Abstract

Teknologi digital saat ini berkembang dengan sangat cepat, apalagi di sektor e-commerce. Karena persaingan ketat di era disrupsi ini, Studi ini mengeksplorasi konsep e-commerce dari perspektif syariah, dengan fokus pada definisi, operasi bisnis, dan pengakuan dalam bisnis Islam. Ini mengungkapkan bahwa e-commerce adalah sistem perdagangan yang melibatkan perangkat elektronik untuk belanja online, menyoroti kebutuhan perusahaan untuk menemukan strategi bertahan hidup baru.Kecuali untuk barang yang dianggap sebagai objek jual-beli, jual-beli e-commerce pada dasarnya tidak berbeda dengan jual-beli as-salam. Jika Anda melakukan jual-beli e-commerce, Anda harus waspada, seperti memeriksa sistem keamanan perusahaan dan memahami apa yang Anda beli untuk menghindari membeli produk yang tidak berkualitas.

Abstract

Semiconductors underpin the digital economy, yet the memory market is highly cyclical, exposing chipmakers to sharp margin compression during oversupply and price corrections. This study examines SK hynix’s “extreme recovery” using Net Profit Margin (NPM) as the focal performance metric and interprets the recovery through cost-management theory, cost–volume–profit logic, and Activity-Based Costing (ABC). Adopting a quantitative descriptive design with a single-case study approach, the analysis relies on publicly available SK hynix financial statements from 2020–2024. Key variables include NPM (net income/revenue), revenue, and operating expenses; descriptive statistics, trend and percentage-change analysis, and Excel-based visualizations are complemented by triangulation with industry news. Results reveal a pronounced V-shape: NPM declined from 22.36% (2021) to 5.02% (2022) and −27.88% (2023), then rebounded to 29.9% (2024). The turnaround aligns with a higher-value product mix (AI HBM) and cost control, offering implications for investors and industrial policy.
