Industrial apprenticeship experience has not been realized optimally towards student work readiness. So that the process of factualization and comparing theoretical knowledge with actual situations and conditions in the world of work becomes less than optimal. In addition, students' work motivation to be ready to work is still in the low category. This study aims to reveal the effect of internship experience and work motivation on work readiness. The sampling technique used simple random sampling and obtained research respondents as many as 450 students in 5 vocational education schools in Yogyakarta. The combination of factor analysis and regression analysis was used to analyze the data using second-order PLS-SEM analysis. Convergent and discriminant validity, and internal consistency reliability has met the test requirements. Evaluation of the structural model shows the value of effect size (f2) with a large effect, the determination coefficient (R2) of the variable is 65.90%, and the predictive relevance (Q2) is 51.10%. Hypothesis testing is based on the β-coefficient, ρ-value, dan T-statistic values that have met the cut-off values suggested in the literature. So that all hypotheses Ha is accepted which indicates that there is a positive and significant effect on the internship experience and motivation on student work readiness. Schools are expected to provide encouragement for work motivation and review the apprenticeship process from planning to implementation in the field so as to increase student work readiness.

The purpose of this research is to determine the effect of twist drill angle variations and spindle rotational speed on the surface roughness of S45C steel in the drilling process. The method used in this research is the experimental method. The independent variables used in this study are variations in twist drill angle (118°, 122°, 125°) and spindle rotational speed variations (1036 rpm, 1340 rpm, 1630 rpm). The dependent variable used is the result of surface roughness in S45C steel. While the control variable used is a feed rate of 0.18 mm/round. The results showed the highest surface roughness was obtained at 125° twist drill angle variation and spindle rotational speed of 1630 rpm with a roughness value of 8.590 µm, while the lowest surface roughness value was obtained at 118° twist drill angle variation and spindle rotational speed of 1036 rpm with a roughness value of 2.898 µm. This research can be developed to find standards from other aspects that affect the results of the drilling process.

This study aims to: (1) identify problems of management of facilities and infrastructure practices of the automotive engineering department at Muhammadiyah Gamping Vocational School, (2) find the causes of problems management facilities and infrastructure practices of the automotive engineering department at Muhammadiyah Gamping Vocational School, and (3) formulate solutions to solve problems facility management and infrastructure practices majoring in automotive engineering at Muhammadiyah Gamping Vocational School. This research was conducted in March 2020. This research is a descriptive research using questionnaires and interviews to retrieve data. The population in this study were: (1) the principal, (2) the vice principal in the field of facilities and infrastructure, (3) the head of expertise competence, (4) the head of the workshop, and (5) the technician/toolman. Data analysis techniques using descriptive analysis techniques. The results showed that: (1) Problems that exist in the management of facilities and infrastructure practices of the automotive engineering department at Muhammadiyah Gamping Vocational School : (a) lack of motivation to work, (b) facilities and infrastructure are not well organized, (c) taste lacking, (d) low work discipline, and (d) low technical competence; (2) the causes of problems that occur include: (a) educational qualifications that are not appropriate, (b) do not have relevant expertise certificates, (c) there is no education and training that is in line with expectations; (3) an alternative solution that can be held is training of facilities and infrastructure managers in the practice of automotive majors at the Muhammadiyah Gamping Vocational School with competencies: (a) technical competence, (b) communication, and (c) workshop management.

This study aims to: (1) know competence test results of competency test participants in the Indonesian Automotive Profession Certification Body from Yogyakarta Special Region (DIY) in 2017 if reviewed from the certification scheme and (2) to know the distribution of competency unit of competency test participants causing competency test participants to be declared not yet competent in LSP Otomotif Indonesia from DIY in 2017 This research is a descriptive research. The subject in this research is 198 competency test participants. Technique of collecting data is documentation. This research uses quantitative analysis technique. The result of the research shows that: (1) the competency test results of competency test participants from the Special Region of Yogyakarta in Indonesian Automotive Profession Certification Body in 2017 if reviewed based on scheme 01 (Service & Maintenance 5000 KM Motorcycles) is 70% (70) participants are declared competent and 30% (30) participants are deemed incompetent (including high category). Furthermore, in scheme 02 (Service and Maintenance 10,000 Km of Conventional Light Vehicles) 75% (15) are competent and 25% (5) declared incompetent (including category and in scheme 03 (Service and Maintenance of 10,000 Km Light Vehicle Injection System) of 61.54% (48) participants are declared competent and 38.46% (30) declared not yet competent (including very low category), (2) the distribution of competency units shows that in scheme 01, competency unit that most competent participant is OTO.SM02.001.01 (Maintaining Engine with its Components) that is equal to 73.33%, in the scheme of 02 competency units that most participants are not competent are OTO.KR02.014.01 (Maintenance / Service of Gasoline Fuel System) and OTO.KR05.011.01 (Fixing Ignition System) that is equal to 100% , whereas in the scheme of 03 competency unit that most participants are not competent is OTO.KR05.012.01 (Maintaining / Servicing and Improving Engine Management system) that is equal to 76.67%.
