Abstract

Pengaturan waktu, ruang, kelas dan matakuliah merupakan kegiatan dari penjadwalan matakuliah. sistem informasi penjadwalan kuliah di fakultas teknik dan ilmu komputer universitas buana perjuangan karawang yang dilakukan masih secara manual. penjadwalan perkuliahan dimana sejumlah matakuliah harus dijadwalkan kedalam ruang dan slot-waktu tertentu. untuk mempermudah proses pembuatan penjadwalan perkuliahan maka di buat secara komputerisasi. dalam pengembangan aplikasi dengan model prototype. Aplikasi ini di bangun mengunakan algoritma particle swarm optimization (PSO). Paricle Swarm Optomization (PSO) adalah teknik komputasi berbasis populasi yang dikembangkan oleh James Kennedy dan Russ Ebrhart pada tahun 1995. data yang digunakan dalam penelitian ini adalah data perkuliahan di fakultas teknik dan ilmu computer pada prodi teknik infomatika dan sisem informasi. pengujian dilakukan untuk mendapatkan hasil optimal dari algoritma PSO. pengujian menggunakan metode black box dan white box testing. Berdasarkan hasil pengujian dengan menggunakan algoritma particle swarm Optimization dengan jumlah partikel yang dibangkitkan mempengaruhi optimasi jadwal yang dihasilkan, semakin banyak partikel yang terlibat maka dapat menghasilkan jadwal dengan rata-rata hasilnya belum optimal.Kata Kunci— Paricle Swarm Optomization (PSO), Penjadwalan perkuliahan, Prototype.

Abstract

Security and confidentiality have become very important and continue to grow. In recent years, there have been several cases involving data security, such as the leaking of Facebook user account information. This is certainly a significant issue in the world of information technology and even the world of entrepreneurship because it involves one of the young entrepreneurs, Mark Zuckerberg. Main problem in this case is data security. who can know information and who should not know information. To overcome such things, research is made in the field of data and information security by analyzing one of the encryption and decryption techniques, namely RC4 cryptography. This study explains how RC4 cryptography works, the advantages and disadvantages of RC4 cryptography, and the effectiveness of RC4 cryptography. RC4 (River Ciper 4) is a decryption encryption technique that uses a key as a reference. The process consists of KSA, PRGA, and XOR. To find out the usefulness of RC4 cryptography, in this study, encryption and decryption were carried out on text data. There are several advantages and disadvantages to RC4 cryptography from a technical point of view. The advantage that needs to be underlined is that this RC4 cryptography uses a certain key as a reference, things like this can provide convenience to the encryption maker but can also be a threat. as a result RC4 can hide information very well while the secret key is not known by others. In addition to being used in text data, this cryptography may be used for other data such as audio and video.
