Abstract

Information security is vital in today's digital era. Micro small medium enterprises are always required to survive with the unfavorable conditions. Through e-commerce, businesses can be helped to sell their products widely. Carelessness in managing information in e-commerce applications by business owners can cause great losses. In this article, the information security awareness of MSMEs will be analyzed using the Knowledge Attitude Behaviour method developed by Kruger-Kearney. The sample of respondents was taken using a purposive sampling technique where the criteria for respondents were categorized micro small medium enterprises owners and using e- commerce applications to sell their products. This article succeeded in analyzing, that the awareness of business owners was in a good category. The resulting score is 93 and is considered a high value. There are several factors that cause the high awareness score obtained, one of which is the training held by the state-owned creative house. This article can be developed for further research.

Abstract

 The rapid development of information technology and communication has facilitated various aspects of life, including the banking sector. Jenius is one of the digital banking applications that has been downloaded by five million users and continues to grow. With the increasing number of users, there is a growing number of opinions written about their experiences using the application, making it difficult to identify reviews through manual monitoring without textual data processing. This study aims to classify user reviews of the Jenius application on Google Playstore using the Naive Bayes algorithm and Particle Swarm Optimization feature selection. The data used consists of 3047 user reviews of the Jenius application collected from January 16, 2022 to April 13, 2023 and will be divided into two classes, namely positive and negative sentiment. This study also compares the Naive Bayes algorithm using PSO feature selection and without using PSO feature selection. The test results of the two methods indicate that the PSO feature selection with 800 iterations proves to be effective in optimizing the performance of the Naive Bayes algorithm model with an accuracy of 98.50%, precision of 97.81%, recall of 99.36%, and F1-score of 98.58%. Meanwhile, the performance level of the Naive Bayes algorithm without using PSO feature selection is lower with an accuracy of 96.68%, precision of 94.83%, recall of 99.04%, and F1-score of 96.88%.

Abstract

This study aims to evaluate the usability level of Aruna Heroes developed by PT Aruna Jaya Nuswantara. Usability is a crucial factor in assessing the success of a product in meeting user needs. Using the Heuristic Evaluation method based on the System Usability Scale, this research identifies usability issues and barriers in Aruna Heroes and provides recommendations for improvement. The research methodology used is a mixed-methods approach with a sequential explanatory design. The study combines quantitative data through the use of the SUS and qualitative data through descriptive variable analysis and interviews with Aruna Heroes users. The analysis is conducted by applying heuristic evaluation principles to the Aruna Heroes and measuring the usability level using the SUS. The research findings indicate that Aruna Heroes has achieved a good level of usability and successfully meets 9 out of 10 indicators from the Heuristic Evaluation variables. However, in the context of usability and heuristic evaluation, Aruna Heroes still has room for improvement, particularly in the areas of Help Users Recognize, Diagnose, and Recover From Errors, Error Prevention, and Help and Documentation.

Abstract

Cardiovascular health and blood oxygen levels are critical indicators for monitoring a person's physical condition, especially during activities or exercise. Monitoring these two parameters is essential to ensure that an individual remains within safe limits to continue physical exertion. Therefore, a portable device capable of accurately and in real-time measuring blood oxygen saturation (SpO₂) and heart rate (BPM) is required. This study aims to design and develop a pulse oximeter device based on the Arduino Uno microcontroller using the MAX30102 sensor, equipped with LED indicator lights and a keypad as a user input interface. Users can input their age through the keypad, and the system calculates their maximum BPM as a safe threshold for physical activity. The LED lights serve as visual indicators to signal whether the user's SpO₂ and BPM values are within the normal range. Testing results show that the device is capable of measuring blood oxygen saturation with an accuracy of 99.97% and heart rate with an accuracy of 98%. With its compact size, this device has the potential to be used practically in various situations, both by individuals and healthcare personnel for preliminary health monitoring.

Abstract

Internet use is currently growing rapidly in many aspects of life; education, economy, social life, politics and culture. The needs and rapid developments in the use of the Internet network require a balance provision of Internet connection. In fact, connectivity is not always run smoothly because of low bandwidth capacity and network traffic increases. These problems cause network connection interrupted and data lose. Load balancing system is one of the solutions to get a better quality of internet service. Using more than one different ISP (Internet Service Provider) which is then balanced with load balancing system, can make the traffic run optimally, maximize throughput, minimize response time and avoid overload on any of the connection lines. This system worked by distributing the traffic load on two or more connection lines in a balanced way so that traffic can run optimally. By using load balancing system, when the internet is interrupted, then there will be a backup. This study focuses on implementing backups from Internet network sources or backups from dependency on one Internet service provider. The method used in this study is a case study. The instrument used is an observation at the Benteng Village Office in Ciamis. The process started by selecting the right ISP source to be used as a backup. Then continued with the Mikrotik installation and the application of load balancing in Mikrotik. The next steps are testing of the load balancing system which is carried out by technical testing of the implementation. The process includes testing the speed, the function, and optimization of the load balancing. The result shows that the use of load balancing system can be applied optimally. When network traffic increases due to the distribution of balanced connection lanes, it can run without changing the existing network and makes the connection run more optimal.
