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.

The problem that must be overcome by all parties is garbage. Society must take an active role to solve this problem. In an effort to safeguard the environment, the Maju Jaya Waste Bank has a role in sorting and processing waste. Organic waste will become fertilizer. Plastic or non-organic waste will be the raw material for the Paving Blok Prima Lestari Bumi Group. Paving Block Prima Lestari Bumi Group will process plastic waste into paving blocks. However, there are several problems faced. The problem faced by Prima Lestari partner Bumi Paving Blok, such as the lack of supply of raw materials for plastic waste, lack of operational equipment, which causes the production of paving blocks cannot maximize. The level of sales still cannot meet the target per month. Current marketing aspects are carried out by word of mouth and take part in exhibitions carried out by the local government or using social media. For Maju Jaya Garbage Bank, the problem is a large amount of operational costs to sort waste based on the type of waste. This is inversely proportional to income from processed products that are less than optimal. Some of the solutions offered to partners are several parts of training for the sale of goods, procurement of operational goods such as production machinery for paving blocks and machines that can sort waste by type to reduce operating costs.
