PENGOPTIMALAN POLA DISTRIBUSI BBM MENGGUNAKAN TEORI TRANSPORTASI DAN METODE STEPPING STONE PADA PT. PERTAMINA PATRA NIAGA REGIONAL SUMATERA BAGIAN SELATAN

Abstract

Abstrak

PT Pertamina Patra Niaga Regional Sumbagsel merupakan Sub Holding Commercial & Trading PT
Pertamina (Persero) yang bertugas menjalankan proses bisnis berupa perdagangan, penanganan bahan
bakar, manajemen armada dan depot, serta menjalankan rantai kegiatan bisnis hilir pertamina dengan
wilayah kerja pulau Sumatera bagian selatan. Untuk mendistribusikan BBM PT Pertamina Patra Niaga
Regional Sumbagsel menggunakan kereta api dan kapal laut, namun kedua moda transportasi ini seringkali
mengalami hambatan. Penelitian ini bertujuan untuk menentukan pola distribusi yang efisien jika PT
Pertamina Patra Niaga akan melakukan distribusi BBM menggunakan moda transportasi truk tangki.
Berdasarkan permasalahan teori transportasi tersebut maka dilakukan perhitungan menggunakan metode
North West Corner (NWC), Least Cost, dan Vogel’s Aproximation Method (VAM) lalu diuji optimalisasi
menggunakan metode Stepping Stone untuk mendapatkan pola distribusi dengan biaya terendah.
Berdasarkan hasil pengolahan data didapatkan pola distribusi yang dihasilkan metode Vogel’s
Aproximation Method (VAM) adalah solusi paling efisien dan sudah teruji optimal dengan metode uji
optimalisasi Stepping Stone. Total biaya distribusi yang harus dikeluarkan jika menggunakan metode ini
adalah Rp 8.488.145.521.

Abstract

[OPTIMIZING THE FUEL DISTRIBUTION PATTERN USING TRANSPORTATION THEORY AND
STEPPING STONE METHOD AT PT. PERTAMINA PATRA NIAGA REGIONAL SOUTH
SUMATRA] PT Pertamina Patra Niaga Regional Southern Sumatra is PT Pertamina's Sub Holding
Commercial & Trading which is tasked with carrying out business processes in the form of trading, fuel
handling, fleet and depot management, as well as running Pertamina's downstream business activity chain
with the working area of the southern part of Sumatra Island. To distribute fuel, PT Pertamina Patra Niaga
Regional Sumbagsel uses trains and ships, but these two modes of transportation often experience obstacles.
This study aims to determine an efficient distribution pattern if PT Pertamina Patra Niaga will distribute
fuel using a tanker truck mode of transportation. Based on these transportation theory problems,
calculations are carried out using the North West Corner (NWC), Least Cost, and Vogel's Approximation
Method (VAM) methods and then tested for optimization using the Stepping Stone method to obtain the
distribution pattern with the lowest cost. Based on the results of data processing, it was found that the
distribution pattern produced by Vogel's Approximation Method (VAM) is the most efficient solution and
has been optimally tested using the Stepping Stone optimization test method. The total distribution costs that
must be incurred if using this method is IDR 8,488,145,521.
