Published: February 2023

Antioxidant compounds are vital for the body. An imbalance in the body's levels of free radicals and antioxidants will cause oxidative stress and cause disease because free radicals will damage the surrounding molecules (lipids, proteins, and nucleic acids), causing damage to tissues and cells. Today many studies are interested in using natural antioxidants in food, beverages, cosmetics, and therapies derived from plants. Centella asiatica is a plant often used as a source of antioxidants because it contains active compounds such as terpenoids, flavonoids, polyphenols, tannins, carotene, and vitamin C, which have antioxidant activity. In addition to containing 78% menthol, mint leaves contain resin and tannins, which are several polyphenolic antioxidants that prevent or neutralize the effects of free radicals. Antioxidants are compounds that can delay, slow down, or inhibit oxidation reactions and fight free radicals. The results showed that the antioxidant activity of the combination of Centela asiatica leaf extract and mint leaf extract based on the results of the analysis showed that it was included in the strong category.

Kemampuan setiap guru pastilah berbeda. Banyak guru yang belum siap dalam menghadapi perubahan proses pembelajaran termasuk dalam pembelajaran Matematika. Pembelajaran Matematika seharusnya tidak hanya menekankan pada produk akhir, akan tetapi juga berorientasi pada proses. Pembelajaran Matematika membutuhkan visualisasi yang menarik untuk meningkatkan pemahaman siswa dalam belajar. Geogebra merupakan salah satu aplikasi pendukung visualisasi dalam Matematika. Keterampilan guru dalam penggunaan software dan aplikasi untuk pengembangan media pembelajaran dan pendidikan masih sangat kurang. Teknologi penggunaan software baik yang dapat diakses bebas maupun berbayar harus dipelajari sebagai sarana pendukung kegiatan pembelajaran. Kegiatan pengabdian kepada masyarakat ini bertujuan memberikan pendampingan pemanfaatan aplikasi Geogebra bagi guru SD Matematika di Desa Pemulutan Ogan Ilir Sumatera Selatan. Kegiatan diharapkan dapat meningkatkan kemampuan teknologi informasi guru Matematika dalam membuat media pembelajaran. Metode pelatihan yang digunakan adalah metode ekspositori, presentasi, dan tanya jawab. Kegiatan ini dimulai dengan cara instalasi, pengenalan tools yang ada pada software GeoGebra, cara menggunakannya, tutorial hingga evaluasi. Jumlah khalayak sasaran adalah 15 orang guru dan tenaga pendidik di Kecamatan Pemulutan Kabupaten Ogan Ilir. Tim pelaksana kegiatan pengabdian ini terdiri dari 4 orang dosen Jurusan Matematika Fakultas MIPA Universitas Sriwijaya dibantu oleh 10 orang mahasiswa sebagai pembantu pelaksana.

Teori Graf memiliki banyak manfaat dan aplikasi di kehidupan sehari-hari. Pada dasarnya, siswa yang mengenyam pendidikan di sekolah menengah sudah menggunakan graf sederhana sejak usia dini, seperti saat mereka diperkenalkan pada rantai makanan, jaringan listrik, penggambaran struktur molekul, dan lain-lain. Namun sayangnya, mereka tidak mengetahui ilmu sains di baliknya karena mereka tidak pernah diberikan sarana untuk mempelajari Teori Graf secara langsung. Karena itu, melalui kegiatan pengabdian kepada masyarakat ini kami menawarkan solusi dari permasalahan di atas dengan memperkenalkan konsep Teori Graf melalui media pembelajaran di kelas, khususnya untuk siswa kelas X di Madrasah Aliyah Manhalul Ma’arif Darek, Lombok Tengah. Secara umum, kegiatan pengabdian kepada masyarakat ini telah berjalan dengan baik dan lancar. Para siswa terlihat sangat aktif dan antusias dalam mengikuti pembelajaran di kelas. Pengenalan konsep Teori Graf yang diberikan pada dasarnya telah berhasil menjadi media bagi para siswa kelas X di Madrasah Aliyah Manhalul Ma’arif Darek, Lombok Tengah, dalam memberikan sudut pandang baru terhadap pelajaran matematika sehingga mereka lebih tertarik dan antusias dalam belajar matematika serta mengetahui manfaat dan aplikasinya di kehidupan sehari-hari.
