Abstract

In efforts to minimize the use of inorganic fertilizers and support farmers in using and supplying organic fertilizers independently, the government facilitates providing assistance in the form of Organic Fertilizer Processing Units (UPPO). It is hoped that the availability of organic fertilizers can lead to organic farming. This study aims to determine the role of UPPO on the income of lowland rice farmers in Deli Serdang district and to analyze other factors besides UPPO that affect farmers' income. This research was conducted on eight beneficiary farmer groups spread over seven sub-districts in Deli Serdang district with a total population of 70 farmers. The research method uses analysis of validity and reliability tests, classical assumption tests, and regression analysis. The results showed that all research variables separately had a significant effect on farmers' income.

Abstract

Air pollution, primarily originating from transportation and industrial activities, has become a major concern in the context of environmental health. This study aims to investigate the relationship between air pollution and the morphological characteristics of leaves as well as the stomatal density of the pulutan plant (Urena lobata L.) in polluted environments within the industrial area of Medan and unpolluted environments in Percut Sei Tuan, Medan, North Sumatra. The research method employed is ex-post facto with a laboratory approach to the polluted industrial area. Experimental results indicate that the stomatal density on pulutan leaves in the polluted area, specifically in the Industrial Zone of Medan, is 17.27/mm2, whereas in the unpolluted area, namely Percut Sei Tuan, it is 896.81/mm2. This difference provides insights into the negative impacts of air pollution on pulutan plants, highlighting the importance of maintaining air quality for ecosystem health and human well-being.
