The Farmer Exchange Rate (FER) is one of the indicators in determining the welfare level of farmers. Every month this large FER has a change especially at the end of each season during harvest, the price game especially from producers often occurs so that not a few farmers complain and suffer losses. Therefore, there need to be efforts from the government is looking at past data trends to find the amount of FER in the future so that policies can side with farmers. Artificial Intelligent with a multilayer Back Propagation method is very good for modeling and forecasting of data series in the past with data input in the form of a matrix mxn. The simulation results show that in 2020 in NTB there is an average increase in the exchange rate of farmers of 118.76%, this means that farmers are experiencing a surplus or farmers’ incomes are rising more than their expenditures. However, it appears that from June-August and October-November there was an average decrease of 2%, although overall there was increase of 2.076%. This result was obtained by the construction of a network architecture of two hidden layers where theMSE of 0.12, and MAPE of 0.23.

This study is research on the development of edutainment-based mathematics learning media on social arithmetic material at the seventh-grade junior high school level and using macromedia flash 8. The purpose of this study was to determine how the development of edutainment-based learning media at the seventh-grade junior high school level, and how appropriate the learning media was. edutainment-based mathematics in mathematics learning, as well as to determine the responses and interest of students to the development of edutainment-based learning media at the seventh-grade junior high school level. The development model used in this study is the ADDIE development model which consists of five stages, namely Analysis, Design, Development, Implementation, and Evaluation. In the implementation stage, the researcher limited the trial to a small scale with 15 students. The results of this study obtained a validation level of 90% by material experts, 91% by media experts, 82.4% of students expressed interest, which means that the development of edutainment-based mathematics learning media is feasible and valid as a mathematics learning media.

Mitra kegiatan PKM ini adalah dua sekolah mitra UMSU, yakni SMP Satu Nusa Binjai dan SMA Satu Nusa Binjai. Guru-guru pada dua sekolah tersebut diberikan pelatihan pembuatan media kuis interaktif online quizizz. Target khusus yang ingin dicapai melalui pelaksanaan kegiatan PKM ini menghasilkan guru-guru melek teknologi dalam melaksanakan pembelajaran dan evaluasi pembelajaran secara daring/online. Guru yang mendapat manfaat dari kegiatan pelatihan ini diharapkan dapat memberikan informasi dan pengimbasan kepada guru-guru bidang studi lain di sekolah mereka atau dalam kegiatan MGMP masing masing kelompok guru bidang studi. Metode pendekatan yang ditawarkan pada kegiatan PKM ini adalah pendampingan penuh dengan tahapan: 1) Pertemuan awal kepada guru mitra dalam kegiatan penyamaan persepsi tentang pentingnya IT dalam pembelajaran dan evaluasi pembelajaran, 2) Pelatihan intensif mengembangkan soal pr/kuis/ujian dan aplikasi soal kuis/ujian daring/online pada media kuis interaktif online quizizz, 3) FGD terkait media kuis interaktif online quizizz yang dikembangkan dalam pelaksanaan pr/kuis/ujian siswa, 4) Simulasi/praktek uji coba langsung dan 5) evaluasi hasil kegiatan.
