Abstract
Penelitian ini bertujuan untuk mempelajari cara membuat
katalis heterogen K/γ-Al2O3 untuk reaksi transesterifikasi minyak kelapa
sawit menjadi biodiesel, mempelajari pengaruh katalis homogen KOH
dan katalis heterogen K/γ-Al2O3 terhadap yield biodiesel melalui
transesterifikasi minyak kelapa sawit pada reaktor batch, mempelajari
pengaruh temperatur reaksi dan waktu terhadap yield biodiesel yang
dihasilkan pada reaktor batch, dan mendapatkan yield dan konversi
terbaik dari kombinasi variabel penelitian.
Penelitian ini mengembangkan katalis K/γ-Al2O3. Pembuatan
katalis melalui metode impregnasi KOH pada γ-Al2O3. Kemudian,
dioven selama 24 jam pada suhu 110˚C dan dikalsinasi pada suhu
475˚C selama 4 jam dengan dialirkan gas H2 dan N2. Katalis yang
diperoleh digunakan untuk proses tranesterifikasi biodiesel dengan
variabel massa katalis 0,5; 1; 2 gram, waktu 0; 30; 60; 90; 120 menit
dan suhu 60; 80; 100˚C.
Dari hasil penelitian didapatkan bahwa biodiesel dapat
diproduksi melalui reaksi tranesterifikasi menggunakan katalis K/γ-
Al2O3 dalam reaktor batch. Berdasarkan hasil analisa BET didapat luas
permukaan katalis sebesar 59,538 m2/g. Pengaruh komposisi katalis
terhadap yield biodiesel menunjukkan bahwa semakin besar
penambahan katalis sebanding dengan kenaikan yield biodiesel,
komposisi katalis optimum diperoleh pada massa katalis 1 gram KOH
dan 7 gram K/-Al2O3. Yield biodiesel tertinggi menggunakan katalis
homogen (KOH) dengan yield sebesar 71,752% diperoleh pada kondisi
operasi suhu 60oC dan waktu reaksi 120 menit.

Biodiesel is one of alternative energy for fuel which made
from transesterification reaction between vegetable oil and methanol.
This study aims to learn how to make heterogeneous catalysts K/γ-Al2O3
for palm oil transesterification reaction into biodiesel, study the effect of
KOH homogeneous catalysts and heterogeneous catalysts K/γ-Al2O3 to
the yield of biodiesel through transesterification of palm oil in a batch
reactor, study the effect of reaction temperature and time on the yield of
biodiesel produced in a batch reactor, and get the best yield and the
conversion of a combination of research variables.
This study developes a catalyst K/γ-Al2O3. Preparation of the
catalyst through impregnation method KOH on γ-Al2O3. Then, the oven
for 24 hours at a temperature of 110˚C and calcined at a temperature of
475˚C for 4 hours with H2 and N2 gas flowed. The catalyst obtained is
used to process biodiesel tranesterifikasi with variable catalyst mass of
0.5; 1; 2 grams, time 0; 30; 60; 90; 120 minutes and a temperature of
60; 80; 100˚C.
The result showed that biodiesel can be produced through a
reaction using catalysts tranesterifikasi K/γ-Al2O3 in a batch reactor.
The influence of the catalyst composition of the biodiesel yield show that
the larger the addition of the catalyst is proportional to the increase
biodiesel yield, the optimum catalyst composition is obtained in the
catalyst mass 1 gram of KOH and 7 grams of K/γ-Al2O3. The highest
yield of biodiesel using homogeneous catalyst (KOH) at a yield of
71,752% is obtained at a temperature of 60°C operating conditions and
reaction time of 120 minutes.
