N2 - Synthesis of Ni/SiPILC (Silica Pillared Clay) catalyst based on light fraction clay for hydrocracking of High-density Polyethylene (HDPE) plastics into liquid fuels has been carried out. The SiPILC was synthesized using CTAB and TEOS by varying the TEOS/clay mole ratio. The Ni metal was impregnated on the SiPILC with a variation of 2, 4, 6, and 8 wt% of Ni. Hydrocracking of HDPE plastic was carried out using catalysts in a semi-batch stainless steel reactor. The liquid cracking product was analyzed using GC-MS. The results showed that the clay consisted of Montmorillonite, Cristoballite, and Quartz minerals. The highest specific surface area of 571 m2/g was showed by the SiPILC treated by  TEOS/clay mole ratio of 60. Ni 2%/SiPILC achieved the best performance catalyst with the highest acidity of 1.327 mmol/g that produced a liquid fraction of 45.50% (gasoline 55.03 % and diesel 44.96 %) at hydrocracking temperature 450 oC for 1.5 h. The Ni 2% /SiPILC catalyst still performed well after the fifth hydrocracking run, producing a liquid fraction of 41.08 %. Highlights Montmorillonite mineral refinery from early clays. SiPILC synthesis based on the light fraction of clay with the best TEOS/clay mole ratio = 60. Ni 2%/SiPILC catalyst has the best catalytic performance in the HDPE plastic hydrocracking process to produce liquid products with fuel characteristics. The best conditions for the HDPE plastic hydrocracking process with Ni2%/SiPILC catalyst at a temperature of 450oC, 1.5 hours, the liquid product is selective for the gasoline and diesel fuel fractions. Reusing five times of Ni 2%/SiPILC catalyst showed a decrease in catalyst activity.
