Abstract

The increasing demand for sustainable electricity requires hybrid renewable energy systems capable of improving power supply reliability and operational supervision under variable energy-source conditions. Purpose: This study aims to design and implement a laboratory-scale hybrid renewable energy control system integrating an Archimedes screw turbine and a photovoltaic system with PLC-based control and SCADA monitoring. Methodology: An experimental design and implementation approach was employed by integrating renewable energy generation, battery storage, electrical measurement devices, an industrial PLC, HMI, and cloud-based SCADA platform. Electrical voltage, current, power, energy, battery condition, and load status were acquired during laboratory testing and evaluated based on the functionality of monitoring, data logging, trend visualization, alarm notification, battery protection, and load control. Findings: The developed system successfully integrated renewable energy generation and industrial automation into a unified supervisory platform. The PLC continuously acquired electrical parameters, executed battery protection and load-switching logic, and communicated with the HMI and SCADA system. Real-time monitoring, historical data recording, graphical trend visualization, alarm notification, and remote load control operated successfully during experimental testing. Implications: The proposed architecture provides a practical platform for renewable energy monitoring, industrial automation education, and further development of automatic energy management and predictive supervision systems. Originality: Unlike previous studies that primarily focus on photovoltaic performance, Archimedes screw turbine optimization, or SCADA architecture separately, this study integrates photovoltaic generation, an Archimedes screw turbine, battery storage, industrial PLC control, HMI visualization, and cloud-based SCADA monitoring within a single laboratory-scale hybrid renewable energy platform.

Abstract

Coil-on-plug (COP) ignition faults can involve the coil, connector, harness, and electronic control unit (ECU), yet a single workshop case cannot establish the initiating component or transient chronology. This evidence-classified diagnostic case examined one Daihatsu Xenia 1.0 Non-VVT-i with an EJ-DE three-cylinder gasoline engine presenting vibration, misfire, reported loss of power, and reported increased fuel consumption. The available field record documented visual inspection, multimeter observations of supply and ignition trigger/feedback (IGT/IGF) lines, coil substitution, guarded substitution with a known-good ECU, on-board diagnostics II (OBD-II) scanning, internal ECU and connector inspection, corrective repair, and preliminary workshop verification. The multimeter did not detect comparable IGT/IGF indications on cylinders 2 and 3; replacing the suspected coils did not resolve the symptoms; and the donor ECU displayed diagnostic trouble codes (DTCs) P0300, P0352, P0353, and P0171. Degraded female connector contacts and visible damage along the original ECU ignition-driver path were subsequently observed. Repair of the documented defects was followed by restored continuity and stable operation during an unspecified workshop observation period. The evidence supports system-level diagnosis of an interconnected coil-connector-ECU fault, but not a proven cascade from coil switching to ECU damage. The principal contribution is a transparent reporting framework that separates direct observation, diagnostically supported interpretation, and unmeasured mechanism. The case also provides a safety-conscious diagnostic sequence for workshop and proposed vocational-learning use.

Abstract

This study designed and implemented a prototype paddy-husk separator that integrates a 200 Wp off-grid photovoltaic (PV) power system with vibrating-sieve and pneumatic separation. The mechanical assembly uses a hollow-steel frame, a perforated sieve, an eccentric drive, and a fan, while the electrical subsystem comprises a solar panel, a solar charge controller, a 12 V battery, and a 1000 W inverter. Prototype tests were reported at input loads of 10, 15, and 20 kg. The measured AC load remained at 126-132 W, which is below the inverter power rating. The pulley ratio of a 50 mm motor pulley and a 12-inch driven pulley yields a calculated sieve-shaft speed of 196.85 rpm, compared with a 214 rpm design target. Under the reported test conditions, the highest observed processing capacity was 723 kg/h at a 15 kg input load, whereas the highest reported separation efficiency (86.2%) and the lowest reported loss (1.50%) occurred at 20 kg. These results demonstrate the feasibility of integrating off-grid PV power with dual mechanical-pneumatic separation at prototype scale. However, the study does not document paddy variety, moisture content, replicate-level variability, or the full mass-balance record used to reconstruct separation efficiency and losses; therefore, field reliability, solar autonomy, and broader performance claims require further validation.

