Abstract

PT. XYZ adalah salah satu perusahaan yang bergerak dalam bidang elektromedis yang banyak menopang alat kesehatan dalam negeri beberapa tahun terakhir. Permintaan alat elektromedis dilihat dari data penjualan sangat fluktuatif dan susah untuk ditebak, selain itu 70% dari permintaan yang diterima berasal dari institusi pemerintah. Permasalahan ditambah dengan tidak adannya kebijakan peramalan sehingga perencanaan kegiatan produksi menjadi tidak maksimal. Persediaan produk yang tidak dibarengi dengan perhitungan yang matang akan mengakibatkan overstock dan stockout yang dapat meningkatkan total cost dan menurunkan service level. Dalam menjalankan bisnisnya PT. XYZ menerapkan kebijakan pengelolaan persediaan eksisting yang dilakukan dengan pemesanan komponen produk dalam jumlah banyak namun belum ada reorder point yang jelas. Sehingga dalam tesis ini akan dilakukan pengamatan terhadap komponen produk CMS-600 PLUS, ECG-1200G, TENSIONE, ECG-300G, SON-C, SON-B, SON�PRO, USG PROMAX, PROMIST-3, MED-01, ECG-100G, dan ULTRAMIST lalu diusulkan metode peramalan Croston dan Syntetos-Boylan Approximation (SBA) untuk meperkirakan kemungkinan demand pada waktu yang akan datang lalu kebijakan pengelolaan persediaan continuous review (s,S) dan (s,Q) untuk menentukan nilai reorder point, maksimal stok dan kuantitas order. Setelah itu, dilakukan simulasi monte carlo untuk melihat dan membandingkan kebijakan eksisting dengan kebijakan perbaikan berdasarkan variabel total cost dan service level. Selanjutnya dilakukan analisis sensivitas untuk mengetahui robust model simulasi terhadap perubahan ketidakpastian. Hasil yang didapatkan adalah rekomendasi kebijakan continuous review (s,Q) dengan penghematan total cost sebesar Rp22.206.322.981 dan peningkatan sevice level 1,36% menjadi 99,98% dari pada kebijakan eksisting.

PT. XYZ is one of the companies engaged in the electromedical field that has supported many domestic medical devices in recent years. Demand for electromedical devices seen from sales data is very fluctuating and difficult to guess, besides that 70% of the requests received come from government institutions. The problem is compounded by the absence of a forecasting policy so that the planning of production activities is not maximized. Product inventory that is not accompanied by a careful calculation will result in overstock and stockout which can increase total costs and reduce service levels. In running its business, PT. XYZ implements an existing inventory management policy which is carried out by ordering product components in large quantities but there is no clear reorder point. So in this thesis, observations will be made of product components CMS-600 PLUS, ECG-1200G, TENSIONE, ECG-300G, SON-C, SON-B, SON-PRO, USG PROMAX, PROMIST-3, MED-01, ECG-100G, and ULTRAMIST and then the Croston and Syntetos-Boylan Approximation (SBA) forecasting methods are proposed to estimate the possibility of demand in the future and the continuous review inventory management policies (s,S) and (s,Q) to determine the reorder point value, maximum stock and order quantity. After that, a monte carlo simulation is carried out to see and compare existing policies with improved policies based on total cost and service level variables. Furthermore, a sensitivity analysis is carried out to determine the robustness of the simulation model to changes in uncertainty. The result obtained is a continuous review (s,Q) policy recommendation with total cost savings of Rp22,206,322,981 and an increase in service level of 1.36% to 99.98% from the existing policy.
