Abstract

Traditional Indonesian dishes often contain peanuts, coconut milk, and shrimp which are common allergens. However, allergen information is frequently absent from food vendors and digital recipe sites, posing potential health risks for individual with food allergies. This study presents an automated allergen detection system in Indonesian cuisine that uses a Logistic Regression model and has been trained on 14 primary allergen categories defined by the European Union. Each recipe is converted into a fixed-dimension binary vector using a bag-of-ingredients feature representation. As the evaluation results, the hyperparameter tuning approach significantly improved the model's performance. The model that was not fine-tuned only performed well in Scenario 1 (0 and 1) where it achieved an accuracy of 0.9995. In the Scenario 2 (0 - 3) Grid Search CV improved accuracy to 0.9997. In the Scenario 3 (0 - 14) Random Search achieved the best values with an accuracy of 0.9990 and a balanced precision-recall rate of over 0.97. Compared to the other methods, Random Search appears to be more adaptable to complex data distributions as these results show. Furthermore, this method has the potential to be widely applied to various culinary contexts like oriental and continental cuisines, which often uses high-allergen ingredients such as fermented soy products and dairy-gluten rich dishes. This system contributes to the advancement of food safety and public health through the integration of artificial intelligence in allergen detection.

Abstract

This study evaluates the role of computational pattern recognition as an observational method for analyzing morphological characteristics of brain tumor tissue in MRI data. A total of 6,056 labeled MRI images, including glioma, meningioma, and pituitary tumor cases, were examined. The images were standardized to maintain uniform structural representation and processed using three convolutional-based architectures: a baseline CNN, MobileNetV2, and EfficientNet-B0. Model performance was assessed using accuracy, precision, recall, F1-score, AUC-ROC, and a confusion matrix. The findings show variation in identification performance across tumor categories, with pituitary tumors consistently recognized, while misclassification predominantly occurred between glioma and meningioma. Models based on transfer learning achieved stronger agreement with the reference labels than the baseline CNN, with MobileNetV2 demonstrating the most stable performance. The recurrence of similar misclassification patterns across models suggests the presence of shared morphological characteristics in MRI representations of certain tumor types. Overall, the results support the use of computational image analysis as a structured observational framework that enables consistent evaluation of brain tumor tissue morphology in MRI, providing complementary insights for biological interpretation.

Abstract

Stopword is a word that can be ignored in the natural language process. This word removal process does not affect the text analysis process. The technique used to remove stopword is called Stopword Removal. This technique matches words to a stopword list. If the word is in the list it will be deleted. Javanese language to date still has a limited list of stopword. This study aims to form a list of stopword using cluster techniques namely K-medoids clustering. This technique groups words by occurrence in Javanese text. Each cluster result is tested by matching it with a stopword of javanese expert identification. The results of this study suggest that the stopword produced by k-medoids clustering with a value of K=13 has an accuracy of 70.5%. AbstrakStopword merupakan kata yang bisa diabaikan dalam permrosesan bahasa alami. Proses penghapusan kata ini ini tidak mempengaruhi proses analisis teks. Teknik yang digunakan untuk menghapus stopword disebut Stopword Removal. Teknik ini mencocokkan kata dengan daftar stopword (stoplist). Apabila kata tersebut terdapat pada daftar maka akan dihapus. Bahasa jawa sampai saat ini masih memiliki daftar stopword yang terbatas. Penelitian ini bertujuan membentuk daftar stopword menggunakan teknik cluster yakni K-medoids clustering. Teknik ini mengelompokkan kata berdasarkan kemunculan dalam teks bahasa Jawa. Dalam penerapannya, metode yang digunakan dalam penelitian ini terdiri dari lima tahap. Tahapan penelitian tersebut dimulai dari pengumpulan dataset, preprocessing data, clustering, dan terakhir adalah evaluasi. Setiap hasil cluster diuji dengan mencocokkannya dengan stopword hasil identifikasi ahli bahasa Jawa. Hasil penelitian ini menunujkkan bahwa stopword yang dihasilkan k-medoids clustering dengan nilai K=13 yang memiliki akurasi sebesar 70,5%.

