Abstract

This study aims to determine the effect of liquid organic fertilizer (POC) concentration from a mixture of coconut fiber and petai cina leaves on the growth of Pakcoy mustard plants (Brassica rapa L.) and to determine the optimal POC concentration for the growth of Pakcoy mustard plants. This study used an experimental method with a Completely Randomized Design (CRD) consisting of six treatments and four replications, namely P0 (0%), P1 (15%), P2 (30%), P3 (45%), P4 (60%), and P5 (75%). Observation data were analyzed using the ANOVA test followed by the Duncan test. The results showed that the average best growth of Pakcoy mustard plants for each parameter was; the number of leaves was 15; the fresh weight of the shoot was 78.98 gr; the fresh weight of the root was 1.69 gr; the dry weight of the shoot was 2.86 gr; and the dry weight of the root was 0.30 gr. The concentration of POC in treatment P3 (45%) is the recommended concentration for the parameters of Leaf Number, Weight, while the recommended concentration for the wet weight of shoots, dry weight of shoots, wet weight of roots, and dry weight of roots is 60%. Based on these results, it can be concluded that POC from a mixture of coconut fiber and petai cina leaves has a significant effect on the growth of Pakchoy mustard plants in all parameters. The results of this study are used as a learning resource in the form of Student Worksheets (LKPD) for the subject of Biology for grade XII of high school on the topic of growth and development of living things. Keywords: Chinese Stink Bean Leaves, Coconut Fiber, Growth, Pakcoy Mustard Greens,POC.
