N2 - The objective of this study was to know the maximum cadmium (Cd (II)) removal efficiency and the optimum contact time in leachate from landfill using immobilized Skeletonema sp. Skeletonema sp. was immobilized by sodium alginate 0.65%. This study used 1, 2, 3, 4, 5, 6, and 7 days of contact time. The data were analyzed by statistical analysis through Anova One-Way (α = 0.05) method, then continued with the Duncan test (α = 0.05). The removal efficiency of Cd(II) was increased by increasing contact time. The highest removal efficiency of Cd(II) in leachate from landfill by immobilized Skeletonema sp. was at seven days of contact time with the 95.70% removal efficiency. The removal efficiency at 1, 2, 3, 4, 5, 6, and 7 days respectively was 45.88%; 47.25%; 64.18%; 77.23%; 92.53%; 93.81%; 95.70%. The highest result of removal efficiency of Cd (II) in landfill leachate was 95.70%. The optimum contact time was six days.
