Airports and highways stand as crucial economic assets in contemporary society, serving as vital indicators and contributors to public comfort and well-being. The quality of a nation's roadways reflects its progress and development, necessitating thorough assessments and maintenance strategies to counteract deterioration over time. In civil engineering, the selection between flexible and rigid pavements holds significant implications for infrastructure longevity and cost-effectiveness. The Pavement Condition Index (PCI) serves as a pivotal tool in evaluating pavement conditions and guiding maintenance decisions. However, discrepancies in PCI values between flexible and rigid pavements present challenges in accurately assessing and managing pavement conditions. This paper explores the factors contributing to these disparities and proposes a statistical approach to analyze the relationship between PCI values for different pavement types. Understanding these differences is crucial for optimizing pavement selection, design, and management strategies, ensuring sustainable and efficient transportation infrastructure. The project aims to correlate Pavement Condition Index (PCI) with statistical parameters for flexible and rigid pavements by using SPSS software. Objectives include comparing PCI values, identifying distress types, and assessing maintenance needs for both pavement types. The relationship was predicated on the selection of six road segments, each measuring between 200 and 250 meters in length: Al Mattar Highway (A), Al Mattar Highway (B), Ghadeer-Furat Street, Al-Jenseyh Street, Al Tarbiah Street, and Messan Street. There are several classifications of these roads (Arterials and collectors). The process of selecting these six sections was based on the gradations of PCI values (good, satisfactory, fair, poor, very poor, and serious). After analyzing all the data and using the SPSS program for statistical analysis, it was found that there is a relation between the dependent variable and the independent variables, as the relation was non-linear, and the amount of correlation between the variables was 47.7% (R2=0.477).

Bridges are essential components of transportation networks and play a crucial role in the operation of our infrastructures. As a result, inspecting, maintaining, and managing the infrastructure systems is crucial to guarantee the regular operation of bridges in a healthy condition. This research aims to perform a full-scale bridge static load test on a cable-stayed bridge. This test is performed using a set of truckloads positioned on each bridge midspans. A truckload consists of four similar truck types with roughly similar weights. The bridge deck relative displacement at some measuring points is evaluated using the total station by observing the difference in bridge responses before and after the truckloads are applied. Furthermore, the existing bridge condition can be evaluated if the displacements obtained through field testing are compared to those generated using finite elements reflecting the ideal condition. Besides, mitigation strategies can be made to prevent bridge degradation or collapse. [ABSTRACT FROM AUTHOR]

Testing the performance of a network using oversize packets, by the help of 10GB MAC core verification, is a way to evaluate the speed and reliability of the network. By sending a series of oversized packets throughout the network and measuring the throughput and latency, it is possible to identify any issues or bottlenecks that may be causing reduced performance. This type of testing can be useful in modern networks with high-speed links and low latency, as the use of Oversized Packet Testcase Module can reduce the overhead associated with transmitting smaller packets and improve performance. However, it is important to ensure that all devices on the network are configured to handle the larger packet sizes and that the network infrastructure can support the increased traffic and payload size associated with Oversized Packet Testcase Module.

