Political actualization of citizenship is related to membership, legal status, rights, and participation which are the four key dimensions of citizenship. These four aspects need to be immediately actualized in the life of the nation and state, because they are very important in realizing a civilized nation. The problem of not achieving the political dimension of citizenship is due to a decrease in the sense of nationalism in each younger generation. On that basis, the National Unity and Political Body (Bakesbangpol) of Bandung City organizes state defense education. The purpose of this study was to analyze the state defense education conducted by Bakesbangpol of Bandung City to strengthen the character of love for the homeland of the younger generation. The theory used is the theory of nationalism, political theory of citizenship and the conception of state defense. This analysis uses a qualitative methodology with a case study approach, with data collection strategies through interviews, observations, and documentation. The findings have shown that state defense education held by Bakesbangpol of Bandung City has shown changes in cognitive, affective and psychomotor aspects of the participants who take part in state defense education. This can be seen from the increase in capacity regarding membership, legal status, rights, and participation towards a better direction as a citizen. This is very important in realizing ideal citizens to support the achievement of state goals. This finding shows that it is important for Bakesbangpol to always carry out state defense education in a sustainable and programmed manner, by prioritizing aspects of innovation so that it always adapts to the times. For further research it is important to study with different methods, especially quantitative methods because it can determine the effect of political education on political education participants.
