The engaging of early age children in environmental behavior through wayang kancil folktale

School is a medium to solve the waste problem through clean lifestyle psychoeducation. Wayang kancil folktale uses animal characters as an alternative method to teach early age children to reduce littering behavior. This approach is applied because the animal world is close to the children's world. In addition, an interaction between children and the storyteller through folktale occurs during wayang kancil show. This study is action research which involves 14 second-year nursery student from a pre-school institution in Yogyakarta. The A-B-A experiment design puts the hypotheses of wayang kancil folktale to stimulate littering behavior at an early age to the test. Baseline, intervention, and reversal measurement was conducted consecutively for nine days which was recorded in observation sheets. Comprehension test was carried out before and after the intervention. The observation result was analyzed using visual analysis. Meanwhile, a comprehension score is rated by implemented paired sample t-test. The coefficient of reliability test of inter-rater was 0.971. Pre and post-intervention comprehension score increased rapidly (p = 0.000; < 0.01). The result proves that wayang kancil folktale was able to reduce children’s littering behavior.

This study aims to determine the effect of the Type STAD Cooperative Learning model on mathematical problem solving abilities. The data collection technique was obtained by means of a test in the form of description questions and documentation in the form of a list of student names. The research instrument used was 3 pre-test and post-test questions. The data analysis technique used is the normality test, homogeneity, t test with the technique of paired samples t-test and independent t-test. The results showed that, the paired sample t-test on the problem solving ability before and after treatment with STAD obtained an average value of 50.29 to 83.71 with a significance of 0.000 <0.05. This means that the students' scores before and after STAD learning have differences in the average mathematical problem solving abilities. Based on the results of the paired sample t-test on the ability to solve mathematical problems before and after treatment using conventional learning models, the average value was 44.57 to 75.79 with a significance of 0.000 <0.05. This means that there is a significant increase before and after conventional learning. Based on the results of the independent samples t-test, the mean values were 83.71 and 75.79 with a significance value of 0.009 <0.05. This means that there is a difference in the average problem-solving ability of students in STAD learning with students in conventional learning. It can be concluded that the STAD type of cooperative learning model has an effect on students' problem solving abilities in mathematics.

Abstract: Chloride as the major anion in the extracellular fluid plays a role in maintaining fluid and electrolyte balance. One of the factors that influence the levels of serum chloride is sweating during physical exercise. This study aimed to determine the differenceof serum chloride levels before and after moderate intensity exercise in the students of Faculty of Medicine year 2010 Sam Ratulangi University. This is a pre-exsperimental research with pretest and posttest design with 30 students as samples. The samples were chosen using purposive sampling method and the results were analyzed using paired-sample t-test. The results showed the average levels of serum chloride before and after moderate intensity exercise are 106,10 mEq/L and 107,37 mEq/L while paired-sample t-test significance value (p) is 0,000. From the results can be concluded that there is a significant differences in serum chloride levels before and after moderate intensity exercise in the students of Faculty of Medicine year 2010 Sam Ratulangi University.

Abstrak Latihan fisik yang berlebihan dapat meningkatkan produksi radikal bebas di dalam tubuh. Peningkatan radikalbebas ini kalau tidak dinetralisasi oleh antioksidan di dalam tubuh, maka terjadilah stres oksidatif yang dapatmenyebabkan terjadinya peroksidasi lipid, sehingga menghasilkan produk senyawa F2-isoprostan yang dapatberdampak terhadap berbagai masalah kesehatan. Tujuan penelitian ini adalah untuk menentukan pengaruhpemberian susu coklat terhadap kadar F2-isoprostan. Penelitian ini merupakan eksperimental pre and post test controlgrup design terhadap 36 siswa atlet, yang memenuhi kriteria inklusi dan ekslusi. Subjek dibagi dua kelompok yaituyang diberikan perlakuan susu coklat dan kontrol susu putih. Susu diminum setelah latihan fisik rutin atlet sebanyaksatu kali sehari selama 15 hari. Kadar F2-isoprostan dinilai sebelum dan sesudah secara ELISA. Data dianalisisdengan paired sample t-Test, bermakna bila p<0,05. Hasil penelitian didapatkan rerata kadar F2-isoprostan sebelumperlakuan pada kelompok susu coklat adalah 65,98±14,61 pg/ml dan sesudah perlakuan adalah 45,55±13,74 pg/ml.Rerata kadar F2-isoprostan sebelum perlakuan pada kelompok kontrol susu putih adalah 54,24±20,44 pg/ml dansesudah perlakuan adalah 48,80±20,23 pg/ml. Kesimpulan yang diperoleh ada pengaruh yang bermakna dari reratakadar F2-isoprostan sebelum dan sesudah perlakuan baik pada kelompok perlakuan susu coklat dan kelompok kontrolsusu putih.Kata kunci: latihan fisik, radikal bebas, F2-isoprostan, susu coklatAbstract Excessive physical exercise can increase the production of free radicals in the body. The increase in freeradicals if not neutralized by antioxidants in the body and it caused oxidative stress which can cause lipid peroxidation,resulting in F2-isoprostane product compounds that can affect a variety of health problems. The objective of this studywas to determine the influence of milk chocolate on F2-isoprostane levels. This study was an experimental pre andpost test control group design to the 36 student athletes, who meet the inclusion and exclusion criteria. The subjectswere divided in two groups: the treatment given milk chocolate and white milk is given control, drunk after a routinephysical exercise athlete, once a day for 15 days. F2-isoprostane levels were assessed before (pre) and after (post) byELISA, the data were analyzed by Paired Sample t-Test, significant if p <0.05. The results showed average levels ofF2-isoprostane before treatment group was 65.98 ± chocolate milk 14.61 pg / ml and after treatment was 45.55 ±13.74 pg / ml. Average F2-isoprostane levels before treatment in the control group was 54.24 ± white milk 20.44 pg /ml and after treatment was 48.80 ± 20.23 pg / ml.

And Control

The farmers in Indonesia have not maximally taken advantage of the existence of rice husk; therefore the huge number of the husk becomes disturbing waste, which spoils environment. The waste of rice husk is potentially capable of improving the farmers’ economy amidst the people’s lack of knowledge about its potential to commercially produce charcoal briquettes from it, make it a plant growing medium, and change it into manure. This research aims at knowing if the training of recycling waste of rice husk can improve the farmers’ entrepreneurship motivation. The subjects of the research were farmers in groups at Bimomartani village, Ngemplak district, Sleman regency. They were 60 participants divided into experintal and control groups. The planned experiment used untreated control group design with dependent pretest and posttest samples. The paired sample t-test and independent sample t-test were used as the techniques of analysis in this research. The result of t-test on paired sample t-test for the experimental group resulted in the value of t = -6.659 with p = 0.000 (p<0.01), which means there was a significant difference of entrepreneurship motivation before and after the training of recycling rice husk. The analysis for Independent sample t-test resulted in the value of t = 7.411 with p = 0.000 (p<0.01), which means there was a significant difference of entrepreneurship motivation between experimental and control groups. It can be concluded that the training of recycling waste of rice husk was effective in improving the farmers’ entrepreneurship motivation.
