Abstract

Two-dimensional repetitive and symmetrical patterns are found in everyday life, such as in cloth motifs, decorative art, road pavement design, and floor tiles. 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 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.

Abstract

Reward and punishment are needed for assessting employees’ performace. Employee grouping based on their performance is one of several ways to enhance employees’ performance. This research discusses about grouping employess based on their performance using Fuzzy C-Means. Result from assessment comes from the total of each criteria that contains of presence, discipline, and task duration. Three groups of employees are formed, which are good, moderate, and bad. From 13 employees, 10 of them are in the good criteria, one is in moderate criteria, and two are in the bad one. We also use different values of fuzzy exponent to get the clustering results. The values 1.5 and 2 of fuzzy exponents give the same clustering results with the result from manager. Therefore, grouping with FCM could be used to cluster employees based on their performance.

Abstract

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..

Abstract

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.

Abstract

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.
