AbstrakTujuan penelitian ini adalah untuk mendeskripsikan keefektifan pembelajaran matematika dengan model search, solve, create, and share (SSCS) dan apakah pembelajaran matematika dengan model SSCS lebih baik dibandingkan dengan model konvensional ditinjau dari prestasi, penalaran matematis, dan motivasi belajar. Penelitian ini merupakan penelitian eksperimen semu dengan desain kontrol grup nonekuivalen. Populasi dalam penelitian adalah seluruh siswa kelas VIII SMP Muhammadiyah Banguntapan yang terdiri dari lima kelas. Sampel penelitian diambil dua kelas secara acak, yaitu kelas VIII-D dan VIII-E. Analisis data yang digunakan adalah uji T 2 Hotelling's, uji MANCOVA, dan uji lanjut dengan prosedur t-test. Setiap analisis dilakukan pada taraf signifikansi 5%. Hasil penelitian ini adalah pembelajaran matematika dengan model SSCS efektif ditinjau dari prestasi dan motivasi belajar, tetapi tidak efektif ditinjau dari penalaran matematis siswa dan pembelajaran matematika dengan model SSCS lebih baik dibandingkan dengan pembelajaran konvesional ditinjau dari prestasi dan penalaran matematis, tetapi tidak lebih baik ditinjau dari motivasi belajar siswa kelas VIII SMP Muhammadiyah Banguntapan. Kata Kunci: model SSCS, model konvensional, prestasi belajar, penalaran matematis, motivasi belajar siswa
This cultural diversity can be utilized in exploring mathematical concepts bridged by ethnomathematics to bring mathematics closer to students' cultures. However, on the other hand, many people think that mathematics is culture-free. The uniqueness and diversity of cultures in ideas, activities, and artifacts can be studied and used as learning resources, especially in mathematics. Therefore, this study seeks to explore the geometrical perceptions and cultural values contained in the traditional woven fabric motifs of the Sasak people. This research is qualitative research with an ethnographic method. Research data were collected through observation, literature study, and interviews with cultural practitioners, traditional leaders, woven fabric craftsmen, and cultural. The results of this study indicate that the traditional woven fabrics of the Sasak people have recognized and used mathematical concepts, especially lines, angles, flat shapes, and geometric transformations, in the design of traditional woven fabric motifs of the Sasak people. In addition, there is a philosophical meaning contained in each motif or pattern. The meaning is in the form of cultural values such as moral, historical, and philosophical values, which are used as messages to their children and grandchildren.
Salah satu upaya untuk minimalisasi tingkat plagiat di kalangan mahasiswa dalam menyusun tugas akhir adalah optimalisasi studi literatur dan melakukan pengecekan tingkat plagiat menggunakan aplikasi standar seperti Plagiarism CheckerX. Tujuan kegiatan ini adalah meningkatkan kemampuan mahasiswa dalam menyusun tugas akhir dengan tingkat plagiasi tidak lebih dari 30%. Oleh sebab itu, sebanyak 83 mahasiswa telah mengikuti kegiatan workshop penggunaan software Plagiarism CheckerX serta dijelaskan teknik memperbaiki hasil plagiat jika lebih dari 30%. Angket merupakan alat evaluasi yang digunakan dalam kegiatan ini. Hasil pelaksanaan kegiatan menunjukkan bahwa sebesar 89% mahasiswa memahami materi yang disampaikan dan memahami teknik mengecek plagiat serta memperbaiki hasil plagiat tersebut.
The aim of study is to forecast global tourist visits and compare the forecasting methods to determine the best method using random forest, single exponential smoothing and double exponential smoothing, respectively. These methods are applied in global tourist visit data in West Nusa Tenggara Province. Random forest, single exponential smoothing and double exponential smoothing are familiar methods and are frequently utilized in forecasting. In addition, the three methods have great accuracy for time series data, such as data of global tourist visits. The data used in this study is data of global tourist visits from 2014 to 2021 in West Nusa Tenggara province. Applying the random forest, single exponential smoothing and double exponential smoothing methods in forecasting, the result shows that double exponential smoothing method is the best, based on the smallest value of Mean Absolute Percentage Error (MAPE) of 325.759. The forecasting result found out that tourist visits will increase from previous time, starting from August, 2021 to July, 2021 with an estimated 847 to 1045 lives
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
