dc.description.abstractThe seeds of the jackfruit are one part of the jackfruit that is currently underutilized. Because of the high carbohydrate material in the form of cellulose, several research have attempted to employ jackfruit seeds as an adsorbent. In this study, HNO3 activated jackfruit seeds were modified with the addition of Ca-alginate as methylene blue dye adorben to enhance absorption. The percentage of adsorption effectiveness was determined using a UV-Vis Spectrophotometer, functional groups were determined using FTIR, and surface shape and elemental composition were determined using SEMEDX. Based on the research that has been done, it can be seen that the adsorbent of jackfruit seeds modified with Ca-alginate has the potential to remove methylene blue dye in solution at an optimum adsorbent mass of 3 g and a contact time of 90 minutes with an adsorption efficiency of 97.18%. The results of the FTIR analysis showed an absorption in the fingerprint area of 843 cm-1 which was thought to be a mannuronic acid derived from alginate and a change in the weight fraction of the elements after absorption as measured by SEM-EDX.en_US
