Abstract

This study aims to determine the potential of soil carbon on dry land in Aceh Besar regency. This study uses a descriptive method based on field results and surveys and laboratory analysis. Soil sampling at various depths was carried out for carbon and bulk density analysis. Composite soil samples were taken at a depth of 0-5, >5-10, >10-20, >20-30, >30-70, and >70-100 cm. The type of land use is bush covering an area of ??96,962.2 ha, moor 313.03 ha, rainfed rice fields 4,478.67 ha and mixed gardens 15,052.09 ha. The highest percentage of soil carbon is in the mixed garden land utility type (3.40%) compared to other types of utility. the highest carbon potential is found in the bush land utility type (137.68 tons/ha) compared to other types of utility. The highest soil carbon stock is in the type of land use of bush compared to other types of land utility. This is because the bush land utility type has soil carbon potential and a large area compared to other land utility types.

Abstract

Pump that operates automatically by relying on natural power from water without using great cost and trouble by pumping hydram. Hydram pumps are one of the types of pumps that are driven by kinetic power, it was discovered by a 1796 Montgolfier in Italy. The purpose is to determine the most optimal water speed of the hydram pump by using different numbers of pressure tubes and several check valves. This research uses a factorial Randomised Group Design (RGD) method. The first treatment is valve variation and the second is variation in the number of tubes. The results showed that the average river water flow velocity was 0.154 meters/second with an average water discharge of 2.61 m3/second under normal flow conditions. The average water flow in the intake pipe is 0.717 meters / second and the volume of water in the pipe is 15.19 liters with an average water discharge entering the intake pipe is 10.804 m3 / second. A combination of three valves and three tube treatments consistently produces greater water discharge than other combinations. The highest efficiency of the hydram pump is found in the combination of three checks.
