Effect Of Duration Of Harvesting Kemiri Sunan On Quality Of Kemiri Sunan Oil

Artikel Kemiri Sunan Berita Perkebunan Highlight

ESTATE CROPS NEWS – Kemiri sunan (Reutealis trisperma (Blanco) Airy Shaw) is a plant that has the potential to produce vegetable oils (Heyne, 1987). The seeds contained in the fruit contain oil with a yield of about 50% (Vossen and Umali, 2002; Herman and Pranowo, 2009). Although it has the same general name as vegetable candlenut which is commonly used for cooking, the kemiri sunan plant cannot be consumed because it contains substances that are toxic to insects and other animals.

Another uniqueness of the kemiri sunan plant is that the kemiri sunan fruit does not need to be harvested, but will fall automatically when it is ripe. Harvest of fallen candlenuts is carried out in accordance with the predetermined harvest time, namely 0 days (picking and falling), 2 days, 4 days, 6 days, 8 days, 10 days, 12 days and 14 days. Kemiri sunan samples were taken from 2 different trees. Based on the test results, the oil content / oil yield contained in the kemiri sunan kernels ranged from 37.04% -54.55%. This is in accordance with the literature which states that the kemiri sunan kernel contains 40-62% crude oil. Therefore, the large amount of oil content in kemiri sunan has the potential to become a bio-energy fuel that is environmentally friendly and does not compete with food (Martin, et al, 2010; Bay, 2007; Aunillah and Pranowo, 2012).

The difference in harvest time affects the yield (content) of the oil produced. Based on observations, there is a trend (pattern) of decreasing oil yield along with the length of harvest. At D-0, the yield of kemiri sunan oil was 54.55% and at D-14, the yield decreased to 37.04%.
