dc.description.abstractJackfruit seed is a biomass from mature jackfruit processing which has not been used optimally, because only a part of people who have used it as food. Some research have been looking for an alternative way to utilize the jackfruit seed, one of them is the biosorbent. The aim of this study were to optimize the stirring speed and pH biosorbents of jackfruit seed powder activated by HNO3 modified Caalginate in absorbing methylene blue dye. Modified jackfruit seed were tested for its adsorption ability through of pH variations and stirring speed with UV-Vis characterization to determine the adsorbance of methylene blue. The functional groups of the modified adsorbent was analyzed using the FTIR instrument. The surface morphology of the modified adsorbent was analyzed with the SEM instrument. The results showed that the optimum pH and stirring speed of modified jackfruit seed in adsorbing methylene blue were 2 and 200 rpm, with an adsorption efficiency of 85,76%.en_US
