Abstract

This research was to find out the results of the bending and torsional stiffness testing of the SALWA car according to Formula SAE 2021 regulations. The research method was by designing through Solidworks 2014 software. Testing of test specimens referred to Formula SAE 2021 regulations. The front impact test results produced max Von Mises 1046.921 MPA with a displacement of 8,540 mm; the rear impact test resulted in a max Von Mises of 222,529 MPa with a max displacement of 6.85 mm; and the side impact test resulted in max Von Mises Stress of 104.15 MPa with a max displacement of 9,116 mm. In the front torsional test, the max Von Misses Stress reached 135,266 MPa with a total max displacement of 4,844 mm. The rear torsional test had a max Von Mises Stress value of 147,144 MPa with a displacement of 5.51 mm. The feasibility test still found connection and construction placement errors, and there was a low Factor of Safety value. In conclusion, the construction of the SALWA Electric Car prototype frame is not in accordance with Formula SAE regulations.

Abstract

Penelitian ini bertujuan untuk mengetahui tentang pengaruh motivasi belajar dan pembelajaran daring terhadap keberhasilan prakerin peserta didik kelas XI Teknik Bisnis Sepeda Motor di SMK Dirgahayu. Penelitian ini merupakan penelitian kuantitatif. Jenis penelitian ini merupakan jenis ex post facto, karena pengumpulan data dilakukan setelah kejadian berlangsung yang dilakukan dengan motivasi belajar dan pembelajaran daring yang mencapai indikator keberhasilan. Hasil penelitian menunjukan bahwa melalui hasil penelitian dan analisis data, ex post facto dapat di simpulkan bahwa motivasi belajar berpengaruh positif terhadap hasil prakerin, pembelajaran daring juga sangat berpengaruh positif terhadap hasil prakerin, motivasi belajar dan pembelajaran daring secara bersama- sama memberikan pengaruh positif terhadap hasil prakerin peserta didik kelas XI Teknik Bisnis Sepeda Motor SMK Dirgahayu Kedungadem tahun pelajaran 2022/2023. Hal tersebut dapat dilihat dari adanya perhitungan 59.09% (78) responden kategori rendah, 40.91% responden kategori tinggi, 0% kategori rendah dari 132 peserta didik, 2 adanya perhitungan dalam kategori tinggi 0 peserta didik sedang 132 peserta didik rendah 0 peserta didik atau 132 (100%) mempunyai motivasi sedang dan berpengaruh positif.

Abstract

Strengthening career choices for vocational students is essential in preparing them to enter the world of work. Many studies highlighted the importance of career choices that are by the areas of expertise for vocational students and even examine the mechanism for strengthening their career choices. However, limited studies still focused on testing models for forming career choices by involving social support, career self-efficacy, and vocational identity in an integrative manner. Therefore, this study investigated the model of developing student career choices by applying for social support, career self-efficacy, and vocational identity. This study used structural equation modelling (SEM) analysis with Amos 18 software. The study results revealed that social support, career self-efficacy, and vocational identity factors directly influence vocational students’ career choices. In addition, career self-efficacy mediates the effect of social support on career choice. Finally, vocational identity moderates the interaction of the independent variables (social support and career self-efficacy) and the dependent variable (career choice). The results of this study provided important implications for lecturers to implement learning strategies that aim to strengthen vocational students’ career choices.

Abstract

Safety riding is a safe driving behavior that can help to avoid traffic accidents. The purpose of safety riding is to increase rider awareness of all possibilities that may occur while driving. The stages of implementing this activity include: 1) Program needs analysis, 2) Activity planning. There have been several preparations made including intensive coordination with related local residents, the location of the program activities, and the time of program implementation. Everything is done by making a schedule to facilitate the implementation of further activities., 3) Implementation of activities by exposing safety riding material about driving safely and comfortably. Based on the results that have been carried out from planning, implementation to evaluation, it can be stated that community service activities are going well. From the results of the user questionnaire 1) Mastery of resource materials with a percentage score of 87 percent, 2) Timeliness of activities with a percentage score of 85 percent, 3) Material utilization with a percentage score of 95 percent, and 4) Participant satisfaction with a percentage score of 97 percent. Likewise with the results of the questionnaire the response of the participants averaged more than 75 percent. This shows that the activity went very well and satisfied the participants

Abstract

This study was motivated by the low activeness and learning outcomes of students in the subject of Automotive Electrical Systems. The aim of the research was to improve the activeness and learning outcomes of Grade XI TKR 2 students at SMK Giripuro Sumpiuh through the implementation of the discovery learning model. This research was a Classroom Action Research (CAR) conducted in three cycles, each consisting of planning, implementation, observation, and reflection stages. The research subjects were 42 students, while the objects of the study included student activeness and learning outcomes. Data were analyzed using quantitative analysis techniques. The results showed an increase in student activeness, namely 52.38% in the first cycle, increasing to 64.29% in the second cycle, and reaching 74.79% in the third cycle. Learning outcomes also improved, with an average score of 47.62% in the first cycle, 64.29% in the second cycle, and 88.10% in the third cycle. Based on these findings, it can be concluded that the implementation of the discovery learning model can improve student activeness and learning outcomes in Automotive Electrical Systems for Grade XI TKR 2 students at SMK Giripuro Sumpiuh
