Abstract: The design used in this research are Factorial randomized block design consisting of 2 treatment factors, 1 factor of biochar administration from various sources consisted of 4 levels of treatment, namely A0 = control (without treatment), A1 = Using corn cob biochar dose of 10 tons / ha (1 kg / plot); A2 = Using rice husk biochar with a dose of 10 tons / ha (1 kg / plot); A3 = Use pecan shell Biochar with a dose of 10 tons / ha (1 kg / plot). Factor 2, giving cow manure consisting of 4 levels of treatment, namely B0 = control (without treatment) B1 = using cow manure dose of 5 tons / ha (0.5 kg / plot); B2 = using cow manure with a dose of 10 tons / ha (1 kg / plot); B3 = using cow doses of 15 tons / ha (1.5 kg / plot). This research was carried out with 2 replications. The parameters observed in this research are plant height (cm), number of tillers (stems), identification of pests found in rice plants, number of pest populations found in rice plants, percentage of per plot pest attacks, percentage of pest attack, identification of diseases on rice plants, the number of disease populations found in rice plants, the percentage of per plot disease attacks, the percentage of attacks on perumpot disease. The results obtained from this research are that the administration of biochar from various sources has no significant effect on plant height and number of tillers but the administration of cow manure has a very significant effect on plant height and number of tillers.
