Abstract

Perkembangan data yang pesat akan membutuhkan keamanan dalam pengiriman data sehingga pihak lain yang tidak diinginkan tidak dapat melihat isi data tersebut. Salah satu cara untuk mengamankan data adalah dengan menggunakan kriptografi. Penelitian ini mengembangkan sebuah aplikasi yang dapat melakukan kombinasi kriptografi yang lebih aman karena pesan yang dikirim harus melalui dua kali proses enkripsi dan dekripsi. Algoritma yang digunakan dalam penelitian ini merupakan gabungan dari algoritma RSA dan algoritma AES. Algoritma RSA digunakan oleh pengirim untuk menghasilkan kunci publik dan pribadi. Algoritma RSA juga digunakan untuk mengenkripsi kunci rahasia, dan algoritma AES digunakan untuk mengenkripsi plaintext. Pengirim akan mendapatkan kunci pribadi, kunci rahasia terenkripsi, dan ciphertext. Penerima mendekripsi kunci rahasia terlebih dahulu menggunakan algoritma RSA, kemudian mendekripsi ciphertext menggunakan algoritma AES dan kunci rahasia.

Abstract

Bank Sampah Hanum yang berlokasi di Perumahan Vila Mutiara Gading 3, Bekasi, mengalami kendala dalam pencatatan transaksi yang masih menggunakan manual. Hal ini menyebabkan ketidakakuratan data dan keterbatasan akses informasi bagi warga. Penelitian ini bertujuan untuk merancang dan membangun aplikasi bank sampah berbasis Android guna mempermudah pencatatan transaksi, pengelolaan data nasabah, serta pengecekan saldo tabungan secara real-time. Metode Rapid Application Development (RAD) digunakan dalam pengembangan aplikasi ini, dengan database MySQL sebagai media penyimpanan data. Hasil implementasi menunjukkan bahwa aplikasi ini mampu meningkatkan efisiensi pencatatan transaksi bank sampah, mengurangi risiko kehilangan data, serta mempermudah warga dalam mengakses informasi saldo tabungan dan histori transaksi mereka.

Abstract

This study aims to develop a web-based learning model on the fuel system material and determine the feasibility of the learning model product based on the assessment of 2 material experts, 2 media experts and 30 students at SMK Negeri 54 Jakarta. This research method is Research and Development (R&D) with the ADDIE development model consisting of five stages, namely Analysis, Design, Development, Implementation, and Evaluation. The results in this study are a web-based learning model that can be accessed via computers and smartphones with the address https://teknikengine.000webhostapp.com. In this study, it was shown that the level of feasibility of the learning model based on the assessment of material experts from all aspects obtained a percentage of 88.33% which was included in the "Very Eligible" category. Media experts in all aspects obtained a percentage of 85.38% which was included in the "Very Eligible" category and the satisfaction results by students in all aspects obtained a percentage of 89.23% which was included in the "Very Satisfied" category. Thus, the web-based learning model on this fuel system material is "Very Appropriate" to be used as a learning model Keywords: Learning Model Development, Feasibility
