Abstract

The geometry concept has been developed rapidly, one of them is about fractal geometry. In fractal geometry concept, it has been discussed about shapes which have fractal dimension characteristics. In fractal geometry concept, it would resulted in a look like irregular shape. But if it had been observed closer, it would found a regular shape. Self-similarity is a characteristic in fractal geometry when diferent magnifications was found. In fractal concept, a pattern would be obtained from a function itteration by an infinite repetition. One of fractal geometry application is in batik design fabrications. This idea based on equality dimension, that is both of them is in fractal dimension. In fractal geometry, it will result in a specific design by itterated function using Wolframs a program.

Abstract

Pemahaman Nilai profetik sangat penting untuk dimiliki mahasiswa untuk masa depan bangsa.Tujuan penelitian ini adalah untuk mengetahui keefektifan integrasi pembelajaran matematika dengan Al-Quran untuk meningkatkan pemahaman nilai profetik mahasiswa program studi Tadris Matematika di IAIN Salatiga. Metode penelitian ini menggunakan quasi experiment. Teknik pengumpulan data dilakukan dengan teknik purposive sampling menggunakan kuesioner. Kuesioner penelitian dikembangkan berdasarkan sintesis dari Revised Life Orientation Test (LOT-R). Analisis hasil penelitian menggunakan statistik deskriptif dengan t-test. Hasil penelitian menunjukkan bahwa integrasi pembelajaran matematika dengan al-Qur'an dapat meningkatkan pemahaman nilai profetik mahasiswa secara signifikan. Uji t antara kelompok eksperimen dan kelompok kontrol menunjukkan perbedaan 71,74% (kelompok eksperimen 77,8%, sedangkan kelompok kontrol 6,06%) dalam peningkatan pemahaman nilai profetik.

Abstract

Tujuan dari penelitian ini adalah mengetahui pengaruh banyaknya keluarga sejahtera dan banyaknya pencurian kendaraan bermotor terhadap banyaknya obyek penerimaan pajak kendaraan bermotor di Provinsi jawa Tengah. Variabel Penelitian ini terdiri dari variabel bebas yaitu banyaknya banyaknya pencurian kendaraan bermotor dan tingkat kesejahteraan masyarakat serta Variabel terikatnya adalah banyaknya objek pajak yang membayar pajak kendaraan bermotor. Dari hasil penelitian diperoleh persamaan regresi ganda dengan besar pengaruh banyaknya keluarga sejahtera dan banyaknya pencurian kendaraan bermotor terhadap banyaknya objek penerimaan pajak kendaraan bermotor sebesar 59,6%.

Abstract

Currently, the injection of computational thinking skills in education is very important because these skills are needed in dealing with technological developments. Every teacher needs to be provided with this ability with the hope that later they will be able to inject it into every student at school. This article presents empirical experiences related to the injection of computational thinking skills for madrasah (Islamic Schools) teachers in Indonesia using the Scratch program for 60 teachers. The research method used is a mix method, namely a quantitative approach (experiment) and a qualitative approach. In quantitative analysis, two classes are used, namely experimental and control classes. In the initial stage, the measurement of computational thinking ability was carried out using 15 questions. The results of this study showed an increase in computational thinking skills in the experimental class, which was also accompanied by impressions given by participants who saw positive developments and significant explorative and practical uses in learning practices.

Abstract

Penelitian ini mempunyai tujuan terkait pemahaman guru madrasah pada kemampuan berpikir komputasional sebelum maupun setelah kegiatan implementasi pelatihan scrath serta bagaimana efektivitas penggunaan teknologi scratch dalam proses pembelajaran di kelas oleh guru madrasah. Metode dalam penelitian yang akan telah digunakan adalah penelitian eksperimen  dengan desain one grup  pretest and posttest. Populasi pada kegiatan penelitian ini adalah guru madrasah di wilayah binaan kementerian agama di Kabupaten Semarang dan Kudus. Teknik sampling yang akan digunakan adalah teknik sampling incidental dimana yang akan terpilih menjadi sampel adalah guru yang akan ditugaskan oleh sekolah dalam mengikuti kegiatan pelatihan pembelajaran dengan menggunakan scratch. Selanjutnya akan digunakan uji peringkat bertanda alam mengetahui peningkatan kemampuan berpikir komputasional dengan menggunakan scratch. Hasil penelitian menyebutkan bahwa pemahaman guru sebelum mengikuti kegiatan implementasi scratch pada proses pembelajaran  sebesar 13,33. Setelah diadakan kegiatan pelatihan implementasi scratch dalam pembelajaran pemahaman kemampuan berpikir komputasional guru menjadi 88,33. Nilai rata-rata tes kemampuan berpikir komputasional guru sebelum kegiatan pelatihan adalah 23, 89 dan selanjutnya setelah mengikuti kegiatan pelatihan maka nilai rata-rata menjadi 73,06. Berdasarkan hal tersebut maka dapat dilihat ada peningkatakan kemampuan beripikir komputasional akibat diadakan kegiatan pelatihan scratch dalam pembelajaran.
