Abstract

Drowsiness-related traffic accidents are one of the leading causes of road fatalities. Drowsiness reduces concentration and slows a driver’s reaction time to road conditions. This research aims to design and implement a drowsiness detection system based on the Raspberry Pi 4 Model B+, capable of providing early warnings through an audible alarm and sending notifications to an administrator via email. The system employs a web camera to capture real-time facial images of the driver, which are then processed using the Eye Aspect Ratio (EAR) method with the OpenCV and Dlib libraries. If the EAR value falls below a predefined threshold for a certain duration, the system triggers a speaker alarm and sends notifications to the administrator. The system was tested under various lighting and distance conditions to evaluate its accuracy. The results show that the system can detect drowsy eye conditions with an accuracy good. This system is expected to serve as a preventive solution to reduce the risk of accidents caused by drowsiness, particularly for both private and commercial vehicle drivers.

Abstract

The transition from analog to digital television broadcasting in Indonesia improves picture and sound quality; however, signal reception in rural areas remains a challenge due to long distances from transmitters and unfavorable topography. Conventional antennas and signal boosters have not provided optimal performance. This study aims to design a vertical linear antenna array with a stacking configuration to enhance digital television signal reception in the Ultra High Frequency (UHF) band. The antenna design was carried out through theoretical calculations, simulation, and optimization using CST Studio Suite 2019. The analyzed parameters include return loss, VSWR, gain, bandwidth, and radiation pattern. Simulation and testing results show that the antenna achieves a return loss below −10 dB, VSWR less than 2, gain above 10 dBi, and a unidirectional radiation pattern. The proposed antenna effectively improves digital television reception quality in rural areas.

Abstract

Automatic Dependent Surveillance-Broadcast (ADS-B) allows real-time monitoring of aircraft positions, but Software Defined Radio (SDR) devices such as the RTL-SDR have sensitivity limitations that can affect signal reception quality, especially at long distances or under less than ideal  conditions. This study designs an ADS-B receiver system based on the RTL-SDR equipped with a Low Noise Amplifier (LNA) to amplify weak signals without adding significant noise. The method includes receiver circuit design, antenna installation, LNA integration, and signal reception testing at various distances. Reception data with and without the LNA are compared based on the maximum distance and the number of messages received. The results show that the LNA increases the maximum reception distance from 309.95 km to 417.90 km and improves signal stability at medium and short distances. This system is able to capture more messages, including from aircraft under less than  ideal  propagation  conditions. The combination of the RTL-SDR and LNA has proven to be effective and economical as an alternative to expensive device-based flight monitoring.

Abstract

Used motorcycle prices in the market often fluctuate and are influenced by various factors such as brand, type, year of manufacture, engine capacity, mileage, vehicle condition, and tax status. In Kupang City, the determination of used motorcycle prices is generally still performed manually based on seller estimates or market conditions, which can lead to significant price differences. Therefore, a method is needed to estimate used motorcycle prices more objectively and accurately. This research seeks to develop a model for predicting used motorcycle prices employing the Random Forest algorithm. The dataset used consists of 200 used motorcycle records collected from used motorcycle sales data in Kupang City. The data undergoes a preprocessing stage before being used for model development. Furthermore, the dataset is partitioned into training data and testing to build evaluate prediction. The evaluation results show a Mean Absolute Error (MAE) of Rp.4,418,477, a Mean Squared Error (MSE) of 26,617,157,710,315, and a Root Mean SquSquared Error (RMSE) of Rp.5,159,181. The findings suggest that the Random Forest predict motorcycle prices with reasonably acceptable error rate, making it a useful approach for estimating used motorcycle prices based on vehicle attributes.

Abstract

The rapid growth of mobile data traffic in cellular networks has created significant challenges in maintaining network performance, particularly during peak usage periods known as busy hour. During these periods, high user density leads to increased traffic load, resulting in network congestion and degradation of key performance indicators such as throughput, latency, jitter, and packet loss. This study aims to analyze conceptually the impact of busy hour traffic on cellular network performance through a structured literature review approach. The method involves collecting and synthesizing recent studies from reputable journals to identify patterns and relationships between traffic load and network performance parameters. The results indicate that increased traffic during busy hour consistently causes resource contention, leading to decreased throughput and increased latency, jitter, and packet loss. Furthermore, this study reveals that most existing research is empirical and case-specific, lacking an integrated conceptual framework. Therefore, this research contributes by providing a comprehensive conceptual understanding of the causal relationship between busy hour traffic and cellular network performance degradation, which can support future research and network optimization strategies.

Abstract

The rapid development of 4G LTE technology is often challenged by dynamic traffic patterns, particularly in tourist areas like Bungus Teluk Kabung, Padang. This research aims to analyze and compare the Quality of Service (QoS) of Telkomsel's 4G LTE network during weekday and weekend periods. Data collection was conducted using the drive test method with TEMS Pocket 2 software in dedicated mode to measure key parameters: RSRP, RSRQ, SINR, and throughput. The results indicate a significant difference in network performance between the two periods. While signal coverage (RSRP) remained stable and "Good" (above 55%) in both timeframes, throughput experienced a sharp degradation during weekends. On weekdays, 61.5% of samples were in the "Good" throughput category, whereas on weekends, "Poor" samples (< 512 kbps) surged to 34.94%. This decline is strongly correlated with increased interference and network congestion caused by the surge of users in tourist spots. The study concludes that network issues are driven by capacity limitations rather than coverage, requiring infrastructure optimization to handle peak weekend loads.

Abstract

Rapid advancements in information technology have increased the use of digital systems across various sectors, including business, education, and government. While information systems offer convenience in data management and operational efficiency, they also introduce new risks related to information security and data protection. This condition highlights that digital systems must not only be efficient but also capable of ensuring security and building user trust. This study aims to analyze the role of confidentiality, integrity, and availability as fundamental principles of information security, along with privacy and Terms and Conditions, in establishing digital trust within modern information systems. A qualitative approach was employed using a literature review method, where data were collected from relevant scientific journals and analyzed descriptively and analytically to identify relationships among key concepts. The findings indicate that security principles provide a strong technical foundation but are not sufficient to address challenges related to human behavior. Privacy plays a crucial role in protecting users’ personal data, while Terms and Conditions contribute to transparency in digital service management. The integration of these aspects demonstrates a strong interconnection in building digital trust. This study emphasizes the importance of a comprehensive approach to enhancing user trust and provides insights for improving the reliability of digital systems in organizational contexts.
