Abstract

This research is motivated by the importance of predicting the implementation of a project in the construction field to achieve a success where a project is said to be successful if the project can be completed at a competitive cost, can be completed on time or even faster than the scheduled time, and the quality is achieved. The aim of this study is to determine the critical success factor of government self-management projects (Acceleration Program for Irrigation Water Use Improvement/P3TGAI), so that undesirable things such as cost swells, time delays and others can be predicted as early as possible. This research uses a descriptive method where the populations are community assistance staff (TPM) and Center Management Consultants (KMB) in the program of Acceleration Program for Irrigation Water Use Improvement (P3-TGAI) in the Sumatra V River Basin Center and questionnaires are used as data collection techniques. The results showed that there are 5 determinants of the success of the self-management project for P3-TGAI, such as good communication between parties involved in the project (95.95); appropriate/appropriate work planning (91.89); monitoring of the project by the parties involved (89.19); ability to solve project problems by the parties involved (83.78); proper cost management by the parties involved (83.78). Then, there are 10 aspects that determine the success of P3-TGAI self-management projects, these factors are formed from the highest index in each aspect surveyed.

Abstract

Floods are disasters that disrupt human life caused by human and natural factors. Natural conditions that affect flooding in West Sumatra are rainfall patterns in water areas, sea surface temperature patterns, and whirlpool patterns in the Indian Ocean. Batang Lengayang is a river that is prone to flooding. Floods in the Batang Lengayang river occur every year, especially during the rainy season. According to the Central Statistics Agency of Pesisir Selatan Regency, in Lengayang District, floods were recorded 5 times throughout 2020, 8 times in 2021, and 10 times in 2022. Meanwhile, in 2024, there was also a flash flood on March 7 which was caused by very high rainfall intensity and on a long time scale. This study aims to determine the flood discharge of the Batang Lengayang river with a return period of 50 and 100 years. Furthermore, this study also aims to model the Batang Lengayang river flood using HEC RAS. And to determine the area of ​​flood inundation of the Batang Lengayang river for a return period of 50 and 100 years. The results of the study showed that the 50-year return period produced a maximum flood discharge of 399 m³/second and the 100-year return period produced a maximum flood discharge of 444.46 m³/second. The modeling results showed that the flood area increased with the addition of the return period. The flood area obtained was 376 ha or 3.7 km² for the 50-year return period and 412 ha or 4.12 km² for the 100-year return period.

Abstract

Construction project management aims to manage time, cost, and resources effectively and efficiently so that the project can be completed according to plan. However, in practice, many construction projects, especially in the Medan City area, experience significant delays and cost overruns. This is due to inaccurate cost and time estimates, as well as lack of attention to various internal factors. This study aims to analyze project cost estimation as an effort to improve construction project time performance. Data were collected from 201 respondents working in the construction sector with varying educational backgrounds and work experiences. The analysis was conducted using the covariance-based Structural Equation Modeling (CB-SEM) approach with the help of AMOS software, as well as the Maximum Likelihood Estimation technique to estimate project duration. The results of the study indicate that project cost estimation is significantly influenced by three main factors, namely Budgeted Cost of Work Schedule (BCWS), Actual Cost of Work Performed (ACWP), and Budgeted Cost of Work Performed (BCWP). Meanwhile, the time performance factor does not have a significant effect on cost estimation. On the other hand, project time performance is influenced by the availability of labor, main equipment, funding, and implementation methods. The feasibility test of the model using Goodness of Fit indicators such as CMIN, RMSEA, TLI, NFI, and CFI shows that the model used meets the Absolute Fit Model criteria, so it can be concluded that the relationship between variables in this research model is valid and can be used to support decision making in construction project management.

Abstract

The 2022 Pasaman earthquake caused significant infrastructure damage, including widespread housing losses. To mitigate future risks, constructing earthquake-resistant homes is crucial. While previous studies by Hariyanto in 2020 examined public awareness of such structures, they did not analyze behavioral changes after major disasters. This study addresses that gap by assessing how the earthquake influenced attitudes and construction practices in Nagari Kajai and Nagari Malampah. Using a quantitative approach, data were collected via a structured questionnaire, adapted from the 2021 BSPS Home Building Construction Guidebook. The survey covered five aspects: building materials, main structure, structural connections, construction quality, and post-earthquake behavioral changes. Accidental sampling was used, with 60 respondents from the two affected areas. Findings show that 60% of respondents have fair knowledge of earthquake-resistant housing, while 20% demonstrate good knowledge and 20% have poor knowledge. Pearson Correlation analysis indicates a weak but significant relationship between knowledge levels and gender (p = 0.002) and age (p = 0.034), while education and occupation showed no significant correlation (p = 0.168 and p = 0.141). Post-earthquake, a shift toward semi-permanent housing structures was observed, highlighting the need for standardized, affordable building regulations. Policymakers should collaborate with local builders to ensure effective knowledge transfer on earthquake-resistant construction. Future reconstruction efforts should integrate post-earthquake evaluations to assess long-term housing resilience.

