AbstrakMeningkatnya penggunaan plastik diikuti dengan besarnya kepedulian terhadap isu lingkungan mengenai pembuangan produk plastik sintetis yang sulit terurai. Salah satu alternatif untuk mengatasinya adalah dengan memodifikasi plastik agar bersifat biodegradabel. Plastik biodegradabel (plastik ramah lingkungan) dirancang mampu terdekomposisi di alam. Tingkat di biodegradasi yang terjadi tergantung pada kondisi tanah seperti suhu, kadar air, tingkat aerasi, keasaman dan konsentrasi mikroorganisme sendiri. Berdasarkan hal diatas, maka dilakukan penelitian dengan tujuan mengetahui efektifitas penguraian plastik ramah lingkungan dengan metode pengomposan dalam tanah gambut (TG) dan tanah sampah, serta faktor pH. Dari hasil penelitian kami mendapatkan bahwa pada semua perlakuan uji pada hari ke-20 sampai hari ke-60 terjadi peningkatan persentase penurunan berat plastik ecoplas dan oxium. Sedangkan persentase perubahan berat plastik terbesar dari proses biodegradasi terhadap semua perlakuan uji adalah pada TG3pada hari ke-60 yaitu 0,45%. Secara umum, jika pH tanah dibuat semakin asam, maka menyebabkan penguraian plastik semakin bertambah.Kata Kunci : Plastik, Mikroorganisme tanah, lahan gambut.

Implementation of the 2013 curriculum in the implementation of learning, teachers have run the 2013 curriculum although sometimes do not adjust to the syllabus and RPP. Obstacles that occur is the method of learning approaches such as PBL, PBL is still difficult to implement because students have less literature and experience. Efforts are made teachers do various methods approach to create an active learning atmosphere and not saturate for learners, so they are more active in digging information. Implementation of the 2013 curriculum in the evaluation system, evaluation techniques used are formative and summative tests. The hindrance that occurs is that psychomotor assessment is rather difficult to do because there is rarely any practice in KBM. Efforts are made teachers classify learners in learning activities, assisted by individual assessments between friends, collaboration assessment with other teachers and the addition of tasks.
