Abstract
Biodiesel is a promising alternative fuel obtained from plant oils and animal fats through the esterification process with alcohol. Lipid microalgae Nannochloropsis sp. can be used as raw material for the production of biodiesel or biofuel with oil content in the microalgae Nannochloropsis sp. as much as 21.3 - 32.7% so, it has the potential to be used as a raw material in making biodiesel. Biodiesel produced from microalgae biomass is the most suitable alternative fuel for the future and environmentally friendly fuel. In microalgae lipid extraction, Nannnochloropsis sp. using several process aids such as autoclave, microwave, and soxhlet. Different types of solvents are used to determine the% yield of lipids present in microalgae. Extraction was carried out to compare the extraction method using autoclave, microwave, and soxhlet to obtain the best method that produced the most substantial % lipid. An autoclave obtained the most abundant lipid yield with n-hexane solvent with a ratio of 3: 1 solvent and algal oil. Thus, this review describes the lipid extraction of the microalgae Nannochloropsis sp. with various extraction aids and different solvent types related to lipid production over the past few years.

Biofuel Fatty Acid Methyl Ester (FAME) or commonly known as biodiesel which can be defined as diesel fuel made from biological materials composed of methyl or ethyl esters, which are obtained by reacting triglycerides and alcohol and have characteristics like diesel oil [1]
Separating process was continued by distillation to separate lipids from solvent methanol
Summary
Abstract⎯ Biodiesel is a promising alternative fuel obtained from plant oils and animal fats through the esterification process with alcohol. Can be used as raw material for the production of biodiesel or biofuel with oil content in the microalgae Nannochloropsis sp. With various extraction aids and different solvent types related to lipid production over the past few years. Alternative energy at this time is needed to meet the needs as a substitute for petroleum. Biofuel FAME or commonly known as biodiesel which can be defined as diesel fuel made from biological materials composed of methyl or ethyl esters, which are obtained by reacting triglycerides and alcohol and have characteristics like diesel oil [1]. Microalgae is one of the potential natural sources in making biodiesel because it contains high oil content.