Together with the expansion of civil infrastructure systems worldwide, the number of damaged buildings and other structures also increases. It would likely be more expensive and wasteful of natural resources to replace everything if an improvement or enhancement is a workable replacement. It is necessary to repair or strengthen a number of reinforced concrete buildings and structures in order to increase their carrying capacity and seismic ductility. Furthermore, structural improvements can be required to manage cracking and lessen deflection brought on by changing operating conditions. Strengthening an existing structure could be preferable than dismantling an existing building or component and replacing it with a new one if you want to restrict use, limit loads, and constantly monitor the structure. This study's goal was to determine how reinforced concrete (RC) beams strengthened with externally bonded spent catalyst-based ferrocement laminates and control beams (beams without reinforcement) responded to bending, shearing, and combined bending and shearing behavior under two-point loading conditions. Lamination studies using several catalyst residue levels, including 3%, 6%, 9%, and 12% are part of this study. figuring out the appropriate catalyst usage levels to increase the strength of ferrocement laminates. As part of an early inquiry, 12 laminates of discarded catalyst-based ferrocement measuring 500 (L) 125 (W) 20 mm (thickness) were cast and tested in the lab. Three laminates in all were used to ensure repeatability. For the main investigation, eight under-reinforced RC beams measuring 750(L) x100(W) x150mm(D) were cast, of which two were control specimens and the other six were optimized. Spent catalyst-based ferrocement laminates are joined and strengthened in tension, shear, and combined tension and shear zones using a flexible epoxy method. A universal testing machine (UTM) with a 1000 kN capacity was then used to test the beam under two-point loading conditions. As a result, the bending and shear parameters of all tested beams were investigated, including strength, yield strength, ultimate load, stiffness, and ductility. A 9% dosage gave good flexural strength compared to other dosages, according to an early investigation of ferrocement laminates manufactured from used catalysts. First cracks in the control beam appeared earlier than in the strengthened beam. The reinforced beams show an improvement in load-bearing capacity of 18% in bending, 16% in shear, and 30% in the combined impact of bending and shear when compared to the control beam. The deflection of the reinforced beams was reduced by around 20% to 40% in bending, 10% to 30% in shear, and 15% to 20% in the combined effect of bending and shear when compared to control beams. Moreover, the control beam's ductility was increased by 25% in shear, 30% in bending, and 30% in bending alone as a result of the combined effects of bending and shearing. The stronger beam is stiffer in bending by around 40%, shear by 48%, and combined bending and shear by 30%, similar to how the strengthened beam is stiffer in shear and combined bending and shear than the control beam. A spent catalyst-based ferrocement laminate is a good illustration of its capacity to enhance the flexural and shear strength of RC beam retrofit systems. No beam exhibited early brittle failure symptoms. According to the test results, the wasted catalyst-based ferrocement laminates perform better than the control beam in every manner.

The coverage of network infrastructure in the form of transmitters in Indonesia is not evenly distributed and has not yet reached remote areas. This creates difficulties in the implementation of Early Warning System (EWS) since data transmission between sensors and control center is required. A proper communication system is also needed to broadcast news to communities in the disaster prone regions. A practical solution to this is to use WiFI, which can also be utilized as a repeater to an internet access network. This study analyses the performance of the remote network that will be employed to transmit data from sensors to control centers and, finally, to the affected communities. Since WiFi uses CSMA/CA (Carrier Sense Multiple Access/Collision Avoidance), its ability to transfer data will decrease when accessed by multiple users. In this study, the process of sending data from the client to server is performed at a distance of 30 km and is carried out every second for 24 hours. Data acquisition is done when there is a decrease in work units due to an increase in the number of users. After performing this long distance data transmissions, we can conclude that there are indeed busy hours in the afternoons and 'low net usage' hours during the early mornings. [ABSTRACT FROM AUTHOR]

High-quality software tends to be expensive to develop and maintain because it is used in social infrastructures. In previous studies, a description format for requirement specifications was defined in a form that can be handled by machines, and customers were asked to describe their requirement specifications using this description format. However, a method for generating test cases from natural language documents has not been developed. We proposed a method to automatically generate test cases for system tests from requirement specifications. We applied this method to various system specifications and confirmed its usefulness. As a result, sufficient accuracy was obtained, confirming the usefulness of the proposed method. We also applied the proposed method to large-scale communication node software and clarified the specification-dependent characteristics of the proposed method. [ABSTRACT FROM AUTHOR]

Due to their distinctive features, MANETs are ideally suited to several real-time applications, such as calamity control, environmental monitoring, and military activities. To assist in actualizing the vision of Industry 4.0, MANETs may also be employed with innovative technologies including cloud computing, machine learning, and the Internet of Things, etc. Any MANET-based critical real-time applications require reliable and secure data delivery. Hence, this study explores several security approaches that advance safe transmission while enhancing MANET performance. The findings of this article indicate that while significant progress has been made in terms of security of MANETs, there are still many challenges that need to be addressed. Overall, this survey paper provides a thorough rundown of security boundaries of MANETs, highlighting both the progress made and the areas that require further attention. [ABSTRACT FROM AUTHOR]

Due to the issues of climate change and global warming, the transportation industry is gradually shifting from the usage of hydrocarbon fuels to electricity. The electric vehicles (EVs) are uses battery to store the energy with is subsequently used to convert into mechanical energy while driving the vehicle. Similarly, Micro-grids are used in distribution system that adds renewable energy sources along with the loads. The batteries placed in the EVs could be used significantly applied as energy storage units within the MG system. A good control system have to research and developed in order to satisfy the goal of fast charging of the EV batteries to avoid large queues at the charging stations. In this paper, the implementation of a MG model based vehicle to grid (V2G)-grid to vehicle (G2V) system using the level-3 fast charging of EV's is presented. A level-3 fast charging model consist of a fast DC charging technology for operating the electric vehicle. Various simulation conditions were realized and results have been observed to carry out to operate the power flow of V2G-G2V. Test results shows that regulation of the active power is achieved in the MGs by using the batteries of the EVs as dispatchable sources via the G2V-V2G operational modes. The charging infrastructure that is built should be attaining minimum harmonic distortions for injecting current into the of grid as well as while charging the EV and the controller should always give the very good dynamic results in the point of the DC-bus link voltage stability.

