Abstract

The construction of a multi-storey building requires a structural analysis that is also planned to be earthquake resistant. The building structure is planned using the calculation procedures for reinforced concrete structures based on SNI 2847:2019 and SNI 1726:2019. The evaluation of structural elements carried out will show how the difference in reinforcement detailing of reinforced concrete beam structural elements is evaluated based on SNI 2847:2019 and SNI 1726:2019, knowing the strength of the reinforcement in the beam installed by calculating the cross-sectional analysis of bending and shear. The evaluation was carried out on the upper structure of the Phase II Social Institution Building in Medan with a Special Moment Bearing Frame System (SRPMK). The evaluation was carried out with data collection methods, namely primary data and secondary data and data processing in the form of direct planning methods with the help of SAP 2000 V.24 software so as to obtain the results of the analysis which is the purpose of this research. The results showed that all beams have nominal moment strength that meets the requirements (ϕMn) > Mu , nominal shear strength on the beam meets the requirements Vu < ϕVn. The detailing of the installed reinforcement was carried out in the evaluation of flexural strength and shear strength calculated in accordance with SNI 2847:2019. The results also show that the deviation between levels meets the requirements of the deviation between floors of the design level (Δ) < (Δa) in accordance with SNI 1726:2019.

Abstract

In construction work, problems such as volume estimation, construction methods, and work interfaces often occur. Problems like this can be minimized with the Building Information Modeling (BIM) method. BIM changes conventional methods from being inefficient to integrated and collaborative processes. The various benefits and advantages of using BIM include the integration between design and construction. The application of BIM can minimize errors between design and construction. In BIM, we can define some modeling information, like coordinate, model view, clash detection, rebar schedule & detail fabrication, concrete volume, and others that are useful in the construction process. This study applies Autodesk Revit software for volume estimation and analyzes the differences in the BIM-based volume estimation results with conventional methods. The Revit software volume output is then compared to the existing or contracted Bill of Quantity (BOQ). The results of the evaluation show that the volume contains from the BIM calculation on the volume of concrete is 3056.31 m3 and the weight of the reinforcement bar is 540.18 tons, these results are different from the BOQ of the contract, each of which is 2765.11 m3 for concrete volume and 490.05 tons for reinforcement bar weight, which each has a shortage of 291.20 m3 and 52.64 tons.

Abstract

This research investigates open impeller centrifugal pump vibration analysis through a comprehensive examination of simulated predictions and empirical measurements. The study aims to assess the correlation between simulated models and experimental data, exploring the sensitivity of pump vibrations to operational parameters and elucidating the strengths and limitations of both approaches. Utilizing a validated simulation model, the research closely compares predicted vibration characteristics with empirical measurements obtained from controlled experiments. The analysis reveals a strong correlation between simulated and measured data, validating the simulation's predictive accuracy in replicating the pump's vibration behavior. Despite minor discrepancies, primarily at higher operational speeds, the overall alignment reaffirms the simulation's credibility. The study highlights the pump's sensitivity to operational parameters, emphasizing the influence of flow rates, material properties, and rotational speeds on vibration levels. This sensitivity underscores the significance of meticulous parameter optimization for mitigating vibrations and enhancing pump efficiency. While simulations excel in predictive capabilities, experiments provide validation and realism, yet both possess inherent constraints. This research underscores the implications for engineering advancements, predictive maintenance strategies, and identifies avenues for further research. Leveraging the validated simulation model offers prospects for tailored designs, proactive maintenance interventions, and enhanced operational safety in industrial settings reliant on pump systems.

Abstract

This research endeavors to assess depression levels among final semester students, employing a comprehensive approach that amalgamates quantitative scores from standardized psychological assessments with qualitative insights garnered through structured interviews. The study aims to provide a nuanced evaluation framework that captures the multifaceted nature of mental health during this critical phase of academic life. Utilizing a weighted sum model, this investigation synthesizes quantitative symptomatology scores obtained from standardized assessments, normalized to a scale of 0 to 1, with qualitative insights rated on a scale of 1 to 10. Equal weightage (0.5 each) is assigned to both dimensions to facilitate a balanced evaluation. Data from three hypothetical final semester students illustrate the implementation of this approach, yielding overall depression levels reflective of the combined quantitative and qualitative assessments. The outcomes highlight the significance of this combined assessment approach in delineating depression levels. The research emphasizes the intricate interplay between quantitative symptomatology and individual narratives, showcasing the importance of contextual nuances in mental health evaluations. These findings signal a pathway for academic institutions to develop tailored interventions, fostering supportive environments that prioritize mental well-being alongside academic success.

Abstract

The intensity of rainfall is one of the factors causing inundation in an area which is one of the drainage problems in the city of Medan which is increasingly feared in recent years, population growth in the city of Medan is increasingly rapid and the need for land that was originally green is now becoming a denser residential area and more and more road paving which causes rainwater cannot absorb into the ground. In addition to flooding factors, watershed conditions that often experience erosion make river silting which results in reduced flow carrying capacity so that the increase in discharge is greater so that overflow occurs. The purpose of this rainfall analysis is to find out what problems make puddles not fully drain water when the rain discharge is high and to find out how much cross-sectional capacity is suitable to be used in accommodating flood discharge in drainage at the research site. The research method calculates rainfall intensity by comparing the Mononobe method and Van Breen method by analyzing the plan discharge to determine the feasibility of cross-sectional capacity by analyzing the planned flood discharge, where the results of the analysis of the 2-year period of channel discharge capacity (Qs) = 262.622 m3⁄sec so that the calculation results that the value of the channel discharge capacity is smaller than the plan flood discharge value is greater, so that the capacity proves that the drainage canal is not able to accommodate the flow of water which results in flooding.
