Analysis of Construction Wastes: Case Study of Commercial Housing Projects in Bandar Lampung City

Abstract

Construction waste is a significant environmental issue, particularly in rapidly developing urban areas of Indonesia. In Bandar Lampung City, total solid waste reaches 850 tons annually that cause environmental damage and soil pollution. This study analyzes the types of construction waste, their causes, and handling methods in commercial housing projects. The data collected through structured interviews and field observations, then analyzed using descriptive statistical methods. Results show that the most frequently generated wastes are cement packaging, wasted cement, wasted sand, brick fragments, and ceramic tile scraps. The dominant causes include inefficient unloading methods (25%) and unused cutting waste (25%), followed by excessive waste from application processes (19%) and weather effects (13%). Common handling methods identified are burning, reselling, reusing, and burying waste materials. The findings provide recommendations for improving construction waste management practices to support environmentally friendly housing development in Indonesia.
