Abstract

This research investigates the effectiveness of the E-Catalog system in supporting goods and services procurement at Sesko TNI Bandung. As a digital procurement platform introduced by the government, the E-Catalog aims to increase transparency, accuracy, and process efficiency. Despite these intended advantages, its adoption remains constrained by users’ limited familiarity with digital procurement practices and their long-standing reliance on manual procedures. To address this issue, the study applies the Technology Acceptance Model (TAM) as the analytical framework, focusing on perceived usefulness, perceived ease of use, user attitudes, and behavioral intentions toward system utilization. A mixed-methods approach with a sequential explanatory design was employed. The quantitative phase involved distributing structured questionnaires to procurement personnel to measure key variables related to system acceptance. Subsequently, qualitative data were obtained through in-depth interviews with procurement operators to clarify and deepen the interpretation of statistical results. The study finds that perceived usefulness and perceived ease of use significantly shape user attitudes and intention to utilize the E-Catalog. These variables collectively contribute to improving the overall effectiveness of the procurement process. The results highlight that the more users perceive the system as beneficial and easy to operate, the more likely they are to adopt it consistently, thereby enhancing operational efficiency at Sesko TNI Bandung. This research underscores the importance of increasing digital literacy, strengthening system socialization, and providing continuous training to optimize the performance of the E-Catalog platform.

Abstract

Perkembangan teknologi informasi saat ini memberikan kemudahan bagi pelaku usaha dalam mengelola transaksi melalui penggunaan aplikasi Point of Sale (POS). Aplikasi ini mampu mencatat seluruh aktivitas penjualan, pembelian, laba rugi, rekap transaksi harian, bulanan hingga tahunan, serta data pelanggan, pemasok, dan catatan hutang piutang dalam satu sistem terintegrasi. Penelitian ini bertujuan untuk menganalisis efektivitas penerapan aplikasi POS dalam mendukung transparansi dan akurasi data transaksi pada Toko Plastik dan Bahan Kue Ganesha. Metode penelitian yang digunakan adalah deskriptif dengan pendekatan studi kasus, melalui observasi langsung dan wawancara terhadap pemilik usaha. Hasil penelitian menunjukkan bahwa penggunaan aplikasi POS membantu meningkatkan efisiensi pencatatan transaksi serta mempermudah pengambilan keputusan berbasis data. Namun, masih ditemukan beberapa kekurangan dalam hal pembaruan data dan sinkronisasi laporan yang perlu disempurnakan. Penelitian ini menyimpulkan bahwa aplikasi Griyo Pos efektif dalam membantu usaha mikro, kecil, dan menengah (UMKM) mengelola transaksi, stok, dan laporan keuangan secara terintegrasi, meskipun masih terdapat kelemahan pada pencatatan transaksi belum dibayar yang otomatis masuk ke dalam laporan penjualan harian sehingga menyebabkan selisih antara uang kas dan total penjualan. Oleh karena itu, direkomendasikan agar pembaruan aplikasi ke depannya menyediakan fitur terpisah untuk transaksi belum dibayar guna memudahkan pelacakan dan rekonsiliasi. Melalui pengelolaan data yang lebih baik, pelaku usaha dapat merancang strategi pengembangan usaha yang lebih tepat sasaran.
