Optimization of waste transport routes in Pati Regency using ArcGIS

Abstract

Based on the Recapitulation Data of the 2017 Pati District Waste from the Sanitation and Gardening Sector of the DPUTR Pati Regency shows that the amount of waste in Pati Regency is 3,082 tons / day. Meanwhile, the amount of waste transport to sanitary landfill only reaches 320 tons/day. Based on data from the Sanitation Strategy in Pati Regency 2015, Pati Regency Government was able to generate waste transportation service in urban areas by 7.17% and rural areas by 0.87%. This issue not comparable to the area of 1.580,37 km2 with a population density of 785 people/km2. The purpose of this study is to find the optimal value of waste transportation from the existing TTS point and New TTS points to the sanitary landfill by considering the distance and travel time with ArcGIS to improve waste transportation services in Pati Regency. Data collection methods in this study are: first, primary survey with direct interviews with Public Works Agency and Environmental Agency in Pati Regency about waste transportation systems at the polling station point. Second, the secondary surveys related to waste transportation system data namely density points for waste generation, number of garbage trucks and other data related to waste transportation systems. The results show that ArcGIS can help Optimize Travel Time by 39,04% and Optimization of Mileage by 37,38% and the volume of waste transported to reach 2.19% from Temporary Trash Shelter to Landfill.
