This study aimed to determine the effect of the bioactive compost (arkoba) coconut shell charcoal on the growth and the yield of rice plants (Oryza sativa L.) on alluvial soil. The research was conducted in Mulia Baru Sub-District, Delta Pawan District, Ketapang Regency. This study occurred for four months, starting from February 2018-May 2018. The study used a Completely Randomized Design (CRD) with a dose of coconut shell bioactive compost charcoal treatment using six treatment levels, repeated four times where each replication consisted of 3 plant samples. With the result with 6 x 4 x 3 = 72 plants. The treatment was a0 = without giving ARKOBA, a1 = ARKOBA with a dose of 25 g / polybag (5 tons / ha), a2 = ARKOBA with a dose of 50 g / polybag (10 tons / ha), a3 = ARKOBA with a dose of 75 g / polybag (15 tons / ha), a4 = ARKOBA with a dose of 100 g / polybag (20 tons / ha), a5 = ARKOBA with a dose of 125 g / polybag (25 tons / ha). The parameters observed in the study were: plant height (cm), number of clump tillers (tillers), dry paddy grain weight (g), the weight of 100 grains of clump grain (g). The results showed that the dose treatment of coconut shell bioactive compost charcoal had a very significant effect on the variables, which is plant height, number of tillers, dry paddy grain weight and weight of 100 grains of dry grain. Treatment level a3 gave the best results on all variables observed plant height 88.88 cm, the number of tillers was 28.33 tillers, dry paddy grain weight was 20.52 g, and the weight of 100 dried grain seeds was 2.52 g.
