Abstract

Ice cubes are one of the food products that are well known by the public and are considered safe for consumption. The Aim of this research is to see the contamination of Coliform bacteria and the presence of Escherichia coli in ice cubes. Test methods used include: Coliform test and identification of Escherichia coli bacteria. The results showed that 2 of the 6 positive samples contained Coliform bacteria and Escherichia coli bacteria with MPN values ​​above the safe limit. The conclusion of this study is that the ice cubes used by the perpetrators around the city of Karawang have microbiological quality that is not suitable for consumption by the public and does not comply with the microbiological quality requirements of the Indonesian National Standard 01-3839-1996 regarding ice cubes, namely the Total Coliform Bacteria exceeds 0/ 100mL.

Abstract

Research has been carried out on testing the quality of characteristics chitosan from cuttlefish bone waste with variations in deacetylation temperature. The purpose of this study is to identify the potential of cuttlefish bone as a raw material for producing chitosan and the effect of variations in deacetylation temperature on the quality of the chitosan. The tests of water content, ash content and chitosan solubility values. Solubility test showed that the three samples were soluble in 2% acetic acid. The results of the water content test with variations in deacetylation temperatures of 110 0C, 120 0C, 130 0C were 0.3467%, 0.1063% and 0.0135%, respectively. The ash content of chitosan is 0.2627%, 0.0125% and 0.0060%. The results of testing water and ash content showed a decrease in the value linear within increasing temperature.
