Abstract

The purpose of this study is to determine the relationship between K3 knowledge and OSH behavior by students of the Light Vehicle Engineering Department of Smk N 1 Tumpaan. The method used is a quantitative method with a correlational approach, assisted by the IBM SPSS version 22 analysis tool. The sample in this study amounted to 32 students. The results of this study indicate that there is a strong relationship between K3 knowledge and K3 behavior when practicing light vehicles with a large relationship of (r) = 0.683, K3 knowledge mastered by students must be improved, because there are still students who get the medium category, students' OSH behavior needs to be improved. maintained by the way the teacher must monitor continuously so that students continue to be disciplined in applying K3 principles during work

Abstract

Mild steel is steel with a concentration of carbon element below 0.3%. In its use as an oil storage tank material on fuel transport trucks, there is a problem, namely its resistance to corrosion in fuel. Sulfur compounds in fuel have a role in the formation of corrosion. Currently, the Ni-Cr electroplating coating method is very widely used as an effort to control the corrosion rate of carbon steel. The use of Ni-Cr as an anode is relied upon as a substance resistant to corrosion. Therefore, the purpose of this study was to identify how layer thickness affects corrosion levels in SS400 mild steel based on current variations and duration of the electroplating process. In this study using mild steel SS400 JIS G3101 with electroplating method (electroplating) varying the electric current 1A, 2A and 3A, as well as electroplating time of 10 minutes, 20 minutes and 30 minutes. The test parameters of the electroplating results are the actual layer thickness test, theoretical thickness test and corrosion rate test. Data processing was analyzed using two-way variance analysis. The thickness of the layer increases with increasing electric current and the length of time of Ni-Cr electroplating. The highest thickness value of 102.34 μm using a digital microscope while for theoretical testing of 98.33 μm, both were obtained at a current variation of 3A and an electroplating time of 30 minutes. The trend of corrosion rate value will decrease with the increase in electric current and the length of electroplating time with the lowest value of 0.003359 mmpy at a variation of electric current 3A and electroplating time of 30 minutes. For optimal values with the lowest corrosion rate on mild steel SS400 JIS G3101 as an oil storage tank material on fuel transport trucks, it is obtained by using a current of 3A and an electroplating time of 30 minutes Ni-Cr.

Abstract

The development of human resources in an effort to improve the quality of vocational secondary education in Indonesia is very important for recognizing the competence of graduates. This research aims to analyze human resource development, especially training and development at vocational schools. Qualitative case studies are used to obtain data and information. In-depth interviews and observations were carried out at SMK Negeri 2 Manado which had not yet become a center of excellence and SMK Negeri 5 which had become a center of excellence (SMK-PK). The research results show that human resource development, especially training and development, has a positive impact on the abilities of teachers. The aim is solely to improve the quality of graduates so that they suit the needs of the industrial world. Both schools have planned and implemented training and development to improve the abilities of educators. They need development so that there is a match between graduate competencies and the needs of the business world and the industrial world. Knowledge and skills develop along with technological developments and job demands. The training and development carried out by these two vocational education institutions is mostly a program offered by the government because it is related to funding.

Abstract

Abstrak— Pembelajaran jarak jauh yang tertata baik adalah yang menggunakan learning management system (LMS). LMS tidak hanya bermanfaat sebagai pembelajaran jarak jauh di masa pandemi Covid 19, tetapi juga untuk aplikasi blended learning dalam kondisi normal. Ada banyak platform LMS, tapi yang sering digunakan sekarang oleh dosen adalah Moodle dan Google Classroom. Kemampuan mereka dalam menangani LMS memengaruhi keefektifan pengajaran mereka. Setiap platform LMS berbeda dalam hal antarmuka pengguna dan fungsionalitas yang dapat diakses. Dosen butuh pengetahuan dan waktu untuk menguasai penggunaan LMS. Latar belakang pendidikan dan usia dosen memiliki pengaruh terhadap kemampuan mereka dalam menggunakan aplikasi LMS. Jadi, jenis platform LMS, tingkat pendidikan, dan usia dosen semuanya memengaruhi kesuksesan instruksional. Penelitian ini bertujuan untuk melihat pengaruh dan perbandingan antara ketiga kelompok tersebut. Kelompok platform LMS meliputi Moodle dan Google Classroom, kelompok kualifikasi pendidikan meliputi gelar master dan doktor, dan kelompok usia meliputi mereka yang berusia di bawah 45 tahun dan mereka yang berusia di atas 45 tahun. Penelitian menggunakan Anova 3-jalur yang mengungkapkan bahwa ketiga kelompok tersebut memiliki efek interaksi sebesar 74,1% terhadap keberhasilan instruksi mereka.

Abstract

In this era of globalization, which is very competitive in various fields of life, vocational education is crucial, considering the increasing demands for human resources in the labor market for middle-class workers. This study aims to determine the implementation of human resource development carried out by schools and to produce a draft of a human resource development model based on the Knowledge-Based View. This study uses a qualitative approach with a case study method. This method is used to obtain needs analysis data in designing a human resource development model in the field of vocational education. The findings of this study indicate that the development of educational resources, more specifically human resources in the education and training elements of the school, has been planned. In addition, it was also found that the development of educational resources, more specifically human resources in the career development element, has several requirements, including work period, credit points, work performance, education and training, and staff development. This study concludes that human resource development in State Vocational High Schools in Manado City has been implemented from planning to implementation.
