In this day and age, farmers are faced with problems in the field caused by the longterm use of chemical fertilizers. Several efforts have been made to overcome the problems faced by farmers. However, these various efforts did not produce maximum results. Therefore, this study is aimed to overcome the problems faced by farmers, such as the very high price increase of chemical fertilizers and also the negative impacts that can occur with the use of chemical fertilizers in the long term. By using an analytical study on the manufacture of organic NPK granules which were tested on pak choy mustard plants. From this, The author found that making organic NPK granules has a quite good and innovative role and supports farmers in overcoming problems resulting from scarcity and the bad impacts resulting from chemical fertilizers. So, organic NPK granules are an organic fertilizer that can fulfill the nutrients needed to support plant growth and become a forum for farmers to produce good and healthy agricultural land. The author has tested pak choy mustard plants and obtained insignificant results on dry weight by comparing Phonska NPK compared to organic NPK using the T test (Paired sample test) with two treatments, namely organic NPK and Phonska NPK. The organic fertilizer provided is organic NPK based on the probiotic BIONAGA-45, Meanwhile, the chemical fertilizer given is NPK Phonska. Each treatment was repeated 6 times, each replication consisting of 5 sample plants. The application of organic NPK and Phonska was carried out 0 days before planting and 14 days after planting. The parameters observed were number of leaves, plant length, canopy area, wet weight (g)/production weight per plant, and dry weight. Thus, the results obtained for wet weight were significantly different but not for dry weight which was not significantly different. From the data obtained, organic NPK can be a substitute for chemical fertilizers as a nutrient supplement that can meet the needs of production plants.,
