“…In the ratio of 1:23, the yield obtained decreased because the higher the ratio of alcohol used, the higher the glycerol level produced. According to Yunnowati et al, high glycerol in the methyl ester solution will encourage the reaction to turn left to form monoglycerides so that the biodiesel yield will decrease [10].…”

One type of renewable alternative energy that has great potential to be developed is biodiesel. Biodiesel is a fuel consisting of a mixture of mono-alkyl esters of long-chain fatty acids made from renewable sources such as vegetable oils or animal fats. Such as vegetable oils or animal fats. One of the vegetable oil products that can be used as feedstock for biodiesel production is used cooking oil. Used cooking oil is used oil. The purpose of this research is to study the characteristics of the effect of catalyst mass, the ratio of used cooking oil mole to methanol mole, and the effect of adding THF 1:1 co-solvent on the purity of biodiesel using heterogeneous catalyst ash derived from Nipah fruit skin calcined at 500°C for 4 hours. The process variables were transesterification reaction time 60, 90, 120, and 150 minutes, a mole ratio of methanol to oil 1:19, 1:21, and 1:23 with the addition of THF: methanol v/v 1:1 co-solvent. Biodiesel properties such as density, viscosity, moisture content, and acid number were evaluated and compared with the Indonesian National Standard (SNI). The characteristics of biodiesel were obtained with a density of 860.2 Kg/m3 and a viscosity of 2.37 mm2/s. They contained 44.14% Palmitic acid and 43.04% Octadecenoic acid (oleic), following the Indonesian National Standard (SNI). The maximum yield obtained was 93.3598% using a mole ratio of oil: methanol 1:23 at 60°C for 120 minutes, TFT 1:1, and 3% catalyst mass. The results obtained in this study indicate that heterogeneous catalysts made from kapok skin can be used to produce biodiesel. Adding TFT co-solvent can increase biodiesel production and methyl ester yield so that high purity is obtained.

“…Mengatasi hal tersebut, beberapa penelitian melakukan kajian terhadap kualitas POME sebagai biodiesel, penelitian [14] melakukan kajian mengenai pembuatan biodiesel menggunakan POME melalui proses esterifikasi asam sulfat dan transesterifikasi menggunakan katalis basa dengan tujuan menurunkan nilai FFA dan mendapatkan kualitas biodiesel yang sesuai dengan SNI. Pada penelitian [17], menggunakan katalis hidrotalsit pada reaksi esterifikasi dalam menurunkan nilai FFA POME dengan tujuan dapat mengidentifikasi sifat fisika dan kimia biodiesel yang dihasilkan. Penelitian [18] menggunakan Metode Adsorben dengan zeolite pada tahap esterifikasi dengan tujuan dapat menurunkan kadar FFA dari biodiesel POME.…”

The substantial development of the palm oil industry in Indonesia is evident in the high production of Crude Palm Oil (CPO) as the primary product and Palm Oil Mill Effluent (POME) as a byproduct in palm oil mills. POME waste contains emissions that can harm the environment, necessitating proper waste management. This issue can be addressed by transforming the waste into biodiesel, as it still contains Free Fatty Acids (FFA) and triglycerides. The utilization of biodiesel can reduce the reliance on fossil fuels and environmental pollution. The research aims to evaluate the quality of biodiesel based on the SNI 7182:2015 standard, considering parameters such as Free Fatty Acid (FFA), acid value, density, water content, and viscosity through experimental processes involving sulfuric acid esterification and basic catalyst transesterification. The study is expected to provide information on the potential of biodiesel as a vehicle fuel and energy source for colt diesel engines, along with an emission analysis during the transition from biodiesel to solar. The biodiesel produced meets the standards for FFA (0.26%), acid value (0.57 mg/KOH), and density (0.871 g/ml). The waste volume of 490 m3/day generates 5,096 liters/day of biodiesel, sufficient for 23 units of colt diesel engines with 55% efficiency, producing an energy output of 988,902.91 J. The transition to biodiesel fuel can reduce CO2 emissions by 20.4%, NOx by 50%, and HC by 40%.Keywords – Biodiesel, POME, Renewable Energy, Esterification
