Abstract

Arrhythmia is a heart disease that occurs due to a disturbance in the heartbeat that causes the heart rhythm to become irregular. In some cases, arrhythmias can be life-threatening if not detected immediately. The method used to detect is electrocardiogram (ECG) signal analysis. To avoid misdiagnosis by cardiologists and to ease the workload, methods are proposed to detect and classify arrhythmias by utilizing Artificial Intelligence (AI). In recent years, there has been a lot of research on the detection of this disease. However, many of such studies are more likely to use machine learning algorithms in the classification process, and most of the accuracy results still do not reach optimal levels in general. Therefore, this study aims to classify arrhythmias using deep learning algorithms. There are several stages of performing arrhythmia detection, namely, preprocessing, feature extraction, and classification. The focus of this research is only on the classification stage, where the Long Short-Term Memory (LSTM) algorithm is proposed. After going through a series of experiments, the performance of the proposed algorithm is further analyzed to compare accuracy, specificity, and sensitivity with other machine learning algorithms based on previous research, with the aim of obtaining an optimal algorithm for arrhythmia detection. Based on the results of the study, the Long Short-Term Memory (LSTM) algorithm managed to outperform the performance of other machine learning algorithms with accuracy, specificity, and sensitivity results of 98.47%, 99.24%, and 97.67%, respectively.

Abstract

Gingival carcinoma is a malignant neoplasm affecting the oral mucosa and is associated with significant morbidity and mortality. Allium ampeloprasum var. porrum water extracts have gotten a lot of attention because of their bioactive components, such as polyphenols, flavonoids, and alkaloids, which have a variety of pharmacological activities, including antiproliferative actions. This study aimed to evaluate the histological and molecular effects of Allium ampeloprasum (leek) water extract on the proliferation of the murine gingival cancer cell line. Histological evaluation was conducted to examine morphological changes induced by extract treatment. Molecular mechanisms underlying the observed histological changes were investigated using real-time polymerase chain reaction (PCR). Expression levels of key genes associated with cell proliferation and apoptosis were assessed. Histological findings revealed a dose-dependent decrease (100, 50, 25, 12.5, and 6.25 µg/ml) in cell density and altered cell shape in the treated cell line. Also, the percentage of inhibition for the oral mucosa cell line was high, with a significant P of 0.006, in the treated group compared to the control group. Additionally, water extract has an IC50 value of 61 g/ml. The P53 fold increment of gene expression is 0.6, which means the expression level in the experimental condition is 60% higher than the control. This study provides evidence for the potential antiproliferative activity of Allium ampeloprasum water extract on the oral mucosa cell line. The observed histological changes, coupled with the modulation of key genes involved in proliferation and apoptosis, suggest that leek water extract may have therapeutic implications in managing oral cancer.

Abstract

The utilization of intrusion detection systems (IDS) can significantly enhance the security of IT infrastructure. Machine learning (ML) methods have emerged as a promising approach to improving the capabilities of IDS. The primary objective of an IDS is to detect various types of malicious intrusions with a high detection rate while minimizing false alarms, surpassing the capabilities of a firewall. However, developing an IDS for IOT poses substantial challenges due to the massive volume of data that needs to be processed. To address this, an optimal approach is required to improve the accuracy of data containing numerous attacks. In this study, we propose a novel IDS model that employs the Random Forest, Decision Tree, and Logistic Regression algorithms using a specialized ML technique known as Ensemble Learning. For this research, we used the BoT-IoT datasets as inputs for the IDS model to distinguish between malicious and benign network traffic. To determine the best model, we compared the performance metrics of each algorithm across different parameter combinations. The research findings demonstrate exceptional performance, with metric scores exceeding 99.995% for all parameter combinations. Based on these conclusive results, we deduce that the proposed model achieves remarkable success and outperforms other traditional ML-based IDS models in terms of performance metrics. These outcomes highlight the potential of our novel IDS model to enhance the security posture of IoT-based systems significantly.

Abstract

The Air Quality Index (AQI) is a metric for evaluating air quality in a region. Jakarta holds the fifth position globally in terms of air pollution. Several studies have been performed to forecast pollution levels in Jakarta. However, existing studies exhibit limitations such as outdated datasets, lack of data normalization, absence of machine learning parameter setting, neglect of k-fold cross-validation, and a failure to incorporate deep learning algorithms for pollution detection. This study introduces an air quality detection system called APD-BayTM to address these issues. This proposed system leverages Long Short-Term Memory (LSTM) and uses Bayesian Optimization (BO) to enhance the performance of air pollution detection. The methodology used in this research involves four key steps: data preprocessing, LSTM model development, hyperparameter tuning through BO, and performance assessment using 5-fold cross-validation. APD-BayTM exhibits robust performance that is comparable to previous research outcomes. The LSTM model in APD-BayTM on the training dataset achieved average precision, recall, F1 score, and accuracy values of 93.29%, 91.41%, 91.89%, and 95.90%, respectively. These metrics improved on the test dataset, reaching 97.44%, 99.71%, 98.52%, and 99.34%, respectively. These findings show the robustness of APD-BayTM across datasets of varying sizes, encompassing both large and small datasets.

