Abstract

Flawless performance evaluation results across all service dimensions may potentially obscure the identification of areas for improvement and diminish objectivity in decision-making. This study aims to identify the specific service attributes influencing public satisfaction and to segment respondents based on their satisfaction levels at the Office of the Ministry of Religious Affairs in Payakumbuh City. The research integrates Principal Component Analysis (PCA), K-means clustering, and linear regression. PCA was employed to reduce data dimensionality and establish principal components; K-means clustering was utilized to group respondents based on perceptual similarities regarding service quality; and linear regression was applied to identify the most significant factors influencing public satisfaction within each segment. The data were sourced from the Public Service Survey Information System (SISULAP) application of the Payakumbuh Ministry of Religious Affairs, spanning June 2024 to October 2025, with a total of 1,950 respondents. The findings reveal that service process and efficiency are the primary factors influencing all respondent segments, with the low-satisfaction segment identified as the top priority for service improvement. The regression models demonstrate robust performance across all segments. These findings provide an empirical foundation for data-driven policymaking to enhance public service quality.

Abstract

The development of information technology has had a significant impact on the education sector by providing data-driven tools to support the process of major selection. This process often causes confusion among students due to its crucial role in determining their academic and career futures. This study aims to develop an accurate and transparent recommendation system for major selection through the integration of Principal Component Analysis (PCA), Random Forest (RF), and SHAP. The research follows a systematic framework that includes data processing and model evaluation stages. PCA is applied to reduce the dimensionality of complex student data in order to improve computational efficiency and minimize information redundancy. Furthermore, the Random Forest algorithm is employed as a classification model to predict major recommendations such as Science, Social Sciences, and Religious Studies. The SHAP method is integrated to provide both mathematical and visual interpretations of the contribution of each academic feature to the model’s prediction results. The research data are obtained from the internal records of MAN 1 Payakumbuh covering the last three academic years (2022/2023–2024/2025). The dataset consists of 571 eleventh-grade students with tenth-grade academic scores and non-academic skill variables. The implementation of this model is able to provide more objective recommendations compared to conventional subjective assessments, achieving an accuracy of 88.70%. Visualization of feature contributions using SHAP enhances transparency and facilitates stakeholders’ understanding of the basis for each model decision. This study contributes to improving the efficiency of the major selection process and supports more accurate academic decision-making for students and educators.

Abstract

Pada penelitian ini dilatarbelakang oleh dimana banyaknya ulasan pengguna aplikasi SFID yang berisi keluhan dan penilaian dengan bahasa yang beragam sehingga sulit dianalisis secara manual, cepat dan objektif. Kondisi tersebut menyebabkan informasi penting terkait pengalaman pengguna, kendala teknis, dan kualitas layanan aplikasi belum dapat dimanfaatkan secara optimal sebagai dasar pengambilan keputusan pengembangan aplikasi. Dengan demikian, penelitian ini bertujuan untuk mengelompokkan dan mengklasifikasikan ulasan pengguna aplikasi Mitsubishi SFID secara sistematis guna mendukung proses pengambilan keputusan. Dalam penelitian ini, Metode K-Means Clustering digunakan untuk mengelompokkan ulasan berdasarkan tingkat kemiripan karakteristik dan tema, sedangkan algoritma C4.5 diterapkan untuk mengklasifikasikan ulasan pada setiap kelompok ke dalam kategori tertentu berdasarkan atribut yang relevan. Data yang dianalisis berasal dari ulasan pengguna aplikasi Mitsubishi SFID yang diperoleh melalui platform Google Play Store. Penelitian ini menunjukkan bahwa model klasifikasi yang dibuat berhasil memberikan tingkat akurasi yang baik serta hasil validasi menunjukkan bahwa model memiliki kinerja yang stabil dan dapat diandalkan dalam mengklasifikasikan ulasan pengguna dengan nilai akurasi 88,89%. Dampak dari penelitian ini adalah tersedianya informasi terstruktur mengenai permasalahan dan kebutuhan pengguna yang dapat dimanfaatkan sebagai dasar penentuan prioritas perbaikan fitur, peningkatan kualitas layanan aplikasi, serta membantu mengambil keputusan yang lebih tepat dan didasarkan pada data

Abstract

Hate speech (HS) is defined as speech that conveys hateful meaning and intent. In contemporary times, the prevalence of hate speech has surged in the virtual realm, particularly on social media platforms. Among these platforms, Twitter, now renamed X, stands out as one of the most widely used and a significant medium for the dissemination of hate speech. Hate speech can be categorized into various levels of severity, including HS_Weak, HS_Moderate, and HS_Strong. This study utilizes a dataset comprising 13,169 tweets from the social media application X from Indonesia users in 2023 to investigate hate speech detection. The research employs a novel hybrid approach that integrates image input with five preprocessing techniques: data cleaning, case folding, tokenization, stop-words removal, and stemming. Following preprocessing, the study applies Natural Language Processing (NLP) techniques in conjunction with Naïve Bayes classification. The combination of these NLP methods proves to be highly effective for the classification of text data. The key findings of this research demonstrate that the hybrid method significantly enhances hate speech detection accuracy. The evaluation of the classification model, based on training and validation, reveals an accuracy rate of 80%, a precision value of 85%, a recall value of 75%, and an F1-score of 80%. These results indicate substantial improvement over previous research outcomes. The findings suggest that the hybrid method is robust and effective for hate speech detection on social media platforms. Future research should explore the comparison of this hybrid approach with other classification methods to further validate its efficacy and potential applications in various domains of text classification.

Abstract

Background: Early childhood education plays an important role in supporting children’s cognitive, social, and emotional development. However, many kindergartens and early childhood education teachers continue to rely on conventional storytelling approaches and have limited experience in utilizing digital and artificial intelligence (AI)-based technologies for learning activities. Contribution: This community service program contributes to teacher professional development by introducing EduStory-Gen, an AI-assisted storytelling platform that integrates narrative generation and visual illustration creation. Method: The program employed a participatory training approach involving 30 kindergarten and early childhood education teachers. The activities included needs analysis, training preparation, pre-assessment, hands-on training, mentoring, and post-training evaluation. Results: The results showed substantial improvements in teachers’ competencies related to digital storytelling and AI-assisted educational tools. The average competency score increased from 2.9 in the pre-assessment to 4.4 in the post-assessment. The highest improvement was observed in teachers’ knowledge of AI-based tools (+1.7). Conclusion: The EduStory-Gen training program effectively enhanced teachers’ digital storytelling competencies and AI literacy while fostering positive learning experiences. The findings highlight the potential of AI-assisted storytelling tools to support innovative teaching practices and strengthen technology integration in early childhood education.
