Soil quality can be improved through a combination of organic and inorganic fertilizers to increase pakchoy production. The purpose of this study was to study and determine the best combination of household waste compost and NPK fertilizer for pakchoy growth and yield. This study was conducted from June to August 2025 in Anggadita Village, Klari District, Karawang Regency, West Java. The study used an experimental method with a single factor Randomized Block Design (RAK) consisting of 5 treatments and repeated 5 times with treatments P1 (Takakura Compost 15 tons/ha + Mutiara NPK 200 kg), P2 (Takakura Compost 15 tons/ha + Mutiara NPK 250 kg), P3 (Conventional Compost 15 tons/ha + Mutiara NPK 200 kg), P4 (Conventional Compost 15 tons/ha + Mutiara NPK 250 kg), P5 (Murat NPK 250 kg). Observation data were analyzed using F test analysis and further tested with DMRT at the 5% level. The results of the experiment showed no significant effect of the combination of household waste compost and NPK on the growth and yield of pakcoy plants of the Nauli F1 variety. The average values for each observation parameter include plant height at 7 hst (7.90 cm), 14 hst (12.01 cm), 21 hst (16.45 cm), 28 hst (19.91 cm), number of leaves at 7 hst (5.80 leaves), 14 hst (7.20 leaves), 21 hst (9.09 leaves), 28 hst (12.07 leaves), and leaf area (960.91 cm2). Keywords: Pakchoy Nauli F1, Household Waste, Compost, NPK Fertilizer.
