Virgin Coconut Oil (VCO) is coconut oil that has undergone a minimal amount of processing without the use of artificial chemicals. VCO has the greatest lauric acid level of the two oils, with 53.70-54.06%, compared to regular coconut oil of 2.81% and palm oil of 0.45%. VCO is advantageous for health due to its high lauric acid concentration, which also increases endurance and hastens the healing of sickness. Coconut, which comprises water, protein, and fat, is a key component in the production of VCO. These three substances are an emulsion in which the emulsifier is a protein. A chemical known as an emulsifier serves to thicken or stabilize the emulsion. To prevent the blending of the oil and water droplets, a thin layer of coconut fruit protein will bind the droplets of coconut oil. If the emulsion bond is compromised, oil will leak out. On a small scale, centrifugation, fermentation, and enzymatic processes can be used to dissolve the emulsion. Keywords: virgin coconut oil, lauric acid, fermentation, centrifugation, enzymatic.

Rubber industry produces a large amount of wastewater from several stages of processing. The processing is coagulation, grinding, centrifugation, washing, and other mechanical manufacturing that will be disposed of in the environment [1]. The addition of chemicals during the process, like ammonia (latex preservation) and sulfuric acid (skim latex coagulation), can cause the formation of various contaminants in the waste. Wastewater will harm the environmental ecosystem and human health if it is directly discharged [2]. It has been reported that the total dissolved solids (TDS) were 2240 mg/L, total suspended solids (TSS) were 3.512 mg/L, ammonia 94 mg/L, BOD 1340 mg/L and COD 2834 mg/L. This value indicates that wastewater has high contamination and must be treated before being discharged into the environment [3].Rubber industrial wastewater treatment techniques have been carried out in several industries, but still, have limited and low efficiency. In general, the treatment of rubber industry wastewater in the Southeast region is based on biological processes, for example, lagoon systems, oxidation trenches, anaerobic digestion, and activated sludge [2]. However, this process requires a large area and still leaves an odour. This process is suitable for wastewater with less polluted and may not function near residential areas. Another method is the anaerobic method and treatment of activated sludge because of the low operating costs and efficient processing of organic material [4]. However, this process requires considerable maintenance time.

A new technology has been currently developed for the removal of heavy metal waste in water, called biosorption. Biosorption technology has been widely used to remove heavy metals from liquid waste. The potential biomass which can be used as bio sorbent was activated coconut husk waste. By using the continuous flow method and activated coconut husk as bio sorbent, the obtained optimum flow rate and bed height of bio sorbent were 2 mL/min and 0.1 g with adsorption capacity of 188.322 mg/g.
