Microemulsions have thermodynamics and stable kinetics as carriers of ?-tocopherol compounds. This study aimed to know the effect of mixtures ratio of three nonionic surfactants and stiring time on the characteristics of ?-tocopherol microemulsion, as well as to obtain the best stiring time and mixture ratio of three nonionic surfactants to produce ?-tocopherol microemulsion. This experiment used a randomized block design with two factors. The first factor is the ratio of a mixture of three nonionic surfactants with Hydrophilic-Lipophilic Balance (HLB) 14.5. The second factor is stirring time. Data were analyzed using analysis of variance and continued with BNJ test. Test the effectiveness index to determine the best treatment. The results showed that the comparison of three surfactant mixtures, stirring duration and interaction between treatments significantly affected the characteristics of ?-tocopherol microemulsion. Comparison of the mixture of three surfactants Tween 80: Span 80: Tween 20 (v / v%) HLB 14.5 consisting of F2 (89,5 : 5,5 : 5) and 4 minutes stirring time is the best treatment for the characteristics of ?-Tocopherol microemulsion.

Pelarut yang digunakan adalah etanol pada konsentrasi  50, 60 dan 70% dengan waktu pengadukan 30, 60 dan 90 menit. Penelitian ini menggunakan rancangan acak kelompok faktorial dengan dua faktor: konsentrasi pelarut dan waktu pengadukan selama ekstraksi tepung ubi talas. Konsentrasi pelarut yang digunakan untuk ekstraksi glukomanan terdiri dari 3 level, yaitu 50, 60 dan 70% (v / v). Waktu pengadukan selama ekstraksi terdiri dari tiga level, yaitu 30, 60 dan 90 menit. Parameter yang diamati adalah rendemen, kadar glukomanan, kadar pati dan kadar air. Penelitian ini terdiri dari 2 (dua) tahap, yaitu pembuatan glukomanan dari tepung ubi talas dan tahap kedua adalah hasil terbaik pada tahap satu yang akan digunakan sebagai bahan  edible  film buah segar. Hasil penelitian menunjukkan bahwa konsentrasi pelarut dan waktu pengadukan memiliki pengaruh yang sangat signifikan terhadap kadar glukomanan, kadar air dan interaksinya, tidak berpengaruh nyata terhadap kadar pati, rendemen glukomanan. Karakteristik terbaik glukomanan adalah perlakuan konsentrasi pelarut etanol 70% dan waktu pengadukan 90 menit dengan kadar glukomanan 60,166%; kadar pati 0,072%; kadar air 7,313% dan rendemen  9,320% untuk tepung talas.   The general objectives to be achieved from this study were: 1) to determine the effect of solvent concentration and stirring duration on the glucomannan character of Taro sweet potato flour produced; 2) to obtain glucomannan with the best characteristics of Taro sweet potato flour. The solvent used is ethanol at a concentration of 50, 60 and 70% with a stirring time of 30, 60 and 90 minutes. The study used a factorial randomized block design with two factors: solvent concentration and stirring time during the extraction of Taro sweet potato flour. The concentration of solvent used for glucomannan extraction consisted of 3 levels, namely 50, 60 and 70% (v / v). The duration of stirring during extraction consists of three levels, namely 30, 60 and 90 minutes. The parameters observed were the yield, glucomannan content, starch content, and water content. This study consisted of 2 (two) stages, namely the manufacture of glucomannan from Taro sweet potato flour and the second stage was the best result in stage one would be used as an edible film chart on fresh fruit. The results showed that solvent concentration and stirring time had a very significant effect on glucomannan content, water content, and interaction and did not significantly affect starch content, the yield of glucomannan Taro flour. The best characteristics of glucomannan were the treatment of 70% ethanol solvent concentration and stirring time of 90 minutes with glucomannan content of 60.116%; 0.072% starch content; moisture content 7.313% and 9.320% yield for Taro yam flour.

Body scrub cream is a semi-solid dosage form containing one or more dissolved or dispersed medicinal ingredients in suitable base ingredients and serves to smooth the body's skin and remove damaged skin cells with the help of scrub material. Oyong fiber (Luffa acutangula) is used as a scrubber material that is natural, biodegradable and inexpensive. The aim of this study to know the effect of the addition of oyong fiber powder and stirring time to the characteristics of body scrub cream and to determine the percentage of the addition of oyong fiber powder  and length of stirring to produce the best body scrub cream. This research uses factorial randomized block design with two factors. The first factor is the percentage of the addition of the Oyong fiber powder consisting of 3 levels namely 5, 7, 9 and 11% and the second factor is the stirring time consisting of 10, 15, and 20 minutes. Data were analyzed by analysis of variance and continued by Tukey's test. The results of the study showed that the addition loofah (Luffa acutangula) fiber powder addition and the stirring time very affected the pH, viscosity, spreadability power, adhesion power and overall acceptance of the body scrub cream. The interaction between the addition loofah (Luffa acutangula) fiber powder addition and the stirring time very affected the viscosity and the spreadability power.  Addition of 9% of loofah (Luffa acutangula) fiber powder and 20 minutes of the stirring time was the best treatment for body scrub cream with characteristics as follows: pH 4.60, viscosity 37600 cp, homogeny, spreadability power 4.6 cm, adhesion power 9.88 seconds, separation ratio=1 and overall acceptance 5,90 (rather like to like).
