This study aimed at examining the analysis of the soil quality index of dry land use on dry land in Blang Bintang District, Aceh Besar District. This research was conducted using a descriptive method based on the results of surveys and field observations as well as laboratory analysis. General biophysical conditions of the area and physical and chemical characteristics of the soil obtained from observations and indicators of soil quality through soil analysis in the laboratory. Soil sampling points were determined using the purposive sampling method, namely the points that have been determined on selected dry land in Blang Bintang District, Regency of Aceh Besar. The moderate soil quality index in the upland land use type is one of the reasons for the sampling of the Inceptisol soil type in the Blang Bintang sub-district, which has less fertile soil characteristics. Upland land use is the percentage of sand (57%) which is greater than the percentage of dust (36%) and clay (6%). This can be seen in the low content of C-organic (1.19), H2O, K-dd, P-available and N-total and high volume weight (1.34).

Biofloc technology (BFT) is an alternative that can be used to provide additional feed source in addition to control and improve water quality for aquaculture. BFT can be done by adding an organic carbon source to increase the C/N ratio in  the culture media to stimulate the growth of heterotrophic bacteria. The results of the observation were that the highest specific growth rate was obtained in treatment B (5ml floc) with an average value of 2.80 grams/day. The highest average length value in treatment B (5ml floc) reached 10.26 cm. The highest survival rate was in treatment B (5ml floc) with an average value of 86.78%. The highest efficiency value was found in treatment B (5ml floc) with an average of 95.90%. Based on Duncan's further test (p<0.05) the application of biofloc with an external carbon source from sweet sorghum had a significant effect on the specific growth rate, absolute growth, survival rate and feed efficiency of tilapia fry. Keywords : Biofloc; Sweet Sorghum; Tilapia Nirwana ; Aquacukture

Soil quality is a useful concept when assessing the sustainability of an agricultural business and demonstrating the ability of soil to maintain plant and animal productivity, improve water and air quality, and protect human health. SQI is a soil variable with the following characteristics: 1) well correlated with ecosystem processes; 2) integration of physical, chemical, and biological soil properties; 3) good sensitivity to human-induced soil changes; 4) simple measurement and interpretation; and 5) Reproducibility Soil quality index (SQI) is a diagnostic procedure to evaluate soil function and overall health. This research was carried out on a unit of land in a dry area in Aceh Besar District with a study area of 239,439.63 ha. Analysis of biomass samples and soil samples was carried out at the Laboratory of Soil and Plant Sciences and Soil Physics Laboratory, Faculty of Agriculture, University of Syiah Kuala. The tools used in this study include a set of computers with the Microsoft Windows 10 operating system that are equipped with several software for analysis, writing instruments, and other supporting tools. The main materials used in this study were soil samples, tree diameter measurement data, and land use maps, including geology, climate, slope class, soil, and topography. The results of the correlation analysis test showed a value of 0.6358. This shows that the relationship between soil C potential and soil quality index is a strong correlation. The distribution of carbon in the soil also has a close relationship with the soil quality index and is an effort to maintain carbon stocks in the soil. C - organic content is a very important parameter in compiling soil quality index criteria. Soil quality can be affected by many factors, such as parent material, environmental factors, land use type, and human activities. The percentage of soil organic C is an indicator of the percentage of soil organic matter (BOT), and BOT is able to improve soil structure and aggregates. Soil organic carbon (SOC) concentration is closely related to soil quality and vegetation productivity. This relationship occurs because of the many contributions of soil carbon to soil properties such as the improvement of soil structure and water retention, provision of cation exchange capacity, and supply of plant nutrients through mineralization. This effect is especially important in small-scale tropical farming systems where the use of external inputs is often limited, and SOC concentrations have been positively correlated with yield levels for a variety of tropical soils.

Nugget ikan adalah salah satu produk diversifikasi hasil perikanan. Daging ikan giling  ditambah dengan bahan pengikat dan bumbu-bumbu yang selanjutnya dikukus dan dicetak. Tujuan penelitian ini adalah untuk melihat pengaruh variasi konsentrasi daging ikan cucut kacangan dan perbandingan bahan pengikat (tepung terigu dan maizena) terhadap mutu nugget yang dihasilkan. Parameter yang  diamati yaitu analisis kadar air, kadar protein, kadar lemak, dan kadar abu. Hasil penelitian menunjukkan bahwa konsentrasi daging ikan cucut kacang berpengaruh sangat nyata (P?0,01) terhadap kadar air, kadar protein, kadar lemak, dan kadar abu. Perbandingan bahan pengikat (tepung terigu dan maizena) berpengaruh sangat nyata  (P?0,01) terhadap kadar protein, kadar lemak, kadar abu dan berpengaruh tidak nyata (P>0,05) terhadap kadar air. Interaksi antara konsentrasi daging ikan cucut kacangan dan perbandingan bahan pengisi (tepung terigu dan maizena) berpengaruh tidak nyata (P>0,05) terhadap kadar air, kadar protein, kadar lemak, dan kadar abu nugget ikan cucut kacang yang dihasilkan. Nugget ikan ikan cucuk kacangan dengan kualitas terbaik diperoleh dari perlakuan konsentrasi daging ikan cucut kacang 30% dan perbadingan bahan pengikat (tepung terigu:maizena) 3:1.

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.
