Lake-based tourism provides significant recreational and ecological services but faces environmental pressures that threaten long-term sustainability. Lake Maninjau in West Sumatra exemplifies this tension between tourism development and environmental degradation from intensive aquaculture. This study estimated the economic value of sustainable lake tourism at Lake Maninjau using integrated valuation methods to inform sustainable development strategies. A mixed-method approach combined Contingent Valuation Method (CVM) and Travel Cost Method (TCM), with 397 visitors surveyed between July and August 2025. Logistic regression analyzed willingness to pay determinants, while Poisson regression estimated recreational demand. 71.3% of visitors expressed willingness to pay for conservation, with mean WTP of IDR 23,500 per visitor (CVM) and consumer surplus of IDR 55,000 per visit (TCM), yielding annual recreational values of IDR 1.37-3.21 billion. Income, education, environmental perceptions, and visit frequency significantly influenced WTP. The dual-method approach revealed substantial economic potential for sustainable tourism, with revealed preferences (TCM) exceeding stated preferences (CVM). Tourism can provide viable economic alternatives to environmentally harmful practices, but requires transparent governance and community participation to ensure sustainable development outcomes. © (2025), (International Information and Engineering Technology Association).
