Full text linkAbstract. The purpose of this study is to explore ethnomatematics in the activities of cocoa farmers to create the teaching materials for students in the form of the packages of test. The type of research was qualitative research with ethnographic approaches. The data collection method used were observation and interview. The research subjects were six people. The ethnomatematics included the activity of counting, measuring, and designing. This study focused on determining the estimated number of trees based on its distance and area by using stakes (patok), determining the fertilization model based on the fertilization time and the planting age, determining the number of workers based on the land area, and estimating yields. The emerging mathematical concepts were comparison and social arithmetic.

ANALISIS PENGGUNAAN MEDIA VIDEO PEMBELAJARAN ETNOMATEMATIKA TARI JEJER GANDRUNG KEMBANG MENUR SEBAGAI HASIL BELAJAR SISWA
Full text linkAbstract: Mathematics has an important role in education and other sciences. Generally learning mathematics seems conventional and theoretical, so students assume that mathematics seems stiff, difficult, and boring. Education can be combined with local culture in creating a more contextual education atmosphere, especially in the mathematical concept commonly referred to as ethnomatematics. This study aims to examine the use of video media for learning ethnomatematics Traditional Dance of Gandrung Kembang Menur typical of Banyuwangi on increasing student interest in learning. This study uses qualitative methods, the data obtained is the result of pre-test and post-test with 8 multiple choice questions. The results showed that there was an utilization of Etnomatematics learning video media on the Jejer Gandrung Kembang Menur dance typical of Banyuwangi in the process of influencing student learning outcomes.

PENGEMBANGAN INSTRUMEN INTEGRATED SCIENCE TEST TIPE PILIHAN GANDA BERALASAN UNTUK MENGUKUR HOTS PESERTA DIDIK
Full text linkHOTs is the main purpose of 21st-century science learning. Individu with HOTs will able to make a connection between facts and concepts, apply it into any new situation to solve the problem. The aim of this research was to developed integrated science test instrument to measure HOTs level of junior high school students. Oriondo and Antonio models’ was adapted and used in this research method. The test was developed in the reasoning-multiple choice form with three category based on PISA and Marzano HOTs competencies. The item analysis involved content validity, empirical validity, reliability, and difficulty index. Rasch model analysis through Quest and Ministep software output showed (1) Mean of INFIT MNSQ level at 1.00±0.12 that shows fit item with Rasch Model or empirical validity of items; (2) Level of INFIT MNSQ for all item between 0.77 and 1.33; (3) Vary of difficulty index; 34 items were at difficulty index level between -2 and +2; (4) junior high school students’ HOTs in SMP IT Multazzam Banyumanik was at low level because they are difficult in giving explanations or arguments about the options that have been selected. Thus, the integrated science test instrument developed can be used to measure students' HOTs
PENERAPAN MODEL PROBLEM BASED LEARNING DISERTAI VIDEO TRACKER MATERI MOMENTUM DAN IMPULS UNTUK MEMBELAJARKAN KEMAMPUAN BERPIKIR KRITIS SISWA DI SMA
No full textAbstract: This study aims to describe the level of critical thinking ability of a high school students in Situbondo after the application of problem based learning model with a tracker video on momentum and impulse materials. The population were all of the 1st grade students in SMAN 1 Suboh Situbondo. The sample determination were using purposive sample technique. The sample used was X MIPA 2 and X MIPA 4 class. The results concluded that after the application of problem based learning model with tracker video, the level of student’s critical thinking abilities is good. From the six critical thinking indicators, namely interpretation, analysis, evaluation, inference, explanation and self regulation, the indicator that has the highest percentage is interpretation with a very good category. While the indicator that has the lowest percentage is inference in the good category.

