The multilayer technique was presented as an alternative to reduce the area of those elements. Furthermore, variation of lumped elements is still limited for multilayer CPW MMIC applications. Therefore, in this research, several variations of multilayer capacitors, inductors, and resistors for MMIC application were presented. The folded design of the capacitor and overlap design of the inductor was utilized to obtain higher capacitance and inductance, respectively. The NiCr resistor with various sizes was also designed to obtain various resistance values. The characteristic of the capacitor, inductor, and resistor was analyzed using scattering parameters and validated using measured data. The MIM capacitor with capacitances of 0.4 to 2.4 pF has been realized, spiral inductors with inductances of 0.6 to 7.6 nH, and NiCr thin film resistors with resistances of 20 $Omega$ to 150 $Omega$ were also presented in this paper.","PeriodicalId":406626,"journal":{"name":"2022 6th International Conference on Electrical, Telecommunication and Computer Engineering (ELTICOM)","volume":"201 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126071734","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}

The control of induction motor is usually done using an ac drive. In this paper, we will analyze the induction motor, that its terminal supplied by variable voltage variable frequency sources that using frequency voltage drive method (fvd method). The loads of the induction motor are digester, conveyor and pump. The result shows that the rotation of motor decrease from 2605 rpm to 2410 rpm with the increasing of the mass added to the digester reservoir from 1264 kg to 1670 kg.

Therefore, we need a mobile-based application that can identify the infectious skin disease herpes. An expert system is one of the fields of science that can solve a problem in a system. The expert system has several methods that can be used, namely case-based reasoning (CBR) and rule-based reasoning (RBR) methods. CBR can be used to solve a new problem by utilizing previous problems and RBR is a method that can be used to solve a problem using a rule base, where each rule is obtained from experts and literature studies. By applying the combination method of CBR and RBR which can be used to diagnose herpes skin disease, it is hoped that it will prevent the spread of herpes disease from spreading.","PeriodicalId":406626,"journal":{"name":"2022 6th International Conference on Electrical, Telecommunication and Computer Engineering (ELTICOM)","volume":"57 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113964152","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}

Every day there is rubbish that is not thrown in the trash, those that have been thrown in its place but are still wrong in distinguishing the type of garbage. In general, one of the types of waste is based on its nature, some are easy to decompose (organic), and some are difficult to decompose (inorganic). This research introduces five organic and inorganic waste objects by seeing whether the system can read objects at every position in the background and the number of objects in 1 picture frame. This system uses Tensorflow with a sample of 100 images for each object. Each sample object is given an identifier according to the object’s name and type. The sample is given an identifier for the system to learn to recognize the patterns and shapes of objects from the data objects we take. The results showed that the average percentage of system accuracy in detecting objects reached 90%, with the highest data accuracy reaching 99% tested on the banana peel, leaves, grass, cardboard, styrofoam, broken glass, bottles, cans, and nails. Furthermore, the authors try to put two or more different objects in the same frame and produce an average percentage value of 90%, as well as testing two or more similar objects in one frame simultaneously and producing an average value of 90%. From the test results, grass and bottle objects are samples that do not have read errors in the system design. For testing two or more objects in one frame, the author puts two similar objects and objects of different types. The result is that the system can recognize objects in the frame.","PeriodicalId":406626,"journal":{"name":"2022 6th International Conference on Electrical, Telecommunication and Computer Engineering (ELTICOM)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134050563","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}

This research conducted the effect of changes in load and excitation capacitance on the voltage and frequency of the generator. From the results of this study, the load change is inversely proportional to the voltage and directly proportional to the frequency. Suppose the value of the excitation capacitor used is smaller than the specified value. In that case, the resulting voltage will be smaller, where the value of the excitation capacitor is inversely proportional to the generator frequency.","PeriodicalId":406626,"journal":{"name":"2022 6th International Conference on Electrical, Telecommunication and Computer Engineering (ELTICOM)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128813080","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}

Stress, at some level, can harm human health since it can cause various diseases that humans often underestimate. These diseases include headaches, cramps, heart attacks, high blood pressure, and even strokes can occur. Stress levels are detected by manually filling out questionnaires or conducting self-assessment tests. However, it seems subjective because the results depend on honesty in answering the questionnaire. Therefore, in this study, we conduct a study to classify human stress levels by observing brain wave activity using an Electroencephalogram (EEG). Since EEG signals can directly reflect the brain’s electrical activity, they can be used as an objective measure for classifying stress levels. In this study, the method used in classification is K-Nearest Neighbour. The signal processing stages include pre-processing, feature extraction using Independent Component Analysis (ICA), and then classification using K-Nearest Neighbour. This research used 62 data as training and testing data. After testing the system, it was concluded that the K-Nearest Neighbour method could classify stress into normal and high levels with an accuracy of 75% with a k-value of 7.","PeriodicalId":406626,"journal":{"name":"2022 6th International Conference on Electrical, Telecommunication and Computer Engineering (ELTICOM)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127975618","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}

To obtain the estimation model used quadratic parabolic regression method and the addition of the coefficient of Root Mean Square Error (RMSE). Based on the results of the quadratic parabolic regression method and the results of the RMSE values for each propagation model, a propagation model that is close to the research results is obtained, namely the Walfisch-Bertoni propagation model. By adding the RMSE coefficient to the Walfisch-Bertoni equation, an adjusted Walfisch-Bertoni model is obtained with a decreasing value of up to 25 dB for all routes. This shows that the appropriate propagation model for the University of Sumatera Utara is the Walfisch-Bertoni propagation model.","PeriodicalId":406626,"journal":{"name":"2022 6th International Conference on Electrical, Telecommunication and Computer Engineering (ELTICOM)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131324684","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}
