Abstract

The development of information and communication technology has changed the way of social interaction, especially among Generation Z. The increasing use of the internet in Indonesia, which will reach 79.5% in 2024, brings new challenges in the form of Online Gender-Based Violence (OGBV). This study aims to explore the condition of legal education related to OGBV and efforts to prevent and handle it. This study uses a qualitative approach with a descriptive study method. Data were collected through random sampling among Generation Z, by combining primary and secondary data from various sources such as books, articles, and reports. The analysis was conducted to describe the actual condition of legal education in the context of OGBV. The findings show that despite increased legal awareness and regulations in the law related to OGBV, cases of this violence are still increasing. Data from the National Commission on Violence Against Women shows a spike in reports of OGBV cases from 16 complaints in 2017 to 1,272 in 2023. The most common type of violence is the threat of spreading sexual content. Although regulations have been in place, their effectiveness in preventing OGBV is still questionable. This study emphasizes the importance of socialization and increasing legal understanding among individuals to address the issue of OGBV more effectively. Legal culture reform and community engagement are needed to create a safer environment for internet users.

Abstract

Accurate sales forecasting plays a critical role in inventory management, particularly for medical equipment companies where stock availability directly affects operational efficiency and customer service. However, many small and medium-scale distributors still lack reliable forecasting systems, resulting in overstocking, high storage costs, or stockouts that lead to missed sales opportunities. Addressing this gap, this study aims to develop a web-based sales prediction system for PT Etiqa Prima Utama—a medical equipment distributor in Padang, West Sumatra—by applying the Double Exponential Smoothing method. The system was designed using PHP and MySQL to generate monthly sales forecasts for various medical products based on historical data. Key findings show diverse forecast accuracy across 20 product categories. The Glucose HK product achieved the lowest MAPE value at 10%, indicating excellent predictive performance, while the Clean Chem product showed the highest MAPE at 54%. Several other products, such as Total Bilirubin (12%), Urea (10%), and Diluent 20L (14%), demonstrated favorable accuracy with MAPE values below 60%. These results imply that Double Exponential Smoothing can support inventory optimization by providing reasonably accurate forecasts for most products, enabling better stock planning and more informed decision-making within the company.

Abstract

Heart failure is a cardiovascular disease with a high mortality rate and tends to increase every year. Therefore, a method is needed that can help the process of classifying heart failure quickly and accurately. This study aims to design and implement a heart failure classification system using the K-Nearest Neighbor (K-NN) machine learning method. The dataset used consists of 918 patient data with eleven input variables and two output classes, namely patients diagnosed with heart failure and patients not diagnosed with heart failure. The research stages include data loading, dividing training data and test data, implementing the K-NN algorithm with various K values, and evaluating model performance using accuracy, precision, recall, and F1-score metrics. The test results show that variations in the K value have a significant effect on the performance of the classification model. The K value = 9 produces the best performance with an accuracy of 93.48%, a recall of 96.36%, and an F1-score of 94.64%, which indicates a good balance between precision and recall. Based on these results, the K-NN method with a value of K = 9 is recommended as the optimal configuration in the classification of heart failure disease in this study.

Abstract

Financial Technology (FinTech) has been a revolutionary force in the last ten years, especially in emerging economies that are working to expedite digital transformation and attain financial sustainability. This study examines how FinTech development affects financial sustainability, using institutional preparedness as a moderating variable and digital transformation as a mediating factor. The study uses fixed-effects panel regression analysis to investigate cross-regional dynamics using a panel dataset of 18 rising economies in Africa, the Middle East, and Southeast Asia from 2015 to 2025. FinTech development considerably improves financial sustainability, according to empirical studies (β = 0.42, p < 0.001), with digital transformation processes mediating about 38% of this benefit. This association is further strengthened by institutional preparedness, suggesting that regulatory frameworks and governance quality are crucial for maintaining FinTech-driven growth. Southeast Asia has the strongest correlation between FinTech adoption and sustainability, according to regional studies, whereas Sub-Saharan Africa's influence is still limited by policy and infrastructure constraints. The results highlight how FinTech may promote equitable and sustainable financial systems when it is backed by strong digital governance. It is recommended that policymakers advance financial literacy, improve digital infrastructure, and include ESG principles into FinTech regulations. This study advances our theoretical and practical knowledge of how FinTech may promote digital inclusion, economic resilience, and sustainable financial growth in developing nations.

