Abstract

Digital platform markets have become a central infrastructure of Indonesia’s contemporary economy and transforming contemporary business relations by embedding contractual governance into algorithmic infrastructures. While platforms are commonly perceived as neutral intermediaries, many operate simultaneously as market organizers and competing economic actors. This dual role has facilitated self-preferencing practices, whereby platforms prioritize their own products or services through contractual discretion and algorithmic governance. Against this background, existing legal scholarship in Indonesia has predominantly examined self-preferencing from a competition law perspective, leaving its contractual dimensions and implications for MSME protection underexplored. Responding to this gap, this research employs a normative legal research method with a conceptual approach to analyze self-preferencing as a manifestation of contractual inequality in digital platform markets and examines platform contracts as instruments of private regulation within the Indonesian legal framework, particularly through the principles of freedom of contract, good faith, and contractual balance. The analysis finds that self-preferencing is structurally enabled by asymmetric platform contracts, which are predominantly drafted as standard form agreements. These contracts expose Indonesian MSMEs to economic dependence and market exclusion without any contractual breach. The article concludes that effective MSME protection in Indonesia requires a reformulation of contract law responses through strengthened good faith obligations, limits on unilateral contractual discretion, and explicit recognition of contractual inequality inherent in standard form platform contracts to ensure fairness, legal certainty, and sustainable digital market governance.
