Research on the hydroponics system with axis has been done. Data was analyzed using completely randomized design, with 5 treatments and 3 replicates. For testing the concentration of ammonia and phosphate dilution of the sample solution by using double distilled water, while to test the concentration of sulfide, zinc and iron samples treated early with wet destruction process using HNO3 65%. For ammonia and phosphate levels in the analysis using UV/Vis whereas content analysis sulfide, zinc and ferrous metals using atomic absorption spectrophotometry (AAS). It was obtained optimum time for the absorption of planting media at 30 days with the hydroponics system. At this optimum time to do the hydroponics system with a variety of media using lettuce plants (Lactuca sativa L.), as a plant that will help reduce the levels of ammonia, phosphate, sulfide, zinc, and iron. Ammonia analysis showed a good combination of planting medium on charchoal rice husk (CRH): coconut fiber (CF) (50:50) with 79.14 mg/L concentration. While the analysis of phosphate and sulfide good planting medium CRH at 100% with a concentration of 74.05 mg/L and 0.86 mg/L. Analysis of Zn at 100% CF media with concentration 0.04 mg/L and Fe on a combination of CRH : CF = 1: 4 mg/L. From these data indicate that with the hydroponics system can reduce the concentration of ammonia, phosphate, sulfide, Zn, and Fe.
