Abstract

Rubber plants (Hevea brasiliensis) will experience a decrease in production as plants age and the nutrient content in the soil decreases. This study aims to find out the chemical properties of soil on plantations of rubber crops that are converted into palm and coconut crops. The research was conducted from Februari 2023 to Agustus 2024 at the palm coconut plantation of PTPN III Aek Nabara North Garden in Labuhanbatu district and analyzed in the Land Laboratory of the Faculty of Agriculture of the University of Northern Sumatra. The methods used are observation methods, field sampling, and analysis in the laboratory to obtain quantitative data. Observation parameters include soil pH, C-organic, Total Nitrogen, Available P, Cation Interchange Capacity, and Base Fulness. The results of the survey showed that the level of soil fertility at the site of the research was included in the low category. The main limiting factor that causes the low fertility of the soil is the low content of organic material in the soil. In order to improve the fertility status of the ground at the research site for further planting, it is necessary to make efforts such as irrigation and fertilization, as well as the addition of organic materials, to make the availability of nutrients for plants more affordable. Keywords: replanting area, rubber plants, conversion, soil fertility, quantitative data

Abstract

In general, this study aims to see whether Andaliman extract is able to inhibit the growth of Escherichia coli microorganisms. the first step in this research is the extraction of Andaliman with 4 types of solvents (equates solvents, methanol, ethyl acetate, n-hexane). In the second stage, phytochemical tests were carried out on the andaliman extract to see the content of the active compounds in the andaliman extract, in the andaliman extract the active compounds were found to be alkaloids, steroids, and free-form triterpenes, saponins, tannins, flavonoids, and glycosides. The third stage of this study was the zone activity test. inhibit andaliman extract on Escherichia Coli assay on bay leaf extract using blank disc paper. The extract solution that has been diluted with a concentration of 25%, 50%, 75%, 100%, Andaliman extract with an ethyl-acetate solvent with a concentration of 100% has the greatest inhibition on the growth of Escherichia coli with dimensions of 19.15 mm, while the has the smallest inhibition of hexane solvent with a concentration of 25% at 5.80 mm.
