Therefore, this research aimed to determine the volume of traffic on Jenderal Basuki Rachmat road, determine the average speed of turning vehicles and determine the service level on Jalan Jenderal Basuki Rachmat Road. This research used the 1997 MKJI methodology. The research results explained that the largest volume of vehicles that make U-turns was 19966 vehicles/hour with a road service level of D.

Considering the growing number of goods and services procurements, the government rules to set the procurement of goods and services electronically. This helps the government to run the state budget realization that is good in timekeeping, efficiency and accountability during procurement process. The effectiveness of electronic procurement of goods and services (e-procurement) of the government is strongly related to the government’s projects. This is presented in this study using a descriptive quantitative method on processed data output from SPSS v.23. The data was sourced from recorded government’s project in LKPP in 2019. The result shows good effectiveness level at 65,9% with supporting strong correlation value at 0,812 following consummated budget at 95,71%. Based on those statistics, this paper suggests that the run of government’s projects automatically would induce a consummated budget in which targets would be achieved and provide more benefits.

This study involved 8 simply supported RC T-beams subjected to uniformly distributed load at both-edges of slab. The investigated parameters were the effect of malposition of slab reinforcement, unequal configuration of slab reinforcement and change in bar diameter of slab reinforcement. The experimental results showed that; malposition of slab reinforcement leads to a lower load carrying capacity of the slab and consequently flexural resistance decreased and slab deflection increased. The irregularity of the reinforcing bars in concrete slab affected the load carrying capacity of T-beam. Well-arranged distribution of reinforcement improves the ductile behavior of slab and reduced value of deflections at failure. Using reinforcing steel bars with diameters higher than 8mm in the reinforcement helped the slab to withstand more loads. The use of 10mm diameter in reinforcement of the slab enhances the serviceability of T-beams.","PeriodicalId":389729,"journal":{"name":"International Journal of Civil Engineering and Infrastructure","volume":"221 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116010275","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}

Based on the results of the population census, in 2016, 2017 and 2018 the average population on the island of Java reached 148 million people. As much as 56.1% of the total population in Indonesia is concentrated on the island of Java. This has an impact on increasing mobilization and the need for transportation so that traffic accidents tend to increase. Based on secondary data from the Korlantas Polri, the number of accidents increased by 5% from 2016 to 2018. The lack of handling and repairs in traffic accident-prone locations is one of the causes of frequent traffic accidents. Therefore, greater attention is needed on locations where traffic accidents often occur in order to reduce the number of traffic accidents every year. This study aims to identify LRK on national roads in Java with a frequency of 2 events per year, analyze the characteristics of accidents using the Accident Equivalent Rate and Upper Control Limit method. Data on victims of Death (D), Serious Injury (SI), Minor Injury (MI) and Material Losses (ML) in 2016, 2017 and 2018 were obtained from the Korlantas Polri. Based on these data, the AEK value is calculated and analyzed to obtain LRK using the BKA method. The results of the analysis show that the total LRK in Java is 1301 LRK in 2016, 1278 LRK in 2017 and 1309 LRK in 2018 so that there are 1296 LRK on average per year. Analysis of traffic accident data using the AEK and BKA methods in 2016 obtained the highest AEK value found in the province of East Java with an AEK value of 277024 events; Central Java with an AEK value of 183813 events and West Java with an AEK value of 139677 events, therefore there are 3 provinces with the highest number of Accident Prone Location (LRK) in Java, namely East Java, Central Java and West Java.","PeriodicalId":389729,"journal":{"name":"International Journal of Civil Engineering and Infrastructure","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126850169","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}
