Abstract

Abstract— Industrial development in Indonesia is increasing along with the advancement of science and technology. PT. XYZ is one of the companies that plays an important role in the aircraft industry. PT. XYZ have several departments to make their products. One of the department is the department to make component parts. In that department there are several machine that called Department machining. PT. Indonesia Aerospace (IAe) at this time, in releasing part that will be produce at Department machining using MRP (Material Requirement Planning) I method. Production planning in MRP (Material Requirement Planning) I does not calculate for capacity on the production floor and WIP (work in process). Because it does not consider that, there is often a mismatch between the plan and the actual so that it causes delays in completing the part with the specified time. Department machining in PT. XYZ can only complete parts on time by as much as 53% and 47% experience delays in completion in January 2019. To overcome this, a good production scheduling planning method is needed considering the conditions on the production floor and controlling production activities is needed called shop floor control (SPC). Load Oriented Manufacturing Control (LOMC) is a method of planning a production scheduling that takes into account the condition of the production floor. From using Load Oriented Manufacturing Control (LOMC) the release date, start date and finish date can be more accurate and can reduce discrepancy of 29,5%. Control systems using Load Oriented Manufacturing Control (LOMC) can use applications to make it easier to determine when parts will be produced so there is no bottleneck and can increase throughput. In this application there is a menu for adding parts to be produced, calculating capacity, and for knowing when the part is started and finished.

Abstrakt— Perkembangan industri di Indonesia semakin meningkat seiring dengan kemajuan ilmu pengetahuan dan teknologi. PT. XYZ adalah salah satu perusahaan yang memainkan peran penting dalam industri pesawat terbang. PT. XYZ memiliki beberapa departemen untuk membuat produk mereka. Salah satu departemen adalah departemen untuk membuat bagian-bagian komponen. Di departemen itu ada beberapa mesin yang disebut Department machining. PT. Indonesia Aerospace (IAe) saat ini, dalam merilis part yang akan diproduksi di Department machining menggunakan metode MRP (Material Requirement Planning) I. Perencanaan produksi di MRP (Material Requirement Planning) I tidak memperhitungkan kapasitas di lantai produksi dan WIP (Work In Process). Hal tersebut mengakibatkan sering ada ketidaksesuaian antara plan dan aktual sehingga menyebabkan keterlambatan dalam menyelesaikan bagian dengan waktu yang ditentukan. Department machining di PT. XYZ hanya dapat menyelesaikan order tepat waktu sebanyak 53%, dan 47% mengalami keterlambatan penyelesaian pada Januari 2019. Untuk mengatasinya, metode perencanaan penjadwalan produksi yang baik diperlukan dengan mempertimbangkan kondisi di lantai produksi dan pengendalian shop floor control (SPC). Load Oriented Manufacturing Control (LOMC) adalah metode perencanaan penjadwalan produksi yang memperhitungkan kondisi lantai produksi. Dengan menggunakan Load Oriented Manufacturing Control (LOMC) tanggal rilis, tanggal mulai dan tanggal selesai bisa lebih akurat dan dapat mengurangi ketidaksesuaian antara plan dan actual sebesar 29,5%. Kontrol sistem menggunakan Load Oriented Manufacturing Control (LOMC) dapat menggunakan aplikasi untuk mempermudah dalam menentukan kapan bagian yang akan diproduksi sehingga tidak ada bottleneck dan dapat meningkatkan throughput. Dalam aplikasi ini ada menu untuk menambahkan bagian yang akan diproduksi, menghitung kapasitas, dan untuk mengetahui kapan part itu dimulai dikerjakan dan selesai dikerjakan.
