Abstract

Salah satu aspek penting dalam pemeliharaan kendaraan yang sering diabaikan oleh pemilik mobil adalah spooring dan balancing. Penelitian ini bertujuan untuk mengetahui pentingnya spooring dan balancing dalam menjaga kesetabilan kendaraan terkhusus pada implementasinya di PT. Tunas Mobilindo Perkasa. Penelitian ini merupakan penelitian deskriptif dengan  pendekatan kualitatif. Proses pengumpulan data dilakukan melalui wawancara tertulis kepada dua kelompok responden, yaitu mekanik dan pelanggan yang pernah menggunakan layanan spooring dan balancing. Selain wawancara proses pengumpulan data juga melalui observasi. Metode ini bertujuan untuk memperoleh perspektif dari kedua belah pihak untuk memberikan gambaran yang komprehensif. Hasil penelitian menunjukkan bahwa spooring dan balancing sangat penting untuk menjaga kesetabilan kendaraan, terutama akibat kondisi jalan yang buruk. Gejala seperti kemudi yang tidak otomatis, tarikan ke satu sisi, getaran pada setir dan roda tidak seimbang dapat diatasi melalui prosedur yang terstruktur sesuai dengan standar pabrik. Mekanik merekomendasikan perawatan ini dilakukan secara rutin setiap enam bulan atau setelah 10.000 KM.

Abstract

Vocational learning in vocational high schools (SMK) needs to develop 21st-century skills, particularly critical thinking and collaboration skills. However, practical learning is still often teacher-oriented, so student active involvement is not yet optimal. Project-Based Learning (PjBL) is a learning approach that emphasizes student involvement through the completion of real projects. This study aims to analyze the effect of PjBL on students' critical thinking and collaboration skills in lathe machining practical learning at SMK Negeri 1 Cilegon. This study uses a quantitative approach with an ex post facto design. The research sample consisted of 72 students from the Machining Engineering program, selected through purposive sampling. Data were collected using a closed questionnaire that had been tested for validity and reliability. Data analysis was performed using simple linear regression with the help of IBM SPSS. The results showed that Project-Based Learning had a positive and significant effect on critical thinking skills with a contribution of 16% and on collaboration skills with a contribution of 27.9%. These findings confirm that PjBL is effective in improving critical thinking and collaboration skills among vocational high school students, especially in practical learning. This study provides empirical contributions to the development of vocational learning oriented towards work readiness and 21st-century skills.

Abstract

This study aimed to evaluate the effectiveness of the Practical Work Program (Praktik Kerja Lapangan/PKL) implementation in the Industrial Mechanical Engineering Skills Concentration at SMKN 8 Kota Serang. The evaluation was conducted because PKL is a strategic component of vocational education, yet its effectiveness needs to be continuously assessed to ensure alignment with industry demands and competency achievement. This research employed a quantitative descriptive approach using the CIPP evaluation model (Context, Input, Process, Product). The participants consisted of 31 twelfth-grade students who completed PKL. Data were collected using a Likert-scale questionnaire that had passed validity testing (25 valid items) and reliability testing with Cronbach’s Alpha of 0.909. Data analysis was performed descriptively by calculating mean scores and categorizing the results based on predetermined criteria. The findings indicate that the overall implementation of the PKL program was categorized as Very Good. In the Context aspect, the program objectives were considered relevant to industry needs. The Input aspect showed adequate readiness of students and supporting resources. The Process aspect reflected that PKL implementation and monitoring were generally conducted according to procedures. The Product aspect demonstrated positive contributions to students’ hard skills, soft skills, and work readiness. These results suggest that the PKL program has been effectively implemented and can be maintained with continuous improvement in monitoring to ensure more consistent competency development among students.

Abstract

This research aimed to develop and implement an effective character development model for Vocational High School (SMK) students in Banten Province, Indonesia. Recognizing the importance of character alongside technical skills in producing well-rounded graduates, a mixed-methods approach was employed to gather comprehensive data. Qualitative data was obtained through interviews, observations, and document analysis, while quantitative data was collected through student questionnaires. The findings revealed that SMK students value discipline, responsibility, honesty, cooperation, and mutual cooperation. However, current character development programs in schools are often fragmented and not fully integrated into daily learning. To address this, a three-component character development model was designed: 1) integrating character values into the curriculum, 2) strengthening extracurricular programs, and 3) providing personalized student support. Implementation of the model demonstrated positive outcomes, including improved student knowledge, attitudes, and behaviors related to the targeted character values. Additionally, students reported increased motivation, better social relationships, and enhanced workforce readiness. This study underscores the importance of prioritizing character development in SMK education. Schools should integrate character values into all aspects of school life, equip teachers with the necessary competencies, and foster collaboration among schools, families, and the community to create a conducive environment for student character growth.

Abstract

This study aims to analyze the factors influencing learning outcomes in the CAD subject using AutoCAD software among twelfth-grade students of the Mechanical Drawing Engineering Department at SMKN 2 Serang City. The research employs a descriptive quantitative method with a saturated sampling technique, involving 37 students as both the population and the sample. Data were collected through a Likert-scale questionnaire that had been tested for validity and reliability and were analyzed using descriptive statistics. The results indicate that students’ internal factors are in the moderate category, reflected in suboptimal motivation, interest, attention, and learning readiness, while external factors also fall within the moderate to high category, with remaining constraints in learning facilities and teaching methods that do not fully support effective AutoCAD practice. Furthermore, students’ learning outcomes in cognitive, psychomotor, and affective domains are categorized as moderate. These findings suggest that although students possess a basic understanding, their ability to independently apply AutoCAD still requires improvement through the enhancement of both internal and external learning.
