Abstract

Pembelajaran IPA terpadu dapat meningkatkan efisiensi dan efektivitas pembelajaran. Selain itu pemanfaatan media pembelajaran juga belum maksimal. Berdasarkan hasil observasi di SMPN 7 pati dan wawancara dengan guru IPA diperoleh hasil, bahwa di SMPN 7 Pati sudah menggunakan Kurikulum 2013,  dalam hal sarana prasarana sudah cukup baik contohnya dibeberapa kelas sudah terdapat LCD proyektor untuk menunjang proses pembelajaran. Namun kenyataan dalam lapangan, guru  belum memanfaatkan sarana dan prasarana tersebut dan lebih banyak menggunakan buku teks atau panduan IPA daripada menggunakan media. Hal ini menyebabkan siswa merasa kesulitan untuk memahami materi IPA yang bersifat abstrak. Media pembelajaran yang dikembangkan berupa media audio visual yang berpendekatan saintifik. Media audio visual yang berpendekatan saintifik dikembangkan bertujuan untuk mengetahui kelayakan media dan efektifitas penggunaan media dalam proses belajar. Metode yang digunakan didalam penelitian ini adalah Research and Development (R&D). Produk yang telah dikembangkan selanjutnya divalidasi oleh pakar kemudian dilakukan uji coba skala kecil dan uji coba skala besar. Data yang dianalisis dalam penelitian ini adalah data validasi produk oleh pakar, angket tanggapan siswa, angket tanggapan guru dan hasil belajar siswa. Berdasarkan hasil validasi media oleh pakar memperoleh 92% dan validasi materi oleh pakar memperoleh 90%.  Hasil tanggapan siswa dan guru terhadap media audio visual menyatakan sangat layak. Hasil belajar siswa melalui tes memperoleh rerata nilai pretest 54,5 dan rerata nilai postest 78,0. Hasil pretest-postest kemudian dianalisis dengan uji Gain dan memperoleh skor 0,50 dengan kriteria sedang. Sesuai dengan hasil penelitian maka disimpulkan bahwa media audio visual sistem sirkulasi darah yang berpendekatan saintifik layak dan efektif digunakan dalam proses pembelajaran. Integrated science teaching can improve the effectiveness of learning. In addition, the use of instructional media is also not used optimally. Based on the observation in SMP 7 Pati and interview with the science teachers, it can be showed that the school has already used 2013 curriculum, and the media is also well prepared by the school because the school has provided LCD projector in every class. However, the reality showed that, the teachers had not used the facilities and prefer to use more textbooks or science books rather than using the media. Thus, the students felt difficult to understand abstract science material. Learning media developed in this research was audio visual media based on scientific approach. The purpose of this research was to determine the feasibility and effectiveness of media in the learning activity. The method used in this research was Research and Development (R & D). The products were developed, and then validated by experts and afterwards tested in small and large-scale trials. The data analyzed in this study were product validation by experts, students interview sheets, teachers interview sheets, and students learning achievement. The result of the media validation by experts was  92%. Meanwhile, the material validation was 90%. The results of students and teachers interview sheets to audio visual media resulted in very feasible criteria. From the results of students learning tests, mean value of 54.5 could be obtained in pretest. Meanwhile, 78.0 mean value was obtained in post test. Then, the pretest and post test results were analyzed with gain test, that resulted in a score of 0.50, which was a decent value.
