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

The significant increase in the number of users has caused public opinion on the Ruang Guru application to be widely spread through social media, especially Twitter. From 15,000 twitter data taken with the keyword Ruang Guru, a total of 2,358 datasets were obtained through the process of handling duplicates. In this study, sentiment analysis was carried out using the Support Vector Machine (SVM) algorithm which was optimized with Particle Swarm Optimization (PSO) then tested using the 10-Fold Cross Validation method which resulted in the highest accuracy rate of 89.20%, while the Support Vector Machine algorithm (SVM) only produces the highest accuracy rate of 88.56%. There is an increase of 0.64% with Particle Swarm Optimization optimization. Sentiment analysis results are positive, with positive results as much as 1463 data or 62.04% and 895 or 37.96% negative sentiment. From the results of this study, it is expected to be a material consideration for Ruang Guru to improve the quality of the service sector found on social media, especially Twitter.

Abstract

The rapid accumulation of waste in Indonesia's rivers, particularly the Cisadane River, seriously threatens water quality, ecosystem health, and public well-being. Traditional waste monitoring methods are inefficient and often fail to deliver timely data for effective interventions. This study addresses this gap by proposing an AI-based waste detection system for real-time water quality monitoring using deep learning techniques. A hybrid model integrating Convolutional Neural Network (CNN) and You Only Look Once version 7 (YOLO v7) was developed and tested on a dataset of 10,000 annotated images—60% organic and 40% inorganic waste—collected from the Cisadane River. The CNN model achieved a classification accuracy of 87%, a precision of 84%, a recall of 86%, and an F1-score of 85%. The YOLO v7 model demonstrated % detection accuracy of 82% with a processing speed of 20 frames per second. While mean Average Precision (mAP) was not directly calculated, the model's performance across key metrics supports its real-time applicability. This research offers a scalable and cost-effective approach for river waste monitoring and highlights the potential of AI in supporting sustainable environmental management in Indonesia.

Abstract

The adoption of technological advancements has strengthened the role of information technology (IT) in organizational operations. While IT provides various benefits, it also creates environmental challenges, such as high energy consumption and increasing electronic waste (e-waste). The International Energy Agency (IEA) reports that data centers and IT networks consume 1% of global energy, yet only 17.4% of e-waste is recycled. Therefore, a sustainable IT management approach is crucial. Green IT integrates sustainability principles into IT management to improve energy efficiency, waste reduction, and eco-friendly technology adoption. However, challenges such as unclear guidelines, infrastructure limitations, and low organizational awareness hinder its implementation. This study aims to design a Green IT framework suited to Indonesia’s context, using literature reviews, stakeholder interviews, and case studies. The findings will provide organizations with structured guidance to reduce environmental impact, improve efficiency, and enhance competitiveness in the digital era

Abstract

This study discusses customer segmentation strategies based on purchasing behavior and brand preferences for information technology products at PT. XYZ. The main objective of this research is to identify customer purchasing patterns and classify them into several segments with different characteristics. The historical transaction data used includes attributes such as the brand of purchased products, purchase frequency within one year, and total transaction value. After the data cleaning and normalization process, a centroid-based clustering technique was applied to identify homogeneous groups in the database. The clustering results show three main clusters, each representing different consumer behaviors in terms of brand loyalty, price sensitivity, and spending level. The analysis indicates that customers with high transaction values tend to select specific brands and make purchases more frequently. These findings provide strategic insights for the company in designing more personalized marketing approaches, improving the effectiveness of product offerings, and strengthening relationships with customers in each segment.

Abstract

Kompleksitas dan volume laporan keuangan perusahaan yang terus meningkat menjadi tantangan bagi analis dan pemangku kepentingan dalam menginterpretasikan informasi secara cepat dan akurat. Analisis manual cenderung memakan waktu lama dan rentan terhadap kesalahan. Penelitian ini mengusulkan sistem otomatis untuk melakukan peringkasan laporan keuangan berbasis PDF dengan menggunakan metode Natural Language Processing (NLP) berbasis Transformer. Sistem dikembangkan menggunakan Python serta memanfaatkan PyPDF2/pdfplumber untuk ekstraksi teks, NLTK untuk prapemrosesan, dan model BART/T5 dari Hugging Face Transformers untuk menghasilkan ringkasan. Evaluasi dilakukan pada laporan tahunan perusahaan multinasional dengan panjang 50–200 halaman. Hasil pengujian menunjukkan sistem mampu mereduksi teks hingga 10–15% dari panjang asli, dengan nilai rata-rata ROUGE-1 = 0,72; ROUGE-2 = 0,62; dan ROUGE-L = 0,70. Ringkasan yang dihasilkan mempertahankan informasi penting seperti tren pendapatan, laba bersih, beban operasional, dan arus kas. Pendekatan ini dapat mempercepat analisis keuangan, mengurangi beban kognitif analis, serta menghasilkan ringkasan yang konsisten. Ke depan, penelitian dapat dikembangkan dengan fine-tuning model pada korpus keuangan serta integrasi analisis sentimen untuk memperkaya interpretasi manajerial.

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
