“…Kitosan tidak larut dalam air, pH lebih besar dari 6,5, dan dalam beberapa pelarut organic seperti alcohol, (CH3)2CO dimetil sulfoksida, , basa, atau dimetil formida asam mineral, namun kitosan dapat larut dalam asam format, asam sitrat, dan asam asetat. Pada penelitian ini diperoleh ketidaklarutan sebesar 80,3% termasuk dalam kategori kelarutan agak sukar larut (Setha et al, 2019).…”

Kitosan adalah biopolimer alam yang dihasilkan dari deasetilasi kitin. Parameter utama yang mengontrol sifat fisikokimia dan biologi kitosan adalah derajat deasetilasi dan berat molekul (BM). Pemanfaatan kitosan belum optimal karena rantai kitosan yang panjang dan mengakibatkan kelarutan yang rendah. Oleh karena itu dilakukannya depolimerisasi untuk memotong ikatan kitosan menjadi rantai pendek. Penelitian ini bertujuan untuk memperoleh kondisi optimum metode depolimerisasi kitosan menggunakan asam asetat (CH3COOH) serta untuk mengetahui karakteristik kitosan berat molekul rendah hasil depolimerisasi. Optimasi proses depolimerisasi menggunakan Design Expert versi 13 dengan metode Box Behnken Design (BBD). Desain eksperimen terdiri dari 17 run dengan 5 center point. Variabel proses dalam penelitian ini, yaitu suhu dengan variasi 60oC; 70oC; 80oC, waktu dengan variasi 30 menit; 45 menit; 60 menit, dan konsentrasi kitosan dengan variasi 1%; 1,5%; 2%. Variabel respon pada penelitian ini yaitu rendemen, berat molekul, dan kelarutan kitosan. Hasil dari penelitian ini diperoleh kondisi optimum pada suhu 80oC, waktu pengadukan 34 menit, dan konsentrasi 1% dengan rendemen sebesar 98.0667%, berat molekul 31.662 kDa, dan kelarutan 19.7%, derajat deasetilasi 98.57%, dan indeks kristalinitas sebesar 32.28%.

“…However, NaOCl is more often used because it produces a pure white color which indicates a complete depigmentation process. The use of acetone in the depigmentation process was not perfect if the color produced was yellowish white (Setha and Rumata, 2019). The most suitable concentration of NaOCl reduces pigment to a maximum of 4%.…”

Blood clams (Anadara granosa) are endemic clams found in Southeast Asia and East Asia. Blood clams are widely consumed by the public as seafood dishes in coastal food stalls. The great potential of blood clams will increase the waste of clam shells produced. The accumulation of shellfish waste will cause pollution and reduce environmental aesthetics. The chitin content in blood clam shells can be used as chitosan. Chitosan is a polymer of -(1-4) glucosamine which is formed when the acetyl group in chitin is substituted by hydrogen to become an amine group. Chitosan has antibacterial and antifungal properties. Isolation of chitosan was carried out through the stages of demineralization, deproteination, and deacetylation. The limited use of laboratories during the pandemic is a major obstacle in the isolation process of chitosan. This study aims to process blood clam shell waste into chitosan in a simple way on a home scale. Processing includes deproteination, demineralization, and deacetylation were done using tools and materials available at home. Laboratory equipment such as beakers could be replaced with pots, the reflux process was replaced by using a cloth to filter, and measuring cups were replaced with glasses. The research used 1500 grams of blood clam shell powder and produced 1050 grams of white chitosan with a slightly hard texture

“…According to the Ministry of Maritime Affairs and Fisheries [10], shrimp production in Indonesia reached 1,217,859 tons in 2021. Shrimp is a commodity with high economic value that is commonly processed but leaves the shell and head underutilized, ranging from 35-50% of their body weight [11]. The deacetylation of chitin into chitosan is an alternative method of handling shrimp waste.…”

The combination of polystyrene and chitosan can form polyelectrolyte (PE) membranes. Polystyrene sulfonate-chitosan (PSS-chitosan) adsorbent membrane can adsorb dodecyl benzene sulfonate (DBS) in laundry wastewater. This study aimed to synthesize, identify characteristics, and formulate adsorption effectiveness by PSS-chitosan membranes. The research methods included converting polystyrene into PSS, isolating chitosan, optimizing geometry, making PSS-chitosan membranes, studying adsorption, and applying membranes to laundry wastewater. The resulting membrane was characterized using FTIR and SEM. The results of the infrared spectra showed vibrations of –OH and –NH2 groups at 3418 cm–1, while the SEM image showed a homogeneous membrane surface. The quality of chitosan isolation from shrimp shells was indicated by the degree of deacetylation of 61.3%. The results of the geometry optimization showed the change in the structure’s total energy after adsorption. The PSS-chitosan membrane is resistant to acids but decomposes under alkaline conditions. Optimum adsorption of PSS-chitosan membrane on DBS occurred at pH 8 for 100 minutes. The adsorption kinetics of the PSS-chitosan membrane follows the first pseudo-order equation. PSS-chitosan membrane adsorption isotherm follows the Langmuir isotherm model with an adsorption capacity and efficiency of 3.97 mg.g–1 and 76.6%, respectively, at 0.6 ppm. At the application stage, the PSS-chitosan membrane could adsorb DBS in laundry wastewater by (62.4 ± 7.2) %.
