Agricultural waste treatment is an organism that offers innovative solutions to reduce the negative environmental impact of waste while increasing agricultural productivity. By using microorganisms such as bacteria, fungi, and actinomycetes, wastes such as straw, manure, and coffee grounds can be effectively treated. This biological process accelerates the decomposition of organic matter into more benign substances and nutrients, such as nitrogen, phosphorus and potassium, which are essential for plant growth. In addition to improving soil fertility, the use of organic fertilizers also reduces dependence on chemical fertilizers, greenhouse gas emissions, and sustainable agriculture. The aim of this study was to investigate the role of microbiology in agricultural waste transformation by examining its mechanisms, potentials, and challenges. The results of this study show that microorganism-based technologies contribute to more environmentally friendly practices and reinforce fundamental economic principles. Processing agricultural waste into organic fertilizer is a strategic step in realizing sector sustainability.

Global food demand continues to increase, but over-farming without considering environmental sustainability has led to land degradation. This can result in decreased crop yields. However, this problem can be solved by applying environmentally friendly farming methods using beneficial microbiomes that can improve soil health and increase crop productivity. This research aims to explore the role of the soil microbiome in enhancing crop productivity and crop resilience to biotic and abiotic stresses and supporting soil health, which enables the use of eco-agricultural approaches to solve these problems. This research utilizes the literature review technique, which involves analyzing, summarizing, evaluating and synthesizing documents from various references. This method aims to improve our understanding of how microorganisms promote plant growth in degraded soils. The results show that soil microbes improve soil quality and control plant diseases. Crop production on marginal lands can be sustainably increased with the use of the microbiome. In addition, the microbiome helps sustainable agriculture by reducing our dependence on synthetic chemicals, reducing environmental pollution and supporting food security worldwide, and supporting food security worldwide.
 

Garut is one of the areas that has local cultural wisdom that is still beautiful and preserved. The diversity of existing plants has sufficient economic value and has potential as alternative ingredients and medicines. The people of Garut still cultivate and use plants as alternative medicines that can cure various diseases. The Mustajab plant or Gedi Leaf with the scientific name Abelmoschus manihot of the Malvace family is one of the herbal plants that has long been used by the people of Sindangsari village as a fever reducer or pyretic in babies. Pyretics is a condition in which the body experiences an increase in temperature above normal limits due to a response to infection or inflammation. This research was conducted in Sindangsari Village, Leuwigoong District, Garut Regency. The method used in this research is an exploratory survey method. The data collection technique uses a purposive sampling method. This research data analysis uses qualitative and quantitative methods. To calculate the use value, the UV method is used. Apart from that, the Fidelity Level Index (FLI) method is also used. Mustajab leaves are included in the category of plants with metabolite compounds which can produce compounds from the soil itself. Mustajab leaves can cure fever in babies because they contain many active compounds, one of which is flavonoid compounds. Based on the results presented in the table, it can be seen that the highest FL value is in the mustajab plant which is used as a treatment for fever in babies with a FL value of 51.5%. Based on the results table, it can be seen that the highest UV value is in the use of mustajab leaves as a medicine for baby fever with a UV value of 0.51. There are many processing and application methods for using mustajab leaves as traditional medicine, including boiling, squeezing and pounding. Based on the data above, it can be concluded that mustajab leaves are one of the traditional food plants which are usually used by rural communities as an alternative medicine to reduce fever in babies.

Soil microorganisms play an important role in increasing nutrient availability for maize plants through the processes of nitrogen fixation, phosphate solubilization, and humic acid production. These processes not only increase maize productivity but also reduce dependence on synthetic chemical fertilizers, thus supporting agricultural sustainability. This study explores the benefits of microorganisms such as Rhizobium, Azospirillum, Pseudomonas, and arbuscular mycorrhizal fungi in enhancing nutrient uptake, protecting plants from environmental stress, and improving soil quality. Challenges in the application of microorganism technology include adaptation to diverse environmental conditions and low farmer adoption. However, advances in genomic technology and biotechnology open up opportunities to optimize the benefits of soil microorganisms. The implementation of this microorganism-based technology has the potential to support efficient, environmentally friendly and sustainable maize farming.

The process of organic matter degradation is an integral part of the ecosystem cycle, which converts complex organic compounds into simpler forms through the activity of microorganisms. Microorganisms, such as bacteria, fungi, and actinomycetes, play an important role in the decomposition of organic matter, whether from household waste, crop residues, or organic industrial waste. This process involves various biochemical mechanisms, such as hydrolysis, fermentation, and oxidation, which are triggered by exocellular enzymes produced by microbes. Environmental factors, such as pH, temperature, humidity, and oxygen content, affect the efficiency of degradation by microorganisms. Several microorganisms, especially those that have the ability to decompose lignin, cellulose, and hemicellulose, have been widely applied in organic waste management technologies such as composting, bioremediation, and biogas production. Research on the role of microorganisms in organic matter degradation is not only important for understanding ecosystem dynamics, but also has the potential to support efforts to manage organic waste that are more environmentally friendly and sustainable. This abstract provides a review of the role, mechanisms, and factors that influence organic matter degradation by microorganisms, as well as their applications in environmental technology.
 

This research is about the influence of biochar, a carbon-rich material from biomass pyrolysis, on soil quality in a sustainable agricultural system. Biochar plays an important role in increasing soil organic content, improving soil structure, increasing crop productivity, and reducing greenhouse gas emissions. Research results show that biochar application can increase air and nutrient retention, improve soil biological activity, and reduce dependence on chemical fertilizers. In addition, biochar contributes to climate change mitigation through carbon storage and reduces dependence on chemical fertilizers. Thus, biochar has great potential as an innovative solution to support productive and environmentally friendly agriculture. Biochar also helps to create a more productive and environmentally friendly farming system, making it relevant as an innovative solution in supporting agriculture.
