“…Not only is that, but the process of separating it using centrifuges is known as "transesterification." Biodiesel, the product of transesterification, has a lower viscosity than regular diesel fuel and can therefore be used in diesel engines (Suzihaque et al 2022). The properties of waste cooking biodiesel and diethyl ether are tabulated in Table 1.…”

The rapid increase in energy demand brought on by the global population boom has led to a surge in the popularity of recycling waste materials into usable energy sources. That is to say, turning trash into usable energy will soon be a hot topic. More and more people are becoming aware of the benefits of biodiesel as a way to lessen their environmental impact by replacing their regular diesel fuel with a cleaner alternative. Usually, biodiesel is produced by mixing vegetable oils with animal-based oils. Because of its low production cost and low environmental impact, waste cooking oil (WCO) is suitable for biodiesel research. Using oxygenated fuels appears to be a practical strategy for lowering engine pollution. The purpose of this study is to examine the effects of varying amounts of diethyl ether (DEE) additives and waste cooking oil biodiesel on the efficiency and emissions of a diesel engine. Emission parameters were evaluated in comparison to those of pure diesel, and results were optimized for various load conditions and mixtures of oxygenated additives.

“…There are two types of methods used in this study. The first method is the method of making POME (Palm Oil Mill Effluent) biodiesel fuel which is better known as the transesterification method [18], and the experimental method for testing direct fuel in diesel engines to determine engine performance results.…”

one way to reduce the scarcity of fuel oil is to make environmentally friendly alternative fuels such as biodiesel. The utilization of biodiesel can be a new energy source and also help reduce the excessive use of fuel, especially diesel and diesel oil in Indonesia. In Indonesia, the amount of palm oil will reach 49.7 tons by 2021, and this data is up 2.9% from the previous year. Palm fruit is processed into CPO. More palm oil processing will produce waste called POME (Palm Oil Mill Effluent). The diesel engine transesterification method is suitable for the manufacture of biodiesel. The amount of base on the catalyst's surface affects the catalyst's activity. So that the higher the base value on the catalyst, the higher the yield of biodiesel that will be produced. The biodiesel produced will be tested on a 4-stroke diesel engine with a B5 and B10 blending composition. The study's results showed that the density and viscosity values for B5 were 5.8 cSt and 810 Kg/m3 and for B10 were 6.3 cSt and 860 Kg/m3. As for engine performance, power, torque, and SFC for B5 fuel at 4000-watt load conditions and 1000 Rpm, engine speeds are 1.18 Kw, 11.28 Nm, and 256.8 gr/Kw. B10 at 4000-watt load condition and 1000 Rpm engine speed is 1.16 Kw, 11.12 Nm, and 269.2 gr/Kw.

“…Biodiesel is a renewable fuel composed of fatty acid methyl esters (FAME). Compared with petroleum diesel, biodiesel has many advantages, such as safety, non-toxic and biodegradable [2]. The use of biodiesel can reduce particulate emissions by up to 75% [3] and also reduces the volume of unburned hydrocarbons, carbon monoxide, and particulate matter, including sulphur dioxide in exhaust emissions [4].…”

“…The production reduced to be 1.05 million liters in 2020 due to the Covid-19 pandemic [5]. Malaysia still has 16 palm biodiesel refineries running today; Selangor (5), Johor (5), Sabah (2), Perak (2), Sarawak (1), and Pahang (1). However, Malaysia's biodiesel production is quite poor, because the total output of palm biodiesel in 2017 only accounted for 40% of its total annual production capacity (2.34 million liters) [6].…”

The transesterification of biodiesel using heterogeneous catalysts has recently caught interest because of its potential to overcome the limitations of homogeneous catalysts. Amongst the heterogeneous catalysts, CaO is well known for its superiority in the transesterification process due to its effectiveness, low cost, and low solubility in methanol. The paper covers the analysis of the transesterification process variables to identify the optimum condition of the process. The effect of process variables, which are catalyst concentration, methanol to oil molar ratio, and reaction temperature, and the interaction between variables on the yield of biodiesel from the esterification of palm oil using CaO catalyst was studied. Response Surface Methodology based on a three-variable central composite design was executed to optimize the process variables. It was found that the concentration of the catalysts is the primary variable affecting the reaction, the molar ratio of methanol to oil is the secondary and the temperature is the ternary. While the interaction between the two variables is not significant in the production of the biodiesel yield. The optimum yield of biodiesel of 98.56% was obtained at a catalyst concentration of 9.63 wt%, methanol to oil ratio of 15.30:1, and reaction temperature of 64.40 °C.
