The repetitive and symmetrical patterns are formed by geometric transformation, which comprises translation, rotation, reflection, and glide reflection. In mathematics, the study of repetitive patterns on a plane, formed by geometric transformations, belongs to the plane symmetry group. This plane symmetry group is often referred to as plane crystallographic group or wallpaper group that comprises 17 known patterns. The purpose of this research is to generate various patterns from a basic pattern by applying the concept from the&nbsp;&nbsp; wallpaper group. Furthermore, this research also identifies four cloth motifs and categorizes them to the wallpaper group. This research was conducted by: (1) determining and creating a basic pattern that will be used to form other patterns, (2) generating 17 patterns from the basic pattern based on the patterns in the wallpaper group, (3) identifying some existing motifs downloaded from the Internet and categorize them to the wallpaper group. The basic pattern used in this research is a spiral pattern. The results obtained from this research are the 17 different spiral motifs as well as the identification of four motifs obtained from the Internet to one of the 17 patterns of wallpaper group.</em></p> 2021-07-17T18:57:31+07:00 ##submission.copyrightStatement## Versioning Catcher Software (VCS) untuk mendeteksi Sensitive Information File Versioning pada Linux Server 2021-07-19T00:04:53+07:00 Rhenaldo Delfi Nugraha Dian Widiyanto Chandra <p><strong><em>Abstract </em></strong><em>Website is a very popular medium for finding information. Building a website requires a lot of component files which will be stored on the server. To minimize website hacking, security is needed from the system side and the user side. Based on OWASP's TOP 10, one of the vulnerabilities that usually appears is the leakage of sensitive information due to the versioning file residing on the server. In order to minimize the leakage of sensitive information from these vulnerabilities, the authors created a Versioning Catcher Software (VCS) program which functions to detect the presence of these versioning files. The purpose of this research is to protect and prevent sensitive information from being leaked on the server. The results of the discussion of this research can be used to minimize the occurrence of server hacks as a result of the versioning file containing sensitive information that is not handled immediately.</em></p> 2021-07-19T00:03:44+07:00 ##submission.copyrightStatement## Perancangan sistem informasi penyimpanan data koperasi berbasis web 2021-07-19T00:18:11+07:00 Bryan Adha Elang Praditya Yessica Nataliani Penidas Fiodinggo Tanaem <p>Cooperation as one of the driving wheels of the economy also require technology in the implementation of their operations. The application of the information system to the cooperation will affect the cooperative's performance. The Tani Makmur Cooperation in Klaten is a cooperative that helps farmers in managing rice fields, but does not yet have a web-based system that can integrate the required information. In this study, a web-based information system was designed that can be used as data storage, using a waterfall model. Data were collected by observation, interviews, and SWOT analysis. The resulting information system consists of the menu Master Data, Transactions, Reports, Settings, Graphics, Backups, and Help. Cooperation members can carry out storage, borrowing and installment transactions through the Transaction menu. The cooperation admin can view all transactions through the Reports menu. The resulting web-based information system can be used to store cooperation data, thereby expediting and accelerating the transaction process for Koperasi Tani Makmur customers and also reducing the risk of data loss..</p> 2021-07-19T00:17:49+07:00 ##submission.copyrightStatement## WebShell implementation and modification for website-based attack monitoring 2021-07-19T00:42:01+07:00 Paulus Miki Resa Gumilang Dian Widiyanto Chandra <p><em>Backdoor is code commonly used by hackers to gain access to a web page illegally, backdoor or commonly called a web shell is currently used by hackers to attack a web page, but in handling attacks that use a web shell. not always detectable quickly it even takes months to realize a web page has embedded a web shell. To deal with this problem, we need an application that can quickly detect attacks carried out by embedding a web shell on a web page. The purpose of this research is to modify the existing web shell so that it can be monitored when it is used by hackers to attack a website. The monitoring process is carried out using a web page created by the author. The results of the discussion of this study are expected to reduce losses arising from attacks carried out by hackers using a web shell.</em></p> 2021-07-19T00:41:47+07:00 ##submission.copyrightStatement## Analisis kualitas website Badan Pusat Statistik (BPS) menggunakan metode WebQual 4.0 dan Importance – Performance Analysis (IPA) 2021-09-09T16:30:22+07:00 Monica Adelya Putri Kartika Gianina Tileng <p><em>The need for data usage in today's era is growing along with the growing interest of researchers and students in doing their assignments. One website that provides reliable statistical data is the Badan Pusat Statistik (BPS). The data searching process requires more time and accuracy. Therefore, the appearance and quality level of a website is considered important factors. A website that is easy for users to understand will greatly help the data search process to be more effective. In this study, the author used WebQual 4.0 and IPA methods by taking researchers who have used the BPS website as this research respondents. Data is collected using online surveys and interview techniques. This study aims to determine the importance level score and the level of performance in the Usability, Information Quality, and Service Quality factors on the BPS website and also map the results of data retrieval into the Cartesian quadrant.</em></p> 2021-09-09T16:29:36+07:00 ##submission.copyrightStatement## Sistem optimasi pendistribusian bahan makanan dan snack dengan algoritma Ant Colony Optimization (ACO) 2021-10-11T02:20:40+07:00 Lutfi Erik Prasetyo Istiadi Istiadi Fitri Marisa <p><em>Distribution activities are activities of distributing goods and services made from producers to consumers so that news is famous. That's what the company CV. Landahur, this company is responsible for implementing food and snack ingredients from the principal to the customer. This is done so that it makes it easier for customers and producers to buy and sell. In the distribution process, a salesman will make visits to customers with the aim of selling these food ingredients and snacks, but with so many customers who need to be visited, the best route recommendation is recommended. In this study, using the Ant Colony Optimization (ACO) algorithm. ACO is used because it is able to show the best route with parameters. In this study, 2 trials were carried out, the first trial using 5 data obtained a distance of 20.3 km and the second trial using 10 data obtained the best route distance of 22.96 km with the parameter that the number of ants is 3, 2iterations, α = 1, β = 0 , 5, ρ = 0.5194, the initial Pheromone = 0.1. With this system, it is hoped that it can help sellers get the best route information precisely and accurately.</em></p> 2021-10-11T02:19:45+07:00 ##submission.copyrightStatement##
