Sukabanjar Village is one of the villages striving to improve basic infrastructure quality, particularly in drainage construction and road repair. However, limited understanding among village officials and communities regarding standardized construction cost estimation methods, specifically the Unit Price Work Analysis (AHSP), has become an obstacle in preparing accurate and efficient Budget Plans (RAB). This community service program (PKM) aims to improve the understanding of village officials, village hall staff, and Sukabanjar Village community regarding AHSP-based construction cost estimation planning as the standard reference for construction work cost calculation in Indonesia. The program involved socialization and training for 20 participants, consisting of village officials (RW/RT), village hall staff, and general public, introducing the basic concepts of AHSP, RAB component elements, and simple simulations of drainage and road work cost calculations. Evaluation was conducted through pre- and post-tests. The results of the activity showed a very significant improvement in participants' understanding. The average pre-test score was 42, which then increased to 75 in the post-test, reflecting an increase of 33 points (78.6%). In conclusion, the AHSP-based cost estimation planning socialization was effective in improving the village community's understanding of construction infrastructure budget management, although continued mentoring is still needed for optimal and sustainable implementation.

Coal hauling activities are an important part of mining operation because they affect production continuity, cycle time efficiency, and operational safety. This study aims to analyze the requirements of road support equipment on the coal hauling road from Sector 4 to the new Coal Processing Plant (CPP) at PT. Asmin Bara Bronang, Central Kalimantan. Based on road geometry, traffic density, California Bearing Ratio (CBR), and Unsurfaced Road Condition Index (URCI). The research method used was applied research with a quantitative approach. Primary data ware collected through field measurements consisting of road geometri observations, traffic density observations, Dynamic Cone Penetrometer (DCP) testing to obtain CBR values, and road surface condition assessment using the URCI method. Secondary data were obtained from the company records. The results showed that the hauling road has a total length of 9.1 km with an average width of 16 m, and grade values ranging from -7.68% to 10.52%, which are still below the maximum standard of 12%. Traffic density reached 184 dump trucks/day, for coal hauling and 62 units/day for construction material transportation, indicating high traffic intensity. CBR values ranged from 7% to 100%, showing variations in subgrade bearing capacity. The URCI value ranged from 72,50 to 91.00, indicating fair to good road conditions. Based on the analysis of road conditions and maintenance area requirements, the recommended support equipment for maintaining the hauling road consists of 1 motor grader unit, 1 compactor unit, 1 bulldozer unit, and 1 water truck unit.

Slums are an urban issue that arises due to rapid population growth and the limited capacity of local governments to provide adequate housing and basic infrastructure. This leads to areas with low environmental quality, limited access, poor drainage, and high socio-economic vulnerability. A similar phenomenon occurs in Jambi City, which requires a sustainable handling strategy. This study aims to analyze the strategies implemented by the Department of Public Housing and Settlement Areas of Jambi City in addressing slums and assess their contribution to environmental quality. A descriptive qualitative approach was used to understand the policies, program implementation mechanisms, and institutional challenges. Data was collected through interviews with government officials, field observations, and analysis of planning documents. The results indicate that the strategy focuses on improving basic infrastructure, such as road construction, drainage rehabilitation, and the provision of settlement facilities. This program enhances environmental quality and accessibility but faces challenges such as budget limitations, suboptimal inter-agency coordination, and the socio-economic conditions of the community. Addressing slums requires a more comprehensive approach, including collaborative governance, increased community participation, and adaptive policies to ensure sustainable improvements.

An essential stage in road infrastructure development is land acquisition, which frequently causes project delays due to its complex legal, social, and economic challenges. This study aims to identify the factors that hinder the land acquisition process in the Manado Outer Ring Road (MORR) 3 Phase 4 Construction Project and to assess how these constraints affect the progress of construction activities. The research was conducted using a qualitative case study approach, with data collected through field observations, document reviews, and interviews. The findings indicate that delays in land acquisition are caused by discrepancies in legal status and land ownership, differing perceptions of compensation value, insufficient public socialization, and weak institutional coordination. These issues lead to disruptions in the construction schedule and potential increases in project costs. The study demonstrates that land acquisition necessitates a more cohesive strategy, facilitated by enhanced communication and community engagement, fortified land acquisition management frameworks, and precise verification of ownership data. The results indicate that there must be broader mitigation strategies to prevent similar challenges in future infrastructure projects.

