The Influence of River Filtration Water on the Nutritional Content of Red Spinach Plants (Amaranthus tricolor L)

Background: The cultivation of red spinach in urban farming is expected to meet the needs of people in urban areas for vegetable consumption. It is feared that using contaminated river water for irrigation will reduce the nutritional value of spinach plants. The purpose of this study was to determine the effect of water filtration on the nutritional content of Red Spinach plants (Amaranthus tricolor L).

Methods: This is an experimental study with a post test control group design.

Results: The results showed that the quality of the filtered water was superior to river water and met the Indonesian Government Regulation Attachment VI of the National Water Quality Standard, making it suitable for crop irrigation. The highest water content found in leaves with water filtration treatment was 86.464%, and the highest protein content in leaves with a value of 0.934% in the filtration water treatment, and the best fat content in leaves with a concentration value of 0.0631% in the filtration water treatment. The Fe, Ca, Vit A, and Vit C content remained relatively constant across the three treatments.

Conclusion: Filtered water treatment yields superior results and is more likely to be used to replace river water.