Due to the issues of climate change and global warming, the transportation industry is gradually shifting from the usage of hydrocarbon fuels to electricity. The Electric Vehicles are uses battery to store the energy with is subsequently used to convert into mechanical energy while driving the vehicle. Similarly, Microgrids are used in distribution system that adds renewable energy sources along with the loads. The batteries of the Electric vehicle (EVs) can be possibly used as energy storage and buffering devices inside the microgrids (MGs) or parking space of buildings. These EVs can help in managing the microgrid energy balance under two circumstances, viz. surplus generation it can store the excess energy as the Grid-To-Vehicle, G2V mode by charging of the batteries and during energy deficient in the MG it can provide energy back to the grid by working as Vehicle-To-Grid, V2G operation as discharging of the batteries. To facilitate these concepts proper development of inter-connecting infrastructure and control system arrangements have to be done. This paper provides a literature survey on various architecture for realizing the V2G-G2V strategies within a MG by studying different types of power electronics interfacing (PEI) like level-1, level-2, and level-3 acting as fast charging stations for the EVs are presented. Maintaining the power balance state and improving the reliability of the intermittent renewable energy sources (RESs) MGs using proper PEI is a critical task. [ABSTRACT FROM AUTHOR]

As the Internet of Things (IoT) becomes more widely used, the danger of information leakage, the danger of information leakage, data leakage and theft of the internet of things is continuous increasing, as the communication channel for data transfer is open to the public. A considerable portion of this data includes sensitive and personal information for the user and the company as well. Because of the openness, distributed nature, and lack of control over the entire IoT environment, the number of attack vectors for bad users is significant. End-users must trust the system for the IoT to become a viable service platform. Consequently, in critical infrastructures like smart home, smart city, smart healthcare, and smart industry, information security and privacy are the major concern in the Internet of Things. In this paper, we present an information concealment strategy using steganography to protect communication in critical IoT infrastructure. RGB photographs are employed as the information carrier. Deep layers of low-distortion image channels in the least significant bit (LSB) are used to hide the data to be used as a data marker. Both mathematically and experimentally, we evaluate our method. We display mathematically that the striker's analysis cannot expect the current information. The proposed strategy outperformed previous strategies in terms of imperceptibility and capacity, as well as resilience to steganalysis attacks like histogram analysis, as demonstrated experimentally.

Despite the significance of predicting and managing potential risks in infrastructure projects, this issue has not received the attention from the executive authorities that it merits, and there remain numerous hazards that can have a significant negative influence on project objectives. By stressing the significance of computer programs in the production of a qualitative evaluation of risks and in designing effective treatments, this research thus intends to highlight the importance of risk management in providing a fundamental approach to successful project management. Data were gathered from existing literature addressing risk management to support this objective, as well as from in-person interviews with experts in building project design and implementation. An administrative system to be used in the qualitative assessment of risks and the development of appropriate treatments for those risks was then developed in light of the specific risks associated with the construction projects, mainly based on a questionnaire seeking advice from experts. In order to take advantage of the benefits of modern technology, a computer program was then created to apply the principles of the suggested administrative systems. The results of evaluation of the computer program and administrative system revealed that this program offers both efficiency and ease of use, contributing to increasing the efficiency of project management through qualitative assessment of risks, and allowing the straightforward selection of the best options to address each identified project risk. The nature of each project's different components ultimately led to a set of conclusions and recommendations emerging that include the fact that risk management studies enable project owners and managers to respond promptly and diligently when danger arises, as well as assisting engineers in making better decisions when managing projects that might otherwise be at risk of failing to achieve their goals.