Abstract

Stunting remains a critical nutritional issue among children, affecting growth and long-term human resource quality. Despite national programs and global targets for stunting reduction, early prediction of stunted children using data-driven methods remains limited. This study aims to evaluate and compare the performance of four supervised machine learning algorithms—Naïve Bayes, Multilayer Perceptron (MLP), Decision Tree (J48), and Support Vector Machine (SVM)—in predicting stunting using a dataset of 97 child records from three villages in East Kalimantan, Indonesia. Data were tested in both unnormalized and normalized forms and split into training and testing sets at 70%–30%, 80%–20%, and 90%–10% ratios. The results indicate that MLP and Decision Tree consistently achieved 100% accuracy across all splits and preprocessing conditions, while Naïve Bayes and SVM showed lower and more variable accuracy in certain cases. These findings suggest that MLP and Decision Tree are the most reliable methods for stunting prediction in small datasets, providing a practical approach for early identification and intervention. The study highlights the importance of algorithm selection and preprocessing in achieving optimal predictive performance in health-related datasets.

Abstract

The rapid development of information technology and artificial intelligence has increased the importance of data-driven decision-making, particularly in competitive industries such as cafés, where branch location significantly affects business success. However, selecting the optimal location remains a challenge due to the variability of local market conditions and the subjectivity of manual assessments, representing a gap in practical, objective evaluation methods. This study aims to determine the most suitable location for Anomali Café’s new branch in Padang City using the Simple Additive Weighting (SAW) method, a transparent and effective multi-criteria decision-making approach. The analysis of ten candidate sites reveals that Pantai Air Manis Street achieves the highest overall score, followed closely by Sitebal, Gajah Mada, Raya Lubuk Buaya, and Dr. Sutomo Streets, while the remaining locations are less competitive. These findings provide actionable, data-driven guidance for strategic branch expansion and demonstrate the applicability of SAW in tailoring location decisions to the café industry’s specific context.

Abstract

The effective teaching of power electronics is critical for developing engineers capable of addressing global energy challenges, yet a persistent gap exists between idealized theoretical models and the non-ideal behavior of physical systems. This gap undermines both technical proficiency and conceptual understanding in engineering education. To address this, our study implemented and evaluated an iterative research and development methodology focused on a fundamental power conversion circuit: the controlled half-wave rectifier. The primary objective was to quantify the simulation-reality discrepancy and to assess whether a cyclical process of modeling, simulation, physical deployment, and data-driven refinement could serve as an effective pedagogical framework. Our key findings reveal a quantifiable performance gap, with a consistent 1.67V forward voltage drop in the silicon-controlled rectifier (SCR) leading to output deviations of up to 38% from theoretical predictions at low firing angles, as rigorously analyzed using Mean Absolute Percentage Error (MAPE) and Root Mean Square Error (RMSE). Crucially, this technical investigation was seamlessly integrated with experiential learning. The iterative methodology resulted in a measurable 40% average improvement in student troubleshooting skills and conceptual mastery, while the entire prototype was realized for under USD 12, demonstrating a commitment to accessible and sustainable design. The implications of this work are twofold: it provides educators with a validated, replicable blueprint for a hands-on curriculum that bridges theoretical and practical knowledge, and it offers engineers a model for cost-effective prototyping that acknowledges and integrates component non-idealities from the outset. This research confirms that closing the simulation-reality gap is not merely a technical necessity but a foundational element of responsible and effective engineering education.

Abstract

One of the most serious issues in the current predictive modelling is overfitting, especially with the increase in the complexity and size of machine learning systems. This research proposes regularisation-based methods as critical methods of enhancing generalisation and avoiding noise memorization in training data by models. The systematic literature review of the study that includes 2006-2025 research provides the synthesis of classical regularization methods, including L1/L2 penalties, Elastic Net, dropout, and early stopping, and emerging methods, including probabilistic dropout variants, Bayesian regularization, adaptive regularizers, and hybrid frameworks. The review points to the importance of the regularisation in the context of increasing the performance of generalisation, enhancing robustness to noisy or finite-sized datasets, stabilising optimization dynamics, and interpretability in high dimensional computations. It also determines the major shortcomings in the extant research such as, lack of comprehension on implicit regularisation, the cross domain comparative assessment and the requirement of adaptive and automatic strategies of regularisation. The paper ends with the research recommendations and open directions of research that are meant to enhance the theory, diagnostic tools, and towards the practitioners to effective regularisation configurations under different data regimes. Altogether, this paper gives an integrative and holistic approach to regularisation as a core building block of constructing credible, robust and general predictive models.
