Abstract

The extent of applications in various fields makes the need for gelatin continue to increase in the global market. Fish gelatin is an alternative to mammalian gelatin and its use is more universal because it can be consumed by all religious followers. The high variability of fish gelatin properties is caused by the availability of many extraction methods to obtain it. This preliminary study was carried out to find the optimum range of gelatin extraction procedures using Red Snapper scales because it had not been widely studied, although it was reported that gelatin yield was not significantly different from the bone and skin part. The optimum condition of the extraction procedure was obtained by pre-treatment using 5 % CH3COOH with extraction temperature of 60 °C which produces 58.19% swelling of fish scales and yield of gelatin is 8.76% with the moisture quality of 6.68%, pH of 6.225, viscosity of 15.54 cP and the melting point of 60 °C. The functional groups of gelatin was also successfully confirmed by FT-IR spectra.

Abstract

This study aims to determine the CO2 adsorption capacity of activated carbon doped with nitrogen. Activated carbon is carbonized from oil palm empty fruit bunches (OPEFB). The results of lignocellulose analysis from OPEFB, 42.87 wt% of hemicellulose, 27.31 wt% of lignin, 23.02 wt% of cellulose and 6.80 wt% of ash. Potassium hydroxide is used as an activating agent and urea as a nitrogen precursor with an OPEFB mass: urea is 1: 1 to 1: 5. The method used is single-step, where carbonization-activation-doping is made into one process. Activated activated carbon is characterized by Fourier-Transform Infrared (FTIR), X-ray diffraction (XRD), Brunauer–Emmett–Teller (BET) isotherm, and scanning electron microscope (SEM) with energy dispersive X-ray. Infrared spectra showed that N-doped activated carbon was successfully synthesized. Diffractogram shows an amorphous structure with graphitic plane (002) and (100). ACN11 produces the highest surface area of 1309.47 m2 g-1. The results of gravimetric CO2 adsorption at 30 °C and 1 atm conditions resulted in the largest CO2 adsorption capacity of ACN14 at 15.02 wt%. The ACN11 and ACN14 adsorption kinetics models followed the intraparticle diffusion model with R2 values of 0.95 and 0.97.
