Abstract

This research is motivated by the existing security system in motorcycles that still considered to be not secure enough due to the use of conventional keys, which are relatively easy to be bypassed. The purpose of this research is to design and implement a motorcycle security system using a fingerprint-based Arduino. The research was conducted at a motorcycle workshop located at Jln. Tandipau IV, Sakti Village, Bua Sub-district, and lasted for 3 months. Qualitative data was collected, consisting of text-based information and non-numeric data obtained through interviews and literature review. Based on the observations made by the researcher, the fingerprint system works effectively when the fingerprint is dry. It responds slowly or may not respond at all if the fingerprint is wet, oily, dusty, or injured. The response time for fingerprint recognition when placing a fingerprint on the sensor takes 1 to 2 seconds.

Abstract

This research aims to improve the user experience in learning English on the Hanna Hersop online course website by proposing the addition of a picture guessing game feature equipped with object detection. Hanna Hersop is an English Course and Training Institute (LKP), providing English language learning materials offline and online. The research results show that adding the image guessing game feature with object detection significantly improves the users' learning experience. The object detection function in the picture guessing game not only provides additional challenges in learning, but also provides a more interesting interactive experience. This picture guessing game utilizes M15.js as a JavaScript machine learning library which provides access to ML algorithms in the browser built on Tensorflow.js and JavaScript, CSS, HTML as a framework for designing picture guessing games on websites. The results of this research provide valuable insights for developers and organizers of online English courses, as well as contributing to further understanding of how digital technologies, in particular object detection, can be used effectively to improve the quality of learning. that way course participants can gain additional benefits in understanding and practicing English, creating an innovative and effective learning environment. The integration of object detection in the picture guessing game feature is an innovative solution in creating a more interesting and effective learning environment

Abstract

This research aims to determine student satisfaction with the SiKuli Muhammasiyah Riau University website, which is e-learning at Muhammadiyah Riau University. The population in this study were all students from the Faculty of Teacher Training and Education and the Management Study Program at Muhammadiyah University of Riau. The research sample consisted of 80 students in each study program who were taken using proportional random sampling. The data collection technique uses a questionnaire. Before the questionnaire is used to collect data, the questionnaire is tested for validity and reliability. Test the validity of the analysis instrument used by factor and item score analysis with a total score. The data analysis technique used is descriptive analysis with percentages. The results of research using the Chi Square and Webqual methods of measurement based on quality function deployment (QFD) are to measure the quality of a website based on research instruments that can be recommended into three variables, namely: usability, information quality, and interaction services. All of them are measurements of consumer or user satisfaction with the quality of the website.

Abstract

This research aims to design and build a web-based information system for data collection on members of the East Walenrang Toraja Church Sunday School. The research method used is the waterfall method. Data collection techniques used literature, interviews and observation. The design of a web-based information system for data collection on members of the East Walenrang Toraja Church Sunday School class was designed using the UML modeling language. The system was created using the PHP programming language, the Laravel Framework as data processing, HTML as the website display design and MySQL database as the data storage medium. The design of a web-based information system for data collection on members of the East Walenrang Toraja Church Sunday School was tested using Black Box testing to obtain an information system that worked well. Meanwhile, the results of usability testing are that this system is suitable for use.

Abstract

Forest areas have a function of storing carbon dioxide and producing oxygen from trees and plants. The function of forests is very important for life, so forests are highly protected. One solution that can be taken is to take preventive measures, namely monitoring fire hotspots in forest and land areas by air. This research was tested using the same dataset as the YOLO (You Only Look Once) algorithm against the You Only Learn One Representation (YOLOR) algorithm with a train data division model of 1188 image data and test data of 75 image data with mAP results of 66.36%. . So it can be confirmed that the YOLOR algorithm is better than the YOLO algorithm which gets an mAP value of 50.65%.

Abstract

SeaBank is a digital banking service launched by Sea Group, a technology company from Singapore. SeaBank provides various digital banking services, such as money transfer, bill payment, e-wallet top-up, and investment.In a nutshell, SeaBank is a digital banking service that offers convenience and ease of use for its users. The results of the study show that the Sea Bank application has strengths in the form of competitive interest rates, user-friendly and intuitive applications, free admin fees, good service and transaction security, and rapid revenue growth. However, the Sea Bank application also has weaknesses in the form of lower daily transaction limits than Jenius, the absence of credit card features, suboptimal customer service, less diverse promo and reward programs, and a lack of innovative breakthroughs in the services provided. On the other hand, the Sea Bank application has opportunities in the form of the potential to expand online or mobile banking services, economic growth, the large number of Shopee users, the target market of millennials, and the market trend towards digital banks. However, the Sea Bank application also faces threats in the form of government regulation changes, economic uncertainty, Jenius's complete features, the potential for cyber security vulnerabilities, and changes in consumer behavior trends in using banking services. Based on the results of the SWOT analysis, the most appropriate SI/IT strategy for the Sea Bank application is to implement attractive loyalty programs, improve data security and privacy, and optimize the use of technology.

Abstract

Many people are still confused about ordering the voltage level for electricity use in newly built homes, so that for households that previously needed a voltage of 900 VA, it was sufficient but used 1300 VA and vice versa, if the use of a large voltage of 900 VA is not in accordance with the number of customers' needs, then there will be a disturbance in the balance between the amount of voltage used and customer needs, but by applying the fuzzy method this can be predicted. The aim of this research is to predict the voltage of household electricity usage using the fuzzy Tsukamoto method. This method was chosen because it is flexible, and has tolerance for existing data and also has the advantages of being faster in computing, more intuitive, and also produces accurate prediction values. The results of implementing the fuzzy Tsukamoto method were tested for accuracy using the Mean Absolute Percentage Error (MAPE) method. The first test used 20 data as test data and the second test used 30 test data, so that the results obtained from the first test were 8.35% and the second test was 11.77%. Based on the table of capability values of the MAPE method forecasting model, the results of implementing the fuzzy Tsukamoto method can be used to predict the amount of household electricity usage with a percentage value < 20%, which is a good forecasting model capability.
