Normal range of TSH for adult is from 0.3 to 5.5 µIU/ml, whereas for baby ranged from 3 to 18 µIU/ml. An Immunoradiometricassay (IRMA) is one of immunoassay technique using radionuclide as the tracer to detect low quantity of analyte. This technique is suitable for determine TSH levels in human blood serum which has complex matrix and various concentration. The Center for Radioisotope and Radiopharmaceutical Technology (CRRT)-BATAN has developed a reagent of TSH IRMA kit. The aim of this research is to compare between local TSH IRMA kit (CRRT-BATAN) and imported TSH IRMA kit (Riakey, Korea) toward 110 adult samples obtained from PTKMR - BATAN. The results showed 97 samples as true negative, 5 samples as true positive, 1 sample as false negative and 7 samples false positive.

This study was conducted on 10th-grade students in the academic year of 2016/2017. Collaborative learning, as well as the use of real-life scenario, are some of the teaching practices for facilitating Social Emotional Learning (SEL) and promotes students' social-emotional competenciesthat aligned with affective competencies in Indonesia’s 2013 curricula. The proposed teaching practices also answer the challenges faced by the implementation of the 2013 curricula, finding proper teaching practices to integrate to develop student’s character through learning activity. The empirical work of the study is based on a qualitative approach. Six Group Investigation’s stage integrated with the use of real-life scenario was analyzed through various method such as observations, interviews, reflective journals, and student’s worksheets answer.
