Abstract

Collagen gives a moist state on the wound area to accelerate the wound healing process. Chitosan is a polymer as known as non-toxic, antibacterial, antifungal, biodegradable, and biocompatible materials. Combination of collagen and chitosan expected to be the best biomaterials as a wound dressing for the healing process. The study aimed to determine cytotoxicity assay on collagen-chitosan wound dressing sterilized by ultraviolet (UV) Light using Brine Shrimp Lethality Test (BSLT) method. The test groups were divided into K0, K1, K2, and K3 groups. K0 contained pure chitosan as a control group, K1 contained collagen 25%-chitosan 75%, K2 contained collagen 50%-chitosan 50%, K3 contained collagen 75%-Chitosan 25%. Collagen extracted from skin and scalp of snakehead fish (Channa striata) then mixed with chitosan until formed collagen-chitosan wound dressing. This study used Brine Shrimp Level Test (BSLT) method with solution concentration 10, 50, 100, 250, 500, 750 and 1000 ppm. Based on the results showed that K0, K1, K2, and K3 group had LC50 >1000 that proven collagen-chitosan wound dressing was non-toxic materials. As conclusion of the study explained composite wound dressing based on collagen-chitosan in all groups that sterilized under UV-Light along 15 minutes was not toxic based on Brine Shrimp Lethality Test showed LC50 >1000.

Abstract

Crystal violet and Safranin are dyes in Gram staining, which are carcinogenic. Alternative safe materials are needed to minimize the use of carcinogenic properties. Purple sweet potato (Ipomoea batatas L.) peels were the candidate of the alternative dye source because of its high anthocyanin pigment. The purpose of this study was to determine purple sweet potato (Ipomoea batatas L.) peels extract as an alternative to Gentian violet in Gram staining of bacteria. Extracts obtained from purple sweet potato peels studied with varying concentrations of 50%, 60%, and 75% for 1, 3, and 5 min as a substitute for Gentian violet on Bacillus sp. The parameters observed from this study based on visual field clarity, glass slide cleanliness, contrast, bacterial shape, bacterial colour. Each extract concentration compared with a control group using Gentian violet. The results showed that optimum staining in 50% concentration for 5 min, 60% concentration for 5 min, 75% concentration for 3 min, and 5 min respectively. The present study exhibited the potency of Ipomoea batatas L. peels extract as an alternative staining agent.

Abstract

Escherichia coli is the bacteria that can cause diarrhea in humans and often used as a parameter of stool environmental pollution. Culture of E. coli from the sample often requires Mac Conkey as commercial media which is able to distinguish it from other bacteria in the Enterobacteriaceae group. Commercial media such as Mac Conkey certainly has a price that is quite expensive because of its ability as a growth medium for Enterobacteriaceae. Therefore, in the study tested natural ingredients that can be used for growth media, such as coconut water. The purpose of this study was to compare the ability of Mac Conkey media and coconut water to support the growth of E. coli. This research is an experimental study with a completely randomized design. The concentration of coconut water tested was 0%, 20%, 40%, 60%, 80%, and 100%. The results showed that at the concentration of coconut water 20% to 60% the number of E. coli colonies on coconut water media was slightly below the Mac Conkey Agar media, while in coconut water a concentration of 80% showed a greater number of colonies than Mac Conkey. The Mann Whitney test showed a significant difference between the number of colonies on 80% coconut water media and Mac Conkey Agar, which was equal to 0.004 (p < 0.05). Based on these results, coconut water has the potential to be used as a growth medium for E. coli.
