Identification and Mitigation of Waste Construction Project Material (Case Study of Building Projects in Badung Regency)

Abstract

Construction projects contribute to the damage to nature, among others, from material extraction, material processing, material distribution, construction processes, land acquisition for buildings and energy consumption in building operations. Besides that, construction activities also produce high enough waste. One of the discussions to overcome the problem of global warming and construction waste is to promote sustainable construction or what is often referred to as sustainable construction. In the green construction concept, one of the things that needs to be considered is waste management. The purpose of this study is to determine construction activities that have the potential to cause the construction material residuals that arise in construction projects and analyze mitigation actions to minimize the occurrence of material waste. The methods used for data collection are field observations, interviews and questionnaires. Data analysis uses qualitative analysis to determine dominant activities as a cause of waste material and mitigation actions that can be done. The results of the study stated that the activity as a potential factor causing potential waste material in building construction projects in Badung regency which most often occurred was "lack of skilled labor" with a mean value of 4.22 while the activity as the causative factor that had the greatest impact on influence was "quality material does not match specifications "with a mean value of 1.51. From the waste risk matrix, it is found that "lack of skilled labor" is included in the category of very high waste risk due to the frequency that often occurs so that it is a very serious disruption to project implementation and corporate finance.
