However, each construction project has different risks depending on the type of project and project environmental conditions, so it requires handling different project implementation methods.In a jetty project, risk assessment is carried out from both technical and non-technical perspectives. From a technical point of view, risks are assessed starting from soil conditions, water level, weather, installation methods, design changes, etc. Meanwhile, from a non-technical perspective, the risks arising from the environment, social and social aspects are assessed. economic, legal, and institutional aspects as well as finance and investment.This summary literature review shows that Technical Risk has the greatest impact on jetty projects in the internal and external project category.","PeriodicalId":31886,"journal":{"name":"Rekayasa Sipil","volume":"21 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74911324","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}

Penerapan manajemen sumber daya manusia secara sistematis dapat meningkatkan produktivitas sebesar 3.27% dari total produksi (Katou, A.A., & Budhwar, P., 2015). Sehingga, manajemen sumber daya manusia merupakan aspek yang sangat penting dalam banyak sector (Eze, M.O., 2018). PT.

The issues are usage of non-shrinkage concrete infill cast inside hollow of pile and ductility. An experimental test was carried out to investigate the effect of two different concrete infill types which were common concrete fc’ 35 MPa and non-shrinkage concrete fc’ 54 MPa. A finite element model was validated against experimental test. The results were compared in terms of hysteresis curve, ductility, and performance level. Ductility is one of the important parameters to describe performance of spun pile connections under seismic load. There are different approaches to calculate ductility and this leads to four different ductility values. Hence, ductility of spun pile with concrete infill is in the range of 3.2 to 4.8. Behavior of spun pile with non-shrinkage concrete infill is slightly improved although the results were almost similar.","PeriodicalId":31886,"journal":{"name":"Rekayasa Sipil","volume":"55 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86485530","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 reservoir life is analyzed based on how long the dead storage has been filled with sediment.

However, it has been well known that housing projects are prone facing various quality problems that bring adverse consequences for project performances, i.e., cost, schedule, productivity, and satisfaction of housing customers. The objective of this study is to investigate further relationship of quality performance against labor productivity, rework, and customer satisfaction. The hypothetical model was analyzed by using Structural Equation Model approach based on collected data through survey questionnaires of 45 respondents derived from site personnel of PT. Bumi Parama Wisesa which consist of several working divisions. The final model consists of 20 indicators in total reflecting all tested variables. From the results of the data analysis using PLS-SEM, it was revealed that quality performance has a strong relationship among the tested variables. Especially on customer satisfaction and rework variables. Customer satisfaction and rework have path coefficient value (β)0.325 and -0.558 respectively. With this result, it can be concluded that better-quality performance will improve customer satisfaction and rework reduction. The findings of this study provided important contribution for construction practitioners especially those who involved in the development of housing project to pay more attention in the implementation of quality management by developing effective and efficient project quality program. thus, labor productivity, reduction of rework and customer satisfaction can be significantly improved. Considering, housing projects vulnerable facing quality failure due to low-quality management on site were performed by mostly housing contractors in Indonesia.","PeriodicalId":31886,"journal":{"name":"Rekayasa Sipil","volume":"40 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90515602","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}
