Abstract

Solar  energy  is  an  inexhaustible  source  of  renewable  energy.  Indonesia,  which  is  a  tropical country  that  is  crossed  by  the  equator,  has  a  fairly  high  solar  intensity  per  year.  With  this potential, it is necessary to process or develop the alternative energy. One way to develop this potential is to use solar panels that can convert solar energy into electrical energy. In this study, we developed a data logger system design tool for the installation of an Arduino-based 600 W inverter grid tie (GTI) solar panel. Nowadays, observation or monitoring still uses conventional or  manual  methods.  Therefore,  in  making  this  task  we  made  a  voltage,  current,  and  power monitoring tool on a solar panel that functions as a current, voltage and power sensor with the Arduino Mega microcontroller as an output data store which will be communicated via Android. The results of the data will be analyzed by calculating the break even point (BEP) to determine the feasibility of procuring On-Grid solar panel systems. From the BEP calculation results, the average energy supply from solar panels is 5% or every month solar panels can reduce costs by Rp.42,000. From these results it is known that the value of the BEP from the procurement of On-Grid solar panels can be achieved for 7 years and 4 months, only then it will be profitable.

Abstract

Bearing is an important component in supporting engine performance. However, according to a study  by  Svenska  Kullager  Fabriken  (SKF),  bearings  are  also  one  of  the  components  that  most often cause 40% of engine damage. Bearing damage occurs during installation which is still done manually, namely being hit which results in high friction on the wheel axles. To overcome this, a tool is made with the heating method to carry out bearing installation which utilizes expansion of the  bearing.  Induction  heating  device,  is  a  solution  for  heating  bearings  which  has  not  been produced in Indonesia. Therefore, an induction heating system was created for heating bearings using the NodeMCU ESP8266 microcontroller as a controller and using a type k thermocouple temperature sensor as a temperature detector with the PID method. The use of this PID method as a  heating  temperature  control  when  it  reaches  the  desired  set  point,  the  heating  process  will automatically stop. The objects used are bearings with inner rings of 15mm, 17mm and 20mm. By making this induction heater, the performance of the tool is obtained with an average heating time to reach a set point temperature of 100OC is 3.64 minutes.
