Abstract

Education in Indonesia currently still uses textbooks as teaching materials. On the other hand, students are required to have the ability to think critically, collaborate, communicate, and be creative. However, the textbooks used in schools today still have weaknesses, mainly mathematics textbooks. One of the weaknesses found is that there are only a small number of practice questions in the mathematics textbook, which can be grouped into HOTS questions. Based on this, this research was conducted to describe the distribution of HOTS-type questions in the 2017 revised edition of the Vocational High School (SMK) mathematics textbook for class X semester one published by the Ministry of Education and Culture of the Republic of Indonesia in the material Three-Variable Linear Equation System. The research was reviewed based on the definition of HOTS questions according to Brookhart (2014), namely analyzing, evaluating, creating, reasoning and logic, making decisions, solving problems, and thinking creatively. The approach used is a descriptive quantitative approach with the researcher's agreement technique using a formula. There are 20 questions used in this study. The results of this study are that 20 questions are said to include HOTS questions with the fulfillment of HOTS question indicators, according to Brookhart, and the results of the agreement of the two analysts.

Abstract

ABSTRAK Berdasarkan analisis situasi yang dilakukan dengan metode wawancara kepada kepala SDN Dermo 2 Kediri bahwa guru belum sepenuhnya memanfaatkan dan membuat media pembelajaran digital sebagai bahan ajar alternatif. Dalam proses pembelajaran kondisi siswa banyak yang tidak menyimak penjelasan guru, hal ini bisa dilihat dari kurangnya motivasi siswa dalam menjawab setiap pertanyaan guru. Jika hal ini terus dibiarkan maka akan berdampak pada hasil belajar siswa yang tidak maksimal. Adapun solusi yang ditawarkan adalah memberi workshop, mediasi serta bantuan berupa penyediaan forum bagi guru untuk mengenal lebih jauh tentang pembuatan media pembelajaran (berbasis literasi numerasi dan TPACK) dalam pembelajaran untuk meningkatkan kompetensi guru. Metode yang digunakan pertama melakukan analisis situasi, pelaksanaan kegiatan dan evaluasi. Dari hasil evaluasi menunjukkan bahwa respon pelatihan pembuatan media pembelajaran berbasis literasi numerasi dan TPACK pada kategori keterbaruan rata-rata 88,75 dengan kategori respon sangat baik. Respon pelatihan media pembelajaran berbasis literasi numerasi dan TPACK pada kategori kebermanfaatan mencapai 91,25 dengan kategori respom sangat baik juga. Hasil kegiatan pelatihan ini secara garis besar menunjukkan keberhasilan kegiatan melalui tingkat pemahaman peserta dalam pengetahuan, keterampilan dan lebih percaya diri untuk meningkatkan kompetensi guru.

Abstract

Penelitian ini membahas perilaku debit di sepanjang kanal secara numerik menggunakan data debit yang tercatat di bagian hulu. Secara matematis perilaku debit di kanal dapat dilukiskan menggunakan persamaan Saint-Venant satu dimensi. Persamaan Saint-Venant merupakan sistem persamaan diferensial parsial non-linier dan secara umum belum ditemukan solusi analitiknya. Dalam penelitian ini model matematika tersebut disederhanakan dengan cara memodifikasi persamaan momentumnya. Persamaan Saint-Venant yang telah disederhanakan diselesaikan secara numerik menggunakan metode beda hingga eksplisit. Untuk memastikan bahwa model numerik yang dihasilkan dapat diimplementasikan, maka dilakukan uji validasi dengan model numerik yang dipilih dari literatur. Hasil simulasi menunjukkan bahwa input hidrograf dengan debit puncak 12 m3/detik mengalami peredaman debit sepanjang kanal. Pada lokasi x = 600 m dari hulu kanal, debit puncak menyusut menjadi 7,38 m3/detik.

Abstract

The ability of Indonesian students to solve mathematical problems remains moderately low, according to PISA 2022 results. Even the desire and interest to learn mathematics are still relatively low. Hence, this study will determine the impact of the Learning Cycle 7E acquiring model on problem-solving abilities in relation to understudies' mathematical disposition. The procedure used in this assessment is quantitative. A quasi-experimental design was used for this study. The order picked in this experiment is the One Group Pretest-Posttest. The testing design in this review was a cluster random sampling method and got 31 students of 10th class SMAN 3 Kota Kediri. The data assortment process utilized a mathematical disposition survey and a trial of problem-solving abilities. In testing the hypothesis, the Wilcoxon Test result is 0.000 < 0.05 which shows that the Learning Cycle 7E learning model has an effect on students' mathematical problem-solving ability, and the Kruskal-Wallis Test result is 0.972 > 0.05 which shows that there is no difference in mathematical problem-solving ability between students with high, medium, and low mathematical disposition. So, the result of this study is that the 7E Learning Cycle learning model altogether influences problem-solving abilities and is powerful for all understudies' mathematical disposition levels.

Abstract

This research goal to compare the flow properties in the rectangular and trapezoidal open channels by examining the influence of the channel side slope is depicted by simplified Saint Venant Equations. The solution of these equations has been completed numerically by using Preissmann four-point scheme. The model is simulated using the Matlab application to point out the flow properties. The proposed model is validated by the model without simplification which was selected from the literature. The validation outcomes indicate that in common, the simulation outcomes of the two models have a good agreement. The simulation results show that the greater the slope of the channel side, the greater the peak discharge and the greater the time shift. The analysis emphasizes how channel geometry influences flow behavior, indicating that trapezoidal channels, with inclined side slopes z, yield slightly higher peak discharges compared to rectangular ones. For z = 0, discharge of peak Q = 7.38 m3/s and t = 18 s. For z = 2, discharge of peak Q = 7.39 m3/s and t = 21 s. For z = 4, discharge of peak Q = 7.45 m3/s and t = 23 s. For z = 6, discharge of peak Q = 7.51 m3/s and t = 24 s.
