      Abstract
      Ulvan oligosakarida merupakan karbohidrat dengan bobot molekul rendah yang dapat ditemukan dalam Ulva sp. Ulvan mengandung 2–10 unit monosakarida linear dan/atau bercabang yang dihubungkan oleh ikatan a-glikosidik dan/atau ikatan ß-glikosidik. Oligosakarida ini didapatkan melalui proses hidrolisis enzimatis, asam, maupun fisik. Tujuan penelitian ini untuk menentukan pengaruh perbedaan metode hidrolisis terhadap karakteristik (bobot molekul, kandungan sulfat, glukosa, asam uronat, rhamnosa, dan xilosa) dan bioaktivitas ulvan oligosakarida. Metode penelitian yang digunakan adalah meta-analisis berupa subgroup analisis yang diawali dengan penelusuran literatur, lalu seleksi literatur, dan kemudian analisis data dengan software OpenMEE. Hasil penelitian disajikan dalam bentuk forest plot dan funnel plot. Hidrolisis enzimatis dengan bantuan enzim ulvan liase, hidrolisis asam dengan H2O2 dan ion exchange resin, dan hidrolisis fisik dengan microwave. Perbedaan metode menunjukkan hasil signifikan pada bobot molekul, kandungan sulfat, dan rhamnosa, namun tidak signifikan pada kandungan asam uronat, glukosa, dan xilosa. Hidrolisis enzimatis menunjukkan bioaktivitas prebiotik, hidrolisis asam menunjukkan bioaktivitas anti-inflamasi, anti-penuaan¸ dan imunomodulator, sedangkan hidrolisis fisik dengan microwave menunjukkan bioaktivitas sebagai antioksidan dan viskoelastis. Hasil penelitian terbaik terlihat pada metode hidrolisis fisik menggunakan microwave. Kata kunci: meta-analisis, metode hidrolisis, ulvan oligosakarida
       
      Ulvan oligosaccharides are low molecular weight carbohydrates found in Ulva sp. Ulvan consists of 2–10 linear and/or branched monosaccharide units linked by a-glycosidic and/or ß-glycosidic bonds. These oligosaccharides are obtained through enzymatic, acid, or physical hydrolysis processes. The aim of this study is to determine the effect of different hydrolysis methods on the characteristics (molecular weight, sulfate content, glucose, uronic acid, rhamnose, and xylose) and bioactivity of ulvan oligosaccharides. The research method used is a meta-analysis with subgroup analysis, starting with a literature review, followed by literature selection, and then data analysis using the OpenMEE software. The results are presented in the form of forest plots and funnel plots. Enzymatic hydrolysis using ulvan lyase, acid hydrolysis with H2O2 and ion exchange resin, and physical hydrolysis using microwave treatment. The differences in hydrolysis methods showed significant effects on molecular weight, sulfate content, and rhamnose levels, but no significant differences were observed in uronic acid, glucose, and xylose content. Enzymatic hydrolysis showed prebiotic bioactivity, acid hydrolysis resulted in anti-inflammatory, anti-aging, and immune-enhancing bioactivity, while physical hydrolysis using microwave generated antioxidant and viscoelastic bioactivity. The best research results were observed in the physical hydrolysis method using microwave treatment. Keywords: hydrolysis methods, meta-analysis, ulvan oligosaccharides
