Abstract

Stunting is a chronic nutritional problem that remains a major public health challenge, particularly in developing countries such as Indonesia. It results from long-term nutritional deficiencies and can negatively affect physical growth, cognitive development, educational achievement, and future productivity. Early detection of stunting risk is essential to support timely intervention and improve child health outcomes. This study aims to develop and compare the performance of several machine learning algorithms for predicting stunting risk in toddlers using a large-scale nutritional dataset. The dataset was obtained from the Kaggle repository entitled “Stunting Balita Detection (121K Rows)” and consists of 120,999 records containing age, gender, height, and nutritional status information. Data preprocessing included categorical data encoding, Min-Max normalization, and dataset partitioning into training and testing sets using an 80:20 ratio. Five classification algorithms were evaluated: K-Nearest Neighbor (KNN), Random Forest, Support Vector Machine (SVM), Naïve Bayes, and Decision Tree C4.5. Model performance was measured using confusion matrix analysis, accuracy, precision, recall, and F1-score. The experimental results showed that KNN achieved the highest performance with an accuracy of 99.94%, precision of 99.90%, recall of 99.93%, and F1-score of 99.92%. Random Forest achieved comparable results with an accuracy of 99.93%, while SVM, Decision Tree C4.5, and Naïve Bayes produced lower performance values. These findings indicate that KNN and Random Forest are highly effective for stunting risk classification and have strong potential to support intelligent decision-support systems for early detection and nutritional monitoring of toddlers.

Abstract

Hypertension is a chronic non-communicable disease often accompanied by comorbidities, which can increase complication risks and reduce patients' quality of life. Currently, the identification of comorbidities in hypertension patients is frequently conducted manually, making it time-consuming and highly dependent on healthcare workers' thoroughness. This study aims to develop a predictive model for hypertension comorbidities using a machine learning-based Random Forest algorithm, designed as an early screening tool for the general population. The research method follows the Cross-Industry Standard Process for Data Mining (CRISP-DM) framework, encompassing business understanding, data understanding, data preparation, modeling, evaluation, and deployment. Clinical data were collected from medical records, focusing on predicting eight primary comorbidities using a multi-label classification approach. Data preprocessing involved data cleaning, transformation, splitting into training and testing sets, and handling class imbalances. The Random Forest model was trained and evaluated using subset accuracy and hamming loss metrics. The results demonstrate that the Random Forest algorithm successfully predicts hypertension comorbidities with a subset accuracy of 0.3361 and a hamming loss of 0.1502, indicating robust performance for multi-label prediction. The model was successfully deployed into a Streamlit-based web application, enabling healthcare professionals to obtain direct prediction results. This system is expected to assist in the early screening and monitoring of hypertension patients.

Abstract

Mosques and mushallas are worship facilities with high congregational activity, requiring a secure, comfortable, and efficient door access system. Manual door operation often causes several problems, such as doors not closing properly, noise caused by slamming doors, and high physical contact between users and the door. This study aims to design and develop an automatic door system based on Passive Infrared (PIR) sensors and surveillance cameras integrated with Internet of Things (IoT) technology to improve security and convenience in mosque and mushalla environments. The research method used is Research and Development (R&D), consisting of system requirement identification, hardware and software design, prototype implementation, testing, and evaluation. The system uses PIR sensors or cameras to detect the presence of worshippers, microcontrollers such as Arduino, ESP32, or Raspberry Pi as the control center, and servo motors or DC motors as automatic door actuators. The system is also equipped with a real-time notification feature through Telegram to send information and visual documentation to administrators. The results show that the system is capable of detecting movement, automatically opening and closing doors, and sending notifications along with visual documentation in real time. The system improves user convenience, reduces physical contact with doors, and facilitates remote security monitoring by administrators. In addition, the use of ESP32-CAM is considered effective and economical for implementing IoT-based automatic door systems.

Abstract

The rapid growth of digital marketplace platforms such as Shopee, Tokopedia, and Bukalapak has transformed online business competition and increased the importance of data-driven sales analysis. Marketplace data, including product price, ratings, reviews, sales volume, views, and seller location, contain valuable information that can be utilized to predict product market potential. However, the large volume, heterogeneous characteristics, and dynamic nature of marketplace data make manual analysis inefficient. Therefore, this study aims to analyze and compare the performance of the C4.5 and K-Nearest Neighbor (KNN) algorithms in classifying marketplace sales potential. The dataset used in this research was collected through data scraping from Shopee, Tokopedia, and Bukalapak using the BigSeller application in March 2022, consisting of 21,750 product records with numerical and categorical attributes. Data preprocessing was conducted using Orange Data Mining, including data cleaning, missing value handling, normalization, feature transformation, and dataset partitioning. The classification process categorized products into three market potential levels: low, medium, and high. Model performance was evaluated using a confusion matrix based on accuracy, precision, recall, and F1-score metrics. The experimental results demonstrate that the C4.5 algorithm outperformed KNN, achieving an accuracy of 0.86, while KNN obtained an accuracy of 0.70. Moreover, C4.5 showed higher precision, recall, and F1-score values, indicating better classification consistency and stability. The findings suggest that C4.5 is more effective for marketplace sales potential classification due to its ability to identify influential attributes and manage heterogeneous marketplace datasets. This study contributes to marketplace sales prediction and supports data-driven decision-making in e-commerce environments.
