Abstract

Frequent and unpredictable weather changes present a particular challenge for laundry businesses, especially when it comes to drying clothes during the rainy season. It is not uncommon for clothes that are almost dry to get wet again from sudden rain showers. These conditions are undoubtedly inconvenient and consume a significant amount of time and effort. To address this issue, this study designed an automatic canopy control system based on the Internet of Things (IoT). This system can quickly detect weather changes and provide users with convenience. The goal is to simplify the drying process and protect clothes from getting wet, which impacts service quality and business productivity. The system uses a Raindrop sensor to detect rainwater and an LDR sensor to measure light levels. A NodeMCU ESP8266 serves as the control centre and is connected to the internet. The microcontroller processes all sensor data and sends it to the Blynk app. This allows users to monitor drying conditions in real time via their smartphone and manually control the canopy if necessary. Test results show that the system responds well to weather changes and functions as intended. It is hoped that, with this system in place, the process of drying clothes will become more practical, efficient, and convenient so users no longer need to worry about unpredictable weather.

Abstract

Dissolved oxygen (DO) levels are an important parameter in fish farming because they directly affect fish metabolism, growth, and survival. This study designed an automatic aeration system based on Proportional–Integral–Derivative (PID) control using a LilyGO T-Relay microcontroller and an AC Dimmer module. The system is equipped with DO, pH, and temperature sensors that monitor water quality in real-time and send data to Google Sheets via a Wi-Fi connection. Tests were conducted at four DO setpoints: 4 mg/L, 5.3 mg/L, 6 mg/L, and 7 mg/L. The results showed that the system was able to maintain DO with an average error of 2.02% and energy savings of up to 99.5%, with the lowest power consumption of 0.45 Wh at the 4 mg/L setpoint. This system is considered effective in maintaining water quality while increasing energy efficiency in fish farming.

This study aims to design the Microgreen Feed Machine (MICHINE), an automatic watering and monitoring system based on a local web server using ESP-32. A Research and Development (R&D) approach was employed with experimental testing to measure sensor performance and system accuracy. Results indicate that the RTC module successfully scheduled watering with high precision. The DHT22 sensor demonstrated an average temperature accuracy of 99.72% and humidity accuracy of 94.49%, while the ultrasonic sensor effectively detected harvest readiness with minimal error. The implementation of a local web server proved reliable in delivering real-time data without relying on external internet connections. The system significantly enhances operational efficiency by reducing manual intervention, making wheatgrass cultivation for qurban feed more economical and practical.

The robot can automatically move to predefined locations using GPS and azimuth calculations from a digital compass sensor. The pH sensor is inserted into the ground using a servo motor at a specific depth. Tests were conducted at several locations to evaluate navigation accuracy and insertion success. The results showed that the robot could reach target coordinates with a deviation of less than 13.5 cm, but the pH sensor insertion failed 100%. The navigation system worked well with stable motor RPM, and the wireless control functioned properly. In conclusion, the robot succeeded in navigation but failed in the automatic sensor insertion process.

Abstract

Ornamental fish farming at the partner-seller scale often faces operational efficiency challenges, particularly related to water quality management. Observations with partners revealed issues such as inefficient electricity costs and manual water drainage methods, which pose risks to fish health and increase workloads. This research aims to design an Internet of Things (IoT)-based water quality monitoring system to automate aquarium monitoring. The system uses an ESP32WROOM 32 microcontroller as the main processing unit, a turbidity sensor to detect water turbidity levels, and a water-resistant JSN-SR04T ultrasonic sensor to measure water levels. Test results showed that the turbidity sensor was able to operate with an average error rate of 11.56%. Meanwhile, the JSN-SR04T sensor demonstrated a very high level of accuracy, with a precision of ± 0.2 cm. In terms of connectivity, analysis of data transmission to the IoT platform demonstrated stable performance with an average latency of at least 0.1 ms. By implementing this system, sales partners can monitor aquarium conditions in real-time, optimize the use of electrical devices, and replace manual draining methods with a more scalable and efficient system. the JSN SR04T sensor achieves a precision of ±0.5 cm. Data transmission delay analysis yields an average latency of at least 0.1 ms, supporting responsive real-time monitoring. In conclusion, this monitoring system is proven to be valid and reliable, offering a robust and time-efficient solution for IoT-based aquarium water quality management.

The Internet plays an important role in supporting academic and operational activities at Campus 4 of Universitas Garut, particularly for inter-faculty activities, seminars, and live streaming events. This study analyzes the Quality of Service (QoS) performance of the internet network using Wireshark for direct measurement and NS-2 for network simulation. The evaluation was conducted at three locations, namely the Administration Room (BAK), Auditorium, and Rooftop, during academic and non-academic days using QoS parameters including throughput, packet loss, delay, and jitter based on the TIPHON standard. The results show that during academic days, the BAK Room achieved a throughput of 447.8 Kbps, packet loss of 0.493%, delay of 20.487 ms, and jitter of 20.488 ms, while the Auditorium and Rooftop showed better performance with a good category. During non-academic days, network performance improved significantly, with throughput values of 1.044 Kbps in the BAK Room, 3.29 Mbps in the Auditorium, and 13.5 Mbps in the Rooftop, categorized as good to excellent. Overall, the network quality was classified as good, with an average QoS index of 3.75 or 94.75%. The NS-2 simulation results showed a similar trend to the Wireshark measurements. This study recommends increasing bandwidth capacity, implementing bandwidth management, and optimizing network usage to improve the quality of campus internet services.

