Abstract

Gummy plants can be utilized as adhesives for paper, soil, and as a source of the enzyme protase, which is widely used in the food industry. Adhesives that are able to bind soil must have a fixed weight and composition so that the level of stickiness remains stable. Usually, adhesives are made from organic materials that have the ability to bond soil particles. In utilizing biomaterials as soil adhesives for plant growing media, allelopathy testing is one of the things that must be considered. Some studies show that allelochemicals contained in plant extracts at certain concentrations can inhibit the germination and growth of weeds and plants. This is evidence of the potential of allelochemicals as natural or biological herbicides that are easy to use, cost-effective, and environmentally friendly. Based on this, the potential and possibility of allelopathy possessed by the Kersen plant (Muntingia calabura L.) as a biomaterial for soil adhesives in producing plant media was tested. This research was conducted using the Completely Randomized Design (CRD) method with 13 treatments and 4 repetitions. Kersen plants (Muntingia Calabura L.) have allelopathic abilities that are seen in high concentrations against mustard plants (Brassica juncea L.) and lettuce (Lactuca sativa). The difference in the allelopathic ability of various parts of Muntingia Calabura L. plants depends on the concentration and compounds contained in the plant parts. Allelopathic index value of branches, leaves and fruits of Muntingia Calabura L. plants on Brassica juncea L. and Lactuca sativa plants, all treatments with low to medium concentrations (6.25%-40%) did not inhibit growth, even tended to stimulate the growth of test plants. Conversely, at high concentrations, there was a decrease in the allelopathic index value. Old fresh branches and dried leaves tended to have the mildest or even beneficial allelopathic effect, while young fresh leaves and fruits showed a faster decline in the index at high concentrations. Key words: Allelopathic compounds, Growth of seedlings and planting seeds, Kersen plant, Muntingia calabura L.
