IoT-based pH Monitoring for Nutrient Absorption Efficiency in Hydroponic Plant at Pion Hidrofarm Start-Up

Abstract

Farming land in Malang City is getting more limited because several agricultural areas have changed their function to housing or commercial areas such as cafes. Pion Hidrofarm, a startup company in Malang City, demonstrated how to use this hydroponic technique to save land by arranging it vertically and on narrow land. This research aims to make a simple prototype in the form of a tool that can monitor the pH of water nutrients. In addition, this device will also neutralize the pH of the water automatically. The method used in this research is a single case study using a design thinking approach. The author studied literature from various sources as secondary data to support the research. Four stages have been carried out, starting from learning the concept of hydroponic growing media to buying model “A” hydroponic media with 180 planting holes. The fifth stage currently being researched is monitoring the pH of the water. In addition, this tool also functions to neutralize the pH of the water automatically if there is a pH swing with a value above or below the threshold. If automatic neutralization cannot run for some time, it will notify the farmer for manual action.
