The purpose of this research is to conduct an empirical study to analyze the influence of the aspects related to the application of the blended learning approach and individual student characteristics, especially origin school, on learning outcomes of Lathe Machining. This research is a Quasi Experiment using the Treatment by Level design. The research data analysis was conducted using 2-way ANOVA with one treatment variable and one attribute variable. This research was conducted at the Machining Workshop, Department of Mechanical Education, Faculty of Engineering, Universitas Negeri Yogyakarta. The results of this study indicate; 1) The learning outcomes of students who take learning using the Blended Learning approach are higher than students who take learning using the conventional approach; 2) There is an interaction effect between the learning approach and the origin of the school on learning outcomes of Lathe Machining; 3) The learning outcomes of students from vocational high schools who take blended learning approach are higher than students from vocational schools who take conventional approaches; 4) The learning outcomes of senior high school students who take learning with the blended learning approach are not different from those from vocational high school students who take the conventional approach.

The needs of operators for each type of industry are different because the type and the complexity of the task is different. Small and medium-sized industries require machine operators with better capabilities than operators in large companies, thus it is necessary to identify what tasks are performed by these operators. This study aim at (1) identifying duties of machine tool operators in small and medium enterprises, and (2) identifying tasks carried out by machine tool operators in small and medium enterprises. This study used a descriptive research method. The participants were eight machine tool operators from five small and medium enterprises in Yogyakarta, Indonesia. The data collection used document review, observation, questionnaires and focus group discussions. The data were analysed using descriptive analysis. The results of the study were (1) five duties done by machine tool operators are identified (maintaining safe work environment, maintaining the machine tools, analyzing the blueprint, performing machining operations, cleaning the machines and the workplace), and (2) twenty seven tasks executed by machine tool operators are identified; twenty-two knowledge and skills, seventeen behaviors, and eighteen machines, tools and equipment required by machine operators.
