Abstract

A hopper is a temporary storage container for rock material before it is fed by a feeder into a crusher. At PT Semen Padang, monitoring of material in the dosimat feeder hopper is still local, limiting supervision flexibility and response time, as well as lacking temperature and humidity control, which can degrade sensitive materials such as gypsum. This study aims to design an integrated system using Internet of Things (IoT) technology to overcome these limitations. The system employs an ESP32 microcontroller as the main processor, using an HC-SR04 ultrasonic sensor to measure material height and two DHT22 sensors to monitor temperature and humidity. Based on sensor readings, the ESP32 controls a DC motor for the filling conveyor and fans for cooling through a relay module. Real-time data visualization is implemented via the Blynk IoT platform for remote monitoring. Testing shows that the HC-SR04 sensor has an accuracy of 95.44%, while the DHT22 sensor achieves 98.62% accuracy. The automatic control system worked correctly according to logical conditions, and the configuration using four fans proved most effective for reducing temperature. Data transmission to Blynk was successful and consistent. In conclusion, the IoT-based monitoring and control system enhances operational efficiency and material quality in industrial settings. It provides a reliable model for implementing remote monitoring and automation, supporting modernization in similar industrial processes through improved supervision, environmental control, and system responsiveness

Abstract

Solar energy is one of the renewable energy sources that has great potential in Indonesia, due to its abundant availability and zero greenhouse gas emissions. However, the performance of solar panels can degrade due to high temperatures generated by continuous exposure to sunlight. This research aims to design and implement an effective cooling system to increase the output power of solar panels. The system is designed with a real time remote monitoring feature using the Blynk application, and is equipped with an automatic data logging  system  into  Google  Sheets.  The  cooling  mechanism  is carried out by spraying water onto the surface of the solar panel which is activated based on a predetermined temperature threshold value (set point). The test results show that the system is able to reduce  the  panel  temperature  by  5.46°C  and  increase  the  output power  by  1.76  W.  The  ratio  of  power  increase  to  temperature decrease is recorded at 3.1 W/°C, which proves that the system is effective   in   keeping   the   panel   temperature   below   40°C   and contributes significantly to the improvement of solar panel performance
