Indonesian  Anti Trash Day this year was  celebrated by the  government with the launching of the  Paid Plastic Bags program, aimed at  reducing   plastic waste in Indonesia which has increasingly become out of control.  Stacks of plastic waste on the ground can impede the flow of water in the soil so as to trigger flooding. While the solution to reduce plastic waste through recycle seems  to be less effective. Combustion to reduce plastic waste will pollute the air. Out of  concerns over the effects  of plastic bags  which  is increasing from time to time, five students of Gadjah Mada University (UGM): Fajar Bayu Prakoso, Andika Cahya Widyananda, Annisa Fakhriyah Rofi, Dyah Ayu Permatasari, and  Aditya created Bioplast of durian fruit seeds. Fajar Bayu Prakoso as head of the team said, plastic made from materials that are difficult to decompose (non-degradable) will cause environmental problems. It takes quite a long time, between 50-100 years,  to break down. Durian seed was chosen as the  basic material  for the manufacture of plastic bags, because it has fairly high starch content,  nearly 50 percent of its weight. Higher than cassava which  is around 20 percent. While starch act as filler in the mixture so that the bioplast  plastic  has  high-density and  tensile strength. Utilization of durian seeds as bioplastic materials can  also suppress durian seed waste. Until now  the waste of  durian seeds are  just thrown away. According to Fajar, he and his friends has  started a research on durian seeds  bioplastics since mid-2014 under the guidance of a lecturer in the Department of Chemical Engineering, Faculty of Engineering Prof. Rochmadi.

The first step in the manufacture of bioplastics is to pound  durian seeds into flour. Then  soaked it in lime water for 2-3 days to remove the sap from  the seeds,  then dry them  under the sun for a day. Once dry, the hard  durian seeds are separated from the brownish white starch on the inside and turn  it   into  flour using a  grinder. The flour is then dried in the oven for about 30 minutes to remove water content.  In the study, the five students  used a sample with a weight of 50 grams which  can make  as much as  3-4 bioplastic sheet sheets with the  size of 13x13 cm each . The plastic was  implanted in the soil or compost media and was  biodegraded within two months. Even so, further research is needed to know in detail how much time is needed for the decomposition of this bioplastic.  These  students are optimistic the  decomposition of their creations will be much faster because in the two months  time there were already  indications of decomposition process.  The team is hoping, this durian seeds bioplastic can be mass produced after further research. So that  the iproblem  of plastic waste is no longer plaguing  people and  the environment  can be well maintained ..
