In coastal sandy soil, the total nitrogen content ranges from 0.07 to 0.11%, which according to the 2009 Soil Research Institute standards, is categorized as very low. This condition can hinder the growth and development of plants because nitrogen is an important element for plant cell division. This study aims to determine the effect of adding organic municipal waste bokashi fertilizer on soil chemical properties (NH4+ and NO3-) and to determine the effect of fertilization (N) on soil chemical properties (NH4+ and NO3-) in coastal sand. This study used a Factorial Randomized Block Design consisting of two factors, namely the dose of urea fertilizer (U) and organic municipal waste bokashi fertilizer (B) with 6 experimental treatment units and 3 replications. Each experimental polybag contained 1, so that the total number was 18 plants. Data were analyzed using Analysis of Variance (Anova) with a significance level or α: 0.05 and 0.01. The results of the analysis showed that the effect of using urea fertilizer and a combination of urea fertilizer with organic municipal waste bokashi fertilizer did not show a significant difference in the N-NH4+ levels. The results of the statistical analysis of variance indicate that the application of urea fertilizer has a significant impact on the concentration of NO3-, but the application of bokashi fertilizer derived from urban waste and its combination with urea fertilizer does not have a significant impact on NO3- levels. In the results of the analysis of variance at the age of plants 20 HST, the application of urea fertilizer has a very significant effect on plant height, while the application of organic urban waste bokashi fertilizer and its interaction have no significant effect on plant height. This occurs because the combination of nutrients from the two fertilizers has succeeded in supplying essential nutrient needs to support plant growth. Increased plant growth is closely related to the availability of macronutrients, where Nitrogen (N) is one of the important elements. Data from the analysis of variance show that the treatment of organic urban waste bokashi fertilizer and urea on coastal sandy soil shows no significant effect on root length.
