Abstract

Pertumbuhan penduduk meningkatkan permintaan sayuran segar, mendorong adopsi teknologi hidroponik yang menanam tanaman tanpa tanah menggunakan larutan nutrisi. Sistem ini meningkatkan produktivitas di lahan sempit dan menambah nilai estetika, serta menghindari penggunaan pestisida. Namun, pengaturan parameter seperti pH, oksigen, dan suhu diperlukan untuk menjaga pertumbuhan tanaman, terutama di lingkungan ekstrem seperti Semarang. Kegiatan pengabdian  mengimplementasikan teknologi IoT dalam sistem hidroponik apung di Nurusunnah Farm, Semarang. Teknologi ini memungkinkan pemantauan dan pengendalian parameter secara real-time, mengurangi beban kerja manual dan meningkatkan efisiensi serta produktivitas tanaman selada keriting. Kegiatan ini mencakup survei, perancangan, instalasi, pelatihan, dan evaluasi. Teknologi mampu melakukan pemantauan dan pengendalian parameter secara real-time, mengurangi beban kerja manual dan diharapkan meningkatkan produktivitas tanaman selada keriting. Hasil implementasi menunjukkan sistem yang dibuat dapat berjalan secara otomatis menggunakan teknologi IoT sehingga meningkatkan efisiensi pengelolaan kebun sekaligus mengurangi ketergantungan pada intervensi manual.

Abstract

This community service activity aims to help the ornamental plant business at "Surya Nursery," located in Pedalangan Village, Semarang, overcome plant care constraints due to limited time and human resources. The technology applied is an Arduino UNO-based automatic plant waterer equipped with a webcam for real-time monitoring in the business environment. The watering tool consists of 5 sprinklers that can rotate 360 degrees for an area of 200 square meters and can operate automatically or manually depending on the needs of the partner.Through this program, the team provides training and assistance to business partners, starting from device installation, system use, and maintenance of the technology applied. This system is expected to increase time efficiency, reduce water consumption, and maintain plant quality consistently.The results of this activity show that the tool can operate well, and partners feel the benefits in the form of increased productivity and reduced daily workload. The technology applied also opens up opportunities for "Surya Nursery" to increase competitiveness in the ornamental plant market. With this program, it is hoped that similar technology can be adopted by other small and medium enterprises in the agricultural sector.

Abstract

The rapid development of technology significantly impacts various aspects of life, including the field of livestock farming. The advancement of technology is expected to enhance the rate and effectiveness of production, particularly in the hatching of chicken eggs or chick breeding. The existing technology relies on manual on/off systems and manual monitoring, hindering successful egg-hatching rates and percentages. Therefore, this research aims to explain the development of an automated egg incubator using a Proportional Integral Derivative (PID) control system with hypertuning parameters, as well as temperature and humidity monitoring, along with a protection system based on voltage sensors, all integrated with the Internet of Things (IoT). The PID control is employed to regulate the temperature of the egg incubator, ensuring stability according to the predetermined set point temperature. The IoT system in this study comprises an ESP32 node as a microcontroller connected to a sensor, using Firebase and User app for monitoring the egg incubator. The study employed PID control with parameter values Kp=10, Ki=3, and Kd=8. The research yielded time-efficient egg incubation and prevention of turning delays. The DHT21 sensor achieved a 90% success rate in detecting room temperature (38°C) and humidity (77%-84%) within the incubator, while PID control effectively maintained the target temperature. The ACS712 sensor accurately detected current in the heater, power supply, and motor. The Kodular application can display sensor readings. The future implication is developing a more adaptive PID method toward changes and nonlinear dynamics.

Abstract

Renewable energy, particularly solar power, is widely recognized as a clean and sustainable resource, with rooftop photovoltaic (PV) systems playing a vital role in electricity generation. However, high temperatures can significantly reduce their efficiency, making effective cooling systems essential. This study proposes a proportional-integral-derivative (PID) based cooling control system for rooftop PV panels, integrating an adaptive Mamdani fuzzy logic controller to optimize PID parameters dynamically. The methodology includes system modeling, hardware and software implementation, and comparative testing between the Mamdani fuzzy-PID controller and the Ziegler-Nichols PID method. Experimental results show that both controllers effectively regulate PV panel temperature at 36 °C. The Ziegler-Nichols PID achieves faster settling time of 6.45 minutes with a steady-state error of 1.345%, whereas the Mamdani fuzzy-PID reduces the steady-state error to 0.93% but with a longer settling time of 9.15 minutes. These results indicate that the fuzzy-PID controller offers better accuracy and system stability, making it a promising solution for maintaining PV performance under varying environmental conditions. The key novelty of this study lies in its adaptive approach, where the Mamdany fuzzy-PID controller continuously adjust control parameters (Kp,Ki,Kd) in real time, resulting in more consistent and precise temperature regulation than conventional PID tuning methods.

Abstract

Vegetable farmers in Bebengan Village, Kendal Regency, still mostly water their crops manually, resulting in inefficient water usage and inconsistent watering timing. Additionally, the water quality for irrigation has not been monitored regularly, even though pH and PPM parameters affect nutrient availability and plant growth. This service activity aims to implement an Internet of Things (IoT)-based automatic plant watering technology that can monitor pH and PPM and provide easy control through Google Assistant. The implementation methods include observing partner needs, designing and assembling an Arduino ATmega 2560 and ESP8266-based system with pH and PPM sensors, installing it on a 200 m² cultivation area, integrating remote monitoring and control, and training farmers on operating and maintaining the equipment. Implementing the system allows for more scheduled/controlled watering and provides real-time pH and PPM information as a basis for decision-making. In conclusion, the implementation of this IoT system improves the effectiveness of the watering process, supports water quality monitoring, and simplifies operations through voice-based control, thus potentially increasing cultivation efficiency at the farmer level.

Abstract

This study compares the performance of Gain Scheduling Proportional–Integral–Derivative (GS-PID) control and Fuzzy Mamdani control applied to an air heating module. The system was implemented using an STM32 microcontroller and evaluated experimentally under temperature setpoints of 50 °C, 60 °C, 70 °C, and 80 °C. Performance was assessed based on dynamic response parameters, including rise time, overshoot, steady-state error (SSE), Integral of Absolute Error (IAE), Integral of Squared Error (ISE), and Integral of Time-weighted Absolute Error (ITAE). The experimental results show distinct characteristics between the Gain Scheduling PID (GS-PID) and Fuzzy Mamdani controllers under varying setpoints. The GS-PID controller exhibits a rise time of approximately 4.0–4.9 s with relatively small overshoot in the range of 1.18–2.87%, while maintaining a very low steady-state error of about 0.001–0.24%. In contrast, the Fuzzy Mamdani controller achieves a faster rise time of around 2.0–2.6 s at low to medium setpoints, which increases to approximately 5 s at higher temperatures. The overshoot produced by the Fuzzy Mamdani method ranges from 0–4.78%, decreasing as the setpoint increases, with zero overshoot observed at high setpoints due to incomplete setpoint tracking. Moreover, the Fuzzy Mamdani controller yields higher performance index values (IAE, ISE, and ITAE), indicating larger accumulated error over time. Overall, GS-PID control is more effective in ensuring steady-state accuracy and stability, whereas Fuzzy Mamdani control provides a faster transient response at lower operating temperatures.
