Abstract

Penelitian ini bertujuan untuk menganalisis pengaruh Brand Awareness, Kepercayaan Konsumen, dan Strategi Konten Media Marketing terhadap Minat Pembelian Ulang pada pelanggan e-commerce Lazada di Kota Bandung. Latar belakang penelitian ini didasarkan pada persaingan industri e-commerce yang semakin ketat serta pentingnya membangun loyalitas pelanggan melalui penguatan kesadaran merek, kepercayaan, dan strategi konten digital. Penelitian menggunakan pendekatan kuantitatif dengan metode survei. Sampel penelitian berjumlah 100 responden yang dipilih menggunakan teknik purposive sampling dengan kriteria pernah melakukan pembelian di Lazada dalam enam bulan terakhir. Data dikumpulkan melalui kuesioner berskala Likert lima poin dan dianalisis menggunakan regresi linear berganda. Hasil penelitian menunjukkan bahwa Brand Awareness dan Kepercayaan Konsumen berpengaruh positif dan signifikan terhadap Minat Pembelian Ulang. Hal ini mengindikasikan bahwa semakin tinggi tingkat pengenalan merek dan kepercayaan terhadap layanan Lazada, maka semakin besar kemungkinan konsumen untuk kembali melakukan pembelian. Sementara itu, Strategi Konten Media Marketing secara parsial tidak berpengaruh signifikan terhadap Minat Pembelian Ulang, meskipun memiliki hubungan yang cukup kuat. Namun demikian, secara simultan ketiga variabel independen tersebut berpengaruh signifikan terhadap Minat Pembelian Ulang. Nilai koefisien determinasi sebesar 70,9% menunjukkan bahwa sebagian besar variasi Minat Pembelian Ulang dapat dijelaskan oleh model penelitian, sedangkan sisanya dipengaruhi oleh faktor lain di luar penelitian. Temuan ini menegaskan pentingnya penguatan brand awareness dan kepercayaan konsumen dalam meningkatkan loyalitas pelanggan pada platform e-commerce.

Abstract

Studi ini dilakukan guna menganalisis pengaruh Current Ratio (CR), Debt to Equity Ratio (DER), dan Net Profit Margin (NPM) terhadap tingkat Return On Asset (ROA) pada PT Sarimelati Kencana Tbk pada periode 2019-2024. Penelitian ini menggunakan pendekatan kuantitatif yang didasarkan pada metode analisis regresi linier berganda, dengan mengelola data sekunder yang bersumber dari laporan keuangan perusahaan. Selama periode pengamatan kinerja keuangan PT Sarimelati Kencana Tbk menunjukkan fluktuasi yang cukup signifikan akibat pandemi Covid-19 dan isu konflik pemboikotan yang memengaruhi aktivitas operasional, penjualan, serta persepsi pasar terhadap perusahaan. Penurunan Current Ratio (CR) dan Debt to Equity (DER) mencerminkan kondisi likuiditas dan solvabilitas yang kurang baik. Sedangkan ketidakstabilan Return On Asset (ROA) mengindikasikan bahwa kemampuan perusahaan dalam mengoptimalkan aktivitas penghasil laba belum berjalan secara konsisten. Pengujian secara parsial memperlihatkan variabel Current Ratio (CR) dan Debt to Equity (DER) tidak memberikan pengaruh terhadap Return On Asset (ROA), sementara Net Profit Margin (NPM) terbukti berpengaruh secara signifikan. Pengujian secara simultan melalui uji F bahwa ketiga variabel bebas secara bersama-sama memberikan pengaruh nyata terhadap Return On Asset (ROA). Hasil Koefisien determinasi mengindikasikan bahwa terdapat faktor-faktor diluar model yang masih berkonfribusi terhadap variasi ROA. Dengan demikian, hasil studi ini menyimpulkan bahwa tingkat profitabilitas perusahaan lebih ditentukan oleh efisiensi perolehan laba bersih dibandingkan likuiditas dan solvabilitas.

