<![CDATA[This research examines three fundamental aspects of Indonesian arbitration law arbitral awards, the enforcement of arbitral awards, and the annulment of arbitral awards based on Law Number 30 of 1999 concerning Arbitration and Alternative Dispute Resolution, as well as the latest regulatory development, Supreme Court Regulation (PERMA) Number 3 of 2023. The research employs a normative legal method using the statute approach, conceptual approach, and case approach, through an examination of two important decisions: the dispute between Pertamina and Karaha Bodas Company, and the dispute between Astro Nusantara and PT Ayunda Prima Mitra. The findings show that arbitral awards are final and binding, yet their enforcement both domestic and international still faces technical, procedural, and jurisdictional obstacles. The annulment of arbitral awards is only permitted on the limited grounds set out in Article 70 of Law No. 30 of 1999, although in judicial practice the scope of these grounds is often interpreted extensively. The issuance of PERMA No. 3 of 2023 provides new procedural certainty, particularly regarding the timeframe for granting exequatur, but has not yet fully resolved the problem of annulment petitions being misused as a tactic to delay execution. This research recommends amending Law No. 30 of 1999, strengthening the capacity of district court judges, and establishing sanctions against annulment petitions filed in bad faith, in order to enhance the effectiveness of arbitration as a means of resolving business disputes in Indonesia. If you'd like, I can also help refine this into a more formal academic-abstract register (e.g., adjusting terminology like "exequatur," "bad faith," or "annulment" to match standard usage in international arbitration literature) just let me know. Abstrak Penelitian ini mengkaji tiga aspek fundamental dalam hukum arbitrase Indonesia, yaitu putusan arbitrase, pelaksanaan putusan arbitrase, dan pembatalan putusan arbitrase, berdasarkan Undang-Undang Nomor 30 Tahun 1999 tentang Arbitrase dan Alternatif Penyelesaian Sengketa serta perkembangan regulasi terbaru, yakni Peraturan Mahkamah Agung Nomor 3 Tahun 2023. Penelitian menggunakan metode hukum normatif dengan pendekatan perundang-undangan (statute approach), pendekatan konseptual (conceptual approach), dan pendekatan kasus (case approach) melalui telaah dua putusan penting, yaitu sengketa Pertamina melawan Karaha Bodas Company dan sengketa Astro Nusantara melawan PT Ayunda Prima Mitra. Hasil kajian menunjukkan bahwa putusan arbitrase bersifat final dan mengikat, namun pelaksanaannya, baik domestik maupun internasional, masih menghadapi hambatan teknis, prosedural, dan yurisdiksional. Pembatalan putusan arbitrase hanya dimungkinkan atas dasar alasan limitatif dalam Pasal 70 UU No. 30 Tahun 1999, meskipun dalam praktik peradilan cakupan alasan tersebut kerap ditafsirkan secara ekstensif. Kehadiran PERMA No. 3 Tahun 2023 memberikan kepastian prosedural baru, terutama terkait jangka waktu pemberian exequatur, namun belum sepenuhnya menjawab persoalan penyalahgunaan permohonan pembatalan sebagai taktik penundaan eksekusi. Penelitian ini merekomendasikan pembaruan UU No. 30 Tahun 1999, penguatan kapasitas hakim pengadilan negeri, serta pengaturan sanksi terhadap permohonan pembatalan yang tidak beriktikad baik guna meningkatkan efektivitas arbitrase sebagai sarana penyelesaian sengketa bisnis di Indonesia ]]>
