Successful construction projects are projects that have effective time, economical costs, and achieve good quality. In the implementation of construction projects, construction failures are often encountered, which are caused by the implementation of construction that is not in accordance with the specifications, therefore, research needs to be done to identify factors that cause low quality performance that is very influential on construction projects. The purpose of this study is to identify the factors that cause the lowest quality performance that is the most dominant. The method in this study is to use descriptive statistical methods. Based on the results of questionnaires and data processing analysis, there are five factors that cause low quality performance that are very influential on construction projects, namely changes in the scope of work, poor material quality, design errors, poor equipment quality, and lack of workforce expertise.","PeriodicalId":31880,"journal":{"name":"Media Komunikasi Teknik Sipil","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-02-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67038574","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}

The use of polypropylene fibers could prevent structure explosion by forming canals due to melted fibers during fire, thus release its thermal stress. This study aims to determine the effect of polypropylene fibers on compressive strength of high-strength concrete after combustion at 400ºC for five hours. High-strength concrete was made by w/c-ratio 0.3 with cement amount 550 kg/m3 and added with silica fume 8% and superplasticizer 4% by cement weight. The variations of polypropylene fibers were 0%, 0.2% and 0.4% of concrete volume. The compression test was carried out on standard cylinders Ø15/30 cm of combustion and without combustion specimens at 7 and 28 days. The results showed that compressive strength of high-strength concretes without using polypropylene fibers decreased in post-combustion compared with specimens without combustion, i.e., 0.81% at 7 days and 23.42% at 28 days. Conversely, the use of polypropylene fibers can increase post-combustion compressive strength with a maximum value resulted in adding 0.2% which are 25.52% and 10.44% at 7 and 28 days respectively. It can be concluded that the use of polypropylene fibers is effective to prevent reduction of high-strength concrete compressive strength that are burned at high temperatures.","PeriodicalId":31880,"journal":{"name":"Media Komunikasi Teknik Sipil","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67039030","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}

Infrastructure projects have been the priorities in the past five years consistent with RPJMN (National Medium Term Development Plan).

However, it isn’t followed by efficiency of the construction industry. Increased cost, implementation, delay, conflict and dispute are some problems which arise from fragmentation and causes the construction industry to be known as an inefficient industry. A possible approach to solve fragment problem is studying the supply chain of the construction industry.

The objective of this study is to analyse the affect of land use changes in the Jatigede Reservoir watershed to the inflow and sediment to the reservoir. SCS Curve Number method and HEC-HMS modeling system are used to discharge analysis. Flood discharges in the reach of Cimanuk River close to the reservoir using data of 2009 are Q2=1,751.5 m3/sec, Q5=2,280 m3/sec, Q25=3,064.5 m3/sec, Q50=3,589 m3/sec. Flood discharges in the reach of Cimanuk River close to the reservoir using data of 2018 are Q2=2,053.8 m3/sec, Q5= 2,616.7 m3/sec, Q25 = 3,439.2 m3/sec, Q50=3,984.9 m3/sec. Discharges increase in 10 years (based on 2009 data and 2018 data). For example discharge increment for Q25 is 375 m3/sec. The increment is due to the increment of CN number as the consequences of land use changes. In other words along with the time, flood discharge in the rainy season increases, however discharge in the drought season decreases.","PeriodicalId":31880,"journal":{"name":"Media Komunikasi Teknik Sipil","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67039038","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 describe the conditions and evaluate the existing parking management in the case study area and design an effective parking space scenario. The object of this research is the on-street parking area on shopping area, Pemuda Street, Chinatown, Magelang. To obtain an overview of parking management in case study area, several surveys were conducted, including a parking inventory survey, occupancy survey, and parking duration survey. Secondary data collected by interview with the Local Transportation Department and the Local Public Works and Spatial Planning Department. The survey results show that existing parking requirements cannot be met by the existing parking area. However, the traffic conditions around the Chinatown have not shown congestion during peak hour. To further improve the effectiveness of parking management in Chinatown, parallel parking, parking meter implementation, the addition of parking space and the application of parking based on duration can be applied. For further research, research on parking using special transportation software can be done.","PeriodicalId":31880,"journal":{"name":"Media Komunikasi Teknik Sipil","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67039013","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}
