Abstract

This research developed and tested an Internet-of-Things-based off-grid solar power plant monitoring system on mobile towers using the Telegram platform as the monitoring medium. The objective of this research was to create an efficient and real-time mobile tower performance monitoring system based on temperature, current, power, light intensity, voltage, latency, and error percentage. The experimental method, using hardware (ESP32, RS485, LM2596) and software (Telegram) for data monitoring, was tested in the field. Testing was conducted twice on different dates, weather conditions, and for different durations. The results showed a system efficiency of 84.68%, error below 5%, accuracy of 99.54% for temperature, 98.52% for current, 98.7% for power, and 99.33% for voltage, with latency of 89-267 ms. The system was deemed to meet the criteria for a sustainable mobile tower monitoring solution.

Abstract

This research aims to develop and evaluate the performance of SCONER (Smart Cobweb Cleaner), an Internet of Things (IoT)-based cobweb cleaning tool for hard-to-reach areas. This tool is equipped with a 1–3 meter telescopic pole, a 2 MP ESP32 camera, an ILI9488 LCD screen for wireless monitoring, and a TP5100 module connected to Firebase for real-time battery monitoring. SCONER uses a 3000 mAh vacuum battery and a 6000 mAh camera battery with a total weight of approximately 1.3 kg, making it lightweight and easy to use. The research method includes system design and testing the tool's performance in cleaning cobwebs and dust. The test results show that SCONER is able to work effectively, facilitate the cleaning process in hard-to-reach areas, and supports real-time monitoring of power usage. This tool has the potential to be a practical solution for household cleaning needs and professional cleaning services.

Abstract

This study analyzes the relationship between Total Harmonic Distortion (THD) and electrical energy efficiency in medium-voltage distribution panels at PT Indonesia Chemical Alumina. Measurements were conducted using the ABB ANR96 power analyzer connected via RS485 communication and monitored using ABB SW01-128 software for seven days. The observed parameters include THDv, THDi, power factor (PF), and kW/kVA ratio. The results show that the average THDv in all panels is 0%, indicating voltage distortion within standard limits. THDi values vary across panels, with the highest value recorded at 3.60% and the lowest at 0%. The average PF ranges from 0.66 to 0.72, indicating moderate efficiency conditions. Correlation analysis shows a negative relationship between THDi and energy efficiency with a correlation coefficient of −0.2329 and a determination coefficient of 24.73%, categorized as low correlation. These findings indicate that although THDi values are relatively small, they still directly influence energy efficiency in medium-voltage distribution systems.

Abstract

This study discusses a hot airdrying system for Robusta coffee cherries from Gombengsari, addressing issues that disrupt traditional sun-drying processes, such as unpredictable rainfall, vulnerability to pests, and overnight storage that causes reabsorption of moisture in the dried coffee. An experimental method was employed to determine the optimal drying temperature for coffee cherries that preserves their characteristics and flavor profile. Comparative results from the hot air-drying system for Robusta coffee cherries showed moisture content reductions of 25.2%, 30.27%, 37.37%, 25.10%, 30%, and 37%. The application of hot air drying influenced the final weight, moisture content levels, and average error rate of 1%. Drying was conducted over 5 hours with initial coffee weights of 300g and 500g, at temperatures starting from 45°C. For 300g batches: 45°C yielded 25.2% moisture content, 55°C yielded 30.27%, and 65°C yielded 37.37%. For 500g batches: 45°C yielded 25.10% moisture content, 55°C yielded 30%, and 65°C yielded 37%. The optimal drying condition was achieved with a 300g batch at 65°C, resulting in 37.37% moisture content reduction and a final weight of 187.9 grams.

Abstract

This study aims to analyze traffic performance along the Gatot Subroto Road corridor and design a simulation-based adaptive traffic light control system using PTV VISSIM software. This data was then modeled in PTV VISSIM to evaluate traffic performance parameters, including average queue length, maximum queue length, vehicle delay, stop delay, and the number of vehicles stop. Simulation results indicate that the South-to-North approach on Gatot Subroto Road—leading toward Ketapang Port—experiences the highest density compared to other approaches. The average queue length reached 11.30 meters, with a maximum queue length of 210.41 meters. Additionally, the average vehicle delay was 38.01 seconds, and the stop delay was 6.25 seconds. These conditions highlight that the traffic flow toward the port area constitutes a critical point requiring more effective traffic management. Consequently, the implementation of an adaptive traffic light control system is expected to optimize signal timing based on real-time traffic conditions, thereby reducing vehicle queues and delays while improving overall traffic performance along this strategic corridor leading to Ketapang Port, Banyuwangi.
