Abstract

The primary objective of developing the project titled "Smart Aquaculture in Internet of Things-based Catfish Farming" is to create a specialized tool for catfish farming that facilitates automated monitoring and control of water quality, eliminating the need for manual intervention at the aquaculture pond. The collected data is made accessible through a web monitoring system. The tool aims to mitigate catfish mortality risks, enhance yield, and streamline the cultivation process. The development process of this tool encompasses several stages, which are as follows: (1) Requirements Analysis, involving the identification of necessary tools and materials for the project; (2) Implementation, encompassing the design and fabrication of the tool, outlining the circuit scheme, and detailing the step-by-step manufacturing process; (3) Testing, describing the procedures and results of evaluating the tool's performance. The monitoring system employs PH- 4502C sensors, DS18B20 temperature sensor, and HC-SR04 level sensor, all controlled by ESP32 DevKit. Comparative analysis against standard measuring instruments demonstrates an average error percentage of 1.64% for pH, 0.88% for temperature, and 0.70% for water level measurements. Additionally, the data transmission test reveals a delay of 19.16 seconds, while the actuator response test, based on sensor readings, successfully operates within the system's intended parameters.

Abstract

Hydroponic farming has become an attractive option in strawberry cultivation as it provides better control over the growing environment of the plants. However, proper management and continuous monitoring are challenges often faced by farmers in hydroponic farming practices. Therefore, in this study, we designed an IoT-based application that aims to monitor and control strawberry hydroponic farming through smartphone devices. The method used in this research involves developing an application that connects with various sensors installed in the hydroponic farm environment. The data obtained from the sensors is transmitted in realtime through the IoT network. In addition to the monitoring function, the application is also equipped with a control system that can be customized according to the needs of farmers. The result of this research is an application that can work from a short distance (local) or a long distance (cloud). The application is equipped with a hazard alarm notification system. The feature allows farmers to take action to maintain the health and quality of strawberry plants. The use of this application is expected to help make it easier for farmers to monitor and control hydroponic farming to be more efficient and optimize crop yields.

Abstract

Strawberries are a fruit that is a superior commodity in growing the economy in Indonesia. However, there was a decline in strawberry production from 2017 to 2021. This was due to constraints in the conventional cultivation process and environmental controls that were not yet optimal. This research focuses on designing an automated system for cultivating strawberries in containers using several sensors. The sensors used are the EC sensor to measure hydroponic nutrient levels, the pH sensor to measure water acidity, and the DHT22 sensor to measure temperature and humidity. Sensor data is sent to the server using IoT technology. Data is also visualized through an Android application that can be monitored from anywhere and at any time. The design of the automation system, named Amanda Mini, delivers the right amount of nutrients so that the health and nutrition of strawberry plants are sufficient. Water flow is carried out automatically using water supply pumps, sample pumps, stirrer pumps, and plant pumps. In this way, the Amanda Mini automation system facilitates hydroponic strawberry cultivation activities, which can increase strawberry production.

Abstract

Workshop is one of the places that contributes a significant amount of carbon monoxide gas, originating from motor vehicle exhaust. A workshop is also a place at high risk of fire. Due to the lack of awareness among visi- tors and workshop workers about the dangers of carbon monoxide gas and the potential for fires in motorcycle workshops, a tool is needed to monitor carbon monoxide levels and detect fire in the workshop. The aim of this final project is to design and develop a device, software, and demonstrate the per- formance of a system for monitoring carbon monoxide levels and detecting fire in a motorcycle workshop. This research uses the Research and Develop- ment (R&D) method. The results of the monitoring system created showed good outcomes. The sensor used was able to read carbon monoxide levels with an error rate of 5.56%, while the Flame sensor was able to detect fire at a maximum distance of up to 70 cm. The monitoring system functioned well, with carbon monoxide levels visualized using ThingSpeak. The DC fan also worked effectively, when carbon monoxide levels in the room reached 25 ppm or higher, the DC fan would turn on and help with air circulation.

Abstract

This research designs and implements a real-time power consumption control system on an OpenWRT-based MikroTik hAP ac² router using a PID Controller on an ESP32 microcontroller. The system utilizes the INA219 sensor to precisely measure power consumption and accesses network parameters such as throughput, latency, and the number of active users through the Open-WRT module to adjust power control to network conditions. The research method was carried out by testing nine PID parameter configurations and one uncontrolled configuration for comparison. Each configuration was tested under various network load scenarios, with power consumption and network performance data continuously recorded. The analysis was conducted using ITAE (Integral Time Absolute Error) calculations to evaluate control quality, and ANOVA statistical testing to determine the significance of differences between configurations. The test results showed that the optimal PID con-figuration (Kp = 1,5; Ki = 0,5; Kd = 0,2) was able to reduce average power consumption to 7,418 W with an ITAE of 2.419 and stable throughput. This research provides an effective contribution for implementation in small-to-medium scale energy-efficient networks.

Abstract

This study developed a real-time road damage detection system on an edge device to address the inefficiency and subjectivity of manual monitoring. Following the Engineering Design Process (EDP), the system uses a YOLOv11 model—trained in PyTorch and converted to ONNX for optimization—to classify four types of road damage on a Raspberry Pi 5, integrated with a GPS module for automatic coordinate recording. Field evaluation showed that after optimization, the system achieved an average processing speed of 3.66 FPS with an inference latency of 277.69 ms, while maintaining efficient resource usage (45.06% RAM, 65.05% CPU load) and an mAP@50 of 0.554. These results demonstrate the feasibility of an autonomous, accurate, real-time road damage detection system on a low-cost edge computing platform, producing geospatial data ready to support operational decision-making in road maintenance.
