Daftar Isi:
- Indonesia especially west Kalimantan well known by its biodiversity. one of the potential resource is Kesum leaves. Kesum leaves are potential as antibacterial effect, so it can be formulated into pharmaceutical dosage form, especially gel. This research aimed to know the best comparison between Carbopol 940 and Hydroxypropyl methylcellulose (HPMC) gel base affecting the physical stability of methanol extract and fraction of kesum leaves gel by Simplex Lattice Design (SLD) method. Gels were prepared into three variation base such as gel A (100% Carbopol - 0% HPMC); gel B (0% Carbopol - 100% HPMC); and gel C (50% Carbopol – 50% HPMC). According to SLD method, the optimum combination obtained among the basis were 100% Carbopol - 0% HPMC for Kesum leaves methanol extract gel and 10% Carbopol – 90% HPMC for Kesum leaves methanol fraction gel. Gel that was formulated were tested their physical stability, including adhesive ability, spreadability and pH. The results were analyzed using One sample t- test and was known there was no difference of the physical stability between Kesum leaves methanol extract gel and Kesum leaves methanol fraction gel.
