This study uses a randomized block design factorial consisting of 2 replications, 16 combinations so that there are 32 plots, plants from all over the combination and repetition. The first factor to be tested is biochar kendaga rubber seed shells are: B0 = without biochar, biochar B1 = 0.5 g / plot, B2 = biochar 1.0 g / plot, biochar B3 = 1.5 g / plot. The second factor is chicken manure, namely: A0 = no chicken manure, chicken manure A1 = 1.5 g / plot, chicken manure A2 = 1.0 g / plot, A3 = 0.5 g chicken manure / plot. The results showed that chicken manure can increase growth (plant height, stem diameter) and production (number of tuber per plot, weight of tuber per sample, weight of tuber per plot) potatoes.