The first step in prioritising district road maintenance is to identify the key maintenance criteria based on each road's actual condition, as retaining unsuitable and insignificant criteria and deleting more significant ones leads to inaccurate and unreliable decisions. The objective of this study was to acquire an expert consensus on the key criteria for the prioritisation of district road maintenance in the Iraqi infrastructure sector. To achieve this objective, a group of 13 specialists was assembled to assess a list of 34 district road maintenance criteria using the Fuzzy Delphi approach. These criteria were thus organised into seven groups based on their relative importance. The first group included the seven criteria deemed to be the most important: "Potholes", "Cracking", "Transverse slope", "Shoving", "Depressions", "Bumps and Sags", and "Patching and Utility Cut Patching". This study's findings should thus aid decision-makers in this sector in terms of making appropriate decisions for the prioritisation of district road maintenance. [ABSTRACT FROM AUTHOR]

This article presents an application of a developed methodology for the reorganization and evaluation of transport situations after the conversion of the movement of cars through a conventional three-way intersection into their movement through a roundabout. The only correct approach to improving the organization of road traffic is the correct choice of solutions for the organization and reorganization of traffic on the existing road. The research carried out is checking the improvement of the conditions, organization and safety of the traffic and whether the capacity of the intersection of a particular intersection has increased before and after its reconstruction from a three-way to a roundabout. What is specific about the developed methodology and the specific proposal for the reconstruction of an intersection is that it complies with the accepted limitations of the existing street areas and checks whether the movement of cars from all traffic flows in the busiest hours of the day in terms of traffic is unhindered. The necessary research and studies have been conducted to successfully identify and implement the most effective methods and approaches for the overall organization of road traffic and street design and reconstruction of the transport infrastructure.

Busan is one of the most densely populated cities in South Korea. The huge pressure that this megacity puts on design in terms of urban regeneration promotes innovation. The purpose of this article is to examine urban rejuvenation through the prism of one particular feature: Busan's open-air traditional markets. South Korea's growth, assisted by a strong policy and backed by Chaebols, has left an unpleasant tangible legacy. When the time came for a review, the Korean government unveiled a new, more forceful policy aimed at boosting economic vitality while also preserving Korean culture. This time, legislators have not strayed from modernity's path and have opted for sustainable design. Busan is an ideal testing ground for this new strategy. In order to preserve the Busan community's cultural past, the strict principles of sustainable design are strictly adhered. Traditional markets are seen as significant public spaces that provide access to fresh produce while also serving as crucial social infrastructure. In Korea, like everywhere, these markets suffered substantial adjustments as a result of the COVID-19 coronavirus pandemic; however, the methodology of urban regeneration is examined in this paper from two analytical viewpoints (Malecón Boardwalk-Mexico and Saint Jeanne-d'Arc church-France) regardless of the impact of the pandemic crisis on these markets. From the bottom up, we illustrate their importance as public spaces and comment on their shifting social dynamics. [ABSTRACT FROM AUTHOR]

The railway system is essential to transportation as it transports products and passengers safely. Due to increased demand for train service, the railway track will deteriorate and fail. Frequent track inspection is necessary to ensure the safety and security of cargo and passengers and prevent losses. Traditionally, railway track inspections are carried out once every few months. It is done by a human inspector or an automated vehicle, a rare, complex operation that takes too long to find and track flaws quickly, which is far from optimal. As a result, condition-based monitoring and predictive maintenance are critical because they allow railway companies to do preventative maintenance before problems and failures occur. Many sensing methods have emerged, and sensors have become much more affordable. As a result, in recent years, sophisticated monitoring equipment has been used to keep an eye on the railway track and collect data in real time. This research aims to review the critical role of wireless sensor networks in monitoring the condition of railway facilities: what kinds of sensing devices are employed in structural monitoring, and why. We will also identify their benefits and limitations. Additionally, researchers have employed AI algorithms for rail defect identification and prognosis in recent years to help the railway sector respond quickly to failures. This study also discusses the current AI techniques in diagnosing rail problems by utilizing inspection device data to create railway degradation prediction models. These models predict flaws.

The study showed imperfections in the legally established mechanism for evaluating construction organizations that participate in auctions as general contractors. But it is with such organizations that the customer subsequently concludes an agreement (contract). The formalism of the assessment of construction organizations leads to a low quality of construction and installation work on the construction of roads, failure to meet their deadlines, possible termination of the contract and the need to find a new supplier. The author proposed to introduce such a system of assessment criteria, which allows to take into account in maximum detail all the risks associated with the quality of construction work of a particular general contractor.

