| Summary: | The two main factors associated with the performance of the distribution
system is the service factor and factor costs, where the farther the distance
covered in the delivery of goods will lead to long delivery time and result in
higher operating costs. This study was conducted to analyze the optimal
distribution of sugar in the PG. Madukismo using network analysis tools based
Geographic Information System. In addition, this study also perform comparative
analysis between network analysis and Tabu Search through the simulation of a
distribution system improvement recommendations in PG. Madukismo in the
selection of the optimal route distribution.
Descriptive and quantitative analysis of the results in this research showed
that the determination of the route using network analysis tools based on
Geographic Information System is more optimal than if the company uses the
previous route. The proposed use of network analysis produces a more optimal
route in terms of distance, time, and cost. The total distribution costs incurred by
the proposed route analysis performed was Rp 964,063.83, with a travel time of
5.82 hours for 145.98 km mileage. Meanwhile, if the determination was based on
the existing routes, the total distribution costs incurred by the analysis conducted
was Rp 979,591.93, with a travel time of 6.74 hours for 174.83 km mileage. For
the analysis of simulation results show that the Tabu Search is able to produce a
shorter distance is 62.05 miles than network analysis that generates a distance of
73.14 km. However, tabu search methods can not be implemented due to the
company's distribution system of the company is non-canvassing while the tabu
search is more suitable when used in companies that have a distribution system
canvassing. Therefore, the determination of the optimal route with tabu search can
be recommended for the improvement of the distribution system for the company
in future studies. So network-based Geographic Information System analysis is
more suitable in this study.
