Abstract
Divisi Produksi Pengecoran (Workshop I) di PT. Barata Indonesia memiliki permasalahan yang paling kompleks disbanding divisi-divisi lainnya. Penggunaan sumber daya produksi seringkali tidak efisien sehingga mengakibatkan rendanya produktivitas. Penelitian ini akan mengidentifikasi pemborosan (waste ) yang teijadi dalam proses produksi yang mengganggu tingkat produktivitas. Penelitian diawali dengan pengukuran produktivitas menggunakan metode Objective Matrix (OMAX) berdasarkan beberapa kriteria produktivitas parsial. Selanjutnya, pendekatan lean manufacturing dimanfaatkan untuk mengidentifikasi jenis-jenis waste yang paling banyak teijadi. Metode-metode yang digunakan antara lain: Process Activity Mapping, Supply Chain Responce Matrix dan Quality Filter Mapping. Kemudian dianalisa akar penyebab pemborosan tersebut yang kemudian diberikan rekomendasi perbaikan guna meminimasi pemborosan yang teijadi sehingga produktivitas perusahaan meningkat. Hasil pengukuran dengan menggunakan OMAX menunjukkan indeks produktivitas bulanan masing - masing kriteria mengalami penurunan di Bulan November dan Februari. Sedangkan pendekatan lean manufacturing memmjukkan waste yang paling banyak teijadi adalah defect dan waiting. Beberapa rekomendasi perbaikan, misalnya sistem paralel pattern & core making, pemberian papan patuh SOP, alat bantu penataan dalam furnace, melakukan quenching & tempering dengan rentang waktu kurang dari 8 jam, dan mempeibaiki sistem preventive maintenance guna meminimasi waste yang teijadi sehingga produktivitas perusahaan meningkat.

Foundry Division of PT. Barata Indonesia demonstrates the highest level of complexity compared to other divisions. The use of reseources is often inefficient which potentially affect the low productivity level. This study tried to identify any waste which probably occured in the production process that might bother the level of
productivity. The study began with measuring productivity by using Objective Matrix (OMAX) based on some criteria of partial productivity. Subsequently, an approach of lean manufacturing was utilized to identify type of waste which mostly occured. The methods used here are Process Activity Mapping, Supply Chain Response Matrix and Quality Filter Mapping as well. Finally, the root cause of each waste was analyzed in order to design a proper recomendation for minimizing waste and increasing productivity. The result of OMAX repreasented the monthly productivity index for each criterion declined on November and February while lean manufacturing resulted the largest amount of waste are defect and waiting. Some recommendations for instance : parallel system ofpattern & core making, giving the SOP compliance board, structuring tools in the furnace, do quenching & tempering with the time span of less than eight hours, and improve preventive maintenance system are proposed in the final chapter in order to decrease waste and improve productivity.
