Abstract

This research aims to improving the accessibility and management of health information on the Ministry of Health (Kemenkes) website. Before this research was conducted, content on the Ministry of Health's website was scattered without a clear structure, making it difficult for users to find the health information they needed quickly and efficiently. This results in a decrease in the quality of the user experience and a potential decrease in trust in official health information sources. With the aim of making it easier for users to find relevant information, this research uses the K-Means algorithm to group website content based on themes. Through the text mining method, five main clusters were identified, covering topics such as emergency health, certain diseases, and innovations in handling COVID-19. The results show an increase in navigation efficiency with clustering accuracy reaching 72%. The conclusion of this research is that this grouping succeeded in improving the structure and quality of information on the Ministry of Health's website, supporting data-based decision making, and improving public health services.

Abstract

Dyslexia occurs worldwide despite the culture or language. Dyslexia affects about 9% - 12% of the population, with 2% - 4% of the population experiencing significant reading impairments. This research aims to develop an artificial intelligence-based application using the Image-to-Speech method that can convert digital text into audible sound for individuals with dyslexia without requiring their brain to process the writing. This method can assist people with dyslexia in daily life challenges such as reading traffic signs, books, or documents. Results from 10 experiments on the implementation of the proposed method indicate that individuals with dyslexia can scan the text they want to read using a camera from a smartphone or laptop. The expirements also shows that the application can convert text in image form into sound comprehensible to those with dyslexia, thus facilitating their recognition of digital writing with 90% accuracy. The application also demonstrates efficiency in terms of data processing time. The average time required for image to audio conversion is 0.22 seconds, with an average memory usage of 163.2 MiB.

Abstract

This study evaluates the performance of hybrid machine learning models, specifically Random Forest and XGBoost, in classifying human DNA sequences into seven functional classes. Utilizing advanced feature vectorization techniques, this research addresses the challenges of analyzing high-dimensional genomic data. Both models were trained and tested on a dataset of annotated human DNA sequences, with an emphasis on generalizability to new, unseen data. Our results indicate that the Random Forest model achieved an accuracy of 87.98%, slightly outperforming the XGBoost model, which recorded an accuracy of 87.06%. These findings underscore the effectiveness of employing traditional machine learning techniques coupled with innovative data preprocessing for predictive modeling in genomics. The study not only enhances our understanding of genomic functionalities but also suggests robust methodologies for future genetic research and potential applications in personalized medicine. The implications of these results for improving classification accuracy and the recommendations for integrating more complex algorithms are also discussed

Abstract

Human DNA sequence classification is a fundamental task in genomics, essential for understanding genetic variations and its implications in disease susceptibility, personalized medicine, and evolutionary biology. This study proposes a novel hybrid model combining Convolutional Neural Networks (CNN) for feature extraction and Random Forest classifiers for final classification. The model was evaluated on a dataset of human DNA sequences, with achieving an accuracy of 75.34%. The results showed that performance metrics, including precision, recall, and F1-scores across multiple classes, showed significant improvements over traditional models. The CNN component effectively captures local dependencies and patterns within the sequences, while the Random Forest classifier handles complex decision boundaries, resulting in enhanced classification accuracy. Comparative analysis demonstrated the superiority of our hybrid approach, with the CNN-LSTM model achieving only 59.47% accuracy, and other RNN-based models like CNN-GRU and CNN-BiLSTM performing similarly lower. These results suggest that hybrid models can leverage the strengths of both deep learning and traditional machine learning techniques an offering a more effective tool for DNA sequence classification. The future work will optimize model architecture and explore larger, thus more diverse datasets to validate our approach's generalizability and robustness.

Abstract

Learning the Javanese script used in the Javanese language is challenging, especially for those who are just starting to learn the language. Students and the general public rarely use or are interested in Javanese script because of its difficulty. In order to protect the local language, researchers came up with the idea of teaching Javanese script to students, especially students who are just starting to learn in elementary school. This is done by creating a learning media application that is interesting, easy to understand, and entertaining. This Javanese script learning application is made using Augmented Reality (AR) technology and penanda-based tracking mechanism. This program is a learning tool that can turn 2D objects into 3D objects and bring the virtual world into the real world because it uses Augmented Reality technology. When used with the app's quiz feature, this educational tool can help elementary school students to improve their memory and skills, as well as inspire them to learn more through engaging instructions. The app was tested through blackbox testing to demonstrate its feasibility, with 100% successful results for all intended buttons and functions. AR camera distance testing resulted in a 90% success rate in detecting penandas at a certain distance.

