“…From the results on the four samples, it was found that absorption peak values were not much different from each sample, namely in Table 3. The wave number 2922-2852 cm -1 shows the stretching vibration group (asymmetric and symmetric) from the alkyl group [24] [15]. The wave number 1800-1700 cm -1 can be indicated by peak -C=O stretching, which is a carbonyl group derived from esters and its presence is in FAME.…”

The increasing need for fossil energy does not equal the availability of alternative energy sources as a substitute generating new problems. In addition to decreasing availability, fossil energy harms the environment by producing dangerous gases from combustion such as carbon dioxide, sulfur, and nitrogen. These factors increasingly encourage researchers to create renewable energy sources with the same performance but are environmentally friendly. Biodiesel or Methyl Ester commonly called Fatty Acid Methyl Ester (FAME) is a renewable alternative energy produced from various raw materials such as animal, vegetable, or other oils. In this study, the methyl ester made from waste cooking oil was processed through two stages of esterification and transesterification using the addition of methanol with different catalysts, H2SO4 and NaOH relying on the reaction step. The research aimed to determine the optimal results from variations in the concentration of the acid catalyst used. From FTIR characterization found that functional groups indicating the formation of methyl esters have been identified at wave numbers 1800-1700 cm-1 with functional groups of -C=O ester the presence of FAME. Meanwhile, to determine the optimum methyl ester caloric value using Bomb Calorimetry according to ASTM D6751 standard. The caloric value was obtained at 9,572.58 Cal/g with catalyst 0,5% H2SO4. The methyl ester content was identified using GC-MS, and the results obtained for ME1, ME2, and ME3 are 74.90%, 77.15%, and 71.98%, respectively. From this study, it can be found that the methyl ester can be produced with esterification-transesterification reactions simultaneously.

“…However, for optimal engine efficiency and longevity, it is essential to utilize only high‐quality, non‐edible oils [127] . Also, since the oils used in biodiesel synthesis can be derived from sources that are not used for food production, the use of non‐edible oils as a feedstock can aid in lowering the level of competition for food crops [128] . A more sustainable energy system may be developed and the sustainability of biodiesel production can be ensured.…”

Biodiesel produced from different edible and non‐edible feedstocks is a viable alternative option for fueling a combustion engine. However, the widespread use of edible sources for biodiesel production may lead to food versus fuel controversy. Oil from non‐edible feedstock is best possible solution for problems that inhibits biodiesel production on commercial scale. This study presents the potential of different non‐edible feedstock for biodiesel production. Several aspects such as extraction technologies used for extracting oil from non‐edible sources and biodiesel production pathways from non‐edible feedstocks are discussed. The quality of biodiesel should be assured before its commercialization by different physical and chemical characterization techniques are used. In particular, the emission comparison of biodiesel derived from the different non‐edible feedstocks is discussed. Based on this study, the non‐edible feedstocks have the potential to produce biodiesel but still it has a long way to go. This is due to non‐edible feedstock is in the R&D phase and needs more research to eliminate additional treatment steps compared to edible feedstock for economic aspects. Furthermore, there has been a trade off in emission properties of biodiesels produced from non‐edible feedstocks which must be removed or evaluated for pilot scale investigations before commercialization.

“…During biodiesel production through this method, there are a number of parameters that should be considered and kept optimized to improve its yield and quality. The common factors include: alcohol to oil molar ratio, temperature of reaction, catalyst concentration and time of reaction [ 14 , 16 , 17 ]. Methanol is the most popular alcohol that has maximum biodiesel yield when compared to that of ethanol and butanol [ 14 , 17 ].…”
