dc.description.abstractThe purpose of this research was to determine the type of microorganism and the optimum time of fermentation of fresh fruit bunches to facilitate the release of fruit from bunches and to produce good quality of crude palm oil. The research was using completely randomized design with two factors, i.e type of microorganism (M): (Bacillus subtilis; Aspergillus niger; Trichoderma harzianum; Combination of Bacillus subtilis and Aspergillus niger; and Combinations of Bacillus subtilis and Trichoderma harzianum) and length of fermentation (L ): (20 hours; 40 hours; and 60 hours). The results showed that the types of microbes used in the sterilization treatment without sterilization had very significant effects on the parameters of free fatty acid levels, Deterioration of Bleaching Index (DOBI), beta-carotene levels, peroxide numbers while the fermentation and sterilization treatments had very significant effects on parameters of water content, free fatty acid levels, Deterioration of Bleaching Index (DOBI), beta-carotene level, peroxide number, and oil yield. The length of fermentation time used in the treatment of fermentation without sterilization or fermentation and sterilization treatment had very significant effects on the parameters of water content, free fatty acid levels, Deterioration of Bleaching Index (DOBI), beta-carotene content, peroxide number, and oil yield. The interaction between the type of microbes used and the length of fermentation time on the treatment of sterilization without sterilization had very significant effects on the parameters of free fatty acid levels, Deterioration of Bleaching Index (DOBI), beta-carotene levels, peroxide numbers while the fermentation and sterilization treatment had very significant effects. The parameters of water content, free fatty acid levels, Deterioration of Bleaching Index (DOBI), beta-carotene level, peroxide number, and oil yield.en_US
dc.description.abstractPenelitian ini bertujuan untuk menentukan jenis mikroorganisme dan lama waktu fermentasi tandan buah segar yang optimum untuk memudahkan lepasnya brondolan buah dari tandan dan menghasilkan minyak dengan mutu yang baik. Penelitian ini menggunakan rancangan acak lengkap (RAL) dengan 2 faktor yaitu jenis mikroorganisme (M): (Bacillus subtilis, Aspergillus niger, Trichoderma harzianum, Kombinasi Bacillus subtilis dan Aspergillus niger, serta Kombinasi Bacillus subtilis dan Trichoderma harzianum) dan lama waktu fermentasi (L): (20 jam, 40 jam, dan 60 jam). Hasil penelitian menunjukkan bahwa jenis mikroba yang digunakan pada perlakuan fermentasi tanpa sterilisasi memberikan pengaruh berbeda sangat nyata terhadap parameter kadar asam lemak bebas, Deterioration of Bleaching Index (DOBI), kadar betakaroten, bilangan peroksida sedangkan pada perlakuan fermentasi dan sterilisasi memberikan pengaruh berbeda sangat nyata terhadap parameter kadar air, kadar asam lemak bebas, Deterioration of Bleaching Index (DOBI), kadar betakaroten, bilangan peroksida, dan rendemen minyak. Lama waktu fermentasi yang digunakan pada perlakuan fermentasi tanpa sterilisasi maupun perlakuan fermentasi dan sterilisasi memberikan pengaruh berbeda sangat nyata terhadap parameter kadar air, kadar asam lemak bebas, Deterioration of Bleaching Index (DOBI), kadar betakaroten, bilangan peroksida, dan rendemen minyak. Interaksi antara jenis mikroba yang digunakan dan lama waktu fermentasi pada perlakuan fermentasi tanpa sterilisasi memberikan pengaruh berbeda sangat nyata terhadap parameter kadar asam lemak bebas, Deterioration of Bleaching Index (DOBI), kadar betakaroten, bilangan peroksida sedangkan pada perlakuan fermentasi dan sterilisasi memberikan pengaruh berbeda sangat nyata terhadap parameter kadar air, kadar asam lemak bebas, Deterioration of Bleaching Index (DOBI), kadar betakaroten, bilangan peroksida, dan rendemen minyak.en_US
