Abstract

In structural work, especially corewall, the use of conventional formwork systems decreases work effectiveness over time. PT. Total Bangun Persada, one of the stakeholders that applies innovation to increase the effectiveness of that is by using the rail climbing system as a solution to the problems faced. This study will compare the time effectiveness of conventional systems using corewall using the rail climbing system which was analyzed using cyclone to obtain effective repeat cycles. From the two systems, the results show that the corewall work using the rail climbing system is more effective with a work duration of 78 days compared to conventional system formwork with 84 days of work duration.

Abstract

Concrete is one of the most common construction materials used for road pavement. In pavement concrete roads are required to have good flexural strength, providing sufficient comfort for drivers and durability. To answer the demands, it is necessary to conduct research and experiment, one of the ways is by using added materials (admixture). This study aims to determine the effect of the addition of fly ash, plastic dodol, mille scale and superplasticizer to the flexural strength of concrete. Concrete is planned with fc 29.05 or K-350 with fly ash as much as 10% of cement weight, plastic waste dodol waste 0.15%, 0.25% and 0.35% of sand weight, 5% mill scale of weight of sand and superplasticizer as much as 2% of the water weight. Testing sample at age 7, 14, 28 days, to know compressive strength and flexural strength by converting from result of tensile strength of concrete and absorption.

Abstract

This study aims to analyze the productivity of structural workers in the Padina Soho & Residence Project and make the Quality Management System based on ineffective work as a tool to control the productivity of structural workers' performance. Data collection techniques are carried out by field observations and interviews. The method used to measure the level of productivity is work sampling. The productivity measure obtained from this analysis is the labor utilization rate (LUR). In this study there are three types of structural work observed, formwork, reinforcement work, and casting work. Furthermore, the development of the Quality Management System is based on ineffective work as a tool to control the productivity of structural workers' performance.
