Abstract

This study was conducted at SMK Kesehatan Prima Indonesia, which integrates informatics subjects into its curriculum, although the main focus is on developing students' health competencies. The main challenge faced is the management of informatics learning outcomes, especially in grouping students based on their understanding and achievements, which has been done manually and inefficiently. This study aims to identify groups of student learning outcomes using the K-Means Clustering method and describe the differences between the groups formed. This study is an exploratory study with a quantitative approach. The results of the clustering analysis on grade 10 students showed the formation of three groups: high score groups (24 students), medium score groups (51 students), and low score groups (42 students). In addition, learning interest and use of IT devices were shown to have a significant influence on informatics learning outcomes. These findings confirm that the application of the K-Means algorithm can improve the effectiveness of teaching strategies by grouping students in a more structured manner based on their learning outcomes.

Abstract: The use of e-learning in non-formal education is increasingly important to support the improvement of access to learning, one of which is through the online platform. This study aims to analyze the quality of online services using WebQual 4.0 and Im-portance Performance Analysis (IPA) methods to evaluate the suitability between user expectations and perceptions. The research method used a quantitative approach by distributing questionnaires to active users, then analyzed using the WebQual Index to measure the overall quality of the system as well as the IPA to determine improvement priorities. The results showed that the quality of SeTARA Online was relatively good with a WebQual Index value of 0.798. However, there is still a gap between user expectations and satisfaction with a negative gap value of -0.238. The IPA analysis identified indicators in Quadrant I as priority improvements, especially in the aspects of service interaction and information presentation. These findings underscore the need for continuous development of features and technical support to optimize the user experience. The conclusion of this study suggests that there should be improvements in priority indicators to increase user satisfaction, as well as strengthen the effectiveness of online learning. Advanced research can expand variables, compare with other platforms, and combine quantitative and qualitative analysis methods for more comprehensive results.

Abstract

Abstract: Feature selection is a crucial process that is very important to improve the performance of machine learning models, in accordance with data preprocessing. The feature selection process can be considered as a global combinatorial optimization problem in machine learning, which reduces the number of features, eliminates irrelevant data, and produces acceptable classification accuracy. The purpose of this study is to predict or determine the results of the electrical installation operation feasibility test based on data and obtain attribute selection features, and obtain accuracy level results. The Particle Swarm Optimization (PSO) approach is used to select the right characteristics to determine the results of the electrical installation operation feasibility test because attribute selection is needed in data analysis, because the PSO method will increase accuracy than just SVM in determining attribute selection. If SVM is used with PSO, the accuracy value is 96% and AUC is 0.994%, while the SVM method produces an accuracy level of 94.89% and AUC of 0.994%. With this finding, the accuracy value increases by 2%, making it a very good categorization category. It has been proven that the use of Particle Swarm Optimization (PSO) based algorithms can improve and improve results.            Keywords: PSO; SVM; Certification Abstrak: Pemilihan fitur merupakan proses krusial yang sangat penting untuk meningkatkan kinerja model machine learning, sesuai dengan praproses data.

Abstract

This study aims to conduct a sentiment analysis of user reviews of the Honor of Kings game on Google PlayStore using the Naive Bayes (NB) algorithm and Support Vector Machine (SVM) as a machine learning approach. The research gap raised in this study lies in the lack of comparative studies that quantitatively measure the performance of the two classic algorithms on Indonesian-language mobile game review data, as well as the absence of numerical mapping of sentiment distribution that describes user perceptions proportionally. The dataset used consisted of 1000 reviews, which after the manual labeling process was divided into 780 positive reviews (52%), 540 negative reviews (36%), and 180 neutral reviews (12%). The quantitative objective of this study was to measure and compare the levels of accuracy, precision, recall, F1-score, and AUC of the two models to determine the most effective algorithm in classifying user opinions. The test results showed that the SVM model produced an accuracy of 75.3% with an AUC value of 0.82, while the NB model obtained an accuracy of 71.1% with an AUC of 0.78. Based on the confusion matrix, SVM is able to reduce misclassification of negative and neutral sentiments, which are generally difficult to distinguish due to the distribution of sparse text features. Scientifically, this study contributes by showing that SVM is more optimal than NB in handling unbalanced review data, and confirms the importance of feature weighting and AUC validation as indicators of model reliability. Practically, the results of this study can be used by the developers of Honor of Kings to evaluate aspects of the user experience based on the sentiment patterns identified, especially in improving server stability, character balance, and player satisfaction.Keywords— Sentiment Analysis, Naive Bayes, Support Vector Machine, Honor of Kings, Google PlayStore.

Abstract

Advances in information technology have a significant influence on various sectors, including Micro, Small, and Medium Enterprises (MSMEs). However, most MSMEs still have not adopted digital systems in their operational activities. One example is Warkop Diini Aja, which until now still applies manual recording to the cashier transaction process. The use of the conventional system poses various obstacles, such as delays in making reports, potential for recording errors, and difficulties in monitoring sales history. Based on these problems, this research aims to design a web-based cashier system that is able to replace manual methods to be more efficient and structured. System development is carried out using the Laravel framework with a waterfall software development model, which includes the stages of needs analysis, design, implementation, testing, and maintenance. Research data was obtained through direct observation of operational processes, interviews with business owners, and literature review to strengthen the theoretical basis. The developed system has two main roles, namely admin and cashier, which are equipped with menu management features, sales transactions, export reports in digital format, and transaction history monitoring. Based on the results of the User Acceptance Testing (UAT) test, all system functions are declared to run according to user needs. In addition, the results of the Usability testing Checklist show a user satisfaction rate of 95%, which is classified as very feasible. Thus, this website-based cashier system has been proven to be able to improve operational efficiency, make it easier to record transactions, strengthen financial report transparency, and support more modern and digital business management.

Abstract

In a corporate environment with various divisions and high data exchange activity, efficient and secure network management becomes crucial. PT. Justus Kimiaraya, as a distribution and production company, requires a network system capable of supporting inter-division data communication without compromising performance or security. This research aims to implement Virtual Local Area Network (VLAN) technology to enhance network segmentation and restrict inter-division access according to operational needs. The methods used include literature studies, analysis of existing network requirements, VLAN topology design using Cisco Packet Tracer, implementation of VLAN and Access Control List (ACL), and performance testing before and after implementation. The test results show that VLANs successfully separate data traffic between divisions, preventing interference. Additionally, ACLs implemented on the router effectively limit inter-VLAN access, especially for divisions not authorized to access certain services, such as switchs or other division networks.
