Farmers need organic and inorganic fertilizers that can help increase their agricultural productivity. The same goes for the people of Argapura Village, located in Cigudeg District, Bogor Regency, who are still active farmers and planters. However, most farmers in the village still rely on inorganic fertilizers, such as pesticides, which harm the surrounding ecosystem and tend to cost more than organic fertilizers. To overcome these problems, counselling is carried out regarding the manufacture of organic fertilizers photosynthetic bacteria (PSB), which aims to optimize farmer resources to be able to make fertilizer PSB independently and use it as a supporting fertilizer that can maximize agricultural productivity and reduce the use of inorganic fertilizers. Implementation of counselling begins with measuring the farmers' knowledge of PSB fertilizer, then providing PSB fertilizer material, demonstrating the production of PSB fertilizer, and finally motivating farmers that the resulting PSB fertilizer product can become a business opportunity. Prior to being demonstrated directly to the farmers, PSB fertilizer had gone through experiments and trials on chilli plants as well as the packaging and labelling of finished PSB fertilizer products. The result of this counselling is an increase in farmers' knowledge about alternative fertilizers, namely PSB fertilizer and how to make it, as well as the growth of the entrepreneurial spirit of the farmers. Another result is the creation of PSB fertilizer products and educational videos.
