Abstract

Watu Ulo Beach serves as a vital hub for fishing communities, supplying resources for sea fishing and serving as a landing point for catches. The local government plans to construct a fishing port at Watu Ulo to enhance facilities for fishermen. This study assesses the financial feasibility and sensitivity of investing in the port's construction, considering three income scenarios: pessimistic, moderate, and optimistic. Financial analysis using NPV, IRR, BCR, and PP methods deems the project feasible for moderate and optimistic scenarios, but not for the pessimistic scenario due to IRR (6.15%) < MARR (7.72%). Sensitivity analysis reveals that revenue sensitivity is critical for all scenarios, with the investment becoming unfeasible if revenue falls below certain thresholds: -13.67% for pessimistic, -39.96% for moderate, and -40.75% for optimistic scenarios. Operating cost sensitivity is also crucial, rendering the investment unfeasible if costs deviate beyond specific thresholds: -15.96% for pessimistic, +22.67% for moderate, and 25.59% for optimistic scenarios.

Abstract

The wheat silo and pellet silo structure repair project phase 3 by PT. ISM Bogasari Surabaya is an annual infrastructure maintenance and strengthening activity to support the smooth production process. For this reason, it is very important to be completed on time according to the contract in order to proceed to the next stage of repair and not experience delays that can result in cost overruns. In this study using EVM (Earned Value Method) analysis in overcoming these problems to determine the cost and time performance of implementation as the project progresses and the indicators used in the analysis include SV (Schedule Variance), CV (Cost Variance), SPI (Schedule Performance Index), CPI (Cost Performance Index), which aims to obtain the results of the calculation of ETC (Estimated To Complete) & EAC (Estimated At Complete) in the project completion cost forecast. While ETS (Estimated Temporary Schedule) and EAS (Estimated All Schedule) for project completion time forecast. Based on the results of the cost & time performance analysis carried out up to week 48, the CPI> 1 value shows that the project is experiencing savings and for time performance shows the SPI < 1 value, which means that the project is experiencing delays.

Abstract

Road development in Sampang Regency is carried out based on the Vision and Mission of the 2019-2024 RPJMD, as stated in Mission point 3 Infrastructure: "Improving Quality and Sustainable Infrastructure Development." In 2023, the Sampang Regency Public Works and Spatial Planning Office reported that road stability was at 46.54% of the total length of 754.12 km of district roads. This research on the Teuku Umar Road - Rajawali Road Preservation project aims to analyze the calculation of rigid pavement construction thickness planning for a design life of 20 years, and flexible pavement construction using the Road Pavement Design Manual No. 02/M/BM/2017 method. The analysis of calculations for both rigid and flexible pavements uses the Road Pavement Design Manual Method No. 02/M/BM/2017 for a design life of 20 years. The results of this research indicate that the rigid pavement design includes 200 mm thick concrete, 100 mm skinny concrete, and 150 mm class A aggregate LPA. For the flexible pavement, the design includes 40 mm AC-WC Laston, 60 mm AC-BC Laston, and 400 mm class A aggregate LPA.

Abstract

Transjatim Corridor I, which runs the Sidoarjo-Surabaya-Gresik route, serves as a crucial road-based mass transportation system in East Java Province, particularly within the Gerbangkertasusila Agglomeration Area. In 2023, the average load factor for Transjatim Corridor I was 120%, with an average of 5-6 thousand passengers per day. This high demand necessitated the addition of a fleet with luxury services. This study aims to analyze the financial feasibility of investing in Transjatim Luxury Corridor I buses. The investment feasibility is assessed by comparing income and expenditure variables. The analysis employs the NPV, Benefit-Cost Ratio (BCR), IRR, and Payback Period (PP) methods. The initial investment expenditure is Rp. 8,207,989,625. Assuming a load factor of 70%, the revenue for different fare alternatives is as follows: Alternative 1 (Rp. 17,500 fare) generates Rp. 5,723,200,000; Alternative 2 (Rp. 16,000 fare) generates Rp. 5,232,640,000; and Alternative 3 (Rp. 15,000 fare) generates Rp. 4,905,600,000. Based on a 6% discount rate, the NPV for all alternatives is greater than 0: Alternative 1 yields Rp. 5,204,972,631; Alternative 2 yields Rp. 2,466,479,592; and Alternative 3 yields Rp. 640,817,566. The IRR values exceed the discount rate, with Alternative 1 at 19.42%, Alternative 2 at 12.54%, and Alternative 3 at 7.74%. The BCR values are all greater than 1: Alternative 1 is 1.30, Alternative 2 is 1.19, and Alternative 3 is 1.11. The PP values are 4 years for Alternative 1, 5 years for Alternative 2, and 6 years for Alternative 3. Thus, all three alternatives are deemed financially feasible.

Abstract

During peak hour conditions, the traffic orderly area (KTL) in the existing Pahlawan Road area has not provided maximum results regarding performance and traffic order. The solution to the transportation problems that occur is to assess the performance of related sections and intersections and analyze the selection of traffic handling schemes to produce the most effective and efficient handling output. The purpose of this study is to determine the most optimal traffic engineering management recommendations for Pahlawan Road, Sidoarjo Regency. In data processing, researchers analyzed survey data, including the analysis of the traffic trip destination-origin matrix, vehicle free speed, vehicle behavior, and intersection control. The authors calibrated and validated the simulation model using the Vissim application, which represents the real situation in the field. Analysis of the traffic performance of the existing condition of the Pahlawan Road area road network revealed an average delay of 96.5 seconds, an average vehicle speed of 23.7 km/h, a total vehicle travel time of 1,691.6 hours, and a total vehicle delay of 725.2 hours, indicating poor road network performance. To improve the performance of the road network on the Pahlawan road section, the authors developed six road network simulation scenarios to derive the most optimal traffic engineering management recommendations for Pahlawan Road, Sidoarjo Regency.