This study evaluates the implementation of spot-check testing for road preservation works in Manado City, specifically on the Kairagi–Mapanget segment, the Manado City–Wori boundary, and the Liwas Terminal Access Road, to identify existing problems and assess the effectiveness of engineering-based mitigation efforts. The objective is to examine construction quality compliance with technical specifications and identify operational challenges encountered on site. The methodology encompasses the measurement of asphalt layer thickness and density via a core drill, the examination of contract documents, the analysis of laboratory test results, and the execution of field observations. The findings show that most samples meet the required standards, although several locations require corrective action. Challenges arise from weather conditions, heavy traffic, equipment limitations, and the need for adaptation to updated technical regulations. Operational mitigation strategies, staff training, the use of core drill technology, and digital documentation were found to enhance accuracy and efficiency in evaluation. The research demonstrates the value of stakeholder collaboration and capacity building in supporting quality control for road preservation works. A multidimensional approach is effective in resolving technical and operational complexities in urban road projects.

The results of the study indicate that the system is able to present road construction information in a structured, accurate, and easily accessible manner. This GIS helps improve the efficiency of the monitoring process, data management, and preparation of road construction reports at the Palembang City Public Works and Housing Agency. Thus, the application of GIS can be a supporting solution in decision-making and encourage the digitalization of road infrastructure data management.

PT Adhi Karya (Persero) Tbk is a State-Owned Enterprise (BUMN) in Indonesia that operates in the construction industry. PT. Adhi Karya (Persero) Tbk. was awarded the contract for the Yogyakarta-Bawen toll road construction project, Package 1, Section 1. Construction safety is a very important aspect in the project. The toll road construction project involves work at heights, especially on erection grider work. Erection grider work is a high-risk job, so construction safety must be guaranteed. If construction safety is not guaranteed in the work environment, workers will be more careful in working to reduce risks so that work slows down. This can reduce work productivity. However, when safety is guaranteed, workers will feel safe to work so that it can increase work productivity. This study aims to determine the effect of construction safety (X) on work productivity (Y). The data collection method was carried out by distributing questionnaires to 30 respondents of erection grider workers. Data processing used the Structural Equation Modeling–Partial Least Squares (SEM PLS) method with SmartPLS 4.0 software. The results of data processing showed that construction safety had a significant influence on work productivity with a t-statistic value of 7.329 and a p-value of 0.000.  

In engineering practice, various methods have been implemented to stabilize landslide-prone slopes, one of which is the use of bore piles. Bore piles are structures that hold back soil and make slopes more stable by reinforcing the ground inside them. However, the application of bore piles in landslide mitigation presents its own challenges, making it essential to identify and anticipate potential issues that may arise in field engineering practice. Bore piles are installed vertically, either parallel or staggered, at specific spacing and are often combined with capping beams and struts to resist soil movement and provide lateral restraint. This method is commonly applied to high-risk slopes or critical infrastructures such as roads, bridges, and buildings. Anticipation strategies in engineering practice consist of three stages: planning, implementation, and long-term maintenance, with this study focusing specifically on anticipation strategies during the implementation stage. Although bore piles serve as an effective solution to reduce landslide risk, their success depends heavily on proper planning, construction execution, and maintenance. Issues such as soil conditions, construction quality, and external factors must be addressed through a comprehensive engineering approach.

Road preservation is a type of maintenance that keeps roads in satisfactory working order by using preventive, corrective, rehabilitation, and reconstruction methods. This approach makes sure that the road stays usable for the entire time it is planned to be used. In practice, preservation projects often run into delays that can lead to important contract conditions. To avoid this, there needs to be a structured way to evaluate things through a Show Case Meeting (SCM). This study looks at how SCM was used in the 2024 Girian–Kema–Rumbia–Buyat Road Preservation Project to find out what caused the delays and how well the agreed-upon fixes worked. The method included looking at physical progress, differences between planned and actual performance, and how well the contractor did during SCM Stages I and II. The results indicate that the contractor failed to provide enough workers and move the right equipment, which led to the critical contract condition. SCM Stage I did not meet the required test-case target, but SCM Stage II did, showing that the contractor was able to meet the required performance targets and finish the work on time. These results show that SCM is an important way to control contracts and fix problems, which helps construction projects get done on time and well.

