Utilization of saline land as an effort to increase rice productivity is still constrained by the adverse effects salinity stress. The solution this can be done utilizing PGPR biofertilizers and applying ameliorant briquettes. purpose study was evaluate effect using briquettes on soils with various levels growth plants. This research conducted at Ciparanje Jatinangor screen house from September...

Electric arc furnace dust (EAFD) is generated in considerable amounts by the electric arc steelmaking process. During melting in an electric arc furnace, certain elements volatilize, and form fine dusts after cooling. The EAFD is collected in a baghouse and amounts to approximately 1–2 wt% of the steel produced.1) In China, about 800 million tons of steel was produced in 2015 with more than 9 w...

Torrefaction process of biomass material is essential in converting them into biofuel with improved calorific value and physical strength. However, the production of torrefied biomass is loose, powdery, and nonuniform. One method of upgrading this material to improve their handling and combustion properties is by densification into briquettes of higher density than the original bulk density of ...

Tobacco stems contain 56.10% cellulose content, 15.11% lignin, 22.44% hemicellulose, and 44.61% total organic carbon, which can be used as a source of energy or fuel. This study aimed to utilize tobacco in briquette form alternative energy. The materials this were stem waste, rice husk, wood charcoal, coconut shell. treatments consisted T1 (100% stems), T2 (80% + 20% shell), T3 husk), T4 (33.33...
