Abstract

The aim of this research is to improve interests and outcome of learning Mathematics of Eighth grade students of SMP Taman Dewasa Pawiyatan Yogyakarta, employing the Small Group Work model. Action Hypothesis proposed in this study is that the Small Group Work model is able to enhance the interest and outcome of learning Mathematics of the Eighth grade students of SMP Taman Dewasa Ibu Pawiyatan Yogyakarta. The research applies the Classroom Action Research, particularly using apparent experiment conducted, at least, in 2 cycles. The subject appointed is the Eighth grade students of SMP Taman Dewasa Ibu Pawiyatan Yogyakarta. There are 19 students consisting of 9 male students and 10 female students. The object opted is Mathematics learning through Small Group Work model to determine their interest and the outcome of Mathematics learning in Algebra operation. The required data is gathered through using observation sheets, questionnaires, tests, field documentation and notes. The instruments are assessed using validity and reliability tests. The research findings indicate that the application of Small Group Work model is proven to improve students’ interest and their learning outcome. This can be presented by the increasing of student’s interest average percentage based on the observation sheets in each cycle. In the first cycle, the students’ interest is as much as 62,71%, and for the second cycle achieves 79,82%. It is also supported by the questionnaire data that shows the increasing number in the first to the second cycle, from 79,83% to 85,11%. The increasing fashion also takes place in the students’ Mathematics average score. The average score for the first cycle is 48,42 up to 58,95, and for the second cycle turns to 71,84. It is confirmed in this research that the Small Group Work model can enhance students’ interest and the Mathematics learning outcome. It is expected that teachers can put this learning model in practice.

Abstract

The aims research to find out the stages of good rice seed will be planted, to know the time calculation in Java to plant rice, and to complete the model and general mathematical solution by calculating the number of rice seeds involving the area of rice fields (10.000 m ^ 2). This type of research used qualitative research with ethnography approach. Research subjects namely Mbah and Pakde in Baratan village who work a rice farmer. This study uses interview guidelines. The results obtained from the interview data that is to determine the stage of good rice seed will be planted is to plow the field using a hoe, soaking rice seeds for 48 hours, sort the results of good rice immersion, curing for 48 hours to germinate, sow seeds evenly, after 20 days of paddy seedlings removed and planted, 1 week given urea fertilizer, 45 days fertilized again, and 3 months ready for harvest, while for the calculation of time in good Java language to plant rice that is prey ketelu on 25 August - 18 september (24 days ). The result of the mathematical model and solution associated with calculating the amount of rice involving the paddy area is obtained by the area of rice field (10.000m 2), the number of rice seeds needed is more.
