This study aimed to analyze students' conceptual understanding by using a multi-representation assisted discovery learning model in measurement. This research was conducted in Public High School 1 Kendari. This research is a quasi-experimental study using a one-group pre-post test design. The research method consisted of a conceptual comprehension test using a caliper and a screw micrometer in an essay in the form of a multi-representational test on long measurements. The analysis showed an increase in conceptual understanding between the pre-test and post-test with an average pre-test score of 16.24 (SD = 14) and a post-test of 61.4 (SD = 21). These results indicate an increase in students' understanding of concepts after learning with an average N-gain increase of 0.5 (SD = 0.2) in the medium category. It also obtained the most significant increase in students' understanding of the indicators mentioned parts caliper and micrometer with an N-gain average of 0.6 in the medium category.

AbstrakTujuan penelitian ini adalah mengetahui perbedaan kemampuan penalaran matematis siswa antara model discovery learning dan jigsaw. Jenis penelitian adalah eksperimen semu. Tempat penelitian diaksanakan di SMP Negeri 18 Kota Bengkulu. Populasi pada penelitian seluruh siswa kelas VII. Sampel penelitian dipilih secara acak sederhana yaitu kelas VII.1 sebagai kelas eksperimen 1, pembelajaran dengan menggunakan model discovery learning, kelas VII.5 sebagai kelas eksperimen 2, pembelajaran dengan menggunakan model kooperatif tipe jigsaw, dan kelas VII.3 sebagai kelas kontrol, pembelajaran dengan menggunakan model pembelajaran konvensional. Hasil penelitian ini menunjukan bahwa kelas eksperimen 1 memperoleh nilai rata-rata tes akhir (post-test) kemampuan penalaran matematis siswa yaitu 12,13, nilai rata-rata eksperimen 2 yaitu 11,45, dan nilai rata-rata kelas kontrol yaitu 9,26. Berdasarkan hasil analisis uji anava satu jalur, dengan signifikan 0,05 diperoleh 𝐹ℎ𝑖𝑡𝑢𝑛𝑔 = 𝐹𝑡𝑎𝑏𝑒𝑙 = 0,34, maka H0 ditolak. Artinya ada perbedaan signifikan rata-rata kemampuan penalaran matematis siswa pada kelas eksperimen 1, kelas eksperimen 2, dan kelas kontrol. Berdasarkan uji beda nyata (BNT) menunjukan bahwa pembelajaran yang memberikan hasil penalaran matematis yang berbeda adalah model pembelajaran discovery learning dengan konvensional, dan model kooperatif tipe jigsaw dengan konvensional. Sedangkan pembelajaran dengan model discovery learning dan model kooperatif tipe jigsaw tidak memberikan hasil kemampuan penalaran matematis siswa yang berbeda. Model discovery learning dan model kooperatif tipe jigsaw memberikan hasil lebih baik bila dibandingkan dengan model konvensional.Kata kunci: kemampuan penalaran matematis, model discovery learning, model Jigsaw AbstractThe purpose of this study was to determine students' mathematical reasoning abilities with discovery learning models and jigsaw type cooperative learning models. This type of research is quasi-experimental research. The population in this study were all students of class VII SMP Negeri 18 Bengkulu City in the   academic year 2019/2020. The sample of this study was selected by simple random sampling, namely class VII.1 as experimental class 1 using the discovery learning models, class VII.5 as experimental class 2 using the jigsaw type cooperative learning models, and class VII.3 as control class using conventional learning models. Data were collected by means of tests of students' mathematical reasoning abilities. Based on the results of the one-way ANOVA test, there are significant differences in students' mathematical reasoning abilities in the experimental class 1, experiment class 2 and the control class. The results          of the real difference test (BNT) show that learning that gives different results is the discovery learning models with conventional learning models, and the jigsaw type cooperative learning model with conventional learning models. Meanwhile, learning with discovery learning models and jigsaw type cooperative learning models does not give different results for students' mathematical reasoning abilities. Discovery learning models and jigsaw type cooperative learning models give better results when compared to conventional learning.Keywords: mathematical   reasoning   ability,   discovery   learning   model,   Jigsaw   model

