<![CDATA[Abstract: The objectives of this research are to investigate: (1) whether or not there is a significant effect of the peer group?s friendship (X1) on the learning motivation (Y) of the students in Grade X; (2) whether or not there is a significant effect of the parents? attention (X2) on the learning motivation (Y) of the students in Grade X; and (3) whether or not there is a simultaneously significant effect between the peer group?s friendship and the parents? attention on the learning motivation of the students in Grade X. This research used the descriptive quantitative research method. The population of the research was all of the students in Grade X as many as 80 students. The samples of the research was 60% or 48 out of 80 students, and were taken by using the proportional random sampling technique. The data of the research were gathered through questionnaire and documentation. They were then analyzed statistically by using the correlation and multiple regression analysis. The results of the research are as follows: (1) there is a significant effect of the peer group?s friendship (X1) on the learning motivation (Y) of the students in Grade X; (2) there is a significant effect of the parents? attention (X2) on the learning motivation (Y) of the students in Grade X; and (3) there is a simultaneously significant effect between the peer group?s friendship and the parents? attention on the learning motivation of the students in Grade X. The multiple linear regression equation is ? = -7.639 + 0.437 X1 + 0.586 X2. The relative contribution of X1 to Y is 24.58%, but that of X2 to Y is 75.42%. In addition, the effective contribution of X1 to Y is 11.71% whereas that of X2 to Y is 35.93%. Keywords: Peer group, parents? attention, motivation. ]]>
