Cooking oil is an important basic ingredient in the frying process with the main function as a heat conductor, adding savory taste, increasing nutritional value, and heat of foodstuffs. If cooking oil is used many times it becomes less good for consumption, this is because the fatty acids contained will be more saturated and will change color Used cooking oil that has been used is called used cooking oil. Used cooking oil is oil that has been used more than two or three times frying, and is categorized as waste because it can damage the environment and can cause a number of diseases. So the use of used cooking oil is carried out by reprocessing it for the manufacture of solid soap. The participants of this activity were PKK mothers in one of the villages in Gresik, this activity consisted of discussions, demonstrations and direct practice. The results of this service activity show that community members are very enthusiastic about participating in this activity, as can be seen from the many questions they ask and their desire to participate in this activity. The practice and demonstration are intended to provide skills to the participants in determining the right formula in making laundry soap from used cooking oil.

Cocoa pod shell waste is the largest waste generated from cocoa plants that will cause problems for the environment if not processed properly. Further processing is needed in order to reduce pollution problems. Fresh cocoa fruit shells have a good nutrient content of 88% dry matter, 11.71% crude protein, 20.79% crude fiber, 11.80% fat and 34.90% extractable material without nitrogen (BETN). However, cocoa pods have a disadvantage when given as sole feed, due to the presence of theobromine in cocoa pods. This substance can inhibit the growth of rumen microbes. It is better to do fermentation first to increase digestibility and livestock liking of the feed. Protein content in cocoa pods can play a role in helping the growth or formation of body cells, especially in young cows and support production needs in adult cows. The crude fiber contained in cocoa pods is a complex carbohydrate that is needed by livestock in launching the digestive process. Meanwhile, fat contained in cocoa pods can play an important role for the growth and development of livestock and become a reserve source of energy. Fat serves as a carrier of vitamins in the body, especially vitamins A, D, E, and K because these vitamins are the type of vitamins that can dissolve in fat.
