<![CDATA[ABSTRAK Telah dilakukan penelitian mengenai formulasi sediaan sabun mandi cair dengan zat aktif ekstrak daun kumis kucing (Orthosiphon aristatus (Bl) Miq) dengan berbagai variasi konsentrasi basis Virgin Coconut Oil (VCO). Penelitian ini bertujuan untuk membuat formula sabun mandi cair ekstrak daun kumis kucing yang sesuai kriteria Standar Nasional Indonesia (SNI) 06-4085-1996. Pengujian terhadap sediaan sabun mandi cair disesuaikan dengan syarat ketentuan SNI dengan beberapa tambahan, pengujian-pengujian tersebut meliputi organoleptik, pH, alkali bebas, bobot jenis, cemaran mikroba, viskositas, stabilitas busa, aktivitas antibakteri sediaan serta uji hedonik. Hasil menunjukan bahwa Formula III memenuhi syarat SNI ksementara untuk Formula I dan Formula II memenuhi syarat SNI kecuali pada pengujian bobot jenis. Pada pengujian aktivitas antibakteri, Formula I menghasilkan zona hambat sebesar 7 mm ± 0,25, Formula II menghasilkan zona hambat sebesar 7,2 mm ± 0,34, dan Formula III menghasilkan zona hambat sebesar7,9 mm ± 0,25, sementara untuk sediaan pembanding yaitu Nuvo® menghasilkan zona hambat sebesar 8,9 mm ± 0,20. Hasil akhir menunjukkan bahwa sediaan sabun mandi cair ekstrak daun kumis kucing yang paling baik secara kimia, fisika, mikrobiologi dan sesuai dengan SNI adalah Formula III. Kata kunci : Sabun mandi cair, kumis kucing (Orthosiphon aristatus (Bl) Miq), VCO, zona hambat. ABSTRACT It has been researched on the formulation of liquid soap with active substances from leaf extract of kidney tea (Orthosiphon aristatus (Bl) Miq) with various concentrations of Virgin Coconut Oil (VCO) base. The aim of this study was to create a liquid soap formula from extract leaves kidney tea that fulfill the criteria of Indonesian National Standard (SNI) 06-4085-1996. Tests on liquid soap dosage adapted to the requirements of SNI with some additional conditions, the tests were including: organoleptic, pH level, free alkali levels, specific gravity, microbial contamination, viscosity, foam stability, antibacterial activity as well as the preparation of hedonic test. Results showed that Formula III fulfill the SNI criterias, while Formula I and Formula II also fulfill the SNI criteria, except the specific gravity testing. In the antibacterial activity testing, Formula I showed the inhibition zone of 7 mm ± 0.25, Formula II of 7.2 mm ± 0.34, and Formula III of 7,9 mm ± 0.25, while for the comparative preparations Nuvo® showed of 8.9 mm ± 0.20. The final result showed that the most stable liquid soap extract kidney tea leaf either in chemistry, physics, microbiology properties and fulfilled the SNI criterias was Formula III. Keywords : liquid bath soap, kidney tea (Orthosiphon aristatus (Bl) Miq), VCO, inhibition zone]]>
