Abstract

Elektrostimulator combined in acupunture therapy to provide the stimulation of electric energy at the point of the meridians of the body. Granting the power to create a balance of energy (chi) in the body. In administering the energy must pay attention to the voltage waveform, intensity, frequency and timing of stimuli. The purpose of this research is to change the system tools from analog into digital by changing the settings of the timer and frequency using the keypad that is controlled using the Microcontroller ATMega16. Specifications of the simulation tool elektrostimulator acupunture designed include the frequency setting of 5-100Hz, setting the intensity of a voltage 0 timer setting until 25Vac 60 minutes and has a spike waveform mode continou and electrodes used floating types. The test result show that simulated acupunture elektrostimulator tool result obtained in accordance with the compliance with the specifications but there is little the percentage error of frequency deviation i.e. 0.47% deviation of the timer of 0.29%, intensity of the voltage deviation of 0.073 % and waveform was nearing the same against his theory.

Abstract

Indonesia receives solar energy whose average daily energy radiation per unit area per unit time is about 4.8 kilowatts / m2. Solar energy is one of the most abundant, pollution-free, and optimally explored renewable energy sources. Indonesia located in the tropics is very suitable and has the potential to develop solar energy. In the utilization of solar energy, it is necessary to develop a technology capable of converting solar energy into the desired energy of electrical energy. The supply of electric energy during the day can still be controlled by solar cell, while at night controlled by Aki.This technology is known as solar cells or internationally known as solar cell or photovoltaic.Induction heating is the onset of heat on the metal exposed to the induction of the magnetic field, this is because the metal arising Eddy current or navel currents in a circular direction surrounding the magnetic field occurrence of the navel due to the magnetic induction that cause magnetic flux that penetrates the metal, causing heat metal.Designing Induction Heating Tool is a combination of solar cell technology with induction heating which benefits to the processing of tea production. This tool is able to induce the specimen so that the specimen becomes hot until it reaches the dry point reaches 100ºC. Power required to supply 300 Watt heater.
