【 摘 要 】

Laundry services are emerging in every corner of Bali, particularly at suburban area, from cities to villages. These services help the community to ease their burden. However, the burden for the environment is increase. The wastewater from the laundries should be controlled, which should be handled natural ways. One way of reducing the dangerous chemical from the laundry wastewater can be done by Vertical-Sub-surface Flow Constructed Wetland system, using volcanic rocks as substrate of plant grow and the plant as filters. This study aimed to investigate the effectiveness of volcanic rock and Canna plants as a filter for the laundry wastewater. The volcanic rock as substrate for the plant grows was place in layers in a drum and the laundry wastewater was flowed. The parameter of wastewater laundry, such as TDS, BOD, COD and total phosphate were measured before and after treatment. The treatment was run for 6 weeks. The result shows that this system is effective that overall can reduce the parameter measured for 53.86%.
