Abstract
Biodiesel is an alternative fuel from renewable sources derived from vegetable oil, one of which is used cooking oil and can be synthesized through a transesterification reaction using a heterogeneous alkaline catalyst. The purpose of this research is to obtain a heterogeneous catalyst for banana peel, to determine the optimal conditions for biodiesel synthesis from used cooking oil with a heterogeneous catalyst for banana peel, to determine the quality of biodiesel products by testing physical properties and chemical properties, and to obtain biodiesel products in accordance with SNI 7182:2015. The research was carried out by calcining the peel of the kepok banana with a furnace at a temperature of 550 and 600. Then the transesterification reaction was carried out by reacting to methanol and catalyst with a concentration of 2% and 3% concentrations to a temperature of 60 for one hour and inserting used cooking oil with a molar ratio of 1:6 and then reacted for 1, 2, and 3 hours. Catalysts were analyzed using FTIR, XRD, SEM-EDX, and BET methods. Biodiesel was analyzed for density, viscosity, yield, flash ℃℃℃point, cetane number, and GC-MS. Produced a heterogeneous catalyst of kepok banana peel with high potassium content, white powder form, with the best operating conditions of biodiesel synthesis at calcination temperature variation of 600℃, reaction time of 3 hours, and a catalyst concentration of 3% with a biodiesel yield of 98.56%, and the resulting biodiesel has met the parameters of SNI 7182:2015.

| Additional Information: | Biodiesel merupakan bahan bakar alternatif dari sumber terbarukan yang berasal dari minyak nabati, salah satunya minyak jelantah dan dapat disintesis melalui reaksi transesterifikasi dengan menggunakan katalis basa heterogen. Tujuan riset ini untuk mendapatkan katalis heterogen kulit pisang kepok, mengetahui kondisi optimum sintesis biodiesel dari minyak jelantah dengan katalis heterogen kulit pisang kepok, mengetahui kualitas produk biodiesel dengan pengujian sifat fisik dan sifat kimia, serta mendapatkan produk biodiesel sesuai dengan SNI 7182:2015. Riset dilakukan dengan mengkalsinasi kulit pisang kepok dengan furnace pada suhu 550℃ dan 600℃. Kemudian reaksi transesterifikasi dilakukan dengan mereaksikan metanol dan katalis konsentrasi 2% dan 3% hingga suhu 60℃ selama satu jam, dan memasukkan minyak jelantah dengan rasio molar 1:6 lalu direaksikan selama 1, 2, dan 3 jam. Katalis dianalisis dengan metode FTIR, XRD, SEM-EDX, dan BET. Biodiesel dianalisis densitas, viskositas, yield, flash point, cetane number, dan GC-MS. Dihasilkan katalis heterogen kulit pisang kepok dengan kandungan kalium yang tinggi, bentuk bubuk berwarna putih, dengan kondisi operasi terbaik sintesis biodiesel pada variasi suhu kalsinasi 600℃, waktu reaksi 3 jam, dan konsentrasi katalis 3% dengan yield biodiesel sebesar 98,56%, dan biodiesel yang dihasilkan telah memenuhi parameter SNI 7182:2015. | ||||||
