Daun Lidah mertua (Sansevieria trifasciata Prain) diketahui mengandung senyawa polifenol, flavonoid dan saponin yang merupakan agen antibakteri. Lidah mertua memiliki aktivitas antibakteri terhadap Staphylococcus aureus dan Escherichia coli. Penelitian ini bertujuan untuk mengetahui konsentrasi ekstrak daun lidah mertua dalam sediaan gel yang memiliki aktivitas antibakteri terbesar dalam penurunan jumlah angka kuman. Ekstraksi daun lidah mertua menggunakan metode maserasi dengan pelarut etanol 96%. Variasi konsentrasi ekstrak daun lidah mertua dalam sediaan gel hand sanitizer yang digunakan yaitu F1 (10%), F2 (15%) dan F3 (20%). Na CMC digunakan sebagai gelling agent dalam formulasi. Sediaan gel hand sanitizer daun lidah mertua diuji aktivitas antibakteri terhadap Escherichia coli menggunakan metode difusi sumuran, sifat fisik (organoleptik, homogenitas, pH, viskositas, daya sebar dan daya lekat) serta penurunan jumlah angka kuman dengan metode swabbing. Hasil uji aktivitas antibakteri gel hand sanitizer ekstrak daun lidah mertua memiliki zona hambat bakteri terhadap Escherichia coli pada F1, F2 dan F3 berturut-turut sebesar 7,33 mm, 8,67 mm dan 9,75 mm. Hasil evaluasi sifat fisik gel daun lidah mertua memenuhi kriteria gel yang baik, namun memiliki daya lekat kurang 1 detik. Hasil penurunan jumlah angka kuman gel hand sanitizer daun lidah mertua paling besar pada F3 sebesar 52%. Namun, analisa statistik dengan Anova One Way menunjukkan bahwa F1 (32%), F2 (35%) dan F3 (52%) tidak menunjukkan perbedaan yang signifikan dalam penurunan jumlah angka kuman. Berdasarkan hasil penelitian ini dapat disimpulkan gel hand sanitizer ekstrak daun lidah mertua memiliki kemampuan dalam menurunkan angka kuman dan dapat digunakan sebagai alternatif sebagai sediaan gel hand sanitizer.

Lidah Mertua leaves (Sansevieria trifasciata Prain) are known to contain polyphenols, flavonoids, and saponins which have antibacterial activity. Lidah Mertua leaves have antibacterial activity against Staphylococcus aureus and Escherichia coli. This study aimed to determine the concentration of Lidah Mertua leaves extract in a gel dosage form which showed the highest antibacterial activity in decreasing germ numbers. Lidah Mertua leaves extract was prepared using the maceration method with ethanol 96%. There was a various concentration of Lidah Mertua leaves extract in gel hand sanitizer, these include F1 (10%), F2 (15%) and F3 (20%). Na CMC is used as a gelling agent in the formulation. The evaluation of the antibacterial activity of hand sanitizer gel leaves was performed against Escherichia coli using disc diffusion method, meanwhile physical properties (organoleptic, homogeneity, pH, viscosity, dispersion and adhesion) and a decrease in the germ numbers were determined by swabbing method. The results of the antibacterial evaluation of gel hand sanitizer activity showed that lidah Mertua leaves extract had a bacterial inhibition zone against Escherichia coli in F1, F2 and F3 of 7.33 mm, 8.67 mm and 9.75 mm respectively. The results of the evaluation of the physical properties of the lidah mertua leaves extract showed that the gel met criteria of a good gel, but had adhesion less than 1 second. The highest activity in decreasing term number was shown in gel hand sanitizer of lidah mertua leaves extract at F3 which was 52%. However, statistical analysis using Anova One Way showed that F1 (32%), F2 (35%) and F3 (52%) did not show a significant difference in decreasing germ numbers. Based on the results of this study, it can be concluded that the hand sanitizer gel from the extract of lidah mertua leaves has the ability to reduce the number of germs and can be used as an alternative as a gel hand sanitizer dosage form