Abstract

Cultural heritage knowledge presents significant challenges for Question Answering (QA) systems due to their interpretive, context-dependent, and symbolically rich nature. While Transformer-based models have achieved strong performance in semantic representation, they remain prone to hallucination and contextual misalignment, particularly in culturally sensitive domains. This study proposes a Transformer-based cultural knowledge retrieval framework for domain-specific chatbots, combining a bi-encoder (MiniLM and MPNet) for efficient semantic retrieval and a cross-encoder (BERT-base) for fine-grained reranking. A curated dataset of 4,016 question–answer pairs in Indonesia is developed from cultural heritage sources and validated for contextual consistency. The proposed approach is evaluated using both quantitative and qualitative metrics, including accuracy, F1-score, Exact Match (EM), and semantic-based measures such as F1-BLEU, F1-EDIT, and F1-ANS. Experimental results show that while all models achieve high classification performance (accuracy up to 0.99), the BERT + MPNet configuration significantly outperforms others in answer quality metrics, indicating superior semantic fidelity. However, qualitative analysis reveals persistent issues of hallucination and contextual misalignment, highlighting the limitations of relying solely on statistical evaluation. These findings demonstrate that high numerical performance does not guarantee meaningful understanding in cultural domains. Therefore, this study emphasizes the need for hybrid evaluation frameworks and context-aware mechanisms to ensure epistemic fidelity. The proposed approach contributes to the development of more reliable and culturally grounded QA systems.

Abstract

Estimating portion sizes and cooking times are goals for smart kitchen assistants, enabling better meal planning and reducing food waste due to over-portioning. Existing approaches in computational gastronomy often struggle to provide estimates from prepared ingredient data. This study uses XGBoost to extract features from a dataset containing 1,400 Indonesian recipes to predict binary classification targets for portion sizes and required cooking times. The dataset used for the prediction includes information on ingredients and their quantities, as well as preparation steps. In addition to the recipe dataset, the TKPI dataset is also used to help determine the category of food ingredients, protein content, and cooking technique complexity. This dataset is then further optimized with hyperparameters to maximize model performance. This paper conducted trials with 6 models where the best model for portion size had an accuracy of 0.7821 with a balanced accuracy of 0.4929, and an F1 Score of 0.8763, while the accuracy for cooking time was 0.6929 with a balanced accuracy of 0.6445, and an F1 Score of 0.7737. From the best model, it was found that the quantity of weighted ingredients and the distribution of ingredients per step were among the most influential features, while step-based and technique-based features were the most important features for cooking time. The contribution of this research is the development of an interpretable model for meal planning efficiency in culinary applications. These results indicate that feature aggregation combined with XGBoost provides actionable insights for smart kitchen assistants and recommendation systems.

Abstract

This study investigates the impact of contextual relevance and hyperparameter tuning on the performance of Transformer-based models in Question-Answer Generation (QAG). Utilising the FlanT5 model, experiments were conducted on a domain-specific dataset to assess how variations in learning rate and training epochs affect model accuracy and generalisation. Six QAG models were developed (QAG-A to QAG-F), each evaluated using ROUGE metrics to measure the quality of generated question-answer pairs. Results show that QAG-F and QAG-D achieved the highest performance, with QAG-F reaching a ROUGE-LSum of 0.4985. The findings highlight that careful tuning of learning rates and training duration significantly improves model performance, enabling more accurate and contextually appropriate question generation. Furthermore, the ability to generate both questions and answers from a single input enhances the interactivity and utility of NLP systems, particularly in knowledge-intensive domains. This study underscores the importance of contextual modelling and hyperparameter optimisation in generative NLP tasks, offering practical insights for improving chatbot development, educational tools, and digital heritage applications.

Abstract

Time series data in climatology and environmental research are highly susceptible to missing values that can disrupt temporal structures and degrade forecasting performance. This study evaluates the effectiveness of several imputation methods in improving the predictive performance of a Bidirectional Long Short-Term Memory model across three missing-data mechanisms: Missing Completely at Random, Missing at Random, and Missing Not at Random. The compared methods include mean, median, mode, k-nearest neighbors, multiple imputation by chained equations, and last observation carried forward, with data deletion serving as the baseline. All datasets were normalized using the min–max technique, and model hyperparameters were optimized through Particle Swarm Optimization. Performance was assessed using mean absolute percentage error, root mean square error, and the coefficient of determination. The findings indicate that proper imputation significantly enhances forecasting accuracy compared to deleting incomplete observations. In Dataset 1, the last observation carried forward achieved the best performance with a coefficient of determination of 0.923 and a root mean square error of 3.373. Similarly, Dataset 2 showed optimal results with the same method, producing a coefficient of determination of 0.950 and a root mean square error of 14.458. The most substantial improvement was observed in Dataset 3, where mean imputation reduced the mean absolute percentage error from 3.219 to 0.329 while increasing the coefficient of determination to 0.986. These results highlight the critical role of selecting an imputation strategy in deep learning-based time series forecasting and provide practical guidance for handling incomplete environmental datasets.

