The research was conducted at two locations in 2020. The results showed that the use of improved varieties of soybean yielded 2.24 t/ha and 2.09 t/ha, which was higher than using local (non-improved) varieties. The use of improved varieties was financially feasible with Revenue Cost (R/C) ratios of 1.88–1.98 and Benefit Cost (B/C) ratios of 0.88–0.98. The competitiveness of soybeans in Mojokerto and Pasuruan was lower compared to maize and mungbean. Soybean could compete with competing crops if the productivity and price were higher than the current conditions. To be able to compete with maize, the soybean productivity should be 5.14–5.22 t/ha if the current soybean price per kg is IDR 7200 (about US $ 0.51). To compete with mungbean, the soybean productivity should reach 3.05 t/ha with Citation: Krisdiana, R.; the current price per kg of IDR 7200 (about US $ 0.51). When measured by the price level, to be able Prasetiaswati, N.; Sutrisno, I.; Rozi, F.; to compete with maize, the soybean selling price per kg should be IDR 14,428–IDR 14,893 (about Harsono, A.; Mejaya, M.J.

Indonesia0s rice field area in 2015 reached 8,087,393 hectares [2]. Based on data from the Ministry of Agriculture, this number consists of 4.78 million ha of irrigated rice fields and 3.4 million ha of non-irrigated rice fields. These lands have potential for soybean development. Soybean grown on optimal land is more productive and more efficient than dry land. This can be due to optimal soybean growth and does not require inputs (soil amendments) other than fertilization which can be carried out according to recommendations for optimal land. The East Java province is the largest soybean area in Indonesia. The average land area owned by each farmer for food crops, especially soybeans, is less than 0.50 ha. In general, the cropping patterns are rice-rice-soybean, rice-rice-maize, rice-maize-mungbean, and rice-maize-maize cropping patterns. During harvest time, the farmers sell the soybean grains to local markets or to the local buyers who collect the soybean grains from the farmers’ houses. Increasing soybean production in Indonesia to achieve self-sufficiency faces the prob- lem of insufficient harvest area and low crop productivity. For the expansion of the harvested area in Indonesia, there is an optimal area of land, including rice fields. In order for soybeans to develop in these lands, location-specific cultivation technologies that are productive, efficient, economically feasible, and highly competitive are needed. To increase the soybean harvested area, agricultural development is faced with an area of fertile (op- timal) land that is decreasing due to the conversion of its functions to other sectors by 1% per year [1]. Efforts to increase soybean production carried out by the government with the goal of achieving self-sufficiency face three main problems: the harvest area for soybeans is not large enough, productivity is still low, and the competitiveness of soybean commodities is still inferior to other food crops such as peanuts and maize. Therefore, one of the efforts that can be made to increase national soybean production in order to achieve self-sufficiency is to increase the productivity of soybeans, which currently has only reached 1.50 t/ha to around 3.0 t/ha. Soybean cultivation technology is needed in optimal land that can increase produc- tivity, is economically feasible, and has high competitiveness. Technology adoption is a dynamic process that changes over time. Therefore, the technology to be developed needs to be evaluated for its feasibility first at the farmer level. Financial feasibility analysis is an important aspect in assessing product development, because it can determine the feasibility of a business based on the usefulness and benefits it generates. New technology is not only technically feasible for agronomics, but it is also expected to have a direct impact on the acceleration of technology adoption, increase in crop production, and farmers0 income [3,4]. Adaptive and appropriate technology has four characteristics, namely being technically usable, economically beneficial, socially acceptable, and environmentally friendly [5]. The characteristics of innovation will determine whether or not farmers adopt an innovation, namely from the nature of relative advantages, suitability, complexity, ease of trial, and if it can be distinguished from the older technology [6]. Improved varieties are one component of technological innovation that plays an important role in increasing production. Among the technological innovations in soybean cultivation, improved varieties are the most capa- ble technology component for increasing productivity per unit area. The use of improved varieties together with other components of cultivation technology will provide yield increase in order to support national soybean production as well as increase the welfare of farmers. The Indonesian Legume and Tuber Crops Research Institute (ILETRI) has developed several improved soybean varieties. The ILETRI is an institution that conducts research on various legumes and tuber crops. This institution is under the Indonesian Center for Food Crops Research and Development (ICFORD), Indonesian Agency for Agricultural Research and Development (IAARD), Ministry of Agriculture of the Republic of Indonesia. ILETRI has released more than 25 improved varieties with average grain yields of 3 tonnes/ha. More than 3 tonnes of the Breeder Seeds class of these soybean Sustainability 2021, 13, 8334 3 of 12 varieties are distributed annually to seed growers throughout the country to produce the Extension Seeds class for farmers. In carrying out soybean farming, farmers usually use family labor and labor outside the family, depending on their activities. For land preparation activities (cleaning straw, drainage channels), planting, harvesting, and post-harvesting are usually carried out by workers outside the family. Meanwhile, the activities of fertilizing, spraying, and weeding are carried out by family workers. Therefore, the number of family members affects the activities of a farm. Family members who are involved in farming activities usually also have other jobs (besides agriculture) because the activities carried out in the agricultural sector only require a short amount of time. The objective of this study was to determine the financial feasibility of improved soybean varieties and their competitiveness against alternative crops in rice-based cropping systems of Indonesia. 2.
