| Summary: | The strength of a material is one option used to
determine the use of forms. The use of plastics on product
packaging is an efficient choice because plastics is light, practical
and easy to forms. This study is done to measure the plastic waste
hardness of mixed HDPE and PET type with teak tree sawdust
which melted into two portions by the amount of 18 gram. This
study finds the highest hardness index was achieved by the
mixture of 1.5 gram of sawdust, 5 gram PET and 11.5 gram
HDPE with the hardnesss point of 131. 3 N/mm under the 5000
gram pressure and temperature of 100°C while the lowest point of
86.6 N/mm by the mixture of 1 gram sawdust, 625 gram PET and
10.7 gram HDPE under the 5000 gram pressure and temperature
of 100°C. It can be seen that the lower the temperature of the
mixture compositions, the better the hardness because the
mixture is merged and binded better. |
