The first stage to prepare bagasse ash to be synthesized. Furthermore, it will be in a furnace at a temperature of 600°C for 4 hours, then analyzed by SEM, BET, EDX, XRF to determine the morphology, surface area, elements and compounds contained in bagasse ash. The second stage is calcined using H2 gas stream, then TGA analysis. The third stage results from calcination, then hydrothermal with the addition of a molar variation of 10Na2O:xAl2O3 15SiO2: 300H2O namely mixing 3.06 grams of Al2O3, 3.168 grams of NaOH, 1.908 grams of silica from bagasse ash and 20.87 grams of H2O (pH=7). Then the sample will be analyzed using XRD and SEM. The next step will be to test zeolite Y which is synthesized into a metal solution medium, namely Pb2+ 25 ppm. The results of the XRF of bagasse ash contained a SiO2 content of 54% which can be used as a synthetic zeolite with a surface area of 291,761 m2/g, after being synthesized, the surface area of zeolite Y is 648,178 m2/g and % adsorption 97.43% for Pb metal. While commercial zeolite has a surface area of 133.122 m2/g with adsorption % 98.84%.

“…Physics adsorption is adsorption that occurs due to the van Der Waals forces, i.e. intermolecular forces are greater than the intermolecular attractive forces or relatively weak attractive forces between the adsorbate and the surface of the adsorbent, so that the adsorbate can move from one part to another surface of the adsorbent [7]. The difference between chemical adsorption and physical adsorption is based on the homogeneity of the adsorbent and adsorbate, adsorption energy, reversibility, and the thickness of the adsorbent layer.…”

Used cooking oil has the potential to be used as raw material for biodiesel. However, the high Free Fatty Acid (FFA) content in used cooking oil can interfere with the transesterification process. This issue will affect the quality of biodiesel yields. Therefore, FFA content in used cooking oil must be reduced through a pre-treatment process by adding activated carbon adsorbent from charcoal. In this study, the adsorption process was carried out by mixing used cooking oil and activated carbon using 20% NaOH for 3 hours. Then the degumming process was carried out by adding 0.5% v/v HCl from the volume of used cooking oil. Then add 0.5% NaOH by weight of used cooking oil and distilled water gradually, accompanied by heating to a temperature of 120 °C. In the esterification stage, the variables used are the comparison of methanol with a ratio of 1: 2, 1: 4, 1: 6, 1: 8, and 1:10. In this study, the lower acid number obtained from all variables was 2,24 mg KOH/g sample. Meanwhile, the most optimal result was the 1: 2 variables with a density of 0.8531 g/ml, and the kinematic viscosity at 40°C was 4.94 mm2/s.
