Bhinneka Tunggal Ika, Indonesia's national motto, serves several important functions. First, it promotes national unity and integration by acknowledging and celebrating the country's diverse cultures, ethnicities, and religions. Second, it acts as a unifying force, reminding Indonesians of their shared identity and destiny. Third, it fosters tolerance and mutual respect among different groups. Fourth, it guides national policies and decision-making, ensuring that the rights and interests of all citizens are protected and that diversity is embraced as a source of strength.
