Community Service chaired by Prof. Dr. Eng Himsar Ambarita ST.MT, with the theme of innovation and begins with providing consultation on the manufacture of animal feed that uses corn tumpi as a substitute for animal feed ingredients. This activity is aimed at helping the community implement zero waste technology by utilizing agricultural waste and supporting the Sustainable Development Goals (SDGs), which is also a government program.

The team of lecturers and students in their activities carried out socialization on how to make animal feed from corn tumpi and provided an animal feed chopper as well as other supporting equipment to produce quality animal feed. Dozens of Mechanical Engineering students from the Universitas Sumatera Utara who were also present helped demonstrate how to use the animal feed chopper. With the presence of a chopping machine powered by a gasoline engine with a power of 4.4 HP, the corn tumpi can be cut into small pieces then further fermented. After this process is complete, then high quality animal feed can be produced. This machine has been tested for feasibility first in the Department of Mechanical Engineering, Universitas Sumatera Utara before being donated to the Hephata work house.

Prof. Himsar reminded, "Engineers must be close to the community and must be able to make things better". Prof Himsar hopes that the community can keep pace with technological advances, especially in the food sector. The head of Panti Karya Hephata, Reverend Binsar Nababan, welcomed the initiative from the Universitas Sumatera Utara lecturer team and hoped that the two parties would be able to establish better collaborations in the future.

The Community Service Team consists of Dr. Nauas Domu Marihot Romauli, S.TP, M.Eng., Hendrik V., S.T., M.T., Emerson Sinulingga, S.T., M.T., Ph.D and Ir. Morida Siagian, M.T., Ph.D., accompanied by Mechanical Engineering students. (RJ – ©ULC)
