Abstract

Palm Fatty Acid Distillate (PFAD) is a byproduct from palm oil processing industry that used as raw material for synthesis polyester based vegetable oil. The purpose of the research is to study polymerization reaction of ester from PFAD using inisiator benzoyl peroxide 0,4%. There are three step reaction in this research that was esterification, polymerization, and polyesterification. The esterification stage was done at temperature 70oC, reaction time 2 hours, reactant ratio 1:8 (ALSD : metanol), and concentration catalyst H2SO4 1% (w/w) ALSD. Polymerization stage was done at variation of temperature 120, 130, and 140oC and variation reaction time 3, 4, and 5 hours using initiator benzoyl peroxide 0,4% (w/w) methyl ester. Polyesterification stage was done at temperature 175-200oC, reaction time 4 hours, and ratio reactant 1:1 (polymerized methyl ester : ethylene glikol). Product was analyzed by using FT-IR, GC-MS, and viscosity. The result of FT-IR showed that vinyl group was presence who indicated double bonding was presence and polymerization was not occur. The result of GC-MS showed there had no change of molecular weight. And product with temperature 130oC and reaction time 5 hours has higher viscosity value.Keyword : benzoyl peroxide, esterification, PFAD, polymerization

The purpose of this study, i.e. to find out how big the influence of motive media use the LINE TODAY against user satisfaction on student, Faculty of social and political sciences of the University of Riau, where the audience is the research on college students by using the media LINE TODAY.The method used in this research is quantitative method of explanation , the data collection through questionnaires. The location of the research done in the environmental school of social and political sciences of the University of Riau. The number of samples in this research as much as 96 respondents. Withdrawal of samples using techniques unknown populations. To find out how big the influence both of these variables, the researchers used a simple linear regression analysis. For the processing of data is carried out using a questionnaire, the statistical program Product And Service Solution (SPSS) Windows version 23.Based on the results of a simple linear regression for this research, the regression coefficient values obtained in this study were Y = 2.860 + 0.917 with significance level of 0.0000 and smaller than α = 0.05. Whereas on the basis of test results obtained, the determination of 71.70%. That is, there is a strong influence among the motives of the use of the media LINE TODAY against user satisfaction on student, Faculty of social and political sciences of the University of Riau. While the rest of 28.30% are influenced by other indicators that are not included in this study, then it means that the Ha received Ho denied.Keywords: social media, LINE TODAY, motive, gratification, satisfaction
