Abstract

Organizational Identity (OI) as part of organizational culture refers to Organizational Change in organizational characteristics which in the eyes of its members are the center of the organization's character or "self-image". These characteristics distinguish the organization from other organizations of similar nature, and are seen as having continuity, especially towards the current era of disruption. The concept of organizational identity (OI) is of great interest to researchers for the simple reason that OI fits well with those who work in organizations. In the context of dynamic organizational transition in the era of disruption with artificial intelligence, OI has a very strong relationship. This study aims to conduct a systematic literature review on anthropomorphized organizational identity to offer new and important insights into how organizations engage organizational members to think, feel, and behave; unique organizational character, and the target of anthropomorphism will have a very significant impact, especially with the presence of artificial intelligence Researchers are able to carry out in-depth analysis and arrive at definite results because the data is obtained from academic publications and books containing references to organizational identity and organizational culture in the era of disruption.

Abstract

Pandemi Covid-19 berdampak pada produktivitas masyarakat dan kondisi perekonomian. Meningkatnya penggunaan media online di masa pandemi berdampak pada sektor teknologi dan ekonomi dimana semakin banyak investor yang berinvestasi di industri teknologi. Harga indeks saham sektor teknologi cenderung meningkat. Penelitian ini menggunakan analisis time series pada perusahaan subsektor teknologi dengan menggunakan data historis. Harga saham ini diperoleh dari www.investing.com yang diterbitkan oleh idx. hasil penelitian ini menunjukkan bahwa data indeks harga saham mingguan subsektor periode 2021 sampai dengan 2022 bersifat heteroskedastis dan terdapat fluktuasi yang tidak simetris, sehingga diperlukan variasi model arch/garch yaitu arch (1,0) to menghasilkan hasil peramalan yang akurat. Hasil peramalan model ini menunjukkan bahwa model arch (1.0) cukup akurat dalam melakukan peramalan dengan rata-rata persentase kesalahan mutlak sebesar 0,0038%. Indeks saham sektor teknologi dipengaruhi oleh beberapa faktor, baik ekonomi mikro maupun ekonomi makro.
