The problem of plastic waste in Indonesia is increasingly worrying due to its long degradation duration. Bioplastics made from starch are easily degradable nature and have a lower contribution environmental pollution. This study aimed determine the effect ZnO glycerol additions on thickness, tensile strength, elongation, Young’s Modulus, water absorption, biodegradation bioplastics. results ind...

Edible film is a packaging development for environmentally friendly food that composed of organic ingredients, so it safe consumption. Natural polymers make up edible films include polysaccharides, lipids, and proteins to replace synthetic materials. The characteristics good have properties like other plastic packaging, namely being easy shape, transparent, flexible, not easily damaged, cheap. ...

Nearly forty years ago R. L. Berg proposed that plants with specialized pollination ecology evolve genetic and developmental systems that decouple floral morphology from phenotypic variation in vegetative traits. These species evolve separate floral and vegetative trait clusters, or as she termed them, "correlation pleiades." The predictions of this hypothesis have been generally supported, but...
