Abstract: Patchouli plants are annual plants that can produce essential oils commonly used as mixtures in the cosmetics industry. Patchouli plant cultivation is classified as utilizing a lot of nutrients, so soil types with maximum nutrient content are needed to obtain the best quality production results. Indonesia is a tropical country where many soil models are found with advanced weathering processes. Combination using agricultural waste (biochar) with compound fertilizers is one solution to improve the soil. The research was conducted at Politeknik Negeri Lampung from July 2024 until November 2024, using a split plot with a completely randomized design (CRD). Biochar doses as the main plot (B0 = without biochar, B1 = 12 kg biochar per 12 m2 plot equivalent to 10 tons.ha-1, B2 = 24 kg biochar per 12 m2 plot equivalent to 20 tons.ha-1), and the second factor was in the form of NPK compound fertilizer doses as sub-plots (P0 = without NPK fertilizer, P1 = 8.75 g NPK per plant equivalent to 350 kg NPK fertilizer.ha-1, and P2 = 17.5 g NPK per plant equivalent to 700 kg NPK .ha-1). The results showed that biochar treatment affected the number of branches and the weight of the stump per plant at 160 days after planting, but did not affect plant height. NPK compound fertilizer affected the number of branches, plant height, and the weight of the stump per plant.
