Abstract

Audit kepuasan pelanggan internal merupakan fungsi penilaian independen yang penting bagi perusahaan ritel untuk menjaga konsistensi kualitas layanan di seluruh jaringan toko. PT XYZ memiliki 210 toko di Indonesia dan secara rutin melaksanakan audit berbasis web. Namun, Supervisor Toko masih mengalami kesulitan dalam menentukan prioritas pelatihan dan evaluasi karena belum mengetahui parameter checklist mana yang paling berpengaruh terhadap penurunan final score toko. Penelitian ini bertujuan membangun model klasterisasi toko berdasarkan karakteristik parameter checklist bernilai rendah dengan algoritma BIRCH. Dataset penelitian berjumlah 109.566 data audit tahun 2025 yang berasal dari sistem internal perusahaan. Metode penelitian mengikuti kerangka CRISP-DM yang meliputi Business Understanding, Data Understanding, Data Preparation, Modeling, Evaluation, dan Deployment. Tahap preprocessing mencakup data cleaning, data selection, data transformation, serta normalisasi Z-Score agar data siap diproses. Proses modeling menggunakan CF-Tree dengan parameter Branching Factor B dan Threshold T yang dimodifikasi secara dinamis untuk meningkatkan kualitas cluster. Evaluasi cluster dilakukan menggunakan Silhouette Coefficient. Hasil penelitian menunjukkan terbentuk 2 cluster optimal dari CF4 dan CF5 dengan nilai SC Cluster 1 sebesar 0,9994, SC Cluster 2 sebesar 0,9988, dan SC Global sebesar 0,9989. Hasil ini menunjukkan struktur cluster yang sangat kuat dan valid. Sistem berbasis Python juga berhasil menampilkan visualisasi scatter plot sebagai dasar pengambilan keputusan evaluasi kinerja karyawan.

Abstract

This study aims to analyze the dynamics of Generation Z's financial behavior in the digital era by examining the influence of QRIS availability, financial knowledge, savings and loan instruments, and investments on impulsive and rational spending. Using regression analysis, the results show that the ease of transactions through QRIS creates a behavioral paradox, where this system significantly encourages impulsive spending (55% of the variation in impulsivity is explained by QRIS use) while simultaneously weakening rational spending control.The research findings confirm that financial knowledge serves as a vital cognitive control mechanism; high financial literacy is negatively correlated with impulsive spending and positively correlated with rational spending. Furthermore, this study reveals the dual impact of owning financial instruments (savings and loans), which can trigger impulsive consumption if viewed solely as liquidity, but can foster rationality when managed within a future planning framework. Investments prove to be the most effective strategic instrument in curbing impulsive behavior, by shifting Generation Z's paradigm from viewing money as a consumptive medium of exchange to a long-term asset of value. Overall, this study concludes that the efficiency of digital payment technology requires mature financial literacy and investment discipline to prevent a shift in consumption patterns to unplanned ones.Keywords:  QRIS, Impulsive Spending, Rational Spending, Financial Knowledge, Generation Z, Investment.
