The background of this study is the importance of the validity of land buying and selling that is carried out not in front of the Land Deed Making Officer (PPAT), especially because many people still buy and sell land under their hands. This practice is often caused by a lack of understanding of legal procedures or avoiding unwanted additional costs. In fact, in accordance with government regulations and applicable laws, the transfer of land rights can only be registered with proof of an authentic deed made by PPAT. Therefore, this study aims to analyze public sentiment towards #KawalPutusanMK hashtags on social media X (Twitter), using a netnography approach and big data analysis. The #KawalPutusanMK movement emerged in response to the DPR's efforts to revise the Constitutional Court's (MK) decision regarding the 2024 Regional Elections, which sparked controversy among the public. The research data was taken from conversations that occurred on platform X between August 21 and September 29, 2024. The results of the analysis showed that there were 1127 tweets using the hashtag, with the following sentiment distribution: 91 positive, 484 negative, and 552 neutral. The dominance of negative sentiment indicates public dissatisfaction with the Constitutional Court's decision. This research contributes to understanding the pattern of political communication on social media and provides insights for the government in monitoring public opinion and formulating more responsive policies.xx.
