Abstract

Indonesia is known for its rich diversity, encompassing ethnicity, religion, culture, customs, and traditional artifacts, including traditional weapons. Traditional weapons hold significant historical and cultural value in Indonesia. To preserve and represent knowledge about these traditional weapons, an ontology model is essential. Ontology serves as a knowledge base that can effectively capture and represent information. In this project, we developed an ontology model for traditional weapons in Indonesia using the Protégé ontology development tool. The METHONTOLOGY method guided the step-by-step development of the ontology model, providing detailed descriptions for each stage. The ontology model consists of 6 classes, 4 object properties, 1 data property, and 72 individuals. We conducted testing of the ontology model through SPARQL queries. By building this ontology model, our aim is to contribute to the preservation and documentation of Indonesia's cultural heritage related to traditional weapons. The ontology serves as a valuable resource for researchers, enthusiasts, and institutions interested in studying and promoting traditional weapons in Indonesia.

Abstract

Advances in information technology are currently driving an increase in the number of internet users. In the business world, technology plays an important role and can be considered as a basic necessity for today's entrepreneurs. Likewise, in the textile industry, especially Balinese songket craftsmen or entrepreneurs, it is very important to utilize digital platforms to assess the results of Balinese songket fabrics and manage various aspects properly such as quality, color and pattern, innovation, and price. Thus, this knowledge can be shared with the public, passed down from generation to generation, and promoted to both local and foreign tourists, thereby increasing industry recognition and contributing to the country's foreign exchange earnings. To achieve this, the use of ontologies as an information representation technique is highly favored. Ontologies can greatly facilitate the development of semantic applications, especially when dealing with the semantic web. The methodology used for the development of the ontology model in this study is a process that allows the reuse of existing ontologies in subsequent system development. The development of the ontology model in this study uses a software application called Protégé, which has shown promising results during the ontology evaluation stage in providing satisfactory answers to user questions.

Abstract

In recent years, audio content has seen a rise in consumption. The COVID-19 pandemic also contributes to the rise in consumption. In the survey that was conducted in 2021, more than 40% of people in France, Germany, and Spain have been listening to more audio content since the first restriction on COVID-19 came into place [1]. One of the rising startups in Indonesia that offers audio content with their original and exclusive content is Noice. To maintain their quality of service, it’s important to look into the reviews that were written for their application. To analyze the reviews, sentiment analysis and topic modeling can be used to extract the sentiment polarity and the topics that are discussed on each sentiment polarity [3]. In this study, XGBoost and Latent Dirichlet Allocation are used to analyze the reviews that were written in Google Play Store. The result of the sentiment analysis yielded accuracy, precision, recall, and F1-score of 87,5%, 84,8%, 79,4%, and 81,6%. While the topic modeling managed to extract 16 and 6 topics respectively for positive and negative reviews.

Abstract

Pneumonia, a prevalent lung disease globally, poses significant challenges in accurate diagnosis despite its severity. This paper proposes a novel approach leveraging Support Vector Machine (SVM) classification and Gray-Level Co-occurrence Matrix (GLCM) analysis on chest X-ray images to aid in pneumonia diagnosis. By extracting pneumonia-indicative features from digital X-ray images using Gray-Level Co-occurrence Matrix (GLCM) and employing Support Vector Machine (SVM) for classification, the study aims to enhance pneumonia diagnosis effectiveness, particularly crucial in regions with limited healthcare resources. The proposed method focuses on identifying characteristic patterns indicative of pneumonia in chest X-ray images and distinguishing between normal and pneumonia-affected images based on GLCM-extracted features. Furthermore, the study evaluates the impact of hyperparameter tuning using grid search on the proposed diagnostic system's performance, including accuracy, sensitivity, and specificity. By achieving these objectives, the research aims to contribute significantly to the development of more accurate and effective diagnostic tools for pneumonia, especially in resource-constrained areas.