The article discusses the definitions of the concepts: automation, autonomy, technical means. The definition of the concept of an autonomous technical means is given. Autonomous technical means are considered as technical means with the ability to perform certain actions without human intervention. Autonomous technical means were defined as products with various degree of endurance according to a predetermined function. The analysis of legal regulation in the field of creation, implementation, use of autonomous technical means is carried out. It is concluded that there is an urgent need to create new approaches to the legal regulation of this area. The possibilities that an autonomous technical means should have for their use as a transport safety violator have been determined. Autonomous technical means with remote control technology are subdivided by the type of communication channel (mechanical, wire, radio, ultrasonic, infrared). Autonomous technical means such as unmanned aerial vehicles, RC Sports Models & Toys and Special technical means are proposed to be considered as a potential threat to transport security. A brief overview of the allocated autonomous technical means is given, as well as a comparative analysis. The comparison was made according to such characteristics as average autonomous operation time, remoteness from the operator, remoteness from the object, availability of standard means of photo/video recording, availability of standard storage medium, feedback function, availability in the market, pricing. It is concluded that the UAV is a multipurpose vehicle that can be used both for collecting data and for influencing a transport infrastructure object (can be used to destroy (attack) any targets).

Bridges as a transportation infrastructure require good management for their service functions. Bridges are subject to deterioration and need maintenance strategies to prevent their failing services. The research was conducted in the Surakarta City. The city has a 10% annual growth in transportation modes and 129 bridges which must be periodically inspected/evaluated. This study uses the Bridge Management System (BMS) as a basis for detailed bridge inspection. The evaluation is carried out by dividing a bridge into five levels of elements hierarchy. The assessment criteria are measured cumulatively from the structure (S), volume (K), damage (R), function (F), and effect (P) values by weighting of 1 or 0. Observations and assessments are carried out at the 4 and 5 levels of elements, where the rest are carried out in a superposition of the elements hierarchically. The results of the 129 bridges in Surakarta City investigated with the following criteria: bridges with damaged components or no longer functioning (replacement of components/new bridges) of 1.55%; bridges with critical conditions (rehabilitation) of 8.53%; bridges with damage requiring immediate attention (repair) 34.11%; bridges with damage requiring future monitoring of 30.23%; bridges with minor damage of 11.63% and bridges with no damage of 13.95% respectively.

On April 10th, 2021, 3296 houses suffered light damage, 1964 houses suffered moderate damage, and 1552 houses suffered severe damage due to the earthquake that occurred in Malang, Indonesia. The iMPact on public facilities included 203 damaged schools, 16 damaged health facilities, 171 damaged places of worship, and 40 other damaged public facilities. Most of the damaged buildings were non-engineering buildings with various types of damage. In Pacitan Regency, there are many low-rise to medium-rise non-engineering buildings. In addition, Pacitan Regency has a coastline that is part of the Indonesian Ocean and is located very close to the subduction zone between the Indo-Australia plate and the Eurasian plate. The main potential sources of earthquake and tsunami events in this region are thrust systems. Seismic fragility curves play a pivotal role in the assessment of the comprehensive vulnerability of civil infrastructure to prospective seismic events, as well as in the anticipation of the consequential socioeconomic repercussions. This paper presents an analysis of the fragility of non-engineering buildings and estimates of their collapse using the finite element method. Seismic fragility analysis produces fragility curves that show the probability of structure damage under various damage conditions. [ABSTRACT FROM AUTHOR]

As a result of the acceleration of the urbanization process, the increase in megacities, population growth, the demand and need for public transport are increasing every year. This, in turn, leads to the need to improve the efficiency of public transport, adapt to today's times and conditions. This determines the importance of increasing the efficiency of using the existing transport infrastructure through proper planning and modeling of urban public transport. The article describes the methodology for determining passenger traffic on existing public transport routes (using the example of the city of Urganch). At the same time, the flow of passengers in urban public transport was carried out using modern information technologies by measuring at stops, in bus stations and inside public transport. As a result of the determination of passenger traffic on public transport, the districts of the city of Urganch that require improvement of transport infrastructure have been identified.

