PROBLEMATIKA WAKIL MENTERI DALAM KABINET MERAH PUTIHNIM.: 24203011092YuliastariauthorThis research is motivated by the phenomenon of the increasing number of deputy ministers in the cabinet, which has generated both pros and cons, particularly regarding the effectiveness of government performance, bureaucratic efficiency, and implications for the state budget. This study aims to analyze the existence of deputy ministers in the Indonesian government system from the perspective of good governance and Siyāsah Idāriyyah. The researcher also wants to discuss the efficiency and budgetary impacts of the government to implement spending efficiencies, including salaries, facilities, and operational costs for ministries and deputy ministers. The addition of deputy ministers automatically increases the burden of routine state expenditures, such as accommodation, secretariat transportation, staff, and security. Many governments now join the Red and White Cabinet solely for their own interests. This research uses qualitative methods with a normative and conceptual approach. Primary legal materials were obtained from laws and regulations relating to deputy ministers, specifically Article 17 of the 1945 Constitution and Law Number 39 of 2008 concerning State Ministries. The analysis was conducted by examining the alignment of the practice of appointing deputy ministers with the principles of good governance and the values of the Islamic Law (Siyāsah Idāriyyah), as well as the perspective of Imam Al-Mawardi's thoughts on the role of wazir in leadership in carrying out the mandate. Legal material was collected through a library study of relevant scientific literature, journals, books, and previous research. The results of the study indicate that, normatively, the existence of deputy ministers is justified as an effort to assist ministers in improving government effectiveness. However, in practice, the existence of deputy ministers is not fully aligned with the principles of good governance, particularly in terms of efficiency, accountability, and clarity of authority. Increasing the number of deputy ministers has the potential to lead to overlapping functions, complex coordination, and an increase in the state budget. From the perspective of the Islamic Law (Siyāsah Idāriyyah), governance must be based on the principles of trustworthiness, efficiency, justice, and publik welfare. Therefore, the existence of positions that do not provide tangible benefits and actually increase the fiscal burden is deemed inconsistent with these principles.342 Hukum Tata Negara2026-05-21UIN SUNAN KALIJAGA YOGYAKARTA;FAKULTAS SYARIAH DAN HUKUMThesis
