PENGEMBANGAN VIDEO PEMBELAJARAN BERBASIS ETNOMATEMATIKA PADA MATERI BANGUN DATAR KELAS VII SMP NEGERI 3 TANJUNG BINTANG
This study aims to develop an ethnomathematics-based instructional video on plane geometry, as students’ lack of interest in learning mathematics, particularly in this topic, has led to low learning outcomes. The development model applied was ADDIE, consisting of five stages: Analysis, Design, Development, Implementation, and Evaluation. The research subjects were seventh-grade students at SMP Negeri 3 Tanjung Bintang. The research instruments included validation sheets, student response questionnaires, teacher responses, and learning achievement tests. The media validation results obtained a percentage of 92% (Very Valid), material validation 88% (Valid), and language validation 90% (Very Valid). Product trials indicated that student responses to the ethnomathematics-based instructional video reached 87% (Attractive). Student achievement tests showed classical mastery of 88% (High), while teacher responses to the media were categorized as Very Practical. Thus, the ethnomathematics-based instructional video on plane geometry developed through the ADDIE model is declared highly valid, practical, and effective. This media can attract students’ interest, receive positive feedback from teachers, and improve student learning outcomes.

PENGARUH MODEL PROBLEM BASED LEARNING BERBASIS ARTIFICIAL INTELEGENCE (AI) TERHADAP KEMAMPUAN PEMECAHAN MASALAH MATEMATIS SISWA KELAS VIII SMP N 17 PESAWARAN TAHUN PELAJARAN 2025/2026
This study aims to determine the effect of artificial intelligence (AI) based problem-based learning model on the mathematical problem-solving ability of eighth-grade junior high school students in the 2025/2026 academic year. This study is an experimental study with the research population being all eighth-grade students in the odd semester of SMP Negeri 17 Pesawaran. Class VIII D is the experimental class and class VIII E is the control class. The sampling technique used is Cluster Random Sampling. Measurement of students' mathematical problem-solving ability uses an essay-shaped test of 5 questions. Data analysis uses a prerequisite analysis test with the acquisition of t_hit = 4.16 and for a significance level of 5% (α = 0.05) obtained t_daf = 1.67. Thus t_hit>t_daf then there is not enough reason to accept H_0, meaning H_a is accepted. Thus, it can be concluded that the use of an artificial intelligence (AI)-based problem-based learning model has an impact on the mathematical problem-solving abilities of eighth-grade junior high school students in the 2025/2026 academic year.
EFEKTIVITAS PENGGUNAAN LKPD BERBASIS HOTS TERHADAP KEMAMPUAN PEMECAHAN MASALAH MATEMATIKA PESERTA DIDIK KELAS VIII SMP NEGERI 6 TULANG BAWANG BARAT TAHUN PELAJARAN 2024/2025
The study aims to determine and analyze the effectiveness of using HOTS-Based LKPD on the Mathematical Problem Solving Ability of Class VIII Students of SMP NEGERI 6 Tulang Bawang Barat in the 2024/2025 Academic Year. This study uses an experimental method. The population in this study were all students of class VIII in the even semester of SMP NEGERI 6 Tulang Bawang consisting of 8 classes with a total of 250 students, while the sample was taken from 2 classes, namely class VIII 2 as the experimental class, and class VIII 6 as the control class. After the normal and homogeneous data were obtained, the results of the hypothesis testing using the t-test obtained a value of t = 3.94. From the t distribution table at a significance level of 5%, it is known that t = t(1-α) = 1.67 t > t so it can be concluded that "The Use of HOTS-Based LKPD is Effective on the Mathematical Problem Solving Ability of Class VIII Students of SMP Negeri 6 Tulang Bawang Barat in the 2024/2025 Academic Year".

PENGEMBANGAN LEMBAR KERJA PESERTA DIDIK (LKPD) BERBASIS ETNOMATEMATIKA MENGGUNAKAN PERMAINAN TRADISIONAL LAMPUNG TAPLAK PADA MATERI SEGI EMPAT SEGITIGA KELAS VII SMP SWADHIPA 1 NATAR
This research and development is based on the fact that mathematics teaching materials for class VII SMP Swadhipa 1 Natar do not meet the learning needs of students' mathematics and do not bridge mathematics and culture. The teaching materials used are limited to student handbooks. The objectives of this research and development are: 1) to develop and determine the feasibility of ethnomathematics-based worksheets using traditional Lampung tablecloth games on the subject matter of rectangles and triangles in terms of their validity as teaching materials, 2) to find out the response of teachers and students to the developed ethnomathematics-based worksheets, and 3) find out the effectiveness of the Student Worksheets (LKPD) developed in terms of student learning outcomes on the subject of rectangles and triangles. This study uses research and development (R&D) methods with the Analysis, Design, Development, Implementation, and Evaluation (ADDIE) development model. The results showed that material validation for Student Worksheets (LKPD) with a value of 4.25, media validation with a value of 4.13, and language validation with a value of 4.76, all of which were declared valid. Student responses showed an average of 4.58 in the interesting category, while teacher responses showed an average value of 4.61 in the practical category as teaching materials. After using the developed ethnomathematics-based Student Worksheets (LKPD), the percentage of students' learning completeness reached 90% which indicated that the developed LKPD was effective on students' mathematics learning outcomes in rectangular and triangular material. These results indicate that ethnomathematics-based Student Worksheets (LKPD) for class VII SMP are appropriate for use as teaching materials.
