Abstract

This article reviewed the hematite α-Fe2O3, which focuses on its material properties, nanostructures, synthesis techniques, and its numerous applications. Researchers prepared the hematite nanostructure using the synthesis methods, such as hydrothermal, and, further, enhanced it by improving the techniques to accommodate the best performance for specific applications and to explore new applications of hematite in humidity sensing.

Abstract

The corn food commodity is one of the leading commodities of West Nusa Tenggara. In addition, NTB is also one of the target areas for increasing national maize production. This study aims to determine the yield yield of several varieties of maize given a mixed package of organic, inorganic and mycorrhizal fertilizers. This research was conducted from May to August 2020 in Midang Village, Gunung Sari District, West Lombok Regency, Microbiology Laboratory and Soil Physics and Chemistry Laboratory, Faculty of Agriculture, Mataram University. The method used in this study was a randomized block design with 5 treatments, namely V1 (P8IS variety), V2 (P8DPP variety), V3 (Gumarang variety), V4 (Lamuru variety), V5 (Sukmaraga variety). Each treatment was repeated 3 times in order to obtain 15 experimental plots. The results showed that maize varieties given organic, inorganic and mycorrhizal fertilizers had a significant effect on growth, yield of maize, nutrient status and nutrient uptake, number of mycorrhizal spores and root colonization by mycorrhizae. Sukmaraga variety has better growth and yield than other varieties, this is reflected in the growth parameter indicators and yield parameter indicators, namely harvest dry ear weight per plant (271.5 g), dry ear weight per plant (255 g), length ear (16.5 cm), ear diameter (5.3 cm), seed dry weight per plant (180 g), and weight 1000 seeds (288 g).

Abstract

Starch based biofoams have emerged as a sustainable alternative to conventional plastics, yet their performance varies significantly depending on formulation and processing methods. This study aims to comprehensively evaluate the relationship between raw material composition, production techniques, and functional properties of biofoams through an integrated analysis of ten recent formulations. The methodology involved a systematic review of experimental data derived from diverse production methods, including thermopressing, microbial fermentation, evaporative drying, freeze drying, and molding. Results reveal that banana peel and cassava starch and banana stem fiber biofoam offers an optimal balance of high tensile strength 43.86 MPa, low water absorption 16.91%, and moderate biodegradability 65.82%, making it ideal for dry food packaging. In contrast, bamboo powder biofoam exhibits exceptional water absorption 97.1%, suitable for horticultural substrates, while bamboo cellulose–starch composite demonstrates outstanding compressive strength 78.74 MPa and thermal stability 410.86 °C, indicating potential for lightweight structural applications. These findings underscore that biofoam design must be application-specific, providing evidence-based guidance for developing effective, sustainable materials tailored to real world needs.
