Abstract
PT. XYZ merupakan perusahaan minyak goreng yang berada di Jawa
Timur dengan memproduksi 11 macam minyak goreng dengan kemasan standing
pouch. Proses pengisian minyak goreng dilakukan di mesin Thimonier yang
tersedia sebanyak 6 buah. Setiap pergantian jenis produk pada proses pengisian di
mesin Thimonier yang sama maka perlu dilakukan set up mesin dan flushing jalur.
Set up mesin membutuhkan waktu 1-2 jam. Adanya set up mesin menyebabkan
kapasitas produksi berkurang. Sementara itu, minyak goreng bekas proses
flushing jalur tidak diikutkan dalam proses pengisian sehingga dihitung sebagai
kerugian. Oleh karena itu kedua variabel tersebut harus diminimalkan dengan cara
membuat bauran produk yang tepat. Langkah pertama yaitu melakukan peramalan
permintaan menggunakan metode dekomposisi. Langkah kedua yaitu
memaksimalkan keuntungan menggunakan metode pure integer programming.
Variabel keputusan yang digunakan yaitu jumlah minyak goreng yang harus
diproduksi, flushing jalur dan set-up mesin, inventori bahan baku dan kelebihan
serta kekurangan produk. Fungsi pembatas yang digunakan yaitu pembatas
permintaan minyak goreng, kapasitas produksi, flushing dan set-up serta bahan
baku yang dibutuhkan
===========================================================================================
PT. XYZ is a manufacturer of cooking oil in East Java. The company
produces 11 types of standing pouch cooking oil. The filling process is conducted
by using six Thimonier machines. Flushing of filling lines and set-up have to be
performed every time the company changes the type of product. The set-up time is
quite long, i.e., 1-2 hours, which decreases the production capacity. Meanwhile,
the flushing cooking oil would not be included in the filling process and
considered as a loss. Therefore, both flushing of filling lines and set-up should be
minimized. To solve the problem, the company should develop the right product
mixture to obtain maximum profit. The first step is to forecast the demand by
using decomposition method. The second step is to maximize the profit by using
pure integer programming method. As the decision variables are the number of
cooking oil that must be produced, flushing of filling lines and set-up, raw
material inventory, excessive number and stock out of cooking oil produced. The
constraints are cooking oil demand, capacity, flushing and set-up, and raw
material required.
