Making Liquid Soap From Skin Kapook Tree (Ceiba petandra Gaertn) And Waste Cooking Oil

Waste Cooking oil is a cooking oil that has been used repeatedly. This oil is to used household needs, generally can be reused for culinary concern, but when viewed from its chemical composition, waste cooking oil contains carcinogenic compounds, which occur during frying process (Anonymous, 2011a), so it is quite worrying when we reused for cooking oil to cooking again.

Growth of population, the development of industry, restaurants industry, and fast food business will lead to the production of waste cooking oil in large quantities. This waste cooking oil when consumed can cause diseases that make our body less healthy and decreased body endurance. However, if the used cooking oil is disposed it will inefficient and polluted the environment. Therefore, used cooking oil can be reused, one of them being oil based products such as liquid soap.

Kapok Randu (Ceiba Pentandra (L)) Gaerin many found in Indonesia especially in Java. In West Java, the largest kapook plantation is located in Lebak Wangi and Bandung, at Central Java is located in Pati, Kudus and Jepara areas, while in East Java is located in Tulung Agung, Blitar, Pasuruan , and Banyuwangi. The results of kapok plant are kapok fiber which is widely used in shipping industry, electronics, textile, household, pharmacy and sport equipment industry. Another result of cotton plant is seed. Cotton seeds contain oil commonly used as cooking oil, cosmetics and others. Trees and wood cottonwood contains a lot of potassium and sodium but people more often use the wood as building material and the skin and small branches as firewood, ashes from firewood is still not much to used.

Soap is a compound of sodium or potassium with fatty acids from vegetable oils or animal fats solid, soft or liquid, and foaming. The soap is produced by the saponification process, which is the hydrolysis of fat into fatty acid and glycerol under alkaline conditions. Commonly used base conditions are Sodium Hydroxide (NaOH) and Potassium Hydroxide (KOH). If the base used is NaOH, the reaction product is hard soap (solid), while the base used is KOH, the reaction product is liquid soap (Ketaren, 1986).

ash from the skin,branch, twig kapook wood, wood that has been burned to ashes then soaked in water for about three days, it is intended that the existing potassium in ash and extracted can be used as a base for the manufacture of soap. After three days, it will formed alkaline solution decantation it, after it must measured pH in this research, we obtained the pH is 13-14, it is good enough for the saponification reaction — Soaked Ash

In this study on the use of ash from the skin,branch, twig kapook wood, wood that has been burned to ashes then soaked in water for about three days, it is intended that the existing potassium in ash and extracted can be used as a base for the manufacture of soap. After three days, it will formed alkaline solution decantation it, after it must measured pH in this research, we obtained the pH is 13-14, it is good enough for the saponification reaction

The obtained the pH is 13-14, it is good enough for the saponification reaction — pH measuring

Cooking oil purified using activated carbon derived from coconut shell ashes that have been in the puree, mashed karboan in the mortal then filtered or sieved, activated carbon is used to purify used cooking oil by absorbing impurities in the used cooking oil so that it can be better when in use for the manufacture of soap

A total of 130 grams of cooking oil mixed with 30 grams of KOH solution obtained from the kapok wood burning ash while heated at a temperature of 60 ° C for 1 hour, stirring constantly, mixing aims to form a soap through a saponification reaction, then added water as much as 60 grams to enhance reaction.

Furthermore, to increase the cleaning power of soap and clean power added 5 grams STTP (sodium Tripoli Phosfat) and 5 grams of Texapon, this material serves to soap has made a pretty good power washing.

Soap which has been established then colored to give power to taste good aesthetic value and given fragrance to give fragrance to the soap.

The results have been successfully synthesized liquid soap, viscous and foam, then testing in a manner which is used to clean hands dirty because dirt in the form of dry ink and charcoal from the kitchen pot

Hands that have been polluted with ink and charcoal then given the soap from wood ash cottonwoods that had been made later in the rub on both hand, the results are directly soluble impurities in the soap and liquid soap to black.
