Abstract

Dilation is a part of geometry transformation that is useful for students. However, students often have difficulty in understanding dilation material. Therefore, this study aims to develop a learning trajectory to facilitate students in understanding dilation material by using the context of Tedhak Siten tradition. The research subjects consisted of 32 ninth grade students of SMP Negeri 6 Semarang, which was conducted from August to September 2023. The research method used is design research which consists of three stages, namely preparing for experiment, design experiment, and retrospective analysis. All learning activities were based on the Realistic Mathematics Education approach and supported by GeoGebra media. The results of this study include three learning activities, including: observing the Tedhak Siten tradition video to find the properties and definition of dilation, finding the formula and results of dilation, and solving contextual problems related to dilation. From the activities carried out, it can be seen that learning dilation by using the context of the Tedhak Siten tradition based on RME and supported by GeoGebra media can help students improve their understanding of the concept of dilation material in class IX SMP Negeri 6 Semarang. In addition, Tedhak Siten tradition can be used as a relevant context in learning mathematics.

Abstract

Statistics is a staple in the curriculum because it is considered necessary in everyday life. However, students often find statistics challenging. Students' difficulties in learning statistics are caused by several factors, including a lack of understanding of mathematical concepts and principles in solving problems. This study aimed to design and develop a Hypothetical Learning Trajectory (HLT) for grade VIII statistics using the Realistic Mathematics Education (RME) approach, with Pranata Mangsa as the learning context. The method used in this research was validation-type design research. This research produced an HLT of statistics material using pranata mangsa context consisting of 3 activities to help students understand and master the material. The activities of the HLT are 1) collecting, presenting, and analyzing data, 2) measuring centralized data, and 3) measuring data distribution. The results showed an HLT for teaching statistics using RME that can effectively support students of all ability levels. This HLT allows students to rediscover statistics concepts through horizontal and vertical mathematical processes. Finally, the HLT facilitates students to create their models from informal to formal and increases the interaction between students and teachers. Statistika menjadi materi pokok dalam kurikulum karena dianggap penting dalam kehidupan sehari-hari. Namun, pada kenyataannya statistika merupakan salah satu pelajaran yang dianggap sulit bagi siswa. Kesulitan siswa dalam belajar statistika disebabkan oleh beberapa faktor, diantaranya kurangnya pemahaman konsep dan prinsip-prinsip matematika dalam menyelesaikan soal. Tujuan penelitian untuk mendesain dan mengembangkan Hypothetical Learning Trajectory (HLT) menggunakan pendekatan Realistic Mathematics Education (RME) pada materi statistika kelas VIII menggunakan konteks Pranata Mangsa yang menjadi starting point dalam pembelajaran. Metode yang digunakan dalam penelitian ini adalah design research tipe validasi. Penelitian ini menghasilkan HLT materi statistika menggunakan konteks pranata mangsa yang terdiri dari 3 iceberg untuk membantu siswa dalam memahami dan menguasai materi. Adapun iceberg dari HLT tersebut adalah 1) mengumpulkan, menyajikan, dan menganalisi data; 2) ukuran pemusatan data; dan 3) ukuran penyebaran data. Hasil penelitian ini menunjukkan bahwa HLT mampu membantu siswa menemukan kembali konsep statistika melalui proses matematika horizontal dan vertikal. HLT memfasilitasi siswa untuk membuat model mereka sendiri dari informal ke formal dan meningkatkan interaksi antara siswa dan guru.

Abstract

Reflection material is very important for students to master when studying transformation material. However, reflection material is still difficult for students to understand. Therefore, this research aims to create a learning trajectory that can help students understand the concept of reflection using the context of the Tedhak Siten tradition with the help of GeoGebra software in grade 9th of SMP Negeri 6 Semarang. This research uses a design research method consisting of three stages: preliminary design, design experiment, and retrospective analysis. In this research, a series of learning activities were designed and developed based on the (Realistic Mathematics Education) RME approach. This research involved 6 grade 9th students. The result of this research is a learning trajectory that includes a series of learning processes in three activities, namely: 1) Observing the Tedhak Siten tradition video to find the definition and characteristics of reflection; 2) Finding formulas and reflection results; and 3) Resolving contextual problems related to reflection. The conducted activity can aid in improving students’ comprehension of reflection material. The research results showed that students could discover the characteristics and definitions of reflection, find formulas and reflection results, and solve contextual problems related to reflection.

Abstract

Pelatihan pembuatan saputangan bermotif batik bertujuan untuk meningkatkan keterampilan teknik batik peserta serta mendorong kreativitas dalam desain produk rumah tangga. Program pengabdian ini melibatkan penyampaian teori dan praktik langsung. Hasil pelatihan menunjukkan bahwa peserta berhasil menerapkan teknik batik dengan baik, menghasilkan produk akhir yang berkualitas. Peserta juga menunjukkan tingginya tingkat kreativitas dalam menciptakan motif batik. Tanggapan balikan pihak penyelenggara pelatihan adalah kepuasan atas materi pembicaraan dan arahan seperti juga rencana di masa depan pencapaian dari langkah-langkah tersebut untuk memperoleh penghidupan kerajinan tangan. Pelatihan ini memberikan dampak positif pada aspek ekonomi dan sosial, dengan potensi untuk pemberdayaan ekonomi lokal dan pelestarian budaya batik. Hendaknya program pelatihan diperluas ke komunitas lain agar hasil lebih maksimal lagi di mana itu menjadi hal penting atau materi dikembangkan lebih lanjut guna hasil lebih optimal.
