Abstract
Marine debris was a direct threat to marine habitats, human health, and navigational safety, resulting in serious socio-economic losses. Marine organic waste management can be done by turning it into compost that can be used as a nutrient addition. It can also be used as a solution to be diminished marine waste considering that the sea had many roles to support the lives of living things and maintain ecosystems. This study aimed to examined some characteristics of compost from marine organic waste and gave information on waste management for sustainable agriculture. This study was carried out at Kuala Indah Beach, Sei Suka District, Batu Bara Regency, Indonesia. The composting process was carried out at the Faculty of Agriculture, Universitas Sumatera Utara. The analysis was carried out at the Research and Technology Laboratory of the Faculty of Agriculture, Universitas Sumatera Utara. The composting process used the Berkeley method with the addition of EM4. The results showed that the chemical characteristics of marine organic waste compost by Indonesian National Standard (SNI 19-7030-2004) with a macronutrient content of 2.40% Nitrogen; Phosphorus 0.53%; and Potassium 0.45% with a pH of 6.95 (neutral) and a compost C/N ratio of 17.33.
