J. curcas has a high content ranging from 25 to 35% (J 2011). It is calculated as 30 % mean of the oil content of Jatropha; then, if the oil yield is 75%, this means from 10 kg of Jatropha crushed, 2.25 kg oil (2.44 l with the density of 0.92 kg/l) is obtained (F et al. 2004; B 2007). Ram press. Various reports in the literature de-scribe the Jatropha’s oil yield using ram press (Ta-ble 1). Commonly, the capacity of a ram press is about 60–65% in 5–6 kg of seeds required to pro-duce 1 l oil and the time required to process 8 kg of seed crops is 8 h (T et al. 2006).In this press, the important variable to increase oil yield is moisture content. e moisture content was determined as a percentage based on original fresh weight, seeds with low moisture content has a high oil yield. In rural areas, the seeds are usually dried under the sun to get low moisture content. Generally, the moisture content is about 5–15% d.b. e ram press is not financially feasible due to its low capacity to extract oil from the seed, its clog-ging and its slow production (B 2006; N 2009). However, the ram press is still recommended
