Abstract

P ermasalahan yang terjadi pada PT. Technip FMC yaitu terdapat pemborosan berupa aktivitas yang tidak memberikan nilai tambah dalam proses transformasi input menjadi output pada value stream. Pemborosan yang terjadi berupa excess motion yang disebabkan oleh gerakan tidak perlu yang dilakukan operator pada saat proses produksi, over processing yang disebabkan oleh kegiatan inspeksi yang dilakukan secara berlebihan pada proses produksi dan defect berupa kecacatan yang terjadi pada hasil proses produksi casing head. Kecacatan yang terjadi pada produksi casing head adalah sebesar 28%. Hal ini tidak sesuai dengan target perusahaan yaitu menghasilkan produk zero defect. Tujuan dari penelitian ini adalah untuk memberikan usulan perbaikan terhadap pemborosan yang terjadi dengan penerapan metode lean manufacturing, Six sigma dan metode DMAIC. Penelitian ini diawali dengan pembuatan current value stream mapping, identifikasi waste menggunakan process activity mapping. Kemudian dilakukan perhitungan manufacturing lead time dan process cycle efficiency dan didapatkan hasil manufacturing lead time pada produksi casing head adalah sebesar 288,65 menit dengan process cycle efficiency sebesar 73%. Six sigma dan metode DMAIC digunakan untuk waste of defect dengan tahapan define, measure, analyze, improve dan control. Ishikawa diagram digunakan untuk menganalisa penyebab terjadinya pemborosan. Data yang diperoleh kemudian dilakukan pengolahan data dan hasil pengolahan data tersebut dijadikan dasar untuk merancang usulan perbaikan. Berdasarkan hasil identifikasi menggunakan diagram Ishikawa diketahui bahwa waste of excess motion disebabkan oleh faktor method dan material, waste of over processing disebabkan oleh faktor man dan method serta waste of defect. Usulan perbaikan yang diberikan berupa rak penyimpanan , material handling conveyor, penggabungan kegiatan inspeksi, machine maintenance checklist, form jadwal kalibrasi, term of reference pelatihan operator, SOP pekerja dan penerapan metode 5R. Berdasarkan hasil implementasi dari usulan perbaikan tersebut didapatkan penurunan manufacturing lead time menjadi 285,37 menit serta peningkatan process cycle efficiency menjadi 74%.

T he problems that occurred at PT. Technip FMC there is waste in the form of activities that do not provide added value in the transformation process input becomes output on the value stream. The waste that occurs is: excess motion caused by unnecessary movements made by the operator during the production process, over-processing caused by inspection activities carried out excessively in the production process, and defects in the form of defects that occur in the results of the production process casing head. Defects that occur in the production casing head is 28%. This is not following the company's target of producing products with zero defects. The purpose of this study is to provide suggestions for improvements to the waste that occurs by applying the lean manufacturing method, six sigma, and the DMAIC method. This research begins with making current value stream mapping, and identification waste use process activity mapping. Then do the calculations for manufacturing lead time and process cycle efficiency and got the results manufacturing lead time on the production casing head is equal to 288.65 minutes with process cycle efficiency by 73%. Six sigma and the DMAIC method are used for waste of defect with stages define, measure, analyze, improve, and control. Ishikawa diagram is used to analyze the causes of waste. The data obtained is then processed and the data processing results are used as a basis for designing improvement proposals. Based on the identification results using the Ishikawa diagram, it is known that waste of excess motion due to method and material factors, waste of over-processing due to man and method factors as well as waste of defect. The proposed improvements include storage racks, material handling conveyor, consolidation of inspection activities, machine maintenance checklist, calibration schedule form, term of reference operator training, worker SOP and application of the 5S method. Based on the results of the implementation of the proposed improvements, it was found that there was a decrease in manufacturing lead time to 285.37 minutes and an increase in process cycle efficiency to 74%.
