Abstract

Tujuan dari penelitian ini adalah menghasilkan rekomendasi kategori promosi yang dapat membantu pengambil keputusan dalam menentukan kategori promosi produk untuk meningkatkan jumlah penjualan. Pemilihan kategori promosi didasarkan pada tiga kriteria aspek, yaitu modal, penjualan, dan waktu. Data barang yang digunakan dalam sistem pendukung keputusan ini terdiri dari 119 item data. Metode profile matching penelitian pada kategori promosi menghasilkan 70 data untuk kategori raffiction, 25 untuk kategori mailer, 15 untuk kategori diskon, dan 9 untuk kategori listing. Black Box dan UAT (User Acceptance Test) adalah metode pengujian untuk penelitian ini. Hasil uji black box dibagi menjadi 15 kasus uji dan diperoleh hasil 100% sesuai dengan yang diharapkan. Hasil uji UAT berdasarkan persentase tiga aspek yaitu user-friendly 92%, fungsional 86,66%, dan layanan informasi 85%. Rata-rata pengujian UAT ketiga aspek tersebut adalah 87,88% Kata kunci: Sistem Pendukung Keputusan, Pencocokan Profil, Kategori Promosi, Black Box, UAT.

Abstract

The education management information system (MIS) must support educational activities. Both are interrelated and need each other. Payment of Educational Development Assistance (BPP) at SMA Negeri 5 Kupang is currently still done manually. This makes it difficult for officers to manage data related to the BPP payment process. Officers must carry out several recording processes in each payment transaction. The purpose of this community service activity is to improve the efficiency and accuracy of BPP payment management at SMA Negeri 5 Kupang. The implementation of this community service activity is divided into several stages, namely needs analysis (observation, interviews and data exploration on the internet), system design (design, coding and testing), implementation and training. This Community Service Activity produces a website-based payment information system that has three menus, namely the admin login menu, student login and payment. The system created can manage financial data and produce reports quickly and accurately and increase transparency and accountability in BPP management. The results of the system test using the blackbox method on buttons, menus, and various inputs to the system showed that all system processes run as they should or 100% run normally.

Abstract

Cryptography is the science of information security which is the most fundamental basic issue in ensuring the security of data transmission via the web. Cryptography works by transforming data or information into random form. Video data is the most widely accessed information medium because video conveys information in audio and visual form. In this study, cryptography was carried out on AVI video files with a combination of Beaufort and Vigenere substitution cipher algorithms using the RC4 key generator. Testing was carried out on three groups of video sample test data based on the size of the video file, where each group contained 10 video files. The test results obtained an average time required for encryption of 17 minutes 17 seconds, decryption of 17 minutes 40 seconds. The quality is indicated by the algorithm, namely from data integrity with an MSE value of 0 and a PSNR value of infinte, from the resulting cipher having an average value of MSE ± 15883 and PSNR ± 0.612 dB on audio, and an average value of MSE ± 14173 and PSNR ± 0.674 dB on frames. Resolution and video file size as well as initial key length do not significantly affect MSE and PSNR values. Statistically, the frequency range of color appearance in the histogram of cipher frames becomes narrower and relatively uniform. Waves in the audio cipher against time units move irregularly with changing sound level amplitudes and are relatively uniform in each audio sample. The resistance of the cipher to attacks is proven by the audio in three groups giving an average MSE of ± 16074 and PSNR of ± 0.607 dB, while for frames in three groups giving an average MSE of ± 15941 and PSNR of ± 0.623 dB.

Abstract

One aspect frequently posing a challenge in cryptography pertains to the length of the secret key that users must remember. Achieving the requisite key length for cryptographic algorithms necessitates key padding. However, it is crucial to note that key padding is susceptible to predictable patterns. Both the Linear Congruential Generator (LCG) and gray code are algorithms employed to generate sequences of padded key bits. Regrettably, LCG requires the determination of two pre-defined parameters, whereas the Auto Parameters Linear Congruential Generator (APLCG) automatically establishes these parameters. These parameters play a pivotal role in generating unique sequences of random integers. To fortify key security, the generation of new keys is performed using a modified logistic map, an enhancement of the standard logistic map that exhibits random behavior consistently. Stream cipher, an encryption algorithm, necessitates a continuous key stream matching the bit or byte length of the message. We conducted experiments on stream cipher algorithms employing key streams generated from APLCG, gray code, and modified logistic map. Twenty text documents were utilized as test samples. The outcomes indicate that stream ciphers employing APLCG, gray code, and modified logistic map demonstrate high-security performance based on the statistical analysis conducted.

Abstract

ABSTRAK - Digitalisasi adalah sasaran pergerakan dan perubahan zaman. Kondisi ini makin terasa pada era generasi milenial saat ini. Salah satu dampaknya adalah tren penggunaan teknologi informasi dan komunikasi seperti internet dan media sosial makin menjadi kebutuhan utama. Fenomena ini melanda hampir semua institusi masyarakat termasuk gereja. Hal serupa terjadi juga di jemaat Gereja Masehi Injili di Timor (GMIT) Koinonia Kupang yang persentase jemaatnya didominasi generasi milenial. Dampaknya adalah diperlukan model-model pelayanan yang menjangkau dan menjembatani kebutuhan jemaat yang berbasis teknologi informasi dan komunikasi (TIK). Solusi yang ditawarkan untuk masalah di atas adalah membuat website Gereja Koinonia sebagai sarana informasi dan komunikasi pelayanan gereja ke jemaat. Jemaat dapat mengakses informasi pelayanan kapan saja dan dimana saja menggunakan perangkat laptop atau smartphone. Selain itu dengan mengetahui informasi pelayanan memungkinkan anggota jemaat melibatkan diri dalam pelayanan gereja. Website koinonia juga memuat tabloid pelayanan online yang memuat secara rinci informasi kegiatan badan/unit dan lingkungan pelayanan dalam lingkup Jemaat Koinonia Kupang. Jemaat pun dapat memantau data statistik jemaat melalui database jemaat online pada website koinonia.
