THE EFFECTIVENESS IMPLEMENTATION OF JOB SHEET TO ENGINEERING PRACTICAL LEARNING AT SMK MA’ARIF SALAM MAGELANG
THE EFFECTIVENESS IMPLEMENTATION OF JOB SHEET TO ENGINEERING PRACTICAL LEARNING AT SMK MA’ARIF SALAM MAGELANG By: Wahyu Isti Nugroho 09503241022 ABSTRACT This study was aimed to find out: (1)The students’ learning achievement toward the engineering practical learning of lathe by implementing the job sheet developed as practical guidelines; (2)The students’ learning achievement toward the engineering practical learning of lathe by implementing the previous job sheet; (3)Difference of the students’ learning achievement between students who implement previous job sheet and those who implement developed job sheet as the engineering practical learning of XI class SMK Ma’arif Salam Magelang; (4)Effectiveness implementation developed job sheet in the engineering practical learning of XI class SMK Ma’arif Salam Magelang. This study was employed quasi-experimental design with non-equivalent control group design. The variables of this research were independent variable (the implementation of the developed job sheet) and dependent variable (students’ achievement which is in the forms of students’ job grade and students’ working attitude). The population was the total number of class XI SMK Ma’arif Salam Magelang divided into three groups while the sample used in this study consisted of two groups with XI MA class (control group) and XI MB class (experimental group). This study employed purposive sampling technique in which the sample was selected under certain consideration. The data collection techniques were used the pretest-posttest result and observation toward students’ working attitude. The instrument validity of this study used content validity done by consulting the instrument to the expert (expert judgment). Then, the data were analyzed by using t-test. The findings revealed class who implement developed job sheet increasingly achieved toward the enginering practical learning of lathe and student’s working attitude as standard operational procedur and K3(after receiving the treatment). Results of classrom learning using previous job sheet there is not a significant improvement. This showed that the the posttest score resulted from t-test between control and experimental group got -38.385 with df = 74 with the level of erroneous of 0.05. Then, it was achieved Sig. (2-tailed) of 0,000 which was less than the level of erroneous of 0.05. Thus, this means that there was a significant difference toward the students’ engineering learning achievement between the students who implement previous job sheet and who implement job sheet developed. Comparison of the t-test score on the pretest-posttest between the control group and the experimental group was thitung=-80.891 with df = 37 and Sig.(2-tailed) = 0.000. The value of Sig. (2-tailed) was less than the significant level of 0.05. Therefore, the result of the t-test showed that the implementation of the job sheet developed was statistically effective as the guideline of the engineering practical learning for the students of SMK Ma’arif Salam Magelang.
