Abstract

Penelitian ini bertujuan untuk mengetahui seberapa besar pengaruh product quality dan brand image terhadap purchase decision melalui lifestyle pada produk sepatu thrift impor di Kota Pekanbaru (Studi Kasus Mahasiswa di Kota Pekanbaru). Penelitian ini terdiri dari dua variabel independen yaitu product quality dan brand image dan satu variabel dependen yaitu purchase decision serta lifestyle sebagai variabel intervening. Metode analisis yang digunakan adalah analisis jalur. Metode pengumpulan data pada penelitian ini adalah dengan menggunakan kuesioner yang diisi oleh responden yaitu mahasiswa se kota Pekanbaru yang membeli produk sepatu thrift impor. Hasil penelitian yang didapatkan berdasarkan Uji Parsial (Uji t) diperoleh: a) terdapat pengaruh signifikan product quality terhadap lifestyle, b) terdapat  pengaruh signifikan brand image terhadap lifestyle, c) tidak terdapat pengaruh signifikan product quality terhadap purchase decision, d) terdapat pengaruh signifikan brand image terhadap purchase decision, e) tidak terdapat pengaruh signifikan lifestyle terhadap purchase decision, f) lifestyle tidak dapat memediasi pengaruh product quality terhadap purchase decision g) lifestyle tidak dapat memediasi pengaruh brand image terhadap purchase decision.

Abstract

This study aimed to improve the accuracy of determining the feasibility of evacuation posts after natural disasters using the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) within a Spatial Decision Support System (SDSS). A dataset of 50 evacuation posts from the 2021 Mount Semeru eruption was analyzed. The Rank Order Centroid (ROC) method was applied for criteria weighting, and TOPSIS was used to process the data. Results showed 72% accuracy, confirming that TOPSIS is a passable method for assessing post-feasibility based on accessibility, sanitation, and refugee facilities. Although the focus is on evaluating post-disaster evacuation posts, the system can be adapted for use in various other types of disasters. However, it is still dependent on historical data and lacks real-time adaptability. Future research can integrate Artificial Intelligence (AI) and Machine Learning (ML) with real-time data to improve decision-making in disaster management.
