Abstract

The Internet of Things (IoT) technology has brought innovation to various fields, including agriculture and plantations. One of the main challenges in plant cultivation is maintaining consistent irrigation to ensure that plants receive an optimal amount of water. Improper watering can lead to either water deficiency or excess, negatively impacting plant growth and productivity. An IoT-based automatic irrigation system is designed to address this issue by utilizing soil moisture, temperature, and humidity sensors to accurately determine the water needs of plants. The data collected by the sensors is processed by a microcontroller, which then automatically controls the water pump. Additionally, users can monitor and manage irrigation through a smartphone application, allowing for more efficient and flexible watering. With the implementation of this system, it is expected that productivity and efficiency in plant management, both at the household and commercial farming levels, can be significantly improved.

Abstract

The quality of drinking water is a critical factor that impacts an individual's health. Contaminated drinking water can serve as a medium for disease transmission and lead to the decline in organ function. The lack of public awareness about the standards for safe drinking water has prompted educational initiatives for the students of Instrumentation and Control Engineering Technology program at Politeknik Negeri Indramayu. This initiative included a presentation, interactive discussions, and an evaluation. Following their participation, most students gained a better understanding of the criteria for safe drinking water and became more aware of the importance of monitoring water quality. They also expressed interest in developing technologies to detect drinking water quality as an innovative solution for public health. Furthermore, implementation of this activity is expected to accelerate the adoption of drinking water quality monitoring technologies, ultimately reducing the risk of waterborne diseases.

Abstract

The mango cooling monitoring system based on the Internet of Things (IoT) is developed to maintain quality and freshness during storage. This study utilizes the ESP32 module as the central processing unit, integrated with DHT22 temperature and humidity sensors, enabling real-time monitoring. The collected data is transmitted to an IoT platform for remote monitoring. Testing results indicate that the system accurately monitors storage conditions with minimal error rates. The implementation of IoT technolody enhances user convenience, improves storage efficiency, and reduce product loss due to improres handling. This research is expected to contribute to the advancement of agricultural technology and the optimization of agricultural product distribution.

Abstract

Freshwater lobsters (Cherax) are cultivated using freshwater, with an ideal water temperature range of 21 to 28 °C. However, achieving and maintaining this temperature range requires a temperature control system. In this case, several control components are used, including a thermostat, TDR, contactor, and selector switch. The thermostat is employed to automatically regulate water temperature, while the TDR functions to reduce the compressor’s workload during startup and to control the operation of the water circulation pump by delaying cooling before circulation begins. The cooling system, equipped with two evaporators, is capable of reaching the initial temperature within 40 minutes and achieving 21 °C in the subsequent 30 minutes. When the system is turned off, the water temperature rises from 21 to 24 °C within 1 hour and 40 minutes.
