Abstract

The objectives of this research are to find: (1) the correlation between innovative attitude in Productive Subject Matter and lathe practice skill of the students in Grade XI of Mechanical Expertise Program of State Vocational High School 2 of Surakarta; (2) the correlation between cognitive strategy in Productive Subject Matter and lathe practice skill of the students in Grade XI of Mechanical Expertise Program of State Vocational High School 2 of Surakarta; and (3) the simultaneous correlation of innovative attitude and cognitive strategy in Productive Subject Matter to lathe practice skill of the students in Grade XI of Mechanical Expertise Program of State Vocational High School 2 of Surakarta. This research used the correlational method. Its population was all of the students as many as 127 in Grade XI of Mechanical Expertise Program of the aforementioned school. The samples of research were taken by using the simple random sampling technique and consisted of 92 students. The variables of research consisted of two independent variables i.e. innovative attitude and cognitive strategy and one dependent variable i.e. lathe practicum skill. The data of research were collected through questionnaire and documentation. The former was used to collect the data of innovative attitude and cognitive strategy, and the latter was used to collect the data of lathe practicum skill. Prior to its use, the questionnaire was tried out to 35 students. The data were validated by using the product moment formula, and their reliability was tested by using the Cronbach’s Alpha formula. Both the validity and reliability tests were aided with the program of SPSS Version 17.0. The data were analyzed by using the partial correlation analysis and the multiple linear regression analysis. Prior to the analyses, the data were exposed to pre-requisite tests of normality test, linearity test, and multicollinearity test. The results of research are as follows: (1) there is a positive and significant correlation between the innovative attitude and the lathe practice skill of the students in Grade XI of Mechanical Expertise Program of State Vocational High School 2 of Surakarta as indicated by the value of (r_count = 0.235 > that of r _table = 0.207 at the significance level of 5%), meaning that the proposed hypothesis is verified; (2) there is a positive and significant correlation between the cognitive strategy and the lathe practice skill of the students in Grade XI of Mechanical Expertise Program of State Vocational High School 2 of Surakarta as indicated by the value of (r_count = 0.208 > that of r_table = 0.207 at the significance level of 5%), indicating that the proposed hypothesis is verified; and (3) there is a simultaneously positive and significant correlation of the innovative attitude and the cognitive strategy to the lathe practice skill of the students in Grade XI of Mechanical Expertise Program of State Vocational High School 2 of Surakarta as indicated by the value of (r_count = 0.235 > r_table = 0.207 at the significance level of 5%), meaning that the proposed hypothesis is verified  as indicated by the value of (R_y12 = 0.256 with the value of F_count =3.112 > that of F_table = 1.433 at the significance level of 5%), meaning that the proposed hypothesis is verified. The effective contribution of the innovative attitude variable to the lathe practicum skill is 5.58%, whereas that of the cognitive strategy variable to the lathe practice skill is 4.92%, meaning that the two variables have effective contributions to the lathe practicum skill as much as 10.8%, whereas the other factors, which are not explained in this research contribute to it as much as 89.2%. The correlational model of X₁ and X₂ to Y is Y = 87,762 + 0,252 X₁ +0,237 X₂. This model is statistically significant.
