Pengembangan Media Pembelajaran Technical English Berbasis Digital

This research is conducted based on the problem in teaching learning process of technical English for civil engineering in STT Harapan Medan. The use of lecturer method, copied and printed teaching material make the students unmotivated to learn English. The solution for this problem, it is needed to develop learning media based on CAI  (Computer Aided Instruction). The objective of this research is developing digital English media designed for civil engineering students. This research conducted qualitative method using Development Research methodology, it is used Four D Model.  Case of this research in STT Harapan Medan. The result of this research is the application of digital teaching materials in learning technical English, especially in grammar in civil engineering class. The digital teaching materials for grammar was designed by using SOM application and the exercise was designed by using cartoon story maker. Keywords:  Computer Aided Instruction, Multimedi

Kombinasi RSA-CRT dengan Random LSB untuk Keamanan Data di Kanwil Kementerian Agama Prov. Sumatera Utara

In this study the authors use Cryptographic Algorithms Rivest Shamir Adleman Chinese Remainder Theorem (RSA-CRT) and steganography technique Random Least Significant Bits (LSB). RSA-CRT is basically the same as usual, but utilizing RSA CRT theorem to shorten the bit size decryption exponent d by hiding d on congruent systems that accelerate time decryption, the difference in the key generation process and the decryption process. Cryptographic algorithm RSA-CRT produce ciphertext stored into a picture (image) using Steganography technique Random Least Significant Bits (LSB). The workings of Random LSB is storing the message (ciphertext) in the first bit or the second bit random key for use random number generator Pseudo Random Number Generator (PRNG) with Linear Congruential Generator (LCG) method. Ciphertext stored in a picture  (image) has extracted key re-use random number generator at the time of inserting the message. Then the ciphertext is decrypted back by the algorithm RSA-CRT to produce the original text (plaintext). Merging Cryptographic Algorithm RSA-CRT with Steganography Technique Simple  LSB than with Random LSB generate higher PSNR and MSE is lower, which means better level of data security and more resistant to attack. Has more difficult to find a secret message by cryptanalysis and steganalyst

Aplikasi Pemilihan Bibit Budidaya Ikan Air Tawar dengan Metode MOORA – Entropy

At the beginning of the start of the business of breeding fish selection of freshwater fish cultivation becomes a difficult thing to do. The results of interviews with the Center for Research and Development of Freshwater Aquaculture said that there are 8 factors that influence the selection of freshwater fish cultivation seeds, namely temperature, water pH, location, elevation, dissolved oxygen, pond area, the ideal length of enlargement, feeding easier, fish. This research uses Decision Support System with Multi Objective Optimization By Ratio Analysis (MOORA) method as ranking and Entropy as weighting. The incorporation of the MOORA and Entropy methods gives the recommendation result by combining the objective system's subjective and subjective weights. It used priority criteria with temperature value 0,222, water pH 0,194, Eatability 0,111, community interest toward fish 0,055, dissolved oxygen 0,138, land height 0,167, ideal length of fish enlargement 0,027, and pool area 0,083 produce catfish as the best alternative of fish breeder water with value -0.1009.Keywords: Information, fish, DSS,  MOORA, Entrop

Pemanfaatan Telegram Sebagai Notifikasi Serangan untuk Keperluan Forensik Jaringan

Cyber attacks are a serious threat to network security, especially in routers that result in termination of connections, missing configurations that affect all communications and transactions between networks become impeded by the loss of many parties. The first step to do is to design and build an attack detection system that is Intrusion Detection System (IDS). The use of snort is useful for recording Distributed Danial of Services (DDoS) attacks as well as traffic data stored on the router stored in the log and forwarded to the instant messaging telegram application as a notification to alert the administrator. A telegram can be used not only as a notification but can also be used as a network forensic stage to strengthen evidence of an attack as a process of data collection for the purposes of the trial. The results showed that by utilizing Instant Messaging Telegram by designing wake Application (App) notification using PHP programming language able to detect attacks by using existing rules on snort and can serve as the basis of evidence of an attack. Keywords: Telegram, Intrusion Detection System (IDS), Snort, Network Forensics, DDoS.

Web-Based Applications in Calculation of Family Heritage (Science of Faroidh)

Separating of inheritance according in sciences of faroidh each heir does not get the same part depending on their relationship to the inheritance recipient. This is because the needs of each heir are different, such as heirs of boys and girls differ the reason boys have a big responsibility and if already married  should have been obliged to offer for his family while the daughter if already have family responsible for the necessities of life. In addition, in sciences of faroidh also there is a hijab or a barrier where heir can get a share can also not get a part depending on whether the heirs prevented it causing its own complexity in the calculations. Nowadays it is very difficult to meet people who understand about this division of inheritance. Just little of people are experts distribute inheritance based on faroidh. So created a web-based application to aid in the calculation and distribution of inheritance properly and managed computerized that can ease people in solving this problem

Penerapan Cloud Computing Pada Sistem Reservasi Homestay Dieng Berbasis Web

Homestay is one of the places needed as lodging facilities in the tourist area. In recent years, lodging business is greatly increasing. Business lodging in Dieng is one of the promising venture business' due to the increasing number of the tourists who interested to visit the tourist  places in Dieng and they need the hotel services. However, there are some managers who are unable to promote their lodging through the internet. Therefore, this research will make a software as a service in a cloud computing, regarding the Homestay Reservation System service in order to make the managers able to promote their homestay to public through the internet and it will make customers able to make a reservation through the software. This software was made by following waterfall paradigm in software engineering, start from analysis, design, implementation and testing. Testing result showed that the application deserved to be used.Keywords: information, cloud computing, homestay, reservatio

Menerapkan Konsep Ekonomi Berbasis Teknologi Blockchain Menggunakan Non-Fungible Token pada Game NFTSmith

The increased number of players and transactions in online games causes third-party markets to carry out buying and selling transactions, the security factor from the open market that determines the number of frauds ranging from between players to service providers. The methodology consists of four stages: understanding the problem in order to find various approaches to solving it, collecting data for relevant theories, system design (which includes blockchain system design and blockchain infrastructure) that is then translated into design so that the implementation can be clearly seen in NFTSmith, and system development. A blockchain-based economy eliminates the need for third-party transactions, and on-chain transactions can be carried out in a decentralized mannerKeywords: Blockchain, Decentralized Marketplace, Game Economy, Non-Fungible Token, Market
