This study was carried out on a 239,439.63 ha unit of dry land in the Aceh Besar Regency. The Soil and Plant Science Laboratory and the Soil Physics Laboratory at the Faculty of Agriculture, Universitas Syiah Kuala, analyzed soil and biomass samples. Twelve different land use types in the Aceh Besar Regency's dry land are the research locations. Utilizing a methodology with the number SNI 7724:2011, the Indonesian National Standards Agency established the biomass measuring and sampling procedure in 2011. According to the study's findings, the primary forest land use type has the greatest potential for absorbing CO2 in the forest land use type, followed by the following. Pine forest, secondary forest, teak forest, eucalyptus forest, and bush forest, in that order. In contrast, the land use categories of mixed gardens, moors, bushes, grassland, rainfed rice fields, and bare ground have the highest potential for absorbing CO2. Primary forests have the largest overall carbon dioxide absorption among the many forest land use types. These are followed, in order, by secondary forests, bush forests, eucalyptus forests, pine forests, and teak forests. The primary forest land use type has the largest total CO2 absorption among the non-forest land use types, followed by grasslands, shrubs, mixed gardens, rainfed rice fields, moorland, and bare ground, in that order. The Aceh Besar Regency's numerous dry land uses can benefit from enhanced natural and environmental sustainability due to the wide stem diameter and abundance of woody plants, which can also increase CO2 absorption. Highlights High CO2 potential and sequestration are critical in controlling climate change Humans play an important role in regulating and maintaining the availability of plants to maintain environmental stability. Forest protection plays an important role in maintaining the biodiversity of plants, animals, and endangered species in protected forest areas.

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.

This study aims to design a roaster to produce three roasting categories: light roast, medium roast, and dark roast and obtain quality coffee beans. The research was conducted in the laboratory of the Agricultural Mechanization Workshop of the Politeknik Indonesia Venezuela. This research uses the Trial and Error method. This research uses the Trial and Error method. During the process of roasting coffee beans, observations were made of temperature, length of time and knowing the maximum capacity of the tube and the maximum temperature level of roasting. The design of the coffee bean roaster is also classified as different from other tools or machines because it uses a heating element (heater) that can be adjusted according to the roasting desire. The response method in this study includes the temperature and length of time used during the roasting process where a system to control the situation so that the results obtained correspond to the desired value as effectively as possible. Based on the results of functional and structural tests, the roaster that has been designed can work properly. The capacity of the roasting tube that has been designed produces a volume of 9.42 liters equivalent to a coffee weight of 2 kg. The working capacity of the tool produces 2.4 kg/hour for Light Roast criteria, for Medium Roast criteria produces 1.7 kg/hour, and for Dark Roast criteria produces 0.8 kg/hour. The average temperature distribution for Light Roast material is 97 ° C, Medium Roast is 110.83° C, and Dark Roast is 131.25° C.

This study aims to determine the analysis of soil quality index in pine forest land use type on dry land in Aceh Besar Regency. This research focused on several field observation points in the pine forest land use type area on dry land in Aceh Besar Regency. The soil quality index in the pine forest land use type in Aceh Besar Regency is included in the medium category. This is due to soil sampling on the inceptisol soil type in Aceh Besar Regency, which has characteristics of less fertile soil. Soils that have a high percentage of dust have a higher risk of erosion, because dust has a relatively small size so that it is easily washed away by surface flow. low C-organic content, high volume weight, pH H2O, K- exchangeable, P-available and low N-total. In the type of pine forest land use, special treatment is needed in the form of adding organic matter to the soil by fertilizing, reforesting pine plants and conducting drainage so as to reduce nutrient leaching in the top soil layer.

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.
