Abstract

In the Sei Wampu Bridge work project, Binjai Pangkalan Brandan carried out bore pile foundation installation work at the A2 foundation point with a total of 21 piles. Review of the bearing capacity of bore pile foundations using Analysis from Meyerhof (1956) and the Converse-Labarre Formula method for the calculation of pile group efficiency. The time of completion of work based on the time schedule plan is 125 calendar days. This research conducted a review using the Critical Chain Project Management (CCPM) method to obtain time efficiency, so that the project can be carried out on time. From the results of analysis and discussion, it was obtained that the largest foundation carrying capacity was the result of laboratory data using method C. Significant differences in results were obtained, especially laboratory data due to the correlation value used in each method. The result of calculating the bearing capacity of the foundation based on the method of Luciano Decourt (1987) using N-SPT data is 287,600.76 kN; Meyerhof's (1956) method using N-SPT data is 265,062.68 kN; a combination of Meyerhof's method (1976), Vesic's method (1977); the combination of the Vesic method (1977), the Coyle and Castello method (1981) and the results of foundation carrying capacity analysis using the All Pile program is 41,159.85 kN. The Critical Chain Project Management method is defined as the longest chain of interrelated events, where the linkage lies in the work or resources that are interconnected with each other, by cutting 50% of the duration of the work and replacing it as a buffer. The time comparison obtained from the calculation results using the CCPM method obtained a time efficiency of 116 days with a work time difference of 7.2% or about 9 days from the existing duration of the previous 125 days, while to compare the results of the CCPM method, calculations were carried out based on realization for 97 days, where the realization results were smaller than using the CCPM method and time schedule plan.

Abstract

Background : Chronic kidney disease (CKD) is kidney damage and / or decrease in GFR (Glomerulus Filtration Rate) less than 60mL / min / 1.73m2 for at least 3 months. Chronic kidney disease can be caused by several risk factors such as hypertension, diabetes mellitus, chronic pyelonephritis, obstructive nephropathy, and other causes. The purpose of this study was to determine the relationship between risk factors and chronic renal failure in the hemodialysis unit. Method : The research method used is a Literature Review, using secondary data. Data were collected using documentation techniques. The research journals used were 12 journals with inclusion criteria for the publication date of the last 10 years, the language used was Indonesian or English, with the research subjects of patients with a diagnosis of chronic renal failure, and full text publication. Conclusion : Hypertension and diabetes mellitus are the most dominant risk factors for chronic renal failure.
