Abstract

Matematika sekolah merupakan mata pelajaran yang dipelajari pada setiap jenjang pendidikan. Pada pembelajarannya ditemukan permasalahan kemampuan komunikasi lisan matematis siswa masih rendah. Selain itu, materi garis singgung juga dianggap sulit oleh siswa. Sampel penelitian ini adalah siswa kelas VIIIB, VIIIC, dan VIIID SMP Negeri 2 Demak. Kelas eksperimen adalah kelas VIIIE yang menggunakan pembelajaran Missouri Mathematics Project (MMP). Teknik pengumpulan datanya dengan tes tertulis, pengamatan, dan tes lisan. Instrumen yang digunakan adalah soal tes, lembar pengamatan, dan lembar penskoran tes lisan. Hasil penelitian menunjukkan rata-rata skor kemampuan komunikasi lisan matematis siswa pada kelas eksperimen telah mencapai minimal skor ketuntasan individu. Berdasarkan pengujian proporsi diperoleh hasil kelas eksperimen telah mencapai ketuntasan klasikal. Hasil tersebut diperkuat dengan hasil uji perbedaan rata-rata. Rata-rata perolehan skor kemampuan komunikasi lisan matematis siswa kelas eksperimen lebih tinggi jika dibandingkan dengan kelas kontrol. Dari hasil pengolahan data dengan SPSS 17.00 for windows diperoleh rata-rata perolehan skor kemampuan komunikasi lisan matematis kelas eksperimen adalah 32,5 sedangkan untuk kelas kontrol 22,2667. Berdasarkan hasil penelitian dapat disimpulkan bahwa pembelajaran Missouri Mathematics Project (MMP) efektif pada pencapaian kemampuan komunikasi lisan matematis siswa.

Abstract

Medical laboratory services can support disease diagnosis or monitor patient recovery. The reality of the POCT method has been widely used by clinical laboratories. The tool is not only used for screening but is also used to check the diagnosis of diabetes mellitus. This research aims to determine the validity of the POCT method on whole blood, serum, and plasma EDTA samples on blood glucose tests. The research method of this study used the descriptive-analytical method using the POCT method on blood glucose tests using three different types of samples, whole blood, serum, and plasma EDTA. Precision tests were accepted on normal and pathological serum samples with CV% of 2.02% and 2.27%. The accuracy test was accepted on a normal and pathological serum with TE% values ​​of 8.54% and 6.03%. The linearity test is accepted on serum–plasma EDTA samples with an r2 value of 0.998. The sigma values ​​are in the unacceptable area. The use of the POCT tool for blood glucose examination has a valid performance value. The deviation of the examination results is influenced by pre-analytical errors such as sampling and processing samples so that the total error obtained is higher than the total allowed error. The POCT tool can be used for all types of samples.
