Isolasi dan karakterisasi alginat dari rumput laut Sargassum polycystum telah dilakukan dengan menggunakan metode jalur kalsium alginat. Proses ini dilakukan dengan cara pengendapan menggunakan CaCl2 dengan waktu 3, 5, dan 7 hari untuk mendapatkan alginat dengan kualitas yang baik. Beberapa parameter yang digunakan untuk pengujian kualitas alginat yaitu uji fisiko-kimia, uji proksimat, dan analisis FTIR, serta uji aktivitas antioksidan. Isolat Ca-alginat SAR-7 menunjukkan hasil bahwa variasi waktu pengendapan sangat berpengaruh terhadap rendemen, yaitu 3,52% dengan kemurnian 32,00%, viskositas 8,74 Cp, pH 7,00, kadar air 19,29%, kadar abu 30,00%, kadar protein 3,50%, kadar lemak 25,07%,dan kadar karbohidrat 22,14%. Analisis FTIR menunjukkan hasil bahwa kalsium alginat mempunyai gugus fungsi â€“OH, C=O, C-O, dan alkil. Hasil uji aktivitas antioksidan menunjukkan bahwa Ca-alginat dengan konsentrasi 50 ppm memiliki bioaktivitas antioksidan dengan kemampuan inhibisi DPPH sebesar 19,57%.Â Kata kunci: Sargassum polycystum, ektraksi, alginat, antioksidan

Research on the adsorption of Mn (II) ions has been carried out using biomass duckweed (Lemna minor linn) with the esterified by citric acid. This study aims to determine the maximum adsorption capacity of Mn (II) ions in using adsorbent biomass of duckweed esterified by citric acid. Water nail biomass adsorbents were characterized using FTIR to determine the functional groups of citric acid esterified adsorbents. The stages of this research include modification of water biomass using citric acid, followed by manganese (II) ion adsorption tests with pH variations in pH, contact time of adsorption and initial concentration variations under optimum conditions. The results showed that optimum adsorption occurred at pH 5, contact time for 10 minutes and the concentration of Mn (II) solution 15 mg / L was measured using atomic absorption spectrophotometry. The equation used in the study follows the Langmuir and Freundlich equations. Based on the Langmuir isotherm equation, the maximum adsorption capacity of Mn (II) ion using citric acid modified water nail biomass is 7,645 mg/ g, the equilibrium constant is 4,317 L/ mol and the adsorption energy is 36,84039 KJ / mol.

The increase of issues on the antibiotics resistant pathogenic bacteria has triggered high exploration for new antimicrobial compounds. One of the potential sources is sponge-associated bacteria. The aim of this study was to get sponge-associated bacteria extract containing antimicrobial activities. On the basis screening of antimicrobial activity using by streaking on agar medium, there were two potential isolates with antimicrobial activities namely LCS1 and LCS2. The two isolates were cultivated,then secondary metabolite product were extracted using methanol as a solvent. Minimum inhibitory concentrations (MICs) of extract LCS 1 were 1,000 μg/well for S. aureus, 950 μg/well for Salmonella sp.and 800 μg/well for Bacillus subtilis. Minimum inhibitory concentrations of extract LCS 2 were 500 μg/well for S. aureus, 1,050 μg/well for Salmonella sp., 750 μg/well for Bacillus subtilis, 350 μg/well for P. aeruginosa, 750 μg/sumur terhadap B. subtilis. Based on the MIC values, the two assay extracts have a relatively low antimicrobial activity. Keywords:Antimicrobial,Sponges associated bacteria,MICs
