<![CDATA[Students' mathematics learning outcomes who low are associated with several factors. Students learning interest, parental supervision, and students' perception of the learning environment at school are several factors that probably related to learning outcomes. The purpose of this research is to know whether existing or not a positive relationship and significant between students learning interest, parental supervision, and students perception to learning environment at school with students mathematics learning outcomes in class X TKR (Teknik Kendaraan Ringan) SMK Negeri 1 Seyegan, Sleman District in odd semester in academic year of 2016/2017. The population in this research was a student of class X TKR SMK Negeri 1 Seyegan, Sleman District in the odd semester in the academic year of 2016/2017 who consisting of class X of TKR 1, X of TKR 2, and X of TKR 3 with total 96 students. Sample taken class X of TKR 3 as a research class sample with random sampling to the class. Technique to collect the data uses the chief to obtain students learning interest, parental supervision, and students' perception of learning environment data at school, and a method of test to obtain data of mathematics learning outcomes. Research instruments test: validity test, different power test, and reliability test. The prerequisite analysis test include normality test, linearity test, and independence test. The data analysis use product moment analysis and multiple linear regression analysis to analyze the data. The research results showed that there was a positive and significant relationship between students learning interest, parental supervision, and students perception to learning environment at school with students mathematics learning outcomes in class X TKR (Teknik Kendaraan Ringan) SMK Negeri 1 Seyegan, Sleman District in odd semester in the academic year of 2016/2017.
