This Community Service activity in the business of making peanut crackers in MSME "SURTAM" aims to improve one of the existing production stages, namely the manufacture of coconut milk. The process of making coconut milk carried out by partners is still traditional which causes the energy used to be quite large and takes a long time. This causes the production of peanut brittle has not been maximized. The method used to solve production problems is to design and manufacture a coconut milk squeezer machine. After that, partners are given training on how to use and maintain the machine in order to carry out maximum production. The benefit of this activity is the synergy between universities and local industries related to the application of appropriate technology that can be used directly by MSME actors in their production activities. There is an increase in the production capacity of partners, especially at the stage of making coconut milk, where before community service activities, the time needed by partners to squeeze the grated 6 coconuts for approximately 1 hour, and after the activity becomes approximately 15 minutes. In addition, partners already have the knowledge and skills in operating and caring for coconut milk extortion machines used in the peanut butter production process.

The need for feed is very important for breeder, especially for chicken and catfish breeders in Indonesia with rapid development, for example breeders in Bangka Belitung to be precise in Sempan village. The high price of feed makes breeders process their own feed simply. In processing, breeders mice and mix the raw materials manually by hand and then ferment then overnight. From these problems, breeders need a machine that can refine feed raw material into one form of feed that is easily digested for livestock, such as pellets. Currently the processing of feed in the form of pellets can be used as an option. Therefore , a design and manufacture of a pellet molding machine was made for chicken and catfish feed with capacity of 10 kg/hour. The design method used in completing this final project is Verein Deutsche Ingineuer (VDI 2222) where this method is planned so that the actions taken are more directed and achieve the expected targets. Based on results of this design, a pellet molding machine design for chicken and catfish feed was obtained using electric motor with a power of 0.5 HP and rotation speed 1400 rpm with pulley and v-belt transmission and horizontal engine system using a screw as suppressor. From the trial results, the machine was able to print pellets with a diameter of 3 mm and 5 mm with capacity of 10 kg/hour.
