Abstract

In construction projects, inadequate implementation of the Occupational Safety and Health Management System (OHSMS) poses risks to the safety and well-being of workers, resulting in decreased performance and compromised project quality. This study focuses on the Kapas-Glendeng bridge widening project in Bojonegoro Regency, identifying key obstacles such as workforce competence, limited experience, insufficient training, and challenges accessing digital information. Additionally, issues related to worker involvement in regulation-making, understanding of Personal Protective Equipment (PPE), reporting procedures, and documentation of work accidents were observed. To address these challenges, the study recommends strategies such as involving untrained workers in competence-building programs, providing apprenticeships for less experienced personnel, implementing comprehensive training information systems, actively engaging workers in project planning, enforcing OHS monitoring systems, ensuring mandatory PPE usage with penalties for violations, and establishing clear procedures for recording and reporting work accidents. This proactive approach aims to enhance OHS implementation and mitigate risks in construction projects.

Abstract

The Occupational Safety and Health Management System (SMK3) is a comprehensive framework that is used to regulate various activities and manage occupational safety and health (K3) in a systematic manner. In the context of the Probolinggo Banyuwangi Toll Road Development Project Package 1, the implementation of SMK3 was assessed to determine the level of implementation, identify factors that influenced the implementation, and propose corrective actions. The assessment was conducted based on 166 criteria that were outlined in PP No. 50 of 2012, which is a regulation that governs occupational safety and health in Indonesia. Out of these 166 criteria, it was found that 149 criteria were fulfilled, accounting for a compliance rate of 89.76%. However, there were 17 criteria that were not met, resulting in a non-compliance rate of 10.24%. These non-compliant criteria were categorized as minor issues.Overall, the implementation level of SMK3 in the Probolinggo Banyuwangi Toll Road Development Project Package 1 was deemed satisfactory, as the majority of the criteria were fulfilled. The project also demonstrated adherence to relevant laws and regulations, further confirming its commitment to occupational safety and health. Based on the assessment findings, corrective actions can be proposed to address the non-compliant criteria and improve the implementation of SMK3. These actions may include providing additional training and resources, enhancing communication and coordination among stakeholders, and implementing stricter monitoring and evaluation mechanisms.

Abstract

Research on the Aloha flyover construction project aims to determine the risks that occur in the workmanship of installing steel box girder, knowing the level of risk that occurs in the workmanship of installing steel box girder and knowing how to control the risks that occur in the workmanship of installing steel box girder. The method used in this research is the Hazard Identification Risk Assessment and Risk Control (HIRARC) method guided by the Malaysia HIRARC Guidelines (2008). Starting from identifying hazards at each stage of the work activity, a risk assessment is carried out, the results of which can be used as a reference for risk control, so as to reduce the risk of work accidents. The results of the analysis from the identification of hazards and risks arising in 5 stages of work and a total of 11 potential hazard findings were obtained. (1) Preparation stage for steel box girder erection maneuver; (2) The process of leveling/compacting the erection area soil for preparation of crawler crane footing/foundation; (3) The process of mobilizing steel box girder material from stockyard to erection area; (4) Installing slings + seals that will be used during steel box girder erection; (5) The process of installing steel box girder using crawler crane.

Abstract

As one of the largest cities in Indonesia, the City of Surabaya has an obligation to provide excellent health services for its residents. Consequently, the Surabaya City Government is required to provide a general hospital that can receive referrals from the government-owned Community Health Centers. To fulfill this obligation, the Surabaya City Government built the East Surabaya Hospital, located in the Rungkut Sub-District. East Surabaya Hospital is a strategic project that necessitates an investment feasibility analysis. This analysis was conducted using the Net Present Value (NPV), Internal Rate of Return (IRR), Payback Period (PP), and Benefit-Cost Ratio (BCR) parameters. Following the feasibility analysis, a sensitivity analysis was performed to examine changes in management costs and the health service levy rates for each tariff alternative. Based on the investment feasibility analysis of four tariff alternatives, two alternatives—alternative 1 and alternative 3—were deemed worthy investments. In contrast, alternatives 2 and 4 were found to be unfeasible, as the NPV parameter showed negative values and the IRR value was lower than the Minimum Acceptable Rate of Return (MARR). However, the sensitivity analysis indicated that alternatives 2 and 4 could become feasible if alternative 2’s management cost is reduced by 14.4% and alternative 4’s management cost is reduced by 2.8%. Conversely, alternative 1 might become unfeasible if the management cost increases by 7%, and alternative 3 might become unfeasible if the management cost increases by 3.1%.

Abstract

Electronic media information obtained by the author states that the Mojokerto Regent ordered the Mojokerto District Environment Office to create a Green Open Space that is planned to be built in each sub-district. In 2022, the Mojokerto District Environment Office planned the Sooko Green Open Space by making a DED and continued to carry out its construction and ended at the end of 2023. The research method used is using the method: Net Present Value (NPV) to determine the value of profit or loss, Benefit Cost Ratio (BCR) to determine the comparison of the value of profit and loss, Payback Period (PbP) to determine how long it takes to return the capital that has been spent, and Likert scale calculations to determine how much the level of community satisfaction on the existence of Sooko Green Open Space. The results showed that the Sooko green space development investment is feasible. This can be seen from the NPV> 0 value of Rp 3,213,731,030, the IRR value exceeds the expected interest rate of 22.7%, the Payback Period of returning the investment value of slum housing improvement development occurs in the 4th year 6 months, precisely in 2028. The amount of maintenance costs for the development of Sooko with all facilities and infrastructure is Rp315,291,605, - every year. Based on Excel calculations of the level of community satisfaction from questionnaires that have been obtained, the average value is 90% so that it meets the criteria of Very Satisfied with a standard deviation of 49%.

Abstract

The wheat silo and pellet silo structural repair project Phase III in Surabaya holds great significance for the wheat flour processing industry in Indonesia. PT Indofood Sukses Makmur Tbk Bogasari Surabaya Division, as one of the leading wheat flour producers, required structural repairs on both silos to ensure the smooth operation of the plant and the quality of the final product. Given the importance of time and cost in the success of this project, an effective approach to time and cost management was essential. The project necessitates proper project management to avoid delays and cost overruns, with a budget of IDR 28,011,000,000 and an estimated duration of 455 calendar days. This research employs the Time Cost Trade Off (TCTO) method to analyze options for accelerating project time by considering additional costs that may arise. Microsoft Project software is utilized to identify the critical path, allowing project managers to focus on activities with the greatest impact on the overall schedule. The results indicate that the critical path of the project includes activities such as mobilization and demobilization, administration and reporting, work safety, and repair of the old grain silo. By using TCTO, the project completion time can be accelerated to 359 days from 455 days, reducing the duration by 21.10%.
