 Agricultural waste is often underutilized, despite its significant potential as a raw material for environmentally friendly products. This study aims to develop bioplastics from corn waste by utilizing locally sourced enzymatic technology as the main catalyst in the biomass conversion process. Corn waste in the form of cobs and post-shelling residues was first prepared through drying, grinding, and mild chemical pretreatment to loosen the lignocellulosic structure. Subsequently, enzymatic hydrolysis was carried out using local enzymes derived from indigenous microorganisms, which decomposed cellulose and hemicellulose into monomeric sugars. The hydrolyzed sugars were then fermented into natural polymers, molded using the solution casting method, and dried to form bioplastic sheets. The results revealed that the produced bioplastics possessed mechanical properties comparable to commercial PLA, with tensile strength of 45–50 MPa, an elastic modulus of 2.5 GPa, and elongation at break of 5–7. Biodegradability testing showed that the material degraded up to ±85 within 90 days, exceeding the minimum threshold of 80% considered satisfactory. These findings confirm that corn waste can be transformed into competitive and eco-friendly bioplastics, while also highlighting the potential of locally based enzymatic technology for industrial-scale applications. The implications of this research extend not only to reducing waste and plastic pollution but also to strengthening the circular economy through the utilization of renewable agricultural resources.

The development of Solar Photovoltaic Power Plants (SPPVs) as Renewable Energy in Indonesia is increasingly growing. However, SPPVs have a relatively short lifespan, necessitating the proper management of their waste, particularly solar panels. This research aims are, firstly, to analyse the regulations governing the parties responsible for managing waste from SPPVs that have reached the end of their lifespan. And, secondly, to compare waste management regulations for solar panels implemented in Europe and America as best practices for handling end-of-life SPPV waste. This research employs a normative juridical and comparative-descriptive research method, comparing regulations and implementation of SPPV waste management in Indonesia and other countries. The Finding of this research are in line with Law No. 32 of 2009 on Environmental Protection and Management and Government Regulation No. 22 of 2021, which states that any person or business entity generating waste is obligated to handle and restore it, in practice, the Power Purchase Agreement stipulates that waste management of SPPVs is the responsibility of the winning Project Company (in this case, the Consortium). And, in Europe and several US states have issued regulations for managing waste from end-of-life SPPVs. These regulations require solar panel manufacturers to have a recycling program for their own products after their end-of-life. However, managing end-of-life solar panel waste is a complex issue that requires cooperation from various stakeholders, including the government, project companies, and solar panel manufacturers. Adopting waste management policies from Europe and America is recommended to ensure that SPPV waste management is conducted responsibly and environmentally friendly.    

The aim of this literature study is to conclude that the use of fly ash as a replacement material for most of the functions of cement in concrete mixes meets the standards for using concrete mixes as environmentally friendly building construction materials in the context of sustainable development, reducing the risk of the greenhouse effect caused by carbon dioxide. The conclusion is that Fly ash, as waste from burning coal for power plants, can be used as a substitute for most of the functions of Portland cement, so that the waste material becomes an economic value and an effort to save the environment. And the mechanism for using HVFA-SCC concrete provides a work productivity solution in the construction sector in reducing the use of labor more efficiently and economically, as well as reducing the use of a large proportion of cement in the concrete composition. Fly ash contains physical and chemical elements with an equivalent composition that is similar to Portland cement. The softness of the fly ash grains is beneficial for filling empty spaces, making the concrete denser and more compact. The equivalent physical and chemical properties mean that fly ash can replace Portland cement.

In the midst of rapid industrial progress and global economic growth, the use of plastic has increased dramatically, causing serious environmental problems due to the accumulation of plastic waste. One of the most worrying aspects of this problem is the presence of microplastics, namely plastic particles less than five millimeters in size. The more accumulation of plastic waste found in the waters will cause damage to the surrounding water and sea environment, plastic waste that is not collected will be exposed to sunlight and exposure to air, the longer it will decompose into small particles called microplastics. In this research, the author researched using the library research method, namely by collecting and studying existing literature from various sources such as: journals, articles, books and others related to this research. Microplastics have spread widely in the environment, from oceans to land, and have had a serious impact on organisms and ecosystems throughout the world. The process by which microplastics are formed, their distribution in the environment, their impact on aquatic and terrestrial organisms, and their potential impact on human health are the main focus research and public attention. To overcome the microplastic problem, a holistic approach is needed that involves collaboration across sectors and scientific disciplines. Handling and mitigation efforts must cover various aspects, starting from regulating the use of single-use plastics, more effective management of plastic waste, developing technology for detecting and eliminating microplastics, to educating the public about the dangers of microplastics and the importance of environmentally friendly behavior. Concrete steps such as banning the use of single-use plastics, promoting recycling, innovation in product design, and cross-border cooperation in managing plastic waste are key in efforts to reduce the negative impact of microplastics. Only by taking these steps together can we create a cleaner, healthier and more sustainable environment for future generations.