Bintan Island has abundant bauxite soil resources; however, its utilization as road construction material remains limited. The scarcity of high-quality granular material in the region necessitates the use of available local resources, particularly for pavement subgrade layers. This article aims to analyze the classification and mechanical properties of native soils in Bintan Island through a systematic literature review. The reviewed literature includes laboratory test results of bauxite soil. The findings indicate that bauxite soil exhibits low plasticity, relatively high CBR values (±35%), and is classified as CL (USCS) and A-2-4 (AASHTO). These results suggest that bauxite soil is suitable for subgrade applications, although require stabilization with binding agents. The implication of this review highlights that the utilization of local materials could support sustainable infrastructure development in island regions by reducing dependency on imported materials.  

This study examines the management of Village Funds in supporting infrastructure development in Sumurgenuk Village, Lamongan Regency. The main focus of the study is the effectiveness of Village Fund management through planning, implementation, evaluation, supervision, and accountability based on the principles of good governance. The method used is a case study with a descriptive qualitative approach. The results show that the management of Village Funds in Sumurgenuk Village has been running well and in accordance with applicable regulations. The planning process was carried out in a participatory manner, although not evenly distributed across all hamlets. The implementation of physical activities, such as road construction, irrigation, and cash-for-work programs, has had a positive impact on accessibility, agricultural productivity, and community welfare. Evaluation, supervision, and accountability are carried out in layers, although there are obstacles in the equal distribution of public information and the capacity of village officials. Overall, the management of Village Funds reflects the principles of transparency, accountability, participation, and effectiveness, but increasing the capacity of officials and community participation is still needed for sustainable development.

The construction of toll roads in Indonesia often causes land acquisition disputes, especially related to compensation for remaining land that is no longer productive. Although Article 65A paragraph (1) of Government Regulation No. 39 of 2023 provides the right for the community to demand compensation for the remaining land, practice on the ground shows a discrepancy between normative rights and the realization of compensation. This research uses a normative legal approach with legislative, conceptual, analytical, and case study methods, and refers to Dean G. Pruitt's Dispute Resolution Theory and Philipus M. Hadjon's Legal Protection Theory. The results of the study show that the non-litigation resolution mechanism (problem solving) is often ineffective due to the lack of education and facilitation from the authorities, so that people tend to take the path of litigation (contending) to fight for their rights. This condition reflects the weak legal protection for people affected by national strategic projects. Therefore, it is necessary to strengthen legal education for the community and revise Government Regulation No. 39 of 2023 to include compensation for the remaining land that has lost its use value. This revision is important to ensure substantive justice and prevent the escalation of disputes. This research contributes to the development of a more responsive and equitable land acquisition policy, as well as encourages synergy between regulations, education, and effective dispute resolution mechanisms in the context of national infrastructure development.

This study aims to analyze the influence of product quality and location on housing purchase decisions at Shafira Residence Kediri. The research problem focuses on how product quality and location can affect consumers in making purchase decisions. This study employs a quantitative method with questionnaires distributed to respondents and data analysis conducted through validity tests, reliability tests, t-tests, F-tests, and multiple linear regression using SPSS 25. The results indicate that product quality has a significant partial effect on purchase decisions. This means that the better the quality of the product offered, the higher the consumer’s interest in purchasing a house at Shafira Residence. Similarly, the location variable shows a significant partial effect on purchase decisions, where accessibility and strategic positioning serve as key factors. Simultaneously, product quality and location significantly influence purchase decisions, with an F-test value of 10.727 (significance < 0.001) and a coefficient of determination (R²) of 0.671, indicating that the two independent variables explain 67.1% of the variation in purchase decisions. The conclusion of this study is that product quality and location are important factors influencing consumer purchase decisions at Shafira Residence Kediri. Therefore, developers need to improve housing product quality, ensure timely completion of construction, and enhance road access to the location in order to attract more consumers.

The increase in traffic volume in urban areas often triggers various problems, especially at Road intersection points that have a high level of interaction between vehicles. One of the locations that experience these problems is the intersection with the island of traffic without signal on Jl. Tebu-Jl. Tabrani Ahmad, City Of Pontianak. This study aims to analyze the performance of the intersection in the existing condition and project its performance in the next five years (2030), as well as formulate alternative treatment that can improve the smoothness of traffic. The analysis method refers to Indonesian road capacity guidelines (PKJI) 2023 and modeling using software PTV VISSIM. The data collected include intersection geometry, traffic volume, and vehicle speed. Traffic volumes were obtained through CCTV recordings for three consecutive days, then processed and presented in the form of tables and graphs for easy interpretation. The results of the existing condition analysis showed that the degree of saturation (DS) reached 0.407 with an average delay of 9.539 seconds (Level of Service/LOS B) based on PKJI, while VISSIM simulation resulted in a delay of 12.54 seconds (LOS B). The five-year projection (2030) shows an increase in DS to 0.878 with a delay of 15.177 seconds (LOS C) from PKJI, and 23.35 seconds (LOS C) from VISSIM, which indicates a decrease in Junction performance as traffic grows. Two handling alternatives were analyzed, namely the construction of roundabouts and the implementation of traffic flow management. VISSIM simulation shows that the roundabout can reduce the delay to 14.31 seconds with a queue length of 20.34 m (LOS B), while the flow management produces a delay of 11.81 seconds with a queue of 13.14 m (LOS B). This result confirms that both alternatives are able to improve the performance of the intersection compared to the projected condition without handling, so that it can be a technical recommendation for urban traffic planning in Pontianak.

