“…This was also reinforced by Pitriani (2010) who stated that there was a decrease in the percentage of adsorption because the amine and hydroxyl groups present in the resin were fully bound to other components besides H+ or were already saturated. If the adsorption condition is too long, it is possible that the bound metal ions will be released again or desorption will occur [8]. And according to Firdiyono (2012) another possibility is that the relatively long adsorption process causes the adsorbent pores to shrink [8].…”

Patchouli is the largest non-oil export commodity among essential oil exports in Indonesia. However, the quality of patchouli oil in Indonesia is considered to be very low. Traditional patchouli oil distillation is carried out in a small capacity and uses a simple distillation method based on a large difference in boiling points or one of the volatile components. This process produces poor quality patchouli oil such as acid number more than 8, dark oil, patchouli alcohol less than 30%, and high water content. This is evidenced by the large amount of Fe metal contained in patchouli oil. Patchouli oil produced contains a lot of iron in its yield, so it needs further processing to reduce the Fe content in patchouli oil. The use of resin as an adsorbent for Fe metal is one way to reduce the Fe metal content. Resin weighing 50, 150 and 250 grams was added to 200 ml of patchouli oil. Then the stirring process was carried out with a stirring speed of 200 rpm with time variations of 30, 60 and 90 minutes. The results obtained showed the best adsorption process with Fe content in patchouli oil of 1.42 mg/Kg, contact time of 90 minutes and amount of resin of 250 grams with the largest percentage of removal of 87.5%.

“…The Freundlich equation can also show adsorption processes that are reversible or irreversible, and it does not rule out the possibility that a monolayer adsorption process will form. The adsorption process of dyes dominated by Freundlich isotherm, indicates that the interactions that occur between the adsorbate and the adsorbent are dominated by physical interactions with weak bonds and only involve Van der Waals interactions [27,28].…”

Aluminium metal has corrosion-resistant properties, light and easy to obtain, so it is widely used as a raw material for making soft drink cans. The aluminium content in used cans can be more than 90% and it can be used as raw material for making zeolite. In this study, zeolite was synthesized, and its performance was tested as an adsorbent of water-soluble (Congo red) and water-insoluble (Naphthol blue black) textile dye waste. The method used in this study includes three stages, namely (1) synthesis of zeolite from waste cans as a source of Al and waterglass as a source of Si, (2) characterization of zeolite produced using XRD, FTIR, and SEM, and (3) performance test of zeolite on Congo red and Naphthol blue black dyes with adsorbent weight variation: 0.1 to 0.5 gram in 10 mL of a prepared sample at a concentration of 20 mg/L; contact time variations: 30 to 120 minutes at a speed of 150 rpm; pH variations: 5, 7, and 9; and variations in the initial concentrations of dyes of 10 to 40 ppm. The decrease in dye concentration was measured using a UV-Vis spectrophotometer. The Al content in the used cans obtained is 96.5%. The zeolite was successfully synthesized, and the yield obtained from the zeolite formation reaction was 92.67%. XRD characterization results show the diffraction pattern of a mixture of zeolite-X and zeolite-NaP1 with an average crystal size of 24,08 nm. The purity of the synthetic zeolite for zeolite X was 55.44% and zeolite Na-P1 was 44.53%. FTIR characterization shows the intensity of functional groups T-O, T-O-T or O-T-O, and T-H, where T is Si or Al. Characterization by SEM, synthetic zeolite has the same morphology as Faujasite zeolite. The maximum adsorption capacity of zeolite on Congo red and Naphthol blue black was 321,2921 mg/g and 77,5354 mg/g based on Freundlich isotherm. The optimum conditions for adsorption of Congo red and Naphthol blue black dye were at 0,4 gram and 0.1 gram of adsorbent weight, 30 minutes of contact time, 5 and 7 of pH and 40 mg/L initial concentrations of dyes.

“…Zeolit adalah mineral dengan struktur kristal alumina silikat yang berbentuk framework (struktur tiga dimensi) dan mempunyai rongga serta saluran yang diisi oleh kation logam alkali atau alkali tanah serta molekul air. Ion logam dan molekul air dapat digantikan oleh ion atau molekul lain secara reversible tanpa merusak struktur zeolit, sehingga zeolit dapat berfungsi sebagai adsorben, ion exchange dan katalis (Las, et al, 2012 (Las, 1989).…”

Penelitian ini bertujuan untuk mengetahui karaketristik biodiesel yang dihasilkan dari minyak goreng bekas menggunakan katalis H-Zeolit dan KOH. Biodiesel dibuat dengan mereaksikan minyak goreng bekas dan metanol dalam perbandingan 4:1 (volum) dan suhu 60 oC. Biodiesel yang dihasilkan dengan menggunakan katalis KOH mempunyai densitas 0,85 g/mL dan viskositas 3,09 cSt. Senyawa kimia yang dominan dalam biodiesel adalah metil heksadekanoat (29.90% area), 9-octadecenoic acid (Z)-metil ester (55.80% area). Sedangkan biodiesel yang menggunakan katalis H-zeolit mempunyai densitas 0,78 g/mL dan viskositas 0,35 cSt. Senyawa kimianya adalah metil heksadekanoat (10,85% area) dan 9-octanoic acid (Z)-metil ester (11,97% area). Biodiesel menggunakan katalis KOH memenuhi syarat kualitas biodiesel menurut SNI.
