The 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. Penelitian 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.
