Palm oil is one of the fatty oil can used as the oil phase in the microemulsion system. The purpose of this research was to identify the effect of increasing concentration of combination of surfactant and cosurfactant on the physical stability of palm oil microemulsion. This oil was formulated into microemulsion system by increasing concentration of combination of tween 80 and sorbitol (1:1) in various concentrations, which were 54%, 56%, 58% and 60% as surfactant and cosurfactant component. The evaluation included organoleptic, viscosity test, pH, density, surface tension and particle size and zeta potential test. The pH showed in the range 5.8 to 6.4. Viscosity value obtained between 637.47 to 808.20 Cps. Density measurement were between 1.1123 to 1.1235 g/ml. The results of surface tension obtained between 39.76 to 43.07 dynes/cm. The results of particle size measurement results obtained from 21.27 to 23.97 nm and the zeta potential between −10.28 to −18.03. It can be concluded that the increasing of concentration of surfactant and cosurfactant can improve physical stability of the microemulsion.
Pemilihan kemasan merupakan salah satu pengembangan produk yang dapat dilakukan untuk dapat meningkatkan harga jual dari suatu produk dan merupakan salah satu upaya yang dapat dilakukan dalam mempertahankan mutu, keamanan dan khasiat dari suatu produk selama masa penyimpanan dan penggunaan. Edukasi mengenai pemilihan kemasan merupakan salah satu program pembinaan lanjutan yang dilaksanakan di Lembaga Pembinaan Khusus Anak (LPKA) II Bandung. Pada kegiatan ini peserta terdiri atas 18 anak didik lapas (andikpas) yang berusia dibawah 18 tahun. Selain materi mengenai pemilihan kemasan, peserta juga diberikan workshop berupa cara pembuatan sabun cair sari nanas dan pembuatan label kemasan produk kosmetik. Pencapaian target luaran dinilai dengan membandingkan rata-rata nilai pretest dan posttest yang diperoleh oleh peserta. Hasil yang diperoleh menunjukkan terjadi peningkatan rata-rata nilai posttest bila dibandingkan nilai pretest, namun tidak terdapat perbedaan bermakna (sig 2-tailed > 0,0005) yang menunjukkan tidak ada pengaruh pemberian materi dan workshop pada anak didik LPKA II Bandung.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
