Abstract

This research is an experimental study, in which the researcher designed the design, then formed into aprototype weld oxy Acetylin that will be used in the practice of welding practicum. The research subject is amechanical engineering student of 2015 as many as 19 students.The results of the research showed that the building of the design of welding (OAW) Oxy Acetylin Weldingfueled Acetylin Gas works well and can increase the learning interest of mechanical engineering students onwelding courses at the University of Hasyim Asy'ari Tebuireng Jombang, this can be seen from severalindicators of interest that become judgment. The liking indicator shows a value of 77.63%, expressed interest inthe liking indicators including the high category. For interest indicators obtained 75.00% value. expressedinterest in interest indicators including high category. While the analysis results for the focusing indicator is81.58%. This expressed interest in the focused indicator including the very high category. For the activeindicators students obtained a value of 66.78%. This expressed interest in the student's active indicatorsincluding high category. Then the confidence indicator values of 80.53%. This expresses interest in theconfidence indicator including the high category. Keywords: students, welding processes, welding acetylin, learning interests

Abstract

The need for measuring the mechanical properties of material in the Material Science course makes thecharpy impact machine to be immediately presented to be a supporting tool as well as a reference forstudents in carrying out impact testing. The purpose of this study was to find out how to design and createa charpy impact machine, find out how to work and analyze performance based on the impact energyreceived by the specimen and find out the impact on student learning interest in the Materials Sciencecourse. This research is a design research that ultimately produces a product. The performance of the tooluses ten steel specimens with dimensions of 10mm x 10 mm x 55 mm indicating an average impact priceof 1,509601 J / mm2. The measurement results of the learning interest questionnaire showed an indicatorof student interest in the presence of the charpy impact testing machine in the materials science course at73.68%..Keywords: design, impact, charpy, learning interest

Abstract

The research is to examine the performance of solar cell with turmeric andindigo dye. Turmeric dye is obtained by extraction method while the indigo dye is obtained by fermentation method from indigofera plants. Indigofera and turmeric dyes were treated by mixing dye with indigo / turmeric molarity 0.32M / 0.23M. Characteristics of the dye are studied. The natural dye was tested with absorbance test, FTIR and cyclic voltammetry. The dye mixing was then applied to dye-sensitized solar cells (DSSCs) and then DSSC performance was tested at 0 hours. The UV-Vis results showed that the dye absorption with indigo / turmeric molarity was 0.32M / 0.23M with an absorption peak of 375 -525 nm. From the FTIR test, the dyeing function mixing group with indigo / turmeric molarity of 0.32M / 0.23M is -OH, C = Caromatic, alkane C-H, amina C-N.The result of cyclic voltammetry test showed that mixing dye with indigo / turmeric molarity 0,32M / 0,23M band gap 0,745 eV. Result from this research of solar cellefficiency is 0.038%.
