This study evaluates natural poly-electrolytes from rambutan, jackfruit, and Moringa seeds for turbidity reduction. Moringa showed the best performance (88.93%), followed by rambutan (76.18%) and jackfruit (67.54%). At initial turbidity 62.5 NTU, pH 5 gave the highest removal (91.80%). Efficiency decreased as pH increased. Moringa’s performance was comparable to alum for turbidity levels of 62.5–500 NTU.
