Abstract

The purpose of this study was to determine the effect of using liquid organic fertilizer made from tofu solid waste and banana peel waste on the growth and production of green mustard plants and to determine the dosage of liquid organic fertilizer that gives the best results for the growth and production of green mustard plants.This study is an experimental study using a completely randomized design consisting of 5 treatments, each repeated 5 times. The 5 treatments are liquid organic fertilizer made from tofu solid waste and banana peel waste, namely control/without POC 0 ml (P0), POC 50 ml (P1), POC 100 ml (P2), POC 200 ml (P3), and POC 400 ml (P4). The parameters observed were leaf width and plant fresh weight. The observation data were analyzed using an ANOVA test, followed by a post-hoc least significant difference (LSD) test.The results of the study indicate that the application of liquid organic fertilizer made from tofu solid waste and banana peel waste has a significant effect on the growth and production of green mustard plants, as evidenced by the ANOVA test results showing an Fcalculated value > Ftable value. The Fcalculated value for the leaf width parameter was 183.336 (> Ftable 1% = 4.43), and the Fcalculated value for the fresh weight parameter was 49.36707 (> Ftable 1% = 4.43). From the BNT followup test, the value obtained for the leaf width parameter was 0.77, and the BNT follow-up test result for the fresh weight parameter was 12.74.

Abstract

This study aims to determine the effect of the most effective volume of watering for Sargassum sp liquid organic fertilizer on the growth of red chili plants. The study was an experimental study using a completely randomized design with 5 treatments of watering volume of Sargassum sp liquid organic fertilizer, namely 0 mL (control), 50 mL, 100 mL, 150 mL, and 200 mL. Each treatment was repeated 4 times. The variables measured were plant height, number of leaves, and number of branches. Observational data were analyzed using analysis of variance and further tested by BNT. The results of the analysis of variance showed that the organic fertilizer treatment of Sargassum sp. very significant effect on the variables of plant height, number of leaves, and number of branches, where each variable shows the value of Fcount > Ftable. Further test results showed that the best treatment was Sargassum sp treatment with a watering volume of 200 mL/polybag.
