Abstract

Saat ini banyak masyarakat Indonesia khusus nya daerah perkotaan yang ingin sekali Bertani namun tidak memiliki lahan yang cukup luas. Hal ini dikarenakan minim nya pengetahuan masyarakat dalam metode Bertani. Ada berbagai macam metode Bertani, diantaranya adalah dengan metode sistem akuaponik. Sarana multimedia berbasis animasi dapat digunakan sebagai salah satu media penyampaian informasi, Penelitian ini memanfaat kan animasi 3D sebagai inovasi dalam mengajarkan cara pembuatan Akuaponik. Animasi 3D ini di rancang menggunakan software blender. Proses perancangan dimulai dari  menentukan ide cerita, pembuatan storyboard, pemodelan objek, pemberian tekstur, menggerakkan animasi, rendering, sampai dengan proses penyuntingan. Hasil akhir dari animasi ini berupa video yang dilengkapi dengan musik latar, audio, dan teks penjelasan. Animasi 3D pembuatan sistem Akuaponik sebagai edukasi Bertani diharapkan dapat menjadi solusi dalam mengatasi keterbatasan lahan pertanian.Kata Kunci: Animasi 3D, Akuaponik, Blender.

Abstract

Message security is very important in maintaining the confidentiality of information, especially those containing important information whose contents should only be known by the entitled party. Therefore, security is needed for messages that are confidential so that messages cannot be intercepted by people who do not want them and the information content of the message becomes more secure. One way is to apply ElGamal and LSB cryptography methods to be able to provide security to text messages by inserting into digital images, the ElGamal algorithm focuses on the strength of the key in solving discrete logarithm problems. By utilizing large prime numbers and discrete logarithm problems which are quite difficult and also by applying the LSB method for text insertion, the security of the key is more guaranteed. The test results on five image objects with the .BMP extension on the application that was built were running well and correctly. The image that is inserted in the encryption process is the insertion of text in the image after it is decrypted and the image produced after the encryption and decryption process is no different from the original image and the same thing for the image size does not change

Abstract

The document files are electronic data that are often used to store information that is personal or confidential, therefore it is necessary to take action to keep the information accessible only to the owner of the data. In addition to the security aspect, the thing that needs to be considered is also about storage memory. Therefore, additional steps are needed to streamline the storage media and speed up the transmission process by compressing it first so that its size becomes smaller. In this study, will combine cryptography and compression techniques using the RSA algorithm for the purpose of securing data, then compressed using the Even Rodeh Code algorithm to reduce the size of the data. This research produces an application that can be used as an alternative solution in maintaining the confidentiality of document file data so that it can only be accessed by the data owner and can save the need for data storage space to be more efficient. The test results show that different test file sizes produce different Compression Ratio (CR), Space Savings (SS) and RT (Running Time) calculation values as well. The larger the size to be compressed, the larger the size that can be reduced or the greater the storage space that can be saved. While the RT results have increased in value constantly along with changes in the size of the test file used. This means that the larger the size of the test file to be compressed, the longer it will take to compress it

Abstract

Keamanan data pada dokumen digital merupakan aspek penting, terutama pada dokumen PDF yang sering digunakan dalam berbagai transaksi bisnis dan pertukaran informasi sensitif. Penelitian ini bertujuan untuk merancang dan mengembangkan aplikasi pengamanan data pada dokumen PDF dengan menggunakan kombinasi algoritma Diffie-Hellman dan RSA. Diffie-Hellman digunakan untuk pertukaran kunci secara aman antara pengirim dan penerima, sedangkan algoritma RSA berperan dalam proses enkripsi dan dekripsi data. Penggunaan kombinasi kedua algoritma ini diharapkan mampu meningkatkan keamanan dengan meminimalisir risiko serangan pihak ketiga selama proses transmisi data. Pengujian dilakukan untuk memastikan tingkat keamanan, kecepatan enkripsi, serta efisiensi penggunaan sumber daya pada aplikasi. Hasil pengujian menunjukkan bahwa aplikasi ini mampu melindungi data dengan baik dan tetap efisien dalam penggunaannya. Dengan demikian, aplikasi ini dapat diimplementasikan sebagai solusi pengamanan data pada dokumen PDF untuk berbagai kebutuhan.

Abstract

Cats are popular pets, but choosing the right food for them can be a challenge. Conventional cat food product sales catalogs may no longer be attractive enough for modern consumers who are used to advanced technology. Therefore, this study proposes the implementation of Augmented Reality (AR) in an Android-based cat food product sales catalog application. By using AR, consumers can see cat food products in real life and listen to product descriptions in voice form. The results of this study stated that 21 respondents strongly agreed with this application, with an approval rate of about 80%. This shows that the application is very useful in helping cat owners choose the appropriate food.

Abstract

This research discusses the evaluation and implementation of the YOLOv4 model in detecting and tracking vehicle types in the context of road traffic. To address the research questions, the study examined the model's performance across various aspects. The results indicate that the YOLOv4 model achieved a Mean Average Precision (mAP) of 77.88% on the training dataset after 7000 iterations. The model exhibits a commendable ability to detect different vehicle types within images, with varying accuracy rates across distinct classes. The developed application within this study can record detection data for every frame within a video sequence, providing crucial information for analyzing vehicle density on roads. Despite its relatively high accuracy level, errors persist in object detection and labeling. In conclusion, this research offers insights into the capabilities and potential of the YOLOv4 model in addressing challenges related to vehicle detection in road traffic, while also identifying areas that warrant further improvement.

Abstract

Jaringan komputer tanpa segmentasi berpotensi menimbulkan permasalahan seperti tingginya trafik broadcast, rendahnya keamanan, dan sulitnya pengelolaan jaringan. Untuk mengatasi hal tersebut, penelitian ini menerapkan Virtual Local Area Network (VLAN) dan Inter-VLAN Routing pada topologi jaringan. VLAN digunakan untuk memisahkan jaringan berdasarkan divisi (Administrasi, Keuangan, IT Support, dan HRD) sehingga komunikasi dalam satu VLAN menjadi lebih efisien dan aman. Agar perangkat dari VLAN yang berbeda tetap dapat berkomunikasi, diterapkan konfigurasi Inter-VLAN Routing dengan metode router multi-interface. Implementasi dilakukan melalui perancangan topologi, konfigurasi switch untuk segmentasi VLAN, serta konfigurasi router sebagai penghubung antar VLAN. Hasil pengujian menunjukkan bahwa jaringan memiliki kualitas sangat baik berdasarkan parameter QoS: delay rendah (0–6 ms), packet loss 0%, dan jitter kecil. Dengan demikian, penerapan VLAN dan Inter-VLAN Routing terbukti meningkatkan efisiensi, keamanan, serta fleksibilitas jaringan, sehingga dapat menjadi solusi tepat bagi organisasi skala menengah hingga besar. Kata kunci: VLAN, Inter-VLAN Routing, Router, Segmentasi Jaringan
