Abstract

The 21st century is characterized by rapid developments in information technology and automation, with many routine and repetitive jobs being replaced by machines, both production and computers. The world of his technical and vocational education curriculum in the 21st century is full of challenges to face. Technical education and vocational education must be able to create learning that is able to make students have the competencies needed by the world of work in the 21st century. Technological developments make changes in economic, social culture and including education. This article aims to examine the competencies needed in the 21st century and how effective learning is for this century. The research was conducted using the literature review method. In the 21st century, the world of work is increasingly complex, graduate students from technical education and vocational education must have learning skills, literacy skills and life skills. Skill competencies taught to students must focus on one particular area, because in the world of work each worker will only do one type of work. Learning in technical and vocational education is recommended to use the application of the project-based learning model. Various research results have found that this model is able to make students have the skills needed in this 21st century.

Abstract

Stone chisels produced by blacksmiths which are made using leaf spring steel are often too brittle or fragile so that when they are used, they often occur in the form of cracks and breaks. This study aims to determine the appropriate hardness level for stone chisels. The process is carried out by comparing the hardness level of stone chisels that have been used but still in good condition and those that have been damaged. Broken stone chisels have a high adequate hardness compared to good stone chisels so that damaged stone chisels can be reconditioned to get the right rock chisel hardness. Heat treatment is given to damaged stone chisels to improve the hardness level by normalizing the process to restore the initial mechanical properties of the steel and increasing the hardness of the chisel by heating the steel and then quenching it using water cooling media. Based on the experimental process carried out that the hardness level of a good stone chisel is between 228 HB to 320 HB by heating the duan spring steel to a temperature of 780ºC with a hold time of 10 minutes then cooling it quickly using water and stone chisels can break when it is used because it has a very high hardness.

Abstract

Development of Computer Laboratory Management Information System at SMKS Pertiwi Batam is an application to support the performance of related institutions. Lack of data collection and the absence of supporting applications and data that is still stored in the form of archives and computers manually. Information systems are designed based on websites using the codeigniter programming language and MySQL database. While the development of the research system uses the waterfall method with the stages of requirements, design, implementation, verification, and maintenance. This information system serves as a means of sharing information about the inventory of computer laboratory equipment, the use of computer laboratories, and schedules regarding the use of computer laboratories. With this information system, the agency will be easier in collecting inventory data, using and scheduling computer laboratories. As well as the need to make monthly reports on computer laboratory data.
