Abstract
Production scheduling is the most important part in carrying out the production process that will be carried out on a production floor. Scheduling activities are carried out before the production process begins to ensure the smooth running of the production process. If the production scheduling is not done properly, there will be obstacles in the production process and will cause losses to the company. This study aims to determine the production machine scheduling in a company engaged in the manufacture of spare parts for automotive products. This company implements a job shop production process and uses the First In First Out method in completing its work. Due to the large number of products that have to be produced, there are often two or more products that must be worked on at the same time and machine. This condition causes some products to have to wait for the associated machine to finish operating and causes long product turnaround times. This problem is solved by making a production machine scheduling using the Non-Delay method. By applying this method, the makespan of completion time can be minimized.

Summary
Berbagai pengertian maupun definisi mengenai penjadwalan telah dikemukakan oleh para ahli. Conway et al (1967) yang mendefinisikan penjadwalan sebagai proses pengurutan pembuatan produk secara menyeluruh pada beberapa mesin. Kemudian Baker (1974) mengemukakan penjadwalan sebagai proses pengalokasian sumber daya dalam jangka waktu tertentu untuk melakukan serangkaian tugas. Morton (1993), penjadwalan adalah proses pengorganisasian, pemilihan, dan penentuan waktu penggunaan sumbersumber untuk mengerjakan semua aktivitas yang diperlukan sehingga memenuhi kendala aktivitas dan sumber daya. Metodologi Penelitian Metode penelitian yang diangkat pada penelitian ini dapat diuraikan sebagai berikut: Identifikasi permasalahan, penetapan tujuan penelitian dan pengumpulan data. Tujuan penelitian adalah untuk menentukan penjadwalan mesin produksi dengan menerapkan Metode Penjadwalan NonDelay sehingga dapat meminimasi completion time. Data yang dibutuhkan dalam mengaplikasikan metode penjadwalan ini terdiri dari data jenis spare part permintaan konsumen, tahapan pengerjaan spare part tersebut beserta waktu proses tiap tahapannya serta mesin yang digunakan untuk berproduksi
