Abstract

The increasing number of residents every year causes the need for transportation to also increase, this also occurs on the Sukabumi-Bogor Primary Arterial Road which is a road with a fairly high volume of traffic flow, in addition because the industrial center and tourism sector are located right on the national road, Insufficient geometric roads caused by the increasing number of vehicles is also a factor that affects the high number of traffic accidents along the Cibadak – Bogor Road. The purpose of this study was to analyze the characteristics of the accident-prone areas (blackspots) on the Jl. Surya Kencana, Pamuruyan Village, Cibadak District - Jl. Raya Ciutara, Pondok Kaso Landeuh Village, Parungkuda District. The method used in this study is the EAN (Equivalent Accident Number) method and the Cussum (Cumulative Summery) method. From the results of the weighting using the EAN method, it was identified that STA 1, STA 4, STA 5, and STA 6 were blackspots. Meanwhile, the Cussum method identified STA 1, STA 4, STA 5, STA 6, and STA 9 as blackspots. The right type of handling for accident-prone locations from the observations, among others, is making a thunder strip facility close to the zebra cross area to reduce vehicle speed and installing a safety fence on the shoulder of the road so as to minimize road crossings that directly cross the road without using zebra cross facilities.

Abstract

Management on a construction project is something that cannot be ignored, because without construction management a project will be difficult to run according to expectations in the form of cost, time, quality and the success or failure of a construction project depends on the effectiveness of resource management. One way that can be done to achieve project objectives is to increase work productivity. This study aims to determine the productivity of labor in the installation of lightweight brick walls based on facts in housing projects. Labor productivity by analyzing the LUR value and productivity rating then becomes the regression analysis data to produce the model. The data search was carried out by direct observation to the field and conducting unstructured interviews with workers in the field. The resource persons are workers as artisans and workers who are experts in the work of installing light brick walls. This productivity measurement uses the productivity rating method, where worker activities are classified into 3 things, namely Essential contributory work, Effective work, and not useful. The results of the analysis show that the productivity of light brick wall installation workers based on the fact has higher productivity than the SNI labor coefficient. To calculate the labor productivity of installing lightweight brick walls, then the model from the results of this study can be used. The results of the evaluation of the model to predict labor productivity for installing lightweight brick walls have an average accuracy of 99.34%, so the model can be declared accurate.

Abstract

Every building renovation or building reconstruction often occurs demolition of the wall. The demolition of this wall becomes construction waste therefore it is necessary to experiment with using wall waste to become a productive material. This research is an experiment in making concrete using wall waste. The wall waste used is in the form of rubble from the ruins of a red brick wall. The compression test method refers to the 1974:2011 SNI regulations on concrete. In this test, the focus is on the maximum compressive strength of concrete that can be produced in the sample. Each sample of the test object is divided into three groups, each group has three test objects. The first group is a sample of pure concrete, fine aggregate 100% concrete sand. The second group is a fine aggregate experimental concrete sample containing 25% wall waste, and the third group contains 50% wall waste. The test object is in the form of a concrete cylinder with a diameter of 150 mm and a height of 300 mm. Concrete testing is carried out at the age of 7 days, 14 days, and 28 days. The results of this study provide information that red brick wall waste can be recycled into concrete material so that it does not become construction waste. It is known that the compressive strength of concrete using additional wall waste as fine aggregate meets the requirements of structural concrete quality and can improve the quality of concrete. Furthermore, it is hoped that the wall waste can be reused as an added material to the concrete mixture in building construction activities or other construction using concrete.

Abstract

The problem of clean water supply to meet the needs of the community is the main obstacle experienced by residents of Bumi Purnawira housing. Water management is completely left to the residents starting from installation of pipes to each house, installation of water meters, calculation of the cost of water usage per cubic meter, as well as administration and maintenance of the artesian well. Some problem that arise include: frequent miscalculation of cost to be paid; monthly meter recapitulation records in the form of paper prone to damage and data lost; meter recapitulation records is only kept by the treasurer, so if the residents want to know the history of meter records and the payment, they have to see the treasurer; the meter's monthly status is vulnerable to manipulation whether done by the residents or the treasurer; There is often a discrepancy between the financial recapitulation recorded and the physical cash; and financial expenditures are sometimes not properly recorded, so that it triggers the discrepancy between the recorded amount and the physical cash. Seeing the existing reality, an idea to make an application for the management of artesian well administration has arisen. The initial step is to form two teams, namely the development team and the socialization team. The development team is responsible for developing the management system of the artesian well's administration and finance. Meanwhile, the socialization team is responsible for conducting the socialization and the application training. The result of this project is an application and socialization that can help both the administrators and the residents in managing the administration and finance of the artesian well.

Abstract

This study aims to determine the inter-floor shift due to earthquake spectrum response using nonlinear pushover analysis in a clinic building located in the Cimandiri Fault Zone as a basis for healthcare infrastructure management. This is very important because healthcare infrastructure is a place that must be available in any condition, even after an earthquake disaster. The Sukabumi area is an area located in the Cimandiri Fault Zone, so buildings in this area must be specifically designed to remain intact during disasters, especially earthquakes that often cause building damage. The research object that is the case study in this study is a 4-story clinic building that uses a reinforced concrete structure. The method used in the earthquake spectrum response analysis refers to SNI 1726:2019 and SNI 2847:2019, which have available spectral response webs, while the nonlinear pushover analysis uses the ATC-40 and FEMA-440 methods implemented in ETABS. The results of the analysis show that the inter-floor shift on the second and third floors exceeds the specified service limits, so it can be stated that the clinic building structure service in this case study requires damage control (DO). This can be seen based on the analysis results that the inter-floor shift of 201 mm in the X direction and 190 mm in the Y direction can cause moderate damage that can be repaired, so that health infrastructure service management is very necessary. Controlling recurrent damage due to earthquakes can be done with three retrofit scenarios consisting of the addition of shear walls, column coating, and steel reinforcement. The three scenarios are assessed and ranked based on the reduction of shifts, repair duration, and functional disruption. The addition of shear walls is the main recommendation without disrupting functionality, while column coating and the addition of steel reinforcement can disrupt health service operations. Retrofit scenarios can be recommended to support a sustainable health service infrastructure system in earthquake-prone areas. Earthquake spectrum response is a key factor that needs to be reviewed in building damage analysis as a basis for risk control management of health service infrastructure.

Abstract

Aim: This study aims to develop an adaptive management and maintenance model for flexible pavement in coastal areas by integrating road condition evaluation, cost analysis, and the effects of seawater immersion. The model is intended to improve maintenance efficiency, extend pavement service life, and support sustainable infrastructure management. Methodology and results: A quantitative and experimental approach was employed. Field surveys assessed pavement conditions using the Pavement Condition Index (PCI), Surface Distress Index (SDI), and International Roughness Index (IRI). Asphalt samples were tested in the laboratory under seawater immersion to evaluate strength reduction through Marshall and Indirect Tensile Strength tests. Damage data were integrated with maintenance cost analysis and traffic volume, producing a predictive model using regression and correlation analysis. Initial results indicate that seawater immersion significantly accelerates pavement deterioration and increases maintenance costs compared to normal conditions. Conclusion, significance, and impact study: he proposed model provides a comprehensive framework by considering technical, economic, and environmental factors specific to coastal infrastructure. Findings highlight the importance of condition-based maintenance strategies that are adaptive to climate change and extreme environmental risks. This study contributes to achieving sustainable infrastructure, resilient cities, and climate action for coastal environments.
