Abstract
Penelitian ini bertujuan untuk sintesis, karakterisasi, dan evaluasi performa hydrogel berbasis kitosan dari Shrimp Shell Chitosan (SSC) yang dimodifikasi dengan Tetraethylenepentamine (TEPA) melalui proses pembentukan hydrogel. Proses pembuatan SSC hydrogel dilakukan dengan metode Knoor yang melibatkan tahapan demineralisasi, deproteinasi, dan deasetilisasi, diikuti dengan proses crosslinking menggunakan TEPA. Hasil karakterisasi menunjukkan bahwa SSC hydrogel membentuk struktur pori yang lebih besar serta memiliki gugus fungsional amina yang berperan penting dalam proses adsorpsi logam berat (Cu dan Ni). Pengaruh rasio molar antara TEPA dan SSC diamati memberikan dampak signifikan terhadap struktur permukaan SSC hydrogel. Rasio molar optimum sebesar 0,6 menghasilkan volume pori tertinggi sebesar 4,66 × 10¹⁰ µm³, dengan struktur jaringan yang saling menyatu dan luas permukaan yang mendukung efisiensi adsorpsi logam berat. Parameter operasional seperti pH dan waktu kontak juga memengaruhi efisiensi adsorpsi. Kondisi optimum dicapai pada pH 3 dengan waktu kontak 100 menit menghasilkan efisiensi % removal dan kapasitas adsorpsi sebesar 99,31% dan 1,0725 mg/g untuk Cu, 99,44% dan 2,9935 mg/g untuk Ni. Pengujian lanjutan terhadap air limbah electroplating menunjukkan bahwa SSC hydrogel mampu mengadsorpsi logam berat dengan sangat baik. Efisiensi % removal dan kapasitas adsorpsi sebesar 99,03% dan 1,0695 mg/g untuk Cu, 99,12% dan 2,984 mg/g untuk Ni. Hasil ini membuktikan bahwa SSC hydrogel hasil modifikasi TEPA sangat potensial sebagai adsorben ramah lingkungan dalam pengolahan air limbah industri mengandung logam berat, yang mendukung pencapaian tujuan SDGs, terutama dalam hal Clean Water and Sanitation (SDG 6) dengan meningkatkan kualitas air melalui pengolahan limbah cair

This study aims to synthesize, characterize, and evaluate the performance of chitosan-based hydrogel from Shrimp Shell Chitosan (SSC) modified with Tetraethylenepentamine (TEPA) through hydrogel formation process. The SSC hydrogel manufacturing process was carried out by Knoor's method involving demineralization, deproteination, and deacetylization stages, followed by crosslinking process using TEPA. Characterization results showed that SSC hydrogel formed a larger pore structure and has amine functional groups that play an important role in the heavy metal (Cu and Ni) adsorption process. The effect of TEPA molar ratio on SSC was observed to have a significant impact on the surface structure of the hydrogel. The optimum molar ratio of 0.6 resulted in the highest pore volume of 4.66 × 10¹⁰ µm³, with a fused network structure and surface area that supports heavy metal adsorption efficiency. Operational parameters such as pH and contact time also affect adsorption efficiency. The optimum condition was achieved at pH 3 with 100 min contact time, which resulted in % removal efficiency and adsorption capacity of 99.31% and 1.0725 mg/g for Cu, 99.44% and 2.9935 mg/g for Ni. Further testing of the electroplating industry effluent showed that the SSC hydrogel was able to adsorb heavy metals very well. The % removal efficiency was recorded at 99.03% for Cu and 99.12% for Ni, with adsorption capacity of 1.0695 mg/g for Cu and 2.984 mg/g for Ni, respectively. These results prove that the TEPA-modified SSC hydrogel is very potential as an environmentally friendly adsorbent in the treatment of industrial waste containing heavy metals, that supports the achievement of SDGs, especially in terms of Clean Water and Sanitation (SDG 6) by improving water quality through wastewater treatment.
