Publisher : Talenta Publisher

The use of Nata De Soya prepared from soybean wastewater as an adsorbent on magnesium (Mg2+) and calcium(Ca2+) cations caused hard water in the boiler raw water at PT. SMART Tbk has been studied. Nata De Soya has been activated with H2SO4 1N before use as an adsorbent for Mg2+ and Ca2+ cations in the boiler raw water. The study resulted demonstrated that the optimum mass of adsorbent to adsorb Ca2+cation was 2.5 g with adsorption capacity at 60.64%. Meanwhile, the optimum mass of adsorbent to adsorb Mg2+cation was 2.0 g with the adsorption capacity at 66.34%. The regenerated Nata De Soya adsorbent has been also studied to adsorb Ca2+and Mg2+ cations. In other aspects, the percentage of Ca2+ and Mg2+ cations decrease by 9.27% and 9.47%, respectively after Nata De Soya treatment to the boiler raw water.

Publisher : Talenta Publisher

The effect of pyrolysis temperature on polycyclic aromatic hydrocarbon and organic acid compounds from oil palm shell liquid smoke has been successfully conducted. In this study, variations of temperature were used at 600 to 950ÂºC with temperature intervals at 50ÂºC. Liquid smokes obtained were characterized using GC-MS and FTIR. The GC-MS and FT-IR analysis results showed the presence of organic acid compounds such as acetic acid and propanoic acid. In contrast, no found polycyclic aromatic hydrocarbons (PAH) compounds. The higher the pyrolysis temperature involved the higher the organic acid contents.

Isolation and characterization of cellulose nanocrystal from oil palm empty fruit bunch (OPEFB), obtained from PTPN IV Adolina, by hydrolysis method using 54% sulfuric acid have been done. The isolation process was carried out in two stages; i.e. Î±-cellulose insulation from OPEFB, followed by isolation of cellulose nanocrystal from Î±-cellulose. OPEFB was de-lignification with 3.5% nitric acid and sodium nitrite, then the residue was treated with 17,5% sodium hydroxide, and bleached with H2O2 10%. Isolation of Cellulose nanocrystal was done using 54% sulfuric acid. The result of transmission electron microscopy (TEM) analysis shows that the diameter of cellulose nanocrystal is 66,6 nm. FTIR spectra show the C-O-C stretch of Î±-cellulose and cellulose nanocrystal at 1141 cm-1, which indicates that there is glycoside bonding in the compound structure. The peak near 3200-3490 cm-1 is representative of the C-H and O-H groups. TGA curves show that Î±-cellulose occurs to decompose at around 315ÂºC, while cellulose nanocrystal occurs to decompose at 163ÂºC. The amount of char residue at 500Â°C in cellulose nanocrystal was remarkably higher compared to Î±-cellulose i.e. 30.5% and 7.2% respectively.

Publisher : Talenta Publisher

The research about comparison study of fabrication and characterization of bead chitosan hydrogel and yarn chitosan hydrogel from high molecular chitosan has been successfully conducted. High molecular chitosan was dissolved into 100 ml of 1, 1.5, and 2% of acetic acid and stirred until the chitosan was dissolved completely. The formed chitosan solution was then taken as much as 6 mL using a syringe and dropped slowly to form small beads into a Petri dish containing NaOH 0.3 M then string into a Petri dish containing acetone 1% and dried at Â±50ÂºC. The bead chitosan hydrogel and yarn chitosan hydrogen results were characterized in which differences of functional groups on chitosan with beads chitosan hydrogel and yarn chitosan hydrogel that occurred in the highest spectra peaks was the band at 3433.29 cm-1, which indicated NH groups on chitosan had changed into an O-H group (3653.18 cm-1) on the bead chitosan hydrogels 1% and yarn chitosan hydrogel 1% which showed the existence of chemical interactions. The yarn chitosan hydrogel has better absorption capability compared to bead chitosan hydrogel. Due to the surface area of the chitosan yarn hydrogel being wider than the beads' chitosan hydrogel.

The research on fabrication and characterization of high molecular chitosan film with hydrogel gelatin has been successfully conducted. High molecular chitosan was dissolved in a solution of 1% acetic acid and gelatin was dissolved with aquadest at Â± 60 ÂºC. The formed chitosan and gelatin solution was poured into the glass plate glass and then dried in an oven at Â± 50ÂºC for 24 hours. Volume number variations of chitosan and gelatin solution were 25% : 75%, 50% : 50%, 75% : 25%, respectively.The formed chitosan was characterized using tensile test, SEM, and FT-IR analysis. The tensile test results showed that film chitosan with no gelatin was 1.280 Mpa compared to the ratio between chitosan solution and gelatin solution were 25%: 75, 50%: 50%, and 75%: 25% which tensile test results were 2.156, 2.840, and 9.604 Mpa, respectively. The FTIR test also showed the difference between chitosan and chitosan-gelatin film functional groups where the band at 3433.29 cm-1, which indicated N-H groups of chitosan and changed to be OH groups in chitosan-gelatin film at 3653.18 cm-1 bands. This study also found that three films produced a relatively smooth surface and not rough.
