ABSTRACT
One factor constituting a major concern for teachers to improve the quality of Machine Technology of vocational education is the student’s ability to solve problems so that they can understand and apply the concept comprehensibly and profoundly. Understanding concepts of Trigonometry comprehensibly and profoundly facilitates the vocational high school students learn other subjects such as engineering drawings that sustains manufacturing drawing techniques subjects, lathe machining engineering, milling machining techniques, and CNC machining techniques. One of the advantages of the process involving metacognition in mathematical problem solving is the development of strong and thorough understanding of the math problems. On the basis of this phenomenon, the researchers felt the need to examine more deeply about the profile of the metacognition of the Machine Technology vocational high school students with lower ability and field independent cognitive style in mathematical problem solving in particular trigonometry. The present study was explorative with qualitative approach. It was held at the Machine Technology Department of SMK Krian 1 (a vocational high school) of Sidoarjo.The main instrument in this study was the researchers themselves as human tools. The data analysis has started from the preparation of the study until after the data collection process was complete. The further data analysis was carried out into four stages: the categorization of data, data reduction, data presentation, drawing conclusions. The results
indicated that the students with poor field independent cognitive styles conducted very minimal metacognitive activity in problem solving trigonometry.

Abstract
Vocational senior high schools will have been cooperating by the year of 2020. They must adjust to the competencies of each region to achieve 60% of vocational high school and 40% of senior high school ratio. However,the fact shows that they have not met the required competencies since only 49% of vocational and 51% of senior high school ratio have been earned. The number of senior high schools will be minimized but vocational high school will be increased due to the consideration of the internal challenges in the year of 2020, in which the Indonesian population will overflow so that it needs efforts to use human resources especially those of productive age to be useful nor being burden for the national development. Thus, the way to achieve this aim is to transform human resources who have the competence and skills through education (rule of
government, number 70 in 2013). The design of this research is developmental research, which develop task to solve trigonometry problem. The model of teaching and learning sets developed in this research relates to modified 4-D models, consisting of ; to define,design, and develop.
Keywords: students‘ tasks on Trigonometry problems, development, Mathematical competence, cognitive style
