ABSTRAK

PT. Varia Usaha sebagai salah satu perusahaan yang bergerak perdagangan barang industri secara job order dituntut untuk senantiasa melakukan perbaikan agar kegiatan usaha semakin efisien. Salah satu bentuk perbaikan secara terus- menerus adalah dengan menerapkan lean manufacturing. Penelitian untuk mengestimasikan usaha perbaikan dilakukan pada produk Cement Bulk Tank dengan tujuan untuk mengurangi aktivitas yang tidak mempunyai nilai tambah atau waste sehinggga lead time produksi dan biaya bisa dikurangi. Identifikasi awal untuk mengetahui aktivitas yang tidak bernilai tambah dilakukan dengan Big Picture Mapping untuk menggambarkan keseluruhan proses produksi. Selanjutnya dilakukan pemetaan berdasarkan jenis pemborosan yang dominan menggunakan metode Value Stream Mapping Tools VALSAT. Dari proses pengolahan data diperoleh mapping yang terpilih yaitu Process Activity Mapping dan Supply Chain Response Matrix. Hasil pengolahan Process Activity Mapping diketahui bahwa aktivitas yang tidak bernilai tambah sebesar 84.815 menit. Usaha perbaikan dilakukan untuk menurunkan lead time produksi didapatkan pengurangan dari kondisi awal 86 hari menjadi 74 hari. Sedangkan pengurangan biaya untuk 1 unit tanker adalah 13.714.125- atau 212 .


ABSTRACT

Varia Usaha Ltd. the company that produce goods by job order forced to improve process to be efficient business activity progressively. The Company apply continues improvementsby applying lean manufacturing. The final research want to estimating the improvement effort for product that names Cement Bulk Tank that aimed for reducing the activity that not added value or waste as well as the lead time production and cost can be minimize. The first Identification is to know the activity that is not value added describe by Big Picture Mapping to bring general information about production process. Then continued by mapping waste type using the Value Stream Mapping Tools Method VALSAT.The Valsat Method giving three kind of mapping ttpes there are Process Activity MappingSupply Chain Response Matrix and Demand Amplification Mapping. From data processing result known that the activity which is not value added time equal to 84.815 minute. Improvement recomendation that was estimating to reduction the lead time from existing condition of 86 days become 74 day. While cost reduction to 1 unit tanker is 13.714.125 rupiah or more efficient 212 then before.
