Tujuan penelitian (1) mendiskripsikan peningkatan minat belajar pada kubus dan balok melalui penerapan strategi pembelajaran Mastery Learning With Quiz Team, dan (2) mendiskripsikan peningkatan hasil belajar pada kubus dan balok melalui penerapan strategi pembelajaran Mastery Learning With Quiz Team. Jenis penelitian PTK kolaboratif. Subyek penelitian yang dikenai tindakan adalah siswa kelas VIII G SMP Negeri 3 Kartasura, yang berjumlah 33 siswa. Metode pengumpulan data, metode observasi, wawancara, catatan lapangan, tes dan dokumentasi. Teknik analisis data secara deskriptif kualitatif dengan metode alur. Keabsahan data dilakukan dengan observasi secara terus menerus dan triangulasi data. Hasil penelitian ini menunjukkan bahwa: (1) adanya peningkatan minat belajar siswa dapat dilihat dari meningkatnya indikator banyaknya siswa yang: a) mau menjawab pertanyaan dari guru sebelum tindakan 12,12%, putaran I 28,13%, putaran II 41,94% dan di akhir tindakan 62,50%, b) mau bertanya kepada guru sebelum tindakan 9,09%, putaran I 21,88%, putaran II 38,71% dan di akhir tindakan 50%, c) mau maju mengerjakan latihan soal di depan kelas sebelum tindakan 6,06%, putaran I 12,50%, putaran II 32,26% dan di akhir tindakan 53,13% dan (2) ada peningkatan hasil belajar siswa yang mendapat nilai lebih dari nilai KKM yaitu 68 sebelum tindakan 24,24%, putaran I 40,63%, putaran II 70,97% dan di akhir tindakan 93,75%. Kesimpulan penelitian ini adalah bahwa (1) penerapan strategi Mastery Learning With Quiz Team dapat meningkatkan minat belajar siswa dan (2) penerapan strategi Mastery Learning With Quiz Team dapat meningkatkan hasil belajar siswa

Transcatheter Closure of Perimembranous Ventricular Septal Defect Using the Lifetech Konar-Multi Functional Occluder: Early to Midterm Results of the Indonesian Multicenter Study

Background: The alternative device to close perimembranous ventricular septal defect (pmVSD) has been searched for better result, less complications and applicable for infants. However, the ideal device is still unavailable. We aimed to evaluate the effectiveness and outcome of transcatheter pmVSD closure using the KONAR-multi functional occluder (MFO). Methods: Clinical, procedural, follow-up data of pmVSD patients with symptom of heart failure or evidence of significant left to right shunt, growth failure, recurrent respiratory tract infection, and history of endocarditis who underwent transcatheter closure using the MFO were prospectively evaluated. Results: Between January 2016 and December 2017, there were complete records of 132 pmVSD children closed using MFO from eleven centers in Indonesia. The median of age was 4.5 (0.3-17.4) years; weight 14.8 (3.5-57) kg, defect size at the smallest part 3.4 (1.0-8.1) mm, flow ratio 1.6 (1.3-4.9), mean pulmonary artery pressure 18 (7-79) mmHg, fluoroscopy time 18 (3.8-91) and procedural time 75 (26-290) minutes. A retrograde approach was done in 41 (31%) patients. Procedures succeeded in first attempt in 126 (95.4%), failed in three and migration in three patients. Six of eight infants with congestive heart failure were closed successfully. Of 126 patients with successful VSD closure, 12 months follow-up were completed in all patients. The rate of complete occlusion at 1 month, 3 months, 6 months and 12 months after intervention were 95.2%, 97.6%, 99.2%, and 99.2%, respectively. New-onset aortic regurgitation and moderate tricuspid regurgitation developed only in five and three patients. Neither complete atrioventricular block, nor other complications occurred. Conclusion: Transcatheter closure of pmVSD using the MFO is safe, effective, and feasible in infants and children
