Abstract

Water stored on the surface generally turns into runoff and much faster than groundwater considering the very low flow rate of the latter. Drainage of the Pondok Jati residential area is less able to receive or accommodate rainwater discharge because the development and growth of a city is one of the triggers for increasing the volume of discharge that passes through the residential area. Land use will affect the percentage of water that seeps into the soil with surface flow. Land with dense populations and many buildings, infiltration wells must be made more and larger in volume. Either with individual infiltration wells or with infiltration wells collectively for several houses, the need for infiltration wells from each block to reduce runoff that occurs with a 10-year return period plan. For the specifications of this infiltration well, concrete pipes are used. This infiltration well itself has concrete pipe walls with a diameter of 100 cm (1 meter) with the depth of the infiltration well is 300 cm (3.0 meters) and the number of points needed. The cost of making an infiltration well with a total of 210 infiltration wells in the Pondok Jati Sidoarjo housing complex is Rp. 696.358.600,- .

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.

Abstract

The Reconstruction Project of Penganten-Ngampal Road in Bojonegoro Regency faces challenges in time and resource management, leading to project delays. These delays affect time and cost efficiency, which are key issues in achieving the project's objectives. To address this problem, this study aims to analyze the project’s work schedule and critical path using the Critical Path Method (CPM). The research employs a quantitative method, with data collected through primary and secondary data sources. Primary data was obtained through field observations and questionnaires, while secondary data was gathered from project documents and relevant literature. Using CPM, the first step was to construct the project’s work schedule based on the work breakdown structure (WBS) and the relationships between activities. An analysis was then performed utilizing forward pass and backward pass methods to identify the critical path. This path comprises tasks that require timely completion to avoid causing additional project delays. The results show that the critical path for the Penganten-Ngampal Road Reconstruction Project is identified in activities with codes A, C, D, E, and F. The total project completion duration based on the analysis is 47 days. Activities on this critical path must be completed on time, as delays in any of these activities will affect the overall completion of the project. Therefore, better time management and proper resource allocation for critical activities are essential to complete the project according to the planned timeline.

Abstract

HIV/AIDS, an extremely harmful sexually transmitted disease, has had a significant impact on worldwide health, establishing itself as one of the most lethal epidemics ever recorded. In this study, a mathematical model is used to analyze how HIV/AIDS spreads and grows, taking into account high incidence rates. The model uses a set of typical differential equations to group people into different categories based on their health status, including those who are vulnerable, those who have been vaccinated, those who are asymptomatic, those who are symptomatic, and those who have AIDS. The effectiveness of the solution indicates that the model is clearly outlined and has important implications for epidemiology. By utilizing the next-generation matrix method, we calculated the basic reproduction number. In order to evaluate the model's stability, a comprehensive examination was conducted on both the local and global stability of both the disease-free and endemic equilibrium points. This analysis provides a comprehensive understanding of the model’s behavior, shedding light on the conditions necessary for the disease to persist or die out. Numerical simulations focusing on these key parameters demonstrate that achieving a disease-free environment is attainable, albeit requiring targeted interventions to maintain stability. This study underscores the significance of understanding saturated incidence rates in modeling HIV/AIDS transmission dynamics. The results offer important information for policymakers and public health authorities, allowing them to create successful tactics for managing the transmission of HIV/AIDS.

Abstract

Organic carbon availability is crucial for effective soil capability, suitability, and fertility potentials, which makes it a serious consideration among all soil parameters in the evaluation of soil nutrient availability and general carbon sequestration. This research article explored an appraisal of soil organic carbon content availability across diverse vegetation covers in Delta State, Southern Nigeria, including lowland rainforests, secondary regrowth, and wet grasslands. The study aimed to establish whether significant differences exist in organic carbon availability across the landscapes to determine soil suitability for functional utilitarian purposes. The methodology adopted was strictly a field survey where soil samples were collected in situ across the three different landscapes at depths of 0-15 cm (not meters), which is the zone of nutrient uptake and activity. A total of 90 samples, with 30 collected from each landscape, were drawn based on systematic stratification. The one-way ANOVA revealed no significant difference in soil organic carbon content across the studied landscapes (p = 0.54, p > 0.05), leading to the acceptance of the null hypothesis. This indicates that the landscapes share similar soil fertility and nutrient availability, supporting their equal suitability for agricultural uses, particularly for arable crop production and precision farming in wet grasslands.
