IDENTIFIKASI BUTIR-BUTIR LEMAK DAN BAKTERI PATOGEN PADA SUSU DENGAN MENGGUNAKAN MIKROSKOP BINOKULAR XSZ-107BN (IDENTIFICATION OF GRAIN’S FAT AND BACTERIA IN MILK USING PATHOGEN BINOCULAR MICROSCOPE XSZ-107BN)

Abstract

Milk consists of fat that can be as oil in water emulsion. The fat part can be separated easily because its density is small. Because it has a large surface area, chemical reactions occur on the surface is easy once the border between the fat and the medium. Extensive surface can occur because the fat is in the form of globules having diameters ranging from 0.1 micrometers-15 micrometers. In milk fat contained in three places, namely in the globule, the membrane material and in the serum and milk beside it also has considerable pathogenic bacteria paracit.Untuk knowing grains - grains of fat and bacterial pathogens in perlukannya a tool called instrument with a microscope. microscope is a tool that is widely used instruments the researchers to look at a very small objects or objects that can not be seen with the naked eye. At 4X magnification (time) and 10X (time) grains - grains of fat and bacterial pathogens in milk clearly visible at the time identified with a microscope. Grain - grain visible fat with prominent granular appearance of the milk while the discovery of pathogenic bacteria easy red bubbles indicating gram negative.
