Abstract

Biopore Infiltration Hole is a small hole in the soil that is formed due to the activity of soil organisms such as worms, root movement in the soil, termites and other animals. The hole is filled with air until it enters the water stream. Rainwater does not go directly into the gutter but seeps into the ground through the hole. The benefits of the Biopori Infiltration Hole for the community are: Reducing the impact of floods, landfills for organic waste, fertilizing plants, and improving ground water quality. The expected results from the implementation of this activity are to reduce the impact of flooding in the Malasilen Village area and increase the understanding of residents to recognize the surrounding environment, increase the spirit of community cooperation to overcome problems in their environment, and prevent disease outbreaks due to puddles of drainage water.

Abstract

The extraction of active substances from ant nests can be affected by various extraction methods, whether conventional or sonication. Sample extraction was carried out by maceration and ultrasonic methods with the use of solvents to yield flavonoid compounds. The solvents used were aquadest, 70% ethanol and n-hexane, with a material-to-solvent ratio of 1:50 (w/v). The highest flavonoid content of 14% was obtained by ultrasonic-assisted extraction method, with aquadest as the solvent and at operating conditions of 24 minutes at a temperature of 40oC. Due to their high aquadest solubility and the presence of one or more sulphate ions that are bound to the hydroxyl phenol or sugar, the flavonoids produced are classified as flavonoid sulphate.

Abstract

Red fruit (pandanus conoideus) is one of the natural biological resources that contains lipid compounds that are beneficial and important for health. However, the content of red fruit oil components is sensitive to oxygen, light, and heat, so it impacts damage to the content and a relatively short shelf life. The emulsification method can increase the benefits and shelf life of red fruit oil. Emulsions can be stored by preserving active substances in their core and protecting them with a shell layer. Adding alginate to the water phase can increase the stability of the emulsion against aggregation because these molecules can cause steric and electrostatic repulsion between droplet interfaces. This study aims to synthesize red fruit oil emulsions with alginate as a co-surfactant. The variables observed were the ratio of ingredients, the effect of speed, and the time of emulsification stirring. The study's results, namely alginate, can be used as a co-surfactant in the synthesis of red fruit oil emulsions. The ratio of red fruit oil emulsion ingredients is 1% weight/volume, tween 80 1% weight/volume, and alginate 2% weight/volume of a total volume of 40 ml. The emulsification process conditions were carried out at room temperature with a stirring speed of 25,000 rpm and a stirring time of 10 minutes. The resulting emulsion is an oil-in-water emulsion (m/a). The emulsion is dominated by hydrophilic or polar components caused by tween 80 surfactants and alginate co-surfactants. In addition, the creaming formation time occurred after 216 hours, and the separation time occurred after storage for 552 hours.
