Abstract

PT XYZ is one of the company that move in telecommunications services, starter pack products, and vouchers. The problems in PT XYZ is lateness of starter pack activation in regional warehouse that cause waiting time of starter pack’s pick up by retailer. Lateness problem happened because there is no fixed scheduling policy yet, so there is no determination of job’s priority. In this research will be developed scheduling policies including job allocation each machine per day and sequencing of job. The method used is the earliest due date. In this method, job sequence will be determined based on the smallest due that influence the Completion time of a job. Scheduling do for one machine that doing six jobs in one week. The data used is the starter pack activation data in October 2014. Based on the existing calculations condition, there is a delay of 7.8 hours on job Site  s in Jakarta and 15.3 hours on job Site  s Surabaya. Processing time and due date of each job are the input in the methods used. The results of calculation of the proposed conditions in PT XYZ by using a method capable of lowering the earliest due date delay activation up to 38% compared to the existing condition. Completion time of 6 job in a week with the existing condition is 30.3 hours to 18.3 hours on the proposed conditions.


PT XYZ merupakan salah satu perusahaan yang bergerak di bidang jasa telekomunikasi, produk starter pack, dan voucher pulsa. Permasalahan yang terjadi pada PT XYZ yaitu keterlambatan aktivasi starter pack digudang regional yang menyebabkan terjadinya waktu tunggu pengambilan starter pack oleh retailer. Permasalahan keterlambatan terjadi karena belum adanya kebijakan penjadwalan pasti, sehingga belum adanya penentuan prioritas job. Pada penelitian ini, akan dikembangkan kebijakan penjadwalan termasuk pembagian job setiap mesin per hari dan pengurutan pengerjaan job. Metode yang digunakan adalah earliest due date. Pada metode ini akan ditentukan urutan pengerjaan job berdasarkan due date terkecil yang berpengaruh terhadap waktu penyelesaian suatu job. Penjadwalan dilakukan terhadap satu mesin yang mengerjakan enam job dalam satu minggu. Data yang digunakan adalah data aktivasi starter pack periode Oktober 2014. Berdasarkan perhitungan kondisi eksisting, terdapat keterlambatan 7.8 jam pada job site Jakarta dan 15.3 jam pada job site Surabaya. Waktu proses dan due date setiap job akan menjadi input-an dalam metode yang digunakan. Hasil dari perhitungan kondisi usulan di PT XYZ dengan menggunakan metode earliest due date mampu menurunkan keterlambatan aktivasi starter pack hingga 38% dibanding kondisi eksisting. Waktu penyelesaian 6 job dalam satu minggu pada kondisi eksisting 30.3 jam menjadi 18.3 jam pada kondisi usulan.
