Abstract
PT Dirgantara Indonesia merupakan industri pesawat terbang yang telah mengimplementasikan konsep lean manufacturing sejak tahun 2013. Namun, masih terdapat permasalahan pada proses produksinya, diantaranya adalah tidak tercapainya target SQCDP (Safety, Quality, Cost, Delivery & People) dan lead time produksi yang tinggi. Permasalahan tersebut menunjukkan bahwa implementasi lean manucaturing belum sesuai dengan rencana, sehingga perlu untuk dilakukan penilaian (lean assessment) dan perbaikan terhadap implementasi lean manufacturing tersebut. Dalam Tugas Akhir ini, lean assessment dilakukan dengan cara kuantitatif dan kualitatif. Dimensi yang diukur adalah efektivitas waktu, kualitas, proses, biaya, sumber daya manusia, pengiriman, pelanggan dan inventory. Setelah dilakukan pengukuran nilai leanness setiap dimensi digambarkan value stream mapping dan activity classification serta ditentukan dimensi dan waste kritis dengan borda count method. Kemudian dilakukan analisa penyebab waste kritis, analisa dampak permasalahan, penyusunan rekomendasi perbaikan, dan perhitungan nilai NPV untuk alternatif perbaikan terpilih. Berdasarkan hasil lean assessment, diketahui 3 dimensi kritis yaitu sumber daya manusia, pengiriman, dan efektivitas waktu. Value stream mapping yang diperoleh menunjukkan value added time sebesar 2.512 menit dari production lead time sebesar 18.844 menit. Output dari metode borda menunjukkan bahwa waiting, motion, dan transportation merupakan waste kritis. Untuk meminimasi pemborosan tersebut, perlu dilakukan penentuan jumlah mesin, operator, dan material handling yang optimal serta perhitungan jumlah sampling pada proses inspeksi.
Kata Kunci: Borda Count Method, Lean Assessment. ========== PT Dirgantara Indonesia is an aircraft industry that has been implementing lean manufacturing concept since 2013. However, there are still problems in its production process, such as not achieving SQCDP target (Safety, Quality, Cost, Delivery & People) and high production lead time. These problems indicate that lean manufacturing implementation is not in accordance with the plan, so it is necessary for the assessment (lean assessment) and improvements to implementation of lean manufacturing. In this Final Project, lean assessment is done in quantitative and qualitative ways. Dimensions measured are the effectiveness of time, quality, process, cost, human resources, delivery, customer and inventory. After measurement of leanness value each dimension is described value stream mapping and activity classification and determined dimension and critical waste with borda count method. Then the critical waste waste analysis, problem impact analysis, the preparation of improvement recommendations, and the calculation of the NPV value for selected improvement alternatives. Based on the results of lean assessment, known 3 critical dimensions of human resources, delivery, and time effectiveness. Value stream mapping obtained shows the value added time of 2.512 minutes of production lead time of 18,844 minutes. The output of the borda method indicates that waiting, motion, and transportation are critical waste. To minimize the waste, it is necessary to determine the optimal number of machines, operators, and material handling as well as the calculation of the number of samples in the inspection process.
