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

This paper discusses the design, construction, and testing of a water flow control and monitoring system in pipes that aims to detect leaks and combine water flow in real time to improve efficiency and reduce potential losses due to leaks. This system is designed using water flow sensors placed in each channel in a certain number to detect the air flow rate. The difference in air flow read from several sensors is used as an indication of a leak. This system is integrated with a microcontroller and is equipped with control via an electric solenoid valve that allows for leak handling and air flow diversion when needed. Several tests have been conducted to ensure the system is ready for use, and the results show that the system is able to control air flow well without any problems, and is able to monitor air flow in real time, detecting changes in flow when a leak occurs. This research contributes to a device for controlling and monitoring water flow in pipes to improve the efficiency of water channel handling

Abstract

The utilization of waste oil as an alternative cooking fuel is limited by its complex ignition process, which requires preheating to reduce viscosity and ensure stable combustion. Conventional methods, such as burning tissue paper, are unsafe, inefficient, and impractical, hindering broader adoption. This study presents the development of an automatic preheating system for waste oil stoves using an ESP32 microcontroller and HMI with TFT LCD display. The system integrates a thermocouple sensor for accurate real-time temperature monitoring and an automatic cut-off mechanism to halt fuel supply during ignition failure, and includes a buzzer for audible alarms during safety shutdowns to improving operational safety. The ignition sequence employs LPG as a preheater before automatically switching to waste oil at the optimal temperature, with programmed control of the blower, igniter, and valves. Experimental results showed thermocouple measurement accuracy with an average error of 4% and high reliability in fuel transition, except at low initial temperatures (31°C and 42°C) where insufficient heating time resulted in high viscosity and transition failure. The safety system effectively prevented hazards, while the HMI provided precise control and monitoring of actuators and combustion conditions. Overall, the proposed system enhances the safety, reliability, and practicality of waste oil stoves and demonstrates potential for industry innovation and renewable energy applications. Nevertheless, the system still requires LPG for the preheating stage and continuous electrical power, which can reduce effectiveness and make it harder to use in mobile or areas without electricity.