Abstract

This research examines the effect of liquidity, leverage, activity, and profitability on financial distress among manufacturing companies included in the LQ45 Index in Indonesia during 2020–2024. This research used a quantitative explanatory approach to investigate the relationship between the variables. The analysis relied on secondary data obtained from the audited annual reports of 7 manufacturing companies selected by purposive sampling method, resulting in a balanced panel dataset consisting of 35 observations. Financial distress was measured using the Altman Z-Score, while TATO, ROA, DER, and CR were employed as the independent variables. To evaluate both the individual and combined effects of these variables on financial distress, panel data regression analysis was conducted using the CEM, supported by t-test and F-test analysis. The results reveal that liquidity (t = 2.426; p = 0.022) and profitability (p = 0.070) have positive and statistically significant correlations with the Altman Z-Score, indicating that stronger liquidity and higher profitability mitigate financial distress risk, with profitability emerging as the dominant predictor. Conversely, leverage and asset efficiency show no significant individual effects, suggesting that manufacturing firms can adjust their capital structure and asset utilization without necessarily increasing financial distress risk. However, when all four ratios are considered simultaneously, they collectively explain a substantial portion of the variation in financial distress (F = 3.797; p = 0.013; R² = 33.61%). These findings highlight that financial ratio indicators, particularly those related to liquidity and profitability, are useful for evaluating the financial health of established manufacturing firms in Indonesia's LQ45 Index.

Abstract

Macroeconomic fluctuations are among the primary factors influencing stock price movements in the capital market. However, previous studies have reported inconsistent findings regarding the effects of inflation, interest rates, and exchange rates on LQ45 stock prices during the post-pandemic period, indicating the need for further empirical investigation. This study aims to examine the effects of inflation, interest rates, and exchange rates on the stock prices of companies listed in the LQ45 Index of the Indonesia Stock Exchange during 2020–2025. A quantitative approach was employed using secondary data obtained from the Indonesia Stock Exchange, Bank Indonesia, and Statistics Indonesia. The data were analyzed using multiple linear regression after satisfying the classical assumption tests. The results reveal that inflation has a significant negative effect on stock prices, while interest rates also exert a significant negative influence. Conversely, the exchange rate has a significant positive effect on stock prices. Simultaneously, these macroeconomic variables significantly affect stock prices, with an Adjusted R² of 66.6%, indicating that the proposed model explains a substantial proportion of stock price variation. These findings highlight the importance of macroeconomic stability in supporting capital market performance. The study provides practical implications for investors in developing investment strategies based on macroeconomic indicators and for policymakers in designing monetary and economic policies that promote market stability and strengthen investor confidence.

Abstract

Generation Z faces increasingly intense competition in the labor market; however, many individuals continue to encounter difficulties during job interviews due to limited experience, low self-confidence, and insufficient professional communication skills. This study aims to analyze the implementation of job interview simulations and examine their impact on the job readiness of Generation Z in Bandung City. The study employed a descriptive-evaluative method involving 45 Generation Z participants. Data were collected through observation, performance assessments, documentation, and participant feedback. The findings indicate that job interview simulations effectively enhanced participants’ readiness, as evidenced by 85% of participants reporting that they felt highly prepared and confident, while the remaining 15% reported feeling prepared and confident after completing the program. Interviewers’ evaluations revealed that 70% of participants demonstrated a very good improvement in their ability to respond to interview questions, 18% showed good improvement, and 12% exhibited fairly good improvement. Participant satisfaction with the program was also notably high, with 77% reporting being very satisfied, 15% satisfied, and 8% fairly satisfied with the implementation of the activity. The results confirm that job interview simulations are effective in improving participants’ self-confidence, communication competence, and overall job readiness. The novelty of this study lies in the application of interview simulations based on authentic recruitment scenarios, evaluated through the dimensions of job readiness, communication competence, and participant satisfaction, thereby offering a practical career development model for Generation Z.
