Abstract

This study aims to: (1)Determine the effect of the addition of the element magnesium (Mg) in the aluminium casting on the level of hardness. (2) Determine the effect of the addition of the element magnesium (Mg) in the aluminium casting to micro structure. 3) Determine the effect of the addition of the element magnesium (Mg) in the aluminium casting on the level of impact strength. This study was descriptive research that clearly describes the results of experiments in the laboratory to some specimens. This method is implemented by providing independent variables intentionally to the object of study to know the effect on the dependent variable. The results showed three main things: (1) The more elements of magnesium (Mg) are added, the hardness value increased aluminium casting results.(2) The more elements of magnesium (Mg) is added, the grain size gets smaller aluminium casting results. (3) The more elements of magnesium (Mg) is added, then the impact strength aluminium casting results decline, but the decline is not too much.

Abstract

The objective of this research is to improve the learning completeness of the students in Grade XI O1 of PGRI Vocational High School 1 Surakarta through the application of the demonstration method in the competency standard of Conventional Ignition System Improvement.  This research used the classroom action research with two cycles. Each cycle consisted of four phases, namely: planning, implementation, observation, and reflection. The subjects of research were the students as many as 24 in Grade XI O1of the aforementioned school in Academic Year 2014/2015. The data of research were collected through observation sheet, documentation, and test. The data of research were analyzed by using the descriptive comparative model of analysis. The application of the demonstration method can improve the learning completeness on the competency standard of Conventional Ignition System Improvement of the students in Grade XI O1 of PGRI Vocational High School 1 of Surakarta in Academic Year 2014/2015. This result can be seen in the results of observations in the pre-cycle, Cycle I, and Cycle II. In the testing of learning result variable, the researcher used the content validity. The test was made by comparing between the contents of the instrument and the learning materials instructed. The content validity of the test was tested by using the expert judgment, and the test item application was tested by using Iteman 3.0. The result of the test was 20 valid items and 5 essays. In the pre-cycle, the percentage of the students who completed the learning is 62.5%, which is still far below the minimum learning completeness criterion of 80%. The percentages of the cognitive aspect learning completeness are 75% in Cycle I and 87.5% in Cycle II respectively of the minimum learning completeness criterion of 75, and the class completeness successfulness indicator is 80%. In the learning completeness of the affective aspect, there are several indicators, namely: (1) interest, (2) attitude, and (3) respect. The percentages of the affective aspect learning completeness are 76.03% in Cycle I and 88.87% in Cycle II respectively. The psychomotor learning completeness was measured with the practicum activities through work on job sheet aided with engine stand media of conventional ignition system. The result of practicum shows that the percentages of the learning completeness are 79.16% and 91.6% in Cycle II respectively. These results have fulfilled the benchmark of the students? learning completeness, namely: 80%.

Abstract

The objectives of this research are to get the successfulness: (1) in the improvement of the learning activeness in the Basic Welding subject matter of the students in Grade X M2 of PGRI Vocational High School 1 of Surakarta through the application of the cooperative learning model of the Jigsaw type; and (2) in the improvement of the learning achievement in the Basic Welding subject matter of the students in Grade X M2 of PGRI Vocational High School 1 of Surakarta through the application of the cooperative learning model of the Jigsaw type. This research used the classroom action research with two cycles. Each cycle consisted of four phases, namely: planning, implementation, observation, and reflection. The subjects of research were the students in Grade X Machinery 2 of the aforementioned school. The sources of research data were observation sheet on the learning activeness and the test of achievement. The data of research were collected through test i.e. written test items non-test i.e. students? learning activeness observation sheet during the implementation. They were validated through content validity for the data obtained through test and construct validity for the data obtained through non-test. The result of research shows that the application of the cooperative learning model of the Jigsaw type can improve the students? learning activeness as indicated by the result of observation. Prior to the treatment, only one indicator of learning activeness fulfills the target. Following the treatment with the cooperative learning model of the Jigsaw type, 3 indicators fulfill the target in Cycle I, and all of the indicators fulfill the target in Cycle 2. Furthermore, the students? average score of learning achievement also improves. In the pre-cycle which uses the lecturing method, the completeness of the learning achievement is 41%. Following the treatment with the cooperative learning model of the Jigsaw type, it becomes 68% in Cycle I and 82% in Cycle II respectively. Thus the application of the cooperative learning model of the Jigsaw typecan improve the learning activeness and achievement in the Basic Welding subject matter of the students in Grade X Machinery 2 of PGRI Vocational High School 1 of Surakarta.

Abstract

This research is a Classroom Action Research which conducted in two cycles. Each cycle consists of planning, action, observation, and reflection stage. The research was conducted class XI Mechanical Engineering academic year 2014/2015. Data obtained through field observations, interviews, achievement test (pre-test cycle, the first cycle and second cycle) and documentation. This study uses comparative descriptive data analysis techniques. It shows that the implementation of cooperative learning model Think Pair Share (TPS) improves the student critical thinking skills and learning outcomes at class XI Mechanical Engineering academic year of 2014/2015 in the subjects of Lathe Machining. In the pre-cycle stage where conventional method was used, it is found that the critical thinking skills and learning outcomes is quite low. When the cooperative learning model Think Pair Share (TPS) was applied, the student critical thinking skills and student learning outcomes increase eventhough it was still under the research target of 70% on each of the indicators of critical thinking skills and a minimum of 70% of students completed the minimum mastery criteria (?75). The target value of critical thinking skills and learning outcomes in the second cycle until been reached the intended target. An increase in the percentage of students who passed the minimum mastery criteria of pre-cycle of 34.375% to 78.125% in the second cycle or an increase of 43.75%.
