Abstract

The aim of the research is to determine the differences in costs and completion times for road and bridge construction projects. The research method used in this study is quantitative research. The difference in normal project work implementation time is 510 working days, after accelerating the work using the time cost trade off method using 2 (two) alternatives, namely additional working hours (overtime) which takes 490 working days, while with the alternative additional labor requires 489 working days. The total cost used before acceleration was Rp. 108,899,888,900 after acceleration using additional working hours became Rp. 100,361,229,776 and saved costs of Rp. 8,538,659,123 and after acceleration with additional workers became Rp. 97,309,953,040 and saved costs of Rp. 11,589,935,859.

Abstract

This study aims to determine the influence of work experience and incentives on the supervision performance of the Sultan Hasanuddin Airport development project in Makassar. A quantitative approach was employed, with data collected through questionnaires distributed to all supervisory consultants involved in the project, totaling 25 respondents. The data were analyzed using multiple linear regression, preceded by classical assumption tests, including normality, linearity, heteroscedasticity, and autocorrelation tests, to ensure the validity of the model and to examine both the simultaneous and partial effects of the independent variables (work experience and incentives) on the dependent variable (employee performance). The results indicate that work experience and incentives have a positive and significant effect on the supervision performance of the Sultan Hasanuddin Airport development project. The coefficient of determination (R²) value of 65.8% shows that both independent variables collectively explain the variation in supervision performance, while the remaining 34.2% is influenced by other variables outside this regression model or not examined in this study. These findings highlight the importance of work experience and the provision of incentives in improving the supervision performance of construction projects, particularly in the development of Sultan Hasanuddin Airport, Makassar.

Abstract

Traditional market waste is an environmental issue that requires planned and sustainable management. This study aims to determine the volume of waste generation and identify the activities that predominantly produce waste at Pasar Induk Minasa Maupa, Gowa Regency. A descriptive quantitative approach was employed through direct observation, waste volume measurement, and interviews with vendors and sanitation workers. Data were analyzed to calculate the waste generation volume per business category and the composition of organic and inorganic waste. The findings revealed that the total daily waste generation reached 15.174 m³, consisting of 51.4% organic waste (191.3 liters/day) and 48.6% inorganic waste (180.7 liters/day). The activity that predominantly generated organic waste was street vendors (PKL) with 71.7 liters/day (37%), while inorganic waste was mainly produced by kiosks/lods with 89.3 liters/day (49%).

Abstract

The procurement and installation of the Baggage Handling System (BHS) at Sultan Hasanuddin International Airport is a strategic project with high complexity. Common challenges faced in such projects include schedule delays and cost overruns, making it necessary to apply an evaluation method that provides a comprehensive picture of project performance.This study applies the Earned Value Management (EVM) method, which integrates cost, time, and work progress. Data were collected from the baseline schedule, S-curves, and weekly progress reports. The analysis was conducted by calculating the main EVM indicators (BCWS, BCWP, ACWP) and derivative measures such as CV, SV, CPI, and SPI, along with completion forecasts using Estimate at Completion (EAC) and Estimate at Schedule (EAS).The results show that the Schedule Performance Index (SPI) < 1 indicates project delays, while the Cost Performance Index (CPI) > 1 reflects cost efficiency. Although project costs are under control, the estimated completion time is likely to exceed the contractual schedule. Thus, EVM proves to be an effective tool for evaluating project performance and supporting strategic decision-making in construction project management
