Abstract

The presence of water hyacinth in waters can be a threat to aquatic ecosystems. Its naturally fast growth and excess nutrients in the waters cause its growth to become uncontrollable. So it is necessary to handle the biomass and produce it. One thing that can be done is to turn it into organic fertilizer. The problem is, water hyacinth is a lead (Pb) hyperaccumulator plant. So that the biomass produced by water hyacinth contains a large amount of Pb. This study aims to see the effect of vermicomposting on the amount of Pb contained in water hyacinth biomass. The research began by converting water hyacinth biomass into a living medium for earthworms. Changes in Pb levels were observed before and after the earthworms were added. The results found a change with an average initial content of 2.7857 ppm to 2.0477 ppm. So from this study, it was found that the decrease in Pb levels was 26.4924% Keywords: waterhyacinth, hyperaccumulator,biomass, earthworm, vermicomposting.

Abstract

Wuluh star fruit is a plant that is rich in benefits. The population of this plant is very abundant in the community both in the yard or as a shade plant in the yard. The population of this plant is not proportional to its utilization so that the star fruit usually falls and rots. Seeing this, a community service activity was carried out regarding the use of starfruit into dish soap, which besides being able to add to the economic value of starfruit, can also reduce environmental pollution. Wuluh star fruit (Averrhoa bilimbi L.) contains saponins, flavonoids, acetic acid, and vitamin C. Saponins have the ability to kill bacteria while flavonoids can destroy bacterial proteins by lysis method so that bacteria cannot reproduce and die. Saponins also function as a foam producer so that they can be used in the manufacture of dish soap. Keywords: Wuluh star fruit, saponin, dish soap