Abstract

Distribution transformers play an important role in ensuring the continuity of electrical energy distribution, so an accurate diagnostic method is needed to detect damage. This study aims to analyze the condition of a 250 kVA UNINDO brand distribution transformer using a multi-parameter approach through Transformer Turns Ratio (TTR), Insulation Resistance (IR), and visual inspection tests. TTR testing was carried out at seven tap positions, while IR testing used a voltage of 5 kV. The results showed that phases A and B were still within the tolerance limit of ±1%, while phase C did not show a ratio reading indicating open winding. Very low insulation resistance values (0.02-0.05 MΩ) indicated significant insulation degradation. These findings were reinforced by visual inspections that showed physical damage and indications of overheating in the phase C winding. This study confirmed that the integration of TTR, IR, and visual inspection methods was able to improve the accuracy of transformer damage diagnosis and support condition-based maintenance decision making in the field.

Abstract

SF6 gas-insulated circuit breakers play an important role in power transmission systems by interrupting and connecting electrical current during both normal and fault conditions. This study aims to analyze the operation and maintenance of SF6 circuit breakers at the 150 kV Purbalingga Substation and evaluate their compliance with the operational standards of PT PLN (Persero). The research methods included field observation, interviews with substation operators, documentation study, and literature review. The results indicate that the SF6 gas pressure remained within the normal operating range of 0.55–0.65 MPa, the mechanical operating system functioned properly, and no significant gas leakage was detected. Maintenance activities were carried out periodically through daily, weekly, monthly, and annual inspections in accordance with PLN’s standard operating procedures. In addition, circuit breaker operations, both remotely through SCADA and manually by operators, were performed according to established switching procedures. The implementation of disciplined preventive maintenance enabled the SF6 circuit breakers at the 150 kV Purbalingga Substation to support the reliability and continuity of electrical power transmission effectively.

Abstract

Accurate estimation of soil resistivity is crucial in the design of grounding systems, yet it is often constrained by the lack of data at specific depths (blind spot). This study aims to validate a MATLAB-based linear interpolation computational method for estimating soil resistivity in blind spot areas. For validation purposes, secondary data from the study by Rukmana et al.  in a volcanic area at depths of 0.5 meters and 1.5 meters were used to predict the value at 1.0 meter, wichspre was then comparatively  tested against the actual field data. Computational results show that the estimated values range from 13.105 Ωm to 19.965 Ωm. Relative error analysis demonstrates varying accuracy levels, with the smallest deviation of 4.42% in linear trends and the largest at 26.99% due to volcanic soil moisture anomalies. Technically, these resistivity values meet the safety limits of the General Requirements for Electrical Installations (PUIL) 2020 standard. Based on this testing, the linear interpolation method proves to be sufficiently representative for preliminary design estimation. It is recommended to use a single rod electrode configuration at the location without the need for additional additive engineering.

Abstract

Sub-6 GHz metamaterial MIMO antenna for post-disaster emergency communication applications based on Unmanned Aerial Vehicle (UAV). Damage to telecommunications infrastructure during disasters causes communication interruptions, so a fast, flexible, and reliable emergency communication system is needed. UAV technology was chosen because it has high mobility and is able to function as an air base station in disaster-affected areas. However, the implementation of the MIMO system on UAVs faces obstacles in the form of mutual coupling between antenna elements due to limited installation space. Therefore, this study integrates a Complementary Split Ring Resonator (CSRR) metamaterial structure on a MIMO microstrip antenna to improve antenna performance. The research method is carried out through the design, simulation, optimization, fabrication, and antenna testing stages using CST Studio Suite and ANSYS HFSS software. The antenna is designed at a working frequency of 3.5 GHz to 5.8 GHz using a Rogers RT5880 substrate with a 2x2 MIMO configuration. The parameters analyzed include return loss, VSWR, gain, bandwidth, mutual coupling, isolation, Envelope Correlation Coefficient (ECC), and radiation efficiency. The results showed that the antenna was able to work optimally at Sub-6 GHz frequencies with a return loss value reaching -31.2 dB, VSWR 1.08, a gain of 9.8 dBi, a bandwidth of 1.15 GHz, and a radiation efficiency of 87.4%. The use of CSRR metamaterials succeeded in reducing mutual coupling from -12 dB to -24 dB and increasing isolation to 24.1 dB. The low ECC value of 0.011 indicates excellent MIMO diversity performance. The implementation of the antenna on the UAV also showed stable communication, low latency, and good data transmission under moving conditions. Based on these results, CSRR-based metamaterial MIMO antennas have great potential to be applied to post-disaster emergency communication systems because they are able to improve communication quality, expand signal coverage, and support real-time communication efficiently
