Abstract

Jabung District is a sub-district located in the Malang Regency area of 135.89 km2 or around 4.56 percent of the total area of Malang Regency. This sub-district consists of 15 villages, including Argosari, Gadingkembar, Gunungjati, Jabung, Kemantren, Kemiri, Kenongo, Ngadirejo, Pandansari Lor, Sidomulyo, Sidorejo, Slamparejo, Sukolilo, Sukopuro, and Taji. With a population of 74,311 people in 2020, with a population density of 592 people/km2. In Jabung District, especially in 4 villages, including Pandansari Lor Village, Gading Kembar Village, Argosari Village, and Kemiri Village, there is currently a water shortage. Siuk Source Potential has water potential large enough to meet the standard needs in these 4 villages by gravity. From the results of instantaneous discharge measurements during the dry season in 2021, it can be seen that the discharge in Sumber Siuk is 65 l/sec, and the planned collection to fulfill these 4 villages is 20 l/sec. Construction of the broncaptering and raw water distribution network was built in 3 stages. Before the physical implementation of the installation of distribution pipes in stage 3, a trial run was carried out from stage 1 and stage 2.

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.

Abstract

This study aims to identify the priority order for road maintenance on road sections under the Surabaya Road and Bridge Management Unit (UPT PJJ Surabaya) in East Java Province by utilizing the Provincial/District Roads Management System (PKRMS) application integrated with the Analytical Hierarchy Process (AHP) method. Additionally, the study seeks to estimate the required costs for implementing the road maintenance. The research adopts a quantitative approach with a positivist philosophy. The study population consists of 123 employees from the East Java Provincial Public Works and Highways Agency, with a sample of 33 respondents selected using purposive sampling techniques. Data were collected using a mixed-method approach, involving road condition surveys conducted through the Moving Car Observer (MCO) method and a literature review. Data analysis was conducted systematically using a combination of PKRMS and AHP. The results indicate that the top-priority road section for maintenance, based on the integration of PKRMS and AHP, is the Sumberwudi–Karang Geneng section, which obtained the highest Priority Index Score (TPI) of 56. The estimated cost required for maintaining this road section is Rp16,475,545,104.98. The integration of PKRMS and AHP provides an objective, efficient, and data-driven approach, enabling local governments to optimize budgets and extend the lifespan of road infrastructure. This study recommends that local governments consistently adopt the combination of PKRMS and AHP in road infrastructure management to ensure more targeted budget allocation and enhance transparency in decision-making processes.
