"Mekanisme persidangan in absentia dalam hukum acara pidana di Indonesia dirancang
untuk menjamin keberlangsungan proses hukum meskipun terdakwa tidak hadir di
persidangan. Skripsi ini mengkaji penerapan mekanisme in absentia terhadap tindak
pidana white collar crime dengan fokus pada tiga kasus, yakni Sherny Kojongian,
Hartawan Aluwi, dan Djoko Tjandra. Penelitian ini bertujuan untuk menjawab tiga
rumusan masalah: bagaimana pengaturan hukum terkait in absentia, bagaimana
penerapan mekanisme ini pada kasus-kasus white collar crime, serta apa saja kendala
yang dihadapi dalam pelaksanaan eksekusi putusan in absentia terhadap terdakwa yang
berstatus Interpol Red Notice. Penelitian ini menggunakan metode yuridis normatif
dengan pendekatan perundang-undangan dan studi kasus. Data dikumpulkan melalui
studi kepustakaan, termasuk peraturan perundang-undangan, dokumen kasus, dan
literatur yang relevan. Analisis dilakukan secara deskriptif-analitis untuk mengevaluasi
pengaturan normatif, praktik penerapan, serta kendala dan solusi terkait mekanisme in
absentia. Hasil penelitian menunjukkan bahwa pengaturan hukum acara pidana di
Indonesia telah mengakomodasi mekanisme in absentia untuk memberikan kepastian
hukum dalam penanganan kasus white collar crime. Mekanisme ini memungkinkan
pengadilan untuk menjatuhkan putusan tanpa kehadiran terdakwa, namun efektivitasnya
sangat bergantung pada koordinasi lintas negara melalui instrumen seperti Interpol Red
Notice. Kendala utama dalam eksekusi putusan meliputi kurangnya harmonisasi hukum
internasional, lemahnya penegakan Red Notice di negara pelarian terdakwa, serta
prosedur ekstradisi yang lambat. Sebagai simpulan, mekanisme in absentia dan Red
Notice memiliki peran strategis dalam penanganan white collar crime, namun
memerlukan penguatan koordinasi antarnegara. Rekomendasi penelitian ini mencakup
harmonisasi pengaturan in absentia dalam KUHAP dengan peraturan pelaksana,
optimalisasi perjanjian ekstradisi, penerapan Mutual Legal Assistance secara efektif, dan
peningkatan sinergi antara sistem hukum domestik dan internasional untuk meningkatkan
efektivitas eksekusi putusan.
The in absentia mechanism in the Indonesian legal system is designed to ensure the continuity of legal proceedings against absent defendants, particularly in white collar crime cases such as corruption and money laundering. This study analyses the application of in absentia in three cases-Sherny Kojongian, Hartawan Aluwi, and Djoko Tjandra-with a focus on its correlation with the issuance of Red Notice and its effect on the execution of verdicts and asset recovery. In all three cases, in absentia provides legal certainty to continue the judicial process without the presence of the defendant, while the Red Notice serves as an instrument to designate the defendant as an international fugitive. However, the correlation between the two suggests that the successful application of in absentia relies heavily on the effectiveness of the Red Notice in ensuring the defendant can be apprehended and extradited. Obstacles arise when the defendant's country of flight does not act on the Red Notice, as in the Sherny and Djoko cases, or when cross-border legal procedures slow down the extradition process, as in the Sherny and Djoko cases, or when cross-border legal procedures slow down the extradition process, as in the Hartawan case. In addition, delays in the implementation of in absentia or Red Notice also worsen the handling of cases because they prolong the escape of the accused and hinder the recovery of assets. This research confirms that although in absentia and Red Notice are important elements in international law enforcement, weaknesses in cross-border coordination and legal harmonisation remain key challenges. Therefore, strengthening extradition treaties, optimising Mutual Legal Assistance, and synergy between domestic and international systems are needed to support the effectiveness of both mechanisms. "
