 Abstrak___________________________________________________________________Pada proses pembelajaran di sekolah masih ditemui siswa yang tidak dapat meraih hasil belajar yang setara dengan kemampuan inteligensinya. Ada sekitar 20% siswa yang mempunyai kemampuan inteligensi tinggi tetapi memperoleh hasil belajar yang relatif rendah, serta ada pula siswa yang walaupun kemampuan inteligensinya relatif rendah namun dapat mengelola emosi dan berkomunikasi dengan baik sehingga dapat meraih hasil belajar yang relatif tinggi. Oleh sebab itu, dalam proses belajar siswa keseimbangan antara kecerdasan inteligensi, emosional dan spiritual sangat diperlukan. Penelitian ini bertujuan untuk mengetahui apakah ada hubungan antara Emotional Quotient(EQ) dengan hasil belajar siswa domain kognitif, afektif dan psikomotor pada materi pengelolaan lingkungan. Penelitian ini adalah penelitian korelasional. Populasi dalam penelitian ini adalah siswa kelas VII SMP Negeri 29 Semarang dan sampel yang digunakan adalah 71 siswa yang diambil dengan teknik proporsional random sampling. Data diambil dengan instrumen angket kuesioner, tes dan praktikum untuk kemudian dianalisis dengan uji korelasi. Hasil dari uji korelasi menunjukkan bahwa hubungan antara Emotional Quotient(EQ) dengan hasil belajar siswa domain kognitif yaitu dengan koefisien korelasi 0,336,  hasil belajar siswa domain afektif dengan koefisien korelasi 0,556 serta hasil belajar psikomotor dengan koefisien korelasi 0,381 sehingga menunjukkan ada hubungan antara Emotional Quotient (EQ) dengan tiga domain hasil belajar siswa pada materi pengelolaan lingkungan. Hal ini berarti bahwa semakin tinggiEmotional Quotient (EQ), maka akan semakin baik pula hasil belajar kognitif, afektif dan psikomotor siswa pada materi pengelolaan lingkungan.  Abstract _________________________________________________________________ Process of teaching and learning in schools still found students who can not achieve the learning outcomes equivalent with intelligence capabilities.
