Abstract
The impressed current cathodic protection is one of the effort to prevent a metal from corrosion by supplying electricity to metal objects. However, the protection system that supplies electricity must always be monitored so that the electricity intake to the metal object is sufficient to protect it from the corrosion. The way how to monitor the electricity intake to the metal is to read the current in taking on the metal. To read the electric current more easily is to use an application software. This research talks about the application design to display the electric current in taking on the metal through the computer screen. In order to read the electric current directly, the Advantect Data Acquisition Modul (ADAM) devices are used. The results show that the application is able to display the value of protection current for iron plate steel with size 30x10 cm are between 0.15 A to 0.18 A while for iron plate with a size of 30x13 cm are between 0.20 to 0.24 A. These values also avoid the over protection.

Published: December 2019

AbstractThis study aims to examine the single pole detection algorithm using a confusion matrix model which is a specific table that makes it easy to visualize the performance of an algorithm. The algorithm tested is the YuRHoS pole detection algorithm, a new algorithm developed by researchers to detect pole objects with not poles. Methods used is by calculating three aspects of algorithm performance in machine learning, namely sensitivity, specificity, and accuracy. The value of the three aspects of performance depends on four variables, namely true positive, true negative, false positive and false negative. The calculation process is done by matching the pixel detection region with the ground-truth region. The test results for 4 (four) different single pole images found that the YuRHoS pole detection algorithm is better than other algorithms on two measurement aspects, namely specificity, and accuracy. Excellence aspects of specificity obtained because of its ability in detecting the object instead of a pole. Excellence aspects of accuracy indicated because more accurate in detecting a pole. As for sensitivity aspects, both the detection algorithms are having the same reliability in correctly predicting a pole.
