This research aims to find out the usefulness of an android-based ToSM (test of second mathematics) instrument for mapping the competency of intuitive basic calculation (CIBC) in students. ToSM (Test of Second Mathematics) is the standard instrument of Mathematics Seconds to measure IBCC (Intuitive Basic Calculation Competencies). ToSM only covers arithmetic operations (addition, subtraction, multiplication, and division), most essential. ToSM measures the number of operation counts per minute (OPM), time per operation category completion. The method used in writing review literature begins with the selection of topics. It then determines the keywords for the search for journals so that several journals are selected to be analyzed. Searches for the journal through google scholar are limited from 2015 to 2021. Meanwhile, the keyword used is "ToSM Seconds Mathematics." This research was conducted by reviewing journals or literature related to this study plus statistical data and scientific works related to ToSM, which the Center for The Development of Mathematics Seconds (CDMS) team updates. Mapping essential calculation competencies among students are no less critical because ToSM has other uses, namely as an instrument to train concentration and resilience in learning.

<p>Penelitian ini bertujuan untuk membuktikan: adanya efektivitas diagnosis dan habituasi metode ToSM level A1 bilangan asli terhadap kompetensi hitung dasar intuitif untuk operasi tambah, kurang, kali dan bagi. Kompetensi hitung dasar intuitif adalah kemampuan kognitif (pengetahuan) dan keterampilan mengoperasikan hitung dasar secara intuitif. Peneliti mengambil sampel dengan menggunakan teknik total sampling atau sampel jenuh. Selain itu untuk teknik analisis data yang digunakan yaitu Uji Anava dan Uji Independent Sample T Test serta uji signifikansi dan linearitas. Adapun hasil uji hipotesis uji T terdapat perbedaan hasil antara pretest dan posttest ToSM pada mahasiswa tingkat akhir dengan habituasi aplikasi ToSM selama 15 hari. Kesimpulan penelitian ini menghasilkan kesimpulan bahwa metode ToSM level A1 efektif sebagai alat diagnosis hitung dasar intuitif pada subjek penelitian dengan bukti masih ada mahasiswa yang belum memiliki kompetensi hitung dasar intuitif yakni kurang dari 30 OPM, sekaligus efektif terhadap peningkatan kompetensi hitung dasar intuitif.</p><p> </p><p><strong><em>Kata kunci:</em></strong><em> Diagnosis, Habituasi, Metode ToSM, Kompetensi hitung dasar intuitif</em></p>

This study aims to empirically test the influence of adversity quotient on the achievement of ToSM (test of second mathematics) scores on the student. The hypothesis proposed is the influence of adversity quotient on the accomplishment of ToSM scores on students. The subjects in this study amounted to 34 students from SMK Negeri 1 Dukuhturi, Tegal Regency. The sampling technique used is saturated sampling. The measuring instruments in this study were adversity quotient scales and Android app-based ToSM. The results of this study showed the significance of the correlation test was 0.671 > 0.05 and Pearson correlation = 0.075 < r table = 0.3246, while the linearity test explained the magnitude of the correlation value / R relationship of 0.75 of the output obtained a coefficient of determination (R Square) of 0.006, which contains the understanding that the influence of Adversity Qutotien variable on variable performance ToSM score value is 0.6%, the data can be interpreted that there is no correlation between the variables studied, these findings can also be interpreted that to increase KHDI is not enough just by relying on adversity intelligence alone need other efforts.
