Abstract

This study aims to analyze stunting in children in Tangerang Regency using clustering methods such as k-means, Hierarchical Clustering with Agglomerative Nesting, and Density-Based Spatial Clustering of Applications with Noise (DBSCAN). Stunting is a significant health issue affecting child growth due to chronic malnutrition and recurrent infections. The research revealed that k-means produced the best clustering results with a Silhouette Score of 0.52, indicating its effectiveness in categorizing children based on age, nutritional status, and stunting risk. The k-means method identified three clusters: Cluster 0 (ages 46-55 months, good nutrition, no stunting), Cluster 1 (ages 9-18 months, varied nutritional status, high stunting risk), and Cluster 2 (ages 27-36 months, good nutrition, no stunting). The study suggests preventive actions such as balanced nutrition education, regular health monitoring, complete immunizations, and physical activity, alongside curative measures like nutritional consultations and supplements. The findings provide a framework for targeted preventive and curative interventions, enabling Tangerang Regency's health department to effectively address and reduce stunting rates.

Abstract

Drowsiness detection is crucial in maintaining the safety and alertness of individuals, especially in high-risk situations such as driving or operating heavy machinery. This research aims to develop a drowsiness detection system based on facial images using Convolutional Neural Network (CNN) with a focus on the AlexNet method and its comparison with ResNet. In this study, facial image data was collected from various conditions of drowsiness and normal conditions. Image preprocessing was performed to standardize the size and ensure consistent image quality. AlexNet and ResNet were implemented and trained using the image dataset to identify distinctive patterns that differentiate drowsy faces from faces in a normal state. The results of the experiments showed that the use of AlexNet and ResNet methods effectively detects drowsiness in facial images with high accuracy. However, there are performance differences between the two methods. ResNet demonstrated superior performance in certain conditions, while AlexNet showed advantages in other cases. This research contributes to the development of facial image-based drowsiness detection technology applicable in various fields, including smart vehicles and security systems. The comparison results between AlexNet and ResNet also provide valuable insights for selecting the most suitable CNN method for drowsiness detection applications based on facial images.

Abstract

The development of information technology and cloud computing has enabled organizations to manage large-scale data efficiently. PT XYZ, which is engaged in psychological testing for Driving Licenses (SIM), uses a web-based system with a MySQL database that has implemented master-slave replication. However, as the data volume increases to 4,000-5,000 entries per day, the system experiences performance constraints, especially in the speed of read and write queries. This study aims to optimize the performance of the MySQL database by adjusting the server configuration and specifications to improve system efficiency. The test results show that server specification settings, including processor speed, memory size, and replication configuration, play an important role in improving system performance. By adjusting the master and slave server configurations, the system shows a significant increase in database response time and operational efficiency. This optimization is expected to be a reference in the implementation and management of large-scale databases using MySQL replication.

Abstract

Layanan paylater telah menjadi fenomena signifikan dalam ekosistem keuangan digital Indonesia, menawarkan kemudahan akses pembiayaan konsumen namun sekaligus menimbulkan kekhawatiran terkait dampak multi-dimensinya. Lonjakan outstanding utang paylater yang mencapai Rp30,36 triliun pada 2024 dan tingginya angka impulse buying (6,4%) menunjukkan urgensi analisis komprehensif terhadap layanan ini. Penelitian ini bertujuan untuk menganalisis dampak multi-dimensi layanan paylater terhadap pertumbuhan ekonomi, perilaku konsumsi, dan risiko sosial di Indonesia, serta mengkaji implikasi regulasi dan literasi keuangan. Dengan menggunakan pendekatan kualitatif deskriptif melalui studi literatur sistematis, penelitian ini mengintegrasikan temuan dari jurnal akademik, laporan resmi, dan data industri yang diterbitkan pada periode 2019 hingga 2025. Hasil penelitian menunjukkan bahwa layanan paylater secara signifikan meningkatkan daya beli konsumen dan mendorong pertumbuhan pesat transaksi e- commerce. Namun, kemudahan yang ditawarkan paylater juga meningkatkan kecenderungan impulse buying dan perilaku konsumtif, terutama di kalangan generasi muda. Perubahan perilaku ini, apabila tidak diimbangi dengan literasi keuangan yang memadai, berpotensi menimbulkan utang rumah tangga yang tidak terkendali dan mengancam stabilitas keuangan nasional. Studi ini menegaskan pentingnya regulasi yang ketat dan edukasi keuangan yang komprehensif untuk memitigasi risiko tersebut. Penguatan kolaborasi antara regulator, pelaku industri, dan lembaga pendidikan direkomendasikan agar manfaat paylater dapat dioptimalkan sekaligus meminimalisir dampak negatifnya bagi konsumen dan sistem keuangan.
