Puspita, Tika (2019) Optimasi Kombinasi Pelarut Terhadap Formulasi Sabun Cair Transparan Menggunakan Metode Simplex Lattice Design Dengan Penambahan Minyak Pepermin (Mentha Piperita L.) Dan Minyak Lavender (Lavandula, L.) Sebagai Antibakteri. Sarjana thesis, Universitas Brawijaya.
Abstract
Optimasi sabun transparan dapat menghasilkam komposisi agen transparan yang tepat. Sabun antibakteri umumnya digunakan sebagai produk pembersih, tetapi masih banyak produk sabun antibakteri di pasaran yang menggunakan bahan antibakteri sintetis. Zat antibakteri alami alternatif dapat digunakan dengan menambahkan minyak atsiri antimikroba seperti minyak peppermin dan minyak lavender. Tujuan dari penelitian ini adalah untuk menentukan proporsi optimal pelarut sabun cair transparan dan untuk menentukan aktivitas antibakteri pertumbuhan S. aureus. Pelarut yang dioptimalkan terdiri dari etanol, gliserin, dan gula cair. Respon yang diteliti meliputi transparansi, viskositas, pH, dan total asam lemak. Rancangan formula diaplikasikan dari metode Simplex Lattice Design (SLD) yang terdiri dari 13 formula. Evaluasi karakteristik sabun yang optimal terdiri dari uji organoleptik, alkali bebas, bobot jenis, kekuatan busa, dan aktivitas antibakteri. Hasil penelitian menunjukkan bahwa komposisi pelarut optimal terdiri dari 20% gula cair, 18% etanol, dan 18% gliserin. Nilai rata-rata respon transparansi, viskositas, pH, dan total asam lemak masing-masing adalah 98,3%, 553,33 cP, 10,04 dan 19,85%. Evaluasi karakteristik sabun optimum menunjukkan nilai alkali bebas 0,12±0,015%, bobot jenis 1,161 g/ml, daya busa 1,05±0,050 cm, dan zona hambat pertumbuhan S. aureus 10,17±2,753 mm.
English Abstract
Optimization of transparent soap can obtain the proper composition of the transparent agent. Antibacterial soaps were used as cleaning products, but there are still many antibacterial soap products on the market that used synthetic antibacterial substances. Alternative natural antibacterial substances can be used by adding antimicrobial essential oils such as peppermint oil and lavender oil. The purpose of this study was to determine the optimum proportion of transparent liquid soap solubilizers and to determine the antibacterial activity of S. aureus growth. The optimized solubilizers consisted of ethanol, glycerin, and liquid sugar. The studied responses included transparency, viscosity, pH, and total fatty acids. The formula design was applied from the Simplex Lattice Design (SLD) method which consisted of 13 formulas. Evaluation of optimal soap characteristics consisted of organoleptic, free alkali, specific gravity, foam power, and antibacterial activity. The results showed that the optimum solubilizer composition consisted of 20% liquid sugar, 18% ethanol, and 18% glycerin. The average value of transparency, viscosity, pH, and total fatty acids responses were 98,3%, 553,33 cP, 10,04 and 19,85%, respectively. Evaluation of optimum soap characteristics showed the value of free alkali value 0,12±0,015%, specific gravity 1,161 g/ml, foam power 1,05±0,050 cm, and inhibition growth zone of S. aureus 10,17±2,753 mm.
