Abstract
Sweet potato is a type of secondary crop that is widely cultivated by farmers. The problem often faced by farmers is crop failure caused by pests, diseases and drought. This study aims to descriptively analyze costs, income, net income, profits, and analyze the factors that affect the production of sweet potato farming on the coastal land of Gadingsari Village, Sanden District, Bantul. This study uses primary data from 120 farmers taken at random. Data were obtained by means of interviews through questionnaires. Analysis of costs, income and feasibility using a quantitative approach and analysis of the factors that affect the production of sweet potato on coastal land using the Cobb-Douglass production function approach. The results showed that sweet potato farming in Gadingsari Village was profitable with an income of Rp 2,247,361. Sweet potato farming is feasible to run based on R/C, working economy and working capital. Based on the results of Cobb Douglas analysis, seed, K fertilizer, and labor factors have a significant effect on sweet potato production in coastal land.
Highlights
The utilization of Sanden beach sandy land for sweet potato farming is mostly carried out by the community
The processing of beach sand for sweet potato farming is different from rice fields
This research was conducted in Gadingsari Village, Sanden Sub-District, Bantul, and chose deliberately because this village was the center of sweet potato production in coastal land fields since 1996 [9]
Summary
The utilization of Sanden beach sandy land for sweet potato farming is mostly carried out by the community. The processing of beach sand for sweet potato farming is different from rice fields. One of the physical properties of sand soil is low moisture content, causing farmers to control irrigation. This resulted in farmers issuing higher labor costs for watering. In terms of sweet potato production results produced from sand, fields tend to have smaller sizes, rough appearance, and holes due to pests and fungal diseases. This is similar to the sweet potato, which is produced from rice fields that have better size and appearance. Sweet potato, coastal sand, and paddy fields have a higher selling price of IDR 7,500 per kilogram
