Unstable harvest prices tend to make people disappointed because it is not uncommon to meet prices that do not match expectations. Therefore, the public must be smart in anticipating unsatisfactory crops one of them by treating crop waste to be utilized to be additional income. Corn waste, for example, can be used as a medium for making mushroom janggel. Corn is usually sold after going through the milling process until the seeds of corn are separated from the cobs. After that corncobs or commonly called janggel used as fuel for cooking traditionally and just thrown away without any use. Therefore, the purpose of this dedication is to provide training to the public in order to obtain value-added income through the utilization of corncob as a medium for making mushroom janggel. The results obtained indicate a considerable increase of sales of mushrooms jejel with perkilogram prices reached 35 thousand to 40 thousand dollars. For marketing is still limited to traditional markets.

The type of experiment in this study was quasi experimental research (quasi alphabets experiment) and experimental design that used up was one-Group Pretest-Posttest-. The population in this research was the whole grade VIII of SMPMuhammadiyah 1 Yogyakarta, which was grade VIII-D as sample. The independent variable in this study was a model of Quantum Learning Teaching and the dependent variable in this study was the studentmotivation mathematic’slearning. The instrument used was the student learning motivation questionnaire. To test the effectiveness of Quantum Learning Teaching model, the data were analyzed by using one sample t-test. The results showed that the model of Quantum Learning Teaching effective motivational aspects of learning math.

Penelitian ini merupakan penelitian pengembangan menggunakan model pengembangan 4-D yang terdiri atas 4 tahap yaitu (1) pendefinisian, (2) perancangan, (3) pengembangan, dan (4) penyebaran. Subjek uji coba penelitian yaitu 49 siswa kelas VIII SMP Negeri 2 Seputih Surabaya, Kabupaten Lampung Tengah, Lampung, terdiri dari 12 siswa pada uji coba terbatas dan 37 siswa pada uji coba lapangan serta seorang guru matematika. Instrumen yang digunakan untuk mengukur kevalidan perangkat pembelajaran yang dikembangkan adalah lembar validasi. Instrumen untuk mengukur kepraktisan perangkat pembelajaran adalah lembar penilaian guru, lembar penilaian siswa, dan lembar observasi keterlaksanaan pembelajaran. Instrumen untuk mengukur keefektifan perangkat pembelajaran yaitu tes ketercapaian kompetensi dasar (TKKD), tes kemampuan koneksi matematis (TKKM), dan angket minat terhadap matematika. Analisis data dilakukan dengan cara mengkonversi data kuantitatif berupa skor hasil penilaian menjadi data kualitatif berupa nilai standar skala lima. Penelitian ini menghasilkan perangkat pembelajaran berbasis Pendidikan Matematika Realistik yang terdiri dari silabus, rencana pelaksanaan pembelajaran (RPP), lembar kegiatan siswa (LKS), TKKD, dan TKKM. Produk yang dihasilkan memenuhi kriteria valid, praktis, dan efektif. Kevalidan terlihat dari hasil penilaian ahli yang menyatakan perangkat pembelajaran valid, dengan kategori sangat baik. Kepraktisan terlihat dari hasil penilaian guru yang menyatakan bahwa perangkat pembelajaran praktis, dengan kategori sangat baik, penilaian siswa dengan kategori baik, dan keterlaksanaan pembelajaran yang mencapai 84,90%. Keefektifan terlihat dari tercapainya minimal 80% siswa lulus KKM ditinjau dari ketercapaian kompetensi dasar dan kemampuan koneksi matematis, serta lebih dari 80% siswa mempunyai minat terhadap matematika dalam kategori minimal bai

In the 21st century learning focuses on the process of skills in applying materials using technology, and collaborating. Mathematics learning is learning that requires students to not only memorize and read but also be directly involved in the process of finding concepts. Learning media is an alternative to creating interactive and fun learning. In this study the research design adaptation of the multimedia development research model: Decide, Design, Development and Evaluation (DDD-E). The results of this study are in the form of conceptual and procedural models of steps in developing game-based learning for mathematics subjects using the DDD-E model design.