Abstract

This study aims to evaluate the responsiveness of the MAX6675 sensor regarding motor movement within an Arduino Uno-based Conveyor system. Testing was conducted to assess the sensor's ability to detect temperature changes and to observe the motor control system's response based on the measured temperature. The MAX6675 sensor served as the interface module for a K-type thermocouple, while the Arduino Uno acted as the central controller and a DC motor functioned as the Conveyor actuator. Temperature readings were displayed on an LCD, allowing for the observation of temperature fluctuations during the testing process. The methodology involved subjecting the K-type thermocouple to incremental temperature changes and monitoring the DC motor's response to the temperature values ​​read by the MAX6675. Data collected included temperature values, motor status, sensor response time, and the time required for the motor to start or stop once the temperature reached a predetermined threshold. Tests were performed across various temperature limits to determine the system's responsiveness to temperature changes. The results demonstrate that the MAX6675 sensor effectively reads temperature changes from the K-type thermocouple and transmits data to the Arduino Uno to govern DC motor control. When the temperature remains below the set limit, the motor operates; conversely, when the temperature reaches the programmed limit, the Arduino signals the motor driver to halt the motor. Thus, this evaluation of MAX6675 sensor responsiveness establishes the relationship between detected temperature changes and motor movement within the Conveyor system.

Abstract

Turbin ulir Archimedes menjadi solusi populer dalam pembangkit listrik mikrohidro berkat desainnya yang sederhana dan ketahanan pada kondisi head rendah. Berbagai studi telah membuktikan bahwa efisiensi daya turbin ini sangat dipengaruhi oleh sudut kemiringan porosnya. Namun, metode penyetelan manual yang selama ini digunakan oleh operator sering kali tidak praktis, menguras tenaga, dan lambat dalam merespons kebutuhan perubahan sudut yang berulang. Penelitian ini menjawab tantangan tersebut dengan mengembangkan sistem kendali elektrik berbasis Arduino Uno dan aktuator linear. Perangkat ini dirancang secara sinergis menggunakan potensiometer sebagai input sudut, modul relay dua saluran sebagai pengontrol arah, serta aktuator 12V DC sebagai penggerak mekanis. Secara operasional, Arduino membaca sinyal analog dari potensiometer untuk dibandingkan dengan nilai acuan (setpoin). Perbedaan nilai tersebut akan secara otomatis memicu aktuator untuk bergerak maju dan mundur sehingga posisi ulir yang diinginkan tercapai. Dengan sistem ini, operator dapat mengubah kemiringan turbin secara presisi hanya melalui putaran potensiometer. Hasil uji menunjukkan bahwa sistem ini mampu mengesekusi perintah dengan respons yang cepat. Implementasi teknologi ini berhasil mengubah proses pengaturan sudut yang tadinya berat dan mekanis menjadi lebih praktis serta efisien, sekaligus menghilangkan kebutuhan akan intervensi fisik langsung dari operator di area turbin.

Abstract

Background and Objective: Vocational engineering education requires authentic projects that connect design, fabrication, measurement, testing, and evidence-based improvement, yet technical machine studies are rarely organized as reusable educational cases. This study evaluated a compact low-power grass chopping machine and examined its suitability as an authentic project case for vocational engineering education. Methods: An experimental engineering design was conducted from February to August 2026 using a FLASH-250G 1/4-HP motor, one 1.6-mm steel-plate blade, and a compact steel frame. Elephant, odot, and sansibar grass were tested at 1-5 kg loads. Rotational speed, chopping time, and post-chopping mass were recorded, and three test series were averaged for each condition; analysis was descriptive because run-level dispersion data were unavailable. Results: The machine completed all reported conditions at 2,457-2,978 rpm. Chopping time increased from approximately 2-3 minutes at 1 kg to approximately 10 minutes at 5 kg, with descriptive load-time slopes of 116.28-121.41 seconds/kg. Derived batch processing rates were approximately 22.49-29.37 kg/h. Conclusion: The prototype demonstrates functional feasibility under the reported conditions and provides a technically grounded authentic-project structure for vocational engineering learning in design, fabrication, measurement, safety, data interpretation, and redesign. Educational effectiveness was not tested and requires direct student-outcome evidence.
