Abstract

 Safeguarding and securing a secret data is something that must be done either in personal, organizational, corporate or governmental data but not a few do not know how to secure data, especially in a message, so this research is conducted to provide a way to encrypt messages.In this research using a collaboration of the Hill Cipher algorithm and Arnold cat map, used to get maximum encryption results on data or messages. In its application, the Hill cipher algorithm will be modified using a bios phoenix sound code and image. Hill Cipher and Arnold Cat Map algorithms are suitable to be combined because it will produce strong enough encryption because the results of text-based encryption from the Hill Cipher algorithm will be encrypted again using the image-based Arnold Cat Map algorithm.This research resulted in the modification of a Hill Cipher algorithm and Arnold Cat Map in the encryption process and description to improve the security of data and information. Keywords— Hill Cipher, Arnold Cat Map, Cryptography, Steganography

Abstract

Social media has impact for decision maker to get more insights broadly. Including for online travel agent company, where costumer’s interest to use online travel agent for their chosen agent will grows along with the high number of customer’s satisfaction. As a one of the most important point in distribution, company provides a platform that reliable and effective to purchase a trip and share information of their experience through Online travel agent. It is important to know how consumer considerate which one the online travel agent they choose. One of their method is looking at the reviews. Facebook is one of social media that provide numerous reviews through comments sections. The research purposes are twofold, algorithm comparison and reveal the effect of uppercase as well as punctuation mark. The accuracy comparison between Naïve Bayes and K-Nearest Neighbor is provided against the datasets. This research collects the data from user comments on Facebook about the biggest three online travel agents in Indonesia. We classify the comments into three categories which are positive, negative, and neutral. The result of this research is found that K-Nearest Neighbor have slightly higher accuracy than the Naïve Bayes. Moreover, lowercase text without punctuation achieves better accuracy for both of algorithm.

Abstract

For a company it is very vital. Customers are the key to running a business that is run. But in reality there are loyal customers and some are churned out. Churn is defined as the tendency of customers to stop doing business with a company. It is important for companies to be able to identify customers who have a tendency to be churn customers. Then a report is needed to be able to identify and make decisions for management. Prediction method using Naïve Bayes method produces an accuracy of 76% and K-Nearest Neighbor produces information with a K = 1 value of 73%, K = 3 which is 76% and K = 5 by 78% It can be concluded that the K-Nearest Neighbor Method with K = 3 has a better value. The results of customer predictions for a company can be used to take an example for the customer so they will not churn.  Keywords: Prediction, Customer, Churn, Naïve Bayes, Telecomunication, K-Nearest Neighbor.

Abstract

 Indonesia is a country famous for its spices wealth, spices have many benefits such as cooking and can also be used as medicine, but nowadays there are many Indonesian people who cannot distinguish each type of spices especially the rhizomes that will be used due to their shape quite similar, even though the selection of the right type of spices in accordance with the needs is very important because the spices used for cooking or medicine have different taste and efficacy, therefore the use of computer technology needs to be used to facilitate and accelerate humans in conducting classifications, this research classifies spices based on RGB and Texture colors using K-Nearest Neighbor Algorithm and distance measurement using Euclidean Distance, from 30 times the test experiment gets the result that the level of truth with K = 1 is 76%, K = 3 is equal to 67% and K = 5 by 63%. From these results it is known that based on GE colors and computer textures can classify spices but with a fairly low accuracy so that further development is needed such as adding form features. Keywords: classification, spices, K-Nearest Neighbor.

Abstract

In the current era of advances in information technology, optimal UI/UX planning is crucial for producing a well-structured information system. A focus on user interface (UI) and user experience (UX) is important in ensuring the effectiveness and suitability of applications to user needs. Therefore, this research aims to analyze the Usability and accessibility aspects of UI/UX design designed with the Neumorphism design style, especially to meet the organizational needs of the Computer Faculty Student Association (HIMAKOM) at Universal University. The user-centered design (UCD) method is used in the application interface design process, with Usability testing using the System Usability Scale (SUS) as an evaluation tool. The research results show that although UI/UX design obtained an average SUS score of 67.4, which indicates a slight level of acceptability, it is still included in the marginal high category. These results indicate that the design requires adjustments to improve the overall user experience. However, in terms of accessibility, the design shows feasibility with an average percentage value of 76, indicating adequate attention to user diversity. In conclusion, although the UI/UX design requires several improvements to increase its Usability level, the design has sufficiently paid attention to the accessibility aspect, so it can be considered feasible and able to meet the needs of the HIMAKOM organization. It is recommended to carry out continuous iteration based on user feedback to improve optimal user experience. Thus, this research can provide important guidance for the development of applications that can best meet user needs and preferences

Abstract

Batam merupakan salah satu wilayah di Indonesia yang termasuk kota heterogen dan multietnik dimana sebagaian masyarakatnya adalah etnis Tionghoa. Etnis tersebut memiliki budaya dengan keunikan arsitektur bangunannya, terutama pada bagian atapnya. Karena keunikannya, konsep arsitekturnya menjadi salah satu daya tarik untuk diketahui dan bahkan menjadi objek wisata. Untuk mempelajari konsep arsitektur tersebut, diperlukan instruktur yang paham dengan budaya tersebut. Apa lagi jika ingin menyebar luaskan serta mempromosikannya, tentu memerlukan media sebagai alat bantu. Untuk memenuhi kebutuhan tersebut, maka diperlukan perangcangan aplikasi memanfaatkan teknologi Augmented Reality (AR) yang berfungsi sebagai media pembelajaran dan promosi. Konsep perancangan yang digunakan menerapkan pendekatan konsep Game Development Life Cycle (GDLC) yang dimodifikasi menjadi tiga bagian utama, yakni: persiapan, pengembangan dan pengujian. Hasil pembuatan aplikasi dan evaluasi yang dilakukan, diperoleh responden sebanyak 43 orang yang terdiri dari laki-laki sebanyak 18 atau 42% dan perempuan sebanyak 25 orang atau 58%. Penyebaran aplikasi mendapatkan respon baik di masyarakat dengan memperoleh persentasee sebesar 79,88% atau tergolong kuat. Hasil penelitian menunjukkan bawah aplikasi ini sangat diperlukan dan berfungsi sebagaimana yang diinginkan.
