This research aims to explore the role of soil microorganisms in improving soil fertility and agricultural productivity to support sustainable agriculture. Using the literature review method, various scientific literatures were analyzed to identify the potential, challenges, and optimization strategies of microorganism technology. Microorganisms such as Nitrobacter, Streptomyces sp. and Trichoderma sp. play significant roles in nitrogen cycling, organic matter decomposition and plant pathogen control. In addition to naturally improving soil nutrition, these microorganisms also support agricultural efficiency by reducing dependence on synthetic chemical fertilizers and pesticides.  However, the adoption of this technology faces obstacles, such as farmers' lack of knowledge and limited access to quality products. Therefore, strategic steps are needed in the form of training programs, extension, and policy development to support the implementation of microorganism-based technologies. In the context of climate change, microorganisms also contribute to greenhouse gas mitigation and increase crop tolerance to abiotic stress. The results of this study emphasize the importance of microorganisms as a sustainable solution to the challenges of modern agriculture, as well as the need for collaboration between various parties to increase the capacity of farmers in implementing this technology. 
 

This study examines the main pests and diseases that attack cayenne pepper (Capsicum frutescens) plants grown in polybags. In Indonesia, this crop is in high demand for both household and industrial use. Nonetheless, farmers often face challenges from pest and disease attacks, including anthracnose, fusarium wilt and stem rot, leading to reduced yields. The methodology used was a literature review covering various sources related to cayenne pepper. Findings show that important diseases such as anthracnose can reduce yields by up to 80%, while pests such as fruit flies can cause chili fruits to drop prematurely before harvest. Effective pest and disease management is essential to increase the productivity of cayenne pepper cultivated in polybags.
