Abstract
The usage of Hordeum vulgare or barley straw as an algistatic to control eutrophication in lake has been applied in the United States and England. Inspired by barley straw, this research studied about Coix lachryma-jobi as a substitute for barley straw in Indonesia. The aim of this research is to determine the applicability of Coix lachryma-jobi product in reducing algal growth along with its interactions with the nutrients in the water. Two stages of experiment were conducted. The first stage was applying three different products of Coix lachryma-jobi (powder, chop, and straw) in the reactors filled with water from Domestic Wastewater Treatment Plant as a representation of hypertrophic water body. Then the chlorophyll concentration was monitored to indicate algal growth. Another experiment was applying Coix lachryma-jobi in the reactor filled with tap water and water sample. The result of the experiments show that the straw of Coix lachryma-jobi without further physical treatment is the most effective to reduce algae population in the water. However, the mechanism of the algal growth has not been affected by the interactions between Coix lachryma-jobi and the nutrients.
Highlights
There are many ways to define “eutrophication”, but it is widely known as a condition of an excessive amount of nutrients, mainly consist of phosphorus (P) and nitrogen (N), which is caused by anthropogenic activity
The use of barley straw is one of the popular solutions that widely known in United States (US) and United Kingdom (UK)
Barley straw is a local plant from the grain family (Poaceae) with Hordeum vulgare as a nomenclature name
Summary
There are many ways to define “eutrophication”, but it is widely known as a condition of an excessive amount of nutrients, mainly consist of phosphorus (P) and nitrogen (N), which is caused by anthropogenic activity. Barley straw is a local plant from the grain family (Poaceae) with Hordeum vulgare as a nomenclature name. In various studies, this plant has proven to control eutrophication as an algistatic or inhibiting algal growth [1]. This plant has proven to control eutrophication as an algistatic or inhibiting algal growth [1] This is because barley decomposes in aerobic conditions so that phenol compounds such as lignin are dissolved in water bodies thereby inhibiting the algal growth [2]. Similar studies in the following years showed supportive results as well, which showed that barley straw can be used in controlling eutrophication on a laboratory scale [4, 5] and on a field scale [3, 6]
