Fuzzy Logic Implementation on Battery Pole Terminal's Height Checker Machine Using Moving Head Laser Sensor

The process of checking battery pole terminal heights using a Pole Height Checker (PHC) machine often results in non-compliance with quality standards, resulting in the machine being decommissioned for four to five years. Based on observations, there are several factors, one of which is the accuracy of the sensor which coincides with mechanical friction so that many misjudgments occur. This update changes the method of reading the pole, which initially used a mechanical sensor touching the pole, to a laser sensor movement that does not touch the pole. Therefore, in this research, an updated battery pole terminal height measuring system was built using a moving head laser sensor. Apart from that, it can also increase the accuracy of sensor readings on battery pole terminals. The basic point of using fuzzy logic is to be able to classify the pole height range according to quality standards, namely 17-20mm. From the test results, the sensor readings and actual caliper readings have been properly verified and judgments are made according to actual conditions. By comparative testing, the previous system has an error rate of 6.1% and the new system has an error rate of 1.3%, battery pole terminals can be measured according to quality standards and there are no reading errors due to inaccurate sensors.
