Abstract

Customer satisfaction is an important reference in the sustainability of a business, as is the case with the computer training business at Radar Education Center which has competitors in its business. Until now there is no measuring tool for customer satisfaction at the Radar Education Center, this problem will be solved through the Decision Tree method using the C4.5 algorithm to analyze customer satisfaction. The data used comes from Radar Education Center customer data which consists of 80% training data and 20% testing data. After calculating accuracy using the Confusion Matrix, the Class Precision value was "yes" 83.33% and Class Recall "yes" was 100%.

Abstract

The development of a web-based company profile information system has become a fundamental need for organizations to increase reachability and direct customer involvement in it. In this context, structured software development methods and efficient frameworks become essential in ensuring project success. This article discusses the application of the Software Development Method (SDLC) and the Laravel Framework in developing a web-based company profile information system. The case study was conducted at CV Radar Teknologi Computer, a technology company engaged in providing software solutions. The SDLC method is used as a systematic approach to managing the entire information system development life cycle, from requirements analysis to testing and implementation. The Laravel framework was chosen to facilitate the development process by providing a strong structure and a variety of built-in features. The implementation results show the effectiveness of using SDLC and Laravel in achieving project goals in a timely manner and according to the desired specifications.

Abstract

Green IT is a cutting-edge information technology strategy designed to lessen the negative environmental effects of using IT infrastructure and devices. This study uses a qualitative methodology to investigate how Green IT is being adopted in different enterprises, emphasizing its advantages, difficulties, and practical implementation techniques. Document analysis and literature reviews from a range of sources pertaining to the adoption of green IT were used to gather data. According to the research, companies who use green IT see improvements in operational sustainability, lower carbon emissions, and increased energy efficiency. However, there are a number of significant obstacles to its adoption, including high upfront expenditures, ignorance, and reluctance to adopt new technologies. This report also emphasizes how crucial laws and rules are to encouraging the use of green IT. The study's conclusion highlights how putting Green IT into practice helps build a more sustainable and ecologically friendly technology ecosystem. As a result, companies must create all-encompassing plans for implementing Green IT, which should include purchasing energy-efficient equipment and increasing organizational understanding. This study helps policymakers, practitioners, and scholars better understand and support the future adoption of green IT.

Abstract

In the era of globalization, learning Chinese is increasingly important, but challenges such as low student attendance and learning quality are still significant problems. This article discusses the application of data mining techniques as a solution to analyze student attendance and improve the quality of Chinese learning. By collecting and analyzing attendance data from 200 students for one semester, through classification and visualization methods, this article identifies patterns that affect student attendance. The analysis results show that 65% of students who followed the interactive teaching method attended more than 80% of the total meetings, compared to only 40% of students who followed the traditional teaching method. In addition, it was found that 75% of students who received additional material for difficult topics experienced a 20% increase in average test scores compared to pre-intervention scores. Recommendations for improvement were made based on these findings, including adaptation of teaching methods and provision of supplementary materials. Through a case study of an educational institution that has successfully implemented this technique, this article shows that data mining can not only improve student attendance, but also significantly improve the quality of learning. This research is expected to encourage educational institutions to adopt data mining technology in an effort to improve students' learning experience.

Abstract

This study investigates the role of Knowledge Management System (KMS) implementation inenhancing the competitiveness of retail companies, with a specific focus on Lotte Mart Indonesia.Using a qualitative exploratory case study approach, the research collected data through in-depthinterviews, field observations, and company document analysis. The findings demonstrate that KMSaccelerates the flow of information, reduces duplication, and improves operational efficiency, therebyenabling better coordination among departments. Furthermore, KMS facilitates knowledge sharingand collaboration, which supports the development of service innovations and responsive marketingstrategies. Employees reported that the system allows faster access to documents, real-time inventorychecking, and more structured workflows. Beyond operational benefits, KMS contributes tostrengthening customer satisfaction through improved responsiveness and accurate informationdelivery. Additionally, KMS supports the company’s digital transformation by integrating internalsystems such as ERP, CRM, and e-commerce platforms. Overall, KMS functions not only as aknowledge repository but as a strategic enabler of sustainable competitive advantage in the retailsector.

Abstract

Fortigate FG-60F is one of the popular firewall appliances utilized by small and medium-scalenetworks in managing security. However, some of the needed features such as multiple interfacepolicies are not displayed by default on the user interface. This study explores the functionality andeffectiveness of enabling system-feature visibility for easier management of inter-interface policies.Employing an experimental approach, the Fortigate FG-60F device was configured to activate thehidden feature, and subsequently, a set of policy rule scenarios with multiple interfaces wereestablished and tested. The results indicate that supporting system-feature visibility enhancessignificantly the administrator's ability to implement more specific traffic policies that arecommensurate with network topology requirements. Moreover, performance analysis showed nonegative impact on device performance after the implementation of multi-interface policy. Thefindings are expected to serve as a valuable reference for network administrators in optimizingFortigate FG-60F security capabilities by leveraging advanced, previously hidden features