TEMUAN MENARIK HASIL EKSPLORASI ETNOMATEMATIKA PADA BATIK GAJAH OLING BERDASARKAN KONSEP GEOMETRIS
Full text linkAbstract. Ethnomatematics as link between culture and mathematics is a multicultural mathematical activity that uses culture in making connections with mathematics topics so as to motivate students to preserve their own culture while learning mathematics. The purpose of this reasearch are to explore ethnomathematics in Gajah Oling’s batik based on geometric concepts. The type of reaserch is qualitative with an ethnographic approach. Data collection methods used are observation and interviews. The subject of this reasearch is a design maker Gajah Oling’s batik. This research focuses on intersesting discovery from the exploration results, that is making pattern of Gajah Oling’s batik shirt. In the process of making pattern of Gajah Oling’s shirt, ethnomathematics seen on design and measuring activities. In desiging activities geometric concepts such as translation and reflection emerge, while in measuring activities, design makers use mathematics to determine the design size so that the fabric meeded to make a shirt can be minimized as little as possible.Keywords: Ethnomatematics, cocoa farmers, culture.

PEWARNAAN SISI r-DINAMIS PADA GRAF HASIL OPERASI AMALGAMASI TITIK KELUARGA GRAF POHON DAN KAITANNYA DENGAN KETERAMPILAN BERPIKIR TINGKAT TINGGI
Full text linkAbstract. Pewarnaan sisi dinamis suatu graf didefinisikan sebagai pemetaan dari ke himpunan warna sedemikian hingga memenuhi kondisi dan dimana adalah himpunan sisi yang bertetangga dengan dan adalah derajat titik . Nilai yang minimal sehingga graf memenuhi pewarnaan warna sisi dinamis disebut bilangan kromatik sisi dinamis, yang dinotasikan dengan Penelitian ini, peneliti menentukan bilangan kromatik pada graf hasil operasi amalgamasi titik dari keluarga graf pohon yaitu graf bintang dan graf sapu menggunakan metode deduktif aksiomatik. Hasil dari penelitian ini adalah teorema yang menyatakan bilangan kromatik pewarnaan sisi dinamis. Terdapat tiga teorema yang dihasilkan dari graf yang diteliti serta setiap tahap dalam penelitian ini dikaitkan dengan keterampilan berpikir tingkat tinggi.

HUBUNGAN KUALITAS BIOLOGI, KIMIA, FISIKA AIR SUMUR DENGAN KEPADATAN PENDUDUK DI KABUPATEN JEMBER
Full text linkBiologically, clean water can be said to be suitable for use if the water does not contain pathogenic microorganisms that are harmful to human health. Chemically, consumable water is water that has a pH of 6.5-8.5. Physically it also needs attention. This study aims to find out how the relationship between the quality of biology, chemistry, physics, in Jember Regency well water based on the Republic of Indonesia PERMENKES No.492/MENKES/PER/IV/2010". The research begins with taking samples using purposive sampling technique. Then do the MPN test, acidity test (pH), organoleptic test, TDS test, and dissolved oxygen (DO) test for each sample. Based on the results of the correlation analysis it was found that there was no relationship between biological quality and population density and there was a relationship between the quality of physics and population density and there was no relationship between chemical quality (pH) but between chemical qualities (DO) with population density there is a relationship
PENGEMBANGAN ALAT KONDENSASI PENGUKUR OKSIGEN UDARA AMBIEN UNTUK MENDUKUNG PRAKTIKUM PADA MATA KULIAH PENGETAHUAN LINGKUNGAN
Full text linkAbstrack: At present it is using digital air measurements using much better analytical functions in the field using digital measurements that have accuracy weaknesses. Developing a condensation device into the air oxygen meter uses two methods: prioritizing Saltzman and Winkler, this corresponds to the contents in the air directly with air and oxygen. Development of atmospheric atmospheric condensation equipment for example ambient air oxygen concentration measuring generator, carried out with the R2D2 development model with a calibration process based on independent sample test Calibration T-test error test with digital titration and electrochemical methods, In addition to the significance of the measurement result is sig value 0.280 > 0, 05 and the calibration measurement results of the tool developed with a digital meter tool obtained the significance of the results that the sig value of 0.254 > 0.05 there was no difference between several samples using the method used.
