Information technology is a technology that is growing rapidly today. Technology has a very important role in human life. The impact of the development of information technology is the increasing need for the use of computers. The use of computers in East Borneo (Kalimantan) is also not spared. East Kalimantan is one of the provinces with rubber plantations that have begun to be developed, but unfortunately due to the lack of knowledge and knowledge of the community regarding the management of agricultural products, the sale of rubber latex in East Kalimantan has not developed. Farmers can only sell rubber latex to middlemen at prices below the market. Therefore, the people of East Kalimantan need a forum for promoting agricultural products, so that they can attract buyers from outside the area and can get prices according to the market. To help people in East Kalimantan, in terms of marketing rubber products, a Rubber Sap Processing Website was created. The purpose of this paper is to increase the knowledge of processing and selling rubber products by the farmers while at the same time helping the welfare of the farming community, especially in the East Kalimantan area. The method used is Software Development Life Cycle (SLDC), the result is a website for the introduction and processing of rubber latex in East Kalimantan. The results of this study are the creation of an information system for rubber latex processing that helps farmers sells their harvests in online platform.
