Abstract

Many factors influence the low number of skilled vocational high school graduates. One factor that is the leading cause is the lack of instruments that can be used in the learning process, especially authentic instruments, to assess students' abilities in the psychomotor domain. Students who are dominant in the cognitive sphere are not necessarily skilled in the psychomotor realm, especially when using the equipment and making improvements to the brake system. The purpose of this study is to develop an assessment instrument that is appropriate to be used by the teacher in evaluating the psychomotor domain's abilities, specifically for the brake system competency. This research is development research that uses ADDIE models as a reference for research. ADDIE model has five stages of development that need to be considered, including analysis; (2) design; (3) development; (4) implementations; and (5) evaluation. Based on the results of the analysis and discussion of the psychomotor domain assessment instrument for the competency of the brake system that was developed to be suitable for use in the learning process. Feasibility is proven from the results of the validation of experts who get an assessment of 4.66 with a very valid category. The instrument reliability test results that get the Cronbach's alpha value of 0.895, and the value of inter-observer reliability is 0.740. In addition, the instrument is also practical when used in the learning process. This was evidenced by the acquisition of practicality test value of 3.31 and entered in the practical category.

Abstract

The density and viscosity of vegetable oil are higher than that of diesel oil. Thus its direct combustion in the diesel engine results many problems. This research was conducted to investigate the flame characteristics of combustion of jatropha curcas lin in pure, hydrolyzed and methyl ester form. The results indicated that the combustion of pure jatropha curcas lin occurs in three stages, hydrolyzed in two stages    and methyl ester in one stage. For pure jatropha curcas lin, in the first stage, unsaturated fatty acid burned for  0.265 s.  It is followed by saturated fatty acid, burned for 0.389 s in the second stage. And, in the last stage is the burned of glycerol for 0.560 s. Meanwhile for hydrolyzed one, in the first stage, unsaturated fatty acid burned for 0.736 s, followed by saturated fatty acid, burned  for 0.326 s in the second stage. And the last, for methyl ester is the burned for 0.712 s. The highest burning rate was for methyl ester which was 0.003931cc/s. The energy releasing rate of methyl ester, which was for 13,628.67 kcal/(kg.s) resembled that of diesel oil the most, while the lowest rate was for pure jatropha curcas lin which was 8,200.94 kcal/(kg.s). In addition, massive explosion occurred in the fuel containing unsaturated fatty acid and glycerol
