Penelitian ini dilakukan di Kota Banda Aceh dengan mengambil sampel masyarakat Kota Banda Aceh yang terkena pajak penghasilan. Model analisis yang digunakan adalah regressi probit Hasil akhir estimasi menunjukan bahwa hanya variabel jumlah anggota keluarga yang berpengaruh positif dan signifikan terhadap wilingness to pay leisure time akibat kenaikan pajak penghasilan masyarakat Kota Banda Aceh. Adapaun nilai odds ratio 2,037 lebih besar mau membayar untuk waktu senggang untuk setiap kenaikan 1 jiwa anggota keluarga. Dari hasil estimasi diketahui semakin banyak jumlah anggota keluarga maka semakin besar dampak pajak penghasilan terhadap wilingness to pay leisure time.

The co-solvent used are tetrahydrofuran and hexane. The experimental result shows that the transesterification rate was improved when compared to the system without cosolvents. The biodiesel produced in the experiment was analyzed by gas chromatography-mass spectrometry (GC-MS), which showed that methyl oleate was the highest compound in biodiesel.

A two-step pretreatment of degumming and esterification was conducted to prepare UFO as raw material for transesterification. The esterification and transesterification was performed by using ethanol as solvent in the presence of ultrasonic irradiations operating at frequency of 40 kHz. The esterification was carried out with oil to ethanol ratio of 1:10, temperature of 60oC and reaction time of 4 hours in the presence of 1 wt .% H2SO4 as an acid catalyst. Meanwhile, the transesterification reaction was carried out with oil to ethanol molar ratio of 1:8, 1:10, 1:12, 1:15; KOH catalyst concentration of 0.5, 0.75, 1, 1.25 and 1.5 wt.%; and reaction temperature of 40, 50 and 60oC. The highest biodiesel yield of 65% obtained at ultrasound-assisted transesterification condition of oil to ethanol molar ratio of 1:12, reaction temperature of 50oC and KOH concentration of 1 wt.%. The results of analysis of some parameters of the product showed biodiesel has fulfilled the specifications according to the Indonesian National Standard (SNI) 04-7182-2006 number.Keywords: Biodiesel, Esterification, Used frying oil, Transesterification, Ultrasonic Format The file format, physical medium, or dimensions of the resource application/pdf Identifier An unambiguous reference to the resource within a given context http://jurnal.unsyiah.ac.id/RKL/article/view/239 Language A language of the resource eng Publisher An entity responsible for making the resource available Chemical Engineering Department, Syiah Kuala University, Banda Aceh, Indonesia Relation A related resource http://jurnal.unsyiah.ac.id/RKL/article/view/239/225 Source A related resource from which the described resource is derived Jurnal Rekayasa Kimia & Lingkungan; Vol 8, No 1 (2011): Jurnal Rekayasa Kimia & Lingkungan 2356-1661 1412-5064 Title A name given to the resource Penggunaan Ultrasonik untuk Transesterifikasi Minyak Goreng Bekas Type The nature or genre of the resource info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Peer-reviewed Article Contributor An entity responsible for making contributions to the resource Dublin Core The Dublin Core metadata element set is common to all Omeka records, including items, files, and collections.

Creator An entity primarily responsible for making the resource Supardan, Muhammad Dani Satriana, Satriana Date A point or period of time associated with an event in the lifecycle of the resource 2006-06-01 Description An account of the resource Biodiesel has been shown to be the best substitute for fossil-based fuels to its environmental advantages and renewable resource availability. There is a great demand for the commercialization of biodiesel production, which in turn calls for a technically and economically reactor technology. The production of biodiesel in existing batch and continuous-flow processes requires excess alcohol, typically 100%, over the stoichiometric molar requirement in order to drive the chemical reaction to completion. In this study, a novel reactor system using a reactive distillation (RD) technique was discussed for biodiesel production. RD is a chemical unit operation in which chemical reactions and separations occur simultaneously in one unit. It is an effective alternative to the classical combination of reactor and separation units especially when involving reversible or consecutive chemical reactions such as transesterication process in biodiesel production.

In this study, a relationship between water losses with frying time during vacuum frying process of potato chips has been developed. A first order kinetic model was used, in which drying rate constant is a function of the main process variables, i.e. oil temperature, sample thickness and vacuum pressure. The experimental data of Garayo and Moreira (2000) have been used to validate the model. Generally there was a good agreement between the calculated results and the experimental data. Then, the effect of initial water content and vacuum pressure has been studied.Keywords: kinetic model, potato, vacuum frying, water loss Format The file format, physical medium, or dimensions of the resource application/pdf Identifier An unambiguous reference to the resource within a given context http://jurnal.unsyiah.ac.id/RKL/article/view/1078 Language A language of the resource eng Publisher An entity responsible for making the resource available Chemical Engineering Department, Syiah Kuala University, Banda Aceh, Indonesia Relation A related resource http://jurnal.unsyiah.ac.id/RKL/article/view/1078/1011 Source A related resource from which the described resource is derived Jurnal Rekayasa Kimia & Lingkungan; Vol 6, No 2 (2007): Jurnal Rekayasa Kimia & Lingkungan; 82-86 2356-1661 1412-5064 Title A name given to the resource Prediction of Water Loss During Potato Vacuum Frying Process Type The nature or genre of the resource info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Peer-reviewed Article Contributor An entity responsible for making contributions to the resource Dublin Core The Dublin Core metadata element set is common to all Omeka records, including items, files, and collections.

In this work, the effects of the main variables involved in the esterification process i.e. alcohol to oil molar ratio, reaction temperature, agitation speed and the initial amount of FFA of oil, were studied in the presence of sulphuric acid as catalyst at concentration of 1%-w. The experimental results show that the esterification process could lead to a practical and cost effective FFA removal unit in front of typical oil transesterification for biodiesel production.Keywords: CPO off grade, esterification, free fatty acid Format The file format, physical medium, or dimensions of the resource application/pdf Identifier An unambiguous reference to the resource within a given context http://jurnal.unsyiah.ac.id/RKL/article/view/76 Language A language of the resource eng Publisher An entity responsible for making the resource available Chemical Engineering Department, Syiah Kuala University, Banda Aceh, Indonesia Relation A related resource http://jurnal.unsyiah.ac.id/RKL/article/view/76/71 Source A related resource from which the described resource is derived Jurnal Rekayasa Kimia & Lingkungan; Vol 7, No 2 (2009): Jurnal Rekayasa Kimia & Lingkungan 2356-1661 1412-5064 Title A name given to the resource Esterification of Free Fatty Acid in Crude Palm Oil Off Grade Type The nature or genre of the resource info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Peer-reviewed Article Contributor An entity responsible for making contributions to the resource Dublin Core The Dublin Core metadata element set is common to all Omeka records, including items, files, and collections.
