Abstract

The Pesaguan-Kendawangan road section is a strategic corridor connecting industrial areas with ports in Ketapang Regency. The intensity of mining and industrial activities has significantly increased traffic loads, requiring a comprehensive evaluation of road infrastructure conditions. This study aims to assess the condition, determine the type of treatment and cost requirements on the Pesaguan-Kendawangan road section and which is a connecting road section of the industrial area in the Ketapang area. The method used is the Road Condition Index (RCI) approach which is converted into the International Roughness Index (IRI) to assess road conditions. For road improvement/reconstruction needs, the thickness of the pavement components is determined using the 2024 Pavement Design Manual by considering the Cumulative Equivalent Standard Axle Load traffic load of 3.1 × 10⁶ ESA5. The results of the study indicate that the 65.27-kilometer section has a high reconstruction need of 22.90 percent, the IRI value ranges from 1,627 to 16,041 meters per kilometer. Based on the analysis using MDP 2024, there are 5 alternative types of construction for handling the road section, because the regional conditions have limited resources of crushed stone materials, the level of difficulty of the work and difficult access to the work location, so the type of construction for handling Asphalt Concrete Wearing Course (AC-WC) with a thickness of 50 mm and a 300 mm Soil Cement foundation layer was chosen. The conclusion is that the RCI method can be used to evaluate road conditions and the MDP 2024 method can also be used to plan road pavement designs on the Pesaguan-Kendawangan road section.

Abstract

Central Bengkulu Regency is an area where the Air Hitam River estuary, located within the regency, was experiencing several problems, such as shifting estuaries due to sedimentation and shallowing. Sediment characteristics, flow velocity, and the influence of structures around the estuary were factors in this sedimentation and shallowing.This study uses data form of sediment samples collected at 3 locations as primary data, each with 3 sampling points. The research aims to analyze sedimentation in the Air Hitam River following the planned construction of a jetty at the estuary mouth. Laboratory testing and modeling using HEC-RAS were conducted to determine sediment grain size distribution and specific gravity. Laboratory results show the sediment is classified as sand with a specific gravity indicating inorganic soil. The design flood discharge calculation using the Synthetic Unit Hydrograph Nakayasu method resulted in a peak discharge of 307.011 m³/s for a 25-year return period. HEC-RAS modeling showed that sediment deposition was not significant after the jetty construction plan at the estuary. This is influenced by the dominant sediment type being sand, which has a very low settling velocity of 0.00000002753 m/s, while the flow velocity at the same point reached 3.38 m/s.

Abstract

Agriculture is a crucial sector in Indonesia’s economic development. It provides food for the population, feed and energy resources, and serves as a primary source of livelihood for rural communities. To enhance rice production, one key government program is the development of irrigation networks. These networks play a vital role in agriculture and directly impact both the quality and quantity of rice yields. Regions with natural resources that are suitable for tidal or swamp irrigation systems are continually evaluated and developed. These areas are used for agriculture, aquaculture, and water transportation. This study analyzes water quality to determine its suitability for agricultural use as outlined in Government Regulation No. 22 of 2021. Parameters measured include field assessments of physical water quality using the U-50 HORIBA multi water quality checker. These parameters cover temperature, acidity, electrical conductivity, dissolved oxygen, and total dissolved solids. The research site is Sabuhur Village, Jorong District, Tanah Laut Regency, South Kalimantan Province. Measurements of physical and chemical water quality show that water conditions in agricultural land and nearby rivers or ponds are within acceptable ranges to support farming. This condition confirms that the surrounding aquatic environment does not pose significant constraints on plant growth and instead serves as a key factor in agricultural productivity. Thus, the water at the research site is suitable for agricultural use. However, further research is needed on soil characteristics, both physical and chemical.

Abstract

The rainy season in South Kalimantan is characterized by high intensity and unpredictable patterns, posing significant risks to the success of building construction projects. These risks include material damage, reduced labor productivity, schedule delays, and increased project costs. This study aims to identify, analyze, and formulate mitigation strategies for risks caused by rainfall in construction projects within the region. Primary data were collected through questionnaires distributed to 30 respondents consisting of contractors, construction managers, and supervisory consultants, while secondary data were obtained from literature and project documents. The analysis involved validity and reliability testing of the instruments using SPSS, followed by the Severity Index method to measure the probability and impact of risks, and the Probability Impact Matrix to determine dominant risk levels. The results indicate that 25 risks factors were valid and reliable, with Cronbach’s Alpha values exceeding 0.9. The analysis identified seven high-risk variables, namely delays in material delivery, material damage due to humidity, decreased labor productivity, postponement of concrete casting, rescheduling of project activities, delays in managerial decision-making, and unexpected additional costs. Proposed mitigation strategies include contingency planning for logistics, material protection measures, flexible work scheduling, the application of adaptive construction technologies, and strengthened managerial coordination. These findings are expected to contribute to enhancing the resilience of construction projects against extreme weather conditions and serve as a foundation for developing adaptive risk management practices in Indonesia’s construction sector.

