Abstract

Final year students are required to have the ability to innovate, be creative, have personality, and develop independence in seeking and finding knowledge through realities and field dynamics such as ability requirements, real problems, social interaction, collaboration, self-management, as well as performance demands and achievement targets. In order for students' hard skills and soft skills to be formed strongly, it is felt necessary to provide additional skills, especially those that support the completion of the Final Project. Workshops on the use of the Originlab are quite urgent in research so as to speed up the completion of the Final Project (Thesis) for students interested in Materials. This software is commonly used to prepare XRD, FT-IR, UV-Vis and other spectra that are quite important in materials. In this explanation, a brief description of the XRD data preparation steps is described, starting from data input to quantitative and qualitative data analysis. Data analysis was carried out including determining the value of particle size, FWHM, crystal structure and lattice strain. Workshop participants totaled 20 students and were held for 7 days, from 7 to 15 May 2023 with details of 2 days offline, 1 day online via G-Meet and 4 days of mentoring.

Abstract

Fe is a type of heavy metal that can cause damage to the environment and health. If the concentrations of Fe are more than 1 mg/L, it can lead to toxic effects to the human body. The level of Fe contamination in the environment needs to be controlled to diminish hazardous effects. This can be conducted by modifying a smart material to adsorb the Fe metal. The material modification was carried out by isolating pearl oyster shells (Pinctada maxima) into chitosan as Fe metal adsorbent. The main aim of this research is to identify the ability of chitosan to soak Fe up. To obtain chitosan material, the pearl shells were isolated through 3 stages, namely deproteination, demineralization, and deacetylation. The isolated chitosan powder was identified the typical group forming chitosan using FTIR and the yield of each isolation process was calculated. Meanwhile, the ability of chitosan to adsorb Fe metal was identified through testing using AAS. The results of the calculation of the yield of the chitosan isolation process showed a decrease in mass at each stage. Until the final stage, the powder yield decreases to 32.17% from the initial mass used. In addition, the FTIR results also figure out that chitosan was successfully synthesized in the presence of the OH functional group at a wave number of 3434.660 cm-1 and the NH2 functional group at a wave number of 1626.110 cm-1 with a degree of chitosan deacetylation of 80.534%. It is clear from the results of AAS where the highest adsorption capacity is 33,262 mg/g with an adsorption efficiency of 99,788%. Therefore, the pearl shells have been successfully adjusted into chitosan. Where chitosan is one of the excellent biomaterials to absorb the heavy metal.
