Abstract

A project of base facility is a kind of routine developing in Indonesian Naval. In this developmentt is necessary to develop methods in measuring performance and evaluating project time through a more accurate critical path feature. The research problem statement is how to evaluate the project schedule related to the time and cost of the Indonesian Navy's facility construction project by conducting a case study as a study for project scheduling at a later stage. The research objective is to identify the critical path of the project through network analysis, determine the factors that cause delays and how to overcome them, and calculate the time effectiveness and cost-efficiency of the project based on the calculation of scheduling acceleration. In this study, project performance measurement was carried out using the Earned Value Method (EVM) and network analysis using the Precedence Diagram Method (PDM). The solution to overcome delays with the crashing project method. The results of the discussion identified 15 critical path activities. The factor causing the delay is the delay in activities on the critical path due to the low level of productivity of the workforce group. The crashing method through additional 2 hours/day overtime can solve the problem of delays so that project implementation can be accelerated from the implementation of 256 working days to 226 working days (11.72% effectiveness) with the initial project cost of Rp. 74,316,727,585.00 reduced to Rp. 72,152,162,704.00 (2.91% efficiency). It will be measurable and reasonable in responsibility when it was suitable with the target. Keywords : Network Analysis, Naval Base, and Project Development.

Abstract

Republic of Indonesia Ship (KRI) Dewaruci is a Naval Academy Cadets' (AAL) training ship that is old. Thiscondition is very susceptible to various threats of accidents while carrying out voyages around the world to cruisethe AAL Kartika Jala Krida Kadet. The government has planned to replace KRI Dewaruci with a new trainingship. This study aims to determine the selection of new prospective makers training ship by the Analytic NetworkProcess (ANP) method. This ANP method is used because the existing data have a relationship among thecriteria and the relationship between criteria and sub-criteria. In alternative selection, there are two main criteria,namely operational requirements criteria with four sub-criteria: security, geographical conditions, skills training,transfer of technology and technical requirement criteria with five sub-criteria: machinery, navigation, trainingequipment, platform, masts, and sails. The results of this study are the alternative priorities for new training shipreplacing the best KRI Dewaruci and also the priority of the main/critical sub-criteria. The biggest alternativescore value is a training ship made by Piere Shipyard made in Spain with a score of 0.50259.Keywords: Analytic Network Process (ANP), Super Decisions, Training ship, Criteria and Sub-criteria

Abstract

ABSTRACT The performance of a project can be assessed based on the aspects of time, cost, and quality. The project is said to be successful when it can achieve the goals in the form of these three aspects by the initial planning. But the reality on the ground, often project implementation is not following the plan, resulting in project delays. Contractors can overcome the delay through various methods of accelerating time. This study aims to determine the acceleration of time through the Time-Cost Trade-Off analysis on The Indonesian Navy Jetty Construction Project in Saumlaki (Phase I) by comparing alternative methods of overtime and additional manpower. The analysis was carried out by using a quantitative descriptive method. The data used is secondary data such as of related documents, Bill of Quantity, S Curve, work volume, list of wages, and a number of workers. The calculation results show that acceleration using overtime alternatives can reduce 18 days or 6.98% of the implementation duration with a reduction in costs of IDR. 1,220,546,167.00 of the total cost of implementation (efficiency 1.8%). Additional manpower can reduce the duration for 19 days or by 7.36% with a reduction of IDR. 1,076,481,972.00 (1.61% efficiency). So that in this study it was found that the alternative of working overtime was more efficient than the alternative of additional manpower. Keywords : Scheduling, PDM, Crashing,
