Based on the regulation of the Minister of Transportation No. 63 of 2019 on Minimum Service Standards for Transportation of People by Train, the maximum delay tolerance for urban trains is 15 minutes from the total scheduled travel time. The method used is the depiction of working charts and calculations of statistical analysis with standard deviation in SPSS application version 26. The difference in the comparison of scheduled travel times with those in the field is determined by using Microsoft Excel for Windows version 2015. The performance of Blue Line routes (the KRL) was reviewed based on travel time using the SPSS (Statistical Package for the Social Sciences) analysis tool version 26. The standard deviation results using the SPSS KA 1341 analysis tool have a higher deviation standard result of 10.82, which means that the train has a higher travel time delay than the train of PT Kereta Commuter Indonesia (KCI), which experienced an average delay of 4 minutes. The cause of the delay consists of several factors, including the queue of passengers who want to get into the train and the fact that traffic on the blue line KRL route is congested. Because it has to alternate with intercity trains, and the KRL must wait.","PeriodicalId":389729,"journal":{"name":"International Journal of Civil Engineering and Infrastructure","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121070771","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}

This was due to changes or conversion of land functions which were originally water catchment areas to settlements. The large number of buildings that stand on the body of the river makes the current section of the Buaran River unable to function optimally in accommodating flood discharges, besides that there is no public awareness in protecting the environment which can be seen from the many piles of garbage in the body of the river. The purpose of this research is to find out how big the capacity of the existing Buaran cross-section is (starting from the Bukit Kencana Residential Area to the Jakarta Cikampek Toll Road) by modeling the existing cross-section using the help of the Hec-Rass application as well as recording and mapping locations that have the potential to flood. . One of the efforts that have been made by the government in controlling floods is by normalizing the river but in practice, the normalization of the Buaran River cannot be said to be running optimally. Based on hydrological calculations, the planned Q25 flood discharge is 16,307 m3/s. By using the help of the Hec-Ras application we can find out which river profiles need to be treated so that the handling of river normalization as an alternative to flood control can run optimally","PeriodicalId":389729,"journal":{"name":"International Journal of Civil Engineering and Infrastructure","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128484162","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}

This study aims to follow up on previous research that recommends improvements to the flare stack structure based on corrosion findings that occur in the area of the riser stack around the ring connection for the guy wire. By replacing rusty material, it is also necessary to consider modifications to prevent the risk of re-corrosion. Based on current design observations in the connection ring area for guy wire, side cutting is required which can result in water being trapped. This research aims to find out whether by modifying the connection ring for guy wire, this flare structure still has structural reliability when receiving critical outer loads or not. Based on the results of the study, it shows that modifying the geometry of the connection ring guy wire still provides reliable structural performance when receiving critical outer loads. The maximum stress that occurs in the area around the pad eye is 71.2 Mpa with a maximum stress ratio of 0.434 it shows that the value is still quite far from the maximum allowable voltage ratio of 1.0. So it can be concluded by modifying the connection ring for guy wire to prevent the risk of corrosion can be done without causing a decrease in the performance of the structure in withstanding critical outer loads.","PeriodicalId":389729,"journal":{"name":"International Journal of Civil Engineering and Infrastructure","volume":"422 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115919986","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}

Cold-formed steel is a material breakthrough in construction that has advantages over hot-rolled steel. Many studies have been carried out on Cold-formedsteel subjected to various loadings to examine the behavior and capacities of the sections. This study aims to investigate the behavior and section capacity of cold-formed steel unlipped channels due to axial compression loads. This research begins with conducting a literature study, then carrying out numerical analysis using the finite element method in ABAQUS, numerical test, and calculation of section capacity based on existing research in the literature. The calculation of section capacity is carried out based on SNI 7971-2013 or AS/NZS 4600:2005. The results of the numerical analysis can be seen from the behavior and capacities of the sections of the unlipped channel, the section capacity from the numerical test will be compared with the section capacity obtained from the calculation based on SNI 7971-2013 or AS/NZS 4600.","PeriodicalId":389729,"journal":{"name":"International Journal of Civil Engineering and Infrastructure","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132069165","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}
