PENGARUH DISPOSISI MATEMATIKA TERHADAP HASIL BELAJAR SISWA SMA DALAM PEMBELAJARAN DI INSTAGRAM
AbstractMathematical disposition is one of the most studied variables in offline learning. When online learning is carried out, this variable is often forgotten because of the difficulty of capturing this phenomenon in learning. This variable is needed to improve the quality of mathematics learning in class and student learning outcomes. This study aims to find the effect of students' mathematical disposition on learning outcomes in learning with the Instagram (IG) platform. The research was conducted in class XI IPA SMAN 15 Bandar Lampung using the causal method and the research population was 282 people. The variables in this study were students' mathematical disposition (X) and students' mathematics learning outcomes (Y). The data were obtained through a questionnaire instrument for students' mathematical dispositions and a mathematical test instrument. Hypothesis testing is done by a simple linear regression test using = 0.05. The regression equation is obtained = 35.811 + 0.026X with = 0.09. The significance value of mathematical disposition is 0.048 (i ) so it can be concluded that there is an influence of mathematical disposition on the understanding of mathematical concepts of class XI students of SMAN 15 Bandar Lampung.Keywords: instagram; learning outcome; mathematical disposition AbstrakDisposisi matematika merupakan salah satu variabel yang banyak diteliti dalam pembelajaran offline.

Relationship between Family Social Support and Quality of Life for Hypertensive Elderly in Tenggela Village, Tilango District
The elderly have problems related to aspects of decreased physical function, namely a decrease in body systems and a decrease in the ability of the five senses that affect activities. The decrease in the physical condition of the elderly causes a decrease in the efficiency of cardiovascular homeostatic mechanisms, including hypertension. The design of this study used an analytic survey with a cross sectional approach, sampling using total sampling, obtained 58 respondents, then given a questionnaire. The results showed that the p value was 0.001 (p <0.05), which means that there is a significant effect. It can be concluded that there is a relationship between family social support and the quality of life of the elderly with hypertension. So it is hoped that the increase in family social support for the elderly so that they are able to face a happy and optimistic old age
SISTEM INFORMASI E-RAPORT BERBASIS WEB MENGGUNAKAN METODE PROTOTYPE (STUDI KASUS PADA SMPN 2 WAGIR KABUPATEN MALANG)
SMPN 2 Wagir School has used an excel-based desktop E-RAPORT. This system only covers about value processing. The process of entering values uses excel. Therefore, the author developed a website-based E-RAPORT system to facilitate the value processing process. The research uses the prototype model where this method is centered on presenting to users. The use of a systemized value processing application is able to cut the processing time of value data to be faster. The measurement of the feasibility level of the application was carried out by testing UAT (User Acceptence Test) which got very good results with an average percentage of 91% from 3 aspects of assessment
