The Women Farmers Group (KWT) is a group of farmers who empower women to build an agricultural group. The activities of the farmer groups are agricultural cultivation and processing of agricultural products which can be useful for increasing farmers' income. However, the current income of farmers is still low due to a lack of media transactions and promotions. One of the ways to increase agricultural output is by utilizing farmer groups. This research was conducted at the Flamboyan Women Farmers Group (KWT), which is a group of women in Kalirejo Village, Kalirejo District, Central Lampung Regency who have agricultural products that are processed into food products. The KWT has only been established for about a year and has ten members. However, KWT Flamboyan has not been able to promote its products widely in other regions. Until now, the promotion has been ineffective because it was done when there was a gathering. Therefore, to help increase sales of processed agricultural products. This study uses Android-based M-commerce as a medium for the transaction, promotion, communication, and information to increase the income of the farmer group. Researchers used a structured prototyping system development method with the interaction and system users and used a fishbone research framework to identify causes and effects in the group.
