Abstract
ABSTRAK PT Cahaya Globalindo Prima adalah perusahaan industri yang memasok atau penyedia berbagai macam lampu salah satunya lampu PJU-TS. Masalah overstock terakumulasi terlalu banyak dari 2019 hingga Maret 2020 untuk bahan penolong seperti tiang octagonal, box panel baterai, braket modul, tiang lengkung, penghalang panjat dan klem diketahui memiliki tingkat overstock dengan persentase keseluruhan sebesar 36,52%. Untuk itu, manajemen pengendalian persediaan bahan baku diperlukan untuk mencapai tingkat persediaan yang optimal. Tujuan penelitian ini untuk mengetahui kapan dan berapa banyak pembelian yang harus dilakukan oleh perusahaan terhadap bahan baku penolong lampu PJU-TS dan mengetahui perbandingan perhitungan biaya persediaan dari exsisting system perusahaan dengan system P dan system Q. Dalam menentukan nilai ukuran lot pemesanan q0 dan titik pemesanan kembali r* dapat dicari dengan cara iteratif diantaranya dengan Metode Hadley-Within dan parameter sistem P, maka perhitungan manajemen persediaan setiap bahan baku dilakukan, Selanjutnya Tahap terakhir membandingkan metode usulan dengan exsisting system perusahaan. Dari sistem P dan Q didapat biaya terkecil yaitu model P untuk tiang octagonal didapat reorder point 100,0598 unit jumlah pemesanan 116,4285 unit pengehamatan biaya sebesar 0,05%. Boxt panel battery dan bracket modul didapat reorder point 109,0761 unit jumlah pemesanan 116,4285 unit pengehamatan biaya sebesar 0,26% dan 0,94% untuk bracket modul.Tiang lengkung didapat reorder point 195,8518 unit jumlah pemesanan 233 unit pengehamatan biaya sebesar 0,43%. Anti Climbing didapat reorder point 121,045 unit jumlah pemesanan 130,7142 unit pengehamatan biaya sebesar 5,48% dan komponen klem didapat reorder point 357,9902 unit jumlah pemesanan 459,7142 unit pengehamatan biaya sebesar 13,35%. Saran yang dapat diberikan mengenai model pengendalian persediaan yang optimal dalam merencanakan pemesanan bahan baku dengan melihat total biaya persediaan yang diusulkan. Kata kunci : Pengendalian persediaan, continuous review system, Periodic Review system, System P, System Q ABSTRACT PT Cahaya Globalindo Prima is industrial company that supplies or provides various lamps, one of them is PJU-TS lamps. Overstock problem is accumulated too many products since 2019 until march 2020 for supporting material such as, octagonal pole, panel box, bracket module, curved pole, climbing barrier and clamp. It is found overall overstock is as much as 36,52%. Thus, raw material stock control management is needed to reach optimum stock level. The purpose of this research is to find when and how much purchase should be done by company on supporting material PJU-TS lamps and to find stock cost calculation comparison from existing system using system P and system Q. By determining lot size in order q0 and re-order point r*, it can be found using iterative way, such as Hadley-Within method and system P parameter, thus, stock management calculation on every material is conducted. Later, the last stage is by comparing proposed method using company existing system. From P and Q system, it is derived smallest cost, which is P model for octagonal pole, it is obtained reorder point 100,0598 units, and 116,4285 units order amount, it saves as much as 0,05%. Panel box battery and bracket module reorder point is 109,0761 units and order amount is 116,4285 units, it saves as much as 0,26%; and 0,94% for bracket module curved pole, reorder point is 195,8518 units order amount is 233 units, it saves as much as 0,43%. Anti-Climbing reorder point is 121,045 units and order amount is 130,7142 units, it saves as much as 5,48%; and clamp component reorder point is 357,9902 units and order amount is 459,7142 units, it saves as much as 13,35%. Suggestion given regarding optimum stock control model in planning raw material order is by considering stock total cost proposed.
