Pengaruh Lama Pemanasan dan Jumlah Sekam yang Ditambahkan terhadap Jumlah Rendemen dan Mutu Minyak Biji Karet (Havea brasiliensis)

Abstract

The aim of the research was to investigate the effect of the heating and the number rice of hull used on the yield and quality of seed rubber oil.

The research had been performed using factorial Completely Randomized Design, two replicates i.e. the heating time (L) 0, 15, 30 and 45 minutes, and the number of hull (S)-2,5; 5,0; 7,5 and 10,0 %.

The result of the research show that the heating time had highly significant effect on yield, moisture, free fatty acid, peroxide number and color. As the heating time increase the yield, free fatty acid, peroxide number and color increas but the moisture decreased.

The result of research showed that the number rice of hull used had highly significant effect on yield, moisture, free fatty acid, peroxide number and color. As the number rice of hull increased the yield, moisture, free fatty acid, peroxide number and color increased.

The result of the research also show the combination of treatment had highly significant effect on yield, moisture, free fatty acid, peroxide number and color.

The highest rendement and the quality were on LS, and the lowest were on
