Abstract

Almost every vehicle will need maintenance such as oil change, tire change, water radiator, brake, engine parts and much more. However, sometimes vehicle owners are less concerned with the condition of the vehicle and often ignore the treatment. This can be bad, it can even lead to an accident. Therefore, the monitoring system is designed to monitor the level of radiator water in vehicle tanks. The ultrasonic sensor will measure the water level of the radiator in the r eservoir tank. If the water level of the radiator in the tank is low then the pump will automatically recharge the radiator water and the buzzer will sound faster. The data from the ultrasonic sensor will be sent to the microcontroller with fuzzy logic. Ve hicle owners can access information in the form of water level radiator in the tank via wifi module and wifi router. So the problem of damage to the vehicle can be overcome quickly, easily, and efficiently.

Abstract

Current technological developments make security crucial in protecting important documents. Safes are commonly used for storage but remain vulnerable to burglary despite conventional locks. Based on data from the Central Bureau of Statistics (BPS) in 2023, aggravated theft was the most frequent crime with 62,872 reported cases. This highlights the need to improve safe security by adding biometric techniques such as face recognition and fingerprint verification. This study proposes a layered security system combining face recognition using the YOLO algorithm and fingerprint sensors. The system uses an ESP32-CAM to capture facial images and an ESP32 microcontroller to control a solenoid lock, fingerprint sensor and buzzer alarm. Face recognition testing on two users showed, the trained YOLO model achieved an accuracy of 83.33%, precision of 83,33% and recall of 100%.  from 12 trials, with two failures due to poor lighting conditions. Fingerprint testing on 10 samples, five fingers from each of two users, showed successful recognition of all fingerprints with an average response time of 1.41 seconds. The integration of face and fingerprint biometrics significantly enhances safe security and minimizes unauthorized access risks.

Abstract

The increasing dependence on web-centric digital document management for archiving contracts, academic credentials, and administrative records has intensified anxieties regarding data manipulation and unauthorized alterations. Traditional cryptographic verification methods, including MD5 and SHA-1, are no longer viable due to demonstrated collision vulnerabilities. Meanwhile, more robust alternatives like SHA-256 and SHA-3 frequently encounter performance bottlenecks when processing large volumes of data in real-time web architectures. To address these limitations, this research integrates BLAKE3 a cutting-edge cryptographic hash function that pairs SHA-256-level security with superior throughput via a parallelized Merkle-tree design into a web-based platform dedicated to document integrity verification. Adopting a Research and Development (R&D) methodology framework alongside the Waterfall System Development Life Cycle (SDLC), the project progressed through requirements analysis, system architecture design, deployment, and evaluation phases. The prototype was built using a PHP/Node.js web stack backed by a relational database that logs the BLAKE3 hash of each uploaded asset, recalculating and cross-checking the signatures upon every retrieval query. System performance was assessed via black-box functionality assessments, avalanche effect trials, and hash execution time benchmarks contrasting BLAKE3 against MD5, SHA-256, and SHA-3. The empirical data demonstrates that the platform achieved a 100% success rate in identifying simulated file tampering. Furthermore, BLAKE3 outpaced SHA-256 by a factor of 3.7 to 8.1 depending on file dimensions, while yielding an optimal avalanche effect of 49.9%. These outcomes suggest that BLAKE3 serves as a highly scalable and dependable substitute for safeguarding digital assets within web information systems, particularly for platforms handling high-throughput document verification.

Abstract

The growth of oyster mushrooms (Pleurotus ostreatus) is highly influenced by appropriate temperature and humidity conditions. However, the environmental conditions at the research site frequently exceeded the ideal range, and monitoring was still conducted manually, requiring the farm owner to visit the cultivation house directly to determine its environmental conditions. This study aimed to design and implement a temperature and humidity monitoring system using a DHT22 sensor with LoRa communication and Node-RED visualization, as well as to analyze the system performance based on data transmission success and its capability to display monitoring data in real time. The research employed experimental and observational methods, including system design, implementation, testing, and performance evaluation during operation. The system consisted of a DHT22 sensor, an Ebyte E220-900T22D LoRa module for data communication, an ESP32 Microcontroller, and Node-RED as the visualization platform. The results showed that the system successfully transmitted data over a distance of up to ±100 meters with average measurement errors of 2.52% for temperature and 2.56% for humidity compared with the reference instrument. Furthermore, the system displayed temperature, humidity, and RSSI values in real time and consistently monitored the cultivation environment for seven consecutive days. These results indicate that the proposed system is reliable as an accurate, efficient, and real-time monitoring solution for oyster mushroom cultivation.
