Abstrak Penggunaan gel hand sanitizer saat ini menjadi jalan keluar untuk menjaga kesehatan dan kebersihan tangan agar lebih praktis dan mudah dibawa. Penelitian ini bertujuan untuk menghasilkan antiseptik alami dari kombinasi ekstrak daun Miana dan Kemuning terhadap Staphylococcus aureus dan Escherichia coli dalam bentuk gel. Gel hand sanitizer dibuat dari kombinasi ekstrak daun miana dan kemuning yang menunjukkan daya hambat optimum terhadap bakteri Staphylococcus aureus dan Escherichia coli. Kombinasi ekstrak daun Miana dan Kemuning dibuat dalam 3 variasi konsentrasi (K1 = 5%: 15%), (K2 = 10%: 10%), dan (K3 = 15%: 5%). Formulasi gel hand sanitizer diuji kemampuannya sebagai antiseptik dan uji stabilitas fisik pada hari ke 0, hari ke 7, hari ke 14, hari ke 21, dan hari ke 28. Konsentrasi optimum dari kombinasi ekstrak daun miana dan kemuning sebagai antiseptik adalah pada kombinasi K3 = 15%: 5%. Kombinasi antiseptik alami K3 (NAK3) menunjukkan daya hambat sebesar 7,33 mm (terhadap Staphylococcus aureus) dan 09,00 mm (terhadap Escherichia coli) yang termasuk dalam kategori sedang. NAK3 memenuhi persyaratan untuk uji organoleptik, homogenitas, pH, kemampuan menyebar, dan adhesi, serta stabil selama penyimpanan..  Kata kunci: antiseptik, miana, kemuning, gel, hand sanitizer Abstract The use of hand sanitizer gel is currently a more practical and portable way to maintain health and hand hygiene. This study aims to generate a natural antiseptic from a combination of Miana and Kemuning leaves extract toward Staphylococcus aureus and Escherichia coli in gel formulation. The hand sanitizer gel is made from a combination of Miana and Kemuning leaves extract which shows optimum inhibition against Staphylococcus aureus and Escherichia coli bacteria. The combination of Miana and Kemuning leaves extracts was made in 3 variations of concentration (K1 = 5%: 15%), (K2 = 10%: 10%), and (K3 = 15%: 5%). The hand sanitizer gel formulation tested its ability as an antiseptic and on physical stability test on day 0, day 7, day 14, day 21, and day 28. The optimum concentration of the combination of Miana and Kemuning leaves extracts as an antiseptic is at a combination of K3 = 15%: 5%. The combination K3 Natural Antiseptic (NAK3) showed an inhibitory power of 7.33 mm (against Staphylococcus aureus) and 09.00 mm (against Escherichia coli) which was included in the moderate category. The NAK3 meets the requirements for organoleptic tests, homogeneity, pH, spreadability, and adhesion, and is stable during storage. Keywords: antiseptic, miana, kemuning, gel, hand sanitizer
