Abstract

The hotel industry in Batam continues to grow alongside the development of tourism and business sectors. Five-star hotel restaurants play an essential role in attracting consumers, particularly millennials and Generation Z, who prioritize experiential dining. This study aims to analyze the influence of promotion, brand image, and product quality on purchasing decisions at five-star hotel restaurants in Batam. This research applies a quantitative approach with an associative causal research design. A total of 100 respondents were selected using a nonprobability sampling technique with a convenience sampling approach. Data were collected through a Likert-scale questionnaire and analyzed using SPSS version 25, including validity testing, reliability testing, classical assumption testing, and multiple regression analysis. The findings indicate that promotion, brand image, and product quality have a positive and significant effect both partially and simultaneously on purchasing decisions. Product quality is identified as the most influential factor in purchasing decisions. The coefficient of determination (R²) value of 0.635 shows that the three variables explain 63.5% of the variance in purchase decisions. The study concludes that integrated marketing strategies supported by strong brand image and consistent product quality are essential to enhance consumer purchasing decisions in five-star hotel restaurants in Batam.

Abstract

Penelitian ini dilatarbelakangi oleh persaingan pasar kosmetik yang semakin ketat, khususnya di kota strategis seperti Batam, yang membuat pemahaman mengenai perilaku konsumen menjadi sangat krusial. Tujuan dari penelitian ini adalah untuk menganalisis secara mendalam dan komprehensif pengaruh tiga variabel utama—kualitas layanan, citra merek, dan kualitas produk—terhadap keputusan pembelian produk pelembab wajah merek Sariayu. Populasi dalam penelitian ini mencakup seluruh konsumen yang pernah membeli produk tersebut, yang jumlahnya besar dan tidak terbatas sehingga sulit diidentifikasi satu per satu. Oleh karena itu, metode purposive sampling dipilih secara sengaja untuk memastikan bahwa data yang dikumpulkan benar-benar berasal dari sasaran yang tepat, yaitu mereka yang telah memiliki pengalaman langsung dalam melakukan pembelian. Melalui sebaran kuisioner, penelitian berhasil mengumpulkan data primer dari 204 responden yang memenuhi kriteria. Data ini selanjutnya dianalisis menggunakan teknik analisis regresi linear berganda, sebuah alat statistik yang andal untuk mengukur sejauh mana variabel-variabel bebas secara bersama-sama (simultan) maupun secara terpisah (parsial) memengaruhi variabel terikat. Hasil penelitian secara meyakinkan menunjukkan bahwa kualitas layanan, citra merek, dan kualitas produk secara konsisten menunjukkan pengaruh positif yang signifikan terhadap keputusan pembelian konsumen. Tematan ini membawa implikasi strategis bahwa upaya peningkatan penjualan tidak bisa hanya mengandalkan satu aspek semata. Dari hasil tersebut, dapat disimpulkan bahwa untuk memenangkan pasar di Batam, Sariayu harus menerapkan strategi holistik: menyajikan layanan pelanggan yang prima, membangun citra merek yang positif dan terpercaya, serta menjaga komitmen terhadap produk berkualitas tinggi. Sinergi dari ketiga elemen ini merupakan kunci fundamental untuk mendorong dan meningkatkan keputusan pembelian secara berkelanjutan.
