Abstract

As one of the largest cities in Indonesia, the City of Surabaya has an obligation to provide excellent health services for its residents. It goes without saying that Surabaya City Government is required to provide a General Hospital that can receive referrals from the government-owned Community Health Centers. For this reason, the Surabaya City Government built the East Surabaya Hospital which is located in Rungkut Sub-District. East Surabaya Hospital is a strategic project that requires investment feasibility analysis. The East Surabaya Hospital investment feasibility analysis was done by applying the Net Present Value (NPV), Internal Rate of Return (IRR), Payback Period (PP) and Benefit Cost Ratio (BCR) parameters. After the feasibility analysis results were obtained, a sensitivity analysis was done on changes in management costs and the amount of health service levy rates for each Fees alternative. Based on the results of the investment feasibility analysis of 4 (four) Fees alternatives, there are 2 alternatives that can be concluded as worthy investments, which are alternative 1 and alternative 3. Meanwhile, alternative 2 and alternative 4 are not feasible since the NPV parameter shows negative values and the IRR value is lower than the MARR value. However, based on sensitivity analysis, alternatives 2 and 4 can be feasible if alternative 2’s service rate is increased by 13.2%, and alternative 4’s service rate is increased by 2.3%. The opposite applies in alternative 1 where the investment might become unfeasible if the service rate is reduced by more than 5.4% and alternative 3 might become unfeasible if the service rate is reduced by more than 2.5%.

Abstract

The Durenan - Prigi road section is a 30.4 km long road that is authorized by the East Java Provincial Government, this road is one of the access roads to Prigi Beach, Mutiara Beach and other tourist attractions in Trenggalek Regency. The road that is the access to the tour certainly requires care and maintenance to always be in steady condition and does not reduce the comfort of road users. Factors that cause damage include traffic load factors, soil condition factors, weather, rain, drainage channel factors and so on. In monitoring road conditions, there is a road condition assessment, namely the Surface Distress Index (SDI) method. The objective of this research is to evaluate the condition of the Durenan-Prigi road section using the Surface Distress Index (SDI) method to assess its current state, determine necessary maintenance actions, and estimate the required budget for its upkeep. The SDI method is a method of assessing the condition of the road surface by making visual observations. The SDI method has four types of damage in assessing road conditions with four categories of road condition assessment results. The Durenan - Prigi road section has an average SDI value of 11.89 with an assessment of "Good" condition.  Nevertheless, maintenance is still required with an estimated budget of Rp2,596,960,786.27. The budget includes three main components, namely type 3 emulsified asphalt coating (CQS-1h) amounting to Rp2,392,020,512.39, repairing the cold-applied asbuton mixture amounting to Rp160,955,321.83, and closing type 1 cracks (crack width 0.20-0.50 cm) amounting to Rp43,984,952.06.

Abstract

The construction of retaining walls in Mojokerto Regency is essential due to the region's hilly topography and the increasing risk of slope instability caused by high rainfall and lateral soil pressures. Retaining walls play a crucial role in stabilizing slopes, preventing landslides, and ensuring road infrastructure and mobility are preserved in areas prone to geotechnical challenges. This study focuses on determining the dimensions, costs, and construction timelines of cantilever and gravity retaining walls along the Temuireng-Jetis road section, a strategic route affected by frequent landslides. Using Coulomb's theory and triaxial soil test data, the analysis comprehensively compares the structural stability, safety factors, and economic efficiency of both designs. Results indicate that cantilever retaining walls achieve higher shear stability with a lower construction duration but incur higher costs due to the use of reinforced concrete and steel reinforcements. Conversely, gravity walls are more cost-effective, relying on their own weight for stability, but demand longer construction periods due to their massive size and additional requirements such as drainage systems. These findings contribute to efficient and sustainable infrastructure development, offering practical solutions for areas with varying topographic challenges and soil conditions.

Abstract

Mojokerto, as a key economic center in East Java, faces increasing demands for reliable and efficient road infrastructure to support its economic growth and regional connectivity. The lack of adequate retaining walls along the Bendung-Bantengan road section has resulted in significant road damages, including cracks and subsidence, which pose risks to road users and increase maintenance costs. This study investigates the application of Value Engineering (VE) as a strategic method to enhance the efficiency and cost-effectiveness of retaining wall construction in the area. Using secondary data from topographic surveys and triaxial soil tests, the study evaluates various design alternatives to identify cost savings, stability improvements, and impacts on project duration. The results demonstrate that adopting VE (Alternative 1) reduces construction costs by IDR 284,244,698 through optimized structural dimensions, while maintaining quality and stability standards. Additionally, the project completion period is shortened to 121 days, offering a faster turnaround compared to the initially planned six-month schedule. The findings emphasize VE's potential to optimize material use, minimize waste, and achieve environmental sustainability by reducing carbon emissions during construction. Moreover, VE enables enhanced collaboration among stakeholders, including consultants and contractors, to develop effective and efficient solutions for infrastructure challenges. This research underscores the importance of integrating VE during the planning stages of infrastructure projects, particularly in areas with high erosion risks. By applying VE principles, the Bendung-Bantengan retaining wall project not only meets safety and quality requirements but also contributes to long-term infrastructure resilience and economic efficiency in Mojokerto.