Abstract

Hot Mix Asphalt (HMA) used in the Asphalt Concrete–Wearing Course (AC-WC) layer is susceptible to permanent deformation (rutting), particularly due to high service temperatures, aggregate characteristics, and binder properties. This study aims to evaluate the effect of binder type, namely Penetration 60/70 asphalt and Performance Grade (PG) 76 asphalt, combined with fly ash (FA) as a filler, on the volumetric and rutting performance of AC-WC mixtures. The evaluation was conducted through Marshall volumetric parameters (VIM, VMA, and VFB), Marshall stability, Index of Retained Strength (IRS), and permanent deformation parameters under various testing temperatures. The results indicate that the mixture with PG76 binder exhibits a lower Optimum Asphalt Content (OAC) of 6.5% compared to 6.6% for the Pen 60/70 mixture, indicating higher binder efficiency. Volumetric analysis shows that the addition of fly ash has a strong correlation with changes in VIM, VMA, and VFB, with correlation coefficients greater than 0.7, highlighting the significant role of FA in improving the internal structure of the asphalt mixture. In terms of mechanical performance, the PG76 + FA mixture achieves a Marshall stability of 1686.04 kg, which is higher than that of the Pen 60/70 + FA mixture at 1407.58 kg. Moisture damage resistance is significantly enhanced by the addition of fly ash, as indicated by IRS values exceeding 90% for both binder types. Rutting performance results show that the PG76 FA mixture exhibits higher dynamic stability and lower permanent deformation, particularly at elevated temperatures. Overall, the combination of fly ash as filler and PG76 binder proves to be more effective in enhancing the volumetric characteristics and rutting resistance of AC-WC mixtures, making it suitable for overlay applications under heavy traffic and tropical climate conditions.

Abstract

Earthquakes are natural disasters that occur due to sudden shifts in the earth's crust. Indonesia is prone to earthquakes because it lies at the meeting point of three major tectonic plates, namely the Indo-Australian, Eurasian, and Pacific plates. One of the areas studied is Lingga Regency, which is located on the coast of the South China Sea and has a low earthquake rate. These two conditions can cause problems if the structural resistance, quality, and impact of damage caused by seawater salt are not taken into account. The purpose of this study is to evaluate earthquake vulnerability in areas with low seismic activity, concrete quality, and damage to building structures. The methods used for evaluation were Rapid Visual Screening (RVS), Non-Destructive Testing (NDT), and visual inspection. The results showed that the final RVS score at the moderate level indicated vulnerability to earthquakes in buildings B and D. Concrete quality testing on the tie beam elements of building A and the column and tie beam elements of building K did not meet the minimum requirement of 17 MPa based on the limits of SNI 2847:2019, and through visual inspection, only buildings A and K were found to have damage to the slabs. beam and slabs. The results of this evaluation can be used as a basis for implementing pre-disaster mitigation measures on the buildings, and these steps can also serve as a reference for disaster mitigation policies at the Lingga regency level.

Abstract

The use of discrete choice models has been widely applied to support the understanding of individuals' travel behavior in selecting transportation modes. The introduction of new public transportation modes (such as Trans Campus) in educational areas is believed to increase the likelihood of individuals shifting from private vehicles to public transport. This study aims to understand travel behavior patterns by identifying factors influencing individuals' mode choice decisions and measuring the probability of shifting from private vehicles to public transport for short-distance trips. Data collection was conducted using a Revealed Preference (RP) survey with questionnaires. The questionnaires were distributed directly by surveyors and through Google Forms shared via email and social media. A binomial logit model was employed to evaluate the variables influencing mode choice in the campus area, specifically the shift from private vehicles to Trans Campus. The result indicates that gender, age, vehicle ownership status, household income, driver's license ownership, travel time, daily Mode of travel, travel time, safety, and ease of access significantly affect transportation mode choice in the university area.

Abstract

Level crossings are a persistent source of traffic congestion and vehicular emissions in many urban areas, particularly in mid-sized cities where road and rail networks intersect at grade. This study investigates the impact of level crossing operations on vehicle CO₂ emissions by analyzing traffic delays caused by train movements at nine crossings in Cirebon City, Indonesia. Using field observations, four traffic-related variables were collected: train frequency (crossings/day), average waiting time (seconds), queue length (meters), and idle vehicle count (vehicles/day). Emissions were estimated using the IPCC Tier 1 methodology, and a multiple linear regression model was developed to assess the relationship between traffic conditions and daily CO₂ emissions. The results show that train frequency and idle vehicle count are statistically significant predictors of emissions, with each additional train and idle vehicle contributing substantially to total CO₂ output. While waiting time and queue length were less significant, their influence was observed to be moderated by vehicle type and traffic density. The regression model explains 99.6% of the variance in emissions (Adjusted R² = 0.996), underscoring the strength of the identified predictors. This study highlights the need for localized emission mitigation strategies, such as optimizing train schedules, improving traffic flow near crossings, and accounting for vehicle composition in emission control policies. The methodology and findings provide a practical framework for traffic-environmental assessments in similar urban settings.

Abstract

This study investigates the retrofitting of reinforced concrete beams that have experienced flexural damage due to overloading using Carbon Fiber Reinforced Polymer (CFRP) sheets. The tested beam had previously developed flexural cracks and tensile steel yielding but had not reached complete collapse, indicating the presence of residual structural capacity and ductility. Prior to strengthening, the existing cracks were repaired using Sikadur-31 CF epoxy to restore continuity in the damaged region. Subsequently, CFRP sheets were externally bonded along the tension face to enhance flexural performance. Experimental testing was conducted using a two-point loading system to evaluate load–deflection behavior, crack propagation, stiffness, and failure mode before and after repair and strengthening. The results showed that the retrofitted beam achieved a significant improvement in structural performance. The maximum load capacity increased by approximately 20.47%, accompanied by enhanced stiffness, while the ultimate deflection remained nearly unchanged. This indicates that the beam became stronger without a significant loss of deformation capacity within the tested range. Crack patterns after strengthening remained dominated by the tension zone, confirming a flexural behavior. Failure was initiated at the CFRP segment joints rather than in the compression zone, highlighting the importance of bond and joint detailing in CFRP applications. Overall, the study demonstrates that beams with prior flexural damage and steel yielding can be effectively rehabilitated and strengthened using CFRP, provided that sufficient residual ductility remains and proper design considerations are applied to avoid brittle failure.
