Abstract

Sweeth Orange cultivar Selayar is a local superior orange of South Sulawesi that has been registered with the Ministry of Agriculture since 2005 which is expected by local governments to be one of the commodities that can increase people^s income, but in its development so far there were often encountered a various of problems. This study aimed to identify the problem of orange on the field and to know the prospect of sweet orange agribusiness. The research was conducted at three centers of development of the orange Selayar, namely Bontomatene, Bontosikuyu, Bontoharu districts. Data collection was carried out using survey methods and interviews with citrus farmers and related agencies. The data that has been obtained are analyzed by qualitative and quantitative descriptive methods. To analyze the income of farmers from citrus farming was calculated by the ratio of revenue and costs (R/C ratio). The results showed that the area of potential development of Selayar oranges reached 6,750 ha, but until 2019 the area planted was only 1,935 ha with a population of
779,761 trees. Strangely, planting is expanding, but the annual production is decreasing. Various factors include:, the high attack of various pests especially blendok disease and CVPD,
availability of water during dry season, procurement of seedlings with rootstock Selayar replacing Japanese citrone and provision seedling without indexing systemic diseases. The net
income level of citrus farmers in Selayar Regency is on average only IDR 70,000,000/ha/year or 17.5% of the potential land that must be obtained, whereas if cultivated properly can
produce IDR 400,000,000/ha/year. The prospect of sweet orange agribusiness is very feasible to be undertaken if properly cultivated with the level of income can reach IDR 97,000,000 in the 5th year and IDR 457,950.0000 in the 12th year with RC ratio of 5.2 and 21.8.
