This research is motivated by the mathematical self-concept of students in learning mathematics is not yet formed with positive self concept and this is influenced by many factors, one of which is the teacher factor. A teacher must be able to create a learning atmosphere that is meaningful, fun, creative and dynamic through the use of appropriate learning models one of which is the learning model Accelerated Learning Cycle is a learning model that creates a learning process environment that is meaningful and promotes the emergence of positive emotions. The formulation of the problem is Is there a significant influence on the application of the accelerated learning cycle learning model to students' mathematical self-concepts? This research is a quantitative study using the Quasi-experimental method, the type of experimental design is the quasi experimental design method with the type of Pretest-Posttest Control Group Design in two different classes which are divided into experimental and control classes. class VII 3 totaling 31 students and VII 11 totaling 34 students. Then the data collection instrument was a questionnaire that was given twice, that is before being treated and after being treated. Analysis of the data used is descriptive and inferential statistical formulas namely normality test and hypothesis testing with paired sample t-test. In accordance with the hypothesis testing using the Paired Sample t-test, the value of t thitung = 37.177 is greater than ttabel = 2.03452 then according to the basis of decision making in the t test, it can be concluded that H0 is rejected and Ha is accepted at the 5% significance level (α = 0.05) this shows that there is a significant effect of the application of the accelerated learning cycle learning model to students' mathematical self-concepts

AbstractThe purpose of the study was to analyze the differences in the increase in self-concept of elementary school students through scaffolding techniques in Saparua District, Central Maluku Regency, Maluku Province. The method used was a quasi-experimental design with one group pretest-posttest and involved 30 elementary school students as research samples. The test uses paired sample t-test and it is identified that there are differences in students' self concepts before and after scaffolding techniques are applied. Self-concept enhancement was analyzed using N-gain, where each self-concept indicator achieved an increase in the medium category. The indicators of attitude and self-confidence increased by 31%, The indicators of View of ability and disability increased by 43%, and indicators of self-sensitivity increased by 52%, and the indicators of views of others towards themselves was 45%. These result are due to the effectiveness of scaffolding, because by scaffolding students can be helped to solve a problem.

Anemia terjadi di seluruh dunia, terutama di negara berkembang dan pada kelompok sosio-ekonomi rendah, yaitu pada 45 % wanita. Anemia merupakan salah satu penyebab tidak langsung kematian ibu. Berbagai upaya dilakukan, namun belum menunjukkan hasil maksimal. Perlu upaya lain berupa pemberian jus alpukat untuk mengatasi anemia kehamilan. Penelitian ini bertujuan mengetahui pengaruh pemberian jus alpukat terhadap kadar hemoglobin dan jumlah eritrosit ibu hamil. Jenis penelitian Quasi experimental design, dilaksanakan bulan November s.d. Desember 2017 di Puskesmas Sindang. Jumlah responden 33 ibu hamil trimester II, kadar Hb < 11 g/dL ditentukan dengan purposive sampling. Responden mengisi kuesioner, kemudian dilakukan pemeriksaan kadar Hb dan jumlah eritrosit 3 kali yaitu pre, hari ke-7, dan 14 setelah intervensi. Analisis data dilakukan secara deskriptif, analisis bivariat menggunakan independent dan paired sample t-test serta analisis mulitivariat menggunakan repeated measures ANOVA. Mengonsumsi jus alpukat selama 14 hari efektif meningkatkan kadar Hb dan jumlah eritrosit. Hasil uji beda tidak terdapat perbedaan kadar Hb dan jumlah eritrosit antara kelompok kontrol dengan intervensi. Hb rata-rata kelompok kontrol 10,375 g/dL sedangkan intervensi 10,653 g/dL (nilai p=0,986). Jumlah eritrosit rata-rata pada kelompok kontrol yaitu 3,455 juta/mm3 sedangkan intervensi 3,614 juta/mm3 (nilai p=0,763). Uji multivariat terlihat perbedaan antara kelompok kontrol dengan intervensi. Pada kelompok kontrol kadar Hb rata-rata (p=0,441) sedangkan intervensi (p=0,023). Untuk jumlah eritrosit rata-rata pada kelompok kontrol (p=1,000) sedangkan intervensi (p=0,043). Simpulan peneltian adalah terdapat pengaruh positif pemberian jus alpukat selama 14 hari terhadap peningkatan kadar Hb dan jumlah eritrosit rata-rata, namun tidak ada perbedaan antara kelompok intervensi dan kelompok kontrol. Abstrak Anemia occurs worlwide, especially in developing countries and in low socioeconomic groups. i.e. in 45% of women. Anemia is one of the causes of bleeding. Various attempts have been made, but have not shown the maximum results. Need other efforts in the nutrition form of avocado juice to overcome the anemia of pregnancy. This research aims to determine the effect of avocado juice on hemoglobin and erythrocyte levels of pregnant women. The type of this research is Quasi Experimental design which implemented in November to December 2017 with 33 respondents of trimester II pregnant women who have HB<11g/dL and determined by purposes sampling. Repondents filled out questionnaires to determine their characteristics and performed laboratorium checkup 3 times, pre, on day 7 and 14 after intervention. The data analysis was done descriptively, hypothesis testing using independent sample t-test, to know the effectiveness of avocado juice using paired sample t-test and to know the difference of mean of Hb and erythrocytes using ANOVA repeated measures test. Consuming avocado juice for 14 days was effective in increasing the average of Hb and erythrocyte levels. LSD post hoc test results showed significant differences in Hb and erythrocytes mean (Hb p-value = 0.023 and erythrocytes p-value = 0.043) in the intervention group between pre and day 14 post intervention. While in the control group p-value p= 0.441 for Hb and erythrocytes p=1.000. The conclusion of this research that there was a positive effect of consuming avocado juice for 14 days in increasing the average of Hb and erythrocyte levels, but the hypothesis test result showed that there was no significant difference between the intervention group and the control group.
