstract
The design of micro power plants from high-power engine noise has been carried out. This study aims to compare the output voltage generated between the ITK^s generator set (genset) noise engine source with the generator function and determine the number and variations of the piezoelectric circuit that can produce an output voltage greater than the engine generator ITK^s genset. The energy harvester of noise consists of 1 1/4 λ- resonator box, 3 fins, and 3 ceramics piezoelectric. The noise source
Using to media, function generator and ITK^S genset. The test is carried out by maintaining the average noise intensity of the SPL (sound pressure level) function of the generator and engine generator set ITK at 103.5 dB. The number of piezoelectric circuits consists of 1 piezoelectric, 2 piezoelectric series, 2 parallel piezoelectric, 3 piezoelectric series, 3 parallel piezoelectric, and 3 parallel-series piezoelectric. In this test, noise intensity data, and piezoelectric output voltage are taken for 3 minutes and repeat 5 times for each variation. The experimental results show the average output voltage value generated from piezoelectric with generator engine noise source is greater than the stable function generator noise source when the circuit variation is 1 piezoelectric, 2 parallel piezoelectric, 3 parallel piezoelectric, and 3 parallel-series piezoelectric. With a source of engine noise generator series 3 piezoelectric series produces an average output voltage that is greater than other circuit variations with a value of 201.07 mV SPL an average of 103.5 dB and an average frequency of 223.62 Hz. Increasing the number of piezoelectric when arranged in series will produce a greater voltage.
