The poor management of livestock waste products, problems associated with the technology transfer of compost and biochar organic fertilizers not performed in partners, and management issues related to group strengthening are some of the problems found in partners in Buduk village, Badung Bali. The purpose of community service activities is to increase the understanding and skills of partners in converting livestock waste into compost and biochar organic fertilizers that are useful for improving soil fertility and crop yields. The integration of livestock business as a meat producer with its byproducts processed into fertilizer that is ready to be marketed is expected to increase the added value and income of farmers. Therefore, these goals were achieved through counseling, training, mentoring, and technology transfer with direct practice in the field. The results showed that the partner farmer groups tend to receive and implement management of cow manure waste which is immediately processed into environmentally friendly organic fertilizer. They are also able to accept and apply technology to make compost and biochar organic fertilizers that are ready to be marketed. The results also showed that PKM is used by local governments to integrate livestock waste management with the production of organic fertilizer that is ready to be marketed to improve less fertile agricultural land and increase agricultural crop yields.
