When carrying out activities, companies need human resources to achieve company goals, namely work productivity. Work productivity is a measure of input and output as well as the role of labor in the company. The factor that affect work productivity is work discipline. Discipline is an attempt to comply with the applicable regulations in the company. Employees must pay attention to the part of work discipline, especially employee absenteeism. Because work discipline greatly affects employee productivity factors. That’s why this research was conducted to determine the effect of work discipline on work productivity with case study in PT.

One of the methods used by the Indonesian government to control the development of the country's economy is by reallocating and refocusing the budget. One of the impacts on the implementation of construction services is that it can cause delays in project completion. Anticipating delays is by accelerating by taking into account the factors of time, cost, and quality, in order to obtain optimum cost, effective time, and standardized quality. The research method used in analyzing delays is by using the critical path method (CPM), where work that is affected by the critical path can be accelerated. Of the several work items that are being accelerated, by analyzing several alternative accelerations from several items and determining the most optimum value of the several options.

The conclusion from this study was that the mixture variations were in accordance with quality III on SNI 03-2095-1998, namely on the replacement of part of the clay with 15% bagasse ash and 15% coal fly ash with a specific gravity value of 1.558 gr/cm3, 15.169% porosity, flexural strength of 91.53 kgf, and a thermal conductivity of 0.114 W/m.K.","PeriodicalId":416376,"journal":{"name":"Indonesian Journal Of Civil Engineering Education","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126266852","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}
