Jenis penelitian yang digunakan adalah Penelitian Tindakan Kelas (PTK) dengan menggunakan dua siklus pembelajaran, dengan subjek kelas X-1 SMA Negeri 1 Batangtoru yang berjumlah 25 orang. Sedangkan objek penelitian ini adalah penggunaan model pembelajaran berbasis masalah dengan Blended untuk meningkatkan kemampuan pemecahan masalah matematika siswa. Sebelum instrumen digunakan terlebih dahulu dilakukan uji coba tes untuk melihat validitas dan reabilitas tes. Dari 6 soal tes siklus I dan 6 soal tes siklus II yang diuji coba diperoleh 5 soal tes siklus I yang valid (sah) dan 5 soal tes siklus II yang valid (sah), dan semua soal tes reliable dengan koefisien reabilitas tes 0,926 dengan tingkat reliabilitas tinggi dan memiliki korelasi validasi dengan kategori sedang. Hasil rata-rata tes kemampuan pemecahan masalah matematika siswa pada tes kemampuan pemecahan masalah matematika siswa pada siklus I yaitu 68,80 pada kategori “Cukup” dengan ketuntasan 64,00% dan persentase kadar aktivitas siswa 70,31%. Kemudian melanjutkan kegiatan siklus II dimana rata-rata hasil tes kemampuan pemecahan masalah matematika siswa pada siklus II yaitu 83,04 pada kategori “Baik” dengan persentase ketuntasan 92,00% dan persentase kadar aktivitas siswa 89,06%.

The problem faced by Muslims today in a constitutional context is a complex one. A revolutionary solution is needed to answer the problem and it is certainly not enough to use the classical Islamic legal methods. When viewed in the Islamic constitution, many of the problems that arise today are textually absent from the provisions of the law. Thus, to answer these problems requires a systematic methodology and legal formulation. In answering and formulating legal provisions in contemporary cases, it can be done by the qiyas method. This study aims to formulate the qiyas methodology as the fourth constitution in Islam to answer all problems of Muslims in the context of siyasah. Various things that are the object of research are in the fields of siyasah harbiyah, siyasah dusturiyah, and siyasah maliyah. The three siyasah in the national constitutional system are known as the state defense system, the state legislative system, and the state revenue and taxation system.   To facilitate this research, the author utilizes the theory of literature research with a qualitative research approach. Researchers first formulate one problem and then collect various literature models related to the theme. Then the researcher analyzes each of these literatures to formulate qiyas formulations in the context of siyasah. The main problem in this study is how the formulation of qiyas in formulating Islamic law and how to implement qiyas in the issue of siyasah. Therefore, the results of this study can be described as showing that the formulation of qiyas must meet four pillars, namely the initial case, the initial case law, the branch case, and the 'illat law between the two cases. Then qiyas can be implemented in answering problems in the field of siyasah harbiyah, siyasah dusturiyah, and siyasah maliyah Keywords: Constitution, Qiyas, Siyasah

Mathematics is a difficult subject for some elementary school students. One of the reasons is because the teacher still uses traditional methods using textbooks and blackboards so that sometimes it doesn't attract students' interest. Teacher's role in creating a more interactive and interesting learning atmosphere is needed. GeoGebra is an application can be used as an interactive learning medium for Mathematics lessons. This community service will provide training on active learning for Elementary School level using GeoGebra at SD Swasta Islam Terpadu IQRA’. Training about GeoGebra was given to a group of teachers who teach Mathematics. The training included how to install GeoGebra application, how to create basic objects and how to make animations using sliders in GeoGebra. Furthermore, GeoGebra training can also be given to other schools as an alternative to a more interactive mathematics learning media.
