Many shipping companies were trying to deliver their cargoes as quickly and reliably as possible. But in the beginning of the latest economic crisis on 2007, the containership fleet is slowing down. Even though world oil prices are now declining, but based on the prediction of World Bank, the price of oil will rise again in 2017. Nowadays shipping company implements slow steaming method on the operation of their ships. But they do not know whether these methods are effective or not due to any negative effects arising from an implement of slow steaming like increased sailing time so may result in losses to the shippers. In this thesis will discuss the decision-making process between full speed, slow steaming, extra slow steaming and super slow steaming. This study aims to give suggestions on which ship speed is most optimal for shipping companies by considering technical and operational, financial and also environmental factors. Then, will be selected one the most optimal by using Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) method. While for criteria and sub criteria weighting are calculated by Analytic Hierarchy Process (AHP) method using Expert Choice software. From the TOPSIS method, super slow steaming is chosen to be the first rank with a value of 0,8625 while the second rank is extra slow steaming with a value of 0,5455; then slow steaming with a value of 0,3587; and finally followed by full speed with a value of 0,1283.  Banyak perusahaan pelayaran mencoba mengirimkan kargo mereka secepat dan seaman mungkin. Namun pada awal krisis ekonomi di tahun 2007, armada kapal kontainer melambat. Meski harga minyak dunia kini turun, namun berdasarkan prediksi Bank Dunia, harga minyak dunia akan naik kembali di tahun 2017.  Saat ini perusahaan pelayaran menerapkan metode slow steaming pada pengoperasian kapal mereka. Tapi mereka tidak tahu apakah metode ini efektif atau tidak karena efek negatif yang timbul dari penerapan slow steaming seperti waktu pelayaran yang meningkat sehingga dapat menyebabkan kerugian pada pengirim barang. Dalam skripsi ini akan dibahas proses pengambilan keputusan antara kecepatan penuh, slow steaming, extra slow steaming dan super slow steaming. Penelitian ini bertujuan untuk memberikan saran mengenai kecepatan kapal yang paling optimal untuk perusahaan pelayaran dengan mempertimbangkan faktor teknis dan operasional, keuangan dan juga lingkungan. Kemudian, akan dipilih yang paling optimal dengan menggunakan metode Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS). Sedangkan untuk pembobotan kriteria dan sub kriteria menggunakan metode Analytic Hierarchy Process (AHP) yang dihitung dengan menggunakan program komputer Expert Choice. Dari metode TOPSIS, super slow steaming terpilih menjadi peringkat pertama dengan nilai 0,8625 sedangkan peringkat kedua adalah extra slow steaming dengan nilai 0,5455; Kemudian slow steaming dengan nilai 0,3587; dan peringkat terakhir adalah kecepatan penuh dengan nilai 0,1283.
