Most of society depends on the use of plastic as packaging material. The material most commonly used as a constituent of plastics comes from PET (Polyethylene terephthalate). Dependence on PET-based plastics causes a high increase in landfills due to non-degradability materials. PET can be degraded by physicals and chemicals method, but those methods raise the problem of secondary environmental…

Much of Indonesia's organic waste is poorly utilized. Bioconversion using Hermetia illucens is an effort that can be made to reduce organic waste by 56%. The bionebulization ability of the black army fly (Hermetia illucens) depends largely on the density of the larvae, the quality and quantity of waste that is used as the source of its feed. A higher density of the larvae than that of the densi…
Open-pit coal mining will encourage the oxidation of sulfide minerals, releasing sulfuric acid, which will drastically lower the pH. This occurrence is known as acid mine drainage. Acid Mine Drainage (AMD) has a low pH value and can easily dissolve heavy metals in water, such as Zn and Cr. Control of acid mine drainage needs to be done either during or after the mining process ends. Acid mine d…
