In the pursuit of sustainable farming and waste management, researchers have explored innovative ways to repurpose livestock manure. One promising approach is the production of biochar briquettes, which serve as an eco-friendly fuel source. A recent study by Prabo, Rosnah, Noach, and Dato from Universitas Nusa Cendana investigates the physicochemical properties of biochar briquettes made from mixtures of goat dung, saboak shells, and corn cobs.

The study utilized a randomized design with four treatment variations, each combining different proportions of goat dung, saboak shell charcoal, and corn cob charcoal. The treatments were as follows: P1: 25% goat dung + 75% saboak shell; P2: 25% goat dung + 50% saboak shell + 25% corn cob; P3: 25% goat dung + 25% saboak shell + 50% corn cob; and P4: 25% goat dung + 75% corn cob. Key parameters measured included yield, density, moisture content, ashAsh is the non-combustible inorganic residue that remains after organic matter, like wood or biomass, is completely burned. It consists mainly of minerals and is different from biochar, which is produced through incomplete combustion.   Ash Ash is the residue that remains after the complete More content, calorific value, volatile matterVolatile matter refers to the organic compounds that are released as gases during the pyrolysis process. These compounds can include methane, hydrogen, and carbon monoxide, which can be captured and used as fuel or further processed into other valuable products.   More, and fixed carbon.

The findings revealed that increasing the proportion of corn cob charcoal significantly enhanced the calorific value of the briquettes, making them more efficient as a fuel source. Specifically, the highest calorific value was observed in the P3 treatment, which combined 25% goat dung, 25% saboak shell, and 50% corn cob. This mixture produced briquettes with a calorific value of 5345.48 cal/g. Additionally, this blend maintained satisfactory levels of moisture content, ash content, volatile matter, and fixed carbon, similar to the other treatments.

The study concluded that incorporating corn cob charcoal into the mixture with goat dung and saboak shells significantly improves the energy content of biochar briquettes. This approach not only enhances the utility of agricultural waste but also contributes to more sustainable and eco-friendly farming practices. The optimal mixture identified in the study (P3) presents a viable solution for producing high-quality biochar briquettes with improved combustion properties.
