Abstract

The wedding process in Sidareja village, Sidareja District, Cilacap Regency is carried out using a unique and rich traditional ceremony with a meaning that is still thick with Javanese customs. However, this culture is still not widely used to strengthen learning, especially in mathematics learning, so by using ethnomathematical studies, it is hoped that it can clarify the study of the traditional culture of marriage in Sidareja village to be used in learning at school. The purpose of this study is to explore mathematical objects contained in wedding customs in Sidareja Village, Cilacap Regency, Central Java Province. The method used in this study is a descriptive qualitative method. The data collection technique in this study uses documentation, interviews, and observations. This research was carried out by exploring the sources of activities around traditional wedding ceremonies in Sidareja starting from: Preparation, Premarital Ceremony to Panggih Ceremony. The mathematical aspects that are explored include how Preparation (determining the wedding day) is included in the measurement material starting from counting in the concept of division, addition, and numbering. In addition, it was also presented a study of learning about flat figures, namely with the form of flat shapes such as rectangles, parallelograms, triangles, in terms of many, and rhombus found in majang tarub, sindur cloth, chitak, paes, keris-kerisan, kuluk, and suweng which are used in traditional wedding ceremonies in Sidareja village, Cilacap Regency, Central Java Province

Abstract

Effective mathematical communication plays a crucial role in the resolution of mathematical problems. Despite efforts to enhance mathematical communication, the success rate among students remains relatively low, a situation that is closely associated with their levels of self-efficacy. The purpose of the study was to describe students' mathematical communication skills based on self-efficacy. The research adopts a descriptive qualitative method. The subjects of this study consisted of seventh-grade students who had studied the material on flat shapes. According to the outcomes of the self-efficacy questionnaire, students are classified into three categories: high, medium, and low. Each category was taken by one student as a respondent with the purposive sampling technique. Data collection techniques include tests, questionnaires, and interviews. Data analysis techniques include data reduction, data presentation, and conclusion. The analysis indicated that students exhibiting higher levels of self-efficacy displayed enhanced mathematical communication skills when compared to their peers who possessed lower levels of self-efficacy. This study revealed a significant relationship between mathematical communication and self-efficacy. Students with elevated levels of self-efficacy display enhanced proficiency in mathematical communication skills in comparison to their peers who possess medium and low levels of self-efficacy.

Abstract

A crucial aspect in various disciplines is numeracy skills. The purpose of the study was to determine the difference in the average social-emotional competence and numeracy skills of students before and after the implementation of differentiated learning that integrated social-emotional competence. The research was conducted at SMP Negeri Satu Atap 1 Cimanggu, Cilacap. The sample in this study was selected using the saturated slicing technique involving 22 grade VIII students. The type of research is an experimental study that uses a pre-experimental design with a one-group pre-test post-test method. The data collection techniques used include observation, tests, and questionnaires. There are 20 questions in the questionnaire. Data analysis was carried out quantitatively using paired sample t-tests and descriptive statistics. Before conducting the analysis, a prerequisite test was carried out using a normality test to test the distribution of data. The results of the study showed that the numeracy skills had a significance value of 0.200 (>0.05) and the social-emotional competence had a significance value of 0.11 (>0.05) which showed that the data was normally distributed. The results of the analysis showed that the value of the t-test of numeracy was 49.423 (t-test > ttable), with a significance value (2-tailed) < 0.05 (0.00 < 0.05). For KSE, the statistical value of the t-test was 27.54 with a very small p-value (5.75×10⁻¹⁸) indicating that there is a significant difference in the average value of numeracy skills and KSE before and after the implementation of integrated differentiation learning KSE. Integrated differentiation learning KSE can be applied to improve numeracy skills. The results of this study can be used as a solution to overcome the low mathematical numeracy skills of students.

Abstract

Pembelajaran matematika sering dianggap sulit dan abstrak oleh peserta didik, sehingga diperlukan media yang mampu meningkatkan pengalaman belajar yang bermakna dan menarik. Penelitian ini bertujuan mengembangkan media e-komik berbasis etnomatematika guna meningkatkan kemampuan berpikir divergen dan self-efficacy siswa pada materi geometri kelas IV. Pendekatan yang digunakan adalah kuantitatif dengan metode preeksperimen melalui desain pretest-posttest satu kelompok eksperimen. Media e-komik diharapkan mampu meminimalisir kekurangan media cetak dan mengaitkan konsep matematika dengan kebudayaan lokal untuk memberikan konteks yang relevan. Hasil penelitian menunjukkan bahwa penggunaan media ini berkontribusi signifikan terhadap peningkatan pemahaman konsep, kemampuan berpikir kreatif, serta kepercayaan diri siswa dalam belajar matematika. Dengan demikian, media e-komik berbasis etnomatematika dapat menjadi alternatif inovatif dalam meningkatkan hasil belajar matematika peserta didik.

Abstract

Penelitian ini bertujuan untuk mengidentifikasi strategi optimal dalam memanfaatkan teknologi digital guna meningkatkan mutu pembelajaran di SMP Negeri Satu Atap 1 Cimanggu. Penelitian dilaksanakan dengan menggunakan metode deskriptif kualitatif yang melibatkan kepala sekolah, wakil kepala sekolah, guru, siswa, komite sekolah, dan orang tua sebagai informan utama. Data dikumpulkan melalui observasi, wawancara, dan dokumentasi sebagai bentuk implementasi metode pengumpulan data yang komprehensif. Data yang diperoleh dianalisis menggunakan model analisis interaktif yang meliputi reduksi data, penyajian data, dan penarikan kesimpulan. Validitas temuan diperkuat melalui triangulasi teknik  dan triangulasi sumber. Hasil penelitian menunjukkan bahwa pemanfaatan teknologi digital memberikan dampak positif terhadap efektivitas pembelajaran, peningkatan keterlibatan siswa, serta efisiensi manajemen data sekolah. Namun, tantangan seperti keterbatasan infrastruktur dan rendahnya literasi digital masih perlu mendapatkan perhatian. Secara keseluruhan, penelitian ini menegaskan pentingnya kepemimpinan, kolaborasi, dan penguatan kompetensi digital sebagai faktor kunci dalam keberhasilan program digitalisasi pendidikan.
