Analysis of Legal Protection Concepts for Workers in the Informal Sector Based on Indonesian Laws and Regulations: Analisis Konsep Perlindungan Hukum Terhadap Pekerja di Sektor Informal Berdasarkan Ketentuan Peraturan Perundang-Undangan di Indonesia
No full textGeneral Background: Informal sector workers play a crucial role in Indonesia’s labor market yet remain highly vulnerable due to limited legal protection. Specific Background: Existing regulations—including the Manpower Act, Job Creation Law, BPJS Law, and Government Regulation No. 35/2021—primarily regulate formal employment, leaving informal workers without explicit safeguards. Knowledge Gap: Despite their dominant share in the workforce, the normative framework insufficiently addresses the unique characteristics of informal employment and the widespread misclassification practices used to avoid employers’ legal obligations. Aims: This study analyzes the legal concept of protection for informal workers and evaluates how judicial reasoning in Supreme Court Decision No. 1049 K/Pdt.Sus-PHI/2023 reinforces such protection. Results: Findings indicate fragmented regulations that normatively recognize worker rights but fail to provide comprehensive operational mechanisms, requiring judicial interpretation to uphold substantive justice. Novelty: This study highlights how the Supreme Court’s substantive approach—affirming factual employment elements over formal documentation—fills normative gaps and corrects lower-court formalism. Implications: Strengthening explicit legal recognition of informal workers, enforcing BPJS obligations, and standardizing judicial tests for employment status are essential to ensure equitable and inclusive labor protection in Indonesia.
Highlights:
The legal framework for informal workers remains fragmented and insufficient.
The Supreme Court prioritizes factual employment elements over formal documents.

Political Dynasties Undermine Democratic Governance and Constitutional Integrity in Indonesia: Dinasti Politik Melemahkan Tata Kelola Demokratis dan Integritas Konstitusional di Indonesia
No full textPolitical dynasties represent a systemic challenge to Indonesia’s constitutional democracy by consolidating hereditary power that contradicts the principles of meritocracy, equal political access, and institutional accountability. This research aims to analyze how political dynasties distort democratic governance and weaken constitutional mechanisms that safeguard state integrity. Using a library research method supported by systematic content analysis of academic literature, legal sources, and policy documents, the study finds that dynastic politics institutionalize oligarchic power structures, suppress competitive leadership regeneration, and increase risks of corruption, collusion, and nepotism. The findings demonstrate that dynastic networks interfere with the separation of powers, politicize public resource allocation, bias representative functions toward familial interests, and reduce institutional autonomy within the constitutional framework. Although dynasties may provide policy continuity in certain contexts, these advantages are conditional and outweighed by structural threats to legal integrity and public trust. The novelty of this study lies in extending the discussion from electoral and regional governance to the broader constitutional domain, characterizing dynastic politics as a constitutional disruption rather than merely a political phenomenon. The implications suggest the need for transparent political recruitment, regulatory restrictions on hereditary candidacy, enhanced oversight mechanisms, and civic education to reinforce democratic resilience. These measures are essential to prevent the normalization of hereditary power and to protect constitutional democracy in Indonesia from long-term institutional degradation.
Highlights
• Political dynasties weaken constitutional accountability and democratic governance• Hereditary power restricts leadership succession and public institutional autonomy• Oligarchic networks increase corruption risks and distort public representation
