Abstract

The development of the construction industry shows increasingly stringent and complex challenges. The high number of work accidents in Indonesia is caused by several reasons, one of which is the lack of workers' awareness of the dangers contained in project work. This gives a signal that young people have the potential to lack awareness of safe behavior. This study aims to determine whether young workers are one of the causes of work accidents in the construction environment, the level of workers' awareness of hazards, and the dominant factors that affect the level of workers' awareness of hazards in the construction environment. Factors that affect the level of worker concern about hazards in the construction environment include the availability of complete PPE, strict sanctions against workers who violate SHE regulations, and the availability of a special unit that manages SHE. The method to analyze the data was one-sample t-test. From the research result, young workers still become one of the factors of work accidents, and the level of awareness of young workers towards hazards in the construction environment is still minimal or low. The dominant factor that affects the level of concern for workers to hazards in the construction environment is the availability of a special unit that manages SHE. Keywords: Work accident, Young worker, Level of awareness of worker.

Abstract

The placement of dilation in the building structure with horizontal irregularity causes a different response to the structure during an earthquake, because the structure is divided into several individual structures that stand alone so that they are different from the original structure. The proper placement of the dilation in a building will reduce the risk of collapse of the building during an earthquake as well potentially making structures simpler and more efficient. This study uses the design analysis method to compare the earthquake shear force, structural response, and internal forces in the structure due to the placement of the X-direction and Y-direction Dilatation. greater than the X direction dilatation, which is 42% in the X direction and 38% in the Y direction. The deviation that occurs in the Y direction dilation is greater than the X direction dilatation. X, but the internal force due to the Y direction of dilation on the beam is greater than the X direction dilation placement. So that the use of the Y direction dilation is slightly better than the use of the X direction dilatation in several things, such as the earthquake force and the inner force on the smaller column.

Abstract

An important step toward preventing work accidents on construction projects is the implementation of Sistem Manajemen Keselamatan Konstruksi (SMKK). According to Peraturan Menteri PUPR No. 10 Tahun 2021, The X Highway is a project with a high safety risk rating. This study examines how SMKK elements are applied and how that application influences risk management during bridge upper structural work. Examining documents, conducting interviews, and distributing questionnaires are all examples of data collection techniques. The first analysis involved determining whether each document was appropriate for each element before dividing the number of indicators attained by the total number of indicators. The SPSS application was used to carry out statistical computations for the second analysis. According to the findings, the X highway Project has an average value of 92% of the SMKK implementation rate, indicating a satisfactory application rate.From the results of hypothesis tests on the application of SMKK elements to risk control, of the five SMKK element variables, three SMKK elements partially have a significant effect, and simultaneously, the SMKK element variables have a significant effect. The results of the projection of the multiple linear regression equation on the value of the level of application of the SMKK element show that the Perencanaan Keselamatan Konstruksi and Operasi Keselamatan Konstruksi elements have a low value of risk control influence compared to other SMKK elements. So, it has a higher possibility that these elements will be a source of risk to the upper structure work of the X Highway Project. Keywords: Risk of Control, SMKK, Upperstructure of the Bridge.

Abstract

Research at the Polytechnic, including thesis work by final year students, could be integrated with the applied statistics’ competencies. This research aims to analyze the integration of applied statistics in the thesis completion of polytechnic student. Research data were collected using scientific questionnaires and structured interviews. Simple linear regression analysis is used as the analyzing method towards research questionnaire’s data. The descriptive results show that the most integrated competency of applied statistics is research’s hypothetical testing, followed by developing research instruments, presenting demographic data, collecting data, and determining the population and sample. The results of simple linear regression analysis with hypothesis testing show that the integration of applied statistics has a positive and significant impact on thesis completion of polytechnic student. These results were reinforced by structured interviews, so that it was found that the positive and significant impact felt by students lay in the better management of their thesis after integrating applied statistics. So, it can be concluded that applied statistics can be more integrated by polytechnic students to improve the management and quality of thesis research.

