Abstract

Volume timbulan sampah anorganik dari aktivitas manusia mengalami peningkatan signifikan hingga 30-40%. Berbagai upaya yang dilakukan diantaranya tetap memberikan dampak negatif bagi lingkungan. Salah satu upaya alternatif penanganan sampah plastik saat adalah biodegradasi melalui pemanfaatan serangga Tenebrio molitor. Penelitian ini bertujuan untuk mengetahui kemampuan degradasi larva Tenebrio molitor pada sampah PS dan PVC melalui berat larva, survival rate dan laju degradasi sampah. Metode penelitian yang digunakan adalah eksperimen dengan beberapa jenis perlakuan sampah plastik sebagai pakan tunggal dan pakan gabungan. Eksperimen dilakukan selama 14 hari dengan 17 total sampel, terdiri dari 10 gr sampel dan 10 ekor larva per sampel. Penelitian menunjukkan terjadinya penambahan berat larva pada hampir semua perlakuan. Berat larva rata-rata meningkat sebesar 0.15 gr dari 0.70+0.07 ke 0.84+0.19. Berat larva tertinggi pada sampel pakan gabungan PS+PVC+kontrol (1.10+0.10). Uji t-berpasangan sebesar 0.002<0.05. Survival rate larva menunjukkan nilai positif dengan median terendah pada PVC 10 (9-10). Tingkat degradasi tertinggi pada PS+PVC+kontrol (0.08 gr) dengan WRI 0.57%. Nilai pearson korelasi antara laju degradasi dengan berat larva dan survival rate masing-masing sebesar 0.851 (p-value 0.068>0.05) dan 0.332 (p-value 0.585>0.05) Kemampuan degradasi sampah plastik menggunakan larva Tenebrio molitor yang paling baik adalah pada perlakuan PS+PVC+kontrol.
