Abstract

Karudin Tarmizi is a figure who has fought in the PRRI era. He is a PRRI figure in Padang Pariaman District. The PRRI lasted from 1958 to 1961. He began the PRRI struggle at the age of 31 years. The guerrilla struggle made him far from the family he loved. This Padang Pariaman Regency, especially in the Sicincin area, is a base for the defense of the central army and also the PKI. The PRRI upheavel in Padanng Pariaman District occurred in this Sicincin area. Karudin Tarmizi and his other colleagues began their struggle from the Kudu area because this area was a very safe area at that time. And the struggle ended in the Sikabu area. This study uses a historical method consisting of four stages namely; First, heuristics which means finding or gathering sources. Second, criticizing sources, namely the sources that have been collected both in the form of objects, written sources and oral sources are then verified or tested through a series of criticism, both internal and external. Third, interpretation namely the historical facts that have been collected have not told much. These facts must be compiled and combined with each other so as to form the story of historical events. Fourth, historiography is the final stage of historical research. The writing of this biography is expected to add to the literacy and knowladge of the community about PRRI figures, especially in Padang Pariaman District.

Abstract

Palm oil is one of the vegetable oils that can be used as diesel fuel (biodiesel) through a transesterification reaction with alcohol assisted in the form of a solid acid catalyst (activated carbon). Solid acid catalyst can be made from cassava skin carbon by being hydrolyzed to produce carbon at 250 oC. Next the carbon is sulfonated chemically with 98% H2SO4 solution. In this research, biodiesel was made through a transesterification reaction between bimoli and methanol oil with a ratio of 6: 1, and using a catalyst with sulfonation variation of 2 hours, 4 hours, 6 hours, and 8 hours. The reaction lasts 65 oC and takes 2 hours. The properties of solid acid catalysts were identified using FTIR and XRD. The results of FTIR spectra characterization show that at wave number 1100-1200 cm-1 there is a group O = S = O which is covalently bonded with the carbon structure in each sample of SCCP. The results of the maximum percentage of sulfonate fraction are located at 6 hours of sulfonation time using XRF. The results of biodiesel obtained were tested for physical properties such as density, flow rate and acid number. Keywords—Solid acid catalyst, cassava peel, sulfonated carbon, biodiesel.
