Buyung dance is rarely displayed and has begun to be unknown to the public. Also, children, today prefer foreign culture and dance. As a result, the existence of Buyung dance is only limited to recognition, without the benefits that can be felt. The absence of written guidelines in each of the Buyung dance movements is very interesting for researchers to analyze the relationship of the Buyung dance movements with mathematics. This type of research used in this study is qualitative research. In qualitative research, the instrument is the researcher himself and cannot be replaced by others. Data collection techniques used in this study through the method of observation, interviews, and documentation. Every hand movement of the dancers and movements between dancers to one another makes the movements of the dances neat and attractive following the Frieze Group, with four frieze patterns found in the dances of the pitchers.

AbstrakPenelitian ini bertujuan untuk melihat pengaruh konsentrasi kalsium klorida (CaCl2) dan lama perendaman terhadap umur simpan dan pematangan buah mangga (Mangifera indica L) Cv. Manalagi. Penelitian ini mengunakan Rancangan Acak Lengkap (RAL) pola factorial terdiri atas 2 faktor, yaitu faktor A (konsentrasi kalsum klorida dengan taraf a1 konsentrasi 5%, a2 10% dan a3 20%) dan faktor B (lama perendaman dengan taraf b1 lama perendaman 1 menit, b2 15 menit, b3 30 menit, dan b4 60 menit) dengan 12 kombinasi perlakuan dan 3 ulangan. Data yang diperoleh tersebut dianalisis menggunakan ANAVA. Hasil analisis data tersebut menunjukkan bahwa F hitung ≤ F tabel sehingga Ha ditolak artinya konsentrasi kalsium klorida dan lama perendaman tidak berpengaruh terhadap umur simpan dan pematangan buah mangga (Mangifera indica L) Cv. Manalagi, karena disebabkan oleh beberapa faktor diantaranya suhu, waktu pemetikan dan tingkat kematangan buah yang digunakan.Kata Kunci: Konsentrasi, kalsium klorida, buah mangga (Mangifera indica L) Cv. Manalagi.

Increased economic growth and the number of new industries resulted in the expansion of employment opportunities for both men and women, and did not prioritize job skills requirements that specifically attracted women to work. In modern times, female workers are more dominant than male workers. Workers should get legal protection to guarantee and protect their rights as workers. Workers' protection itself is regulated in Law No. 13 of 2003 which was changed to Law No. 11 of 2021 on Job Creation. The Sidoarjo regional government should monitor and supervise the implementation of laws that protect the rights of women workers in Sidoarjo so that it can be known and assessed whether the implementation of the applicable laws is appropriate or not, and efforts can be made to increase legal protection if it is not appropriate.

Buyung dance is a traditional Sundanese dance that reflects the Sundanese community in taking water. Also, the meaning of a pitcher is a kind of tool made of metal or clay often used by some village women in earlier times to take water in rivers, lakes, or ponds. When viewed closely, the Buyung dance formation has mathematical concepts such as the field of geometry, transformation of the geometry, and the counts and measurements made by the dancers in performing the Buyung dance. Besides, each formation also has its philosophical significance. This research is a qualitative study. The researcher directly goes to the field, studies a natural process of discovery through the process, records, analyzes, interprets, and reports, and draws conclusions from the process. Data collected through observation, interviews, and documentation. Based on the research, it was concluded that the beauty of the formation in the pitcher dance was identical to the pattern of the Frieze group. Also, the formation formed has a philosophical meaning that reflects the local wisdom of the local community.

ABSTRAK: Permasalahan pelaksanaan pembelajaran biologi di kelas VIIIB SMPN 3 Batukliang Utara tahun pelajaran 2016/2017 adalah keterampilan berpikir kreatif dan hasil belajar kognitif siswa masih kurang memuaskan, terbukti dengan adanya nilai MID semester yang di bawah KKM (Kriteria Ketuntasan Minimal). Disebabkan oleh proses pembelajaran tidak berjalan efektif karena penggunaan model pembelajaran yang tidak efektif. Tujuan penelitian ini adalah untuk mengukur pengaruh model pembelajaran Reciprocal Teaching dengan Teknik Example Non Example terhadap aktivitas dan hasil belajar kognitif siswa pada materi pokok sistem pencernaan pada manusia kelasVIIIB SMPN 3 Batukliang Utara. Instrumen yang digunakan dalam penelitian ini adalah lembar observasi untuk aktivitas belajar siswa dan tes untuk hasil belajar kognitif siswa. Hasil penelitian menunjukkan bahwa terdapat peningkatan aktivitas belajar siswa, untuk rata-rata aktivitas belajar siswa pada kelas kontrol sebesar 2,9 yang termasuk dalam kategori cukup aktif, sedangkan untuk kelas eksperimen sebesar 3,5 dengan kategori aktif. Hasil post-test belajar kognitif siswa memperoleh nilai rata-rata pada kelas eksperimen yaitu 85,8 dan kelas kontrol yaitu 80. Analisis uji-t pada taraf signifikansi 5% diperoleh t hitung sebesar 3,12 sedangkan nilai t tabel dengan dk = 54 sebesar 2,05. Ini berarti bahwa nilai t hitung lebih besar dari nilai t tabel (3,12 > 2,05). Dengan demikian dapat disimpulkan bahwa ada pengaruh model pembelajaran Reciprocal Teaching dengan Teknik Example Non Example terhadap hasil belajar kognitif siswa. Kata Kunci: Model Reciprocal Teaching, Teknik Example Non Example, Aktivitas, Hasil Belajar Kognitif Siswa. ABSTRACT: The problem of implementing biology learning in class VIIIB SMPN 3 NorthBatukliang 2016/2017 school year is creative thinking skills and student cognitive learning outcomes are still not satisfactory, as evidenced by the existence of MID semester scores under the KKM (Minimum completeness criteria). Caused by the learning process not running effectively because of the use of ineffective learning models. The purpose of this study was to measure the effect of the Reciprocal Teaching learning model with the Example Non Example Technique on the cognitive activities and learning outcomes of students on the subject matter of the digestive system in humans class VIII SMPN 3 North Batukliang. The instrument used in this study was an observation sheet for student learning activities and tests for student cognitive learning outcomes. The results showed that there was an increase in student learning activities, for an average student learning activity in the control class of 2.9 which was included in the quite active category, while for the experimental class by 3.5 with the active category. The results of students' cognitive learning post-test obtained an average value in the experimental class of 85.8 and a control class of 80. The t-test analysis at the significance level of 5% was obtained tcount of 3.12 while the value of ttable with dk = 54 of 2...
