<![CDATA[This study aims to validate the video-based teaching materials that have been developed. Three material experts and three media experts conducted a feasibility test of video-based teaching materials using cube and block building materials, using pre and post tests to determine the effectiveness of the material. this instructional video and student answers. The subjects in this study were 31 class VIII students of SMP N 5 Bilah Barat. This study uses the ADDIE approach for development research (R&D). The research instruments included material and media expert validation sheets, pretest and posttest questions, and student answer surveys. These results obtained data validation from material experts 81.66% (Very Eligible), media experts 86.11% (Very Eligible), an increase in pretest-posttest results 0.51% in the medium category, and student responses accounted for 88.06% of total (Strongly agree). The results of the validation of video-based teaching materials assisted by Sparkol Videoscribe for learning mathematics show that teaching materials are very suitable for use as teaching materials in learning mathematics.]]>

<![CDATA[This study aims to improve students' mathematical reasoning abilities through the Integrated Problem Solving learning model in a scientific approach with the help of geogebra for class X students of SMA Bina Bersaudara Medan. The subjects in this study were 47 students of X-MIA class at Bina Bersaudara Private High School Medan. From the initial ability test, it was obtained that the average score of students was 2.41 which was included in the low category and 42.55% who completed. After being given action in cycle I and given a mathematical reasoning ability test, it was obtained that the average score of 2.79 students was included in the moderate category (53.19%) who passed. In cycle I, the percentage of completeness of mathematical reasoning had not been achieved, so cycle II was carried out. After being given action in cycle II and given a mathematical reasoning ability test, an average score of 3.03 was obtained in the good category and 87.23% had completed. From cycle I to cycle II, an increase in the average score and the percentage of mathematical reasoning completeness were obtained.]]>

<![CDATA[A common problem that often occurs in the elderly is sleep disturbance which can affect quality of life. One of the most common sleep disorders is insomnia. This study aims to analyze the impact of the benson relaxation technique on the level of insomnia in the lederly. This research is a quantitative study with a one group pretest-postest (pre-experimental study) design. The number of samples in this tudy were 30 respondents with a sampling technique using total sampling. The data collection tool used a questionnaire consisting of a survey of respondent characteristics and an insomnia rating scale. The intervension used is the benson relaxation technique. Data collection was carried out before and after the implementation of the intervention. Research data were analyzed using the wilcoxon signed-rank test with a p-value <0.05. The conclusion in this study is that there is a significant difference in the level of insomnia in the elderly between before and after the implementation of the intervention.]]>

<![CDATA[Securing data is one of the things that is very important to protect the contents of the data from parties who can harm it by destroying important data from the owner. This study applies two algorithms, namely the RSA algorithm and the One Time Pad algorithm. First use the RSA algorithm first with predetermined plaintext. After finishing working on the RSA algorithm, then continue working on the same plaintext as the One Time Pad algorithm. The results of the study show that the application of the RSA and One Tome Pad algorithms, the level of security of document files and text messages can be better maintained for the authenticity of the data. So that data leakage can be minimized.]]>

<![CDATA[The purpose of this research is to examine the effect of profitability on firm value with firm size as a moderating variable. The population for this research is the industrial sector listed on the IDX in 2019-2021. The sampling technique used purposive sampling and obtained a number of 63 observational data from 21 companies. The data analysis technique uses multiple linear regression analysis with the Moderated Regression Analysis (MRA) test using the SPSS 25 program. The results of this research prove that profitability has a positive effect on firm value with a magnitude of 331.224. Meanwhile, company size is able to moderate the influence of profitability on firm value in a negative direction, which means it weakens with a magnitude of -12.252.]]>
