This study aims to develop a web-based outpatient information system focused on patient registration and docum…
White jabon fruit (Anthocephalus cadamba Miq.) has the potential to be used as a biosorbent because it contains cellulose, whose adsorption capacity can be enhanced through activation. Activation in this study used NaOH and was combined with humic compounds from peat water, such as humic acid, which is expected to increase the surface area and multiply the active sites on the biosorbent. This s…
The white jabon fruit (Anthocephalus cadamba Miq.) combined with humic acid extracted from peat water, is believed to hold potential as a biosorbent capable of removing various dyes, including Safranin O. This fruit was selected due to its relatively high cellulose content, making it suitable for biosorption applications. The aim of this study is to determine the adsorption capacity and efficie…
White jabon fruit powder (Anthochepalus cadamba Miq.) combined with humic acid from peat water has the potential to be used as a biosorbent in absorbing Crystal Violet dye. Jabon puith fruit is used as a biosorbent because of the cellulose content contained in the jabon fruit itself. The combination with humic acid aims to increase the active sites of the biosorbent in absorbing Crystal Violet …
White jabon fruit (Anthocephalus cadamba Miq.) is one of the biosorbents that has the potential to adsorb methylene blue dye because it has high cellulose content. The ability of white jabaon fruit powder can be improved through activation. Activation using NaOH is expected to increase the surface area and multiply the active sites on the white jabon fruit biosorbent. This study aims to determi…
Acacia bark powder (Acacia crassicarpa) can be used as an adsorbent because it contains cellulose, hemicellulose and lignin which play an active role in the adsorption process. This study aims to determine the contact time, stirring speed and optimum temperature of Rhodamine B dye adsorption by acacia bark powder (Acacia crassicarpa).
