Abstract

Penyakit kardiovaskular masih menjadi penyebab kematian tertinggi di dunia sehingga pemeriksaan elektrokardiogram (EKG) menjadi bagian penting dalam proses diagnosis dan monitoring kondisi jantung. Keakuratan hasil pemeriksaan EKG sangat dipengaruhi oleh kualitas elektroda yang digunakan, termasuk aspek adhesi, kenyamanan, dan kualitas sinyal. Salah satu elektroda yang banyak digunakan adalah Ambu Bluesensor, namun penelitian mengenai persepsi pengguna terhadap kualitas produk ini masih terbatas. Penelitian ini bertujuan untuk mengeksplorasi persepsi pengguna terhadap kualitas elektroda ECG Ambu Bluesensor melalui pendekatan netnografi berbasis data digital. Penelitian menggunakan metode kualitatif dengan pendekatan netnografi terhadap ulasan pengguna pada platform e-commerce, forum kesehatan, media sosial, dan situs distributor alat kesehatan selama periode 2020–2024. Data dianalisis menggunakan analisis tematik berbantuan perangkat lunak NVivo 12 melalui tahapan coding, kategorisasi, dan interpretasi tema. Hasil penelitian menunjukkan bahwa persepsi pengguna didominasi oleh aspek teknis performansi seperti daya rekat dan kualitas sinyal, diikuti kenyamanan penggunaan, kualitas umum produk, serta layanan penjual. Pengguna menilai Ambu Bluesensor memiliki adhesi kuat, kualitas sinyal stabil, dan nyaman digunakan dalam berbagai konteks klinis. Penelitian ini menyimpulkan bahwa persepsi pengguna terhadap elektroda Ambu Bluesensor bersifat multidimensi dan dipengaruhi oleh kombinasi faktor teknis, pengalaman subjektif, serta konteks penggunaan produk.

Abstract

This study examines the impact of liquidity and leverage on profitability and firm value in oil and gas companies listed on the Indonesia Stock Exchange in 2024. The oil and gas sector plays a strategic role in Indonesia’s economy, yet it faces high financial risk due to fluctuating global oil prices, intensive capital requirements, and unstable market conditions. Therefore, understanding the relationship between liquidity, leverage, profitability, and firm value becomes important for investors and corporate management in making financial decisions. The purpose of this study is to analyse the direct and indirect effects of liquidity and leverage on profitability and firm value using profitability as an intervening variable. This research applied a quantitative causal-comparative approach using secondary data obtained from annual financial reports of oil and gas companies listed on the Indonesia Stock Exchange. The data were analyzed using Structural Equation Modeling–Partial Least Squares (SEM-PLS). The findings indicate that liquidity has a positive and significant effect on profitability, showing that companies with stronger liquidity are more capable of generating profits efficiently. In contrast, profitability has a negative and significant effect on firm value, indicating that increased profitability does not always improve market valuation. These findings suggest that investor perceptions, financial policies, and market conditions may influence firm value more strongly than profitability alone. The study concludes that financial performance and market valuation are not always directly aligned in the oil and gas sector
