Bambang Village has the potential to increase coffee production however, in that village there are problems, namely sloping land and sandy soil, which cause coffee plants to grow less than optimally. This study aims to analyze the effect of applying biopore infiltration holes (BIH) with organic matter on total N and C-organic soil as well as coffee plant growth. This study used a randomized block design with 7 treatments: control (P0), empty biopore infiltration holes (BK), goat manure at a dose of 10 tons/ha (KK1), goat manure at a dose of 20 tons/ha (KK2), compost with a dose of 10 tons/ha (PK1), compost with a dose of 20 tons/ha (PK2), and pine litter with a dose of 10 tons/ha (SP) with 4 replicates. The results showed that KK2 (goat manure with a dose of 20 tons/ha) was the best treatment which affecting total N, organic C, and plant growth. It was seen from the results of the observation of 150 DAA that the total N content was 0.16% (0 - 30 cm) and 0.17% (30 - 60 cm), the C-organic content had an increase of 53% (0 - 30 cm) and 67% (30 - 60 cm), the highest average plant height was 65.12 cm, the number of leaves was an average of 66.25 strands, and the average value of chlorophyll was 440.35 μmol/m2. The relationship between total N content and plant growth shows a positive correlation (strong relationship) with a value of r=0.71 - 0.75. © 2026 Author(s).
