Abstract

Grapes are perishable fruits susceptible to damage during transportation and storage post-harvesting, due to moisture loss, microbial contamination, oxidative damage, and physical degradation. These problems lead to weight loss, reduced shelf life, and deterioration of appearance, which can be overcome by using edible coating for preserving post-harvest fruits due to simplicity, non-toxicity, and cost-effectiveness. Starch is an excellent material for edible coating, with cassava peel serving as a suitable source because of good film-forming ability, biodegradability, and non-toxicity. Cassava peel starch also has the capacity to form a semi-permeable barrier that can reduce moisture and gas exchange for edible coating. However, starch is less resistant to pathogenic microbes, showing the need to incorporate limonene essential oil (EO) extracted from sweet orange peel with good antibacterial properties. Therefore, this study aimed to determine the most effective formulation of cassava peel starch and sweet orange EO in edible coating. Analysis was also carried out to evaluate the effect of coating on the quality of grapes based on weight loss, pH, antibacterial properties, and fruit organoleptic. The experiment was conducted by coating grapes using dip method and analyzed during 7 days of storage. Starch was successfully extracted from cassava peel with a facile method to obtain yield of 52.02%. The results showed that the most effective formulation of starch and EO in edible coating was 5% and 0.1%, respectively, indicating potential to significantly maintain the quality of grapes. The addition of orange peel-based EO also inhibited microbial growth during storage. At this formulation, grapes coated with EO-starch film showed an average weight loss of 5.94% and pH 4.21, with lower total microbes of 1.39x10 3 CFU/gram. This indicated that edible coating enriched limonene EO was effective in preserving grape quality and prolonging shelf life.

Abstract

Declining agricultural productivity in tropical and subtropical regions is largely due to high soil acidity, which inhibits nutrient availability and increases the solubility of toxic elements such as aluminum and iron. Acidic soil is one of the main constraints in agricultural systems, characterized by low soil pH and an imbalance of essential nutrients for plants. This study aimed to systematically review various approaches to acid soil amelioration, focusing on the mechanisms and materials used. The method used in this study was a Systematic Literature Review (SLR), through an analysis of 38 reputable scientific articles published between 2021 until 2025 and indexed in the Scopus database. The article selection process was based on inclusion criteria specifically related to the results of acidic soil amelioration research. The synthesis results show that acidic soil amelioration approaches could be grouped into several main categories, namely liming-based, biochar-based, biochar and organic-based, organic (non-biochar)-based, organomineral-based, and industrial waste-based. Although research on acid soil amelioration has developed rapidly, there was still considerable variation in the selection of materials, composition, and application methods used. Overall, this systematic literature review provides a structured overview of the mechanisms and materials used in acid soil amelioration.
