Abstract

Rendahnya kreativitas dan kedisiplinan siswa dapat berdampak pada kurang efektifnya pelaksanaan praktik kerja lapangan. Oleh karena itu,    perlu evaluasi praktik kerja lapangan untuk mengetahui hasil belajar siswa. Penelitian ini bertujuan untuk mengevaluasi pelaksananaan Program PKL. Evaluasi PKL tersebut dilihat dari aspek context, input, process, product yang dihadapi dalam pelaksanaan program PKL. Metode penelitian yang digunakan yaitu metode kombinasi desain equental Explanatory dengan menggabungkan metode penelitian kuantitatif menggunakan angket/kuesioner dan kualitatif dengan wawancara secara berurutan. Teknik analisis data menggunakan persentase tingkat capaian responden (uji TCR) untuk data kuantitatif dan data kualitatif dianalisis menggunakan teknik analisis data Miles dan Huberman yaitu: data reduction, data display dan conclusion/verification. Hasil Penelitian menunjukkan bahwa pelaksanaan evaluasi context memperoleh standar skor rata-rata 83,00% dengan kategori baik. Evaluasi input memperoleh standar skor rata-rata 78,96% dengan kategori cukup. Evaluasi Process memperoleh standar skor rata-rata 68,94% dengan kategori cukup. Evaluasi product memperoleh standar skor rata-rata 77,89% dengan kategori cukup. Maka, program PKL 79,09% masih dalam kategori cukup dan perlu diperbaiki dari berbagai aspek, sehingga bisa tercapainya tujuan dari PKL sebagai praktik kerja industri.

Abstract

The efficiency of vehicle exhaust systems is critical for reducing backpressure and emissions, enhancing performance and sustainability of harvesting energy. This study investigates the effect of an additional body modification at the exhaust tip on pressure and velocity distributions using Computational Fluid Dynamics (CFD) simulations in SolidWorks. Simulations were conducted at inlet velocities of 10, 15, and 20 m/s. Results show that the modified design does not increase backpressure, with the maximum observed change being a minor reduction of 0.137% at 20 m/s. These findings confirm that the additional body can be safely integrated without adversely affecting engine performance, while also improving downstream flow uniformity. This supports its viability for use in energy harvesting systems and highlights its relevance for sustainable exhaust system development.

Abstract

The manual management of teacher journals, agendas, and student attendance in Indonesian vocational schools (SMK) often limits real-time information access for parents, resulting in one-way communication and limited academic transparency. This study aimed to develop and evaluate DIJAGA, a mobile-based academic information system integrating teacher journals, student attendance, and parental monitoring. The Research and Development (R&D) method using the ADDIE model was employed. The study involved one media expert, two content experts, 43 teachers, 124 parents, and attendance data from 180 students. Data were collected through expert validation, practicality and effectiveness questionnaires, and a one-group pretest-posttest attendance assessment. The results showed high validity, with mean Aiken's V values of 0.833 for media and 0.816 for content. DIJAGA was considered practical by 95% of teachers and 91% of parents, while the effectiveness score reached 80.41%. Student attendance increased from 87.22% to 92.05%, with a significant paired-samples t-test result, t(179) = 6.975, p < .05. The N-Gain score was 0.378 (moderate), and Cohen's d was 0.520 (moderate). These findings indicate that DIJAGA is a valid, practical, and potentially effective system for improving academic transparency, parental trust, communication, and student attendance. However, because the study used a one-group pretest-posttest design without a comparison group, the findings should be interpreted as exploratory evidence of feasibility rather than definitive causal evidence.
