Mathematics learning model using GeoGebra software has become a handy tool in teaching mathematical concepts and applications. Students can conduct experiments and explore mathematical concepts in an interactive and fun way with GeoGebra software. Using GeoGebra in learning mathematics of two-variable functions can increase students' understanding on the topic discussed, strengthen mathematical computational and visualization skills, and motivate them to know more and better complex mathematical concepts. From this perspective, this study aims to know the impact of using GeoGebra on students' understanding of the derivative of a function of two variables. Furthermore, this study was conducted on two groups of students, namely the control group (not using GeoGebra) of 53 students and the experimental group (using GeoGebra) consisting of 50 students. Based on these results descriptively students in the experimental group have higher scores on the assessment of skills in determining partial derivatives and their application. Statistically, there is a difference between the experimental and control groups in understanding the function of the derivative of the two variables.

In the teaching process, teachers are expected to be creative and innovative in delivering the subject matter of teaching. One of the methods that can be used is visualizing mathematics teaching using GeoGebra software. However, many teachers need help understanding how to use this software. Therefore, training is needed to visualize mathematical concepts to help teachers teach mathematics in their classes. Mathematics teaching can be visualized with the help of GeoGebra so that it can improve student understanding. With this media, concepts, formula derivations, problem-solving, and their applications can be visualized more clearly. This makes mathematics teaching more explorative because students can directly observe the relationship between analytical and visual representations of a concept and the relationship between mathematical concepts. From this activity, partner teachers benefit from increasing their ability to use GeoGebra software to support the teaching and learning process (KBM). The implementation of this training is in three steps. The first step is the formulation of a tutorial module for visualizing mathematics teaching using GeoGebra. The second step is the implementation of training activities which include pretests, explanations of the subject matter, and practices for visualizing mathematics teaching with GeoGebra. The third step is the final evaluation (posttest). At the end of the training, almost all participants mastered the training topics and only a small number had not mastered it. So, it was concluded that the competence of visualizing mathematics teaching with GeoGebra of partner teachers who attended the training increased. This competence greatly supports the implementation of mathematics teaching in the classroom and makes students more enthusiastic.

Nira adalah cairan manis yang diperoleh dari penyadapan batang atau bunga tanaman tertentu, seperti kelapa, aren, dan siwalan. Nira sering diolah menjadi berbagai produk pangan yang bernilai tinggi. Berikut adalah beberapa contoh produk olahan nira yaitu Gula Aren atau Gula Merah, Cuka Nira dan Minuman Tuak. Pengolahan nira di desa Timbuseng sudah sejak lama di lakukan oleh penduduk setempat. Hanya saja produk olahan nira masih memerlukan penerapan teknologi dan inovasi untuk memperoleh hasil yang bisa bersaing di pasaran. Mitra juga masih memerlukan pendampingan pemasaran produk, pelatihan dan pendampingan manajemen usaha. Metode pelaksanaan pengabdian kepada masyarakat yang dilakukan adalah sosialisasi, persentasi, pendampingan, monitoring dan evaluasi program. Hasil kegiatan pengabdian kepada masyarakat adalah meningkatnya pengetahuan dan keterampilan mitra dalam mengolah nira menjadi gula semut dan gula cetak, meningkattnya pengetahuan dan keterampilan mitra memasarkan produk dengan memanfaatkan media sosial, meningkatnya pengetahuan mitra mengenai manajemen usaha serta meningkatnya keterampilan mitra menggunakan teknologi tepat guna untuk membuat gula semut dan gula cetak.
