Oil is energy needed in life. However, from processing to distribution, this industry is vulnerable to environmental pollution, especially at sea. There are many methods of handling oil spills, sorbents are one of them. The use of sorbents is still limited to synthetic materials. This research was conducted to find the ability of natural and biodegradable sorbent materials, kapok fiber (ceiba pentandra (L.) Gaertn). This research is focused on oil adsorption by simple batch method with modification, contact time, initial concentration, and temperature variations. Results show that adsorption capacity of artificial seawater is 0.109-1.95 g/g, this is proof that kapok has water-repellent properties. Adsorption capacity of oil by physically modified kapok in form of fiber and powder has 47.40 g/g and 28.32 g/g adsorption capacity respectively. Chemical modification with PDMS-SiO2 addition to fiber and powder has 46.99 g/g and 22.64 g/g adsorption capacity respectively. Powder with PDMS-SiO2 and clay addition has 24.50 g/g capacity. Adsorption process model is the temkin isotherm and pseudosecond-order kinetics, Adsorption process is chemisorption and physiosorption. Adsorption thermodynamics show that sorption of kapuk to oil are spontaneously and endothermic. Reusability study found kapok can be use up to the 6th cycle an only decreased <50% capacity.
