Yellow passion fruit peel and cupuaçu seeds are common wastes. Usually, they have few or no applications and are discarded, causing environmental pollution. To use them in a new way and reduce ecological pollution, we obtained the ash of yellow passion fruit peels by calcination. We characterized it using Fourier‐transform infrared spectroscopy with attenuated total reflectance (FTIR‐ATR), X‐ray fluorescence (XRF), X‐ray diffractometry (XRD), adsorption‐desorption of N2, scanning electron microscopy (SEM), basicity, and soluble alkalinity. It was observed that the ash was mainly composed of potassium (69%) in the form of carbonate, chloride, and sulfate, with a good surface area (11.23 m2 g−1). The cupuaçu butter was also extracted from the cupuaçu seeds and characterized, showing low acidity, peroxide, saponification, and iodine indexes, in addition to presenting a lipid profile with 57% saturated fatty acid and 43% unsaturated fatty acid. Oleic and stearic acids were present in higher proportions. These results demonstrate that this butter can be a sustainable input in biodiesel production. Thus, the ash was used as a heterogeneous catalyst in the butter transesterification. The biodiesel synthesis was optimized, resulting in 97.8% butter conversion into biodiesel under the following conditions: reaction time of 2 h, 5 wt% of catalyst, 80 °C, and a methanol‐to‐oil molar ratio of 30. This work, therefore, shows that it is possible to obtain and utilize bioinputs, such as cupuaçu butter and passion fruit peel ash, to produce biodiesel through transesterification, and the use of waste materials (precisely passion fruit peels and cupuaçu seeds) makes this method a cost‐effective and environmentally friendly approach to biofuel production.

“…E-mail : 09181006@student.itk.ac.id Many studies have discussed related to biodiesel raw materials and one of the most frequently used materials is palm oil [6]. In the production of palm oil, it cannot be separated from residual waste, this residual waste is commonly referred to as Palm acid oil (PAO) which is residual oil from palm oil effluent (POME) mills [7] [8]. In every CPO (Crude Palm Oil) processing plant, it has not been widely used so that it is disposed of to the environment and tends to pollute the environment.…”

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.
