“…When SAP is immersed in water an interaction occurs between SAP and water, the hydration process, and the formation of the hydrogen bonds. The formation of hydrogen bonds occurs between the functional group -COO-in acrylamide which is hydrophilic with H + ions in water (Abidin et. al, 2012).…”

The hydrogel is superabsorbent polymers (SAP) that are biodegradable and can be obtained from polysaccharides, lipids, and proteins. Polysaccharides include cellulose, starch and their derivatives, seaweed extracts such as carrageenan, alginate, pectin, and chitosan. Carrageenan is the result of the extraction of red seaweed sap with an alkaline solution. The main objective of this study was to simultaneously increase the strength and properties of κ-carrageenan SAP film with the addition of glyoxal and acrylamide as crosslinkers. The addition of acrylamide (variated from 1 to 7 % b/v) into the k-Carrageenan based SAP hydrogel compound and the presence of glyoxal as crosslink agent (variated from 0 to 1,0 % v/v). The physical properties of the SAP films were analyze using swelling degree and tensile strength. The structural and morphological properties of composite films were analyzed using Fourier Transform Infrared (FTIR) and Scanning Electron Microscopy (SEM). In addition, the effect of pHs on the releasing drug Poly(vinylpyrrolidone)-Iodine was investigated. This research shows that the addition of acrylamide and glyoxal can improve the physical properties of the modified κ-carrageenan film. Characterization using SEM shows that the addition of glyoxal causes the formation of tissue fibers in SAP. FTIR spectra indicated the formation of cross bonds in modified SAP film at 3294.42 cm-1 (carboxylic acid). The treatment under alkaline conditions will increase drug release ability.Keywords: κ-carrageenan; hydrogels; acrylamide; glyoxal; drug delivery

Microplastics are contaminants resulting from plastic fragmentation with a size <5 mm. The spread of microplastics threatens the imbalance of the environment and organisms in the waters. So it is necessary to know the abundance, size distribution, and correlation between microplastic abundance and water quality parameters. This study used a quantitative descriptive method with purposive sampling. The study parameters included total microplastic abundance, microplastic abundance based on size characteristics, type of microplastic polymer, water quality parameters, and correlation between microplastic abundance and water quality. Calculating the total abundance of microplastics obtained a value range of 3311.11 – 18111.11 particles/m3. The results of the microplastic size distribution got the highest abundance percentage value in the class with a size <50 µm, which was 84.39%. There were eight types of polymers identified, including Polyethylene (PE), Polyvinyl chloride (PVC), Polypropylene (PP), High-density polyethylene (HDPE), Low-density polyethylene (LDPE, Polyethylene terephthalate (PET), Polycarbonate (PC), and Nylon. Water quality measurements obtained temperature range of 17.37-26.63 °C, pH value range of 6.66-8.51, current velocity value range of 0.13-0.8 m/s, DO value range of 4, 32-6.103 ppm, BOD value range of 4.69-6.07 ppm and TSS value range 0.005-0.019 ppm. Correlation analysis using the Canonical Correlation Analysis (CCA) statistical method. The study showed that water quality parameters such as temperature, current velocity, and DO have a high score of 0.95, 0.83, and 0.8.

“…Hasil pengujian fraksi gel dapat dilihat pada tabel 5. Banyaknya fraksi yang tidak terlarut dalam sediaan menunjukkan ikatan silang yang terbentuk dari hidrogel 19 . Berdsarkan hasil pada tabel 5 nilai fraksi gel tertinggi terdapat pada formula 2 yaitu sebesar 14% dimana merupakan kombinasi galaktomanan dan PVP 1:1, sedangkan pada formula 3 yang mempunyai nilai rasio swelling tertinggi memiliki nilai fraksi gel yang rendah dikarenakan semakin tinggi rasio swelling maka akan semakin mudah hidrogel dalam menyerap air, dan semakin banyak rongga yang terdapat dalam hidrogel, sehingga jaringan terikat silang yang terbentuk dalam hidrogel juga akan semakin kecil 20 .…”

Luka merupakan keadaan dimana fungsi normal dari anatomi kulit mengalami gangguan. Keadaan kulit yang terluka dapat menyebabkan beberapa komplikasi serius antara lain infeksi bakteri, timbulnya eksudat, ataupun terbentuknya bekas luka, oleh karena itu diperlukan penanganan pada luka yang sesuai. Salah satu metode penanganan luka adalah dengan balutan luka, namun penggunaan balutan luka konvensional seperti kain atau kasa mempunyai kendala pada pengaplikasiannya. Hidrogel merupakan suatu jaringan polimer dengan cross link sehingga mempunyai sifat tidak larut air namun dapat menyerap cairan biologis dengan baik. Hidrogel dapat terbentuk dari berbagai macam polimer alami, sintesis, maupun kombinasi antara kedua jenis polimer. Kombinasi dari kedua polimer bertujuan untuk meningkatkan viskositas dari hidrogel dan untuk menghasilkan hidrogel dengan sifat fisik yang lentur, transparan, dan lembut. Tujuan dari penelitian ini adalah untuk mengetahui kombinasi polimer galaktomanan dan PVP yang optimal, berdasarkan karekteristik fisik sediaan, serta hasil uji evaluasi rasio swelling, dan fraksi gel. Kombinasi polimer galaktomanan dan PVP yang digunakan adalah 1:0,5; 1:1; dan 1:2. Hasil penelitian menunjukkan bahwa kombinasi polimer galaktomanan dan PVP yang optimal adalah 1:1 dimana menghasilkan karakteristik fisik yang baik, serta hasil uji evaluasi rasio swelling, dan fraksi gel yang baik, dibandingkan dengan penggunaan polimer tunggal pada sediaan hidrogel.
