Abstract

Burns result from exposure to heat sources like fire, chemicals, or radiation and can lead to tissue loss or damage. Traditional healing of burns often involves using herbal remedies like gotu kola and coconut, typically oil extracts. This study aims to identify the healing effects of burns by administering a combination of ethyl acetate extract of gotu kola herb and virgin coconut oil (VCO) to mice. The mice were divided into 7 groups, namely negative control (K(-)) was given tween 20; positive control (K(+)): burn topical medicine on the market, P1: 10% Ethylacetate extract in tween 20; P2: VCO; P3: Ethyl acetate extract 10% and VCO 50% in tween 20; P4: 5% Ethyl acetate extract in VCO; P5: extract 10% Ethyl acetate in VCO and treated for 21 consecutive days with a frequency of twice a day. The results showed that the combination of 10% ethyl acetate extract of gotu kola herb in VCO exhibited the highest healing activity for burns, comparable to the positive control (K(+)) topical medicine on the market. The higher the extract concentration and VCO, the better the healing activity of burns.

Abstract

The production of biomass-based briquettes from coconut shell charcoal and banana corm adhesive has been successfully carried out. This research aims to determine whether the banana corm may serve as an adhesive for briquette production from coconut shell charcoal. The concentration of banana corm utilized as adhesive is 10, 20, 30, 40, and 50%. For comparison analysis, this study also employed tapioca flour adhesive with the same concentration. The briquettes adhere to the SNI 01-6235-2000 standard for briquettes. The quality of briquettes is determined based on fixed carbon content and calorific value. The minimum standard calorific value and fixed carbon content are 5000 cal/g and 65%, respectively. Briquettes with a 90:10 ratio (coconut shell charcoal to banana corm adhesive ratio) had the highest calorific value of 7250 cal/g and fixed carbon content of 80.04%. In comparison, the tapioca flour adhesive provides a calorific value and fixed carbon content of 6995 cal/g and 81.09%, respectively. Furthermore, another indicator that determines briquette quality is the content of moisture, ash, and volatile matter. Briquettes with a 90:10 ratio possessed low moisture content (3.55%), ash content (6.45%), volatile matter content (9.96%), and burning rate (0.020 g/sec). This result indicates that the briquettes with a 90:10 ratio exhibit the greatest quality. Briquettes with banana corms adhesive have similar characteristics to tapioca flour, especially in terms of calorific value. As a result, the highlight of this research lies in offering banana corm, which has scientific contribution and future potential as an alternative adhesive in the briquetting process
