This study aims to strengthen students’ networking competencies through the implementation of straight and cross LAN cable assembly training at SMKN 53 Jakarta. The background of this research is based on the need to enhance students’ practical skills in basic computer networking, particularly in understanding cable configurations and applying crimping techniques according to industry standards. Many students experience difficulties in differentiating wiring standards and applying correct crimping procedures, which impacts their readiness for industry practice. This research employed a practical training approach combined with demonstration and hands-on methods. The participants were students of the Computer and Network Engineering program. Data were collected through observation, performance assessment, and competency tests before and after the implementation. The findings indicate a significant improvement in students’ understanding of cable color standards (T568A and T568B), accuracy in assembling straight and cross cables, and testing results using LAN testers. Students demonstrated higher levels of technical accuracy, problem-solving skills, and work discipline after the intervention. The implementation of structured practical activities proved effective as a medium for strengthening networking competencies. The study implies that continuous practice-based learning aligned with industry standards is essential in vocational education to improve students’ technical readiness and employability in the networking field.

The increasingly rapid aviation industry demands the world of work to have quality human resources, the demand for higher performance requires a workforce with academic qualifications and employability  to be said to be feasible. The College of Aerospace Technology provides a field work practice program where cadets will face challenges and various obstacles in the new work environment, therefore employability skills are needed that can affect the performance given during the field work practice period. This study aims to analyze the influence of employability skills on the performance of cadets in field work practice, as well as to identify how much influence employability skills have on the performance of cadets in field work practices. This study uses a quantitative method, the research was conducted at Sekolah Tinggi Teknologi Kedirgantaraan as the location for sampling students os the D4 Air Transport Management study program, and the research was carried out from September to May 2025 with the number of cadets of the D4 Air Transportation Management of the College of Aerospace Technology as many as 188 cadets. The data collection technique in this study used questionnaires, interviews and documentation. The data analysis technique used normality tests, simple linear regression tests, T tests and determination efficiency tests. The results of the study showed that there was a significant influence of employability skills on the performance of cadets practicing field work, with a score of Thitung > Ttabel (18,671 > 1,973) and an Rsquare value of 65.2% so that it can be said that Ha was accepted. Suggestions for future researchers are expected to develop this study by adding other variables related to cadets' performance during fieldwork practices by expanding the population coverage.
