Abstract

Pomelo (Citrus maxima), one of Indonesia's native citrus fruits, possesses high economic value and is widely cultivated across various regions in diverse varieties such as Bali Merah, Cikoneng, Nambangan, Raja, Ratu, and Pangkep. Despite its potential, quality assessment of pomelo fruits is still mostly conducted manually based on physical characteristics, which may lead to subjective and inconsistent results. This study aims to develop a more objective and efficient method by utilizing the K-Nearest Neighbor (K-NN) classification algorithm within a data mining framework. Six key features were used as classification variables: peel pigmentation, surface smoothness, fruit softness, weight, skin thickness, and overall quality. The research used a dataset collected from the North Sumatra Plantation Office over the past five years (2020–2024), which was processed and analyzed using the Orange application. Evaluation of the classification model achieved promising results, with an accuracy of 86.0%, F1-score of 0.860, precision of 0.861, recall of 0.860, AUC of 0.834, and MCC of 0.720. Additionally, predictions on new data samples confirmed the model’s ability to classify high-quality pomelo fruits effectively. These findings highlight the effectiveness of K-NN as a decision-support tool for improving fruit quality assessment processes and support the integration of data mining in smart agriculture practices.

Abstract

Air pollution from fossil fuel-powered vehicles poses serious health risks. To reduce greenhouse gas emissions, electric vehicles (EVs) have emerged as a greener alternative. However, EV adoption in Indonesia still struggles, mainly due to low public acceptance. This study analyzes Indonesian public sentiment toward EVs and the key factors influencing it, using Natural Language Processing (NLP) with BERT for sentiment classification and Named Entity Recognition (NER) for identifying important entities. The BERT model performed well, with 71.71% accuracy, 83.56% precision, 71.71% recall, 75.59% F1-score, and a misclassification error of 28.29%, outperforming Naïve Bayes and LSTM. Sentiment analysis found that 48.45% of the public expressed negative sentiment, 30.60% neutral, and only 20.95% positive. NER identified influential factors including public events, opinions, company reputation, product quality, pricing, and location.These findings offer important insights for policymakers and industry players in designing strategies to boost EV adoption in Indonesia.

Abstract

Selecting the right Cook’s Assistant is a critical factor in ensuring smooth restaurant operations, including at Lucky Seafood Restaurant in Pematang Siantar. The existing recruitment process often lacks objectivity and consistency, highlighting the need for a technology-based solution to improve decision-making accuracy and efficiency. This study aims to develop a Decision Support System (DSS) using the Additive Ratio Assessment (ARAS) method to assist management in selecting the most suitable candidate. The system evaluates five criteria: work experience, communication skills, and work attitude (benefit criteria), along with adaptation time and error rate (cost criteria). The ARAS method involves normalization, weighting, and the calculation of utility and utility degree values. The results indicate that among eight candidates, AC_06 ranks highest with a utility score of 1.51518, followed by AC_04 and AC_08. The implementation of this system has proven effective in reducing subjectivity, expediting the selection process, and increasing the accuracy of identifying the best candidate aligned with the restaurant’s operational needs.

Abstract

Stunting is a nutritional deficiency that results in impaired growth and development in children. In Indonesia, the prevalence of stunting has emerged as a pressing public health concern. The government has implemented a series of measures to address the issue of stunting. However, the prevalence of stunting in 2023 showed only a marginal decrease of 0.1% compared to the previous year. The determination of an individual's nutritional status is contingent upon the utilization of the Standard Antropometry Table, which is predicated on the calculation of Z-Score limits. These limits are determined by the age, weight, and height of the subject. In order to prevent stunting, it is essential to conduct a timely assessment of the nutritional status of children. The objective of this study is to facilitate the detection of nutritional status using a system that incorporates a nutritional status assessment for children. This system is designed to detect stunting using a mobile interface, with a user interface based on XML and Android Studio. The developed system is capable of displaying the nutritional status of the child, the presence of stunting, and the child's growth patterns.

Abstract

Hypertension is a prevalent health condition and a major risk factor for cardiovascular diseases. Early detection and management are essential to prevent complications. This study aims to optimize the accuracy and stability of hypertension risk prediction by applying a stacked ensemble technique that combines multiple base classifiers—K-Nearest Neighbors (KNN) and Decision Tree (DT)—with Logistic Regression as the meta-learner. The dataset used was imbalanced, thus requiring class balancing with the Synthetic Minority Over-sampling Technique (SMOTE), along with data preprocessing and scaling. The study applies a quantitative approach to train and evaluate models using Python. Results demonstrate that the stacked ensemble model achieves superior performance compared to individual classifiers, with a maximum accuracy of 74.52%. These findings indicate that the combination of different classifiers through ensemble stacking enhances the reliability and predictive capability of hypertension detection models. The approach offers potential value for improving early diagnosis and supporting clinical decision-making.

Abstract

This study aims to classify public opinions on educational issues expressed through the social media platform Twitter using the Naïve Bayes Classifier algorithm. This method was chosen due to its capability to categorize text data into positive, negative, and neutral sentiment categories based on the assumption of attribute independence. The data used consists of a collection of tweets relevant to the topic of education, which were analyzed through the stages of preprocessing, feature extraction, classification, and model evaluation. The results of the study indicate that the model is able to classify opinions with an accuracy of 73% based on the Confusion Matrix. Further analysis shows a precision of 85% for the positive category, 79% for negative, and 88% for neutral, while the recall for the positive category reached 77%. These findings suggest that the Naïve Bayes algorithm is fairly effective in processing public opinion from social media and can serve as a reference for understanding public perceptions regarding educational issues.
