The problem of plastic waste has developed into an urgent global environmental crisis, due to the nature of plastic that is difficult to decompose and can persist in the environment for hundreds of years. This study explores pyrolysis as a promising oxygen-free thermal conversion technology to overcome plastic waste by converting it into valuable products such as oil, gas, and char. The main focus of the study is the use of zeolite catalysts in the pyrolysis of polyethylene plastic waste from household waste, with a total mass of 1.5 kg of plastic waste and 200 grams of zeolite catalyst. The catalyst used, natural zeolite from Klaten, Central Java, was heated at a temperature of ±200°C before being used in a pyrolysis reactor at an operating temperature of 450°C for ±4 hours. The results showed that the use of zeolite catalysts reduced the percentage of liquid and solid products, but increased the percentage of gas products. In addition, the use of catalysts tended to reduce the content of medium fractions (C11-C22) and paraffin fractions, while increasing the light fractions (C4-C11) and olefin fractions. These findings indicate the potential of pyrolysis as a sustainable solution to the plastic waste problem with positive impacts on the environment and economy.

Clay soil stabilization is a crucial process to enhance the soil's bearing capacity and stability, making it more suitable for construction purposes. Stabilizing clay soils improves their mechanical properties, reduces swelling, and increases their load-bearing capacity, which is essential for the foundation of various structures. This study aims to investigate the effect of lime (CaO) addition and curing time on the physical properties of clay soil, particularly focusing on unconfined compressive strength (qu) and overall soil stability. The experimental methodology involved applying different percentages of lime content (ranging from 3% to 7%) and varying curing times (7, 14, and 28 days). The soil samples were tested for their unconfined compressive strength after each combination of lime content and curing duration. The results indicated that the addition of 5% lime (CaO) and curing for 14 days led to a significant improvement in the unconfined compressive strength by 153.3%, compared to the untreated clay soil. Furthermore, increasing the curing time beyond 14 days did not show substantial improvements in strength, suggesting that 14 days is the optimal curing period for this combination. The study also highlighted that the lime treatment not only enhanced the mechanical properties but also reduced the plasticity of the clay, making it more stable and easier to handle during construction. Based on these findings, it can be concluded that the appropriate combination of lime content and curing time plays a significant role in improving the stability of clay soils. This research provides valuable insights into optimizing soil stabilization techniques, offering an effective solution for enhancing soil properties for engineering applications

Petrochemical-based synthetic plastics pose significant environmental concerns due to their non-biodegradable nature. Bioplastics, particularly those derived from corn starch, offer a promising alternative because of their biodegradability and renewable origin. This article presents a narrative review analyzing the effects of various additives on the characteristics of corn starch-based bioplastics, including tensile strength, water absorption, and biodegradability. The review focuses on scientific publications from 2015 to 2025.  Three types of additives were examined: cellulose fibers, graphene oxide (GO), and polyvinyl alcohol (PVA). The results show that the combination of starch and PVA with glycerol yields the best overall performance, achieving the highest tensile strength (1.8 MPa), moderate water resistance 60%, and rapid biodegradation within 6–10 days. While cellulose improves mechanical properties, it tends to slow down the degradation rate. GO provides only slight enhancements in mechanical and water-resistant properties. Overall, the starch–PVA blend appears to be the most promising formulation for developing eco-friendly and applicable bioplastics in the future.
