SIMULASI TARIF KAPAL PENUMPANG PALING MINIMAL DENGAN OPTIMALISASI RUTE DENGAN METODE NORTH WEST COST CORNER METHOD (NWCM) DAN STEPPING STONE METHOD (SSM)
The amount of demand for sea transportation is increasing along with the development of the distribution of goods and services. It triggers various problems related to distribution, such as the problem in determining routes, sub-optimal distances, expensive travel costs, long travel times, the number of operated vehicles and other related resources. One of the efforts to solve the transportation problem is using the North West Corner Method (NWCM). NWCM is a distribution transportation method in overcoming the distribution optimization problem which is then optimized with the Stepping Stone Method (SSM) as the final method so that ship rates tend to be more optimal. This study aims to obtain the results of an effective route simulation with a more efficient passenger fare on ships. The data analysis technique in determining passenger fares is carried out at least by 2 processes, namely manual calculation and simulation using POM-QM V.3 Software. The initial data required are routes, number of ships, port capacity and initial passenger rates. The route consists of 4 intial ports and 10 final ports. The initial ports include Tanjung Priok Port, Tanjung Perak Port, Ambon Port and Bau-Bau Port. While the final ports are Tanjung Priok Port, Tanjung Perak Port, Makassar Port, Bau-Bau Port, Ambon Port, Banda Naira Port, Tual Port, Dobo Port, Kaimana Port and Fak-Fak Port. The data were processed using a 4x10 matrix table with an initial ship fare of Rp. 16,348.000 (PT. PELNI, 2019). Manual calculation using NWCM results in the amount of Rp. 23,303,300 and SSM of Rp. 25,585,900, while using the POM-QM V.3.0 software the results were Rp. 11,928,000 which is 27.03% cost savings for the 1 month period of travel.
