- ABSTRACT This study aims to improve the quality of wastewater effluent chemical industry by using artificial wetlands vertical subsurface flow (VSSF Wetland) and horizontal (HSSF Wetland). Wastewater parameters chosen are nitrite and ammonia that still exceed water quality standards. The study was conducted by using two reactors of the same size, with the planting medium sand, gravel, and wastewater effluent to surface boundary which included planting medium. Plants used are plant based Mendong because previous studies, using the same method, this plant can improve the quality of wastewater effluent paper industries. Research carried out for fourteen days in which every two days once the sample quality testing. Based on the research results, both methods of artificial wetlands subsurface flow vertically or horizontally to reduce the concentration of nitrite and ammonia from wastewater effluent chemical industry significantly. Wetland VSSF method can reduce nitrite from 0.31 mg / l to 0.14 mg / l and ammonia from 2.403 mg / l to 0.683 mg / l. While the method can reduce nitrite HSSF Wetland of 0.31 mg / l to 0.08 mg / l and ammonia from 2.403 mg / l to 0.963 mg / l. Conclusion of this study is wastewater effluent treatment using Vertical Sub-Surface Flow Wetland and Horizontal Sub-Surface Flow Wetland can reduce levels of nitrite and ammonia. Method of Vertical Flow Wetland Sub Surface can reduce nitrite to ammonia efficiency of 56% and 72%. While the method Horizontal Sub Surface Flow Wetland to reduce nitrite with an efficiency of 76% and 60%. Keyword : Wetland, Nitrit, Amonia.
