not been optimally implemented. This study implements the 128-bit Advanced Encryption Standard (AES) algorithm combined with Huffman compression to protect the confidentiality and integrity of student grade files in Excel (.xlsx) format, and evaluates its effectiveness through functional, performance, and security testing. The system was developed as a Python desktop application with a CustomTkinter interface, in which the encryption process runs Huffman compression before AES-128, while integrity verification uses SHA-256 hashing. Testing was conducted on seven student grade files from MA Ma'ahid Kudus. The results show that all files were successfully encrypted and decrypted without failure or data alteration, with encryption times of 0.0142-0.0828 seconds and decryption times of 0.0046-0.1417 seconds. The SHA-256 hash values of the original and decrypted files were identical for all samples, yielding 100% recovery accuracy, while the file size increase from padding and header insertion ranged only from 1,092 to 1,101 bytes. The study concludes that the combination of AES-128 and Huffman compression is an effective and efficient solution for protecting student grade data in educational institutions.

, dan simbol. Penelitian ini menggunakan metode deskriptif kualitatif dengan teknik pengumpulan data berupa observasi, wawancara, dokumentasi, dan studi kepustakaan. Lokasi penelitian dilakukan di Gereja Katolik Paroki Santa Maria Fatima Betun, Kabupaten Malaka, Nusa Tenggara Timur. Hasil penelitian menunjukkan bahwa warna-warna liturgi seperti putih, kuning/emas, merah, hijau, ungu, merah muda, dan hitam memiliki makna simbolik yang mendalam dan tidak hanya berfungsi sebagai elemen estetis, tetapi juga sebagai media komunikasi teologis dan spiritual. Dalam perspektif ikon, warna memiliki kemiripan visual dengan makna yang diwakilinya, seperti putih yang melambangkan kemurnian dan kebangkitan. Dalam perspektif indeks, warna menunjukkan hubungan langsung dengan konteks liturgi tertentu, seperti ungu yang menandakan masa pertobatan. Sementara itu, dalam perspektif simbol, makna warna dibentuk melalui tradisi dan kesepakatan Gereja, seperti merah yang melambangkan pengorbanan dan Roh Kudus. Dengan demikian, warna pakaian liturgi para imam merupakan sistem tanda yang kompleks dan multidimensional yang mengandung nilai teologis, historis, dan spiritual. Penelitian ini menegaskan bahwa pendekatan semiotika Peirce efektif dalam mengungkap makna simbolik dalam praktik keagamaan, khususnya dalam liturgi Gereja Katolik.
Abstract:Passenger movement within aircraft aisles is an essential activity during the flight process, particularly inside narrow-body aircraft where mobility remains restricted. Interactions between passengers frequently trigger…
avoidance behaviors that potentially influence perceptions of safety, security, and comfort during travel. Therefore, this study aims to analyze passenger perceptions of aisle avoidance on Pelita Air flights based on these three specific dimensions. Methodologically, the research utilizes a quantitative descriptive approach involving a five-point Likert scale questionnaire. Data were gathered from 350 respondents who previously utilized Pelita Air flight services. Furthermore, the analysis was conducted by calculating mean values to determine the categorization of respondent perceptions. Findings indicate that all variables fall within the “good” category. Specifically, the mean value for safety reached 4.098, security 4.099, and comfort 4.077. Effectively, these findings demonstrate that the avoidance process in the cabin aisle is perceived as safe, orderly, and sufficiently comfortable despite the limited space for movement. Importantly, this study contributes to the understanding of passenger behavior in confined cabin spaces and becomes valuable input for airlines to enhance the quality of cabin services.
Abstract:Traffic accidents impose a heavy economic burden, particularly on victims’ medical expenses. PT. Jasa Raharja, a state-owned insurance company, plays a crucial role in providing compensation for hospitalization costs. This…
This study analyzes the impact of PT. Jasa Raharja’s insurance on inpatient expenses for traffic accident victims in Pekanbaru City. The research applies a quantitative approach with descriptive analysis and simple regression. Data came from 120 respondents, consisting of victims and their families who received insurance benefits. The findings show that PT. Jasa Raharja’s insurance claims cover an average of 67% of total hospitalization costs, significantly reducing the victims’ financial burden. However, the coverage ceiling remains limited and does not fully meet medical expenses. This study concludes that PT. Jasa Raharja makes a substantial contribution to financing accident-related hospitalization, although increasing the claim ceiling would better align with current hospital costs.
Abstract:Penelitian ini menyoroti krisis integritas kepemimpinan yang melanda Indonesia dan gereja, yang kerap dipengaruhi oleh adopsi model kepemimpinan sekuler yang pragmatis serta mengabaikan spiritualitas Alkitabiah. Walaupun…
keteladanan Yesus menjadi acuan utama, kajian teologis khusus tentang integritas spiritual kepemimpinan-Nya dalam Injil Matius masih terbatas. Tujuan penelitian ini adalah mendeskripsikan dan menganalisis integritas spiritual Yesus dalam Injil Matius serta menggali implikasinya bagi kepemimpinan Kristen di Indonesia, khususnya bagi guru Pendidikan Agama Kristen dan pemimpin gereja. Penelitian menggunakan metode kualitatif deskriptif dengan studi literatur serta eksegesis historis-gramatikal dan teologis terhadap Injil Matius. Hasil penelitian mendefinisikan integritas secara holistik sebagai kesatuan identitas diri, keaslian hidup, keberanian moral, kedekatan dengan Allah, dan kompetensi praktis. Integritas ini berakar pada relasi dengan Allah dan menuntut keselarasan antara perkataan, tindakan, serta kehendak-Nya. Kepemimpinan Kristen dipahami bukan sekadar kapasitas manusiawi atau posisi, melainkan panggilan ilahi yang menuntut visi rohani, integritas, dan pelayanan kasih. Empat kualifikasi integritas kepemimpinan Yesus yang ditemukan adalah: (1) Kepemimpinan melalui kehidupan doa yang tekun sebagai dasar ketergantungan total pada Allah dan ketaatan kepada kehendak-Nya; (2) Kepemimpinan sesuai tuntunan Roh Kudus sebagai sumber wibawa dan kuasa yang bersumber dari pengurapan ilahi; (3) kepemimpinan berdasarkan kebenaran firman Tuhan sebagai otoritas tertinggi, sumber kebenaran, inspirasi, hikmat, dan pendoman kehidpan; dan (4) kepemimpinan berkarakter ilahi yang nyata melalui kasih agape, kerendahan hati, belas kasihan, kejujuran, ketulusan, serta penolakan terhadap kemunafikan. Kesimpulannya, integritas kerohanian merupakan pilar fundamental yang menyatukan kedalaman spiritualitas dengan kredibilitas praktis, sekaligus memberikan kerangka teologis yang kokoh untuk membangun kepemimpinan Kristen yang otentik dan transformatif di tengah krisis integritas.
