| Abstrak Niken Freindina, 2022. The Effectiveness of Tofu Waste Water as Substrate On Red Spinach (Amaranthus tricolor L.) Growth and Its Utilization as Learning Media. Thesis. Biology Education Study Program, Department of Mathematics and Natural Sciences Education, Faculty of Teacher Training and Education, Tadulako University, Palu. Supervisor: Mestawaty. As.A. Tofu waste water is a residual material produced from an activity and production process both on a household and industrial scale, which is directly disposed of and is no longer used. Whereas tofu waste water can still be processed and used as a substrate (EM4 and molasses) for plant growth. Therefore, this study aims to determine the effectiveness of tofu waste water as a substrate for the growth of red spinach (Amaranthus tricolor L.) and its use as learning media. The location of the activity is in the Laboratory and Green House for Biology Education, FKIP UNTAD. The type of research conducted is experimental. The type of research design used was a completely randomized design (CRD) consisting of 5 treatment levels and 4 replications, namely P0 = 0% without giving tofu waste water, P1 = 15% tofu waste water, P2 = 30% tofu waste water, P3 = 45% tofu waste water, P4 = 60% tofu waste water. The data obtained is using ANOVA analysis which is processed manually. The results showed that the treatment of tofu waste water as a substrate at the age of 1 WAP, 2 WAP, and 3 WAP was effective on the growth of height and number of leaves of red spinach plants at concentrations of 15%, 30%, 45%, and tofu wastewater was the most effective. used as a substrate for plant growth at a concentration of 60%. The implementation of the results of this study which was made in the form of a poster is suitable as a learning medium with a percentage of 82.3%.
