Abstract

In this study, we present the development and implementation of a low-cost IoT wearable device, the Smart Ring, designed to monitor body fatigue levels. Fatigue, often resulting from energy-draining physical activities, can lead to serious health conditions such as heart attacks, strokes, and asthma. Current devices like smartwatches offer limited functionality in preventing fatigue by merely providing vital sign information. Our Smart Ring aims to bridge this gap by integrating advanced sensors (MAX30100 for heart rate, SpO2, and body temperature) and utilizing fuzzy logic for real-time fatigue level classification. The Smart Ring is paired with an Android application that not only tracks the user's physiological data but also issues alerts and notifications when fatigue thresholds are reached, ensuring timely intervention. The device is designed to be economical and accessible, promoting widespread adoption for better health monitoring in the Society 5.0 era. Preliminary testing with users has demonstrated the effectiveness of the Smart Ring in accurately detecting and categorizing fatigue levels during various activities, supporting its potential as a valuable tool in personal health management.

Abstract

Streetlight systems generally use time condition as the parameter, which set the lights to be always on during specified period. This way, the system has flaws in its inefficiency and ineffectiveness. The system designed in this research considers the intensity of surrounding lights and passing pedestrians as the parameters, and fuzzy logic to get fuzzier output of the luminosity level for the streetlight. From the results of testing and analysis, it can be concluded that the design in this research has been successfully built as the results obtained are in accordance with the previously set fuzzy logic universe of discourse. By implementing an adaptive street lighting system in this study can help streamline light energy, because the street lighting lights can adjust themselves depending on the presence or absence of pedestrians passing by using a PIR sensor and the level of light brightness in that place using an LDR sensor.

Abstract

Network-Attached Storage (NAS) based on low cost Single Board Computers (SBC) offers an affordable alternative to commercial storage systems, yet its exposure to network-based threats requires a robust and layered security approach. This research implements the Defense-in-Depth (DiD) framework on an Orange Pi based NAS running Debian 12, integrating host-based security mechanisms and the ZFS file system to enhance data integrity, availability, and system resilience. The security layers include firewall restrictions, intrusion prevention with Fail2Ban, integrity monitoring using AIDE and rkhunter, system auditing with Lynis, and log analysis with Logwatch. Additionally, ZFS snapshots and the Sanoid retention policy are applied to provide rapid data recovery with minimal storage overhead. Experimental results show that all defense layers function effectively under testing scenarios such as brute-force attempts, unauthorized port access, file modification, and data deletion. ZFS snapshots successfully restore deleted or altered files, ensuring minimal Recovery Point Objective (RPO) of one hour. System performance remained stable, with CPU usage averaging only 7.9% and memory usage at 33%, indicating that the DiD model is feasible even on low-resource SBC hardware. These findings demonstrate that a cost-efficient SBC-based NAS can achieve strong resilience against common cyber threats through layered security design and modern file system capabilities.