Abstract

A problem that often occurs in construction projects is the delay in the implementation process. Various factors cause the delay, but in developing countries such as Indonesia, the dominant delay occurs because the implementing contractor causes it for unforgivable reasons (non-excusable delay). This study aims to determine the influence of the non-excusable delay parameter and the relationship between these factors. The research is quantitative with data collection techniques in the form of unstructured interviews, field observations, and surveys using research questionnaires with the number of respondents obtained as many as 33 people consisting of the owner, construction management consultant, quantity surveyor consultant, and ends with confirmation of the results. Research on the implementing contractor. Data analysis was performed using multiple linear regression analysis. The test results of multiple linear regression analysis show that the non-excusable delay factor can significantly affect the completion of construction projects. The influence of each element is 0.434 units for the lack of contractor competence, 0.067 units for inappropriate implementation planning, and -0.097 for inefficient field management units. And simultaneously, these three factors can significantly increase the project delay value index.

Abstract

Earthquakes are a serious threat in the construction of multi-storey buildings in Indonesia, which are divided into several seismic design categories. The design of seismic-resistant buildings requires the management of plastic hinges to reduce seismic loads. The aspects of seismic-resistant structural design in Indonesia are regulated by SNI 1726:2019, SNI 1727:2020, and SNI 2847:2019. Intermediate Moment Resisting Frame System (IMRFS) and Special Moment Resisting Frame System (SMRFS) are used based on seismic category and earthquake intensity. Pushover analysis is used to analyze the structures behavior when exposed to seismic loads. This research designs seismic resistant structures with IMRFS and SMRFS at different locations with the aim of assessing structural performance and gaining reinforcement to the concrete ratio, which is relevant for the design and construction of multi-storey buildings in Indonesia. The results of this research are the structural performance levels, reinforcement volume, concrete volume, and the reinforcement to concrete volume ratio. Both IMRFS and SMRFS reached Immediate Occupancy to Life Safe performance levels after the earthquake because their monitored displacement was not significantly different. The structural failure modes of both systems meet the Strong Column–Weak Beam requirements. The distribution of plastic hinges also remains in the Immediate Occupancy category.

Abstract

This study aims to determine the performance of concrete using the residual of steelmaking materials (Precious Slag Ball) as a partial substitution of fine aggregate. In this study, the test object was made with a water–cement ratio of 0.3 and using Precious Slag Ball’s proportions of 0%, 15%, 30% and 45% to the weight of fine aggregate. The test object was then immersed in sea water obtained from the estuary area. The fresh concrete test consists of slump test, initial setting time, and unit weight of fresh concrete. The hardened concrete test consists of unit weight of hardened concrete, compressive strength, and splitting tensile strength. In the 45% Precious Slag Ball variation, the use of Precious Slag Ball in concrete increases the maximum slump workability up to 32.25% and the unit weight value of fresh concrete up to 5.98%. In the setting time test, the fastest setting time is 261 minutes from the 15% Precious Slag Ball variation. In the hardened concrete test, the use of Precious Slag Ball increased the unit weight value of hardened concrete up to 4.94% at a variation of 45% Precious Slag Ball. The greatest value of concrete compressive strength test using 30% of the Precious Slag Ball as a substitution of fine aggregate variation found at the age of 3, 7, 14 and 28 days. The use of Precious Slag Ball is proven able to increase the compressive strength and tensile strength as the concrete tensile strength increases up to 7.12% at a variation of 30% Precious Slag Ball.

Abstract

Earthquake-resistant building design is very important, especially in earthquake-prone areas such as Indonesia. The shape of the column cross-section and the ties' configuration greatly affect the building's stiffness when exposed to earthquake loads. Therefore, knowing the optimal tie configuration to increase earthquake resistance is important. This study aims to analyze the structural performance of a 10-story building using columns with spiral stirrups and square stirrups. Model 1 uses columns with square stirrups, Model 2 uses spiral stirrups, and Model 3 is a combination of both. Simulations were conducted using ETABS 18 software, where the base shear force, displacement, and inter-story drift as well as the collapse pattern and performance level of the structure were analyzed using the pushover analysis method to determine the effect of each configuration on the stiffness and ductility of the columns when receiving earthquake loads. Analysis of Variance (ANOVA) analysis was carried out to ensure that the differences in seismic performance between the three models were significantly validated. The results show that Model 2 has lower displacement and base shear force values and smaller inter-story drift than the other models, and the collapse pattern and structural performance level of Model 2 are also smaller than the other models. The ANOVA results showed no significant difference between the models. This is because the differences in displacement and drift values are relatively small. These findings can provide guidance for selecting the most efficient column tie configuration for resisting earthquake loads and achieving safety levels.
