Utilization of Spiking Neural Network (SNN) in X-Ray Image for Lung Disease Detection
Get PDFThe large number of cases of lung disease means that doctors have difficulty in making initial diagnoses, making them prone to misdiagnoses. One type of lung disease that is included in the vulnerable category is pneumonia. Early detection of the condition of the lungs affected by bacterial pneumonia can be carried out by screening using the X-Ray examination modality, namely Digital Radiography (DR). However, in practice, the diagnosis process on Citra DR takes a long time because it requires competent medical personnel (specialists). A system is needed that can help medical personnel to speed up the process of diagnosing lung disease and get accurate results so that misdiagnosis does not occur. The aim of this research is to utilize the Spiking Neural Network (SNN) method for classifying lung disease from DR images. The system was created using MATLAB with the initial step of creating a read data program, namely reading DR image secondary data in .jpg format taken from Kaggle.com. This research uses DR image data totaling 200 images. Next, standardize the size to 50 x 50 pixels. Then segmenting the image divides the gray level histogram into two different parts of the image automatically without requiring user assistance to enter threshold values for normal and pneumonia images. Then convert the image to 1 dimension and create a manual program for the training data using 50 normal images and 50 pneumonia images. Lastly, create a program to test the data using 100 normal images and 100 pneumonia images. Based on the results of data testing, a confusion matrix was obtained from 200 images with sensitivity of 87%, specificity of 69%, precision of 73.7288%, recall of 69%, and accuracy of 78
Analysis of Power Quality in Low Voltage Switch Panels in Real-Time Based on IoT Using the Fuzzy Logic Method
Get PDFThis far power quality analysis from the PHBTR monitoring system is still done manually. This condition creates several challenges in efficiency and accuracy in detecting and responding to changes in PHBTR power quality. With manual processes, collecting and analyzing data related to power quality can be time consuming, and there is the potential for delays in identifying disturbances or anomalies that could affect PHBTR performance. Therefore, in this research an innovative step was taken by applying the fuzzy logic method to simplify and increase the accuracy of automatic power quality analysis. From the analysis results, it was found that the power quality at the MCC4, GRL2, and CKG116 substations when viewed from voltage, current, frequency, and temperature, the three substations were at normal indications (91.32) and in good condition (76.32). However, the load balance quality of the three substations is still not balanced with load imbalance percentages of 110%, 52% and 17% respectively. This is because there are consumers in one phase using higher power than consumers in another phase, so a load imbalance will occur. This can be caused by differences in the use of electrical equipment or loads on each phase. Through this effort, it is hoped that significant improvements in the efficiency and responsibility of the PHBTR monitoring system can be achieve

The Barriers of Using Video Games as a Media for Teaching and Learning Purposes: A Case Study in Indonesia
Get PDFThe 21st century has seen the remarkable growth of the video game industry, which has surpassed other entertainment sectors in terms of financial value. The COVID-19 pandemic further emphasized the importance of video games as a means of socialization and entertainment. However, despite their potential in education, the adoption of video games as a learning media faces numerous barriers. This study explores these barriers, particularly in the context of Indonesia, a country with a burgeoning video game culture. The research uses a mixed-methods approach, including qualitative interviews and quantitative surveys with stakeholders such as parents, teachers, students, and government officials. The findings reveal several key barriers to adopting video games in formal education in Indonesia. There is an inherent mistrust of video games among Indonesians, which makes the use of video games as a learning media challenging. There is a lack of video games designed for educational purposes suitable for Indonesia's formal education system. The lack of government support for video games as learning media also becomes an issue. We suggest collaboration between local game developers and education practitioners could help design video games that balance gameplay mechanics and educational content. Successful case studies of video games in education can potentially change negative perceptions among teachers, parents, and students. In addition, government support and recognition of video games as valid learning media are essential for wider adoption in Indonesia's formal education system. Future research should focus on developing and adopting video games specifically designed for educational purposes to address these barriers effectivel
