Analisis Kadar Serat Kasar pada Rumput Stenotaphrum secundatum di Loka Pengujian Standar Instrumen Ruminansia Kecil Menggunakan Metode Gravimetri

Abstract

Grass is the main feed for ruminant livestock whose availability is very necessary quantitatively and qualitatively throughout the year in ruminant livestock production. Analysis of crude fiber content in Stenotaphrum secundatum grass was carried out at the Small Ruminant Instrument Standard Testing Workshop. Crude fiber is a part of food that cannot be hydrolyzed by chemicals. In the analysis of crude fiber content used to determine the crude fiber content of a sample, namely H2SO4 and NaOH. The aim of analyzing crude fiber content is to examine the nutritional value contained in Stenotaphrum secundatum grass in the LPSI RK animal feed laboratory. The method used to analyze crude fiber content is the gravimetric method. Gravimetric analysis is an analysis based on the process of isolating and measuring the weight of a particular element or compound, by carrying out precipitation, evaporation and electrolysis methods on samples. The results of the analysis of the percent crude fiber content obtained from Stenotaphrum secundatum grass were 32.40%, 32.47% and 32.65% with an average of 32.5%. In accordance with the animal feed resource information system (feedipedia 2024), the average crude fiber content of Stenotaphrum secundatum grass is 32.5%, which meets nutritional content standards.
