AbstractPresent study aimed to perform literature review to investigate the current status and potential use of plant growth promoting rhizobacteria (PGPR) for enhancing the soil plant’s health, plant growth and productivity in sustainable ways. The Systematic Literature Review (SLR) methods was applied according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) on published scientific literature from 2012-2022. Results revealed that genus diversity of PGPR (Bacillus sp., Serratia sp., Streptomyces sp., Pseudomonas sp., and Burkholderia sp.) produce siderophore and phytohormones such as indole-3-acetic acid (IAA), gibberellin (GAs), auxin, and 1-aminocyclopropane-1-carboxylic acid (ACC) deaminase activity, organic acids, biocontrol agent that contribute to the improvement of nutrient bioavailability (nitrogen fixing, phosphate solubilizing and Fe-uptake). The growth character of rice inoculated with biofertilizer and combined with 50% inorganic fertilizer produced no significant difference with pots that received 100% inorganic fertilizer. These results concluded that PGPR that produced phytohormone and siderophore could be developed as a potential bioagent or biofertilizer to improve the growth character and yield of upland rice (Oryza sativa L.) in dry environmental conditions.Keywords: PGPR producing phytohormone and siderophore, N2-fixer, Biofertilizer, Systematic review AbstrakKajian tinjauan pustaka ini dilakukan untuk menyelidiki status saat ini dan potensi penggunaan rizobakteri pemacu pertumbuhan tanaman (PGPR) untuk meningkatkan kesehatan tanah, pertumbuhan tanaman, dan produktivitas secara berkelanjutan.

Soil fertility is recognized as a crucial factor in supporting plant growth and productivity. The utilization of biofertilizers as environmentally friendly fertilizers is aimed at enhancing soil fertility and plant productivity. This study aims to explore the potential of local material for developing local wisdom biofertilizers (LWB) for achieving sustainable agriculture. A systematic literature review was conducted using bibliometric analysis, Preferred Reporting Items for Systematic Reviews, and Meta-Analyses (PRISMA) method, employing the Scopus search engine with the keywords "local AND wisdom AND biofertilizer" OR "biofertilizer" OR "local AND microorganism" OR "soil AND health OR crop AND productivity OR sustainable agriculture". The search yielded 704 articles, of which 11 were deemed eligible after selection. Based on the literature review, it was found that there are local materials, including fish waste, seaweed, Azolla, fruit waste, Moringa oleifera, microalga, bamboo roots, banana hump, golden snail, mangrove leaves, fruit, and vegetable waste that can be used as raw materials for LWB to improve soil health, plant growth, and productivity. The development of LWB as a new fertilizer technology faces challenges such as lack of regulations, low public trust, limited farmer awareness, weak promotion, and raw material shortages. Further research is needed to intensively study and enhance the effectiveness of LWB through enrichment using beneficial microorganisms.
