ABSTRACT Red grapes are fruits that contain relatively high water content and have a soft texture, which makes them highly susceptible to damage and spoilage. Postharvest handling efforts are necessary to prevent early damage and extend the shelf life of red grapes through the application of an edible coating derived from chitosan. Chitosan is suitable as an edible coating because it meets…
ABSTRACT Bioplastics are eco-friendly alternatives to petrochemical plastics, capable of degrading naturally. Starch-based bioplastics, such as those from sago are renewable but limited by brittleness and moisture sensitivity. To enhance their performance, cellulose fillers are often incorporated. Sago pulp, a lignocelluloserich byproduct of sago starch processing, offers promising potenti…
ABSTRACT Sago is one of the plants with high starch content and potentially to be used for biodegradable film production. Biodegradable film from natural sago starch has low mechanical properties and water resistance so it is necessary to modify the starch with sodium tripolyphosphate as cross-linking agents. Biodegradable film from modified sago starch still has low mechanical properties,…
ABSTRACT Cocoa pod husk waste has the potential to be utilized in an economically and environmentally friendly manner, one of which is as a raw material for the production of activated charcoal. Activated charcoal is a solid form of carbon with a large surface area, ranging from 100 to 2000 m²/g. The objective of this study was to identify the most effective concentration of sulfuric acid as …
ABSTRACT This study aimed to obtain the best extraction temperature and pH for the pectin characteristics of pineapple peel in accordance with the quality standards of the International Pectin Producers Association (IPPA).

ABSTRACT Liquid body wash is a personal care product formulated to cleanse the skin. The addition of natural extracts, such as pineapple peel extract, in the formulation of liquid bath soap is expected to enhance its characteristics, making it safe and suitable for use. This study aimed to determine the best treatment for liquid soap with added pineapple peel extract on the antioxidant activit…
ABSTRACT Sweet orange is one of the horticultural commodities that is perishable due to its highwater content and continuous respiration and transpiration process after harvest. This condition causes sweet oranges to deteriorate quickly. One effort to reduce fruit damage is by applying an edible coating made from cassava starch. The purpose of this study was to obtain the best concentratio…
ABSTRACT Biodegradable plastic is a type of eco-friendly plastic that can decompose naturally because it was made from organic raw materials such as starch. Starch sources can be obtained by utilizing agricultural waste such as jackfruit seeds. Biodegradable plastics made from starch have low mechanical properties so there is a need for the addition of reinforcers or fillers such as cellul…
ABSTRACT Jengkol fruit peel are plantation waste that can be used as raw materials for activated charcoal. Activated charcoal is made by carbonization and activation processes. This research aimeds to obtain the best concentration of Natrium Hydroxide as an activator in making activated charcoal from jengkol fruit peel. The research was conducted experimentally used a completely randomized…
ABSTRACT Banana is a climacteric fruit that continues to respire after harvest, making it susceptible to damage during storage. This study aimed to determine the most effective concentration of red galangal extract in a corn starch-based edible coating to extend the shelf life of barangan bananas. The research used a non-factorial Completely Randomized Design (CRD) with six treatments and …
ABSTRACT The purpose of this research was to get the optimal immersion time of edible coating made from cassava peel starch on the quality of crystal guava during storage. This research used a completely randomized design with six treatments and three replications, resulting in 18 experimental units. The treatment in this study was the duration of dyeing edible coating of cassava peel star…
ABSTRACT This study aims to obtain selected characteristics of activated charcoal made from palm fiber with the help of phosphoric acid as an activator.
