Abstract

BSA Land merupakan pengembang properti yang berkomitmen dalam pengembangan perumahan, area bisnis dan pasar segar. BSA Land, dalam proses produksi perencanaan menghasilkan gambar-gambar yang bersifat penting, diantaranya Masterplan, Siteplan dan Artist Impression. Gambar-gambar tersebut tidak diperkenankan untuk disebarluaskan sebelum menjadi media publikasi seperti brosur, baliho dan banner, sehingga perlu diamankan. Dengan berperkembangan nya teknologi informasi, keamanan dalam penyimpanan dan pengiriman data sangat diperlukan demi menjaga kerahasiaan data tersebut. Salah satu cara mengamankan data rahasia tersebut adalah dengan menggunakan teknik steganografi. Pada tahap pembangunan aplikasi ini menggunakan bahasa pemrograman java. Data yang dapat di encode berupa gambar berformat (*.png). Berdasarkan hasil uji coba yang dilakukan pada aplikasi ini menggunakan metode Steganografi Least Significant Bit (LSB) rata-rata hasil encode pada penelitian ini adalah 5242880 Byte, rata-rata hasil decode adalah 1061795,84 Byte. Proses encode pada penelitian ini rata-rata membutuhkan waktu 120322.5 Milidetik, Sedangkan rata-rata proses decode file membutuhkan waktu 13506.75 Milidetik.

Abstract

Information technology has benefits to help and make it easier for humans to do everything in sharing communication. During the pandemic, PT. Royal Audrey Megah is one of the companies implementing Work From Home (WFH). To maintain a good quality of support in hosting services, the Customer Service and IT Support division can access helpdesk application through the internet connection. Applications that can be accessed from the internet bring many benefits to their users, even though not spared from their negative impacts. Given this, data is a very valuable asset and must be protected. Data security can be done, one of which is by securing from the database side. Database security can be done by implementing symmetric cryptography Advance Encryption Standard (AES) and Vigenere. The purpose of this study is to minimize the occurrence of database leaks and misuse by irresponsible parties. The cryptographic techniques used are the Advanced Encryption Standard (AES) and vigenere methods. From the results of the implementation, it was concluded that the application is able to secure data in an encrypted database so that it can minimize the occurrence of misuse or manipulation of data by people who do not have authority over the data.

Abstract

The trash bins in RT 01/08 currently have only one container, causing organic and non-organic waste to mix. This situation has led to environmental issues in RT 01/08, making the surroundings unpleasant and emitting a strong odour due to the accumulation of mixed waste. The negative impacts of this mixed waste, we can be reduced by separating the trash according to its respective categories when disposing of it. With the advancements in the era of globalization and information technology, especially in the field of microcontrollers and sensors, there have been significant improvements in human life. The emergence of various new technologies can aid human activities and also have a positive impact on environmental cleanliness. The purpose of this research is to develop an automated trash bin that can sort organic and non-organic waste based on mobile technology. By doing so, it can reduce the mixing of different types of waste in the environment, and users can control the opening and closing of the trash bin. The prototyping method tested has proven to work well as desired. This prototyping method involves designing a system and device that can automatically sort different types of waste, producing separate outputs for organic and non-organic waste. Ultrasonic sensors are used to detect the proximity of users, while capacitive and infrared proximity sensors are used to differentiate between organic and non-organic waste. The testing results of the automated trash bin showed that the ultrasonic sensor effectively detects the proximity of users, enabling the trash bin lid to open and close automatically. In distinguishing organic from non-organic waste, the capacitive proximity sensor can detect organic waste such as vegetable scraps, fruit peels, and leaves. Meanwhile, the infrared proximity sensor can detect non- organic waste such as plastic bottles and foot wrappers. However, both proximity sensors experienced a delay in detecting waste, taking approximately 1-3 seconds. Furthermore, the testing results also had a positive impact on the community, raising awareness among people about the importance of disposing of waste according to its respective categories.
