Abstract

The high rate of growth of the construction sector in Indonesia has not been matched by its level of success. Problems are still found in many construction projects that result in project unsuccessfulness, including time loss and bad quality work. In order to support the success of construction projects in Indonesia, the aim of this study is to determine the critical factors that influence the success of construction projects in Indonesia. Data collection through questionnaires on 417 respondents who were directly involved in the project. The questionnaire was based on 4 previous studies, measured by a 5-point Likert scale of agreement and consisting of 64 project success variables. The analysis was performed using the Exploratory Factor Analysis (EFA). The results of this study indicate that there are 6 factors that influence the success of construction projects in Indonesia, namely: (1) Factors related to the Project Manager; (2) Factors related to the Contractor; (3) Factors related to Supervisors; (4) factors related to the project; (5) Factors related to Owner; and (6) Factors related to Owner2. Keywords : construction project, project success, critical success factor, EFA

Abstract

Material movement is a significant and costly aspect of gold or general mining projects. This involves the utilization of expensive heavy equipment, necessitating careful management to ensure optimal efficiency. Therefore, this study aimed to analyze the productivity of excavators PC-300 and PC-400 as well as compare theoretical calculation results with actual conditions. The basis was formed by real field data, collected by earthwork supervisors at a gold mine in Indonesia. This data encompassed daily heavy equipment usage, including the duration, the quantity of material moved, and the types of material involved in the relocation process. The calculations resulted in theoretical productivity of 121.45 m3 hour-1 and 99.56 m3 hour-1 for PC-400 and PC-300. Meanwhile, the calculations based on actual conditions resulted in an average productivity of 114.4 m3 hour-1 and 66.3 m3 hour-1 for PC-400 and PC-300 during a one-year project period. The difference between actual and theoretical productivity for PC-400 and PC-300 was relatively small and large at -7.05 m3 hour-1 and -33.26 m3 hour-1, with 0.94 and 0.64 match factors, respectively. The large difference in productivity for the PC-300 was because the equipment supported work projects, such as opening work area access, maintaining area of work, and serving as supporting equipment. Furthermore, it occurred in the total actual production of the material movement against the one-year target production, which was less than -31,921 m3 (-2.5%) out of the 1,277,325 m3 total. The production deficit was attributed to a construction failure that caused PC-400 and PC-300 to be temporarily relocated for reparation. Based on the simulation, target production was achieved by the actual condition at month 13 (additional 1-month duration) with a total production of 1,283,856 m3, which obtained more than +6,531 m3 (+0.51%).
