Abstract

Students need to master conic material when studying curved-sided geometric figures. However, cone material is still difficult for students to understand. Therefore, this research aims to create a learning trajectory that can make students understand the concept of cones using the context of the mitoni tradition in class IX SMP. Using the design research method, this method has three stages, namely preliminary design, design experiment (pilot experiment and teaching experiment), and retrospective analysis. This research was designed and developed using the Indonesian Realistic Mathematics Education (PMRI) approach. The research subjects consisted of 32 class IX students at SMP Negeri 39 Semarang, which was carried out from August to September 2023. The results of this research were a learning trajectory that included a series of learning processes with three activities, namely observing videos of the mitoni tradition to find the elements of cones; find the formula for the surface area of a cone; determine the formula for the volume of a cone; and solving contextual problems related to cones. This activity was carried out to increase students' understanding of cone material. The research results show that the context of the mitoni tradition can help students understand the concept of cones. Apart from that, the results of this research present alternative local wisdom that can be used in mathematics, especially in cone materials.

Pembelajaran matematika siswa akan lebih bermakna ketika materi berkaitan dengan kondisi yang sesuai dengan apa yang ada di sekitarnya. Pentingnya penelitian ini dilakukan karena Menara Kudus yang merupakan salah satu peninggalan budaya dapat dilestarikan melalui pembelajaran disekolah sebagai sumber belajar yang bermakna bagi siswa. Penelitian ini bertujuan untuk mengeksplorasi dan memperdalam etnomatematika di Menara Kudus sebagai sumber belajar bagi siswa. Dalam penelitian ini menggunakan jenis penelitian deskriptif kualitatif dengan pendekatan etnografi. Teknik pengumpulan data menggunakan observasi dan pencatatan. Teknik analisis data yang digunakan reduksi data, penyajian data dan penarikan kesimpulan. Objek pengamatan pada kegiatan ini adalah bangunan Menara Kudus. Simpulan dari penelitian ini didapatkan bahwa geometri yang terdapat pada bangunan Menara kudus adalah bagian dasar menara yang menampilkan banyak dekorasi batu bata dan dapat dimodelkaan menggunakan geometri persegi panjang, persegi, segitiiga, dan berlian. Untuk badan menara dimodelkan pelat dan batu bata menggunakan geometri lingkaran,  persegi panjang, dan berlian. Sebaliknya tangga tower dengan dinding dan pintu dapat dimodelkan sebagai trapesium, segitiga sama kaki, segitiga siku-siku, trapesium. Students' mathematics learning will be more meaningful when the material is related to conditions that are in accordance with what is around them. The importance of this research is that the Menara Kudus, which is one of the cultural heritages, can be preserved through learning at school as a meaningful learning resource for students. This research aims to explore and deepen ethnomathematics at Menara Kudus as a learning resource for students. This research uses a qualitative descriptive research type with an ethnographic approach. Data collection techniques use observation and recording. The data analysis techniques used are data reduction, data presentation and drawing conclusions. The object of observation in this activity is the Menara Kudus building. The conclusion from this research is that the geometry found in the Menara Kudus building is the base of the tower which displays many brick decorations and can be modeled using rectangular, square, triangle and diamond geometries. For the tower body, plates and bricks were modeled using circle, rectangle and diamond geometry. On the other hand, tower stairs with walls and doors can be modeled as trapezoids, isosceles triangles, right triangles, trapezoids.

Abstract

Pembelajaran abad ke-21 menekankan pentingnya mengembangkan keterampilan siswa, termasuk dalam mata pelajaran matematika. Namun, hasil belajar matematika di Indonesia masih rendah, terutama karena pendekatan pembelajaran yang kurang efektif dan beragam. Penelitian ini menerapkan Model Problem Based Learning (PBL) dengan dukungan Lembar Kerja Peserta Didik (LKPD) berbasis Kontekstual pada Materi Barisan dan Deret untuk meningkatkan hasil belajar siswa. Melalui penelitian tindakan kelas di SMK N 07 Semarang, hasil menunjukkan peningkatan signifikan dalam pencapaian siswa. Dari hanya 22,2% siswa yang mencapai ketuntasan minimal sebelumnya, peningkatan pesat terjadi setelah menerapkan PBL dengan LKPD, mencapai 86,1% pada siklus kedua. Hasil ini menunjukkan potensi besar model pembelajaran tersebut dalam meningkatkan hasil belajar siswa. Integrasi PBL dengan LKPD berbasis kontekstual disarankan dalam kurikulum untuk meningkatkan hasil belajar secara menyeluruh dengan memperhatikan pelatihan guru dan pengembangan materi yang sesuai.

Abstract

HIV/AIDS is a global health issue that significantly impacts adolescents, a vulnerable group prone to risky behaviors such as unprotected sexual intercourse. The lack of knowledge is a key factor contributing to the increased risk of transmission. Therefore, effective health education interventions are essential to address this problem, with one promising approach being health promotion through audiovisual media. This study aims to assess the impact of audiovisual media on improving HIV/AIDS knowledge among 11th-grade students at SMA PGRI 2 Banjarmasin. The study used a quasi-experimental design with a one-group pretest–posttest approach. The entire population of 112 students was selected using a total sampling technique. The data collection tool was a questionnaire that was tested for validity and reliability. The data were analyzed using the Wilcoxon test, as the data were not normally distributed. Prior to the intervention, most students (85.7%) had low levels of knowledge about HIV/AIDS. Following the intervention, all students (100%) demonstrated a significant increase in knowledge, reaching a high level. The Wilcoxon test yielded a p-value of 0.001 (p<0.05), indicating a statistically significant effect. These findings suggest that audiovisual media is a highly effective method for improving adolescents’ knowledge about HIV/AIDS. It serves as both an engaging and preventive educational strategy, making it an important tool in promoting awareness and reducing the risk of HIV/AIDS transmission among youth.

Abstract

This study aims to improve student learning outcomes and engagement through the implementation of the Teaching at the Right Level (TaRL) approach combined with the Problem Based Learning (PBL) model. The TaRL approach focuses on teaching that is appropriate to each student's ability level, while PBL encourages students to actively solve relevant problems, so that it is expected to improve student engagement and learning outcomes. This study was conducted in the form of classroom action research (CAR) consisting of two cycles. Each cycle includes the planning, implementation, observation, and reflection stages. In the first cycle, the results of student learning completion reached 64%. After reflection and improvement in the first cycle, it was continued with the second cycle which showed an increase in student learning completion to 78%. There was a difference in increase of 14% between the first and second cycles. The results of this study indicate that the implementation of the TaRL approach combined with the PBL model can effectively improve student learning outcomes and engagement. The increase in learning completion from the first cycle to the second cycle illustrates that this approach and model are able to accommodate differences in student abilities and facilitate more effective and interesting learning. Thus, the TaRL approach and the PBL model can be used as effective learning strategies to improve the quality of education in the classroom.
