<p>Kualitas biji kakao fermentasi rendah karena kualitas starter mikroba untuk fermentasi biji kakao rendah. Seleksi starter mikroba diperlukan untuk mendapatkan starter yang unggul. Ada dua jenis starter, yaitu starter cair dan starter kering. Starter cair banyak digunakan untuk fermentasi biji kakao. Starter yang diuji adalah starter cair, yaitu starter Inoka, starter cair BB-Pasca, dan starter <em>yoghurt</em>. Seleksi starter mikroba dilakukan dengan memfermentasi pulp biji kakao selama 24 jam pada berbagai suhu fermentasi (20<sup>o</sup>C, 30<sup>o</sup>C, dan 40<sup>o</sup>C). Parameter yang diamati adalah jumlah total mikroba, laju pertumbuhan mikroba starter, tingkat konsumsi gula pereduksi oleh mikroba starter, total asam yang diproduksi, tingkat penurunan pH, dan peningkatan suhu fermentasi serta korelasi antara parameter pengamatan penelitian. Starter cair unggul yang terpilih adalah starter cair Inoka. Karakteristik starter Inoka adalah memiliki tingkat laju pertumbuhan μ = 0.470, konsumsi gula pereduksi oleh mikroba starter 12%, peningkatan asam total 7%, penurunan pH 5,2, dan peningkatan suhu fermentasi 1,56<sup>o</sup>C serta korelasi antara parameter penelitian di atas 0,61.</p><p> </p><p><strong>Selection of Superior Liquid Starters for Cocoa Beans Fermentation</strong></p><p>The quality of fermented cocoa beans varies because the microbial starter for fermented cocoa beans varies. The selection of starter is needed to get a superior starter. The starter tested is a liquid starter, that is the Inoka starter, the BB-Pasca liquid starter, the yoghurt. The selection of starter is done by fermenting cocoa bean pulp for 24 hours at various fermentation temperatures (20<sup>o</sup>C, 30<sup>o</sup>C and 40<sup>o</sup>C). The parameters observed were total microbial count, microbial growth rate of starter, consumption of reducing sugars by starter microbes, total acid produced, decrease of pH, and increase of fermentation temperature and the correlation between the parameters of the study. The selected superior liquid starter is the Inoka liquid starter. The characteristics of Inoka starter are to have a growth rate of μ = 0.470, consumption of reducing sugars by starter microbes 12%, total acid increase of 7%, decrease in pH 5.2, and increase in fermentation temperature of 1.56<sup>o</sup>C and correlation between research parameters above 0.61.</p>
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
