Abstract

PT. XYZ is an agro-business company in Gresik, East Java, which is currently in the factory construction stage. Field obstacles often occur, so the process of conveying information from all stakeholders involved is important. The author will evaluate communication management factors that influence project success using EFA-Maximum Likelihood and Spearman's rank order correlation. This analysis identified nine important factors: information technology, communication technology, communication skills, communication management plan, teamwork, clear channels in the organizational structure, project requirements management, project risk management, and environmental context. The language acquisition factor was excluded because it did not meet the EFA requirements. Spearman's rank order correlation shows that information technology, communication skills, communication management plans, teamwork, clear channels, project requirements management, and environmental context have a strong relationship with project success. These findings guide improving project communication management to achieve project success.

Abstract

Indonesia's construction industry faces challenges in maintaining quality while optimizing costs, especially in the selection of formwork methods that greatly affect the quality of concrete structures and overall project efficiency. This study aims to analyze the implementation of Cost of Quality (COQ) in conventional and semi-system formwork for the KIPP Continuation Dam and DAS Pemaluan project. The research method uses a comparative quantitative approach with COQ analysis covering prevention, appraisal, internal failure, and external failure costs. Results show that conventional formwork COQ is 87.14%, dominated by internal failures (43.54%) due to vulnerability to installation errors and material damage. Meanwhile, semi-system formwork COQ is 21.77% with a more balanced distribution between prevention costs (44.04%) and internal failures (15.62%). Technical planning shows conventional formwork requires support spacing of 170mm, horizontal supports 810mm, and braces 690mm, while semi-system requires 250mm, 900mm, and 1065mm respectively. Although conventional formwork material costs are 63% cheaper than semi-system, the high total quality costs make semi-system more efficient overall with more consistent performance and minimal rework risks.

Abstract

Post-disaster infrastructure reconstruction presents unique challenges, requiring adaptive construction methodologies to address altered geological conditions and optimize resource utilization. The reconstruction work of the Gumbasa irrigation system after the earthquake, tsunami, and liquefaction disasters experienced obstacles in the implementation of the primary channel due to sandy soil conditions that are prone to landslides. The initial design, using precast shoes, was delayed and over budget due to difficulties during field installation. This study applies the value engineering method to evaluate the potential for cost savings and functional improvements through the analysis of work methods and primary channel design. Quantitative and qualitative approaches are used, with stages including information gathering, function analysis, creative ideation, evaluation, and recommendations. The results showed that the cast-in-situ method was superior, achieving a total cost efficiency of IDR 1,062,223,159, or 1.4% of the initial budget. In the lining shoe item, the savings reached IDR 3,397,623,506, or 29.7% of the initial work value. The project duration decreased from 456 days to 240 days, with a time saving of 216 days, or 47.4%. Evaluation of Value Engineering Potential in Work Methods and Design of the Primary Canal in the Post-Disaster Gumbasa Irrigation Project has proven to be effective in assessing post-disaster infrastructure implementation by providing added value in terms of cost, quality, and time.

Abstract

Port infrastructure projects face unique challenges in maintaining operational continuity while executing complex structural modifications, especially in terminals operating 24 hours with strict time and technical constraints. The berthing reinforcement project at XYZ Container Terminal aimed to accommodate container ships up to 100,000 DWT and support the Super Post Panamax Quay Container Crane. Scheduled for 297 days, the project is located at an operational berth. During implementation, disruptions caused a -6.853% deviation in achievement weight in week 8 and risked delays. This research analyzes acceleration methods using the Critical Path Method, comparing Fast Track and Crashing techniques. Quantitative analysis with Microsoft Project includes adding drilling machines, adding labor (Crashing), and adjusting the Partial Hand Over (PHO) stages (Fast Track). Fast Track with PHO 2 stages accelerated completion to 296 days (0.34%) with a 0.10% cost increase; PHO 3 and 4 stages shortened it to 295 days (0.67%) with a 0.21% cost increase. Crashing shortened completion to 285 days (4.04%) but increased costs by 0.13%. The 4-stage PHO configuration shows superior operational efficiency by segmenting work areas to minimize disruptions, achieving faster completion than planned, and meeting Box Per Ship Per Hour (BSH) targets with minimal extra costs. This research offers a practical framework for selecting acceleration methods in port infrastructure projects requiring phased handovers and workspace optimization.
