Problems arise when schools have to use e-learning for students and online assessments have to be done. It is known that difficulties are experienced when taking semester exams or when teachers give assignments online. This study applies text mining techniques using the Ratcliff/ Obershelp algorithm to determine the similarity value between two strings, namely between student answers and the teacher's answer key. A collection of answer data obtained from one of the 6th grade teachers at elementary school and applied to the Examz web application. This application is built to find out the status of answers based on the error tolerance that has been predetermined by the teacher. The results of this study indicate that the Ratcliff/ Obershelp algorithm has achieved a correction accuracy rate of 90% in Natural Science subjects, 93% in social science, 83% in Civil Education, 91% in SBK, and 97 in Religion. The final result for the average accuracy of the application is 91.00% in determining the status of student answers.","PeriodicalId":178443,"journal":{"name":"2021 4th International Conference of Computer and Informatics Engineering (IC2IE)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125451801","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}

Emotions recognition can use neuropsychology signals obtained through the Electroencephalogram (EEG) device. EEG recording has a multi-channel that is taken from some area in the brain. Each channel provides information from a specific part of the brain, so the signals need to be processed in parallel. The multi-channel recording enriches emotional information so that the signal recognition of each channel is combined with the fusion function. In this way, multi-channel processing does not interfere with the signal sequencing within each channel. Convolutional Neural Networks (CNN) is one of the methods that can learn and recognize patterns in one area, such as the eye. This paper proposed multiple CNN to recognize emotion. First, the EEG is filtered using a wavelet to get a frequency component of 4-45 Hz that represents the characteristics of negative, neutral, or positive emotions. The frequency band contains Theta, Alpha, Beta, and Gamma waves. The experiment gave that Multiple CNN increased accuracy from 64.14% to 80.66% compared to Single CNN. In addition, a wavelet filter to maintain the signal sequence can obtain slightly better accuracy results than wavelet extraction.","PeriodicalId":178443,"journal":{"name":"2021 4th International Conference of Computer and Informatics Engineering (IC2IE)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121830648","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}

Knowledge has an essential role in improving the achievement of the company. By managing knowledge properly, it can increase the achievement of the company. This research is motivated by differences in the achievement of KPI targets between branches which are much different. Less than 30% of branch offices can achieve the target, resulting in unfulfilled achievements. Implementation of knowledge management is one way to improve company achievement, but 50-70% of companies fail in implementing knowledge management because it is only based on theory without considering organizational conditions and readiness. Measurement of implementation readiness is expected to reduce the risk of failure. The purpose of this study is to measure the readiness for the implementation of a knowledge management system. The method used in this study is a mixed-method, namely qualitative and quantitative research. The researcher builds the factors from a systematic literature review by mapping the critical factors of the implementation of knowledge management obtained 21 factors. Business experts validate and add three factors to accumulate as many as 24 factors, then weighted using AHP to organizational experts, and the results are multiplied by the instrument to calculate the level of KM readiness. The results of this study are the level of KM readiness at PT XYZ with a value of 84% or at the stage of being ready to apply knowledge management. Still, factors with values below 75% need to be better prepared, namely informal factors, training, technical knowledge, and responsibility.","PeriodicalId":178443,"journal":{"name":"2021 4th International Conference of Computer and Informatics Engineering (IC2IE)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127833918","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 main things that must be done in developing this system is to do usability testing. In this study, a test will be conducted on the toddler equipment donation application by combining the SUS method to measure usability and the Net Promoter Score (NPS) method to measure user satisfaction and user willingness to recommend the system to others. This study involved 30 respondents who were divided into two groups, namely posyandu (Integrated Healthcare Center) as admins and the second is donors. Sampling selection using non-random sampling. The SUS method is reliable for measuring system scope from small to large. This is because there is no relationship between sample size and reliability. Where by using the SUS method have a score of 71.57. It is classified as a good product and the results of using NPS get a value of 49% which means excellent NPS.

The data stored on the smart card will be changed when the data exchange is carried out, so that data with different contents will be received by the recipient. Cryptography is a solution that can be used to secure data on a smart card so that its contents cannot be changed. Acorn's algorithm is an algorithm that can guarantee its security aspects in terms of confidentiality and authentication. Snow's algorithm is an algorithm that is designed to be implemented on hardware. Acorn's Algorithm and Snow's Algorithm can be implemented on resource-limited devices such as smart cards because both algorithms are lightweight. The encrypted data on the smart card is the user ID and user balance, the data will be converted into ciphertext so that it cannot be read or changed by unauthorized parties. Test vector testing, and encryption and decryption performance testing are carried out to ensure the system can run properly.

However, it is rare to analyze the quality of school websites, where prior research has focused more on analyzing e-government and university academic websites. In order to remain optimal and maintain its quality, a school website also needs to be evaluated regularly. In general, recommendations for quality improvement of the website will be determined in this report. To understand the existing system as the basis for collecting data and information, UML artifacts are used, i.e., requirement statements, use case diagrams, and class diagrams. The approaches utilized in this study, i.e., ISO/IEC 25010:2011 as a universal quality measurement standard and Importance Performance Analysis (IPA), to determine each item's priority for website improvement to improve quality. According to the analyzed data, the current website's performance score average is 3.29, with a negative gap (−0.22). Additionally, the existing website also has issues indicated by items in quadrant I, i.e., US2, US8, FS3, PE2, IQ2, IQ3, and IQ4. These items are the main priority for website improvement. Through these improvements, website performance has increased by 0.41, which means the average improved website performance is 3.70 with a positive gap (0.19). These results indicate that users are satisfied with the improved website performance.","PeriodicalId":178443,"journal":{"name":"2021 4th International Conference of Computer and Informatics Engineering (IC2IE)","volume":"184 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134207791","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}