Abstract

The determination of a toddler's nutritional status involves calculating weight and height based on age. Naïve Bayes is a machine learning algorithm for classification problems in data mining that utilizes probability mathematics (also known as Bayes' theorem) to distinguish between different classes. This system is designed to facilitate the nutrition staff at the Pajar Bulan Village Health Center in more accurately storing data and automatically determining the nutritional status of toddlers. The system is developed using the Rapid Application Development (RAD) method, which comprises three phases: requirements planning, design workshop, and implementation. The classification system for toddler nutritional status using the Naive Bayes algorithm aims to provide more accurate information to address malnutrition in toddlers. The data processing with the Naive Bayes algorithm results in the development of a system for classifying the nutritional status of toddlers at the Pajar Bulan Village Health Center.

Abstract

This research aims to analyze the comparison of customer satisfaction between the use of coaxial cables and fiber optic cables in PT.LinkNet using the Bandwidth method. The Bandwidth method was used to evaluate network performance and the quality of service received by customers. Data was collected through customer satisfaction surveys covering aspects of service reliability, speed, stability and price. The analysis results indicate a notable difference in customer satisfaction levels between the two types of cable. Fiber optic cables received higher satisfaction ratings compared to coaxial cables.The results shows that the average satisfaction score for fiber optic cables was 4.7 out of 5, whereas coaxial cables received an average score of 3.9 out of 5. This difference is significant since evidenced by a p-value of less than 0.01, confirming that the higher satisfaction with fiber optic cables is not an outcome of random variation. These findings can provide input for PT Link Net in improving service quality and choosing the right technology to meet customer needs.

Abstract

Stunting in toddlers must be addressed immediately because it has a negative impact on their growth and development. Stunting is a disorder where toddlers experience chronic malnutrition, thus their physical growth and height do not match their age. According to the Indonesian Nutritional Status Survey (SSGI), stunting is more common among toddlers from aged 0 to 1 year than overall. Stunting can have short-term and long-term impacts. This research examines data from the Temanggung District Health Service on 3,999 toddlers aged 0 to 12 months between 2019 and 2022.  Many studies have exclusively looked at stunting in children aged one to five years, especially research on stunting using the KNN method, even though stunting can actually be recognized from an early age. Therefore, researchers are more specific in using the KNN method for cases of babies 1 to 12 months so as to differentiate it from previous researchers. The aim of this research is to use the K-Nearest Neighbor (KNN) algorithm to detect stunting nutritional status in toddlers. K-Nearest Neighbor (KNN) is a classification algorithm that uses a set of K values ​​from the closest data (its neighbors) as a reference to determine the class of incoming data. KNN classifies data based on its similarity or closeness to other data. The dataset used includes parameters of age, gender and height. The research approach is the CRISP-DM (Cross Industry Standard Process for Data Mining) method, which begins with business knowledge, followed by EDA and modeling, evaluation, testing and report preparation. The result shows that the KNN algorithm can accurately categorize children as stunted or not based on age (U) and height (TB), with the maximum level of accuracy and the lowest error rate at k = 5. At this optimal value (k), this algorithm has an accuracy of 99.87%, Recall 99.84%, and precision 99.73.

Abstract

The rapid development of technology has changed many aspects of the data communication process, especially in cloud computing. Cloud computing or commonly known as cloud computing is now widely used. With the increase in cloud usage, there is a significant increase in traffic and causes a load imbalance between servers in the cloud environment. To overcome load imbalance on cloud servers, this research proposes the use of load balancing with a round robin method. Load balancing divides traffic equally between servers to prevent overload and system failure. The round robin algorithm ensures fair distribution by sending requests alternately to available servers. Testing shows a significant reduction in error rates when using load balancing. As many as 30 thousand users per second, the error dropped to 42.37%, 50 thousand users per second caused an error of 66.31%, and 100 thousand users per second resulted in an error of 63.08%. This indicates increased system scalability and ability to effectively handle surges in user requests. Overall, implementing load balancing using the round robin method is able to improve system performance in handling high traffic in a cloud environment, maintain stability, and minimize the risk of failure.
