Effect Collagen Concentration Tilapia Scales on the Quality of Burn Ointment

Collagen is one of the main connective tissue animal proteins and has been widely used as a biomedical material. Collagen is divided into XIX types. Type I collagen, among others, is obtained from bone, scales and skin. Collagen derived from type I can repair tissue or accelerate tissue regeneration to heal burns. The purpose of this research was to determine the addition of fish scale collagen extract to the characteristics of the burn ointment preparation in accordance with the Indonesian National Standard (SNI) and the best quality. The method used in this research is an experimental method of Completely Randomized Design (CRD) consisting of 4 collagen addition treatments: 0%, 2%, 4% and 6% repeated 5 times. Parameters in this method include physical-chemical parameters (pH, spreadability, shelf life and homogeneity) and organoleptic parameters (appearance, aroma, texture and color). Bayes test results, the concentration of the addition of tilapia scale collagen in the ointment preparation of 4% resulted in a value close to the control treatment. The addition of 4% collagen was the best treatment compared to 2% and 6% with a pH value of 6.12, dispersion of 3.22 cm, safe ointment preparation did not change at all during 28 days of storage. Based on the results of the organoleptic test parameters, the ointment at this concentration had a homogeneous appearance, slightly yellowish white color, a distinctive smell of collagen and a semi-solid texture, this was in accordance with the quality standard of the ointment and had the best quality characteristics.
