Abstract

Perlu adanya penelitian yang dapat mendeskripsikan kemampuan representasi matematis siswa ditinjau dari gaya belajar mereka. Penelitian ini menggunakan pendekatan kualitatif deskriptif. Subjek dari penelitian ini adalah 20 siswa kelas VII-D SMPN 4 Jember. Pengambilan sampel subjek dengan menggunakan teknik purposive sampling. Teknik pengumpulan data melalui angket gaya belajar, tes kemampuan representasi matematis dan wawancara. Analisis data dilakukan dalam tiga langkah yaitu reduksi data, penyajian data, dan penarikan kesimpulan. Siswa yang memiliki gaya belajar visual dominan pada kemampuan representasi visual, dan siswa yang memiliki gaya belajar auditori dominan pada kemampuan representasi verbal. Sedangkan pada siswa yang memiliki gaya belajar kinestetik terlihat dominan pada kemampuan simbolik. Sehingga pembelajaran matematika yang memperhatikan gaya belajar siswa diperlukan, agar dapat mempermudah guru untuk memberikan stimulus yang tepat pada setiap kelompok sehingga memperoleh respon positif dari siswa dalam merepresentasikan ide-ide matematikanya. There is a need for research that can describe students' mathematical representation abilities in terms of their learning styles. This study uses a descriptive qualitative approach. The subjects of this study were 20 students of class VII-D SMPN 4 Jember. The subject sampling was by using purposive sampling technique. Data collection techniques through learning style questionnaires, mathematical representation ability tests and interviews. There were 3 steps of data analysis, namely data reduction, data presentation, and drawing conclusions. Students who have a visual learning style are dominant in visual representation abilities, and students who have an auditory learning style are dominant in verbal representation abilities. Meanwhile, students who have a kinesthetic learning style are dominant in symbolic abilities. So that learning mathematics that pays attention to student learning styles is needed, in order to make it easier for teachers to provide the right stimulus to each group so as to get a positive response from students in representing their mathematical ideas.

Abstract

Abstrak Tujuan dari penelitian ini adalah untuk menganalisis proses berpikir siswa tunagrahita ringan dalam menyelesaikan masalah kontekstual persegi dan persegi panjang berdasarkan pemecahan masalah IDEAL. Jenis penelitian ini adalah penelitian deskriptif dengan pendekatan kualitatif. Subjek penelitian adalah 2 siswa tunagrahita ringan di SLB-C TPA Negeri 1 Branjangan. Metode pengumpulan data yang digunakan adalah tes dan wawancara. Instrumen penelitian ini yaitu peneliti, soal tes, dan pedoman wawancara. Proses berpikir kedua subjek cenderung mengalami proses disequilibrium, asimilasi, akomodasi dan equilibrium pada lima tahap IDEAL. Subjek mengalami disequilibrium ketika subjek tidak dapat memahami maksud dari soal karena belum pernah menjumpai masalah kontekstual sebelumnya, mengalami asimilasi ketika subjek menjawab pertanyaan dari peneliti secara spontan, mengalami akomodasi ketika subjek dapat menjawab pertanyaan dengan benar yang awalnya salah, dan mengalami equilibrium ketika subjek mampu memahami serta menjawab pertanyaan-pertanyaan dengan benar. Hasil penelitian ini berimplikasi bagi dunia Pendidikan khususnya sekolah yang memiliki siswa tunagrahita ringan dalam mendesain pembelajaran yang dapat memfasilitasi pemecahan masalah. Abstract The purpose of this research was to analyze the thought process of mildly retarded students in solving square and rectangular contextual problems based on IDEAL problem solving. This type of research was descriptive research with a qualitative approach. The subjects were 2 mildly retarded students at SLB-C TPA Negeri 1 Branjangan. The data collection methods used were tests and interviews. The instruments of this research were researchers, test questions, and interview guidelines. The thinking process of the two subjects tends to experience the process of disequilibrium, assimilation, accommodation and equilibrium at the five stages of IDEAL. The subject experienced disequilibrium when the subject could not understand the meaning of the problem because he had never encountered contextual problems before, experienced assimilation when the subject answered questions from the researcher spontaneously, experienced accommodation when the subject could answer questions correctly which were initially wrong, and experienced equilibrium when the subject was able to understand and answer the questions. The results of this study have implications for the world of education, especially schools with mildly retarded students in designing learning that can facilitate problem solving.

Abstract

Numeracy is a person's ability to implement mathematics in the home, work and community environments. This research aims to measure the practicality and effectiveness of using E-LKPD in a socio-cultural context assisted by GeoGebra workbooks in improving students' numeracy skills in pyramid material. The type of research used was a quasi-experiment (Quasi-experiment) with research subjects 21 class VIII students at SMPN 1 Kalisat Jember. The practicality of E-LKPD is assessed from the results of student response questionnaires, while the effectiveness of E-LKPD is assessed from the results of students' numeracy ability tests. The use of E-LKPD is said to be practical if the average percentage of students' questionnaire responses is at least in the practical category, and effective if students' numeracy skills are at least in the medium category. Based on the practicality analysis, the results of the student response questionnaire regarding the use of E-LKPD obtained a percentage of 81.67% or were in the practical category. In addition, the use of E-LKPD shows an increase in students' numeracy skills on all numeracy indicators. This can be seen based on the results of the numeracy ability test which obtained an N-Gain score of 0.51 or at a medium effectiveness level. Therefore, the use of E-LKPD in a socio-cultural context with the help of GeoGebra workbooks is practical and effective for improving students' numeracy skills, especially in learning surface area and volume of pyramids.