Abstract

Bridges are critical components of transportation infrastructure, ensuring smooth traffic flow and regional connectivity. However, their structural conditions are influenced by various factors, including traffic loads, material durability, and natural disasters such as earthquakes and floods. Despite existing bridge maintenance frameworks, a comprehensive condition assessment specifically tailored to the Padang-Bukittinggi route has not been thoroughly conducted. This study introduces a systematic evaluation using the Bridge Condition Rate (BCR) method to provide data-driven maintenance recommendations. A total of eight bridges along the Padang-Bukittinggi route were assessed through detailed and routine inspections, followed by cross-case analysis. The results indicate that 75% of the bridges (6 out of 8) require periodic maintenance (BCR=2), 12.5% (1 bridge) necessitates rehabilitation (BCR=3), and another 12.5% (1 bridge) demands immediate replacement (BCR=5) due to severe structural damage. These findings highlight the urgency of targeted maintenance strategies to enhance bridge longevity and operational safety. The study provides critical insights for policymakers and infrastructure authorities, emphasizing the need for proactive maintenance planning to ensure road network sustainability and public safety.

Abstract

Plastic waste, especially Polyethylene Terephthalate (PET), is one of the biggest environmental issues in Kediri City, with a volume of 140 tons per month. This research aims to utilize PET plastic waste as an additional material in the Asphalt Concrete-Binder Course (AC-BC) mixture. The study was conducted using an experimental method with variations in PET levels of 0%, 6%, 8%, and 14% of the total weight of the mixture. The test was carried out using Marshall standards to evaluate performance parameters such as stability, flow, VIM (Void in Mix), VMA (Void in Mineral Aggregate), and VFB (Void Filled with Bitumen). The results showed that the addition of PET to 6% increased the stability of the mixture to 6300 kg, higher than the mixture without PET (6200 kg). The flow value increased with the addition of PET, reaching 3.8 mm at a rate of 14%. In addition, VMA and VIM tend to decrease, indicating an increase in the density of the mixture, while VFB achieves an optimal value at a PET level of 6%. This study concluded that PET waste can be used effectively to improve the performance of AC-BC mixtures, with an optimal level of 6%. The utilization of PET plastic waste not only improves the performance of road infrastructure but also contributes to the reduction of plastic waste, thus supporting environmentally friendly and sustainable construction solutions.

Abstract

Inhibiting Factors of the Acceleration of Irrigation Water Use Improvement Program (P3-TGAI) is a program for rehabilitation, improvement, or construction of irrigation networks based on the participation of farming communities which is carried out in a self-managed or non-contractual manner follow-up to the Ministry of PUPR Directorate General of Water Resources. Based on the evaluation results from Pambudi & Pramujo in 2023, the implementation of P3-TGAI activities at the basic level still encounters various problems, although in general many successes have been achieved. These problems are seen from the aspects of funding transparency, institutional readiness in the field, late determination of target locations, and less than optimal socialization at the farm level. These problems will hamper the aims, objectives, and goals of P3-TGAI activities. In order for the future implementation of this activity to run smoothly, research was conducted to find out what are the inhibiting factors that have the potential to hinder the success of this inhibiting activity in the preparation stage, planning stage, and implementation stage. The research was conducted using a quantitative descriptive method with a questionnaire instrument. The questionnaire was distributed to assistants. From the results of the study, it was found that there were 15 inhibiting factors with a very high influence on the implementation of P3-TGAI activities. 60% of them came from the preparation stage, 27% came from the implementation stage, and the rest (13.3%) came from the planning stage. Of all the inhibiting factors with a very high influence, there is one inhibiting factor with the highest score, namely communication with the community is not good. The solution to poor communication with the community is that the assistants build good emotional relationships with the community, ТPM must often go to the field, and assistants mingle with the community. In terms of general project objectives, inhibiting factors that hinder timeliness are lack of community participation and poor communication and coordination by the community. The inhibiting factors that hinder quality accuracy are the lack of knowledge and experience of the assistants and the lack of socialization to the village community. And the inhibiting factor that hinders cost accuracy is that the community is manipulated by other parties.

Abstract

The objective of this study is to evaluate the horizontal distribution of particulate matter concentrations (PM10 and PM2.5) in ambient air within the vicinity of the cement factory, with consideration for variations in spatial and temporal. The measurements were conducted using the EPAM 5000 instrument, with a total of six sampling points at distances of 0 km, 0.5 km, 1 km, 1.5 km, 2 km and 2.5 km, both during the day and at night, over a period of three days. Meteorological parameters such as air temperature, relative humidity, air pressure, and wind speed were measured to analyses their influence on particulate matter distribution. The findings revealed that the highest PM10 and PM2,5 concentrations were measured at the location closest to the factory (B1) with values of 113.98 μg/m³ and 75.73 μg/m³ at night and 52.80 μg/m³ and 28.27 μg/m³ during the day. A clear pattern of decreasing concentrations of both types of particulates as the distance from the source increases is evident, with a significant decrease occurring at a distance of 0-0.5 km. The PM2.5/PM10 ratio at night (0.67) was higher than during the day (0.56), indicating a greater contribution of fine particulates at night. Meteorological conditions play an important role in the distribution of particulate matter, in particular changes in wind direction and wind speed at night contribute to differences in the concentration and distribution of particulate matter. The results of this study indicate an increased risk of exposure to particulate matter in areas near factories, especially at night, which can be a basis for consideration in the preparation of air pollution control policies and efforts to safeguard public health.
