Abstract

Living in an information era, the presence of data is super important. With the data exponentially grows from decades to decades, it reflect the old saying that people today are so rich with data yet so poor on information. To dissect the information that contained within the large amount of data, a method is introduced called “Data Mining.” Data mining is a process of retriving a unique, unseen, and valuable information/insight from the data. Data mining comes with a lot of methods branches, one of those is pattern analysis, or also known as “Association Rules”. With the help of Association Rules, people can discover the relational pattern within the data, so people can make the best decision on the period of time. In this study, the writer is implementing Apriori Algorithm (one of the Association Rules algorithm) to see the pattern of a polyclinic visitor.

Abstract

Fingerprint authentication has been extensively employed as a biometric method in diverse applications, including smartphones and embedded systems. Despite its advantages, this technology is susceptible to spoofing attacks using materials such as gelatin, posing a significant security risk. Numerous solutions have been proposed, but deep learning-based approaches often face challenges due to their large model sizes, limiting deployment in resource-constrained environments. To address this issue, we developed a lightweight and efficient fingerprint liveness detection model by integrating wavelet-attention with inverted-bottleneck convolution. The proposed method balances computational efficiency with high accuracy, enabling its practical implementation on low-resource devices.The model was designed with only 874,000 parameters and a memory footprint of 4 MB, representing a significant reduction in size compared to conventional deep learning models. The use of wavelet-attention enhances feature extraction by focusing on multi-scale spatial details crucial for distinguishing live and spoof fingerprints. Extensive experiments were conducted on the LivDet dataset and a custom dataset, encompassing fingerprints captured from multiple sensors.The results demonstrated robust performance, achieving an average classification error (ACE) of 2.27 across various sensors, which is competitive with state-of-the-art methods. Additionally, the model exhibited consistent performance in scenarios with limited computational resources, highlighting its efficiency and scalability.These findings suggest that the proposed approach is a viable solution for enhancing the reliability of fingerprint liveness detection, particularly in applications requiring lightweight and resource-efficient models.

Abstract

Koperasi Simpan Pinjam (KSP) memiliki peran vital dalam memperluas akses layanan keuangan masyarakat Indonesia. Namun, sistem pencatatan manual yang masih banyak digunakan menyebabkan berbagai kendala, seperti rendahnya efisiensi operasional dan tingginya risiko kesalahan pencatatan. Penelitian ini bertujuan untuk mengembangkan Sistem Informasi Tabungan (SIT) dengan pendekatan metodologi Agile, yang memungkinkan tim pengembang merespons kebutuhan pengguna secara cepat dan fleksibel. Sistem ini dibangun menggunakan framework CodeIgniter dengan arsitektur Model-ViewController (MVC) dan memanfaatkan Bootstrap guna menghasilkan antarmuka yang responsif dan mudah digunakan. Evaluasi dilakukan melalui pengujian waktu pemrosesan, validasi fungsional menggunakan black-box testing, serta survei tingkat kepuasan pengguna. Hasil implementasi menunjukkan peningkatan efisiensi sebesar 72%, dengan waktu rata-rata 22,7 detik untuk transaksi dan 68,9 detik untuk pembuatan laporan bulanan. Pengujian fungsional terhadap lima modul utama mencatat tingkat akurasi 100%, sementara survei terhadap 45 pengguna menunjukkan skor kepuasan rata-rata 4,8 dari 5, berkat fitur pelacakan transaksi secara real-time yang meningkatkan transparansi.

Abstract

As a vocational higher education institution in the field of tourism, Politeknik Pariwisata Bali has an obligation to provide the public with access to information that is easy, fast, and accountable. This study discusses the implementation of the Public Information and Documentation Officer (PPID) as the main instrument to support information transparency at Politeknik Pariwisata Bali. The system was developed using the Waterfall method with PHP as the programming language and MySQL as the database. The testing process was carried out using the blackbox testing method to ensure that each system function operates as required. The implementation results show that the developed PPID system is capable of providing services for information requests, complaints, and public aspirations in a more effective and integrated manner.