Abstract

This research aims to develop an Electronic Student Worksheet (E-LKPD) using the Wizer.Me platform for teaching polyhedron material that meets the criteria of validity, practicality, and effectiveness. The study employed a Research and Development (R&D) approach with the ADDIE model. The E-LKPD was designed based on a guided discovery learning model to help students better understand polyhedron concepts, their interconnections, and applications. Learning activities include matching polyhedron shapes with their names and discovering formulas through the “fill on image” feature in exploration tasks. The research was conducted at SMPN 1 Ledokombo, Jember, involving eighth-grade students as participants. Validation results show that the E-LKPD achieved a validity score (Va) of 3.84, indicating a valid category. The practicality level reached 82%, as evidenced by student response questionnaires, reflecting positive usability and engagement. Furthermore, the E-LKPD demonstrated effectiveness, with 34 out of 43 students achieving classical mastery, meaning more than 75% met the minimum learning standard. These findings indicate that the developed E-LKPD using Wizer.Me effectively supports students’ conceptual understanding and learning outcomes in polyhedron material, providing a valid, practical, and efficient digital learning tool for mathematics education.

Abstract

Aluminium Silikon merupakan material paduan yang kebermanfaatannya dapat digunakan diberbagai aplikasi otomotif dan industri dirgantara. Dengan potensi kemampuan yang luar biasa seperti castability, ketahanan abrasi dan korosi yang sangat tinggi, serta kekuatan yang sangat baik, maka membuat material ini untuk terus dilakukan rekayasa penelitian. Salah satau upaya meningkatkan mechanical properties pada aluminium silikon adalah dengan menambahkan penguat. Titanium dioksida (TiO2) merupakan salah satu jenis penguat yang mampu meningkatkan nilai kekuatan mekanik. Penelitian ini bertujuan untuk mendapatkan komposisi yang optimal Titanium dioksida (TiO2) sebagai penguat tambahan pada aluminium silikon. Adapun variasi penambahan penguat yang dilakukan adalah 0,2, dan 4%. Metode yang digunakan adalah stir casting. Hasil yang didapatkan adalah semakin tinggi penambahan partikel penguat akan berbanding lurus dengan jumlah porositas. Hal ini juga didukung dengan hasil pengamatan struktur mikro bahwa bertambahnya partikel penguat berupa Titanium dioksida (TiO2) pada aluminium silikon, maka partikel penguat tersebut mengalami nukleasi. Dengan demikian berdampak pada aliran logam cair yang dapat menimbulkan porositas.

Abstract

The concept of mathematical material is still not fully embedded in students' schemes, this means that errors occur in constructing the concept. This research aims to describe the actual situation regarding pseudo-construction errors that occur at the APOS (Action, Process, Object, and Scheme) stages. This research involved 28 students in class VIII A of SMPN 2 Silo Jember as subjects through problem solving test to get an comprehensive information about occuring errors. Then by the purposive sampling and snowball sampling techniques, two subjects are choosen to explore in depth through interview. The data valiadation is guarantee through the member check process. Data analysis includie data condensation, data presentation, and concluding. The results of the research are that pseudo-construction errors occur at every stage of APOS which results in the concept not being fully constructed in the student's scheme. As a recommendation, developing a mathematics learning model based on APOS theory to minimize the error is needed such that the concepts will be well and completely constructed in students' schemes. Konsep materi matematika masih belum sepenuhnya tertanam dalam skema siswa. Hal ini menunjukkan bahwa terjadi kesalahan dalam mengkonstruk konsep. Penelitian ini bertujuan untuk menggambarkan atau mendeskripsikan keadaan yang sebenarnya terkait kesalahan konstruksi semu yang terjadi pada tahapan APOS (Aksi, Proses, Objek, dan Skema). Penelitian ini melibatkan 28 siswa kelas VIII A SMPN 2 Silo Jember sebagai subjek melalui tes pemecahan masalah untuk mendapatkan informasi komprehensif tentang kesalahan yang terjadi. Kemudian dengan teknik purposive sampling dan snowball sampling, dipilih dua subjek untuk dieksplorasi secara mendalam melalui wawancara. Validasi data dijamin melalui proses member check. Analisis data meliputi kondensasi data, penyajian data, dan penarikan kesimpulan. Hasil penelitian yaitu kesalahan konstruksi semu terjadi disetiap tahapan APOS yang mengakibatkan konsep tidak terkonstruk dengan utuh dalam skema siswa. Sebagai rekomendasi, perlu dikembangkan model pembelajaran matematika berbasis teori APOS untuk meminimalkan kesalahan agar konsep-konsep dapat terkonstruksi dengan baik dan lengkap dalam skema siswa.

Abstract

One of the cultural behaviors of local wisdom that is starting to disappear is related to how manage the "garbage". Several communities still throw garbage out of place, such as in the river. On the other hand, the effects of this waste that was disposed of carelessly are very long-term for human health and also the environment. This culture is eventually emulated by their children and grandchildren who are still in school. For this reason, community awareness regarding waste needs to be directed, one of which is the management of a community waste bank. In Tegalsari Village, Ambulu Jember there is one Cipta Mandiri Waste Bank that has been operating for the last 3 years. The Waste Bank activity went quite well, but less than 20% of the community participated, especially young people and children who were less interested. So that the empowerment of the Waste Bank needs to be supported in order to be able to pass down the local culture of being aware of waste, especially for elementary school students through the socialization and education of ethnomathematics worksheets in the elementary school. The results of the activity showed that 78% of students wanted to take part in the waste bank around their homes and they enjoy learning with ethnomathematics worksheets about garbage.
