At the Stasiun Mebel Jepara store, there are problems regarding recording the results of transaction services, where the shop owner calculates the transaction results relying on a calculator and does not use a computer, product data collection also depends on recording on books so that employees have difficulty seeing product prices because they have to communicate again with the shop owner. Shop owners also find it challenging to record and collect data on products to be repaired and forged, so shop owners often seek back information obtained through private chats from customers. The author builds the Stasiun Mebel Jepara website using the Scrum method and the Laravel framework. The author uses the Scrum method because it is iterative, incremental, and can apply a continuous learning culture. The author decided to use Laravel because it has complete documentation and can be used freely and free of charge—the work on this final project resulted in the Stasiun Mebel Jepara Website. After building the Stasiun Mebel Jepara website, the author tested the website’s usability using the System Usability Scale. The results of testing on 169 respondents in using the System Usability Scale website showed that the average SUS score of respondents was 64.41 with an interpretation of the C grade category. Respondents assessed that the website created was OK (adjectives) and marginal (acceptability), and passive in terms of NPS.","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":"130305413","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}

Although there are many alternatives to mobile text communication such as Whatsapp or LINE based online, SMS is still very commonly used because it only requires mobile number information and mobile signals available. Because of the ease of disseminating information with this SMS media, many people use SMS to send unimportant or even harmful messages to mobile device users. This unimportant SMS is referred to as SPAM. The number of SPAM messages that enter a person’s mobile phone filled the inbox with non-essential information, covered important information, wasted user time, and hindered communication. Therefore, a system that can automatically classify SPAM is required. Data obtained from this classification system may contain sensitive user information such as mobile numbers. Therefore, a SPAM SMS classification storage system with a blockchain platform is created. In this work, we use Hyperledger Composer to create our blockchain. Blockchain technology is used because it is an immutable and secure data storage system that can maintain the confidentiality of sensitive information that may be contained in SPAM messages.","PeriodicalId":446396,"journal":{"name":"2021 17th International Conference on Quality in Research (QIR): International Symposium on Electrical and Computer Engineering","volume":"67 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":"128201812","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 renewable energies whose technology has recently been developing is wind power; however, it still suffers from a drawback due to the fluctuations in energy production. Increasing wind energy potential requires a wind power prediction method that can predict the intermittent patterns of the prediction result from the generated wind power. In dealing with the frequent intermittent patterns that fluctuate frequently and have many variations, the Triple Exponential Smoothing Multiplicative LSTM (TES-MLSTM) model can read them and then predict with a short term few steps ahead. In this paper, LSTM Bayesian Network as another deep learning method is proposed and compared with the TES-MLSTM. This method uses the same LSTM base, enhanced with its hyperparameter tuning and run in a Bayesian Network. The model parameters are learned from the training data, and hyperparameters are tuned to get the best fit. The tuned hyperparameter will be processed using Bayesian Network. In the experiment, we used the 2013 dataset of Pandansimo wind power plant (PLTB) in Indonesia as the input data. The average wind power prediction errors (MSE) using the TES-MLSTM and LSTM Bayesian Network are 0.891 and 0.644, respectively. It can be concluded that the proposed LSTM Bayesian Network method is more accurate in predicting the wind power potential of a wind turbine than the TES-MLSTM method.","PeriodicalId":446396,"journal":{"name":"2021 17th International Conference on Quality in Research (QIR): International Symposium on Electrical and Computer Engineering","volume":"56 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":"129966737","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 through the Indonesian National Aeronautics and Space Agency (LAPAN) has two micro satellites with the AIS mission, namely LAPAN-A2/LAPAN-ORARI and LAPAN-A3/LAPAN-IPB. LAPAN will also build another micro satellite that carries AIS in order to get near real-time data. AIS based satellite has problems with large VHF antenna dimensions and data collisions in high traffic areas. The final dimension of the purposed antenna is 133.00 x 88.00 x 1.52 mm3, therefore this antenna can be applied in micro satellite. The simulation results show that the antenna works at a frequency 160.93-164.04 MHz with gain 1.654 dB. Miniaturization with meander-line and metamaterial structure technique has succeeded in reducing dimensions by 42%. This antenna has an omnidirectional radiation pattern with a beamwidth of 88.26°, and when this VHF antenna is installed on a satellite, the projection of the antenna on the earth’s surface is reduced by 50% from existing antenna. Hence this antenna can be used to reduce data collision of the satellite.","PeriodicalId":446396,"journal":{"name":"2021 17th International Conference on Quality in Research (QIR): International Symposium on Electrical and Computer Engineering","volume":"25 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":"131681793","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 will cause various kinds of diseases. Therefore, food that is clean from bacteria is very important to maintain. Various solutions have been developed by researchers to provide a fast, sensitive, and cost-effective way to detect pathogens such as bacteria. The use of electrochemical biosensor devices is very commonly used to detect bacteria, viruses, fungi, and others. This approach is to identify infections quickly and accurately. In this study, the antenna biosensor was designed to detect bacteria. The antenna is designed to operate at a working frequency of 2.45 GHz (2.4 – 2.5 GHz) using a proximity coupled feed. The antenna is printed using Roger 3010 as a substrate material which has a thickness of 1.28 mm. Antenna biosensor testing was carried out using three (3) liquid samples, namely pure water (Aquadest), fresh milk, and Yakult. From the test results of the antenna without using a liquid sample, it was found that the antenna was able to work at an average frequency of 2.496 GHz with the best reflection coefficient at -16 dB. There is a shift in frequency compared to the frequency in the simulation. Tests using distilled water showed that there was no frequency shift, but testing with milk showed a decrease in frequency to an average frequency of 2.417 GHz. As for testing with Yakult, the frequency is on average at 2.491 GHz. As an initial hypothesis, the bacteria found in Yakult caused a slight shift in frequency from the original frequency. This is because fermentation in Yakult caused by bacteria results the viscosity to decrease compared to the viscosity of fresh milk.","PeriodicalId":446396,"journal":{"name":"2021 17th International Conference on Quality in Research (QIR): International Symposium on Electrical and Computer Engineering","volume":"2013 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":"127310532","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 prevent the spread of the virus in public places, a body temperature screening process using an infrared thermometer is required. The two sensors that are commonly used as infrared thermometers are the MLX90614 and AMG8833 because of their high temperature range and good accuracy. However, the measurement results can be affected by the measuring distance, room temperature, and physical activity in the human body. Therefore, an infrared thermometer with two sensors arranged in overlay was designed to evaluate the performance of infrared thermal sensors based on measuring distances (15, 30, 40, and 60 cm), 2 rooms (26.4 °C and 30 °C), and physical activity on the object. The results in the 30 °C room at 15 – 40 cm show measured temperature above 36 °C for both sensors, while in the 26.4 °C room it decreased up to 35.32 °C. At 15 cm in a 26.4 °C room, the measured temperature results are the closest to the reference values with a difference of less than 0.3 °C for the MLX90614 sensor, while at 60 cm, the results are the furthest from the reference values also it has larger difference value, which is 0.21 °C for the MLX90614 and 1.01 °C for the AMG8833. In conclusion, the MLX90614 sensor is better than the AMG8833 sensor because its outputs are closer to the reference values.","PeriodicalId":446396,"journal":{"name":"2021 17th International Conference on Quality in Research (QIR): International Symposium on Electrical and Computer Engineering","volume":"54 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":"132485922","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}
