Abstract

Pratima is a sacred symbol in Balinese Hindu belief, holding high spiritual value and serving as a medium of worship in temples (pura). The increasing number of pratima thefts has caused not only material losses but also immaterial impacts due to the loss of their sanctity. This activity aims to develop and implement an intelligent system based on Radio Frequency Identification (RFID) and image detection technology for real-time monitoring and tracking of pratima in Desa Adat Bebalang, Bangli Regency. The system integrates long-range RFID with the Centroid Localization Algorithm and AI-based smart CCTV (VGG16), which can detect suspicious activity and automatically send notifications to the mobile application used by traditional security personnel. The program includes site mapping, equipment installation, training, trial implementation, and participatory evaluation with local communities and the Bendesa Adat. The results show that the system operates reliably, accurately, and is user-friendly. Evaluation data indicate that most respondents agreed or strongly agreed with the system’s usefulness. The system is technically effective and culturally accepted, with potential for replication in other temples across Bali. This initiative demonstrates that the integration of modern technology and local wisdom can offer sustainable solutions for the preservation and protection of cultural heritage.

Abstract

One of the main commodities that Indonesia exports is tuna. Indonesia's inadequate handling of food safety is demonstrated by a number of instances when the United States has rejected Indonesian fishery goods and food poisoning incidences. Fish quality grade is currently determined by manual inspection which has risk human mistake. According to Robert DiGregorio, four tuna grade classifications exist: grade 1, 2+, 2, and 3. The purpose of this study is to assess the tuna meat's quality according to its color. The procedure involves pre-processing images, training datasets, and classifying them using the Convolutional Neural Network (CNN) and k-Nearest Neighbors algorithms. CNN pre-processing involves converting the image into HSV color space and training the CNN model using 240 training datasets and 74 testing datasets. CNN’s accuracy was 84% higher than k-Nearest Neighbors' which was 54%. Additionally, a comparison of the classification accuracy of CNN, VGG (Visual Geometry Group) 16, and AlexNet revealed that CNN outperformed the others with an accuracy of 84%, followed by VGG16 with 70% and AlexNet with 66%.

Abstract

Efforts to preserve Balinese culture can be carried out by integrating art and technology as new steps that need to be developed. This research is motivated by the existence of various forms of God statues which have a central role in Balinese culture. The Deep Learning method is proposed because it has unique features that can be extracted automatically. The technique used in Deep Learning is Convolutional Neural Network (CNN). The training process is first performed to perform the classification process, and then the testing process is performed. We compared our CNN model with two other models, AlexNet and ResNet, based on the experimental results. Using a data split of 70%- 30%, our CNN model has the highest accuracy in managing statue image data. Specifically, our model achieves 97.14% accuracy, while Alexnet and Resnet achieve 24.44% and 33.33%, respectively. Apart from contributing to introducing the Balinese God Statue, this research can also be a basis for developing more comprehensive applications in culture and tourism.

Abstract

The increasing amount of internet content makes it difficult for users to find information using the search function. This problem is overcome by classifying news based on its context to avoid material that has many interpretations. This research combines the Uncased model BiDirectional Encoder Representations from Transformer (BERT) with other models to create a text classification model. Long Short-Term Memory (LSTM) architecture trains a model to categorize news articles about traffic violations. Data was collected through the crawling method from the online media application API through unmodified and modified datasets. The BERT Uncased-LSTM model with the best hyperparameter combination scenario of batch size 16, learning rate 2e-5, and average pooling obtained Precision, Recall, and F1 values of 97.25%, 96.90%, and 98.10%, respectively. The research results show that the test value on the unmodified dataset is higher than on the modified dataset because the selection of words that have high information value in the modified dataset makes it difficult for the model to understand the context in text classification.

