Abstract

Latar Belakang : Pada zaman seperti sekarang dimana semua serba di permudah dengan hadir nya teknologi sehingga masyarakat dan perusahaan pun tidak akan lepas dari kejanggihan teknologi tersebut. PT Power Line Diesel Inti Pratama Tangerang Legok merupakan perusahaan swasta yang masih menggunakan sistem manual dalam pengolahan data, terutama pada pengolahan data persediaan stok barang sehingga memperlambat dalam proses pengolahan data dan pengontrolan persediaan barang. Tujuan : Untuk mengatasi masalah tersebut, penulis merancang aplikasi Pengelola Persediaan Barang Berbasis Java, dengan aplikasi NetBeans IDE 8.1. Metode : Metode Penelitian yang di gunakan yaitu dengan Waterfall karena metode ini lebih efisien karena dari perencanaan sampai testinnya secara urut dilakukan agar penulis juga tidak keluar dari  konteks. Hasil : setelah menggunakan sistem pengelola persediaan barang berbasis java ini dapat mempermudah dan mempercepat kinerja bagian gudang serta dapat mengontrol jumlah persediaan barang.

Abstract

Absensi karyawan di PT Gita Variasi yang masih menggunakan kartu print, masih manualnya rekapitulasi untuk pengolahan data karyawan dan sulitnya melakukan pencarian dokumen absensi karyawan adalah latar belakang penulis dalam membuat aplikasi informasi absensi karyawan. Aplikasi ini dirancang dengan menggunakan RFID. RFID ini dihubungkan dengan komputer dan database. Dalam penggunaannya, karyawan cukup mendekatkan id card ke RFID saat melakukan absensi ketika datang dan pulang. Aplikasi ini juga dapat  mengelola dan  mencetak laporan absensi karyawansetiap harinya . Dari hasil laporan absensi karyawan yang tepat dan real time, aplikasi ini sangat membantu memberikan solusi dari masalah–masalah absensi karyawan yang sebelumnya manual dan laporan karyawan di PT Gita Variasi.

Abstract

Pada umumnya di dalam kampus, perusahaan atau organisasi, suatu dokumen digital disimpan di dalam komputer begitu saja tanpa adanya pengamanan sama sekali, sehingga dapat memungkinkan pencurian data oleh pihak yang tidak berwenang. Penelitian ini bertujuan untuk mengamankan dokumen dari pencurian pihak yang tidak berwenang dengan pembuatan suatu aplikasi enkripsi atau perubahan plaint text menjadi cipher text dengan kriptografi algoritma Blowfish. Namun sebelum melakukan enkripsi, dokumen dikompresi dahulu dengan metode Huffman agar ukuran dokumen lebih kecil sehingga proses enkripsi lebih optimal. Hasil penelitian ini dapat menghasilkan suatu aplikasi yang dapat memperkecil ukuran dokumen dan mengubah dokumen asli menjadi dokumen acak (sulit dipahami isinya) dalam menjamin keamanan data.

Abstract

Current technological developments make information needs very important. However, information that becomes confidential will become public information due to insecurity of the information in the process of exchanging information from the sender to the recipient of the information. In this regard, there are several things that must be considered during the process of sending messages, namely confidentiality, integrity, availability, authenticity, and non-repudiation. On this basis, the authors combine information security with cryptographic and steganographic methods. Cryptography is the change of the original message into a secret message, while steganography is the art of inserting messages into a media so that other people do not realize that there is a secret message in the media. The cryptographic methods that I use are the Blowfish method and the LSB steganography method. The insertion method using the LSB method is the process of inserting messages by presenting binary image files or images with binary representations of secret messages to be hidden. Thus, at every pixel a 24-bit BMP image or image file can be inserted with 3 message bits. The result is a secret message successfully inserted into the picture and reduce the suspicion of others that the picture has confidential information.

Abstract

Technological developments have positive and negative impacts for users. Information is easily and quickly accessed by anyone, anytime and anywhere. To maintain security, an effort is needed to secure information from unauthorized parties. Cryptography and steganography as a way to maintain the security of this information. The information we have (plain text) will be converted into random or hard-to-understand information (cipher text), commonly known as encryption. Furthermore, the random information will be hidden or inserted into the digital image (encoded) so that it will not make other people suspect that the digital image contains information that is being hidden. In a digital image that has been inserted with confidential information (stego image), there is no difference of visual man either before or after inserting the confidential information. This research succeeded in securing information in the form of documents in pdf, xlsx, docx, pptx and txt formats using Blowfish cryptography and LSB Steganography. The size of the document resulting from the encryption process becomes smaller with the Huffman compression process with an average value of 57% of the original document. The test uses 3 different files and 3 images in each file format, namely pdf, xlsx, docx, pptx and txt. Tests on stego images produce high quality with an MSE value of 0.092 and a PSNR of 57.12 dB.

Abstract

This research aims to develop a web-based e-warehouse system for PT. XYZ, a national private company engaged in the printing and packaging industry. Currently, the company still employs conventional methods for data processing, leading to file accumulation and difficulties in accessing archived data. Drawing from previous studies on similar issues in other companies, the author will construct a web-based system using the Laravel framework and Agile methodology to expedite software development. The system aims to facilitate the management and control of raw material inventory, as well as streamline processes related to incoming and outgoing goods and inventory requests. The research employs a quantitative method with observation, interviews, and literature review as approaches. The results demonstrate that the web-based system enhances efficiency in accessing and processing warehouse data in real-time, minimizing stock calculation errors, and presenting warehouse information effectively through an intuitive and informative interface.
