The object x building, which has an estimated project value of IDR 42,812,329,371 in structural work. With the estimated value of the work costing a lot, it is, therefore, necessary to make efforts to streamline costs by using the value engineering method; this study aims to choose an alternative material for it. This research method uses a Pareto chart to find the highest work value. The results of this study indicate that the beam work is priced at IDR 15,088,457,899, floor plate work of IDR 12,530,471,281, column work of IDR 10,228,438,679. The results of the analysis of alternative structural calculations using semi-system formwork and full system formwork, which initially used conventional formwork, were simulated using alternative 1, namely semi-system formwork,k and by using alternative two full system formwork. The two alternatives are applied to column, beam and floor plate formwork. So, for this building, it is recommended to replace formwork because the conventional formwork used in this building incurs a large enough price, it is necessary to save on beam parts, and it is recommended to use full system formwork because the cost of beam formwork using full system formwork is IDR 134,950 per square meter. For the floor plate formwork, it is recommended to use a full floor plate formwork system because the cost per square meter is IDR 202,360. And for columns, it is recommended to use full system formwork because the cost of column formwork if using full system formwork is IDR 115,290. And from the use of all the full-system formwork for structural work, a total cost of IDR 40,312,992,291.32.","PeriodicalId":482991,"journal":{"name":"Civil and environmental science journal","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136127978","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These issues can be minimised using several options, one of which is Landsat 8 (L8). This imagery has been broadly used to measure several water quality parameters, especially Total Suspended Solids (TSS) concentrations, even in Indonesia. This paper will compare several models from previous studies and a modified model generated using data from various sites. The comparison is based on their competencies to estimate TSS concentrations. The competencies are determined by the coefficient of correlation (r), correlation of determination (R2), and residual standard error (RSE) parameters as these three parameters are strongly correlated, generally applied, and provide distinctive determinations. The best model should have the highest r and R2 values, while the RSE value should be the lowest. The results imply that TSS model 4 generated in this study provides comparable results with TSS model 1, which has been generally used in Indonesia and provided favourable results. Thus, it can be an alternative model to estimate TSS concentrations in Indonesia.","PeriodicalId":482991,"journal":{"name":"Civil and environmental science journal","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136153986","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Increasing the number of vehicles operating on the road will further increase the risk of traffic accidents because it is not balanced with discipline in driving. This study's purpose is to analyze the relationship between speed and traffic accidents that occurred in Gadjah Mada and Hayam Wuruk Road, Jember, through several variations of calculations. The independent variables used are average speed and 85th percentile speed and density, while the dependent variable used is the accident rate. The analysis used is a correlation test that determines the level of closeness of the relationship between the two variables and a regression test that helps estimate the relationship between the two variables through a regression equation model that will be selected based on conditions in the field. The results of this study indicate that lower speed is associated with a lower accident rate. Meanwhile, lower vehicle density leads to an increase in the accident rate.

This study aims to assess the operational dynamics of Tiu Kulit Reservoir across varying hydrological conditions, namely dry, normal, and wet years. The analysis is based on inflow rates and equilibrium water surface elevations. To achieve the objectives, an investigation of the reservoir's operation pattern was conducted. Inflow rates and equilibrium water surface elevations were scrutinized to discern operational behaviors under different hydrological scenarios. The findings indicate distinct operational strategies for Tiu Kulit Reservoir. During dry years, the outflow rate is restricted to 1.20 m3/s at a water surface elevation of +53.07 m. Conversely, the reservoir's operation in normal and wet years allows for a maximum outflow rate aimed at satisfying water demand, set at +57.00 m. In instances of excessive rainfall, the study highlights the potential for overflow beyond the spillway threshold. The study underscores the significance of these results for effective water management and resource allocation in the region. Understanding the reservoir's behavior under various conditions enables informed decision-making and sustainable utilization of water resources. To build upon this study, it is recommended to implement continuous monitoring systems for both inflow and outflow rates. Furthermore, the installation of rainfall monitoring stations within the catchment area would enhance data accuracy. Regular evaluations of the reservoir's operational patterns are also advised, allowing for adaptive strategies in response to evolving climate conditions. Moreover, future research endeavors should focus on augmenting water supply to meet the demands of a growing population and livestock, while optimizing agricultural practices to boost productivity.","PeriodicalId":482991,"journal":{"name":"Civil and environmental science journal","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136152250","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
