Pemanfaatan Air Limbah Budidaya Ikan sebagai Pupuk Organik Cair Tanaman di Kelurahan Kraton Kabupaten Bangkalan

Waste is a residual material that is not reused, where waste usually comes from an activity or human activity. Waste based on its form can be divided into three: liquid, solid and gas. The waste that is included in the category of liquid waste, for example, is fish farming wastewater. Fish farming wastewater can be harmful to the surrounding environment if there is no treatment process because it contains toxic organic materials. Therefore, there is a need for wastewater treatment, where aquaculture wastewater can be processed into liquid fertilizer for plants. Liquid fertilizer is a liquid fertilizer, made by dissolving aquaculture wastewater mixed with other materials such as molasses and EM4. This community service activity is carried out to provide education to fish farming pond farmers in Kraton Village, Bangkalan about how to treat aquaculture wastewater which can be converted into new products such as liquid fertilizer, so that it can be of economic value and can increase income. Data collection techniques in this community service include interviews and documentation as well as the measurement of production costs by projecting profits and comparing the use of liquid organic fertilizers with inorganic fertilizers (manure, compost, or so on). The result of this activity is an increase in knowledge and insight of pond farmers in processing fish farming wastewater as liquid fertilizer for plants in Kraton Village, Bangkalan Regency.
