Proses produksi biodisel (Fatty Acid Methyl Ester) awal perkembangannya dilakukan
menggunakan katalis homogen (cair) basa atau asam, yaitu menggunakan NaOH atau
KOH dalam metanol atau etanol. Kelemahan katalis homogen adalah tidak dapat
digunakan kembali setelah reaksi selesai. Oleh karena itu saat ini banyak
dikembangkan katalis heterogen untuk dipergunakan dalam reaksi transesterifikasi
untuk konversi trigliserida (minyak nabati) menjadi Fatty Acid Methyl Ester (FAME)
sebagai Biodisel. Biodisel dipilih karena bahan bakar berbasis minyak bumi semakin
menipis dan ramah lingkungan. Katalis heterogen utama yang di gunakan dalam
penelitian ini adalah zeolit Co-ZSM5 Mesopori. Zeolit tersebut berasal dari Na-
ZSM5 mesopori yang di impregnasi oksida cobalt dan dilanjutkan proses kalsinasi
pada suhu 550&#730;C. Sintesis zeolit Na-ZSM5 mesopori dilakukan menggunakan metode
double template menggunakan TPAOH sebagai agen pengarah struktur dan PDDA
sebagai template mesopori. Karakterisasi dari katalis Na-ZSM5 dan Co-ZSM5
dilakukan menggunakan instrumen XRD, FTIR, SEM-EDX, dan BET. Hasil
karakterisasi menunjukkan rasio Si/Al 12,98 dengan loading Co 2,53%w/w. Hasil
tersebut sesuai yang diinginkan, yaitu untuk Rasio Si/Al 10-100 dan loading Co 2,5%
w/w. Uji aktivitas katalis Co-ZSM5 dilakukan melalui reaksi transesterifikasi
menggunakan CPO dan hasil uji katalitik di karaketerisasi menggunakan GC-FID.
Uji katalitik tersebut dilakukan dengan jumlah katalis 10%(w/w) terhadap CPO, suhu
reaksi 95&#730;C dan variasi waktu analisis hingga 10 jam reaksi. Hasil reaksi
menggunakan katalis Co-ZSM5 mesopori diperoleh % yield sebesar 3,478% (b/b),
sedangakan menggunakan katalis Co-ZSM5 mikropori diperoleh % yield, yaitu 3,248
% (b/b). Uji katalitik Co-ZSM5 mesopori pada konversi palm oil (minyak goreng
komersial) memberikan % yield 41,87 % (b/b). Hasil ini menunjukkan bahwa Co-
ZSM5 berpotensi sebagai katalis dalam reaksi transesterifikasi.

<b>ABSTRACT</b><br>
The early development of biodiesel production process has used basic or acidic
homogeneous catalyst such as NaOH or KOH in methanol or ethanol. Hence,
nowadays a lot of heterogeneous catalysts have been developed in
transesterification reaction for triglyceride conversion, usually vegetable oil, to
Fatty Acid Methyl Esters (FAME) as main component of biodiesel. In this work, the
heterogeneous catalyst used is mesoporous CoZSM5 zeolite. The initial mesoporous
NaZSM5 zeolite is synthesized by using double template methods with TPAOH as
structure directing agent and PDDA as mesoporous template. The cobalt (Co)
species was prepared through impregnation with incipient wetness in the zeolite.
The result of characterization on ZSM-5 and Co-ZSM5 shown that the structure of
synthesized zeolite is ZSM5 (XRD pattern), Si/Al ratio is 12.98 and Co loaded is
2.53%(w/w). The mesoporous Co-ZSM5 catalyst activity test was carried out in
transesterification reaction in which Crude Palm Oil (CPO) as substrate was mixed
with methanol in the present of zeolite as catalyst (10% substrate) to be converted to
Fatty Acid Methyl Esters (FAME). The reaction was set at 95&#730;C and the reaction
time was varied from 0 ? 10 h. The product was then measured and analyzed with
GC-FID. In the catalyst testing for the transesterification process, the mesoporous
Co-ZSM5 catalyst gave the biodiesel yield of 3.478% (w/w), while the mikroporous
Co-ZSM5 catalyst gave the biodiesel yield of 3.248 % (w/w). Test of catalytic Co-
ZSM 5 mesoporous on the conversion of palm oil (commercial cooking oil) gave %
yield of 41.87% (w / w). These results indicate that Co-ZSM5 potential as a catalyst
