Recovery Nutrient from Agricultural Waste as An Effort To Develop Low-Carbon Agriculture In Thekelan Hamlet

Abstract

Abstract Thekelan Hamlet is located on the slopes of Mount Merbabu which is included in the Mount Merbabu National Park area. The majority of people earn from agriculture and animal husbandry because there is still a lot of land for farming. In the process of agricultural activities, residual materials or so-called agricultural waste are produced in the form of solids or liquids. In Thekelan Hamlet there is no agricultural wastewater treatment, so there is a need for agricultural wastewater management. One of them is by reusing nutrients so that they are still useful and do not pollute the environment. In agricultural wastewater, many types of nutrients can be reused, such as nitrogen and phosphate. So that the recovered nutrient content can be reused and processed into fertilizer. This will support the development of low-carbon agriculture in Thekelan Hamlet. The activity of reusing nutrients from agricultural liquid waste is also supported by the existence of a building to catch and process nutrients for agricultural liquid waste. The agricultural liquid waste runoff will be made into waterways according to the elevation of the land to eventually be accommodated in a storage building and processed into fertilizer with a certain concentration.
