Abstract

The aim of this research was to determine the microcrystalline cellulose content in water hyacinth collected from Limboto Lake, Gorontalo. The stems of water hyacinth underwent a powder extraction technique to obtain alphacellulose, which was subsequently subjected to hydrolysis using HCl at concentrations of 2 N, 2.5 N, 3 N, 3.5 N, and 4 N. The results of microcrystalline cellulose hydrolysis are subsequently identified through several methods, including the use of iodine-potassium iodide solution, organoleptic testing, pH analysis, and qualitative tests involving solubility and starch content. The research results indicated that the alpha-cellulose obtained from the powder extraction technique weighed 320 grams, with microcrystalline cellulose yields of 77.13%, 74.05%, 72.82%, 60.77%, and 60.44% for the respective concentrations of HCl. pH analysis of the hydrolysis products for each HCl concentration revealed pH values of 6.82, 6.72, 6.62, 5.24, and 5.18. Solubility tests were conducted to assess whether the samples contained strong hydrogen bonds, making them insoluble in various solvents. he results showed that microcrystalline cellulose was insoluble in four solvents: water, 95% alcohol, 2 N HCl, 1 N sodium hydroxide, and ether. Qualitative testing for starch or carbohydrate content using iodine demonstrated that microcrystalline cellulose did not contain starch.
