Abstract

ABSTRAK Gel merupakan sediaan topikal setengah padat yang nyaman digunakan karena menciptakan lingkungan lembab, dingin dan daya serap yang baik pada kulit serta mudah dicuci dengan air. Gel ekstrak kulit buah pisang telah terbukti mampu mempercepat proses penyembuhan luka bakar melalui peningkatan ekspresi VEGF dan kolagen. Penelitian ini bertujuan mengevaluasi sifat fisik dan uji iritasi gel ekstrak kulit buah pisang. Desain penelitian menggunakan metode eksperimental. Sebanyak empat ekor kelinci, masing-masing kelinci diberi enam perlakuan (basis gel, gel do 12.5%, gel do 25%, gel do 50% dan bioplacenton). Penelitian ini terdiri dari 3 tahap, tahap pertama pembuatan ekstrak kulit buah pisang, tahap kedua formulasi sediaan gel, tahap ketiga evaluasi sifat fisik dan uji iritasi. Sifat fisik meliputi uji daya sebar, uji daya lekat dan uji pH. Uji iritasi dilakukan dengan mengamati iritasi berupa eritema dan edema selama 24 jam, 48 jam, dan 72 jam. Hasil penelitian menunjukkan daya sebar gel ekstrak berbeda bermakna dengan basis gel dan bioplasenton (p<0.05). Daya lekat gel ekstrak berbeda bermakna dengan basis gel (p<0.05). Uji pH gel ekstrak berbeda bermakna dengan basis gel (p<0.05). Uji iritasi menunjukkan tidak ada perbedaan yang bermakna (p>0.05) antar semua perlakuan. Hal ini menunjukkan bahwa kulit kelinci tidak terjadi eritema maupun edema. Kata kunci : gel, daya sebar, daya lekat, uji pH, uji iritasi ABSTRACT Gel is a semi-solid topical that is comfortable to use because it creates a moist, cold and good absorption environment on the skin. Gel of banana peel extract show the healing process of burns through increased VEGF and collagen expression. This study aims to evaluate the physical properties and irritation test. Research design used experimental methods. Four rabbits, each rabbit was given six treatments (base gel, 12.5%, 25%, 50% and bioplacenton). This study consisted of 3 stages, the first was the manufacture of banana peel extract, the second was gel preparation formulation, and the third was the evaluation of physical properties and irritation test. Physical properties included dispersion test, stickiness and pH. Irritation test was done by observing in the form of erythema and edema for 24 hours, 48 hours, and 72 hours. The results showed that the gel dispersion of the extract was significantly different with base gel and bioplasenton (p <0.05). Adhesion of gel extract was significantly different with gel basis (p <0.05). Test of gel extract pH was significantly different with gel basis (p <0.05). Irritation test showed no significant difference (p> 0.05) between all treatments. This shows that rabbit skin does not occur erythema or edema.