Abstract

Madurese slang on social media presents significant challenges for natural language processing due to its systematic yet unconventional alterations in spelling and pronunciation, for example, “bbh” becoming “pp” or “jh” turning into “cc”. Traditional string-matching techniques struggle with these transformations. This study evaluates four normalization approaches: standard string similarity models such as Jaro–Winkler and Levenshtein, Metaphone, hybrid strategies, and a novel heuristic-based method specifically designed for Madurese. We conducted experiments on a dataset of 105 slang–standard word pairs, assessing each method’s ability to accurately map slang to its standard form, both for top-1 and top-3 candidate matches. Results indicate that heuristic-based models significantly outperform generic methods. Notably, a combination of our heuristic approach with Levenshtein achieved 86.67% accuracy for Top-1 matches, while pairing the heuristic with Jaro–Winkler reached 91.43% accuracy for top-3 matches. These findings underscore the effectiveness of incorporating language-specific rules for normalization in morphophonemically complex, low-resource languages. Our proposed rule-based system offers a practical and adaptable solution for handling Madurese slang, highlighting the superiority of tailored heuristics over generic models in such contexts.

Abstract

Introduction: Kidney diseases remain a major global health challenge, and computed tomography (CT) provides detailed renal imaging that supports accurate diagnosis. Although data augmentation is commonly used to improve deep learning performance on limited medical datasets, the effects of different augmentation strategies on image characteristics and model learning behavior remain insufficiently understood. Method: This study evaluated spatial, intensity, and hybrid augmentation for kidney CT image classification using a custom CNN, MobileNetV2, and EfficientNet-B0. A public dataset containing 12,446 CT images across Normal, Cyst, Tumor, and Stone classes was partitioned using stratified sampling into training, validation, and test sets. Four scenarios—baseline, spatial, intensity, and hybrid augmentation—were evaluated across three independent random seeds using accuracy, precision, recall, F1-score, and AUC. Results and Discussion: The baseline achieved mean accuracies of 99.96%, 98.32%, and 94.06% for CNN, MobileNetV2, and EfficientNet-B0, respectively. Intensity augmentation slightly improved CNN accuracy to 99.99% and consistently produced smaller performance degradation and more stable convergence than spatial and hybrid augmentation. Spatial and hybrid transformations generally reduced classification performance, indicating that excessive geometric changes may disrupt diagnostically relevant anatomical features. Conclusion: Baseline training provided the best overall performance, while intensity augmentation was the most effective augmentation strategy, demonstrating that preserving anatomically meaningful image characteristics is more important than indiscriminately increasing data diversity.

Abstract

Dysgraphia features selection remains a challenge. Fisher’s criterion excels at highlighting the discriminative features of dysgraphia but lacks guidance for choosing the optimal number of features. Whereas Hill Climbing shows robust feature selection but often gets trapped in local optima. This study aims to avoid the Hill Climbing trap in local optima when selecting the best dysgraphia feature. Thus, the Fisher-Based Supervised Hill Climbing (FSHC) method is introduced. The contribution of this study is an optimized machine-learning-guided hill-climbing method that uses a classifier on a validation set as the objective function. A plateau mechanism also guided Hill Climbing exploration, not by a single Fisher point but by the neighboring subsets. The dataset used contains the graphomotor slant line task from 119 children aged 8-15 years (47.5% diagnosed with dysgraphia), with 10000 to 50000 data points per user. It is organized into kinematic, spatial, dynamic, and temporal features, yielding 117 sub-features. A stratified 5-fold cross-validation is set for training and testing, reaching 21 features. Comparative test—Linear SVM, SVM RBF, Sigmoid SVM, Polynomial SVM, Random Forest, AdaBoost, KNN, Decision Tree, Gradient Boosting, Gaussian Naive Bayes, and Gaussian Classifier—showed that linear SVM achieves the best performance with a weighted average precision, recall, and F1 score of 0.93. Linear SVM also outperformed the three approaches: no feature selection, the traditional Fisher, and machine-learning-based feature selection (weighted KNN and SVM). It can be concluded that the proposed method is more robust than the state of the art by highlighting key points for avoiding overfitting.
