Abstract

The continued increase in the number of motorized vehicles each year, at a growth rate of approximately 4.6%, is a strong indication that the public's mobility needs are not being met by adequate public transportation services. The purpose of this study is to develop an optimal Bus Rapid Transit (BRT) operational plan for the Porong-Pasuruan corridor and to analyze the financial feasibility of implementing it. The BRT service operates from 5:00 AM to 9:00 PM (16 hours). The total route length is 33.4 kilometers per hour. The planned operating speed is 30 kilometers per hour, resulting in a travel time of 66.8 minutes. The round-trip travel time is 143.6 minutes. The vehicle headway is 14.65 minutes. The trip frequency is 4.1 vehicles per hour. The cycle time from A to B and back to A is 153.62 minutes. The number of trips per vehicle is 6 trips, and the fleet requirement is 10 vehicles. The benefit-cost ratio (BCR) calculation yields a value of 1.10. A BCR value > 1 means that the Porong-Pasuruan corridor Bus Rapid Transit (BRT) implementation project is declared feasible because the total benefits are greater than the costs incurred

Abstract

This study aims to analyze the factors influencing the Detailed Engineering Design (DED) Development Performance for the West Muna Regency Regional General Hospital (RSUD) construction project using the Design and Build method, as well as the implications of these dominant factors on project implementation time. The research variables consist of Basic Design Quality (X1), Compliance Level with the DKPPK (X2), and Conformity to Field Conditions (X3) on DED Development Performance (Y). Data were obtained from 31 respondents consisting of the PPK (Commissioner of Works), the Ministry of Health Technical Team, Construction Management Consultants, Design Consultants, and Design and Build Service Providers. The CPM analysis results indicate a project completion duration of 343 days, a 48-day deviation from the remaining contract duration of 295 days. The project's critical path consists of planning and permitting, foundations, earthworks, floor structures 1–3, floor architecture 3, attached interiors 3, loose furniture 3, testing and commissioning, and handover. This study concludes that suitability of field conditions is the most dominant factor influencing the performance of DED development and has direct implications for achieving project implementation timelines
