Abstract

Roads are vital infrastructure for land transportation and one of the most critical aspects of development in the national and regional economy. According to the Central Statistics Agency for West Papua, the roads successfully built in West Papua Province were only 11,951,592 km until 2017. It comprises 1003.26 km, 2309,648 km, and 8,638,687 km of national, provincial, and regency roads, including Jalan Maruni - Manokwari City Limits. According to the Minister of PU-PR RI, this road type 2/2 UD length is 17.17 km and administratively connects two districts (West and South Manokwari). One of the areas in West Papua Province where the development of infrastructure, investment, and urbanization is very rapid is Manokwari Regency. In line with the change in government status, its development then changed the physical image of the region to become urban. It is because Sorong City has a strategic economic location concerning natural resources, high accessibility, and is the center of the provincial government, thus attracting other financial functions for investment. This movement burdens road infrastructure, and we need several alternative treatments to improve the service of the street segment above. The method is done through surveys of stakeholders on alternative handling, and then the results are analyzed using multiple linear regression. This research is expected to find alternative handling solutions to improve road services in this segment.

Abstract

A problem found in transportation is road narrowing. Road narrowing refers to a condition in which its downstream is smaller than the upstream. This research took place on Ahmad Yani Street at the front of Royal Plaza, Surabaya. The location of this research had a sufficiently high traffic flow. Thus, the road should be able to operate optimally. In fact, there is still a density caused by road narrowing. This research was intended to determine how much the maximum flow, maximum density and free speed on the road before, during and after the narrowing. Besides, this research was carried out to find out the relation of the flow, the traffic density and speed, determine the value of the shock waves during the road narrowing. This research was done on Wednesday and Saturday morning, at 06:00-08:00 and in the afternoon at 16:00-18:00. The calculation performed was based on Greenshield method. The analysis revealed that the largest maximum flow was on the fragment of road before narrowing, which was 2376.30 pcu/hour. The maximum density found on the fragment of road during narrowing was 322.33 pcu/hour, and the highest free speed regarding to the road condition before the narrowing was 57.21 km/hour. The relation between flow, speed and density showed a significant result (R2 0.5). Shock waves obtained were in the mornings and afternoons on Wednesday and Saturday,

Abstract

Sawaibu Bay Bridge is located in Manokwari Regency and is 300 meters long. The west side is on the Jalan Pahlawan canal, and the east is towards Jalan Siliwangi. This study assesses whether the bridge construction project is feasible and finds alternatives or solutions. The analytical methods used are NPV, BCR, and IRR, which refer to the value of inflation by considering the tourist retribution and travel time analysis. The results will be used to conclude whether the first alternative to the project meets the financial feasibility requirements based on inflation. It shows NPV of 67,061,982,402, BCR 1,096, and IRR 30% ? MARR of 10%, which means that the first alternative is feasible to build.
