Abstract

Monitoring the performance of Solar Power Plants (PLTS), especially off-grid systems, requires an effective and efficient data logger solution to collect data from multiple measurement points. Commercial data loggers are often constrained by high costs, limited capacity, and lack of flexibility. This research aims to design and implement a low-cost data logger system based on the CD4051B Multiplexer Integrated Circuit (IC) integrated with an Arduino UNO microcontroller. This system is designed to measure key parameters such as current (ACS712) and voltage (voltage sensor) from eight different channels, as well as environmental parameters (DHT11 and BH1750 sensors). The use of the CD4051B MUX IC allows for significant expansion of the Arduino UNO's analog inputs. Time data accuracy is ensured by the DS1307 Real-Time Clock (RTC) module, and data is stored in an SD card for long-term analysis. This approach is expected to produce an economical, reliable, flexible, and scalable data logger solution to meet the monitoring needs of off-grid PLTS, overcome the limitations of commercial data loggers and support performance optimization and maintenance of renewable energy systems

Abstract

Shrimp pond productivity is highly dependent on water quality, which is traditionally monitored manually through labor-intensive sampling and testing. This study proposes an IoT-based smart monitoring system to automate the assessment of water quality parameters such as temperature and salinity. The system employs an ESP32 microcontroller integrated with DS18B20 and salinity sensors. Sensor data are displayed in real time via a 4x20 LCD and the Blynk application. Two relays are included to automatically activate the aerator when temperature defined thresholds. Field testing over four days demonstrated sensor accuracy with error rates below 3%, stable data transmission, and effective automation. This system offers a reliable and efficient solution for shrimp farmers to monitor and manage water quality, potentially enhancing aquaculture productivity.

Abstract

The need for electrical energy continues to increase along with technological developments, so the utilization of solar energy as an alternative source is important. However, the efficiency of solar panels is greatly affected by the angle of incidence of sunlight which changes due to the rotation of the earth. To overcome this problem, a solar tracker is used. Solar tracker is a system designed to optimize the absorption of solar energy by adjusting the position of solar panels to keep them facing the direction of incoming sunlight. This research develops a stepper motor-based one-axis solar tracker to increase the efficiency of solar energy absorption. The system uses five main tracking positions that are adjusted to the movement of sunlight in the equatorial region. The stepper motor control is implemented using Arduino IDE and uses G-code program to simplify programming, while Real Time Clock (RTC) is used for scheduling automatic movement based on time. Results show the system has high accuracy in its positional displacement, making it an effective solution for tropical applications.

Abstract

  Efficient lighting that can be controlled flexibly is an important requirement in supporting comfort and energy efficiency, especially in residential environments. This research designs a lighting control system that can be accessed through various methods, such as touch screens, mobile applications, and physical switches, to provide flexibility in setting light intensity according to user needs. This system design uses an ESP32 microcontroller as the main control center connected to relays, a TFT touchscreen-based interface, a physical switch, and an internet-based Blynk application. The light intensity setting is done using RBDdimmer-based AC dimmer module, and the power consumption monitoring is done through PZEM0-004T sensor. Control and monitoring data are synchronized in real-time between control methods. Test results show that the system is able to properly manage lighting through three control paths in a synchronous manner, even when an internet connection is not available. The system is capable of automatically saving and restoring the last status, and makes it easy for users to adjust the lighting according to their preferences. With these features, this system can be implemented in an efficient IoT-based smart lighting concept

Abstract

Indonesia's agricultural sector faces the challenges of climate change and land constraints that drive the need for sustainable agricultural technology innovation. This research designed a Deep Flow Technique (DFT) hydroponic system based on Arduino Mega 2560 which is integrated with a Solar Power Plant (PLTS). The system uses a DFRobot TDS sensor for nutrient monitoring, an HC-SR04 ultrasonic sensor for water level detection, an ACS712 voltage and current sensor for electrical monitoring, and an I2C LCD for the display. The integration of solar power with solar panels, MPPT, and batteries provides sustainable energy. The test results showed that the TDS sensor had an accuracy with an error of 1.38%-41.11%, the ultrasonic sensor showed good reading consistency, and the electrical sensor gave the results according to the reference. Testing of the overall system proves the integration is successful with real-time monitoring capabilities and automatic controls. The solar power system has succeeded in providing stable energy for independent operations. The research resulted in an automated hydroponic prototype that improves production efficiency with the support of renewable energy.
