In an effort to improve methane gas production rate from cattle slurry; ethylene diamine- N, N-diacetic acid chelating ligand was introduced into the digester system. Experimental analysis involving the determination of trace metals, pH and methane gas yi... see more

The Tanjung Formation is one of the coal bearing formations in the Barito Basin, South Kalimantan. The coal seams in the Tanjung Formation in the Arang Alus area have 4 (four) seams,there are seam A, B, C, and D. The age of these coal seams are Eocene - O... see more

The purpose of the work is to reveal the regularities of the influence of the gaseous phase on the process of filtering carbonated liquid and to characterize the physi-cochemical processes during the implementation of the method of reducing mine methane e... see more

This work is devoted to the study of the activity of monometallic (Fe/Al2O3) and bimetallic (Fe-Mo/Al2O3) catalysts supported to carrier ?- Al2O3. It has been discovered that the bimetallic catalyst is more active than the monometallic catalyst in the met... see more

Climate change caused by increasing anthropogenic greenhouse gas concentrations can threaten food security. Agricultural land is a source of food availability, however it is one source of GHG emissions, especially methane and nitrous oxide. Integration ma... see more

Thermal efficiency in the ceramic firing process is crucial to reducing energy consumption, emissions of gaseous pollutants and the cost of production. This study, reports on the determination of thermal efficiencies of a traditional 3m x 28m x 2.7m cross... see more

The livestock sector plays an important role in climate change by contributing to anthropogenic greenhouse gas emissions. Studies to reduce greenhouse gas emissions in production systems of ruminant animals are of particular interest all over the world. M... see more

The rapid increase in the world population increases the need for plant and animal food. Agriculture and animal husbandry practices are becoming more common day by day to meet the need for food and to obtain more products. This situation increases the amo... see more
