INTRODUCTION
Entering the digital era, the role of the internet and social media is increasingly popular among people of all ages. The social media development factor is also driven by the growth of increasingly sophisticated smartphones. Social media that are growing and developing rapidly at this time are TikTok, Instagram, Twitter, Facebook, Line, Telegram, and so on.

The millennial generation, also known as generation Y, is the generation born after generation X, namely the generation born around the 1980s to 1990s. (Nour Aldeen et al., 2022). Millennials are Indonesian citizens aged between 20 and 35 years (Subagyo et al., 2022). Millennials are getting used to using fast and easy technology, such as sending messages using WhatsApp, watching movies or videos on YouTube, or even sending important files via email. So that generation Y began to get rid of the methods used by generation X in sending information.
According to the Central Statistics Agency (BPS) in 2020, the number of millennials reached 69.38 million people or around 25.87% of Indonesia's population. The large population of the millennial generation is very important considering their strategic role as the successor to the development of the Indonesian nation.

RESEARCH METHOD
This study uses hypothesis testing. Hypothesis testing is a method that aims to test hypotheses which generally explain the relationships and differences between variables (Sekaran & Bougie, 2016). The unit of analysis used in this study is the individual. The population in this study are millennial-aged individuals who use social media to engage in SINOMICS JOURNAL | VOLUME 1 ISSUE 6 (2023) WWW.SINOMICSJOURNAL.COM 921

politics. The data from this study are cross-sectional data where the data obtained is only in a predetermined time and period. The data used in this study is primary data, namely data obtained and collected directly from individuals or respondents. There are five variables in this research, namely information quality of social media, reputation of social media, trust, use of social media and political involvement with 24 question items in this research questionnaire. The information quality of social media variable consists of 3 question items. The reputation of social media variable consists of 4 question items, the trust variable consists of 4 question items, political involvement consists of 6 questions. Questions from these four variables refer to research (Hamid et al., 2022). The use of social media variable consists of 7 question items that refer to research (Turan & Kara, 2018).
Determining the number of samples in this study refers to opinion (Hair et al., 2019), namely the number of question indicators multiplied by five to ten. Based on these guidelines, the minimum sample size in this study is 120 respondents. However, after being collected there were as many as 160 sample responses. After screening, only 130 were valid and could be used to continue the analysis in this study.

RESULTS AND DISCUSSION
There were 130 respondents who met the criteria of this study, which can be seen in table 1. It is known that the respondents who filled out the questionnaire consisted of 81 female respondents (62.3%) and 49 male respondents (37.7%). . Based on the duration of time spent using social media, 42 respondents (32.3%) spend 3 hours per day using social media. The most frequently used type of social media is Instagram, which consists of 54 respondents (41.5%).

Validity test
According to (Sekaran & Bougie, 2016) validity test is used to test the accuracy of the instrument in measuring the variables that the author will examine. The aim is to obtain a strength level of 80 percent, a significance level of 0.05 and the proposed inflation from standard errors of factor loadings (Hair et al., 2019). The required sample size for each factor

Reliability test
According to (Sekaran & Bougie, 2016) the reliability test is related to internal consistency between indicators used in measuring a variable. The reliability test in this study was carried out using Cronbach's Alpha, which is a test to see the level of consistency between question items, the higher the Cronbach's Alpha coefficient, the more homogeneous the items are in measuring a variable. A research instrument is said to be reliable if the Cronbach's Alpha value is > 0.60 (Ghozali, 2016). Can be seen in table 2. Source: data processed using SPSS.
Hypothesis testing uses Structural Equation Model (SEM) analysis with the AMOS program. SEM is an analytical method that allows testing of complex variable associations simultaneously. The research model can be seen in Figure 2.

RESULTS AND DISCUSSION
Goodness of fit shows how well the model made by researchers mathematically between indicator items (Hair et al., 2019). The decision making on the goodness of fit test is that the closer the value is between the indicators and the criteria (out of value), the better the model is and it can be said to be fit. Can be seen in table 3.  Source: data processed using AMOS Based on table 4, it can be seen that the first hypothesis has a positive influence between the information quality of social media on the reputation of social media, resulting in a positive estimate value of 1.228 and a p-value of 0.000 which indicates that H1 is accepted. Moreover, these results are similar to research (Hamid et al., 2022).
The second hypothesis is that there is a positive influence between the reputation of social media on trust, resulting in a positive estimate value of 1.123 and a p-value of 0.000 which indicates H2 is accepted. This finding is in line with research conducted (Tri et al., 2018) reputation has a significant effect on trust.
The third hypothesis is that there is a positive influence between trust and proven political involvement and H3 is accepted. The results of the research estimate value between these two variables show a positive number of 1.211 and a p-value of 0.000. The results of this study are in accordance with research (Akhrani et al., 2018) where there is a significant relationship between trust and political involvement, the higher political trust, the higher a person's political involvement. This research is also supported by research (Munawarah & Kristanto, 2022) The fourth hypothesis is that there is a positive influence between the information quality of social media and the use of social media. This hypothesis is proven because it is supported by research results which show that the estimate value is positive 0.931 and the pvalue is 0.000. The results of this study are supported by research (Aini & Nanda, 2020).
The fifth hypothesis is that there is a positive influence between the use of social media on political involvement resulting in a positive estimate value of 0.424 and a p-value of 0.022 which indicates H5 is accepted. These results are in accordance with previous research conducted by (Dwitama et al., 2022). In his research, he stated that the use of social media is an important instrument for influencing people's political involvement.

who stated that there is an influence between information quality of social media on political involvement. This study also attempts to reexamine and include the "use of social media" variable as the mediating variable. The main objective of this research is to examine the political involvement of millennials with the use of social media. This research has several limitations. First, this research is homogeneous, or only focuses on one research object, namely millennials. Further researchers need to consider using a larger and more diverse sample. Second, this research only focuses on generation Y, but the respondents are not only generation Y. Therefore, future research should include other generations such as generation X or generation Z. Third, this research only focuses on Indonesia, therefore further researchers are advised to expand research to other countries. Fourth, theories about the use of social media as political engagement are still quite limited.
