Tujuan penelitian ini untuk mengetahui dan menganalisis pengaruh penerapan teknik rileksasi progresif jacobsen dan latihan konsentrasi software schulte terhadap peningkatan kemampuan konsentrasi siswa. Kemampuan konsentrasi pada siswa bersifat fluktuatif, untuk itu perlu ditingkat kemampuan konsentrasinya agar proses pembelajaran dapat berjalan dengan efisien. Kemampuan konsentrasi dapat ditingkatkan melalui banyak cara diantaranya teknik rileksasi jacobsen penerapan dengan software schulte, akan tetapi belum banyak peneliti yang menganalisis besar pengaruh terhadap kemapuan konsentrasi siswa. Metode yang digunakan adalah metode ekperimen dengan menggunakan desain Pre-postest Group Design. Populasi pada penelitian ini adalah siswa siswi kelas VII dan VIII SMP Negeri 9 Bandung. Sampel pada penelitian ini adalah 70 siswa. Teknik pengambilan sampel menggunakan Proportionate Stratified Random Sampling yang dibagi ke dalam dua kelompok yaitu 35 siswa ke dalam rileksasi Jacobsen, dan 35 siswa pada kelompok latihan konsentrasi. Ringkasan hasil penghitungan hasil paired t-test hipotesis 1 adalah (11,14±3,55) vs (16,85±3,48) dengan p-value 0.000**, hipotesis 2 adalah (13,40±2,92) vs (18,45±3,53) dengan p-value 0,000**, hipotesis 3 (5,71±4,61) vs (5,06±3,15) beda pengaruh 12,85% dengan p-value 0,488. Kesimpulan 1) terdapat peningkatan kemampuan konsentrasi sebesar 51,23% dengan menerapkan teknik rileksasi otot progresif Jacobsen; 2) terdapat peningkatan kemampuan konsentrasi 37,69% dengan menerapkan software schulte; 3) tidak ada perbedaan kemampuan konsentrasi antara penerapan teknik rileksasi otot Jacobsen dengan penerapan software schulte. ABSTRACTThe purpose of this study was to determine and analyze the effect of the application of jacobsen’s progressive relaxation techniques and schulte software concentration training on improving students' concentration ability. The concentration ability on students is fluctuating, so it is necessary to increase their concentration ability so that the learning process can be efficiently. Concentration ability can be improved through many ways, such as applying jacobsen relaxation techniques and schulte software, but not many researchers have analyzed the influence of students' concentration. The method used is the experimental method using the pre-postest group design. The population in this study were students of middle scholl at 7th and 8th classes in Bandung. The sample in this study were 70 students. The sampling technique used proportional stratified random sampling which was divided into two groups: 35 students into Jacobsen's relaxation, and 35 students in the concentration training group. Summary of the results of the calculation of the results of paired t-test in the 1st hypothesis is (11.14±3.55) vs (16.85±3.48) with p-value 0.000**, 2nd hypothesis is (13.40±2.92) vs (18.45±3.53) with p-value 0.000**, 3rd hypothesis is (5.71±4.61) vs (5.06±3.15) difference in influence 12.85% with p-value 0.488. Conclusion first, there was significant an increased in concentration ability of 51.23% by applying Jacobsen's progressive muscle relaxation technique; second, there was significant an increased in the ability to concentrate 37.69% by applying schulte software; 3) there was no significant difference in concentration ability between the application of Jacobsen's muscle relaxation technique and the application of schulte software.
