Peningkatan efisiensi rantai pasok Crude Palm Oil (CPO) pada Ptpn vii Unit Pks Talang Sawit
P PTPN VII Unit PKS Talang Sawit mengelola komoditi perkebunan kelapa sawit untuk diolah menjadi Crude Palm Oil (CPO) atau yang biasa juga disebut dengan minyak kelapa sawit dan biji kelapa sawit (kernel). Berdasarkan observasi secara langsung dan wawancara dengan beberapa pihak diperoleh permasalahan adanya keterlambatan datangnya bahan baku sampai ke pabrik. Selain itu permasalahan lainnya terjadi saat melakukan pemindahan buah kelapa sawit dari stasiun loading ramp menuju stasiun kerja boiler masih menggunakan lorri yang ditarik oleh beberapa pekerja dengan menggunakan tali tambang. Hal tersebut menyebabkan waste pada bagian transportasi pemindahan bahan baku. Penelitian ini berfokus pada produksi Crude Palm Oil (CPO) dan bertujuan untuk meningkatkan efisiensi dan mengurangi manufacturing lead time. Pendekatan Lean Supply Chain digunakan untuk mengidentifikasi dan meminimalisasi terjadinya pemborosan yang terjadi. Penelitian diawali dengan melakukan pemetaan menggunakan Current State Value Stream Mapping dengan hasil PCE sebesar 86,83% dan nilai Manufacturing Lead Time sebesar 2.620 menit atau 43,66 jam. Pemetaan Process Activity Mapping yang dilakukan mengidentifikasi kegiatan non value added sebesar 4,8%, dan pada pemborosan waiting sebesar 25,09%, transportation sebesar 44,89%, unnecessary motion sebesar 21%, defect sebesar 1%, dan underutilized people sebesar 8% untuk seluruh kegiatan rantai pasok. Perbaikan yang dilakukan seperti pembuatan SOP Kriteria Penerimaan Bahan Baku, SOP Seleksi dan Evaluasi Supplier serta Form Seleksi dan Evaluasi Supplier, Pengadaan Conveyor, Penambahan pisau pada mesin Digester, dan terakhir Training Operator, Penggantian gear box pada mesin thresher, dan perawatan rutin terhadap mesin. Usulan - usulan ini dipetakan dengan Process Activity Mapping perbaikan, sehingga dari hasil pemetaan menggunakan peta aliran pross dan perhitungan kuantitatif terjadi penurunan Manufacturing Lead Time sebesar 345 menit atau 5,75 jam sehingga menjadi 2.275 menit atau 37,91 jam, dan kegiatan non value added menjadi 2,9%. Pada pemetaan Future State Value Stream Mapping juga terjadi kenaikan PCE sebesar 4,67%, sehingga PCE menjadi 91,50%.
P PTPN VII Talang Sawit PKS Unit manages oil palm plantation commodities to be processed into Crude Palm Oil (CPO) or also known as palm oil and palm kernel (kernel). Based on direct observations and interviews with several parties, it was found that there was a problem with delays in the arrival of raw materials to the factory. In addition, other problems occurred when transferring palm fruit from the loading ramp station to the boiler work station, still using lorries which were pulled by several workers using ropes. This causes waste in the transportation section of raw material transfer. This research focuses on Crude Palm Oil (CPO) production and aims to increase efficiency and reduce manufacturing lead time. The Lean Supply Chain approach is used to identify and minimize waste that occurs. The research was started by mapping using Current State Value Stream Mapping with a PCE result of 86.83% and a Manufacturing Lead Time value of 2,620 minutes or 43.66 hours. Mapping Process Activity Mapping that was carried out identified non-value added activities of 4.8%, and waste of waiting by 25.09%, transportation by 44.89%, unnecessary motion by 21%, defects by 1%, and underutilized people by 8 % for all supply chain activities. Improvements were made such as making SOP for Raw Material Acceptance Criteria, SOP for Supplier Selection and Evaluation and Supplier Selection and Evaluation Forms, Procurement of Conveyors, Adding blades to the Digester machine, and finally Operator Training, Replacement of the gear box on the thresher machine, and routine maintenance of the machine. These proposals are mapped with Process Activity Mapping improvements, so that from the mapping results using process flow maps and quantitative calculations there is a decrease in Manufacturing Lead Time by 345 minutes or 5.75 hours to 2,275 minutes or 37.91 hours, and non-value added activities to 2.9%. In the Future State Value Stream Mapping mapping, there is also an increase in PCE of 4.67%, bringing the PCE to 91.50%.
