The Effectiveness of Sludge in the Leaf Fermentation Process

Abstract

Wet leaves that are decomposed with mud can cause the leaf tissue to peel and become transparent. This scientific study aims to determine the effect of various mud media from rivers, ponds and gutters on the flaking of soursop (Annona muricata L.) leaf tissue. This study uses 3 variations of mud taken from river ponds and ditches designed using the RAL design (Complete Randomized Design). Each mud medium in a container was filled with fresh soursop leaves with the leaf criteria of the fourth node of each tree branch. The Kruskal Wallis hypothesis test with a significance level of 0.05 was used in making decisions, which was then continued with the LSD test to determine the difference in effect between treatments. In the calculation of the peeling percentage of leaf tissue, it was found that the river and pond mud soaking media had a percentage of 100% and only 6.9% of the gutter, which means that river and pond mud had good potential as a medium for leaf fermentation. In the immersion photo, it was found that the river mud had more complete stripping of tissue. The exfoliating quality of leaf tissue in this study was influenced by the type of sludge medium and its pH.
