Abstract

Dalam proses pembuatan surat perintah tugas, dinas kominfo kota medan saat ini masih melakukan secara sederhana  dengan pencatata manual menggunakan bantuan microsoft office dan microsoft excel. Hal ini mengakibatkan sistem menjadi kurang efektik dan efesien baik segi materi maupun waktu,terjadi kerusakan atau kehilangan data perjalanan dinas karena proses dan tata cara penyimpanan data yang tidak baik serta waktu pembuatan laporan perjalanan dinas yang cukup lama. Maka diperlukan suatu sistem komputerisasi yang sangat sesuai untuk mendukung kinerja dalam pengelolaan SPT, Sehingga dapat mengatasi permasalahan atau kendala pada sistem berjalan saat ini dengan memanfaatkan teknologi cloud computing serta menggunakan php native sebagai pemrograman dengan cara  pengamatan langsung, dan wawancara kepada pihak yang terkait menjadi analisa sistem yang digunakan untuk membangun sistem baru dalam penelitian ini. Dengan memanfaatkan sistem komputersisasi yang diusulkan ini secara baik kemungkinan adanya kesalahan dapat diminimalisasi serta pengolahan SPT menjadi lebih mudah.

Abstract

Tourist and culinary places are a trip or visit to a place with the aim of trying or tasting local specialties to enjoy the food and drinks that exist in the area. There are many tourist and culinary places in Indonesia that can be visited by tourists, one of which is culinary tourism in the city of Siantar. Enjoying culinary is the main goal for tourists in choosing tourist and culinary places. Convenience is a factor that influences tourists when they want to visit tourist and culinary places and sometimes tourists find it difficult to determine which tourist and culinary places to visit with the variety of tourist and culinary attractions available. For this reason, information about tourist and culinary attractions in the city of Siantar is needed by tourists who are visiting the city. This application is designed based on a website and uses a collaborative filtering algorithm method that will provide recommendations in the form of address information, ratings that have been given by previous users, and provide recommendations based on visiting patterns by users who have visited these tourist and culinary places. Keywords: Culinary, Tourist attraction, Siantar City, Website, Collaborative Filtering

Abstract

Disturbance in the image, especially digital images can be caused by noise, resulting in a decrease in the quality of the image. Image restoration is a technique used to recover the original image from a degraded image. Restoration is intended so that the information contained in a digital image becomes better/clear. The restoration process is carried out because the image quality is blurred or because of the noise contained in the image. Noise is the main problem encountered in digital image processing. The digital image restoration process always involves a filtering algorithm that is able to suppress the noise contained in the image. The active contour method is one approach to segmentation, where this method uses a closed curve that can move wide or narrow. The active contour process is a process that takes some of the signals of a certain frequency and discards signals at other frequencies. An initialization curve is placed outside of the object to be segmented, then through the iteration process the curve will move closer to the boundary of the object until finally finding the object boundary. This study aims to design a special system for character restoration in digital images using the active contour method. The implementation results show that the active contour method can be used to restore the image properly, this can be from the restored image, the condition of the image that has been given noise can approach the initial data. Keywords: active contour, digital image, character, restoration

Abstract

Papan tulis merupakan sarana paling penting dalam proses belajar mengajar. Saat ini, hampir seluruh dunia pendidikan di Indonesia masih menggunakan penghapus papan tulis biasa, yaitu dengan tenaga manusia. Kegiatan tersebut merupakan kegiatan yang tidak disukai dan membosankan karena dilakukan berulang – ulang dan dapat mengotori tangan. Debu atau aroma spidol yang keluar dapat mengganggu pernafasan. Oleh karena itu, dibuat suatu alat berupa penghapus papan tulis otomatis berbasis android dengan memanfaatkan 2 Motor DC sebagai komponen utama yang telah diintegerasikan dengan mikrokontroler yang digunakan sebagai penggerak penghapus yang akan menghapus bekas tinta pada permukaan papan tulis (whiteboard) dimana siapa saja bisa menghapus papan tulis dengan mudah pada bagian yang sulit dijangkau. Pada penelitian ini dapat memberikan kemudahan dalam menghapus bagian yang sulit dijangkau dan mengurangi kegiatan yang membosankan pada pengguna untuk membersihkan papan tulis (whiteboard) secara bersih hanya dengan menekan tombol SEMUA, KIRI, KANAN sesuai dengan hasil pengujian yang telah dilakukan. Dari hasil pengujian penghapus dapat disimpulkan bahwa alat dapat bekerja sesuai dengan yang diharapkan

Abstract

Cryptography can be used to process messages with certain algorithms so that the meaning of the message is difficult to understand. After that, steganography was used to hide messages in other forms. This study uses AES and Least Significant Bit (LSB) to build desktop-based applications using VB to send messages and get original messages. This application itself will concentrate the application of dual security for data and use WMA audio files to strengthen security on text data owned by users. Conceptually, security will be carried out by first encrypting messages using AES cryptography and then continuing the second security process by inserting text data in the WMA Audio file using the LSB algorithm to prevent indication or suspicion of the existence of important data or information that is inserted in the data.Keywords : Cryptography, Steganography, AES, LSB

Abstract

Operating systems for mobile devices are growing. Android is a mobile operating system that is now very popular and widely used by people. For the purposes of the security aspect, Android has also provided specifically for cryptographic functions, such as encryption, decryption, and so on. Insecure message delivery can occur because when sending, the message sent is in the form of an original message so that if a message is taken from the delivery line, the message will be known by unauthorized parties. So we need a security on a message data. Encryption and decryption can be used to make messages so that they cannot be read or understood by other people who do not have access rights. The technique of securing data and information is known as cryptography. The use of the Triple Transposition Vigenere Cipher (TTVC) algorithm has been carried out on SMS security (Short Message Service) in order to maintain the integrity and security of the message content and cover gaps in SMS security. The message sent will be encrypted using the Triple Transposition Vigenere Cipher first so that the contents of the message can be read by the sender and recipient. Based on what has been discussed above the author will design a Text Message Security Application Using a Combination Algorithm of Triple Transposition Vigenere Cipher and One Time Pad Based on Android Studio to provide security for messages from unauthorized parties.

Abstract

Learning media is anything that is used to convey messages or information in the teaching and learning process so that it can stimulate students' attention and interest in learning. Increasing the development of information and communication technology can have a positive impact on the education sector. Augmented Reality is part of the learning media that can be used to attract students' interest in learning. Augmented Reality has the advantage of being able to help improve student learning activities, simplify complex learning material, and present learning material practically. Insect animals (insecta) come from the Latin word insectum, which means cut into several parts, one of the classes of invertebrates in the phylum arthropods which have chitinous exoskeletons. The results of Augmented Reality learning media are that students are increasingly motivated to actively participate in learning activities, teachers can easily provide learning to motivate student
