Abstract

PT XYZ merupakan pemasok tinta packaging dengan model business to business dengan sumber revenue dari tiga pelanggan utama. Tantangan yang dihadapi perusahaan adalah rendahnya tingkat pengiriman tepat waktu akibat penerimaan 17,62% pesanan dengan permintaan lead time yang lebih singkat dari yang bisa PT XYZ tawarkan. Salah satu upaya yang dapat dilakukan perusahaan adalah peningkatan kapasitas produksi. Untuk menyelesaikan pesanan pelanggan, perusahaan menggunakan aliran produksi job-shop yang melibatkan antrean pesanan. Pendekatan simulasi kejadian diskrit digunakan untuk menentukan jumlah sumber daya produksi untuk meningkatkan performa pengiriman tepat waktu ke target perusahaan yaitu 95%, dalam kondisi pesanan standar. Skenario rekomendasi perbaikan adalah penambahan 2 teknisi lab dan 3 mixer kecil serta pengurangan 1 pekerja produksi. Pada kondisi standar, rekomendasi perbaikan dapat menyelamatkan pemasukan bulanan perusahaan sebesar rata-rata Rp 2.022.938.750 akibat peningkatan persentase pengiriman tepat waktu dari 54,60% menjadi 95,61%. Pada kondisi peak order, rekomendasi perbaikan dapat menyelamatkan pemasukan bulanan perusahaan sebesar rata-rata Rp 3.718.196.250 akibat peningkatan persentase pengiriman tepat waktu dari 33,82% menjadi 90,90%. Skenario perbaikan membutuhkan biaya tetap sebesar Rp 1.052.000.000 dan mengakibatkan peningkatan rata-rata total biaya variabel sebesar Rp 7.701.507 pada kondisi standar dan Rp 6.670.275 ketika peak order. Rekomendasi solusi menghasilkan NPV yang lebih besar dibandingkan kondisi awal sehingga layak diimplementasikan.
=================================================================================================================================
PT XYZ is a packaging ink supplier with a business-to-business model with sources of income from three main customers. The challenge faced by the company is the low level of on time delivery because it received 17.62% of orders with a shorter lead time than that offered by PT XYZ. One effort that the company can do is to increase production capacity. To complete customer orders, companies use job-shop production flows that involve order queues. A discrete event simulation approach is used to determine the amount of production resources to increase on-time delivery performance according to the company target of 95%, under standard order conditions. The best scenario is the addition of 2 lab workers and 3 small mixers accompanied by a reduction of 1 production worker. The recommended scenario can save the company's average monthly revenue of IDR 2,022,938,750 due to an increase in the percentage of on-time delivery from 54.60% to 95.61%. In peak order conditions, recommended improvements can save the company's revenue of IDR 3,718,196,250 on that specific month due to an increase in the percentage of on-time delivery from 33.82% to 90.90%. The recommended scenario requires fixed costs of IDR 1,052,000,000 and results in an average increase in total variable costs of IDR 7,701,507 under standard conditions and IDR 6,670,275 during peak orders. This recommendation produces an NPV value that is greater than the initial condition, making it feasible to implement.
