Abstract

The objective of this study is to apply cluster analysis or also known as clustering on stocks data listed in LQ45 index at Indonesia Stock Exchange. The problem is that traders need a tool to speed up decision-making process in buying, selling and holding their stocks.The method used in this cluster analysis is k-means algorithm. The data used in this study were taken from Indonesia Stock Exchange. Cluster analysis in this study took data’s characteristics such as stocks volume and value. Results of cluster analysis were presented in the form of grouping of clusters’ members visually. Therefore, this cluster analysis in this study could be used to identify more quickly and efficiently about the members of each cluster of LQ45 index. The results of such identification can be used by beginner-level investors who have started interest in stock investment to help make decision on stocks trading.

Abstract

The aim of the study was to examine the relationship between the relationship between instructional videos and students' understanding of the learning material. Researchers create digital learning materials through video material (VBL), especially math in RPTRA. The researchers used correlation analysis to examine the relationship between the learning material in video form and the level of understanding of the students in the material. The method used by the researcher was to experiment with elementary-level children from various primary schools. Then, based on the experimental results, the correlation analysis test was performed to see the relationship between the student's understanding and the learning material through video. From the results of the assessment, it can be seen that the video material can help the understanding of the students and can also increase the motivation of the students in learning mathematics. Therefore, video learning can help students understand mathematics and help teachers teach mathematics in a more interesting way.

Abstract

Indonesia is the largest archipelago country in the world consisting of 17,499 islands from Sabang to Merauke. With so many areas in Indonesia that has so many areas scattered and, in every place, has a place for Public Fuel Filling Station (SPBU). With the distribution of gas stations based on regions in Indonesia, information is needed on the existence or position or location of gas stations to facilitate vehicle users to find gas stations. The aim of this research is to develop an application for gas station location instructions so that it can provide detailed information on the position and facilities at the gas station. Application development uses the waterfall approach and uses the Android programming language to build mobile applications. Evaluate application testing with the black box approach, that the application can run in accordance with the functions of each menu on the application so that the application can be used by users. This application can facilitate the user (user) in searching for locations from existing gas stations quickly and precisely and can be accessed by anyone, anytime, and anywhere.
