N2  - The reactivation process of Deoiled Bleaching Earth (DBE) produces Reactivated
Bleaching Earth (RBE). RBE can be used as an adsorbent for Crude Palm Oil
(CPO). One method of DBE reactivation is by using acid, where the type and
concentration of acid affect the DBE activation process. This study aimed to
determine the best acid type, the best acid concentration, and the best combination
of acid type and concentration in the DBE reactivation process. This research used
a factorial Randomized Complete Block Design (RCBD), there were 9
combinations with three repetitions. Acid type factors were HCl (M1), HNO3
(M2), and H2SO4 (M3). Acid concentration factors were 4% (S1), 6% (S2), and
8% (S3). The resulting RBE was analyzed for yield, water content, and pH.
Furthermore, RBE was used to bleach CPO. The Bleached Palm Oil (BPO) was
then analyzed for water content, free fatty acid content, and bleaching efficiency.
Data were analyzed by analysis of variance, followed by Orthogonal Contrast
(OC) and Orthogonal Polynomials (OP) tests. The results showed that the best
acid type was HNO3 (nitric acid), the best acid concentration was 4%
concentration, and the best combination of acid type and concentration was HNO3
(nitric acid) with 8% concentration which produced a yield of 79,97%, pH of 6,73,
moisture content of 3,35%, color bleaching efficiency of 17,29%, BPO free fatty
acid content of 3,58%, and BPO moisture content of 0,18%.

Proses reaktivasi Deoiled Bleaching Earth (DBE) menghasilkan Reactivated
Bleaching Earth (RBE). RBE dapat digunakan sebagai adsorben untuk Crude
Palm Oil (CPO). Salah satu metode reaktivasi DBE adalah dengan menggunakan
asam, dimana jenis dan konsentrasi asam mempengaruhi proses aktivasi DBE.
Tujuan penelitian ini adalah untuk mengetahui jenis asam terbaik, konsentrasi
asam terbaik, serta kombinasi jenis dan konsentrasi asam terbaik pada proses
reaktivasi DBE. Penelitian ini menggunakan Rancangan Acak Kelompok
Lengkap (RAKL) faktorial, terdapat 9 kombinasi dengan tiga kali pengulangan.
Faktor jenis asam yaitu HCl (M1), HNO3 (M2), dan H2SO4 (M3). Faktor
konsentrasi asam yaitu 4% (S1), 6% (S2), dan 8% (S3). RBE yang dihasilkan
dianalisa rendemen, kadar air, dan pH. Selanjutnya, RBE digunakan untuk
memucatkan CPO. Bleached Palm Oil (BPO) kemudian dianalisa kadar air, kadar
asam lemak bebas, dan efisiensi pemucatan. Data dianalisis dengan analisis sidik
ragam, lalu dilanjutkan dengan uji Orthogonal Contrast (OC) dan Orthogonal
Polynomials (OP). Hasil menunjukkan jenis asam terbaik adalah HNO3 (asam
nitrat), konsentrasi asam terbaik adalah konsentrasi 4%, serta kombinasi jenis dan
konsentrasi asam yang terbaik adalah HNO3 (asam nitrat) dengan konsentrasi 8%
menghasilkan rendemen 79,97%, pH 6,73, kadar air 3,35%, efisiensi pemucatan
warna 17,29%, kadar asam lemak bebas BPO 3,58%, dan kadar air BPO 0,18%.
