The security and confidentiality of data are one of the aspects that are very important in information systems at this time. Rapidly development of science and technology allows the emergence of new techniques, which can be misused by certain parties that threaten the security of information systems. The existence of these things needs to be applied to data security techniques to anticipate threats such as techniques of cryptography and steganography. This study combines two techniques securing data i.e. cryptography Hill Cipher (HC) method and steganography End of File (EoF) method. The results obtained from a combination of methods HC and EoF were successfully implemented in the process of encryption and decryption text messages which will then be inserted into the picture. The message was successfully inserted and extracted back on all sample images either by formatting *.jpg and *.png as well as at a resolution of 256x256 pixels and 512x512 pixels. Based on the results of the test image using MSE and PSNR resulting image quality is not good because the average value of the MSE obtained high 11263.113 and the value of average PSNR low 15.299 dB good image resolution 256 x 256 pixels and 512x512 pixels.Keywords—End of File, Hill Cipher, Cryptography, SteganographyDOI : 10.5281/zenodo.3255127

Cloud Computing technology can be a solution to overcome the problem of storing data on a computer that is often used by many people. One of them is the OwnCloud application service. OwnCloud is an open source software, which means that anyone can use it for free and change the contents of the service. With the concept of cloud storage, users who access OwnCloud must log in first to access data located in the cloud storage. By utilizing a WiFi network to access OwnCloud, all forms of data sharing and synchronization can be accessed on the features provided.Difficulties of staff, lecturers and students to share study program data become difficulties that hinder activities in the academic community. So the results of this study conclude that OwnCloud services can be an efficient solution in managing files if implemented on a centralized campus.Keywords—Cloud Computing, Cloud Storage, Storage, OwnCloudDOI : 10.5281/zenodo.3066822

Pada dunia kerja, banyak perusahaan yang memanfaatkan seorang psikolog (pakar psikologi) untuk menyeleksi calon karyawan karena penempatan karyawan yang tepat dapat membantu untuk meningkatkan produktivitas perusahaan. Penyeleksian calon karyawan melalui metode wawancara saja tidak akan cukup untuk menentukan calon karyawan tersebut layak atau tidak diterima, karena pada prakteknya terkadang kinerja yang diberikan tidak sesuai dengan hasil wawancara (interview). Di samping itu, biaya seorang psikolog yang cukup mahal membuat beberapa perusahaan kecil dan menengah lebih memilih tidak merekrut seorang psikolog sebagai divisi human resource. Oleh karena itu sebuah sistem pakar analisa kepribadian diharapkan dapat menjadi salah satu alternatif solusi agar proses penyeleksian lebih efisien dan optimal. Metode yang digunakan adalah Certainty Factor, pada metode tersebut dapat mengatasi ketidakpastian pengambilan keputusan dikarenakan dibutuhkan beberapa tes yang lebih kompleks dan lengkap untuk menentukkan kepribadian seseorang. Aplikasi ini akan memberikan hasil analisa tes berupa kecenderungan terbesar tipe kepribadian yang dimiliki calon karyawan sesuai jawaban yang diberikan beserta jumlah persentasenya. Berdasarkan penilaian pakar untuk ketepatan sistem dalam menganalisa kepribadian calon karyawan, terlihat bahwa aplikasi sistem pakar analisa tipe kepribadian ini memiliki tingkat rata-rata akurasi sebesar 90.84%.

Security of a website is a very important aspect. Because unsafe websites will easily be damaged the integrity of the data and information through various attack. SQL Injection is one type of attack that often occurs on websites. SQL Injection is a method for entering SQL commands as an input through a web to get database access. Insecure URLs and Login forms are often targeted by SQL Injection attacks to exploit web databases. There are many ways to prevent SQL Injection attacks and one of them uses cryptographic techniques to encrypt URLs and Login Forms of websites into an incomprehensible codes or passwords. The cryptographic method used is blowfish algorithm. This research aims to tests the performance of blowfish to prevent SQL Injection attacks through the implementation of URL and Login Form encryption. Web security from SQL Injection attacks is tested before and after encryption. Attack testing is done manually and automatically. Automatic testing using SQL Map and JSQL Injection applications. The test results prove that the implementation of URL and login form encryption uses blowfish algorithm is effective to prevent SQL Injection attacks because SQL Injection attacks always fail after implementation of URL and Login Form encryption.

A technological development has been affecting the advancement of storage media on computers from time to time. One of the advancement types is the cloud-based store media, in this case, Cloud refers to a metaphor of internet files and data stored on a computer where the users are required to create a Cloud Storage account. Cloud Storage is a storage media that requires access to an internet network. It means as long as the computers are connected to the internet, users no longer need to use a USB flash drive, hard drive or other storage hardware for data storage mobility. However, the security of files and data on Cloud Storage is still very vulnerable to be attacked or retrieved in the database, along with the development of increasingly sophisticated computer technology, the world of information technology requires a stronger and safer cryptographic algorithm. Most recently, the Advanced Encryption Standard (AES) is a secure cipher algorithm for protecting confidential data or information. The results of this study show that the Private Cloud Storage System is able to run well which can be seen from the results of testing this private cloud storage system, all existing menus can run and function properly and from the results of encryption and decryption tests that have been performed on eight types of files show that the testing of six types of files are successful, namely images, .doc, .pdf, .xsls, .ppt, and .txt, whereby those of six types of files are safe based on security testing. For .doc, .xsls, and .txt files when those are opened the files become scrambled. Furthermore, for images, .pdf, and .ppt files an error display will appear when those are opened. Meanwhile, the other two files which are the .mp3 and video type files failed because the algorithm is not able to encrypt and decrypt the file types Keywords— Cloud Computing, Private Cloud Storage, AES, Encryption, Decryption

The development of artificial intelligence has now undergone significant changes. This underlies the birth of a method to deal with object detection in real time with high accuracy. Basically Deep Learning is the implementation of the basic concept of Machine Learning which applies the smart algorithm with more layers between the input layer and the output layer. Convolutional Neural Network (CNN) is one method of Deep learning (DL) that can be used to detect and recognize an object in a digital image. The ability of CNN is claimed to be the best model to solve the problem of object detection and object recognition because it is a development of the backpropagation method and does not require large computation in the process. The results obtained in this study that android applications can run well with an accuracy of 92.33% can be seen from the test results using the 10-fold cross validation method, all available menus can be run and the mention of object labels is appropriate for image recognition and classification. Calculation of precision and recall has good values, each at 97.51% and 94.33%. In the classification process, objects that do not exist in datasets that have been modeled by the system will be null or unrecognized, especially in the image of an object captured by an Android camera that has many objects and is close together
