12 Optimization of Route Selection …

nodes (numbers) which are 1, 3, 5, 7, 11, 13, 15, and 17 are suggested as the first
nodes covered for the waste due to the peak time and road condition. This area is
located far from the nearest school and nearest residential area. It will probably effect
the process of collecting waste and the speed of the truck in order to avoid accidents
and poor road congestion due to industrial activities. Other than that, collecting the
garbage at the remaining nodes at the afternoon session will avoid the peak hours of
road usage. Nevertheless, the final location to dump the waste is located at the Segari
Landfill which is convenient to select the nearest nodes to the last nodes.
12.4.3 Result of Carbon Emission
The suggested route is the route that is defined and measured by using the TSP method
while the actual distance route is the result that is obtained from the motion study
that was conducted mutually with MPM Sitiawan. Estimated distance is the route
based on the estimated distance traveled from interview session which is 100 km
per route. Based on [12], carbon emission also depends on other variables such as
driving style, road condition, and distance traveled.
In this research, carbon emission from the estimated distance each day obtained
from the interview session from respondents is about 21.52 kg CO 2 . After the actual
distance was taken from the motion study, the total carbon emission was 22.23 kg
CO 2 which is higher compared to the estimated amount. The implementation of
optimization in the GVRP will reduce the carbon emission produced from the waste
collector truck. From the result, the new route selection has the total distance of
74.11 km which gives 15.95 kg CO 2 of carbon emission. The total difference of
carbon emission using the new route is lower than about 28 percent (%) from the
actual route distance by the truck.
12.5 Conclusion
The main goal of this research was to create an efficient management of waste
collection that is cost-effective and lowers the carbon emission which gives benefit to
the organization and environment. Toward the end of this research, it gives the better
route selection using an optimization method and lower carbon emission produced
during the waste collection process. Besides that, the data in this study measured the
actual route used in collecting waste, route schedules, waste collector truck behavior,
and cost projected by the organization in minimizing the cost needed for the operation.
Furthermore, this research will contribute to other organizations and companies that
deal with waste collection in choosing the best route for their activity.
From observation, this research produced a new suggestion of route that can give
less carbon emission and cost reduction. This research can be applied to other areas
of study such as industrial management, supply chain management, transportation
