Abstract

Occupational safety and health are crucial aspects in the implementation of construction projects, especially large-scale projects such as the construction of the Workshop Building in Cikarang. Workplace accidents that still frequently occur on-site highlight the importance of evaluating the implementation of the Occupational Safety and Health Management System (OSHMS). This study aims to measure the level of OSHMS implementation, identify the barriers to its implementation, and evaluate the strategies used to overcome these barriers. The method used in this study is descriptive evaluative with a quantitative approach, where data was collected through the distribution of questionnaires to 80 respondents consisting of workers and project management teams. The research instruments were tested using validity and reliability tests, and the results were analyzed using mean calculations and the Relative Importance Index (RII). Data was processed using SPSS software. The research results indicate that the level of SMK3 implementation is in the “Very Good” category, with the highest average score of 4.7 and an RSI of 0.94 on the indicator of understanding and implementation of safety procedures. The obstacles faced were categorized as “Less Hindering,” with the lowest average score of 1.89 and an RSI of 0.38 related to management commitment to SMK3. Meanwhile, strengthening strategies such as safety briefings and SOP evaluations were categorized as “Very Effective,” with the highest average score of 4.63 and an IKR of 0.925. The conclusion of this study is that the implementation of SMK3 in this project has been optimal, with minimal obstacles and effective control strategies

Abstract

Medan City as a metropolitan city has a high level of urbanization, a significant growth rate and a continuously increasing volume of vehicles every year. This causes traffic congestion, increased travel time and energy waste. Due to these problems, the Medan city government uses Bus Rapid Transit (BRT) to reduce the congestion that occurs. The operational performance and quality of BRT services are the main keys to attracting people to switch from private vehicles to public transportation. This research was conducted on the Trans Medan BRT Corridor K2 J-City – Merdeka Square. Data collection was carried out by field surveys and distributing questionnaires to Trans Medan BRT users and four experts. This study uses the provisions of the Decree of the Director General of Land Transportation No. 687 of 2002, Regulation of the Minister of Transportation of the Republic of Indonesia No. 10 of 2012, Regulation of the Minister of Transportation of the Republic of Indonesia No. 98 of 2013 and The BRT Standard 2016 for operational performance evaluation and uses the customer satisfaction index approach and analytical hierarchy process for service analysis. The results of the study showed an average load factor of 21%, an average travel time of 15.35 minutes, an average waiting time of 7.4 minutes, an average circulation time of 1.2 hours, an average speed of 25.5 km/h and a total score based on The BRT Standard 2016 of 38, which means this corridor has not met the minimum requirements for the bronze-standard BRT category. CSI analysis showed that 85.18% of Trans Medan BRT users felt very satisfied with the quality of service. Furthermore, AHP analysis identified the main factors that influence the priority of Trans Medan BRT service performance, including the ability to provide the best service to passengers, the availability of insurance or safety guarantees, comfort, responsive and appropriate service, and officers ready on site when needed.

Abstract

This study adopts a quantitative case study approach using the Earned Value Method (EVM) to assess project cost and schedule performance, complemented by a Time–Cost Trade Off (Crashing Analysis) to formulate acceleration strategies that restore the project to its planned timeline. Primary data were collected through field observations and interviews, while secondary data were obtained from weekly and monthly reports, the project time schedule, and the Project Budget Plan (RAB). The analysis indicates that the project experienced delays, reflected by by the condition BCWP < BCWS, which reflects schedule deviation. However, cost utilization remains efficient because ACWP < BCWP, indicating that actual spending is lower than the value of work completed. This condition is supported by the cost performance index CPI > 1, which signifies cost efficiency, while the schedule performance index SPI < 1 indicates schedule delays. The estimated cost at completion (EAC), amounting to Rp13,125,412,382.00, shows that the project is expected to finish below the original budget of Rp17,968,594,000.00, whereas the time estimate (TE) shows a potential delay of 11.82 weeks beyond the contract duration. Through crashing analysis, adding 5 hours of overtime per day can reduce the remaining critical path duration from 11.82 weeks to 6 weeks with an additional cost of Rp143,390,625.00, equivalent to approximately 4.3% of the total crash cost.
