This activity is a community service program carried out by the Institute for Community Service, Universitas Sumatera Utara, through the 2021 Professor Mengabdi scheme grant. The Professor Mengabdi activity team consists of Prof. Dr. Ir. Darma Bakti, MS, and Fuad Hasan, S.Pt, M.Si, who are lecturers of the Agrotechnology Study Program and Animal Husbandry Study Program.
The Berkah Sejahtera group is a collection of several farmers and breeders in the field of guava cultivation and native chickens. Members of the Berkah Sejahtera group in the field of native chicken cultivation have not utilized the feces from the native chickens they raise. After the cage is cleaned and the feces are collected, they are immediately burned. This certainly does not provide benefits or add value to the feces generated from the process of cultivating native chickens. The feces generated from the chickens should be useful and have added value when processed simply into fertilizer. On the other hand, Berkah Sejahtera group members in the field of guava cultivation apply chemical fertilizers to fertilize guava plants. Continuous application of chemical fertilizers can have an adverse impact on soil quality and will ultimately impact the quality of guava produced. The conditions experienced by Berkah Sejahtera members in both guava and native chicken cultivation became the basis for the team to formulate solutions to these conditions. The solution provided by the team was the simple processing of chicken feces into fertilizer. The simple processing is in the form of adding decomposing microorganisms. Furthermore, the team conveyed this to the Berkah Sejahtera group and agreed to carry out the activity.

The activity was carried out at the Berkah Sejahtera group located at Rampah Dua 06, Tuntungan I, Pancur Batu District, Deli Serdang Regency on Sunday, 12 September 2021 at 10.00 - 13.00 WIB. The group members who participated in the activity totaled 26 people, consisting of members in the field of guava cultivation and native chickens. This activity was also attended by 8 USU Faculty of Agriculture students. This activity began with remarks from the Team Leader, Prof. Dr. Ir. Darma Bakti, MS. In the remarks delivered by the team leader, it is hoped that the active participation of group members will be able to take part in training on the simple processing of native chicken feces. This is so that members can make fertilizer from local chicken feces and use it on guava plants. The team leader also appealed to members to commit to applying the fertilizer produced to guava plants so that soil fertility can be maintained. The next activity was the presentation of material and training on the simple processing of native chicken feces by Fuad Hasan, S.Pt, M.Si. The material presented began with the cultivation of good native chickens and the use of feces as fertilizer. After the material was presented, discussions and experience sharing were held with group members. One of the group members, Mr. Bangun, said that the demand for chicken feces is very high, especially to be brought to Berastagi. Where Berastagi is one of the largest vegetable producers in North Sumatra, he also hopes that from this activity, Berkah Sejahtera group members can utilize the chicken feces that are raised for the needs of guava plants.

Furthermore, training activities on the simple processing of native chicken feces to produce fertilizer. The materials used in the processing were 100 kg of chicken feces, 10 kg of bran, 1 kg of molasses, 10 liters of water, and 1 bottle of agricultural EM4. The first stage is mixing 100 kg of feces with 10 kg of bran until evenly distributed. In the second stage, 1 kg of molasses was diluted with 10 liters of water, and 1 bottle of agricultural EM4 was added. In the third stage, the mixture of molasses, water, and agricultural EM4 was then gradually poured into the mixture of feces and bran and stirred until evenly distributed. Then covered airtight (anaerobic) for 14 days. The addition of bran and molasses is to provide nutrients for microorganisms in agricultural EM4 so that these microorganisms can live and reproduce themselves. This is so that the process of decomposing chicken feces can be faster and improve the quality of the resulting fertilizer. After 14 days, the fertilizer can be used as manure.
