Pine oil is an essential oil obtained by the steam distillation of needles, twigs and cones from a variety of species of pine, particularly Pinus sylvestris. It is used in aromatherapy, as a scent in bath oils, as a cleaning product, and as a lubricant in small and expensive clockwork instruments. It is naturally deodorizing, and antibacterial. It may also be used varyingly as a disinfectant, massage oil and an antiseptic. It is also used as an effective organic herbicide where its action is to modify the waxy cuticle of plants, resulting in desiccation.
Coconut oil can be used directly into diesel fuel properly. Coconut oil has a viscosity of 50-60 centi stokes, while diesel 5 centi stokes. At a temperature of between 80-90 degrees Celsius, coconut oil has a viscosity similar to diesel. One innovation that dikembang Department of Agricultural Engineering IPB is by utilizing the exhaust temperature to change the viscosity of the oil to be the same with diesel. The flue gas exhaust has a temperature of 350-360 degrees Celsius so that the required cooling coil to reduce the temperature of the exhaust. Then the oil via a tube is passed through the exhaust before heading into a diesel engine combustion chamber. This way is certainly cheaper than utilizing kokodiesel, namely palm oil industry that has gone through a process to be converted into biodiesel. Kokodiesel price of about Rp. 10,000 per liter, while coconut oil is not through the treatment process can be much cheaper. In addition, the coconut is a common plant that grows in coastal areas, making it a potential source of fuel for local fishermen who tend to have difficulty fuel, both issues of price and availability. Coconut oil is used is coconut oil which has been through a heating process to remove free fatty acids.
