Abstract

The increasing environmental concerns associated with synthetic plastics have driven the search for biodegradable alternatives. This study investigates using sweet corn cob waste (Zea mays L. saccharata) for bioplastic production with varying concentrations of zinc oxide (ZnO) and glycerol as additives. The objective is to evaluate the influence of these additives on the mechanical properties, functional group composition, and biodegradability of the resulting bioplastics. The experimental procedures involved the delignification of corn cobs, bioplastic synthesis, and subsequent characterization through Fourier Transform Infrared Spectroscopy (FTIR), tensile strength and elongation tests, and biodegradability assessments. The results showed that increasing ZnO concentrations improved tensile strength, with the highest recorded at 9% ZnO and 25% glycerol. However, increased ZnO reduced elongation and biodegradability due to increased material stiffness. Conversely, higher glycerol concentrations enhanced flexibility and biodegradability but decreased tensile strength. The optimal formulation was identified at 3% ZnO and 35% glycerol, which provided a balanced combination of mechanical strength and biodegradability. This study demonstrates the potential of sweet corn cob waste as a sustainable raw material for bioplastics, contributing to environmentally friendly alternatives to conventional plastics.

Abstract

The dairy industry is among the most energy-intensive sectors within the food processing chain, relying heavily on fossil fuels for heating, cooling, and packaging operations. In response to global sustainability challenges and climate targets, this review explores integrated strategies for energy transformation in the dairy sector, focusing on renewable energy adoption, waste valorization, and digital technologies. Emphasis is placed on the use of soybean hulls—a rich source of lignocellulosic biomass—as feedstock for bioethanol production through a sequence of pretreatment, hydrolysis, fermentation, and distillation processes. Additionally, the role of biogas and solar energy integration, along with energy recovery systems and IoT-based monitoring, is analyzed for improving operational efficiency. The findings reveal that such transformations can reduce greenhouse gas emissions, lower operational costs, and increase energy self-sufficiency, especially when supported by circular economy principles. This review highlights the potential for scaling these solutions in both industrial and small-scale dairy production, offering practical insights into how renewable energy and digital innovation can drive a more competitive, sustainable, and decarbonized dairy industry.

Abstract

The most common problem encountered in the use of well water is the presence of metal contaminants, particularly iron (Fe) and manganese (Mn). One alternative solution is the use of filtration with zeolite and activated carbon. This research aims to improve the quality of well water by reducing Fe, Mn, and turbidity levels using filtration technology. The treatment reactor consists of two reactors with the difference between reactors 1 and 2 lies in the type of media used. Reactor 1 uses zeolite media, and reactor 2 uses activated carbon. The filtration column used is a PVC pipe with a diameter of 10 cm and a length of 1 m. The independent variable in this study is the composition of the filtration media, consisting of a combination of quartz sand-zeolite and quartz sand-activated carbon. The research findings show that in reactor 1, the decrease in Fe levels from the first day to the third day is 0.4975 mg/L, 0.6175 mg/L, and 0.605 mg/L, whereas in reactor 2, it is 0.9175 mg/L, 0.7725 mg/L, and 0.685 mg/L. The decrease in Mn levels in reactor 1 over three consecutive days is 0.08 mg/L, 0.07 mg/L, and 0.05 mg/L, while in reactor 2, it is 0.12 mg/L, 0.09 mg/L, and 0.06 mg/L. The decrease in turbidity levels in reactor 1 consecutively is 20.825 NTU, 13.305 NTU, and 11.09 NTU, while in reactor 2, it is 21.4775 NTU, 18.36 NTU, and 12.23 NTU. These filtration results have met the clean water quality standards according to PERMENKES No. 32 of 2017.
