The International Excursion Program (IEP) 2026 is an immersive 3-week field research initiative hosted in Lombok, Indonesia. Centered around the theme "Coexistence of Tradition and Modernity in Economic Development in Indonesia," the program brings together international students, local communities, and academic experts to explore how cultural heritage, grassroots innovation, and environmental sustainability intersect in a rapidly evolving economy. Through 13 curated field excursions across three core pillars—Cultural Diversity & Religious Harmony, Community Innovation & Ecotourism, and Coastal Sustainability—participants gain first-hand insights into local dynamics, practical conservation, and community-driven development.
