Abstract

Modern reproductive technology advancements such as in vitro fertilization (IVF), gamete donation, surrogacy, and genetic engineering have brought significant changes to human reproduction practices, while also raising increasingly complex bioethical and theological issues.A gap in academic research is evident in the limited studies that comprehensively examine the bioethical and theological-normative dimensions when assessing the moral implications of these technologies.This study aims to analyze the bioethics of modern reproductive technologies from a theological-normative perspective and identify the ethical implications they produce.The study employs a qualitative approach with a library research design.Data is collected from various academic literature, journals, and other relevant sources, then analyzed using content analysis to examine the principles of bioethics and the theological perspectives related to modern reproductive technologies.The findings show that although these technologies offer solutions for infertile couples, there are significant ethical concerns regarding the status of embryos, clarity of lineage, and the commercialization of the human body.These findings highlight the tension between modern bioethical principles such as autonomy, beneficence, non-maleficence, andjustice, and theological values that emphasize the sanctity of life and human moral responsibility.The significance of this study lies in its effort to integrate scientific and theological approaches in developing a more comprehensive ethical framework.In conclusion, modern reproductive technologies need to be regulated within a balanced ethical framework to respect human dignity and align with theological values.

Abstract

Asuransi Indonesia pernah alami kegagalan besar (Jiwasraya 2020-an, Prolife diinvestigasi). Hal itu mempertegas pentingnya pengawasan ketat pada emiten asuransi di BEI, terutama yang berkapitalisasi kecil dan likuiditas timpang. Penelitian ini menerapkan Isolation Forest untuk mendeteksi anomali volume dan harga saham sektor asuransi IDX menggunakan data harian End-of-Day periode 2 Januari 2020 hingga 29 Mei 2026. Audit likuiditas meloloskan 14 dari 18 saham (77,8%) ke tahap pemodelan; 4 saham (LPGI, ASRM, LIFE, ABDA) dikeluarkan karena proporsi hari tanpa transaksi berlebihan. Tiga fitur, yaitu log return, rasio volume relatif terhadap MA-20, dan rentang intraday relatif, melatih model per saham dengan ambang anomali pada persentil ke-5; fitur keempat yang direncanakan, yaitu rasio ukuran transaksi, tidak dapat dihitung karena keterbatasan data. Model mengidentifikasi 1.036 hari anomali (rata-rata 5,0% per saham, akibat konstruksi ambang batas, bukan temuan independen). Triangulasi terhadap kalender peristiwa hanya mengonfirmasi 42 anomali (4,1%), sementara enam anomali paling ekstrem tidak berkaitan dengan peristiwa mana pun. Anomali didominasi pola idiosyncratic (97,5% dari hari beranomali) dibanding sector-wide (2,5%), dengan satu hari ekstrem (5 Januari 2026) mencatat keserentakan penuh pada seluruh 14 saham yang memerlukan verifikasi lanjutan. Temuan ini mendukung kelayakan Isolation Forest sebagai alat pemantauan awal bagi investor dan regulator, dengan batasan metodologis yang ditandai eksplisit. Anomalies were dominated by idiosyncratic patterns (97.5% of anomalous days) rather than sector-wide patterns (2.5%), with one extreme day (January 5, 2026) showing complete synchrony across all 14 stocks, which requires further verification. These findings support the viability of Isolation Forest as an early-warning monitoring tool for investors and regulators, with its methodological limitations explicitly noted.
