“…The viscosity is one of the paramount features of an engine fuel because it plays a key role in the fuel spray, mixture formation and combustion process. A high viscosity leads to reduced fuel atomization and interferes with the injection process (Woo & Kim, 2020). In general, the viscosity of oil seed will be reduced after the transesterification process because the big TAG structures are cracked to the simpler structure of fatty acid methyl ester.…”

The physicochemical properties of Jatropha curcas (JC) seed oils are related to the plant varieties and affect the biodiesel quality when it is used as feedstock. This work investigates the physicochemical properties and feasibility of mutated JC seed oil for biodiesel feedstock. Three mutated JC seed oils, from JC-150, JC-226 and JC-300, were successfully evaluated. The oil contents were determined by using gravimetry methods. The AV, FFA, IV and PV were determined by using titrimetric methods. Types of fatty acids were analyzed by using a GC-FID. The triacylglycerol (TAG) and PE compositions were determined by using a HPLC-ELSD. The results show that the oil contents of JC-150, JC-226 and JC-300 seeds were 48.3%, 45.8%, and 51.7%, respectively. The PE contents in JC-150, JC-226 and JC-300 were lower (approximately 33.4%, 46.9% and 96.4%) compared to the control. The oleic and linoleic acids were two main components of all samples, with compositions in the range 41.82-42.45% and 36.68-37.45%, respectively. The compositions of polyunsaturated and monounsaturated TAG were obtained in the range 71.60-76.22% and 19.62-24.53%, respectively. These results show that the properties of mutated JC seed oils meet with the requirements for biodiesel production.

“…Fuel with a higher viscosity will increase the problem of the atomization process and risk damaging the fuel injector. So that it will result in incomplete combustion and reduced engine performance and cause engine damage due to the deposition of solid particles that cannot be burned [13] [14]. The addition of bio additives which results in a decrease in the viscosity value allows the quality of the fogging to be maximized so that the combustion that occurs will be more complete.…”

Octane, heating, and viscosity value are important parameters that affect fuel quality. These parameters are related to combustion process and energy produced and affect vehicle performance. Main fuel is Pertalite with octane number of 90 (RON). The quality of Pertalite can be improved by adding turpentine oil as a bio-additive. This study analyzes effect of adding turpentine oil on these parameters and vehicle performance. Turpentine oil contains oxygenate, so long-term use has a lower risk to the engine. Various composition of turpentine oil for mixture with Pertalite are 0% (PMT 0%), 10% (PMT 10%), 20% (PMT 20%), and 30% (30% PMT) with a total volume of 100 (ml) of each sample mixture. A centrifuge (200 rpm) was used to ensure sample was evenly mixed. Results show addition of turpentine oil increases octane and heating value. The highest octane and heating values were PMT 30% samples, 94.4 (RON), and 39573.1 (KJ/Kg). Meanwhile, the lowest viscosity value was PMT 10%, which was 0.886 cSt. All fuel samples have a viscosity value according to the standard, which is below 1 cSt, so they can be used for testing on vehicles. Vehicle performance test shows that increase in octane and heating value will be followed by an increase in the number of torque and power. PMT 30% produced the highest torque and power numbers, 25.5 Nm (3000 rpm) and 12.10 hp (4000 rpm). An increase in the torque and power is proportional to the increase in specific fuel consumption, 2,377 Kg/Hour.hp (8000 rpm).

“…It is known as long-chain fatty acid of monoalkyl esters and is formed as a result of chemical reactions between vegetable oil or animal fat and alcohol [3]. It can be produced from a variety of renewable raw materials, including algae, waste cooking oil, non-edible and edible oils, and animal fat [4][5][6]. The transesterification reaction is a typical process for producing biodiesel in the presence or absence of a catalyst [7][8][9].…”

The production of biodiesel from conventional vegetable oils is limited by the high cost and competition with food supply. Therefore, there is a need to explore new and underutilized feedstocks that can provide abundant and low-cost oil for biodiesel production. Livistona jenkinsiana is a palm species that grows in tropical and subtropical regions of Asia. It produces oil-rich fruits that are usually discarded as waste. In this work, biodiesel was produced from Livistona jenkinsiana through transesterification reaction, and the parametric analysis was carried out. The process parameters such as reaction temperature, molar ratio, reaction time, and catalyst amount were studied, and yield (Y) was modelled using response surface methodology (RSM) as a modelling tool in MINITAB@17.1.0 software. A second-order RSM model for biodiesel yield was developed as a function of temperature, catalyst, and the molar ratio, which could predict the biodiesel yield. ANOVA results showed that temperature, catalyst, and molar ratio played an important role in the transesterification process. The optimization result showed that the optimal conditions were attained at a temperature of 61.78 °C, methanol to oil molar ratio 9.25:1, and catalyst concentration of 0.86 wt. %. The highest biodiesel yield predicted was 94.47%. The reaction was carried out at a constant reaction speed of 500 rpm for 1.5 h of reaction time. The physicochemical properties of the produced biodiesel indicate that the biodiesel from Livistona jenkinsiana oil (LJO) is ideal for the production of biodiesel.