Abstract

This deep learning-based classification model was developed to recognize different types of pest infections in strawberry plants. The model aims to quickly identify pest symptoms, thus enabling efficient pest management in smart farming. This research uses an actual dataset containing images of strawberry leaves collected from smart farm trials. To expand the dataset, open data from platforms such as Kaggle were used, while images of infected leaves were obtained through web crawling with the help of Python libraries. The added data were converted to a uniform size, and PseudoLabeling was used to ensure stable learning on both training and testing datasets. The RegNet and EfficientNet models are selected as the main CNN-based models for iterative learning, with ensemble learning techniques to improve prediction accuracy. The proposed model aims to assist the early identification and treatment of pests on strawberry leaves during the early planting period, a crucial phase in the development of smart agriculture. It is hoped that this model can increase production in the agricultural industry and strengthen its competitiveness. Detecting early symptoms of plant diseases and pests is essential to prevent their development and minimize the damage caused. Although many methods have been developed using deep learning techniques, detecting early symptoms is still challenging due to the lack of datasets capable of training models against subtle changes in plants. Therefore, researchers built an automated data collection system to gather a large dataset of plant images and train ensemble models to detect diseases and pests of the target plants.

Abstract

This community service program aims to develop a monitoring system for toddler growth and development through Digital KMS in Lebakwangi Village, Arjasari District, Bandung Regency, by integrating digital technology, improving digital literacy, encouraging active community participation, and utilizing local potential. This program is designed as a response to the limitations of the manual recording system that has been used so far, which often causes data input errors, delays in monitoring, and difficulties in early detection of growth disorders and nutritional problems in toddlers. Through an integrated approach, the activity began with the development of a Digital KMS system that included in-depth needs analysis with all stakeholders—from posyandu cadres and health workers to parents—to identify the constraints of traditional recording and determine the main features that must be included, such as automatic data input, notifications, and an interactive forum dashboard that displays data in real time. The stages of system development include needs analysis, user-friendly interface design, development of reporting and analytics modules, pilot testing in several strategic posyandu, and full implementation integrated with the local health system. This digital KMS application was built using Laravel tools for the backend and React for the frontend. Furthermore, the program improves digital literacy through workshops and technical training held at health centers and facilities, the creation of educational modules in the form of video tutorials, written guides, and interactive materials, as well as ongoing assistance with the formation of a technical support team that is ready to provide assistance in the field. A participatory approach is implemented through community discussion forums and the involvement of community leaders as agents of change to optimize system usage, enhance a sense of ownership, and empower the community to actively participate in system evaluation and improvement. In addition, data-based monitoring and evaluation are carried out by activating interactive dashboards for periodic monitoring, data collection and analysis for early risk identification, and periodic evaluation through surveys and questionnaires to compile evaluation reports as a basis for system improvement. Synergy among partners, involving local governments, educational institutions such as Telkom University, and local communities, strengthens the ecosystem supporting this program through strategic collaboration that ensures policy support, material development, and ongoing assistance. By utilizing existing geographical and infrastructure potential as well as the cultural value of mutual cooperation, this program has successfully implemented and socialized a digital KMS application that is expected to not only improve the accuracy and effectiveness of health monitoring for toddlers, but also empower the community through increased digital literacy and sustainable digital transformation, thereby generating a long-term positive impact on the quality of health services and the quality of life of children in Lebakwangi Village.

Abstract

Arrhythmia refers to an irregular heart rhythm resulting from disruptions in the heart's electrical activity. To identify arrhythmias, an electrocardiogram (ECG) is commonly employed, as it can record the heart's electrical signals. However, ECGs may encounter interference from sources like electromagnetic waves and electrode motion. Several researchers have investigated the denoising of electrocardiogram signals for arrhythmia detection using deep autoencoder models. Unfortunately, these studies have yielded suboptimal results, indicated by low Signal-to-Noise Ratio (SNR) values and relatively large Root Mean Square Error (RMSE). This study addresses these limitations by proposing the utilization of a Deep LSTM Autoencoder to effectively denoise ECG signals for arrhythmia detection. The model's denoising performance is evaluated based on achieved SNR and RMSE values. The results of the denoising evaluations using the Deep LSTM Autoencoder on the AFDB dataset show SNR and RMSE values of 56.16 and 0.00037, respectively. Meanwhile, for the MITDB dataset, the corresponding values are 65.22 and 0.00018. These findings demonstrate significant improvement compared to previous research. However, it's important to note a limitation in this study—the restricted availability of arrhythmia datasets from MITDB and AFDB. Future researchers are encouraged to explore and acquire a more extensive collection of arrhythmia data to further enhance denoising performance.
