This study aims to determine the effect of the use of sludge fertilizer (milk industry waste) which can reduce the dosage of inorganic fertilizers on the growth and quality of pakchoi (Brassica campestris var. chinensis). This research was conducted in Malang city from September to November 2023. This research was conducted using a randomized block design consisting of 2 treatments and 3 replications where the first factor was the use of milk waste sludge and without milk waste sludge where the second factor was the accuracy of the use of inorganic fertilizers consisting of 4 levels, namely Urea 100 kg/ha; Urea 200 kg/ha; NPK 100 kg/ha; NPK 200 kg/ha, so that there are a total of 8 treatments. The results of the study showed that the treatment of giving sludge (milk waste) and Urea 100 kg/ha of mustard greens showed growth in plant height, diameter size, leaf area besides the highest chlorophyll a content was also produced by the treatment of giving sludge (milk waste) and Urea 100 kg/ha. This study proves that by utilizing milk waste sludge, it can reduce the use of inorganic fertilizers, namely Urea at a lower dose, namely 100 kg/ha. © Published under licence by IOP Publishing Ltd.
