DEGRADATION OF SOME POLYSTRENE USING BEETLE LARVAE (TENEBRIO MOLITOR L.)

One alternative to waste processing polystyrene is use Tenebrio molitor larvae. This study aims determine the increase in body length and weight, rate of degradation, value Waste Reduction Index (WRI) larvae T. molitor. used laboratory experimental using completely randomized design model (CRD) data analysis with control 4 feed treatments. Each treatment level was repeated 5 times order obtain 25 units. Larvae were reared a plastic container containing 10 given bran for polystrene treatment, each as much 1 gram. The food packaging, walls, electronic ice boxes. measured weight every 3 days 30 days. Parameters observed larvae, degradation WRI values.The highest mean larval on wall 1.69 cm. lowest packaging (1.59 cm). average gain has uniform 0.07 gr. values at 0.019 0.63%. while 0.11 0.37%.
