Abstract

The perception of many students that mathematics is known to be difficult has made the experience negative, so that it has a general impact when adjusting to meeting material calculations. One of the basic materials of mathematics is geometry. This material has provided experiences for Elementary School (SD) children at grade 2 (two) to grade 4 (four). So, one solution is to play with Geometry Space. One of the android-based educational games that provides a media for self-adjustment in understanding material from Geometry. This study designed the Fisher-Yates algorithm in an educational game based on android which is named "Ruang Geometri". An algorithm that will help in randomizing the questions on the "Ruang Geometri" quiz. The purpose of this game is to change students' perceptions to be positive about mathematics because it is no longer a scary subject but fun. The results of this study are to recognize flat and space shapes in the form of educational games.Keywords:Mathematic; Educational Game; Fisher-Yates Algorithm.

Abstract

The emergence of a habit in Indonesia and even the world, namely the use of used clothes (thrifting) became the idea for this research. This new habit is known to be able to reduce the production of textile waste in the world. The purpose of this study was to obtain analysis results that affect the use of new clothes (fast fashion) on the use of used clothes (thrifting). Using the K-means Clustering method and using several parameters, including age, quality, price, and sustainability or awareness. The method of collecting data is through a questionnaire and the research material is the buyers found in the online store Instagram (thriftboys.id). From the results of the clustering process that researchers have done using the K-means algorithm with manual calculations and rapidminer applications, the conclusions consist of; 1) In clusters 1 and 2 the age factor shifting from fast fashion to thhirft is 23 years, while in cluster 3 it is 25 years, 2) In the three clusters the average income that shifts from fast fashion to thhirf is group 3 or the range of 200000 -500000, 3) In the third cluster, people switch from fast fashion to thrift because of the good quality of goods, and 4) In clusters 2 and 3 more people are aware of textile waste for the world.

Abstract

Along with the current development of digitalization technology, almost all aspects have adapted to these changes, including the Indonesian people, who are mostly traders, also take part in this development. The website is one of the digitalization models that is often used in promoting products, both goods and Services, in this case the author takes one example, namely the sale of a flower shop "Bunds Flowers" where in this case the flowers that are sold are not like flowers in general, but there are flowers in the type of paper, plastic, to imported and local flowers, making this flower shop very worthy of having more promotional value, both in terms of conventional (face-to-face) and modern (online/digitalized) sales. This study uses two methods where the waterfall method is applied to the system development process and the PIECES method to analyze the user's response to the system that has been built. In this journal the author aims to build a system where sales and ornamental plant enthusiasts still use traditional media, with the websites help consumers find what they need in an easy way by opening a website. In the analysis process, the respondents have produced several assessments related to the flower shop application, including 1) performance, respondents rated 3.73 (Satisfied) 2) Information, respondents rated 4.33 (Satisfied), 3) Economic, respondents rated 4.33 (Satisfied) , 4) Control and Security, respondents rated 4.10 (Satisfied) and 5 Efficiency, respondents rated 3.73 (Satisfied) and Service, respondents rated 3.73 (satisfied).

Abstract

General elections are basically still carried out conventionally, namely by using paper media in voting. This will lead to weaknesses in the calculation of votes such as a waste of money and time. This study aims to develop a website-based e-voting information system in the general election for the chairman of the RW which is expected to minimize the weaknesses of conventional elections. This system was developed to make the voting process more efficient and easy to use. This application is designed using the PHP programming language and MySQL database, using the waterfall method. By doing black-box testing, it is hoped that the e-voting system can run well functionally without any error, and dummy variable testing to determine the influence of voters in selecting candidates based on graduation rate.
