The preliminary research about soft skills of graduated students from vocational high school that took mechanical as their major were not optimal at work place. It could be proven and interaction that were done by graduated students from mechanical engineering at work. The objective of this research was to identify specific soft skills that are importan to be taught to mechanical engineering students of vocational high schools. Dacum Approach was used in this research.The sample of this research was 50 industry employees who have specification in mechanical engineering, vocational high school teachers who teach mechanical engineering and experts in soft skill field. A questionnaire was used to identify soft skills needed, with the options are very important, important, not important, and very not important. Based on the analysis of data obtained can be concluded that 67% of the sample said that soft skills are very important, 31% are important and 2 % are not important. The result of this research could be used as an important information to develop vocational high school curriculum and to develop a soft skills learning model for mechanical engineering students at vocational high schools.

This study aims at developing the augmented reality application technology, a complementary learning on graphic design to face the skills and learning of the industrial revolution 4.0. This study uses a 4D (four-D) development method for the development of augmented reality application technology and uses a survey method for validity. This AR application will be validated by 12 experts, while the respondents used in filling out the needs analysis questionnaire at the define stage (four-D) are students and lecturers of Informatics Engineering Education, Padang State University. The results of this study indicate that on the analysis of the achievement of the learning process, it can be seen that there are still expectations and advantages in the achievement of the learning process desired by lecturers and students, where the learning process is still in the sufficient category and 80%, students need development of technology as complement reality to be used as learning media in the learning process. The validation test also shows that the augmented reality application technology is included in the valid category with an average value of V value of 0.933. So, it cannot be denied that the augmented reality application technology is valid to be used in the learning process.

OCR (Optical Character Recognition) adalah suatu solusi yang efektif untuk proses konversi dokumen cetak ke dokumen digital. Permasalahan yang timbul dalam proses pengenalan dokumen komputer adalah bagaimana teknik pengenalan untuk mengidentifikasi berbagai jenis karakter dengan berbagai ukuran dan bentuk. Metode pengenalan yang digunakan dalam tugas akhir ini adalah metode Template Matching Correlation. Sebelum proses pengenalan, citra masukan dengan format * bmp atau jpg * diolah terlebih dahulu di proses preprocessing, yang meliputi binerisasi, segmentasi, dan normalisasi gambar. Rata-rata tingkat keberhasilan pengenalan yang dihasilkan oleh sistem ini adalah 92,90%. Hasil akhir menunjukkan bahwa penggunaan metode Template Matching Correlation cukup untuk membangun sebuah sistem OCR dengan akurasi yang baik efektif.

The low absorption of the workforce in the vocational high school graduates indicates their lack of expertise and competency. It urges to improve their work skills to meet the demand of work. This research aims at developing a Lean-based learning model to enhance the work skills of vocational high school students. This research categorized as development research uses the modified Borg and Gall method. The Lean-based learning model was tested through three stages, namely its validity, effectiveness and practicality. Respondents of the research are vocational high school students, vocational high school teachers and industry practitioners in Indonesia. The model was validated by some experts and FGD results. The effectiveness of the model was tested by an experimental with a posttest only control group design. The population of the experiment was students of the Vocational High School who were doing an industrial experience in some industries, which followed a work shadowing strategy, the sample is chosen by random sampling; data were collected to develop a performance test. Two questionnaires were used to evaluate the practicability of the model according to the perceptions of the teachers and students of the Vocational High School. Based on the research, the developed learning model can be categorized as "good" in case of its validity, effectiveness, and practicality. It means that the lean-based learning model is valid, effective and practical. The conclusion of research is that lean learning model is one of the alternatives to improve work skills competency among vocational high school students to fulfill the industrial demand.
