Abstract

This study aims to analyze the performance of three prediction models, namely K-Nearest Neighbors (K-NN), Neural Network (NN), and Support Vector Machine (SVM), in predicting the stock price of PT Astra International Tbk (ASII.JK). The research encompasses the initial stages through evaluation using optimal parameters for these three algorithms. The research findings reveal that the K-NN prediction model has the lowest Root Mean Square Error (RMSE) value, with a value of 0.037, indicating the most accurate prediction compared to the other models. Despite the NN model having an RMSE of 0.048, which is higher than K-NN, it still provides reasonably accurate predictions. Meanwhile, the SVM model has an RMSE of 0.075, indicating a higher level of error in its predictions. Based on these results, the recommendation is to utilize the K-NN model as the preferred choice for predicting the ASII.JK stock price.

Abstract

Speeches are a more formal and focused means of communication, allowing the audience to listen more intently to what the speaker is saying. Speech acts are an important aspect of language study. This study aims to describe and analyze the forms of directive speech acts used by President Prabowo in his speeches. The method used is a descriptive qualitative method with a listening and note-taking technique on the research data in the form of utterances obtained from videos of President Prabowo's speeches uploaded to the YouTube platform. The results of the study indicate that the dominant directive speech acts that appear are questions, orders, and prohibitions on the use of these speeches aimed at state officials to take concrete action in disaster management. These directive speech acts function as a tool of social control, strengthening leadership ethics, and a means of affirming the president's stance on symbolic practices that do not directly impact disaster victims.

Abstract

    This study examines the impact of financial literacy (the ability to understand and manage financial concepts) and financial technology (the use of digital tools to record, manage, and report finances) on the quality of financial reports (relevance, consistency, accuracy, and timeliness). Using a quantitative approach through a questionnaire survey of accounting students, the analysis includes validity, reliability, classical assumptions, and multiple linear regression tests. Results: Financial literacy has a significant positive effect on report quality; financial technology is not partially significant; together, the two contribute 34.8%, with the remainder influenced by other factors. This study is expected to enrich accounting theory and provide practical guidance for improving reporting standards.

Abstract

The increasing complexity of organizational processes has intensified the need for effective audit quality control to ensure reliable and accountable audit outcomes. Audit Information Systems (AIS) have emerged as a critical tool in supporting internal audit activities, particularly in managing audit findings and enhancing audit quality control. However, empirical evidence regarding the effectiveness of audit information systems in improving audit quality control remains limited, especially in the context of internal audits. This study aims to examine the effect of audit information systems on audit quality control, with particular attention to the management of audit findings. The research adopts a quantitative approach using data collected from internal auditors through structured questionnaires. Statistical analysis is employed to assess the relationship between audit information systems, audit findings management, and audit quality control. The results indicate that audit information systems have a significant positive effect on audit quality control by improving data accuracy, consistency, transparency, and timeliness of audit processes. Furthermore, effective management of audit findings through information systems contributes to enhanced audit accountability and compliance with audit standards. These findings highlight the strategic role of audit information systems in strengthening internal audit functions and supporting organizational governance. The study contributes to the literature on audit information systems and provides practical implications for audit institutions seeking to improve audit quality control through digital transformation.

Abstract

This research looks at how Google Business Profile (GBP) makes people want to go to and buy from coffee shops, using the Pleasure–Arousal–Dominance (PAD) Theory, the Theory of Planned Behavior (TPB), and the Quality–Intention Framework. Information gathered from surveys of 226 users was examined using a method called partial least squares structural equation modeling (PLS-SEM) to understand how feelings and thoughts affect what people plan to do. The findings show that what GBP looks like affects people's feelings and what they think, which then makes them want to do things in the real world. By combining PAD, TPB, and ideas about quality and intentions, this study gives a new way to understand how finding things online through GBP turns into what people do in person. Key words: Google Business Profile, PAD Theory, Theory of Planned Behavior, Quality–Intention Framework, Purchase intention, Café industry Paper type Research paper

Abstract

Anemia during pregnancy is a health problem that threatens both mother and fetus. A systematic review was conducted of relevant studies to determine the factors that cause pregnancy anemia and how to prevent it. The method used is a literature study using flowchart prisms from various sources. The results showed that maternal age, number of parities, nutritional status, rural residence and economic status, diet during pregnancy, and adherence to iron tablet use contributed to pregnancy anemia. To prevent anemia in pregnancy, women aged <20 years and >35 years or who have SEZ can postpone their pregnancy. Prevention can also be done through health services in the form of health centers that have good health management to realize the health of pregnant women by organizing and planning health services.

Abstract

Penelitian ini dilatarbelakangi oleh pembelajaran teks biografi masih sering disampaikan dengan metode konvensional seperti ceramah, membaca buku teks, dan mengerjakan lembar kerja. Hal ini menyebabkan rendahnya minat dan motivasi belajar siswa karena materi terasa monoton dan kurang relevan dengan keseharian mereka. Adapun tujuan penelitiannya adalah mendeskripsikan pemanfaatan media digital dalam pembelajaran teks biografi. Penelitian ini merupakan penelitian kualitatif deskriptif. Data dalam penelitian ini adalah hasil observasi dan hasil wawancara mengenai penggunaan media digital dalam pembelajaran teks biografi. Sumber data dalam penelitian ini yaitu siswa dan guru yang terlibat dalam pembelajaran teks biografi menggunakan media digital. Teknik pengumpulan data dalam penelitian kualitatif ini menggunakan dua metode utama, yaitu observasi dan wawancara. Teknik analisis data yang digunakan mengacu pada model Miles dan Huberman, yang mencakup tiga komponen utama: reduksi data (data reduction), penyajian data (data display), dan penarikan kesimpulan/verifikasi (conclusion drawing/verification). Hasil penelitian menunjukkan berdasarkan hasil observasi bahwa pemanfaatan media digital dalam pembelajaran teks biografi memberikan dampak yang sangat positif terhadap proses pembelajaran. Hasil wawancara juga menunjukkan pembelajaran menjadi lebih menarik dan tidak membosankan. Penggunaan Wordwall, youtobe, dan canva membuat siswa lebih aktif, antusias, mampu menjawab pertanyaan yang diajukan guru, dan kelas terasa menyenangkan. Jadi disimpulkan, pemanfaatan media digital dalam pembelajaran teks biografi memberikan dampak yang positif dan signifikan terhadap proses pembelajaran dan hasil belajar siswa.