Rural economic development in underdeveloped areas requires a strategic approach that integrates local potential, agricultural infrastructure, and appropriate technology (AT) to foster inclusive and sustainable growth. This study aims to analyze rural economic development strategies through a literature review and thematic synthesis of relevant studies. The findings reveal that optimizing local potential, such as natural and socio-cultural village resources, can enhance community economic self-reliance. Strengthening agricultural infrastructure, especially the construction of farm roads, significantly improves distribution efficiency and farmer income. The application of appropriate technology in agriculture, small enterprises, education, and healthcare further accelerates economic and social transformation in rural areas. Nevertheless, challenges such as limited basic infrastructure, digital gaps, and low technological literacy require collaborative solutions. Therefore, development strategies based on local potential, functional infrastructure, and technological innovation are essential to building independent, productive, and competitive rural communities.

Through a participatory approach and methods such as field observation, needs analysis, and solution implementation, the students aimed to empower the community to adapt to future economic changes. Key programs included training in financial management, digital wallet creation, product and packaging design, and the use of Google Maps for business promotion. The results showed improvements in awareness, skills, and readiness of the community to manage their businesses independently and remain competitive in the digital era.

A landslide that occurred on May 24, 2024, in Pekon Datarajan, Ulubelu District, Tanggamus, Lampung, caused significant disruption to provincial road access and resulted in material losses. This study aims to assess the post-failure slope stability through field geotechnical investigation and numerical analysis using the Limit Equilibrium Method (LEM), and to propose immediate countermeasures. The slope materials consist of MH (inorganic silt) and ML (elastic silt) with high moisture content and moderate to high swelling potential. The lithology is dominated by montmorillonite clay, which has hygroscopic characteristics, making it highly vulnerable to water infiltration that reduces shear strength and increases the risk of slope failure. Stability analysis indicates a post-failure factor of safety (FoS) of 1.36 (static loading) and 1.03 (dynamic loading), which decreases to 1.07 beneath raised groundwater conditions. Recommended immediate mitigation includes surface runoff control, the construction of impermeable drainage systems, the sealing of cracks using impermeable materials, and the installation of temporary slope reinforcements such as sheet piles. The implementation of these measures increased the FoS to 1.61 (static loading) and 1.16 (dynamic loading). This study provides a technical basis for the rapid and effective mitigation of landslides in areas with similar geological and hydrological conditions.

This study aims to evaluate the toll road development policy in Mojo, Kediri, and Tulungagung sub-districts, and analyze the social, economic, and environmental impacts caused. The research method used is a qualitative approach with a case study type. The results show that toll road development has a positive impact on the local economy, especially in improving connectivity and encouraging investment in the industrial and tourism sectors. However, social impacts such as community dislocation and accessibility inequality are significant challenges. In addition, environmental impacts such as ecosystem damage and air pollution also need more attention. While this policy is effective in achieving economic objectives, post-construction toll road management and maintenance still need to be improved.

This study aims to analyze the role of village government services in the development of infrastructure in Mekarwangi Village, Cisauk District. This research uses a descriptive qualitative approach with data collection methods through interviews with ten local residents. The results of the study show that village government services have made a significant contribution to the village's physical development, particularly in improving the accessibility and quality of basic infrastructure. Before 2015, road access in the village still used simple asphalt and lacked adequate drainage systems. Since 2016, the village government has begun concrete paving of roads and construction of drainage channels. Then, in 2022, road development using paving blocks was carried out in small alleys to facilitate mobility for residents, especially those living near plantation areas. Eight out of ten respondents stated that the development was very helpful, as previously they faced difficulties due to slippery and unsafe dirt roads, especially during the rainy season. These findings indicate that appropriate and responsive village government services can drive development that directly impacts the improvement of rural community quality of life.
