The low production of rice in Indonesia caused by low soil fertility, such as low soil organic content. the efforts to increase soil fertility is the addition of biofertilizers, one of them is Organic Liquid Biofertilizer (LOB). Addition of LOB is expected to increase soil organic carbon, increase rice production and reduce the use of chemical fertilizers. This research was conducted from March to June 2021 in.Pujoasri Village, Trimurjo, Central Lampung. This study used a randomized block design with 4 treatments: P0 (100% chemical fertilizer), P1 (100% chemical fertilizer+15 L Ha−1 LOB), P2 (75% chemical fertilizer +15 L Ha−1) and P3 (50% chemical fertilizer+15 L Ha−1 LOB). This study used Ciherang varieties. The data obtained was analyzed statistically using Analysis of Variance (ANOVA). If the results of the analysis were significantly different among treatments is then performed Duncan test with a level of 5%. The results showed, addition of LOB can increase soil organic carbon, total fungi in soil and weight of grain per clump of rice. Addition of LOB has a highers total carbon in soil, total fungi in soil and weight of grain per clump if compared addition 100% chemical fertilizer. Treatment P3 (50% chemical fertilizer+15 L Ha−1 LOB) very significant effect in increasing soil organic carbon (1,28%) and the total fungi in soil (11,55 x 104 cfu ml−1) if the compared to other treatments. The treatment P3 had the highest weight of grain per clump of rice (44,81 grams) if compared to the addition 100% chemical fertilizer treatment (32,24 grams). With the addition of LOB which can increase rice production, so that it is expected to reduce the use of chemical fertilizers.
