Background: At this time the food industry sector is growing very rapidly and increasing fierce competition among business people such as the tofu industry in Banda Aceh City. This encourages the importance of the application of SCP in describing the overall state of the market both the structure, behavior, and performance resulting from industry. Aim: This research aims to describe the structure, behavior, and performance of the industry as well as the influence of these three dimensions on the tofu industry in Banda Aceh City. Method: This study uses a quantitative approach and uses a census method where the population is all tofu producers registered with the Banda Aceh City Labor Office in the industrial section of 2019-2020 which amounted to 13 industries. CR4 and IHI analysis is used to measure structure, CLR analysis is applied to measure behavior, and PCM is used to improve the performance of the tofu industry in Banda Aceh City. The effect test on 3 dimensions is measured using Path Analysis. Findings: Found CR4 values 36.43 percent, IHI 729.99 points, CLR 11.06 percent, and PCM 12.08 percent. As well as found the relationship of variable MS to PCM positive and significant, clr relationship to positive PCM is not significant and the relationship of MS to PCM through positive CLR is not significant.

Most of the coastal zones of Aceh Besar are areas of accumulation of organic compounds such as C-Organic and CaCO3. Therefore, studying the distribution of organic carbon and carbonates in sediments in coastal areas is necessary. This study aims to analyze the distribution of C-Organic and Calcium Carbonate (CaCO3) coupled with pH and Salinity tests spatially on the surface at a depth of 40 - 60 cm in the coastal area of Aceh Besar District. The C-Organic content was analyzed using the Walkley and Black method, while Calcium Carbonate (CaCO3) was analyzed using the Titrimetric method. Soil pH and salinity tests were carried out in situ using a pH meter, and soil salinity tests were tested using a salinometer. The study results show that the distribution of C-Organic and Carbonate content differs in each location in Aceh Besar Coastal area. The distribution of organic carbon and carbonates in the northern part of Aceh Besar, in the Ujong Batee Puteh area, has an average value of 0.86% and 10.28%. While the distribution of C-Organic in the Lamreh area is, on average, 0.44%, and carbonate (CaCO3) is 8.03%. On the other hand, in the western part of Aceh Besar, the distribution C-Organic in the Ujong Pancu area is, on average, 2.83%, and carbonate (CaCO3) is 8.05%. The distribution of C-Organic in the Lhok Seudu area has an average value of 1.07% and carbonate (CaCO3) of 9.65%. The results also reveal the fact that there are 3 (three) factors that influence the distribution of C-Organic and CaCO3. These factors are the topographic location that allows the material to be eroded due to runoff, vegetation that enriches organic matter composition, and the depositional environment. The results of the pH distribution test in soil showed that the pH in the coastal area of Aceh Besar is relatively alkaline, and the salinity distribution is relatively low, indicating the absence of seawater intrusion and salt deposits. Further studies need to be carried out for other depth variations to obtain more comprehensive results of other distributions.

The Atomic Absorption Spectrophotometer method (AAS) and UV-Vis Spectrophotometer method are often used in analyzing elements and compounds in water and sediment. The comparative method of AAS and UV-Vis analysis in sediments in this article is studied to see the accuracy of the equipment used and the efficiency of the resulting analysis. Analysis of the comparative method of phosphate analysis in coastal sediments shows differences and similarities in the use of the two instruments used even though the methods used based on the results of the review do not show significant differences. Methodologically, various types of methods can be carried out to analyze coastal sediment phosphates. The UV-Vis spectrophotometric method is generally more widely used than the AAS method. For a small number of sediment samples, the ASS method is more efficient than the UV-Vis method; however, UV-Vis is more accurate for dissolved samples because less phosphate is released when identified than the AAS method. Based on this, the AAS method is more effective in analyzing phosphate sediments in coastal areas than the UV-Vis method, but the UV-Vis method for wet samples is more accurate.Keywords:Coastal SedimentPhosphateSpectrophotometerUV-VisAAS

Abstract. This study aims to analyze the area and distribution of land cover in the last 10 years in the Krueng Aceh and evaluate the alignment between the regional spatial plan (RTRW) and the land cover in the Krueng Aceh watershed. The results of the analysis were obtained through digital image processing derived from Landsat 7 ETM 2009 and Landsat 8 OLI 2020. This study shows that land cover in the form of primary forest has changed from 2009 to 2020, wherein 2009 primary forest cover had an area of 60,245.62 ha or 34.11% of the entire area while in 2020 it was reduced to 48,512.00 ha or 27.47% of the entire area. And Based on the results of the evaluation of the consistency of land closure conditions in the Krueng Aceh watershed against the Aceh Provincial RTRW, 98.40% of the area of the Krueng Aceh watershed obtained land cover consistent with the RTRW. But Based on the results of the Evaluation of the Consistency of Area Status in the Krueng Aceh River Basin against the Aceh Province RTRW, it was found that an area of 176,301.71 ha or equal to 99.99 % of the area of the Krueng Aceh River Basin, the status of the Area was consistent with the RTRW.
