Bioethanol Production Process from Mangrove Fruit

Abstract

This study is to investigate the possibility from Bruguiera gymnorrhiza mangrove fruit as a potentional raw material for
bioethanol production, an environmentally friendly and renewable alternative energy. Bioethanol produced through
fermentation and distillation possibility to be used as a mixture of vehicle fuels. In this study, mangrove fruit was processed
through a closed fermentation process using Saccharomyces cerevisiae yeast, then continued with fractional distillation to
obtain ethanol with an alcohol content of 90%, 93%, and 95%. The process starts from cleaning and combining the fruit,
steaming, fermentation for seven days, to the distillation process. From the test results, the high carbohydrate content in this
fruit supports its use as a non-food ingredient for bioethanol. The use of mangrove fruit for bioethanol also supports the
government's commitment to reducing carbon emissions and realizing national energy security.