ABSTRAK Rendahnya cakupan ASI eksklusif di Indonesia menjadikan anak terkurangi haknya untuk mendapatkan makanan bernutrisi tinggi bagi pertumbuhan. Hal ini dikarenakan kurangnya produksi ASI pada ibu menyusui. Pemberian tindakan non farmakologi seperti teh daun kelor diharapkan mampu meningkatkan produksi ASI sehingga anak tetap mendapatkan ASI. Penelitian ini bertujuan untuk untuk mengetahui pengaruh konsumsi teh daun kelor terhadap peningkatan produksi ASI di Kabupaten Grobogan. Metode penelitian ini berjenis quasi experimental study dengan menggunakan one group prepost test design pada 60 responden. Intervensi dilakukan selama 3 minggu untuk menilai produksi ASI antara Pre dan Post intervensi. Data dianalisa dengan menggunakan Uji Paired t-Test. Hasil penelitian menunjukkan rata-rata ASI pada tahap pre-test sebanyak 152,00 meningkat menjadi 158,50 pada tahap post-test. Terdapat perbedaan jumlah ASI dengan p-value sebesar 0,002 dengan nilai korelasi sebesar 0,934. Kesimpulan penelitian ini adalah terdapat pengaruh yang signifikan pada konsumsi teh daun kelor untuk produksi ASI.  Kata Kunci : Teh Daun Kelor, Produksi ASI

Millions of rands are spent on sponsorship in general every year, and on sports sponsorships in particular. Yet little is known about the effectiveness of this expenditure. In addition, sponsors are often not sure whether only their brands benefit from a sponsorship or whether competing brands in the same product category also benefit from their efforts.In this study an attempt is made to clarify these considerations by comparing both the brand recall and the brand recognition of companies (and brands) who sponsored the 2007 Cricket World Cup. To determine whether brand recall and brand recognition increased during a sponsorship campaign, a quasi-experimental study was conducted by means of a one-group pre-test-post-test design. The data were collected using a convenience sample of 131 undergraduate students.The results seem to suggest that both the brand recall and the brand recognition levels of the sponsors increased significantly (α = 0,05), but that neither the brand recall nor the brand recognition levels of non-sponsor brands increased. The results therefore show that sponsorship does in fact increase brand awareness, by significantly increasing unaided brand recall, as well as increasing brand recognition and that non-sponsoring companies and brands do not benefit indirectly from their competitors’ sponsorships in terms of brand recall and brand recognition.

The goal of this study is to see how problem-solving learning paradigms affect students' grasp of physics ideas. This study is a quasi-experimental study. The sample was chosen using the cluster random class methodology, which consisted of two classes, the first of which was taught using a problem-solving learning model and the second of which was taught using traditional methods. Experiment classes provide problem-solving opportunities to help students better understand physics ideas, while control classes are taught in a traditional manner. Pre- and post-test results from students in both classes were used to collect data. The two-way Anava-test was applied, and the level of significance was found to be 0.000 (sig. 0.05), indicating that problem solving learning is beneficial in improving students’ understanding of physics concepts.

Approach Problem

This study aims to obtain a comparative picture of increasing conceptual understanding between students who experience problem-based learning with a multi-representation approach and students who experience problem-based learning without a multi-representation approach. The aspects of understanding studied refer to Bloom's taxonomy, namely translation, interpretation, and extrapolation. This study used a quasi-experimental method with pre test and post test design non equivalent group design. The sample in this study were students from two class X in one high school in the city of Bandung. The experimental class consisted of 28 students and the control class consisted of 25 students. The results showed that the students' understanding of the concept increased with an average n-gain in the experimental class and control class respectively, namely 0.406 with the medium category and 0.289 with the low category.
