Abstract

This community service activity focuses on implementing an automatic nutrient control system called Airoponik (Airlangga Robot Hydroponic) for hydroponic farmer groups in Panderejo hamlet, Gempol, East Java. The system was developed to address the challenges in maintaining precise nutrient concentrations in hydroponic systems, which is crucial for optimal plant growth. The Airoponik prototype integrates Total Dissolved Solids (TDS) sensors, temperature sensors, and an automated control system based on ESP32 microcontroller, enabling automatic adjustment of nutrient levels within a ±5% tolerance range. The implementation process included prototype development, laboratory testing, and technology dissemination to the community. Testing results demonstrated successful nutrient control at various target levels (400, 700, and 1000 ppm). In addition to the functionality of the Airoponik system, its compact, suitcase-style design facilitates easy installation and adjustment of the device in space-constrained environments. To ensure effectiveness, observations revealed that the aeroponic system required only 43% of the maintenance time compared to conventional systems. The community response was highly positive, with 88% of participants expressing interest in adopting the technology, and achieving dissemination impact scores of 4.2/5.0. The integration with existing solar-powered hydroponic systems proved successful, providing a sustainable solution for automated nutrient management without dependence on grid electricity.

Abstract

Water is an important element in the life of living creatures, both for consumption and other purposes. Therefore clean water is crucial for human health and environmental protection. To determine the quality of water, whether it is safe for consumption or not, testing in a laboratory is required by testing the chemical elements and physical elements. This is because there are differences in determining whether water is suitable for use or not, the depth of the water also influences the differences in water quality, therefore we need the process of taking the water to be tested. Currently this process is carried out manually using manned vessels, this causes inefficiencies if carried out continuously. To overcome this problem, we need a tool that can collect water automatically. Unmanned Surface Vehicle (USV) is a vehicle that can walk on the surface of the water without passengers and can run manually using a Radio Control (RC) transmitter or automatically using the Pixhawk autopilot and Global Positioning System (GPS) as a localization system. This research aims to design an Unmanned Surface Vehicle (USV) that can take water samples automatically using the Pixhawk autopilot at a certain point and at a certain depth.
