Potensi Biji Nangka Teraktivasi Hno3 Yang Dimodifikasi Dengan Ca-Alginat Sebagai Adsorben Metilen Biru

---

The 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 adsorben 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 SEM-EDX. 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 SEMEDX.
