Abstract

Bioethanol is produced with raw materials containing starch plant or carbohydrates (rice,  maize, tubers, etc.) and cellulosic materials (wood, agricultural waste), conducted through the conversion of carbohydrates into sugar (glucose) with the fermentation process by microorganisms. Bioethanol can be made as solvents, perfume ingredients, flavourings, food dyes and medications, even can be made as alternative fuels. Bioethanol production is done by the hidrolysis and fermentation or frequently called to SHF process (Separated Hydrolysis and Fermentation). Cellulose and hemiscellulose  to be used is sourced from palm fiber waste. The goal of this study is to obtain the effect of time of inoculation inoculum and also get the optimum concentration of  bioethanol in the manufacture of bioethanol from palm fruits fiber waste. Stages of the purification process starts from pretreatment, delignification with ash extract TKS and purification with hydrogen Peroxide (H2O2). After the purification process, the next stage is hidrolysis process with sulfur acid (H2SO4  2M). Hidrolysis was done at a temperature of 100 oC and a reaction time about 3 hours to get the initial glucose. The effect of inoculum time to be done in this study by the variaion of time 24, 48, 60 and 72 hours. Number of cells for the inoculum  will be analyzed with spectrophotometer by observing optical density (OD). Fermentation process will take place during 4,5 days (108 hours) by the variation of time 12, 24, 48, 72, 96 and 108 hours with the help of  Saccharomyces cerevisiae. The result showed that the best time of inoculum occurred at 60 hours with OD 0,882 with time of  fermentation at 96 hours which got the concentration of bioethanol 6 v/v (47,34 gr/L). Keywords: bioethanol, fermentation, hidrolysis, inoculum, palm fiber, Saccharomyces  cerevisiae

Abstract

The study aims to analyse the impact of the use of Activity Based Costing (ABC) on Micro, Small Medium Enterprises. The population in this study were manufacturing Micro, Small and Medium Enterprises located in Bulukerto District, Wonogiri Regency with a total of 200 manufacturing MSMEs. The sampling technique in this study used probability sampling and random sampling technique. The sample in this study stated 133 manufacturing SMEs in calculating the sample size using Slovin Sampling. The type of data in this study is quantitative, while the data source comes from primary data obtained from the result of the questionnaire. In this study, the data analysis technique used was Partial Least Squares (PLS) 3.0. The result of this indicate that on Activity Based Costing (ABC) variable has a direct effect on operational performance, the Activity Based Costing (ABC) variable has a direct effect on financial performance, the operational performance variable has a direct effect on financial performance, Activity Based Costing (ABC) on financial performance through operational performance has a direct effect, this effect can be seen in the original sample which shows positive result, the T-statistic and P-values shows significant result. In the mediation test, Activity Based Costing (ABC) through operational performance has no effect on financial performance, because in direct and indirect relationship it has the same result, namely positive and significant. So in the mediation test, the presence or absence of operational performance variables doest not affect Activity Based Costing (ABC) on financial performance.