Abstract

Electroencephalogram (EEG) is a non-invasive technology widely used to record the brain's electrical activity. However, noise often contaminates the EEG signal, including ocular artifacts and muscle activity, which can interfere with accurate analysis and interpretation. This research aims to improve the quality of EEG signals related to concentration by comparing the effectiveness of two denoising methods: Independent Component Analysis (ICA) and Principal Component Analysis (PCA). Using commercial EEG headsets, this study recorded Alpha, Beta, Delta, and Theta signals from 20 participants while they performed tasks that required concentration. The effectiveness of the denoising technique is evaluated by focusing on changes in standard deviation and calculating the Percentage Residual Difference (PRD) value of the EEG signal before and after denoising. The results show that ICA provides better denoising performance than PCA, as reflected by a significant reduction in standard deviation and a lower PRD value. These results indicate that the ICA method can effectively reduce noise and preserve important information from the original signal.

Abstract

An intrusion detection system (IDS) is a security technology designed to identify and monitor suspicious activity in a computer network or system and detect potential attacks or security breaches. The importance of accuracy in IDS must be addressed, given that the response to any alert or activity generated by the system must be precise and measurable. However, achieving high accuracy in IDS requires a process that takes work. The complex network environment and the diversity of attacks led to significant challenges in developing IDS. The application of algorithms and optimization techniques needs to be considered to improve the accuracy of IDS. Support vector machine (SVM) is one data mining method with a high accuracy level in classifying network data packet patterns. A feature selection stage is needed for an optimal classification process, which can also be applied to SVM. Feature selection is an essential step in the data preprocessing phase; optimization of data input can improve the performance of the SVM algorithm, so this study compares the performance between feature selection algorithms, namely Information Gain Ratio and Chi-Square, and then classifies IDS data using the SVM algorithm. This outcome implies the importance of selecting the right features to develop an effective IDS.

Abstract

Manual attendance systems in health clinics are often ineffective, reducing service quality, and increasing operational costs. This study designed an integrated digital attendance system with a mobile application for medical personnel and an admin website aimed at improving the efficiency and accuracy of attendance management. Development followed the Waterfall SDLC model, while testing included Black-Box Testing, Cognitive Walkthrough (CW), and System Usability Scale (SUS). The mobile application supports in-clinic/out-of-clinic attendance (Wi-Fi validation, geolocation, selfie photos, documents), leave requests, work schedules, attendance recaps, and pay slips. The admin website facilitates employee data management, attendance and leave validation, work schedule creation, and salary and attendance recaps. Black-Box Testing results showed success in all functional scenarios; CW recorded 96% effectiveness (mobile) and 98% (website) with very fast efficiency; SUS scores of 76.42 and 76.07, respectively, indicating good usability; and API testing proved smooth data integration. This system has been proven to be functional, effective, efficient, and ready to be implemented in health clinics.

Abstract

Sealed Lead Acid (SLA) batteries are prone to damage caused by overcharging and overheating during the charging process. To address this issue, this study aims to design and develop an Internet of Things (IoT)-based monitoring system integrated with a mobile application to wirelessly monitor the charging of two SLA batteries, as well as prevent overheating and overcharging. The system employs the INA219 sensor to measure voltage and current, and the DS18B20 sensor to measure temperature. Current, temperature, and voltage data are transmitted to Firebase using an ESP32 microcontroller and displayed on an Android application called MySyM, developed with Android Studio. This research successfully realizes a functional, accurate, and effective IoT-based monitoring system to enhance the safety of SLA battery charging. The analysis of test results for the INA219 and DS18B20 sensors shows a Mean Absolute Error (MAE) of 0.24995 V for voltage and 2.1068 °C for temperature on the 12 V battery, as well as 0.1299 V for voltage and 1.3295 °C for temperature on the 6 V battery, demonstrating high measurement accuracy.

Abstract

This study aims to analyze the effect of Good Corporate Governance (GCG) mechanisms, represented by the board of commissioners, board of directors, and audit committee, on financial performance, as well as to examine the role of company size as a moderating variable. This is a quantitative study using secondary data from transportation and logistics companies listed on the Indonesia Stock Exchange for the period 2019-2024. The study population consisted of 38 companies, with a sample of 138 observations determined using purposive sampling techniques. Data analysis was performed using multiple linear regression and MRA. The results show that the board of directors has a positive and significant influence on financial performance. Meanwhile, the board of commissioners and audit committee have no direct influence. The moderation test shows that company size can strengthen the influence of the board of commissioners and audit committee on financial performance, but does not moderate the relationship between the board of directors and financial performance.
