ABSTRAK
Tujuan penelitian ini adalah mengetahui (1) hasil setiap tahapan pengembangan modul termokimia berbasis problem solving untuk siswa SMA kelas XI semester 1 Kurikulum 2013 (2) kelayakan modul termokimia berbasis problem solving yang dikembangkan berdasarkan validasi ahli, penilaian praktisi dan respon siswa (3) keefektifan modul termokimia berbasis problem solving yang dikembangkan untuk meningkatkan prestasi belajar siswa SMA kelas XI semester 1 Kurikulum 2013.
Penelitian ini mengadaptasi prosedur pengembangan Borg & Gall yang disederhanakan menjadi sembilan tahapan. Uji coba skala kecil dan uji coba operasional dilaksanakan di SMAN 1 Girimarto, SMAN 1 Jatisrono dan SMAN 1 Sidoharjo dengan subyek 16 siswa untuk uji skala kecil dan 154 siswa untuk uji coba operasional. Uji coba lapangan utama dilakukan di SMAN 1 Girimarto dengan kelas XI MIA 1 sebagai kelas eksperimen dan kelas XI MIA 2 sebagai kelas kontrol. Kelayakan modul diperoleh dari penilaian validator ahli, praktisi dan respon siswa melalui angket menggunakan skala Ordinal dengan skor 1 sampai 5. Efektivitas modul diperoleh dari analisis uji-t perbedaan rata-rata gain score hasil tes pengetahuan, rata-rata penilaian ketrampilan, dan sikap pada uji lapangan utama di kelas eksperimen dan kelas kontrol.
Hasil penelitian menunjukkan bahwa: (1) hasil dari setiap tahapan pengembangan dimulai dari studi pendahuluan diperoleh informasi untuk dikembangkan bahan ajar yang sesuai dengan karakter siswa dan kebutuhan pembelajaran yang sesuai dengan Kurikulum 2013 sehingga dikembangkan modul termokimia berbasis problem solving (2) modul termokimia berbasis problem solving yang telah dikembangkan sangat layak digunakan dalam pembelajaran siswa SMA kelas XI semester 1 Kurikulum 2013 berdasarkan validasi ahli, penilaian praktisi dan respon siswa dengan persentase sebesar 83,87% (3) modul termokimia berbasis problem solving efektif meningkatkan prestasi belajar pengetahuan, sikap dan ketrampilan siswa.

ABSTRACT
The purposes of the research were to know: (1) the result of each step of the development thermochemistry module based on problem solving for class XI of SMA/MA students according to curriculum 2013 (2) the feasibility of thermochemistry module based on problem solving obtained from validation by experts, practitioners, and the students responses (3) the effectiveness of thermochemistry module based on problem solving for class XI of SMA/MA students according to curriculum 2013.
This study adapted the Borg & Gall development procedures were simplified into nine stages. Initial field test and operational fields test conducted in SMAN 1 Girimarto, SMAN 1 Jatisrono and SMAN 1 Sidoharjo with 16 students subject to initial field test and 154 studens for operational fields. The main field test conducted in SMAN 1 Girimarto with class XI MIA 1 as experiment class and class XI MIA 2 as control class. The feasibility assessment module obtained from validation by experts, practitioners, and the students responses through  questionare using ordinal scale from 1 to 5. The effectiveness module is obtained from independent sample t-test of the difference in average gain knowledge test scores, the average assessment skills, and attitudes on the main field test in the experimental class and the control class.
The results of research and development were: (1) the result of each step showed that from preliminary study got information to make teaching materials based on student characters and needs analysis according curriculum 2013 that’s developed thermochemistry module based on the problem solving (2) thermochemistry module based on the problem solving is worthy used for learning class XI SMA/MA semester 1 curriculum 2013 based on validation experts, practitioners, and students with percentage of 83.87% (3) thermochemistry module based on the problem solving effectively improve learning achievement of knowledge, attitudes and skills of students.
Key words: Module, Problem Solving, Thermochemistry, Curriculum 2013
