Abstract

This study aims to evaluate the effectiveness of implementing scaffolding learning strategies in enhancing students' understanding of using the Penyipat Datar (Leveling Instrument) in the subject of Land Surveying. The subjects consisted of 32 tenth-grade students from the Building Information Modeling and Design Vocational Program (DPIB) at SMKN 11 Malang City during the 2024/2025 academic year. The research method employed Classroom Action Research (CAR) using the Kemmis and McTaggart model, conducted over two cycles, each comprising planning, action implementation, observation, and reflection stages. Data collection techniques included observation of student learning activities, formative tests to measure understanding, documentation of learning outcomes, and interviews to gather in-depth insights. The findings revealed that scaffolding strategies—applied through gradual assistance, group discussions, direct demonstrations, and peer mentoring—significantly improved students' conceptual understanding and practical skills. In Cycle I, the average student score was 69, with a learning mastery rate of 40%. After refining the strategy in Cycle II, the average score rose to 82, and the percentage of students achieving mastery increased to 84%. Statistical analysis using a paired sample t-test indicated a significant difference between the results of Cycle I and Cycle II. These findings suggest that scaffolding strategies not only effectively enhance learning outcomes but also foster independence, active participation, and procedural mastery of the instrument. Therefore, this strategy is highly recommended for sustained implementation in vocational school practice-based learning environments.

Abstract

This study aims to enhance student learning activities in the subject of Building Utility Construction Drawing and Plumbing Systems for Class XI DPIB 1 at SMK Negeri 1 Singosari through the implementation of the Problem-Based Learning (PBL) method. This Classroom Action Research (CAR) was conducted in two cycles, involving 33 students. Initial observations revealed low student participation (only 3 active students) and a learning completeness rate of 60.61%. In Cycle I, the average student activity score reached 11.94 (59.70%, MODERATE category), indicating that the success indicator (80% of students achieving the Minimum Mastery Criteria/KKM) had not yet been met. Reflections from Cycle I led to strategic improvements, such as random group formation, material visualization, reward systems, and enhancing the teacher’s role as a facilitator. In Cycle II, the student activity score increased to 16.00 (80.00%, GOOD category), with learning completeness reaching 90.91%. The findings demonstrate that PBL effectively creates an interactive, collaborative, and industry-relevant learning environment while boosting motivation, analytical skills, and students’ readiness for the workforce. This study recommends applying PBL to other technical subjects using a similar approach.
