  1. ALKALI TANAH SILIKAT NANO PORI SEBAGAI ADSORBEN ASAM LEMAK BEBAS MINYAK KELAPA SAWIT KASAR

  2. LATAR BELAKANG PRODUKSI CPO INDONESIA 2013 = 27,8 juta ton (Dirjen Perkebunan, 2014) 2014 = 31,5 juta ton 2015 = 32,5 juta ton (GAPKI, 2016, Rianto B, 2013) PR (Perkebunan Rakyat) PBS (Perkebunan BesarSwasta) PBN (Perkebunan Besar Negara) PBS (51%) 2013 = 10,4 juta ha (Dirjen Perkebunan, 2014) DOMESTIK 7,20 juta ton PR (42%) ProdukHilir 13,99 juta ton PBN (7%) CPO EKSPOR 20,58 juta ton CPO 6,6 juta ton ALB  5% SNI 01-2901-2006 • Zeolitalam, ALB CPO (kolom 68,07%; batch 17,86%) (WidiAstutidkk, 2006) • Ca-silikat, ALB CPO; 4,47%  0,3% • (Bangundkk, 2015) • - Mg-silikat, ALB CPO; 185 mg/g adsorben (Clowutimon W, dkk, 2011) • - Mg-silikat, ALB Biodisel; 77,39%, 52,57 mg/g adsorben (Assawasaengrat P., 2015) A = 4,79% B = 7,35% C = 10,37% D = 13,34% PENCAMPURAN CPO MgSiO3 (1) CaSiO3 (2) SrSiO3 (3) BaSiO3 (4)

  3. HASIL DAN PEMBAHASAN Analisis SEM-EDX

  4. Analisis XRD dan BET (Puncakdifraksi 20-25) (Puncakdifraksi 40-45)

  5. Analisis GC Puncakserapan wakturetensi 7 – 11 menit ALB CPO A = 4,79%, B = 7,35%, C = 10,37%, D = 13,34%

  6. Adsorpsi ALB CPO A, B, C Dan D MgSiO3 CaSiO3 49,34 – 74,55% 69,88 – 94,78% 63,20% 81,47%

  7. SrSiO3 BaSiO3 52,07 – 93,32% 39,53 – 79,77% 76,59% 60,06%

  8. KESIMPULAN • Adsorsi Asam Lemak Bebas dari CPO dipengaruhi oleh kadar ALB dari CPO dan berat adsorben yang digunakan. • Adsorben Ca-Silikat merupakan adsorben terbaik yang mampu menurunkan kadar ALB rata-rata sebesar 81% • Adsorben terbaik kedua adalah Sr-Silikat sebesar 76%, diikuti oleh Mg-Silikat sebesar 63% dan Ba-Silikat sebesar 60%.

  9. TERIMA KASIH
