Abstract

The UNP campus area is crossed by a river that flows from the Basko area to Muaro Gantiang Beach, and this river is known as the "Gangga" River at UNP. The river, which is located right in the Padang State University area, is surrounded by residential areas, so there are many household activities that are directly related to the river. However, the condition of the river when viewed from the surface does not show indications of a clean river, such as cloudy water color and quite pungent odor. Therefore, it is important to do early detection of pollution in order to prevent adverse impacts on the surrounding community. The methods used were observation and experimentation. Pollution detection procedures are carried out through two types of physical and chemical analysis. The test results showed that there were indications of pollution in the Ganges River through simple physical and chemical tests. The results also show that the Ganges River water cannot be used as a raw water source for drinking water needs.

Abstract

The majority of farmers currently use chemical fertilizers and pesticides in farming. However, continuous use of these materials can cause negative impacts such as environmental pollution, health risks, nutrient cycle imbalances, and reduced crop yields. To overcome this problem, research has been conducted that focuses on the use of microorganisms found in the soil layer surrounding plant roots, called the rhizosphere. These microorganisms such as bacteria, fungi and protozoa form a group known as Plant Growth Promoting Rhizobacteria (PGPR). PGPR can increase plant growth through various mechanisms such as nitrogen fixation, phosphorus dissolution, production of cyanide acid compounds (HCN), and Indole Acetic Acid (IAA) compounds. This research aims to collect and analyze articles related to the role of PGPR in sustainable agriculture. The method used is a literature review by collecting sources from Google Scholar and other internet databases. The results of the articles collected were on topics related to PGPR, including mechanisms of nitrogen fixation and phosphorus solubilization, as well as their role in producing IAA and siderophores. Apart from that, the research also discusses the role of PGPR as a biocontrol agent that can control plant pathogens, and the antagonistic activity of PGPR against pathogens.
