Abstract:

As petrol will soon be exhausted in the near future, Jatropha is going to be one of the substitute candidates for future biodiesel production. Countries of South-East Asia, such as Malaysia, they are going to start the establishment of Jatropha plantations assuming that Jatropha will be the main resource for biodiesel production. A press is commonly used to extract oils from Jatropha. An oil press can be manually driven or engine-powered. In this paper, we will review some available advances focused on mechanical extraction techniques, covering three types of press for Jatropha oil extraction.

Abstract:

Jatropha curcas oil is a seed oil or bio-oil, which has advantages compared to others plant’s seed-oil. The advantage of this oil is due to the fact that Jatropha oil does not compete with the food sector. In this research, the potential carrier oil testing was conducted to seek a way in improving the performance of Jatropha oil as lubricant oil, coolant or biodiesel. For this purpose, Jatropha oil was mixed with the other carrier oils in the variation of 0 – 45 %. Each variation was tested to obtain kinematic viscosity and density values. The results of this research was the carrier oils has

Jatropha germplasm accessions need an assessment of their traits to evaluate the nature and magnitude of the genetic variability among accessions. The objective of this research was to evaluate the phenotypic behavior of 130 Jatropha curcas L. (Jatropha) accessions and the genetic variability of selected Jatropha accessions. The selected variables were assessed between 2008-2014 based on the number of fruits per tree (FP), the number of seeds per fruit (SpF), weight of 100 dry seeds (100SW), seed length (SL), seed width (SW), smallest deviation standard as regular seed production (RP), highest

Abstract:

The challenges of emission of greenhouse gases (GhG) have triggered researchers all over the world to come up with alternative fuel sources that reduce greenhouse gas emissions. One of such alternatives is Biodiesel production from Neem and Jatropha seed oils. However, the presence of Free Fatty Acids (FFA) in the oil obtained from these seeds reduces the yield of produced biodiesel. Two common methods proposed in previous literature to reduce the free fatty acids value are the Esterification and Neutralization methods. This study focused on comparing the esterification and neutralization meth

Abstract This article provides a bibliography discussing the significance of Jatropha as a biofuel crop around the world. In the family Euphorbiaceae, the genus Jatropha contains about 170 species of shrubs and trees (some of which are deciduous, such as Jatropha Curcas L.). It’s a perennial that can withstand dry conditions, grows well in soil with low fertility, and yields a lot of oil per plot. Plants produce seeds for up to 50 years and grow rapidly. Due to its many advantages, jatropha has attracted attention as a potentially useful tropical plant in the expansion of renewable energy sour

One of the alternatives for biodiesel feedstock is oil from Jatropha curcas plant. The advantages ofusing this plant are due to its ability to grow in poor soils, different parts of the plant can also be usedfor different purposes, the by products of biodiesel productions have economic values, and biodiesel ismore environmentally friendly when it is being produced and being used, compared to mineral derivedoils. Although Indonesia has another alternative raw material for biodiesel production, i.e. palm oil,however the use of palm oil will affect its supply for the other sectors that have alrea
