This research aims to determine the adsorption ability of activated carbon and Fe-Cu modified activated carbon in the β-carotene adsorption process on Crude Palm Oil (CPO). Empty Palm Oil Bunches (TKKS) are used as a bio-sorbent for carbon production at a temperature of 500 ºC. The synthesized carbon was activated using H3PO4 and modified with Fe-Cu metal. CPO quality parameters such as Free Fatty Acids and Peroxide Number were analyzed to see the effect of adsorption on CPO quality. The β-carotene level in the CPO sample used is 472.1 ppm. The optimum conditions for using activated carbon in the β-carotene adsorption process are a mass variation of 8 grams with the β-carotene remaining after adsorption being 432.4 ppm, whereas by using Magnetic Activated Carbon, CPO β-carotene after adsorption remains at 426.1 ppm. Meanwhile, increasing the adsorption time causes the absorption of β-carotene to become greater. By using Activated Carbon the remaining β-carotene is 300.1 ppm after 120 minutes, whereas by using Magnetic Activated Carbon the optimum absorption time is faster and the amount of β-carotene absorbed is greater. The remaining βcarotene after absorption with Magnetic Activated Carbon was 288.7 after 90 minutes of adsorption. Apart from being able to absorb β-carotene, magnetic activated carbon is also better at reducing FFA and PV levels from CPO.

Hair plays an important role for humans because hair can influence a person's appearance. Pandan leaves (Pandanus Amaryllifolius) contain compounds in the form of alkaloids, flavonoids, saponins, polyphenols, tannins and dyes. In pandan leaves, the compounds that can provide antimicrobial activity are flavonoids and polyphenols (phenols). This research aims to formulate and test the physical stability of a shampoo combining ethanol extract of jackfruit leaves (Artocarpus heterophyllus) and pandan leaves (Pandanus Amaryllifolius) with varying carbomer concentrations. This research method is laboratory experimental. The carbomer concentration used is 0.1%, 0.3%, 0.5%. The research results showed that the shampoo preparation with the best carbomer concentration was formula 3 with a carbomer concentration of 0.5%. Viewed from an organoleptic perspective, namely with a blackish brown color, the typical smell of pandan accompanied by menthol, pH 6, the shampoo preparation obtained is homogeneous and produces the best foam, namely 13.5 cm in formula 3. Keywords: Shampoo, anti-dandruff, pandan leaves, jackfruit leaf extract.

Silver metal nanoparticles have biocidal properties as a non-toxic inorganic antibacterial agent. Flavonoid compounds from the Turi Leaf (Sesbania grandiflora) plant extract as a natural bio reductant. In the research, UV-Vis spectrophotometric testing parameters and antibacterial soap preparations were carried out. Synthesis and Characteristics of Silver Nanoparticles were carried out, with soap preparations made into 3 formulas with different variations in Agno3 concentration, namely 1 mM, 2 mM, and 3 mM and antibacterial activity tested using well diffusion. The results of the absorption spectrum of Ag nanoparticles show the highest peak at a value of 280-290 nm. In the antibacterial activity test, the greater the AgNO3 concentration in the Ag nanoparticle soap, the greater the inhibition zone created by Staphylococcus aureus bacteria. The optimum concentration in soap preparations is 3 mM producing a wavelength of 300 nm with an absorbance value of 1.105. In terms of antibacterial activity, the most effective way to inhibit the growth of Staphylococcus aureus bacteria is formulation III, with an inhibitory power of 7.69 cm2 .

Lead is a hazardous and toxic metal if it reaches human organs in sufficient doses or if it is present in water. Pb2+ can build up in the brain, causing cancer, disorders of nerve cells, kidneys and mental health as well as problems with male reproduction and resulting in bone irregularities in children. As a result, it is vital to regulate the presence of this metal in water. Biosorption is a heavy metal removal technique that use biomass as an adsorbent. The biosorption method was conducted in this study employing sugarcane bagasse as an adsorbent and batch contacting. Variations in contact duration and stirring speed were tested in this study to determine the influence of contact time and stirring speed on the biosorption process. The study's findings revealed that a contact duration of 60 minutes and a stirring speed of 100 rpm were the best conditions in this research.

This study aims to determine the inhibitory potential of quercetin and its derivatives on the activity of Hendra virus (HeV) 6BK6 protein with its comparator N-Acetyl-D-[1-13C] Glucosamine. This research was carried out using the molecular docking method in order to obtain information related to binding affinity values, inhibition constants, and amino acid residues in the ligand-receptor hydrogen bonds. It was found that the compound quercetin 3-O-xyloside had the lowest binding affinity among the other compounds, namely -6.92 kcal/mol with an inhibition constant of 8.44 µM. In addition, there are four types of amino acid residues in the ligand-receptor hydrogen bonds including ASP304 (1,90 Å), SER301 (2,47 Å), ARG191 (3,18 Å), and MET188 (4.34 Å). In this case it can be concluded that the compound quercetin 3-O-xyloside has been shown to have the potential to inhibit the activity of the HeV 6BK6 protein.
