The white jabon fruit (Anthocephalus cadamba Miq.) has potential to be used as a biosorbent for removing various synthetic dye pollutants, including Rhodamine B. This fruit was chosen because it contains a high amount of cellulose, which supports the adsorption process. The adsorption ability is expected to be improved through chemical activation using NaOH and further enhanced by combining wit…
Monstera deliciosa Liebm is a plant that creeps on trees and can be used as an ornamental plant that belongs to the Araceae family. This study aims to isolate and identify secondary metabolite compounds from the n-hexane fraction of M. deliciosa stems and conduct toxicity testing of secondary metabolite extracts from M. deliciosa stems using the brine shrimp lethality test (BSLT) method. Isola…
Palm shell (Elaeis guineensis Jacq.) was a palm oil plantation waste that was useful as an adsorbent because it contained cellulose, which played a role in the adsorption process, including heavy metals that were commonly found in mixed forms in the environment. This study aimed to determine the optimum conditions of stirring speed and temperature for the adsorption of cadmium(II) and iron(III)…
Empty fruit bunches (EFB) of oil palm (Elaeis guineensis Jacq.) are an agricultural waste with potential to be utilized as activated carbon for heavy metal adsorption. The cellulose content within EFB serves as a carbon source, whose effectiveness can be enhanced through an activation process. In this study, activation was carried out using 0.1 M NaOH solution to increase the number of active s…
