Abstract

Indonesia's population growth has increased every year which has an impact on the conversion of agricultural land into settlements. Hydroponics is a solution to the conversion of agricultural land. Hydroponics is a farming system without soil. In hydroponics, pH and nutrient levels are very important to keep plants growing properly. However, there are obstacles in the hydroponic farming system, namely in terms of controlling pH and nutrient levels which are still done manually. the result of not optimally controlling pH and nutrient levels in hydroponics will result in less optimal plant growth and even plant death. Therefore, we need a tool that can control pH and nutrient levels by using an Arduino microcontroller as a controller, a pH meter sensor to measure pH levels, and a TDS meter to measure nutrient levels. In this research, the hydroponic system used is the Nutrient Film Technique system, which is a hydroponic system that uses shallow water flow. This research was conducted in the hydroponic lab at the University of Perjuangan, Tasikmalaya, which still controls the levels of nutrients and the pH of the water used for hydroponic plants, which is still done manually. The results of this research are that the tool is designed to be able to maintain pH levels and nutrient levels for hydroponic lettuce plants with an error rate of 1.6% for pH sensors and 0.6% for TDS sensors which allows pH and nutrient levels for lettuce to be sufficient and stable.

Abstract

Warehouse management in large industries and SMEs (Small and Medium Enterprises) in Indonesia is a critical aspect that must be addressed seriously. Most warehouse systems still rely on manual processes, such as checking humidity, temperature, and gas levels in the storage area. This approach is inefficient as it requires significant time and manpower for regular monitoring. Manual operations using human resources have limitations in terms of labor, time efficiency, accuracy, and operational costs, such as employee wages. To address these challenges, this study proposes the development of an automated system based on the ESP32 microcontroller, which serves as a full controller, utilizing the DHT-11 sensor for temperature and humidity measurement, and the MQ-135 sensor for gas detection. Additionally, Python programming is implemented for data visualization, allowing real-time display on a laptop or computer to facilitate warehouse monitoring. The system developed is designed to read, control, and transmit sensor data. It can measure humidity, temperature, and gas concentration (PPM) and control actuators, such as a relay to activate a buzzer or light, according to the algorithm programmed into the ESP32. The results indicate that the system is capable of reading temperature and humidity with a data error rate of 6%, and gas concentration with an error rate of 2%. Additionally, the data transmission and visualization are functioning properly, in real-time
