This research is descriptive research that aims to describe how the ability of students' mathematical literacy in solving mathematical problems in the PISA model uses the Palembang context. The research subjects were 10th class in senior high school students. The data collection techniques used are written tests, observations, and interviews. The third technique is used to find out what mathematical abilities that arise when students work on mathematical problems in the PISA model using the Palembang context. There are seven mathematical abilities that emerge, such as 84% communication skills; 88,63% mathematical abilities; 100% representation ability; 68,21% reasoning and argument skills; 86,35% ability to choose strategies to solve problems; 70,45% ability to use symbolic, formal language, and techniques and operations; and 68,17% ability to use mathematics tools so that it can be concluded that the 10th class in senior high school students, who were the subjects of the study had mathematical literacy skills that were good enough.

Penelitian ini bertujuan untuk (1) mendeskripsikan kemampuan literasi matematis dan self-efficacy siswa kelas XI SMA; (2) mendeskripsikan dampak perbedaan kebijakan sistem zonasi terhadap kemampuan literasi matematis dan self-efficacy siswa kelas XI SMA; dan (3) mendes­kripsikan hubungan antara literasi matematis dan self-efficacy siswa kelas XI SMA. Penelitian survei ini melibatkan 346 siswa dari Kota Banjarmasin dan 321 siswa dari Kota Palangka Raya. Kedua kota tersebut memiliki kebijakan zonasi yang berbeda. Pengumpulan data dila­kukan me­lalui tes dan angket yang telah memenuhi kriteria valid dan reliabel. Teknik analisis data yang digunakan adalah statistik deskriptif dan inferensial. Hasil penelitian menunjukkan bahwa literasi matematis siswa di Kota Banjarmasin dan Kota Palangka Raya berada pada kategori ren­dah, sedangkan self-efficacy siswa pada kedua kota berada pada kategori sedang. Tidak terdapat per­bedaan yang bermakna pada rata-rata literasi matematis antara siswa di Kota Banjarmasin dan Palangka Raya. Namun demikian, terdapat perbedaan yang bermakna pada rata-rata self-effi­cacy antara siswa di Kota Banjarmasin dan Palangka Raya. Kebijakan zonasi di Kota Palangka Raya menyebabkan perbedaan rata-rata literasi matematis siswa pada sekolah kategori tinggi, sedang, dan rendah. Sedangkan kebijakan zonasi di Kota Banjarmasin menyebabkan perbedaan rata-rata self-efficacy siswa pada sekolah kategori tinggi, sedang, dan rendah. Terakhir, terdapat korelasi positif yang signifikan (meskipun lemah) antara literasi matematis dan self-efficacy siswa kelas XI SMA di Kota Banjarmasin dan Kota Palangka Raya (r = 0,194). Mathematical literacy and self-efficacy of students in terms of differences in zoning system policies.AbstractThis study aimed to (1) describe the mathematical literacy abilities and self-efficacy of eleventh-grade senior high school students; (2) describe the impact of differences in zoning system policies on the mathematical literacy and self-efficacy of eleventh-grade senior high school students; and (3) describe the relationship between mathematical literacy and self-efficacy of eleventh-grade senior high school students. This survey involved 346 students from Banjarmasin City and 321 students from Palangka Raya City, Indonesia. The two cities have different zoning policies. The data was collected through tests and questionnaires that met the valid and reliable criteria. The data analysis technique used was descriptive and inferential statistics. The results showed that students’ mathematical literacy in Banjarmasin and Palangka Raya City was in a low category, while self-efficacy in both cities was in the medium category. There was no significant difference in the mean of mathematical literacy of students in Banjarmasin and Palangka Raya City. How­ever, there was a significant difference in the mean of self-efficacy of students in Banjar­masin and Palangka Raya City. The zoning policy in Palangka Raya City causes differences in the mean of mathematical literacy of students in high, moderate, and low category schools. In contrast, the zoning policy in Banjarmasin City causes differences in the mean of self-efficacy of students in high, medium, and low category schools. Lastly, there was a significant positive correlation (al­though weak) between mathematical literacy and self-efficacy of eleventh-grade senior high school students in Banjarmasin and Palangka Raya City (r = 0.194).

Introduction: The need of desks and chairs at school which appropriate with student’s anthropometry are very important. Desks and chairs which not suit with student’s anthropometry will lead to fatigue. At Kabupaten Gresik, the provision of desks and chairs which suit with student’s anthropometry still less in number. This study was aimed to provide recomendation for an ergonomic desk and chair prototype to improve seating position on senior high school students at Kabupaten Gresik. Method: This was preexperiment research with one group pre post test design. Research subjects were students at SMAN 1 Menganti and SMAN 1 Cerme, Kabupaten Gresik, 139 students were involved. Result: The recomendation of ergonomic desks and chairs specifi cation according to student’s anthropometry were: 1) Prototypechair N, length = 48 cm, wide = 43 cm, cushion base’s height from floor surfaces = 47 cm, bag keeper’s height from floor surfaces =3cm, bag keeper’s wide= 43 cm, bag keeper’s length = 47 cm, cushion’s wide = 41 cm, cushion’s length = 46cm, handrest’s height = 22 cm, handrest’s length = 30 cm, backrest’s height = 38 cm, backrest’s wide = 43 cm, cushion’s foam thickness = 4 cm, backrest’s foam thickness = 4 cm; 2) Prototype desk N, length = 50 cm, wide = 66 cm, back section’s height = 85 cm, front section’s height = 75 cm, footrest from fl oor surfaces = 10 cm, drawer’s height = 10cm, front bamper’s height = 40 cm, and table’s angle = 10o. Discussion: An ergonomic desks and chairs are very important for students at school, it will help teaching learning process run well and comfortable. The measurement of desk and chair must be reviewed after fi ve years, because of student’s anthropometric development. So then students will feel no fatigue.Keywords: ergonomy, senior high school student’s seating position

Penelitian ini bertujuan untuk menganalisis kemampuan penalaran proporsional siswa SMA dalam memecahkan masalah matematika. Subjek pada penelitian deskriptif kualitatif ini adalah 3 siswa kelas X SMA Negeri 2 Salatiga berkemampuan matematika tinggi. Instrumen utama adalah peneliti sendiri, didukung oleh instrumen tes dan pedoman wawancara. Data hasil tes dan wawancara dianalisis menggunakan langkah reduksi data, penyajian data, dan penarikan kesimpulan. Hasil penelitian menunjukkan bahwa ketiga subjek memiliki kemampuan penalaran proporsional yang berbeda dalam memecahkan masalah matematika. Kemampuan penalaran proporsional subjek S cenderung berada pada level 1 dengan menunjukkan strategi menggunakan gambar dan membuat perbandingan kualitatif. Kemampuan penalaran proporsional subjek F cenderung berada pada level 2 dengan menunjukkan strategi menghubungkan model melalui perhitungan numerik, menggunakan unit komposit, dan menggunakan penalaran kuantitatif. Kemampuan penalaran proporsional subjek M cenderung berada pada level 3 dengan menunjukkan strategi menggunakan cara formal dan mengetahui hubungan invarian dan kovarian. Ketiga subjek menunjukkan kemampuan penalaran proporsional pada level 0 dalam memecahkan masalah yang memerlukan perbandingan aditif dan multiplikatif dengan hanya menggambarkan situasi perubahan dalam pandangan aditif.
