INTRODUCTION
Indonesia is an agrarian country, which has abundant natural wealth located in a very strategic position. In terms of geography, Indonesia is in the tropics area which has high rainfall.

Theoretical Analysis
The theory used in this study is the theory of social status and social capital theory. The theory of social capital is a social relationship between a group of individuals and families that form a social group including good intentions, a sense of friendship, mutual sympathy and Income Social Capital Business Sustainability cooperation (Hanifan, 1916: 130). Bourdieu defines social capital as the beginning of the formation of a network so as to produce relationships between individuals in society. Relationships that have occurred and perpetuated continuously will lead to mutual recognition between these individuals. In his writing, Bourdieu distinguishes the notion of social capital as consisting of economic capital (economic capital), cultural capital (culture capital) and social capital (social capital). Economic capital is capital that can be converted into money and in the form of ownership. While cultural capital is the academic achievement of individuals. Pierre Bourdieu's concept of social capital shows that there are interdependencies between various types of other capital resources and as embedded in economic capital (Edwards, in Slamet, 2011: 12).
In this study vegetable farmers in the Selo village interacted and cooperated in a system. The vegetable business in Selo Village continues because of a system that supports it from behind. The results of this study showed that the system came from farmer groups. The role of farmer groups in Selo Village greatly influenced the sustainability of vegetable businesses. This research showed that social capital, namely social networks, trust, reciprocity and sharing information could support the sustainability of vegetable farmers in Selo village. In analyzing social capital in vegetable farmers in Selo village, the vegetable business in Selo village is still based on 1) the vast social network owned by farmers to maintain vegetable business, 2) trust held by farmers towards fellow vegetable farmers, middlemen, and local farmer groups, 3) reciprocity between vegetable farmers, middlemen and farmer groups, and 4) sharing information related to vegetable planting.
It can be concluded that the wider the social network owned by vegetable farmers, the easier it is to develop a vegetable business. Conversely, if the narrower social network owned by vegetable farmers, the more possible the business continuity will be narrower. The establishment of social networks between individuals or individuals with groups and the existence of continuous interaction will emerge in trust. The existence of trust results in the attitude of helping each other and sharing information about vegetables.
Vegetable farmers in Selo village view farmer groups as a means to obtain material benefits or other personal benefits so that an increase in income is based on farmers' knowledge of vegetables through farmer groups. Based on the results of the research in Selo Village, it was found that of the 123 respondents surveyed some said that there was an increase in agricultural yields but some said that there was a decline in agricultural yields because the prices of vegetables in the market were declining because some vegetables were experiencing price declines. This happens because of the many yields of certain types of vegetables, with abundant yields, the price of these vegetable decreases and ultimately the income earned also decreases.
The high yields obtained will affect the social status of farmers in the community. The higher the income, the more it affects its social status. Basically social status theory is produced based on the concept of social stratification. Understanding the concept of social stratification refers to grouping people into levels or strata in a hierarchy vertically. Social position (Soekanto, 2012: 210) is a person's place in general in his community with respect to other people, in the sense of his social environment, prestige, and rights and obligations.
