Abstract

Abstrak PT XYZ perusahaan industri manufaktur yang memproduksi peralatan elektronik. Penelitian ini, berfokus pada Modul Surya 260 WP. Berdasarkan data tahun 2017, permasalahan pada perusahaan ialah ketidaktercapaian produksi sehingga mengalami keterlambatan pengiriman produk. Berdasarkan permasalahan, diperlukan penelitian mengenai permasalahan yang terjadi menggunakan lean manufacturing. Tahap pertama yaitu menggambarkan proses produksi dengan process activity mapping (PAM) dan value stream mapping (VSM). Diketahui lead time sebesar 21151,24 detik dan value added sebesar 3404,37 detik. Lead time berisikan aktivitas value added, necessary non-value added dan non-value added. Berdasarkan PAM diketahui aktivitas waste waiting dalam proses produksi. Selanjutnya, tahap kedua mengidentifikasi akar penyebab waste waiting menggunakan fishbone. Akar penyebab waste waiting akan diminimasi dengan menggunakan line balancing dan penataan station sealant. Rancangan usulan perbaikan diharapkan waktu siklus dari aktivitas waste waiting akan berkurang atau hilang. Aktivitas tersebut yaitu menunggu kedatangan modul untuk diproses, menunggu modul untuk framing dan modul menunggu untuk di sealant. Berdasarkan rancangan usulan perbaikan, didapatkan lead time sebesar 6185,39 detik dengan value added 3404,37 detik dengan menerapkan penyeimbangan lintasan pada workstation terminating, layup, EL, trimming El2, Sun Simulator, framing dan testing dan menata station sealant.

Kata kunci : Lean Manufacturing, Waste Waiting, Line Balancing, Value Stream Mapping, Process Activity Mapping Abstract PT XYZ company manufacturing industries producing of electronic equipment. The study, focusing on the Solar Module 260 WP. Based on data for the year 2017, problems in the company is achievement makes delay in product delivery. Based on problems, needed research on problems occurred using lean manufacturing. The first stage that is described the process of production with process activity mapping (PAM) and value stream mapping (VSM). Known lead time of 21151.24 seconds and value added of 3404.37 seconds. Lead time contains a value added activity, necessary non-value added and non-value added. Based on the PAM, known activity of waste waiting in the production process. Next, the second stage is to identify the root cause of waste waiting using a fishbone. The root cause of waste waiting will be minimize by using the line balancing and design of sealant station. The draft proposal of the improvement is expected from the activity cycle time waste waiting will be reduced or lost. The event that is waiting for the arrival of the module for processing, waiting for module to framming and module is waiting to sealant. Based on the design of the proposed improvements, obtained lead time of 6185.39 seconds with value added 3404.37 seconds by applying a balancing trajectory on workstation terminating, layup, trimming, El2, Sun Simulator, framing and testing and setting the station sealant.
