Abstract

KUA (Religious Affairs Office) is a public institution that represents Islamic religious affairs to officially marry a couple (man and woman) in the eyes of the law in Indonesia. KUA is a public institution organized by the government which carries out some of the tasks of the Regency and City Ministry of Religion, especially in the field of Islamic religious affairs, Tanjung Tiram District, Batu Bara Regency. The duties of the Tanjung Tiram District KUA include marriage registration and reconciliation services in the Tanjung Tiram District location. Apart from providing good service to the community, it is also necessary to record marriage data and references that are integrated on an application basis. Based on data in the field, the process of recording marriages and reconciliations still uses paper media as data archives, so it takes a long time to search for data in making reports. The system for processing marriage registration data and making reports also makes it easier for people who want to register for marriage registration. The software system development uses Visual Basic as the programming language and Microsoft Access as the database. This application system can provide information regarding the marriage contract schedule and make it easier for the KUA head to report on the implementation of the marriage contract to make institutional policies.

Abstract

This study aims to classify the ripeness level of mango fruit using a Convolutional Neural Network (CNN) model based on digital images. This classification is important to help the automatic sorting process in the agricultural industry that relies on accuracy in determining fruit quality. Based on the literature review, CNN has been widely used in image-based object recognition because of its ability to extract visual features automatically. Previous studies have shown that CNN is effective in image classification, but the results are highly dependent on the quality of the data and the model parameters used. This research method involves collecting mango fruit images at three levels of ripeness (raw, half-ripe, ripe), which are then processed and analyzed using the Orange application with CNN architecture. Model evaluation was carried out using accuracy metrics, AUC, confusion matrix, and visualization through box plots and scatter plots to see the distribution and differences in data between classes. The results showed that the CNN model obtained an accuracy of 53.3% and an AUC value of 0.717, which indicates the model's initial ability to distinguish ripeness categories but with a fairly high level of misclassification. There is still overlapping data between classes, especially between the raw and half-ripe classes, which indicates the need for additional features and parameter refinement. In conclusion, CNN has the potential to be used in classifying the ripeness level of mango fruit, but its performance can be improved through feature development and deeper model tuning.

Abstract

Keamanan data dan autentikasi pengguna merupakan aspek penting dalam pengembangan aplikasi digital, terutama aplikasi yang berkaitan dengan transaksi online. AY Pulsa sebagai aplikasi penyedia layanan pembelian produk digital berupaya meningkatkan perlindungan akun pengguna melalui penerapan fitur One-Time Password (OTP) sebagai lapisan keamanan tambahan. Penelitian ini bertujuan untuk menganalisis peran, manfaat, serta dampak penggunaan OTP dalam meningkatkan keamanan login pada aplikasi AY Pulsa. Metode penelitian yang digunakan adalah deskriptif kualitatif dengan sumber data primer melalui wawancara langsung bersama pemilik aplikasi. Hasil wawancara menunjukkan bahwa sebelum penerapan OTP, sistem autentikasi hanya menggunakan username, email, dan password, yang secara umum sudah fungsional namun tetap memiliki potensi risiko penyalahgunaan, seperti password ditebak, dibocorkan, atau digunakan di banyak platform oleh pengguna. Meskipun pemilik aplikasi menyatakan bahwa belum pernah terjadi kasus pembajakan akun, kekhawatiran terkait keamanan tetap menjadi pertimbangan penting. Penerapan OTP dipilih karena sifatnya yang mudah diimplementasikan, tidak memerlukan biaya tambahan, serta memiliki tingkat keamanan yang tinggi. Dalam proses login, sistem mengirimkan kode OTP melalui WhatsApp atau email yang hanya berlaku selama 20 menit. Hal ini memastikan bahwa setiap upaya login benar-benar dilakukan oleh pemilik akun. Hasil penelitian menunjukkan bahwa setelah OTP diterapkan, pengguna memberikan respon positif dan merasa lebih aman ketika mengakses aplikasi. Rating aplikasi juga mengalami peningkatan. Secara keseluruhan, OTP terbukti mampu meningkatkan standar keamanan AY Pulsa sekalipun tidak ada riwayat kasus penyalahgunaan sebelumnya. Penerapan fitur ini juga memberikan kepercayaan lebih kepada pengguna bahwa akun mereka terlindungi dengan baik.

Abstract

Keamanan data merupakan komponen utama dari layanan komunikasi berbasis cloud, karena data bisa bahkan sering kali hilang dan disimpan di beberapa server. Enkripsi End-to-End (E2EE) muncul sebagai mekanisme perlindungan yang memungkinkan hanya penerima dan pengirim yang bisa dapat mengakses konten komunikasi dari server cloud, sedangkan pengguna ketiga tidak bisa mengakses data cloud tersebut. Artikel ini mengevaluasi efektivitas E2EE dalam mengurangi risiko kerusakan data dalam layanan komunikasi berbasis cloud dengan tinjauan literatur, analisis teori keamanan, dan simulasi konseptual vektor ancaman seperti akses tidak otentik, penyadapan, dan kerusakan metadata. Hasil menunjukkan bahwa E2EE secara substansial menurunkan kemungkinan kebocoran data jika diimplementasikan dengan manajemen kunci dan endpoint security yang memadai. Namun, ada tantangan signifikan: metadata dan informasi kontekstual tetap berisiko bocor, serta performa sistem dapat terpengaruh. Temuan ini menekankan perlunya penerapan E2EE disertai kebijakan keamanan menyeluruh dan edukasi pengguna.
