Threats to the unity and integrity of the Indonesian nation (NKRI) that come from within can take the form of:

1. Separatism: Movements or ideologies that seek to establish separate states or regions within Indonesia, challenging the unity of the country. These separatist movements often arise from regional, ethnic, or religious differences and can lead to conflicts and instability.

2. Radicalism: Extremist ideologies, whether religious, political, or ideological, that promote violence, intolerance, or the overthrow of the existing system. Radical groups can undermine social harmony, incite conflicts, and pose a threat to national unity.

3. Corruption: Widespread corruption within government institutions and society weakens the trust and confidence of the people in the state. It undermines the rule of law, hampers development, and erodes the integrity of the nation.

4. Socioeconomic disparities: Wide gaps in wealth and development between regions and social groups can create social unrest and tensions. These disparities can lead to feelings of marginalization, inequality, and resentment, which can threaten national unity.

5. Political instability: Power struggles, weak governance, and political conflicts can create divisions and hinder the progress of the nation. Political instability can lead to social unrest, economic instability, and a loss of confidence in the government.

To safeguard the unity and integrity of Indonesia, it is crucial to address these internal threats through effective governance, inclusive policies, social justice, and promoting a sense of national identity and solidarity among all Indonesians.
