Abstract

This study aims to determine the optimal location of the LRT Musi Emas Feeder stops Corridor 5 in conjunction with the LRT DJKA Station-Plaju Terminal route. Light Rail Transit (LRT) is a rapid transit system that employs an integrated rail crossing model. At present, the LRT remains a primary mode of daily transportation for the residents of Palembang. One of the initiatives undertaken by the government to facilitate the utilization of LRT transportation is the provision of passenger transportation (feeder services). The positioning of the feeder stops remains suboptimal and needs more integration with existing public facilities. The distance between the stop locations is highly variable, with some nearby and others at considerable distances. This issue is addressed through the formulation of the Set Covering Problem (SCP) model, which encompasses the Set Covering Location Problem (SCLP) and Maximal Covering Location Problem (MCLP) models, as well as the development of the Improved SCLP model. The SCP model yields four optimal stop locations, which are significantly distant from the actual conditions at the site. In contrast, the Improved SCLP model identifies 48 optimal feeder stops mapped using Geographic Information System (GIS) software. This map of feeder stops could inform the Palembang City Transportation Agency’s efforts to develop an integrated transportation management system.

Abstract

The purpose of this research is to design and optimize a demand response based-selfish user Cloud Radio Access Network (C-RAN) model to demonstrate with a narrow-minded client utilizing three financing plans specifically level charge, usage-based, and two-part tariff. The Traffic data is classified into incoming data and outgoing data, obtained from a local server in Palembang. The optimal solution is obtained by determining the decision variables and parameters used in each case for all models, compiling improved C-RAN models as many as 2 models, namely model I, and model II, and then determining the optimal solution and sensitivity analysis using LINGO 13.0 software. The most optimal solution is obtained from model II with a flat-fee scheme in case 1 of IDR 3299.7/kbps with 45 iterations. The results of the sensitivity analysis is on the variables ak,m that allows the increase and decrease in the objective function coefficient. At the same time, the value 0 will be constant.
