Abstract

Jaringan distribusi perusahaan biasanya terdiri atas multi eselon yang seringkali memiliki lebih dari satu pabrik, gudang dan juga demand point. Mengingat jaringan distribusi terdiri atas multi eselon, maka perusahaan dituntut untuk melakukan optimasi alokasi pada jaringan distribusi untuk menghasilkan biaya yang minimal dapat menggunakan model Integer Linear Programming (ILP). Model ILP harus mempertimbangkan batasan operasional dan keuangan yang ada. Model ILP yang dikembangkan juga mempertimbangkan adanya inventory dan juga multi periode. Studi kasus penelitian ini yaitu jaringan distribusi pupuk Petrogranik di PT Petrokimia Gresik. Pada penelitian ini terdapat 3 skenario perbaikan yang diusulkan untuk data tahun 2016. Berdasarkan hasil komputasi, akan dilakukan perbandingan biaya transportasi eksisting dengan biaya transportasi dari tiap skenario. Hasil komputasi menunjukkan bahwa dari tiap skenario yaitu masing-masing terjadi penghematan biaya transportasi sebesar 40%, 25% dan 34% dibanding eksisting. Alokasi berdasarkan komputasi menunjukkan bahwa jarak terjauh dari pengiriman yaitu 167 Km, sementara dari pengiriman eksisting rute terjauh yaitu 266 Km. Selain itu juga akan dilakukan perbandingan utilisasi masingmasing pabrik dari tiap skenario yang diusulkan. Komputasi juga dilakukan hingga 2020, dengan proyeksi kenaikan demand 10% tiap tahunnya ======================================================================================================= Enterprise distribution network usually consist of the multi echelon which have more than one plant, warehouse and also demand point. Considering this, so company is required to perform optimization the allocation of the distribution network to produce minimal cost. It can use the Integer Linear Programming (ILP) model. ILP model should consider the existing operational and financial constraints. ILP model developed also consider the inventory in warehouse and also multiple period. Case study in this research is concerning in the distribution network of Petroganik fertilizer in PT Petrokimia Gresik. Currently, There are 136 factories, 113 warehouses and 78 demand points. This research will provide 3 improvement scenarios proposed for data in 2016. Based on the results of the computing, will be conducted the comparison of transportation cost among the existing and from each scenario. The saving for each scenario that are scenario 0, scenario 1 and scenario 2 are 40%, 25% and 34% compared to the existing transportation cost. The allocation based on computing shows that the farthest distance of delivery is 167 Km, while the existing is 266 Km. This research also compare the factories utilization for each scenario. Computing is also performed up to 2020, with a projected increase in demand of 10% each year.
