This study aims to find out the most compatible method specification used to forecast the production and prices of red chili and to analyse the results of the production and prices forecasting of red chili in North Sumatera in 2028. The analytical methods used are the linear trend analysis, quadratic trend analysis, and exponential trend analysis where the three method specifications will be tested with MSE and MAPE to see which one is the most compatible. The results indicated that quadratic trend analysis is the most compatible one and that both the production and the prices forecasting are having a negative trend. The decreasing of production is caused by the decreasing of red chili’s planting area while the decreasing of prices is caused by the decreasing of demand for red chili.
This study examines the impact of industrial agglomeration on air quality, economy, and social aspects in the Medan City area. The findings reveal that industrial agglomeration in the Medan Deli District significantly influences air quality parameters, such as Nitrogen Dioxide (NO2), Sulfur Dioxide (SO2), Carbon Monoxide (CO), Hydrocarbons (HC), Ozone (O3), and Particulate Matter (PM10 and PM2.5). As industrial agglomeration increases, air quality deteriorates compared to non-agglomeration areas. Furthermore, industrial agglomeration has notable effects on the economy and social well-being of the community, leading to job opportunities and a favorable business climate. To mitigate the negative impact on air quality, it is crucial for industrial stakeholders, the community, and the government to actively monitor and regulate emission sources, such as combustion engines, while conducting routine ambient air quality monitoring around the Medan Industrial Area. These measures will contribute to improving both the environmental and socio-economic conditions in the region.
