Calcinite fertilizer or commonly called calcium nitrate fertilizer is a fertilizer that contains two main nutrients namely calcium nutrient and nitrogen nutrient in the form of nitrate. Calcium plays a role as a plant micronutrient and plays an important role especially for the formation and regeneration of plant cell . improving fruit quality and extending the cell life of the fruit producted. The element nitrogen plays an important role in the leaf development, helps the process of photosynthesis so that the capacity of food processing by plant is optimal. The process used in the manufacture of calcinite fertilizers uses calcination and precipitation processes. Calcination is the process of heating of limestone rock with little or no oxygen for the thermal decomposition process. Calcination on process Fertilizer manufacture aims to eliminate organic components and convert calcium carbonate (CaCO3) compound into calcium oxide (CaO) which used as a calcium (Ca) precursor. Prior to the calcination process, the raw materials for calcinate fertilizer, namely beef bones is cleaned of the remnants of fat and dirt which is then finely ground to become a powder. The beef bone powder is then put into the furnace for a calcination process with a temperature ratio of 600˚C, 650˚C, 700˚C, 750˚C and 800˚C for 4 hours. After he calcination process was carried out it was followed by a precipitation process with reacting the calcinate beef bone powder with a solution nitric acid with concentration ratios of 1N, 2N, 3N, 4N and 5N. Precipitation is a method of deposition of each basic material with a reactant, wich in this process uses nitric acid (HNO3) as the reactant. The final process is filtering and drying. This study gave optimum results at a calcination temperature of 800˚C with concentration of 5N, the CaO content is 70.81% and the N content is 49.6%. The composition of calcinite fertilizer based on the Indonesian National Standard (SNI) has a minimum CaO content at least 26% and N at least 15%. Keywords: beef bone, nitric acid, calcium nitrate fertilizer, calcination, precipitation.
