Abstract
Tembalang District has 206,271 residents, with 156,8 m3 amount of waste generated. Tembalang Sub-District has 18 waste collection point, 23 containers, and 7 transport vehicles to handle solid waste from the waste collection point to Jatibarang Landfill. The percentage of waste transportation services in Tembalang was 27%. There is some waste collection point that has not been able to accommodate waste generation from the Tembalang District residents. Road conditions, road types, and vehicle speeds of the waste transport route affect transporting waste and the remaining work time and the operational costs incurred. This research aims to plan a waste transportation system in Tembalang District by optimizing the work time and cost under the target desired by the relevant department. The average remaining work time is 2.28 hours, with a total of 21 trips/ day. Transportation routes are optimized using Network Analyst on GIS-based applications. Road conditions affect service time with an optimal average speed of 37.607 km h, which causes the addition of the number of trips after optimization increased to 34 trips/day with 31 containers. The average remaining work time is 1 hour. This optimization led to an increase in service percentage to 42%. Vehicle operating costs is increasing each year for about Rp. 694,262,870.53/year with a decrease in the price of fees of Rp. 1,983.59/householder/year due to the rise in service percentage.
Keywords: waste transportation; road conditions; operational time; vehicle operational cost
