Abstract

Penelitian ini menganalisis pengaruh kualitas produk dan harga terhadap keputusan pembelian iPhone di kalangan mahasiswa, dengan citra merek sebagai variabel mediasi. Data dikumpulkan melalui kuesioner dari 240 mahasiswa di kota Kendari yang menggunakan iPhone, dan dianalisis menggunakan Structural Equation Modeling (SEM) dengan SmartPLS 3.0. Hasil menunjukkan kualitas produk berpengaruh positif signifikan terhadap citra merek dan keputusan pembelian. Sebaliknya, harga tidak berpengaruh signifikan terhadap citra merek maupun keputusan pembelian. Citra merek juga tidak berpengaruh positif signifikan dan bahkan memiliki hubungan negatif terhadap keputusan pembelian, serta tidak memediasi hubungan antara kualitas dan harga terhadap keputusan pembelian. Temuan ini mengindikasikan bahwa mahasiswa lebih mengutamakan aspek fungsional dan kualitas teknis dibandingkan citra merek dalam memilih iPhone. Secara praktis, produk premium perlu mengarahkan strategi pemasaran pada manfaat produk dan fleksibilitas harga untuk segmen yang belum memiliki kekuatan finansial secara konsisten. Penelitian ini juga menggeser anggapan bahwa citra merek selalu menjadi faktor utama dalam keputusan pembelian produk premium.

Abstract

This study examines the effect of upper management support on audit quality and auditor competence, as well as their impact on organizational performance, with extrinsic rewards as a moderating variable. Methods: This research employs a quantitative, explanatory design using a cross-sectional approach. The study was conducted on 240 auditors in Southeast Sulawesi using a census method. Data were collected through structured questionnaires measured on a five-point Likert scale and analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM). Results: The results show that upper management support has a positive and significant effect on audit quality and auditor competence. Furthermore, audit quality and auditor competence significantly influence organizational performance. However, extrinsic rewards do not moderate the relationships between audit quality and organizational performance, nor between auditor competence and organizational performance. Implications: These findings imply that organizational performance is more influenced by internal structural support and professional competence than external reward systems. Future research is suggested to explore other moderating variables to better explain performance improvement
