Masyarakat desa Sukaraya kecamatan Pancur Batu umumnya hidup dari hasil ladang dan peternakan, satu diantaranya adalah ternak kambing karena sistem pemeliharaan yang relatif lebih mudah. Kendala yang dihadapi peternak kambing di desa Sukaraya berupa keterbatasan lahan untuk menanam rumput-rumputan, sehingga selain dari lokasi Desa Sukaraya peternak juga harus mengumpulkan rumput dan hijauan dari daerah lain yang langsung diberikan kepada ternak kambing mereka tanpa dilakukan pencacahan sehingga didapati jumlah pakan yang terbuang cukup signifikan, berkisar 25 % sd 35 %. Pengabdian kepada masyarakat ini dimaksudkan untuk memberikan solusi bagi permasalahan mitra tersebut yaitu dengan menyediakan mesin pencacah rumput serta melakukan pelatihan penggunaan dan perawatan mesin. Tahapan pelaksanaannya dengan mendesain mesin sesuai kebutuhan, dilanjutkan dengan proses pembuatan dan ujicoba. Saat pelaksanaan dilapangan kapasitas mesin pencacah dapat mencapai 300 kg per jam. Setelah dilakukan evaluasi pasca pelaksanaan pengabdian masyarakat didapati jumlah pakan yang terbuang berkurang cukup signifikan pada kisaran 5% sd 8% dengan penambahan garam atau konsentrat pada pakan tercacah.

Dusun I Timur Karang Anyar Village Karang Anyar District Beringin Deli Serdang is one of the hamlets where goat breeders still use conventional methods in processing their feed. To provide feed for their goats, farmers have to grind elephant grass, cassava leaves and other forages that grow around the farm site or sometimes from nearby villages. This is quite energy and time consuming for the farmer. If the feed can be stocked for a long period of time, the effectiveness of the farmer's work will be higher. The purpose of this program is to apply appropriate technology to goat farmer groups in processing feed sources by mechanically processing through modernization of livestock with multipurpose animal feed chopping machines, increasing efficiency in the use of goat feed and time effectiveness for raising livestock. This service method is by making a chopping machine for goats that is tailored to the needs of partners and training partners on how to operate and maintain the chopper. With this activity, it is hoped that the efficiency of the use of animal feed and the effectiveness of maintenance time can be increased.

Betta fish is a type of ornamental fish that is very popular during the pandemic, so its selling price has experienced a spike. The reason why this fish is so popular is because of its tiny appearance with unique shape, as well as its extraordinary durability. Betta fish can survive in an aquarium for a long time even if they are not equipped with an aerator or air circulator. Maintenance is relatively easy, cultivation does not require a large space or large capital and can also be done as a home business. Mr. Suwandi, as the prospective service partner, has been running the ornamental fish cultivation business for this type of Betta fish for 5 years, where the fish are kept in tarpaulin fish ponds. There are around 29 fish ponds owned by partners with the number of fish per pond being around 200 to 300. The pool water source is dug well/ring well water where the pool water is replaced every 1.5 months. The quality of pond water greatly influences the sex of the fish produced. Male Betta fish can be sold for IDR 2,000 apiece, while females are only priced at IDR. 300 to 500. Because water quality has a big influence on the selling price, the implementation team added water filter installations after the well and before it flows into the pond. The water quality obtained after carrying out this activity was much better than the water samples obtained previously.

SMA Santo Thomas 4 Binjai merupakan salah satu sekolah swasta Katolik yang cukup dikenal oleh masyarakat kota Binjai. Berdasarkan observasi dan diskusi dengan pihak sekolah, terjadi penurunan prestasi akademik siswa. Selaras dengan jumlah alumni yang diterima di perguruan tinggi negeri juga menurun. Berbagai upaya sudah dilakukan pihak sekolah untuk mendongkrak kemampuan siswa, anatar lain lewat pelajaran tambahan dan penggunaan MS. Power Point untuk presentasi materi pe;ajaran. Secara khusus, penurunan prestasi akademik itu tampak pada mata pelajaran matematika. Guru matematika merasakan kesulitan siswa memahami topik pembelajaran terkhusus perhitungan yang panjang dan pemahaman grafik. Waktu pembelajaran banyak tersita ketika guru menjelaskan grafik fungsi di papan tulis. Eksplorasi materi matemattika secara manual lewat penggambaran di papan tulis kurang efektif. Pelatihan Mathlab Kalkulator Grafik (MKG) diadakan guna mengatasi kendala tersebut. Guru akan semakin dipermudah untuk penyajian grafik fungsi, eksplorasi terhadap grafik, mengoreksi jawaban suatu perhitungan dan juga dalam pembuatan soal. Bagi siswa, lewat pelatihan ini, mereka terbantukan dalam perhitungan yang sifatnya pengulangan, mengoreksi dan menganalisa jawaban mereka apakah sudah tepat atau keliru. Lewat pelatihan yang dilakukan kepada para siswa dan guru, terlihat ada peningkatan kmampuan baik dalam pengenalan, pemahaman dan penggunaan MKG untuk simulasi matematika sederhana. Dari hasil kuisioner yang disebarkan dapat dilihat bahwa para peserta mengalami peningkatan dalam katagori baik dalam pengenalan software simulasi Matematika dari 0 % menjadi 65%, pemahaman lembar kerja Matlab Kalkulator Grafik untuk simulasi Matematika dari 0 % menjadi 60%, penggunaan Matlab Kalkulator Grafik untuk simulasi Matematika dari 0 % menjadi 55%. Hasil ini menunjukan kebaikan dari penggunaan aplikasi MKG sebagai alat bantu dalam pembelajaran matematika.
