Buah mengkudu memiliki sejuta manfaat, dengan kandungan senyawa aktif berupa antrakuinon yang berfungsi untuk mencegah timbulnya kerutan pada kulit, serta berpotensi sebagai antibakteri. Pembuatan sabun padat transparan dari ekstrak buah mengkudu telah dilakukan dengan tujuan untuk mengetahui formulasi dan efektivitas sabun padat transparan dari ekstrak buah mengkudu sesuai SNI. Penelitian ini telah dilakukan dengan metode eksperimental yaitu tahap ke-1 proses pembuatan ekstrak buah mengkudu, tahap ke-2 pembuatan sabun padat transparan dengan konsentrasi F0 (0 g), F1 (0,1 g), F2 (0,3 g), F3 (0,6 g) dilakukan dengan metode hot process. Sabun yang dihasilkan disimpan (melewati proses curing) selama 2-3 minggu kemudian dilakukan uji kadar air, pH, stabilitas busa sabun, organoleptik, kadar alkali bebas, asam lemak bebas, dan aktivitas antibakteri. Berdasarkan hasil pengujian yang telah dilakukan menunjukkan nilai kadar air yang didapat yaitu F0 (18,93%), F1 (30,4%), F2 (28,86%), F3 (32%), nilai pH yang terbaik yaitu F3 (10,31), nilai stabilitas busa yang terbaik yaitu F2 (95,58%), hasil uji organoleptik sabun padat transparan memiliki aroma lavender dan tidak meninggalkan aroma buah mengkudu, kadar asam lemak bebas F0 (13,53%), F1 (10,9%), F2 (8,45%), F3 (5,45%), hasil uji aktivitas antibakteri menunjukkan 3 formulasi sabun padat transparan dari ekstrak buah mengkudu efektif menghambat aktivitas bakteri Staphylococcus aureus dengan konsentrasi F1 (8 mm), F2 (9 mm), F3 (8,6 mm). Berdasarkan hasil penelitian, dapat disimpulkan bahwa sabun padat transparan dari ekstrak buah mengkudu memiliki pH dan kadar alkali bebas sesuai SNI 3532:2021 dan efektif menghambat pertumbuhan bakteri S. aureus pada konsentrasi F2.

Noni fruit has a million benefits, containing active compounds in the form of anthraquinones which function to prevent the appearance of wrinkles on the skin, and has the potential to be antibacterial. Making transparent solid soap from noni fruit extract has been carried out with the aim of knowing the formulation and effectiveness of transparent solid soap from noni fruit extract according to SNI. This research was carried out using experimental methods, namely the 1st stage of the process of making noni fruit extract, the 2nd stage of making transparent solid soap with concentrations of F0 (0 g), F1 (0.1 g), F2 (0.3 g), F3 (0.6 g) was carried out using the hot process method. The resulting soap is stored (going through a curing process) for 2-3 weeks and then tested for water content, pH, soap foam stability, organoleptics, free alkali content, free fatty acids and antibacterial activity. Based on the results of tests that have been carried out, it shows that the water content values ​​obtained are F0 (18.93%), F1 (30.4%), F2 (28.86%), F3 (32%), the best pH value is F3 ( 10.31), the best foam stability value is F2 (95.58%), the organoleptic test results of transparent solid soap have a lavender aroma and do not leave a noni fruit aroma, the free fatty acid content is F0 (13.53%), F1 (10 .9%), F2 (8.45%), F3 (5.45%), antibacterial activity test results showed that 3 transparent solid soap formulations from noni fruit extract effectively inhibited the activity of Staphylococcus aureus bacteria with concentrations of F1 (8 mm), F2 (9mm), F3 (8.6mm). Based on the research results, it can be concluded that transparent solid soap from noni fruit extract has a pH and free alkali content according to SNI 3532:2021 and is effective in inhibiting the growth of S. aureus bacteria at F2 concentrations.
