Abstract

Padang City has experienced rapid development in infrastructure, but the limited green open space presents a significant challenge to the city's drainage system, resulting in frequent flooding during the rainy season which has a negative impact on the economy, health, and safety of the community. This study aims to identify the intensity of rainfall, analyze the implementation of Low-Impact Development (LID) technology and without LID implementation using EPA SWMM 5.2 software in the DPR Street area, Dadok Tunggul Hitam Village, Padang City. The practical implications of the implementation of Low Impact Development (LID) for general city management are to reduce drainage loads by managing rainfall locally, improve water quality by reducing rainfall pollution, reduce flood risks by managing rainfall effectively, improve city aesthetics by creating green and beautiful open spaces, and reduce infrastructure costs by managing rainfall locally and reducing the need for large drainage systems. The main benefits of the research results for flood management policies in Padang City are to improve the quality of life of city residents by creating a healthier and more comfortable environment, increase city resilience to climate change and natural disasters, and improve resource management efficiency by managing rainfall locally. Using 10 years of rainfall data from BMKG and primary data related to drainage channel dimensions, hydrological and hydraulic analyses and drainage system simulations were carried out. The results of the study showed that the application of LID, such as Rainfall Garden, Rainfall Barrel, Bioretention Cell, Infiltration Trench, and Permeable Pavement, application of LID an area can reduce the depth of inundation by 57,717%, the volume of runoff by 74.247%, and the peak runoff by 68,069%. The implementation of LID in an area of ​​73.54 Ha has proven effective in reducing the risk of flooding, strengthening drainage infrastructure, and providing sustainable solutions in dealing with urbanization in Padang City.

Abstract

Late payment is a common problem that often occurs in construction projects and can hinder project completion. Previous studies have stated that factors that influence late payment include the financial condition of the project owner and poor business management as well as delays in payment by the project owner and others. Previous studies only discussed the factors that cause late payment. This study aims to identify factors that influence late payment and find solutions to overcome them. The research method used is qualitative with in-depth interviews with parties involved in construction projects, such as PPK and Contractors. Data were processed using interview transcripts and analyzed with thematic analysis to identify emerging patterns or themes. The results of the study indicate that the procedures for implementing payments have been regulated in contracts and related regulations. Factors that cause late payment include poor communication, administrative negligence, empty regional treasury, and unclear regulations. The proposed solution is to conduct training for HR and hold daily or weekly meetings involving all related parties. This research is expected to contribute to increasing payment efficiency in construction projects. This study has limitations, namely the lack of quantitative data and local context, limited samples, focusing on internal factors.

Abstract

This study evaluates the success rate of the program (target accuracy, satisfaction, and community self-reliance) of the special allocation fund (DAK) self-help housing assistance in Pariaman City, a coastal area with a majority of low-income residents and many uninhabitable houses. This program is part of the government's efforts to overcome poverty and deal with slum areas, as stipulated in the Minister of PUPR Regulation No. 7 of 2022. Previous studies may have only focused on one or two dimensions. This study uses a mixed method of quantitative and qualitative. Quantitative data were collected through a questionnaire with a Likert scale to measure target accuracy, satisfaction, and community self-reliance. Qualitative data were collected through in-depth interviews with beneficiaries and related parties to understand their context and experiences related to the program. Data were analyzed quantitatively using descriptive statistics and qualitatively using thematic analysis. The results showed that the program was right on target (more than 80% of respondents gave the highest score), the level of satisfaction was high (more than 70% of respondents gave a score of 4 or 5), and community participation was very good (84.29% of beneficiaries were involved in house construction on average). These findings provide strong empirical evidence of the success of the DAK self-help housing assistance program in Pariaman City. The local government can use the results of this study to strengthen the DAK self-help housing assistance program, for example by increasing budget allocation or expanding the reach of the program.

