Abstract

The Reconstruction Project of Penganten-Ngampal Road in Bojonegoro Regency faces challenges in time and resource management, leading to project delays. These delays affect time and cost efficiency, which are key issues in achieving the project's objectives. To address this problem, this study aims to analyze the project’s work schedule and critical path using the Critical Path Method (CPM). The research employs a quantitative method, with data collected through primary and secondary data sources. Primary data was obtained through field observations and questionnaires, while secondary data was gathered from project documents and relevant literature. Using CPM, the first step was to construct the project’s work schedule based on the work breakdown structure (WBS) and the relationships between activities. An analysis was then performed utilizing forward pass and backward pass methods to identify the critical path. This path comprises tasks that require timely completion to avoid causing additional project delays. The results show that the critical path for the Penganten-Ngampal Road Reconstruction Project is identified in activities with codes A, C, D, E, and F. The total project completion duration based on the analysis is 47 days. Activities on this critical path must be completed on time, as delays in any of these activities will affect the overall completion of the project. Therefore, better time management and proper resource allocation for critical activities are essential to complete the project according to the planned timeline.

Abstract

This study aims to identify risks, conduct risk analysis with the severity index method, and determine responses to risks that occur in the implementation of the Bojonegoro Regency Oncology Special Hospital Phase 2 construction work. From the results of risk identification, there are 31 risks grouped into 8 variables. After analysing the data with the severity index method, which is a technique used in calculating the probability value and also the impact, the results obtained were 3 risks in the medium category and 2 risks in the high category. The 5 dominant risks require a risk response. Risk responses to reduce the negative impact of project delays, especially for risks in the high category, include the risk of uncertain weather by planning the scheduling of large works such as casting so that they are not carried out during the rainy season. The risk of unavailability of labour in the field by cooperating with other subcontractors to help complete certain parts of the project.

Abstract

This study aims to analyse the effectiveness of Critical Path Method (CPM) in controlling the time and cost of the Pedestrian Tunnel construction project connecting Joyoboyo Intermodal Terminal with Surabaya Zoo. This project experienced various obstacles such as social conflicts, utility handling, and cross-agency coordination, resulting in delays in implementation. The research used a qualitative approach with primary data in the form of field observations and secondary data from project documents such as schedules, weekly reports, and cost budget plans (RAB). The analysis technique involved identifying the critical path, calculating the activity time, and evaluating the impact of delays on the project schedule. The results showed that the application of CPM was able to identify the critical path that had a direct impact on the project completion time. By knowing which activities have no float time, resource management can be optimised to reduce delays. However, the change in tunnel length from 156 metres to 172 metres affected the total project cost, although the implementation cost on the critical path was maintained.

Abstract

This study aims to determine the priority of road handling in East Java Province by integrating the Provincial/District Roads Management System (PKRMS) application and the Analytical Hierarchy Process (AHP) method. Road condition data is obtained from PKRMS, including the physical condition of the road, traffic volume, and other parameters. The main criteria used in the AHP analysis are road condition, volume capacity ratio (VCR), connectivity, land use and priority areas of East Java Province. Each criterion was assessed and weighted based on its level of importance to produce road handling priorities.  The results showed that the integration of PKRMS and AHP was able to produce a more accurate order of road handling priorities in accordance with strategic needs. In the UPT PJJ Surabaya Road Section, road improvement priorities are arranged based on the Triggered Priority Index (TPI) value obtained from the combined analysis. This research also provides cost estimates for each road section, which helps with more efficient budget planning.  With this approach, it is expected that road management in East Java Province can be carried out more effectively, support inter-regional connectivity, and have a positive impact on economic growth.

Abstract

Infrastructure project delays are often a major challenge in the construction industry, including the Penganten - Ngampal Road Reconstruction project which experienced a 50-day delay from the initial target. This problem is caused by the uncertainty of external factors such as weather and limited resources. This research aims to calculate the probability of success of project completion time using quantitative descriptive method with Program Evaluation and Review Technique (PERT) approach. This method involves three estimates, namely optimistic, most likely, and pessimistic times to evaluate the average duration and critical path of the project. The data used consisted of project reports, field observations, and calculations using POM-QM software. The analysis shows that the project critical path consists of activities A, C, D, E, and F with a total duration of 60 days. The probability of completing the project within 60 days reached 98.21%, showing the effectiveness of the PERT method in managing time uncertainty.

Abstract

The primary objective of this research is to examine the timeline for the construction of a pedestrian tunnel connecting the Joyoboyo Intermodal Terminal (TIJ) with the Surabaya Zoo (KBS). The construction of this tunnel is considered a crucial project aimed at enhancing accessibility and alleviating congestion along the Joyoboyo road. The estimated cost for this project is Rp 31,996,921,529.00 and it is scheduled to be completed within 135 calendar days. The results showed that the main factors of project delays were due to delays in the procurement of 40cm diameter piles, interference due to inundation due to undetected PDAM pipes. Using the CPM method, the identification of the critical trajectory enabled the optimisation of the project duration and reduced the risk of delays. In addition, incremental cost analysis showed the relationship between time acceleration and increased project cost. By identifying key factors causing delays and implementing strategic planning methodologies such as the CPM, the project was able to enhance efficiency and mitigate potential setbacks. Furthermore, the study shed light on the economic implications of time acceleration, emphasizing the importance of balancing speed with cost considerations in construction projects.
