| dc.description.abstract | PT Pertamina Lubricants is a sub-holding company engaged in commercial
and trading activities with its main business being the production and marketing of
lubricant products. In order to support its marketing activities, PT Pertamina
Lubricants has collaborated with PT Patra Logistik to distribute its lubricant products.
However, during the distribution process of lubricant products in the Jabodetabek
area, a problem was identified, which is the underutilization of the fleet, leading to
some vehicles being idle during working hours. This research aims to address the
issues faced by PT Pertamina Lubricants by using the Multi Trip Heterogeneous Fleet
Green Vehicle Routing Problem with Time Windows (MTHRFGVRPTW) method,
which will be implemented in the distribution of lubricant products in the Jabodetabek
area. The purpose of this model is to enhance resource efficiency and reduce
environmental impacts during the delivery process. The optimization method based on
Geographic Information System (GIS) is used to solve this problem by considering
factors such as permintaan, closest distance, capacity, operational time windows of
depots and distributors. The data processing involves three scenarios to be resolved:
Scenario 1 with a fleet speed of 40 Km/h, Scenario 2 with a fleet speed of 50 Km/h,
and Scenario 3 with a fleet speed of 60 Km/h. ArcGIS 10.8 is utilized to assist in the
data processing. Based on the results of data processing, each scenario has achieved
optimal outcomes. For example, in Scenario 1 during the month of January, the
MTHRFGVRPTW model successfully completed the distribution for January with a
total permintaan of 678 KL in just 6 days, using 3 units of Wing Box trucks and 1 unit
of Colt Diesel Double truck, compared to the previous distribution process that took
more than a month. | en_US |
