Adsorption Of Cr(VI) Ions Using Sugar Palm Fruit Peel (Arenga Pinnata) Immobilized in Ca-Alginate Bead

physiological or metabolic processes that can cause cancer in humans. Adsorption is one of the method that is quite effective for removing Cr(VI) in waters because this method uses low cost with good efficiency. Sugar palm fruit peel waste can be used as an adsorbent because it contains active compounds such as carbohydrates, proteins, fats that can play a role in the absorption of metal ions. This sugar palm peel waste will be immobilized using a Ca-alginate medium to increase the absorption of mechanical forces in the adsorption process. The sugar palm fruit peel was activated using 4% NaOH, which was then immobilized by Ca-alginate. The adsorbent was tested to determine its functional group using FTIR and using SEM EDX to see the surface morphology and the elements present in the adsorbent. The results showed that the optimum absorption of metal ions Cr(VI) using Ca-alginate immobilized palm peel as adsorbent at optimum pH 2 with an efficiency of 63% and adsorption capacity of 0.35396 mg/g, the optimum contact time was 75 minutes with an efficiency of 73, 83% and adsorption capacity of 0.41314 mg/g and the optimum concentration at 150 ppm with adsorption capacity of 13.15185 mg/

Review: Modification of Nanocellulose as Conjugate of Infection-Causing Antibacterial Hydrogel

Infection is the process of entering and reproducing microorganisms such as bacteria, viruses, fungi, and parasites that cause tissue injury. Some of the common types of bacteria that play a role in wound infection are Pseudomonas aeruginosa, Staphylococcus aureus, Escherichia coli, and Staphylococcus epidermis. The antibacterial able to inhibit bacterial growth by inhibiting cell wall biosynthesis, increasing the permeability of the bacterial cytoplasmic membrane, and interfering with the normal bacterial protein synthesis. The aim of this review article is to conduct a study of nanocellulose as an antibacterial hydrogel conjugate. The method used is to summarize information from various recent journals related to nanocellulose, nanocellulose modification, nanocellulose-based hydrogels, and their application as antibacterial. Some journals from primary sources such as the PMC system (PubMed Central), National Library of Medicine (NIH), Science Direct, Elsevier, Nature, ACS Chemical Society, and several other sources. Nanocellulose consists of β-1, 4-glucose, and there are three hydroxyls active at the C2, C3, and C6 positions of the pyranose attachment. Nanocellulose can respond by the reaction of oxidation, esterification, or etherification, by adding a new functional group. Nanocellulose can become nanocellulose nanocrystals (CNC), cellulose nanofibers (NFC), and nanocellulose bacteria (BNC). Nanocellulose formulated in the form of hydrogels and combined with antibiotics will increase the effectiveness in reducing the risk of infection that is resistant to antibiotics
