The Effect Of Mixing Concentrations Of Raw Materials: Coconut Fibre, Banana Fronds, And Water Hyacinth On The Content Of Carbon, Nitrogen, Phospor, And Potassium (CPNK) And Biodegradation In Organic Mulch Sheet Planting Media.

Abstract

This study investigates the potential of agricultural biomass waste, including coconut fibre, banana fronds, and water hyacinth to produce organic sheet mulch with optimal Carbon, Nitrogen, Phosphorus, and Potassium (CPNK) content and biodegradation properties. By evaluating the effect of mixing concentrations of raw materials, this research aims to develop a sustainable and eco-friendly planting medium that supports sustainable agriculture. : This study used a Randomised Group Design (RCD) with nine treatment variations and three replications to investigate the effects of mixing raw material concentrations on the properties of organic mulch sheets. Experimental data were analyzed using the SPSS 16 Two-Way Analysis of Variance method and Duncan's Multiple Range Test (DMRT) to determine significant differences in organic mulch sheet parameters, the properties of the organic mulch sheets, including moisture content, ash content, and biodegradability. In addition, the CPNK test was conducted to characterize the organic mulch sheets further. The optimal treatment will be identified using the Zeleny method. The results showed that the biodegradability ranged from 26.68% to 50.38%, C- organic at 57.8%, N-total at 0.355%, Phospor at 0.531%, and Potassium at 0.8355%. The organic sheet mulch developed in this study is a promising eco-friendly planting medium that supports sustainable agriculture. The findings provide a foundation for future research on biodegradable mulch materials
