West Java, is an example of ex-situ conservation developed through conservation-based educational tourism and ecotourism. This activity not only supports wildlife preservation but also functions as a medium for environmental education, nature recreation, and local economic development (Ceballos-LascurĂ¡in, 1996; Das & Chatterjee, 2015). Conservation-based tourism is considered capable of promoting sustainable environmental management by encouraging responsible use of natural resources and increasing public awareness regarding wildlife conservation (Fennell, 2020; Tisdell & Wilson, 2012). This study aimed to analyze operational costs, revenue, profit, and the business feasibility of deer captive breeding at Wana Wisata Cariu as a conservation-based educational tourism destination. The study applied a quantitative descriptive method using a case study approach. Data were collected through field observations, interviews with the management, documentation, and literature review. Data analysis was conducted by calculating total operational costs, total revenue, business profit, and the Benefit Cost Ratio (BCR) to determine business feasibility (Boardman et al., 2018). The results showed that the total operational cost of the deer captive breeding business reached Rp. 29,209,000 per month, including feed, vitamins, health examinations, and labor expenses. Tourism revenue reached Rp. 45,000,000 per month, with an average of 150 visitors per day and an entrance ticket price of Rp. 10,000 per person. The business generated a monthly profit of Rp. 15,791,000. The BCR analysis produced a value of 1.54, indicating that the business is economically feasible because the benefits obtained are greater than the operational costs incurred. The success of deer captive breeding tourism development is influenced by feed management, animal health, cage sanitation, tourism services, and environmental management. Therefore, deer captive breeding at Wana Wisata Cariu has strong potential to be developed as a sustainable and economically valuable conservation tourism destination.