Food supply systems are national critical infrastructures embedded in changing and uncertain environments. Hence, testing and evaluating them in their ability to meet food supply is key to reduce vulnerability to shortages. This paper presents an optimization approach to assess the resilience of nationwide food supply systems using the N-1 contingency criteria, which investigates whether the isolation of one region from the transport network destabilizes the food supply. To this end, we build a multi-regional multi-commodity large-scale model for food flow networks. Then, we implement a constraint optimization problem to find the management of food flows along the supply chain stages that minimize shortage, costs and penalties induced by the disruption for both the isolated and connected system. Lastly, resilience is quantified with established metrics. A numerical case study illustrates the proposed method, revealing which regions are critical to maintain the stability of the national food supply. [ABSTRACT FROM AUTHOR]

For the sustainability of the function of the irrigation network to be maintained and improved, it is necessary to maintain and evaluate the condition of its physical infrastructure. This study analyzes the determination of irrigation network maintenance priorities in DI Bati, DI Kolokembar, and DI Soko/Jirak which are located in Karanganyar Regency. Funds distributed by the central government can be used optimally. The study used data on climatology, hydrology, and physical conditions of irrigation networks. In addition to the above data, questionnaire data on the selection of irrigation area priorities by the relevant respondents was also used. The analysis was carried out using the AHP (Analytical Hierarchy Process) method, namely by compiling a hierarchy, comparing pairs of priority values, and testing their consistency. The results of the analysis showed that the maximum water requirement for D.I Bati rice plants was 0.09 m3/sec, D.I Kolokembar 0.05 m3/sec, and D.I Soko/Jirak 0.06 m3/sec. The condition of damage to the physical infrastructure of irrigation networks is known in Bati as 71.92% moderate, Kolokembat at 56.79% heavy, and Soko/Jirat ak 75.86% moderate. Based on the analysis of criteria the most influential in determining the priority of network maintenance is Physical Infrastructure (46%), while the least influential is Plant Water Needs (11%). By (52%), D.I Kolokembar (33%), and D.I Soko/Jirak (15%.) [ABSTRACT FROM AUTHOR]

Modern trends in the development of railway transport in the Republic of Bulgaria are related to increasing the speed and possibility to transport increasing number of passengers and cargo. This is related to the construction of new or modernization of the existing railway infrastructure. The embedding of suitable elements in the railway contact network has a significant impact on the cost of investments. This requires the design of new products which can satisfy the technical requirements and at the same time are economically profitable, i.e. development of new products with low manufacturing costs, but with the necessary strength and reliability. In this publication, several types of cantilever structures for railway contact network are investigated using the finite element method. A comparative analysis of the theoretical results and the physical testing of the prototypes was made, that allows the verification of the computational model in the zone of plastic deformations. The research was done in the laboratory of the Department of Railway engineering of the Faculty of Transport at the Technical University of Sofia. The applied loads and assessment are in accordance with the requirements of the technical specification TS-RI 007-2006 of the National Railway Infrastructure Company [1]. [ABSTRACT FROM AUTHOR]

Aerial photography is accomplished using various types of aerial vehicles and photographic techniques. Using the cameras built into the unmanned aerial vehicle (UAV), video or photos of the busy intersections can be taken from the air. This can provide information about vehicle movements, traffic flows, the presence of congestion and other factors related to the traffic level of the intersection. This report proposes a four-stage methodology for drone imaging, the results of which can be used for traffic analysis, planning infrastructure projects, improving road safety and optimizing transport infrastructure. The company's Data From Sky software has been used with a wide range of clients in the fields of infrastructure, transport and traffic management. [ABSTRACT FROM AUTHOR]

Good management of school facilities and infrastructure will help create a conducive and healthy teaching and learning environment, can further extend the life of use, can support cost efficiency and will ultimately improve the quality of education and student achievement. From this description, problems arise which are arranged so as to be able to answer questions on the problems posed such as; 1)How is the existence of the management of educational infrastructure in public junior high schools in Abiansemal sub-district, Badung Regency?, 2) What is the response of the community (parents of students) to the existence of planning management for the procurement of public junior high school educational infrastructure in Abiansemal sub-district, Badung Regency? and 3) How is it? the relationship between the characteristics of parents of students and the management of educational infrastructure in public junior high schools in Abiansemal sub-district, Badung regency. The sample was determined using the slovin method for parents of students at State Junior High Schools in Abiansemal District who had quite a lot of infrastructure problems. The research method is descriptive qualitative analysis of public junior high school infrastructure management.by optimizing parental gender, parental education and occupation. There needs to be an increase in the existence of management of infrastructure facilities on the 14th indicator of sufficient space. The implications of parental responses in managing infrastructure are real needs and needed. [ABSTRACT FROM AUTHOR]
