Abstract

The popularity of cybercrime caused unsafe information. Infrastructure IT made an effort to take in hand the problem, i.e. manipulating information. Cryptography existed as knowledge to protect information. To improve the security level, cryptography needs to be developed. Block Cipher Cryptography based on Dance Denok Deblong is designed to create a new cryptography. This cryptography is designed by using 4 process and 20 rounds. In fourth procesis transformed with S-BOX to get a more random ciphertext. Testing is also done using Avalanche Effect and Correlation value where the character change reaches 49,844%, so it can be used as an alternative in securing data

Abstract

Dogs are the most populated animals in 2016 according to a survey of pet populations by the UK's association of animal food makers (PFMA). With so many types of dogs and different characteristics, not all humans can choose the type of dog that suits their situation and condition. These non-conformities cause dogs to be dumped on the streets or abandoned without proper care. Therefore the dog characteristics assessment system is made which aims to facilitate the user in choosing the type of dog that is suitable for the user's situation and condition. This system is made using the TOPSIS method (Technique for Order Preference by Similarity to Ideal Solution). This system is based on the data of dogs registered with the AKC (American Kennel Club). This system uses eight criteria, three criteria for the filter process and five criteria for the weighting process. Of the five weighting criteria, there are three cost attributes and two benefit attributes. In the TOPSIS method (Technique for Order Preference by Similarity to Ideal Solution) uses the principle that the chosen alternative must have the closest distance from the positive ideal solution and the longest (farthest) distance from the negative ideal solution. The results obtained from this assessment system are by theory-based testing 50 times with a 78% suitability match percentage. The conclusion obtained from this research is the TOPSIS (Technique for Order Preference by Similarity to Ideal Solution) method is quite efficient to be applied in a dog characteristic assessment system

Abstract

Kedai Kolega is a business engaged in the production of food and beverages. Colleges Store provides purchase and reservation service. The problem at Kedai Kolega is the reservation process by coming directly to the place so as to make the cost and time inefficient for customers who are away from the location. Customers also can not make reservations outside the operator hours due to limitations of colleagues in serving customers in real time 24 hours a day, Rapid Internet development is the driving factor of e-commerce. The Internet is a global network that connects computer networks around the world. Using the Internet in this case E-Commerce will facilitate Kedai Kolega when performing data management more quickly and accurately and make reservations online. E-Commerce system is tested using black box and alpha test method. The results showed that E-Commerce is able to provide convenience to the colleagues in improving the quality of service to customers

Abstract

Tropical infectious diseases are frequent, serious and concerning for the people in Indonesia. Tropical infectious diseases can be fatal and cause death. But if we diagnose them earlier and get proper treatment, the story can be changed. In this research will make a mobile application using Naive Bayes and Forward Chaining methods for early diagnosing tropical infectious diseases including typhoid fever, dengue fever, tuberculosis, malaria, and measles. The process of this application will start with input of the symptoms felt by users, after the data collected, system will calculate the data with Naive Bayes formula. This application using 147 data training from interviewed with the experts. Based on the tests by System Usability Scale method shows above average users rating 73.875 %, which means the results of the application are acceptable. And Confusion Matrix method shows performance of the application as high as 76.74 %.

Abstract

The internet provides around the world facilities to reach customers without market restrictions, including e-commerce. As a result, the number of customers who depend on the Internet for purchases has increased dramatically. Potential cybercrime attacks such as phishing are criminal activities that attempt to obtain illegally sensitive information. The sensitive information can be in the form of a username, password, and credit card details. Then it is necessary to analyze the non-volatile data obtained in real and sourced from a Facebook forum. Data acquisition techniques use forensic live network data processing using Network Protocol Analyzer tools, namely Wireshark. The results of the investigation and analysis are summarized in the form of the table. The success of the investigation can be found in the source of the attack in the form of IP Address, URL phishing, DNS protocol, IMAP, username, password, FTP, SMTP, and HTTP. The analysis provides recommendations on how to avoid web phishing attacks.

Abstract

Andalas University is the oldest university outside Java Island, and is the fourth oldest university in Indonesia. The University of Andalas also has assets and facilities such as buildings, land, equipment, campus buses and official vehicles managed by the administration acnd general 2 fields under the leadership of the Vice Rector 2, the assets and facilities available at the university andalas are also leased to people who want to rent or use existing facilities. Payment transactions and report recaps are still done manually this makes managers in recording transaction data becomes difficult. The status of pay by the lessee is difficult to track if the leader requests the report results. Therefore we need an information system to manage rental transaction and facilities at university andalas, that is information system that can recap asset, tenant and payment data. The research method used is System Development Life Cycle (SDLC) research, in SDLC development process consisting of system planning, system analysis, system design, and system implementation. With this information system is expected both parties' transactions can be easily and mutually beneficial and the storage can also supervise transactions that exist wherever they are

Abstract

Ada sejumlah aplikasi dalam pengenalan pola yang membutuhkan citra dengan ukuran tertentu. Ukuran citra menentukan hasil dari pengenalan pola suatu sistem. Suatu metode interpolasi digunakan untuk menyesuaikan ukuran suatu citra. Kualitas suatu citra terinterpolasi bergantung pada metode interpolasi yang digunakan. Image Quality Assessment (IQA) memainkan suatu peranan penting dalam berbagai aplikasi pengolahan citra seperti peningkatan kualitas citra, kompresi citra, restorasi citra, dan lain sebagainya. IQA sangat dibutuhkan karena suatu citra dapat mengandung beberapa tipe derau seperti derau blur, perubahan kontras dan sebagainya. Pada penelitian ini dibandingkan 4 buah metode interpolasi yang digunakan untuk meningkatkan kualitas citra. Keempat metode tersebut adalah Nearest Neighbor Interpolation (NNI), Bilinear Interpolation, Bicubic Interpolation dan Nearest Neighbor Value Interpolation (NNVI). Metode-metode ini dianalisa dengan IQA. IQA yang digunakan adalah Image Quality Assesment Metrics (SSIM) dan A Feature Similarity Index (FSIM). Metode Bicubic Interpolation menunjukkan nilai yang paling baik untuk PSNR, SSIM dan FSIM. Metode NNVI menunjukkan nilai yang kurang baik dibanding ketiga metode interpolasi lainnya. Metode Bilinear Interpolation dan NNI memberikan kualitas yang berada ditengah-tengah antara metode Bicubic Interpolation dan NNVI.
