Abstract

MAN 02 Kepahiang is one of the schools in Kepahiang Regency which still uses a manual attendance process. In the process of teaching and learning activities students need a daily attendance process to process student attendance data which will be made as an attendance report which is one component of the assessment of the teaching and learning process. In implementing the manual attendance system carried out by students there are still deficiencies in terms of time efficiency in the process of recording attendance and preparing attendance reports for each class. In designing an attendance system using a QR Code in the form of a web base and using the PHP programming language with MySQL database processing also using the Waterfall method. This study aims to build an attendance system using the QR Code as a media for inputting student absentee data and in preparing student daily attendance reports it is made easier by having an attendance system built.

Abstract

Aplikasi presensi perkuliahan di Universitas Muhammadiyah Bengkulu perlu sekali dikembangkan sehingga lebih mudah dalam proses pelaksanaannya. Salah satu cara untuk mempermudah prosesnya menggunakan presensi Quic Response (QR) Code yang dapat dilakukan dalam kondisi perkuliahan daring ataupun luring. Metode QR Code yang digunakan adalah berupa penyimpanan Uniform Resource Locator (URL) terenkripsi dan ter-hashing yang dikombinasikan dengan filterisasi internet protocol address sehingga informasi yang tersimpan menjadi lebih aman dibandingkan bila dalam bentuk teks biasa. Metode pengumpulan data dengan menggunaka teknik observasi dan wawancara terhadap pengguna aplikasi terdahulu baru kemudian dilakukan analisa, perancangan dan pemrograman secara eksperimen pada modul-modul program yang berperan dalam proses presensi tersebut. Dari hasil penelitian ini QR Code terproteksi dan berhasil dilaksanakan serta dapat berintegrasi dengan beberapa learning management system (LMS), aplikasi media sosial yang sering digunakan oleh para dosen khususnya di Universitas Muhammadiyah Bengkulu. Hasil penelitian ini telah digunakan pada prose perkuliahan di Semester Ganji Tahun Akademik 2021 ini

Abstract

Universitas Muhammadiyah Bengkulu adalah perguruan tinggi swasta yang berada di Kota Bengkulu, Indonesia, yang berdiri pada tanggal 20 Juni 1991. Pada penelitian ini akan dibahas mengenai pengelolaan inventaris barang yang ada di laboratorium komputer Fakultas Teknik Universitas Muhammadiyah Bengkulu. Dalam pengelolaannya selama ini, terdapat beberapa masalah yang terjadi didalam proses pendataan barang dan laporan barang yang masih dilakukan dengan cara manual yakni dengan mencatat di buku kemudian dimasukan ke dalam microsoft excel. Cara tersebut dapat menyebabkan resiko kehilangan data, karena data hanya disimpan dalam buku serta file excel. Tujuan dari penelitian ini adalah membangun sebuah aplikasi inventrais yang diharapkan dapat meningkatkan kualitas pengelolaan data sehingga memudahkan kepala laboratorium dalam mengelola barang inventaris di laboratorium komputer. Sistem informasi dibangun dengan menggunakan bahasa pemrograman PHP dengan keamanan AES. Hasil penelitian ini yaitu Berhasil membuat aplikasi inventaris yang dapat mengimplementasikan keamanan AES, serta memiliki tampilan yang menarik.

Abstract

Learning activities are basically an effort to direct students into the learning process so that they can obtain learning objectives in accordance with what is expected. teaching and learning activities run properly, these activities are a process of teachers and students interacting with each other which will have a reciprocal relationship. influencing and influenced, the success of learning can be seen from many factors, namely the teacher and the students themselves. The problem is changing the habits of teachers who used to use the old method focusing on books and modules. They will have difficulty dealing with online teaching and learning activities. training is needed, it is possible to make interactive, digital-based learning media, which makes it possible to use the Covid-19 pandemic condition, which demands online or semi-annual teaching. offline. After attending the training, participants are expected to be able to take advantage of learning technology and take advantage of multimedia developments to create good learning media with Kinemaster, make attractive presentations using Canva with interesting features, VSDC Video Editor to create interactive learning need on going activities because most of the participants still need training to help the learning process lead to digital system, online-based and independent learning

Abstract

Scholarships are a form of assistance given to students or students in the form of funds or money that will be used to help the cost of the educational process and ease the burden on students in taking the study period, especially the cost issue, given a selective scholarship program.  This study aims to implement the Preference Selection Index (PSI) method in determining scholarship acceptance at SMA Negeri 2 South Bengkulu. This study uses a quantitative approach by using secondary data in the form of a decision matrix containing criteria for determining scholarship acceptance and data on students who have applied for scholarships in the previous year. The PSI method is used to determine the relative weight of each criterion and calculate the final score for each student. The results of this study show that the PSI method can produce objective and fair decisions in determining scholarship acceptance. In the application of the PSI method, the criterion with the highest weight is academic achievement and the criterion with the lowest weight is activeness in student organizations. The results of this study can be used as recommendations for the school in determining scholarship acceptance in the following years. It is hoped that the results of this study can help schools in selecting students who meet the criteria and deserve scholarship assistance to help with their education costs.

Abstract

Keamanan data merupakan kebutuhan krusial dalam komunikasi digital, terutama pada perangkat mobile yang rentan terhadap kebocoran dan pelanggaran privasi. Penelitian ini mengatasi gap dengan menguji integrasi komprehensif tiga metode pengamanan data dalam satu aplikasi Android: kriptografi AES-128 (untuk kerahasiaan), encoding Base64 (untuk kompatibilitas transmisi), dan hashing Bcrypt (untuk integritas). Metodologi penelitian menggunakan pendekatan rekayasa perangkat lunak berbasis Waterfall dan melibatkan pengujian performa algoritma secara simulatif pada pesan teks. Novelty penelitian ini terletak pada analisis kinerja terpadu ketiga algoritma pada platform mobile berdaya terbatas. Hasil penelitian menunjukkan bahwa integrasi ini bekerja secara 100% akurat dalam skenario enkripsi-dekripsi. Secara spesifik, AES-128 berhasil mempertahankan kecepatan pemrosesan rata-rata di bawah 50 milidetik per transaksi, dan Bcrypt terbukti menghasilkan hash yang unik dan tahan rainbow table. Disimpulkan bahwa aplikasi ini mampu melindungi pesan dari akses tidak sah serta menjadi solusi praktis dan efisien dalam meningkatkan privasi komunikasi digital. Penelitian ini memberikan kontribusi nyata berupa model implementasi end-to-end security yang terukur pada platform Android.
