Â
Sampah anorganik yang banyak ditemukan salah satunya adalah plastik. Sampah plastik tersebut secara alami dapat terdegradasi di lingkungan oleh mikroorganisme seperti bakteri. Tujuan dalam penelitian ini adalah Mengetahui hasil penapisan bakteri pendegradasi plastik LDPE pada tanah TPA Tambakrigadung dan persentasi massa plastik yang terdegradasi oleh bakteri. Proses penapisan bakteri dilakukan dengan metode streak plate pada media NA, sedangakan proses biodegradasi menggunakan campuran tanah TPA dengan tambahan media MSM yang dimodifikasi. Hasil penapisan bakteri didapatkan tiga koloni. Persentase penurunan massa plastik pada uji A sebesar 7,86%, sedangkan pada uji B sebesar 13,16%. Hal tersebut dikarenakan komposisi pada suspensi media lebih banyak sehingga akan memberikan kesempatan pada bakteri dalam memanfaatkan komponen plastik.
