Abstract

Proyek konstruksi pembangunan Hotel & Resort di Samosir adanya potensi terjadinya keterlambatan pekerjaan. Oleh karena itu diperlukan satu inovasi dalam upaya peningkatan kinerja biaya melalui integrasi metode Lean Construction dan manajemen risiko berbasis  Java Programming pada proses forecasting untuk optimasi kinerja biaya proyek konstruksi bangunan precast. Lean Construction merupakan metode yang bertujuan untuk simulasi peningkatan value atau nilai tambah produksi serta mengurangi biaya operasi (waste). Sedangkan manajemen risiko merupakan tata kelola untuk menentukan rencana tindak lanjut atas beberapa kejadian yang memiliki dampak pada kelangsungan suatu proyek. Dalam hal ini integrasi atas dua metode tersebut akan dibuat dalam sebuah program pemodelan berbasis Java Programming. Hasil dari simulasi integrasi metode Lean Construction dan manajemen risiko, dimana besarnya biaya risiko sebelum dioptimasi yaitu Rp 14,753milyar. Selanjutnya dari hasil analisis optimasi dengan Lean Construction dan manajemen risiko berbasis aplikasi Java Programming,maka hasilnya adalah biaya risiko turun sebesar 51% menjadi Rp 7,230milyar.

Abstract

This study aims to develop a SketchUp E-Module as an innovative competency-based learning medium for the Planning Drawing course in the Building Engineering Education Study Program at Universitas Negeri Padang. This research is motivated by the absence of structured module-based teaching materials, as well as learning processes that are still dominated by demonstration methods, videos, and PowerPoint. The research method used is Research and Development (R&D) with the DDD-E development model, which includes the stages of Decide, Design, Develop, and Evaluate. The research subjects consisted of lecturers and students from the Building Engineering Education Study Program. The instruments used were validation questionnaires by material experts and media experts, as well as practicality questionnaires completed by students. Data analysis techniques employed Aiken’s V formula for validity and percentage analysis for practicality. The results of the study indicate that the developed E-Module has a high level of validity, with media expert validation reaching 91.5% (very feasible) and material expert validation reaching 80% (feasible). In addition, the practicality test results from students showed an average score of 96.67%, categorized as very practical. This demonstrates that the developed SketchUp E-Module is easy to use, engaging, and effective in helping students understand the material and improve their 3D building design skills. Thus, it can be concluded that the competency-based SketchUp E-Module developed in this study is both feasible and highly practical to be used as an innovative learning medium in the Planning Drawing course.

Abstract

The rapid adoption of Building Information Modeling (BIM) in the construction industry requires vocational civil engineering graduates to develop competencies beyond technical modeling skills, including interdisciplinary coordination and collaborative project workflows. However, BIM instruction in vocational higher education remains predominantly software-oriented and lacks structured integration of authentic industry practices within formal coursework. This study aimed to develop and validate a semester-integrated simulation-based learning model embedded in a compulsory BIM course. Using a Research and Development approach based on the ADDIE framework, the study involved competency gap analysis, model design, expert validation, and classroom implementation. Five experts—two BIM academics, one instructional design specialist, and two industry practitioners—evaluated the model, resulting in an overall mean feasibility score of 4.48 (SD = 0.18), categorized as Highly Valid. The model was implemented over one semester with 32 fourth-semester students. CLO-aligned performance assessment showed average scores of 82.6 in modeling accuracy, 79.4 in coordination quality, 84.1 in clash detection effectiveness, and 86.3 in teamwork, while 81% of students reported improved understanding of interdisciplinary BIM workflows. The findings demonstrate that structured simulation supports industry-aligned competency development in vocational BIM education.
