Analisis Kadar Abu dan Kadar Serat Kasar pada Brachiaria ruziziensis di Loka Pengujian Standar Instrumen Ruminansia Kecil Menggunakan Metode Gravimetri

Abstract

Ash content is an inorganic substance that does not burn out and does not evaporate during the combustion process. The purpose of ash content is to check the nutritional value of grass and the total minerals contained in grass where the method used for ash content analysis is the gravimetric method. Fiber is one of the things that cannot be digested by human digestive enzymes. Crude fiber is tha part of food that cannot be hydrolyzed by the chemicals used to determine crude fiber content, namely sulfuric acid (H2SO4) and sodium hydroxide (NaOH). Analysisis of crude fiber levels is very importan tbecause fiber is known to have many benefits for the body, such as preventing constipation, preventing cancer, preventing painin the large intesstine and can help reduce cholesterol levels. The aim was to analyze the crude fiber content is Brachiaria ruziziensisgrass samples using the gravimetricreference and determine the crude fiber content in Brachiaria ruzizienisisgrasssamples. Thefibercontentcan be used to analyzethe processingprocess of grasssamples. Fiber can also be used to determine the nutritional value of a food ingredient by carrying out a heating and drying process using the gravimetric method. The results of the analysisof thepercent ash content obtained using Brachiaria ruziziensis samples were 8,3212%, 7,7972%, 7,7972% and percentage of crude fiber obtained using Brachiaria ruziziensis grass samples were 28,66%.
