A team from the Institut Teknologi Sumatera (Itera) has introduced an innovative, environmentally friendly fertilizer to farmers in Merak Batin Village, Natar District, South Lampung Regency. The initiative, which took place on Saturday, September 6, 2025, saw lecturers and 12 students from Itera’s Community Service (PkM) program introduce a slow-release NPK fertilizer that utilizes biocharBiochar is a carbon-rich material created from biomass decomposition in low-oxygen conditions. It has important applications in environmental remediation, soil improvement, agriculture, carbon sequestration, energy storage, and sustainable materials, promoting efficiency and reducing waste in various contexts while addressing climate change challenges. More as a key component. This project aims to boost rice productivity while promoting long-term soil health.

The program, which received full support from Merak Batin Village Head Aldin and involved 12 local farmer groups, highlights a growing trend in agriculture towards more sustainable and efficient nutrient management. The use of slow-release fertilizers, particularly those incorporating biochar, represents a significant shift away from conventional synthetic fertilizers. These traditional products often lead to nutrient runoff and soil degradation over time. The biochar-based fertilizer, composed of rice husk charcoalCharcoal is a black, brittle, and porous material produced by heating wood or other organic substances in a low-oxygen environment. It is primarily used as a fuel source for cooking and heating.   More, clay, and water, is designed to release nutrients gradually. This controlled release mechanism ensures that plants receive a steady supply of nitrogen, phosphorus, and potassium, minimizing waste and the negative environmental impacts associated with excessive chemical application.

Dr. Edwin Rizki Safitra, S.Si., M.Eng., an Itera lecturer, explained the composition of the fertilizer and its benefits. By providing a sustained nutrient source, the slow-release formula not only increases efficiency but also helps reduce the overall quantity of fertilizer needed. The Itera team also supplied the farmers with a pelletizer tool, enabling them to produce their own biochar-based fertilizer. This move towards localized production empowers the community and reduces their reliance on external, often costly, inputs. The project aligns with broader industry goals of advancing circular economies in agriculture, where agricultural byproducts like rice husks are repurposed into valuable soil amendments. This approach is particularly relevant in Indonesia, where maintaining a high rice yield is critical to meeting national food demands. Through this effort, Itera is fostering greater awareness among farmers about agricultural technology that enhances harvest yields and sustains soil fertility for future generations.