Abstract

The new technology that is being developed is porous asphalt pavement structures, which are made for road segments with less dense traffic. This structure is designed to include facilities such as parking lots, bicycle lanes, pedestrian sidewalks, and tennis court areas. This study involves the analysis of calculation results based on secondary field data and experimental data from laboratory-scale experiments. The design of the road pavement is based on the AASHTO 1993 method. The field data used includes information on the LHR (Load History Record) of the Dawuan Highway (Cikampek) section, the CBR (California Bearing Ratio) value of the subgrade, and the existing pavement conditions (including existing pavement structures and deflection data). Meanwhile, experimental data comes from testing the resilient modulus of porous asphalt mixtures using Cariphalte asphalt and additional gilsonite material with optimal levels. The resilient modulus value was obtained from laboratory testing using the Universal Material Testing Apparatus (UMATTA). The results of this study produced a pavement design using a gilsonite mixture that produced a thinner thickness than standard AC-WC materials. For example, for segment 3 with a modified mixture, the pavement thickness is 13 cm, while the standard AC-WC produces a thickness of 20 cm. It can be seen that using a modified Gilsonite mixture requires an overlay layer 7 cm thinner than using a standard AC-WC mixture.

Abstract

Every construction project, in general, has a specific and systematic method implementation program, such as the utilization of heavy equipment in girder erection work. This focus is selected based on the high technical complexity of girder erection work, so the productivity of heavy equipment greatly affects the work's success. The aim is to analyze the suitability between theoretical calculation of crawler crane productivity and direct observations in girder erection work and identify the factors that cause the productivity difference. This study combines the theoretical calculations and direct observations to evaluate the productivity of crawler cranes in girder erection work. Based on theory, the method of calculating crane productivity is done by analyzing the operating cycle time and productivity of crawler cranes. With the direct observations method, actual data is taken in the field, which is then calculated as the result of its productivity. From the results of this study, it is found that the results of crawler crane productivity in direct observation in the field have a higher productivity value compared to the productivity value in theoretical calculations, namely 1.51 units/hour, while in theoretical calculations, the productivity value is 1.060 units/hour. The difference in value is caused by several factors in the field, such as weather conditions, operational obstacles, and the operator's efficiency.

Abstract

This study analyzes the risks associated with under bid price contracts on construction projects in West Sumatra, a phenomenon that shows a significant increase from 7.28% in 2015 to 32% in 2020. This study is focused on the local context of West Sumatra, providing new insights into competitive dynamics and business practices that may be unique to this region, in contrast to previous studies that may be general or regional in nature. The research objective is to identify and analyze the risk factors that arise from this under bidding practice. Through a specially designed questionnaire survey distributed to 30 local contractors in West Sumatra, and data processing using the SIRISPRO application, this study quantified and identified three main risks: specification deviations and design changes, contract criticism, and price increases during execution. The results showed that contractors responded to these risks by conducting evaluation and inspection of specifications, correction of deviations, and evaluation of personnel and acceleration of work. The implication of these findings is the need to evaluate government project contract management policies, particularly related to bidding regulations and more comprehensive bid evaluation, to mitigate the risk of under bidding and ensure the sustainability of quality construction projects in West Sumatra.

Abstract

This study investigated the flow and sedimentation patterns at a series of check dams on the Kuranji River. A physical model was built in the laboratory at a specific scale to simulate field conditions. The models were built using an approach to existing conditions with a dam height scale of 1:125 while the check dam spacing was 1:300 while the field condition spacing between check dams of scenario 1 (89.00 cm), scenario 2 (94.00 cm), scenario 3 (200 cm). All models were conducted in a 40 x 40 cm rectangular open channel in the laboratory of Fluid Mechanics and Hydraulics, Faculty of Engineering, Andalas University, Padang. Sediment material was used from the Kuranji Trunk. Furthermore, each experiment with variations in flow discharge was observed and measured the sediment distribution pattern before and after the check dam building. From the test results, it was found that the sediment balanced condition ranged from 10-19 minutes after the water came out of the dainhole. Sediment distribution patterns are influenced by two main factors, namely the distance between check dams and flow discharge. The use of too far a distance results in sediment having a greater chance of moving away downstream, on the other hand, with a close distance between check dams, the sediment distribution moves not too far. Discharge variations affect the scouring depth. The greater the flow discharge, the greater the energy to scour and carry the greater sediment.

