摘要：In this study, we investigated hydrolisis of marine macroalgae biomass from three species Caulerpa racemosa, Sargassum crassifolium and Gracilaria salicornia using three different concentration of sulphuric acid. The result showed that three seaweed species composition consist of mostly carbohydrate in crude fibre form. Caulerpa racemosa has 70.42% carbohydrate with 39.88% crude fibre, which is higher if it is compared to Sargassum crassifolium that has 54.63% carbohydrate with 34.82% crude fibre and Gracilaria salicornia that has 55.44% carbohydrate with 30.97% crude fibre. Reducing sugar compound and hydrolysis efficiency test showed that the highest value was obtained at hydrolysis with 3% (v/v) sulphuric acid, while the lowest was obtained at hydrolysis with 1% (v/v) sulphuric acid. The content of reducing sugar and efficiency of those three species increased along with acid concentration increase in 1% (v/v) to 3% (v/v) sulphuric acid of hydrolysis process. Gracilaria salicornia has the highest reducing sugar compound and hydrolysis efficiency compared to the other species in every addition of sulphuric acid concentration so it has higher potential as bioethanol material compared to Caulerpa racemosa and Sargassum crassifolium.
