Bearings are often found in automotive equipment and home appliances, one of them is the bearing that has found in a single-phase induction motor (water pump). But, until now the largest percentage of induction motor faults occurs in bearings. Therefore, an accurate system of bearing faults detection is the key to protecting an induction motor from such any faults. In this study, we proposed bearing faults detection on a single-phase induction motor with water loads and based on Internet of Things (IoT). This system used multi-sensors, i.e. a temperature sensor, a current sensor, and a vibration sensor. Some processes in this bearing faults detection system are feature extraction process using Empirical Mode Decomposition (EMD) and pattern recognition process using Backpropagation Neural Network (BNN). Then the results from pattern recognition is displayed through the Internet of Things (IoT) system. The results of this project show that EMD can decompose the vibration signal and BNN is able to classify signals with 100% accuracy of current signals and 98% for vibration signals.","PeriodicalId":446396,"journal":{"name":"2021 17th International Conference on Quality in Research (QIR): International Symposium on Electrical and Computer Engineering","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117023160","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}

Indonesia has just launched the first 5G network on May 21, 2021, as a tangible manifestation of the leading digital telecommunication. The 5G band allocation used for the first deployment is in the medium frequency band (2-6 GHz). In this paper, the 5G high-frequency band (beyond 6 GHz) is used to design a MIMO antenna for future deployment. The MIMO antenna is designed for 5G applications working at a frequency of 38 GHz. This allocated frequency was also recommended by the Federal Communications Commission (FCC). The antenna was designed by using a patch in the form of an octagon ring with microstrip line feeding. MIMO technique is used to increase system capacity with a gain value above 10 dBi. Antenna MIMO is designed using a material substrate RT Duroid 5880 with $varepsilon r$ = 2.2, thickness (h) = 0.254 mm, and tan $delta = 0.0009$. From the simulation, the S11 reached -29.5 dB, a gain of 13.44 dBi, mutual coupling below -20 dB, and bandwidth of 14.002 GHz (31.008 GHz to 45.01 GHz).","PeriodicalId":446396,"journal":{"name":"2021 17th International Conference on Quality in Research (QIR): International Symposium on Electrical and Computer Engineering","volume":"184 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123095317","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}

Physiognomy itself is a method of predicting a person’s characteristics based on their facial features. Each facial feature has its uniqueness and characteristics, such as variations in distance, overall shape, and size. The facial image as input data is processed in every system step. Finally, the system displays the personality of that person. Simulations show that each algorithm can perform its respective functions well. The simulation results show that the combination of extracting facial features using the Active Appearance Model and Convolutional Neural Network for solving classification problems produces a very good number of personality traits predictions with each model accuracy value between 0.8 to 1, or 0.8797 on average. In addition, the model made proved to produce a good performance for the classification process with a true positive rate between 0.8834 to 1, or 0.9417 on average. This method can also detect many personality traits, with 28 personality traits that can be detected.","PeriodicalId":446396,"journal":{"name":"2021 17th International Conference on Quality in Research (QIR): International Symposium on Electrical and Computer Engineering","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130103699","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}

One of the layers used in perovskite-based solar cells is the counter electrode. Activated carbon is one type of carbon that has the potential to replace metal as an electrode material due to its good chemical stability, high electrical conductivity, low cost, and abundance. Apart from that, CuSCN is a famous hole transport material because of its wide bandgap, good stability, and high hole mobility. Many studies have tried to combine the electrode material with hole transfer material in an effort to improve the device performance. This paper presents an investigation of the perovskite solar cell device performance with CuSCN-incorporated carbon electrodes. Concentration variations of CuSCN in carbon electrodes were carried out with values of 0.5%, 1%, and 2%. Different levels of CuSCN concentration in carbon electrodes resulted in different properties and performance of the device. Adding CuSCN with a concentration of 1% in carbon electrode yielded the best device performance with an efficiency of 0.0035%, fill factor of 0.32, $mathrm{I}_{mathrm{s}mathrm{c}}$ of 0.11 mA, and $mathrm{V}_{mathrm{o}mathrm{c}}$ of 0.14 V. Correctly combining the carbon material with hole transport material served a better the energy level alignment and hole transport properties.","PeriodicalId":446396,"journal":{"name":"2021 17th International Conference on Quality in Research (QIR): International Symposium on Electrical and Computer Engineering","volume":"211 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122878225","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}