Abstract

This study evaluates the effectiveness of risk management implementation in national road infrastructure projects managed by the National Road Implementation Agency (BPJN) of West Sumatra, Indonesia. Employing an evaluative method that integrates qualitative and quantitative approaches, this research assesses risk management practices based on the guidelines set by the Ministry of Public Works and Housing. The study utilizes document reviews, structured interviews, and perception surveys involving at least 10 respondents, including Risk Owners, Risk Managers, and officials from the Risk Management Unit (UPR) responsible for planning, financial management, and technical operations. Findings indicate that while BPJN West Sumatra has effectively implemented several risk management aspects, deficiencies persist in risk monitoring and response strategies. Notably, the study highlights the urgent need for a structured risk monitoring system, more proactive mitigation strategies, enhanced stakeholder communication, and the integration of information technology. This research contributes to the existing literature by providing a comprehensive evaluation framework for risk management effectiveness in infrastructure projects, offering practical recommendations to improve risk management capacity and support the successful execution of national road infrastructure projects in West Sumatra.

Abstract

This study compares evapotranspiration (ETo) values obtained from direct field observations with estimates from empirical models at different elevation. The empirical models used are Modified Penman, Penman-Monteith, Blaney-Criddle, Hargreaves, and Radiation. This research was conducted in the Batang Kuranji Watershed, specifically in Pauh Subdistrict (174 m above sea level) and Nanggalo Subdistrict (18 m above sea level), from August 6th to August 31st, 2023. Daily temperature, humidity, wind speed, and solar radiation data, collected using Thermo-Pro devices and from relevant agencies, were used as input for the empirical models. Three field experiments were carried out in the form of: evaporation plots, evapotranspiration plots without infiltration influence, and evapotranspiration plots with infiltration influence. Furthermore, the observed ETo values in the field were 90.67 mm/month in Nanggalo and 90.00 mm/month in Pauh. The empirical models produced estimates comparable to field observations. Analysis of the coefficient of determination (R²) revealed that the Modified Penman empirical model was the most suitable with field experiments and showed a very strong relationship (R² = 0.96). The results of this study can be used as a basis for managing rice irrigation water and developing better ETo prediction models, especially in the Batang Kuranji Watershed. The authors identify areas needing further research to enable the model's use for calculating evaporation across an entire growing season.

Abstract

Construction services play a crucial role in national development, and providing Safety, Health, and Sustainability (K4) standards is an important aspect in its implementation. This study aims to channel the level of provision of K4 standards in building construction in Padang City from the perspective of stakeholders (Project Owners, Supervising Consultants, and Contractors), and identify areas that need improvement. This research method uses a qualitative approach with semi-structured interview techniques. Interviews were conducted in depth with representatives from each stakeholder to explore information on the understanding, implementation, and challenges related to K4 standards. Data analysis was carried out descriptively qualitatively by identifying themes that emerged from the interviews and comparing them with the applicable K4 standards. The results of the study indicate that the level of provision of K4 standards in building construction in Padang City is not yet optimal. Of the eight criteria containing K4 standards, there are three standards that have been 100% met (material quality standards, quality standards for the results of construction service implementation, and social protection guidelines for workers). However, there are five standards that still need to be improved, namely equipment quality standards (87.50%), occupational health and safety standards (84.37%), construction service implementation procedure standards (97.22%), operational and maintenance standards (66.67%), and environmental management standards (91.20%). The novelty of this study lies in its focus on the stakeholder perspective in evaluating K4 standards. Previous studies tend to view K4 standards from only one perspective, so this study provides a more comprehensive picture. In addition, this study also specifically identifies areas that need to be improved, so that they can be the basis for implementing more effective construction policies. The practical implications of this study are recommendations for more comprehensive construction policies to improve the provision of K4 standards. Local governments and construction associations can use the results of this study to develop more effective training, socialization, and supervision programs. In addition, this study can also be a reference for construction actors to increase awareness and compliance with K4 standards.
