Waktu proses pembelajaran manajemen proyek tidak seimbang dengan capaian pembelajaran sehingga diperlukan modul pembelajaran project based learning yang dapat membantu mahasiswa belajar secara mandiri. Tujuan penelitian ini menghasilkan modul pembelajaran project based learning yang valid. Metode yang digunakan penelitian dan pengembangan (Research and Development/R&D) dengan model pengembangan 4-D (empat-D) ini, yaitu: define (define phase), design (fase desain), develop (fase pengembangan), dessiminate (fase dessiminate). Data diolah menggunakan rumus Aiken V. Instrumen pengumpul data berbentuk angket yang telah divalidasi.Hasil yang diperoleh dari penelitian pengembangan ini sebagai berikut: (1) Validitas modul pembelajaran project based learning dinyatakan valid pada aspek content (isi) dengan nilai total 0,79, Validitas modul pembelajaran project based learning aspek format diperoleh nilai total 0,86 dan Validitas modul pembelajaran project based learning aspek penyajian didapat nilai 0,88. Sehingga dapat disimpulkan bahwa modul pembelajaran project based learning valid digunakan sebagai sumber pembelajaran. Kata Kunci: Manajemen Proyek, Sumber belajar, Validitas ABSTRACTThe time of the project management learning process is not balanced with the achievement of learning so it requires a project based learning learning module that can help students learn independently. The purpose of this study is to produce a valid project based learning learning module. The method used is Research and Development (R & D) with this 4-D (four-D) development model, namely: define (define phase), design (design phase), develop (development phase), dessiminate (dessiminate phase ) The data is processed using the Aiken V formula. The instruments of data collection are questionnaires that have been validated. The results obtained from this development research are as follows: (1) The validity of the project based learning learning module is declared valid in the content aspect with a total value of 0, 79, The validity of the project based learning aspects of the for-mat learning module obtained a total value of 0.86 and the validity of the project based learning learning module was 0.88. So it can be concluded that a valid project based learning learning module is used as a source of learning.Keywords: Project Management, Learning Resources, Validity
