In Indonesia, there is a company that is in charge and responsible for processing and distributing electricity to the public, namely PLN or more specifically the Substation. To distribute electricity at this substation, there are primary equipment that functions as a transmission regulator, one of which is a power breaker (PMT). PMT is one of the important assets in the reliability of the electricity system at the substation, so periodic testing and maintenance is very necessary. Testing and maintenance on PMT are very diverse from insulation resistance testing, simultaneous testing (Breaker Analyzer), SF6 gas characteristic testing, and PMT contact resistance testing. This contact resistance test is carried out to determine the resistance value of the PMT contact, from the resistance value obtained it can also be seen for the value of the power loss generated by the PMT when operating.","PeriodicalId":320287,"journal":{"name":"JEEE-U (Journal of Electrical and Electronic Engineering-UMSIDA)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127405631","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In its use, bearing damage is one of the biggest types of damage that is often found in induction motors. Bearing damage can lead to increased vibration, increased noise, increased working temperature, and decreased efficiency. Efficiency reduction can be used as information on the condition of the motor so that this information can be used to detect damage before more serious damage occurs. This research discusses the stator current analysis method and the efficiency of damage to the motor through two harmonic amplitude ratios equipped with the fast Fourier transform (FFT) algorithm in detecting damage to the outer race bearing. It is hoped that this efficiency can be used as an evaluation of the extent to which motor energy waste occurs before more severe damage. The efficiency results on the damage to the outer race bearing using the FFT method get the highest efficiency value of 1.47 and the lowest value of 0.66.","PeriodicalId":320287,"journal":{"name":"JEEE-U (Journal of Electrical and Electronic Engineering-UMSIDA)","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117140456","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the grouping, some bacteria are pathogenic. With a microscopic size, many pathogenic bacteria are found around and spread through the food eaten or by touching objects around them, then cause diseases such as diarrhea, vomiting, and others. As a more effective effort to help the government and society prevent disease caused by pathogenic bacteria, a system for the identification and classification of pathogenic bacteria K-Nearest Neighbor was created. This system uses a biological microscope that is attached to a webcam camera above the ocular lens as a tool to see bacterial objects and assist in bacterial capture. Rough player rotates automatically (auto-focus) in image capture. In the process of classification and identifying bacteria, the K-Nearest Neighbor method is used, which is a method with the calculation of the nearest neighbor or calculation based on the level of similarity to the dataset.

The test was between implementation of overhauls on schedule and eliminating minor overhauls when the status was good. The results of data processing obtained that the best decision is not to do minor overhaul elimination because of the potential to reduce 29.77% good conditions, 30.69% improvement in moderate conditions.

Digital image processing is a scientific discipline that studies image processing techniques. The use of image management is increasing and is used in various fields, one of them in the field of robotics can be applied as an object detector. Image management is chosen in terms of detection because it is able to recognize objects and colors quickly. In the field of robotics these advantages are used to control robots to navigate, one example is in soccer robots. Soccer robots must be able to detect the presence of the ball to find and carry the ball and kick it towards the goal. The ball in the match system has been determined with a definite color, in this case it is orange. Therefore, the robot must be able to detect the orange ball to detect it. In detecting the ball, the parameters produced in this system are the distance of the robot to the ball, the angle of direction of the ball and also the ball according to the color or not. To solve this problem in this study using a method that is processing the RGB image produced by the camera into HSV after which color filtering is done and then finished using the find contour method. The results of this study noted the accuracy of the system in tracking ball objects by 92.87 percent at the distance of the ball to the camera and 88.19 percent at the angle of direction of the ball to the ball. The level of accuracy is due to the position of the camera when shooting.","PeriodicalId":320287,"journal":{"name":"JEEE-U (Journal of Electrical and Electronic Engineering-UMSIDA)","volume":"89 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132769116","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
