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

RW 01 Cikudapateuh Dalam masih menggunakan metode konvensional dalam proses pendataan penduduk, seperti pencatatan manual melalui buku atau spreadsheet, yang menyebabkan keterlambatan pembaruan dan ketidaksesuaian data antara RT dan RW. Kondisi ini menjadi tantangan dalam menjaga akurasi serta efisiensi pengelolaan data kependudukan. Untuk mengatasi permasalahan tersebut, dilakukan perancangan dan pembangunan aplikasi pendataan penduduk berbasis Android yang dibangun untuk mempermudah pengurus RT dalam melakukan input dan pembaruan data, serta memungkinkan RW mengakses data dari seluruh RT secara real-time. Pengembangan aplikasi ini menggunakan metode Rapid Application Development (RAD) yang melibatkan tahapan analisis kebutuhan, perancangan, implementasi, dan evaluasi sistem secara cepat dan iteratif. Pengujian dilakukan menggunakan metode Black Box Testing untuk menguji fungsionalitas sistem, serta User Acceptance Test (UAT) untuk menilai tingkat kepuasan pengguna. Hasil pengujian menunjukkan bahwa aplikasi berjalan sesuai dengan kebu tuhan pengguna dan memiliki kualitas yang sangat baik, dengan rata-rata nilai pengujian aspek Functionality, Reliability, Usability, dan Efficiency sebesar 86,6% dalam kategori “Sangat Setuju”. Aplikasi ini dinilai efektif dalam mendukung digitalisasi admin istrasi kependudukan, meningkatkan efisiensi kerja pengurus RT dan RW, serta mempercepat proses penyesuaian dan pem baruan data secara akurat dan terintegrasi.
