Abstract

In Indonesia, increased critical land reached 24 million hectares, showed that the rate of damage landresources is worried due to the less- controlled management. Thus, the widespread critical land need to beidentified to set the factors causes.Various type of land used as an indicator of damaged, so it takes effort torestore critical land into potential land. One of solution is harnessing the earthworm interaction pattern withenvironment. Earthworms as a decomposers of ground plant litter and soil organic matter, then digested andexcreted in the form of casting. The ability of these animals in consuming ground plant litter as a food wasdepend on the availability preferred of the litter,ultimately depend on carbon and nitrogent suply. Earthwormfeces is called casting, allegedly contains nutrients levels of N, P, and K. Understood that earthworms arepotentially to expounds of organic matter into small particle. The observation showed that soil had earthwormwith large quantities supposed the soil fertility caused create aeration and prevented on soil compaction.Earthworms in turn stimulate soil nutrient mineralization and s oil organic material saving. Organicmaterials improving the physical soil, biological soil and increase the nutrient suply for plants. In the cycle oforganic materials, earthworm as a fragmentator, as an fragmentation of the decomposition process of plantlitter in the soil surface. The ground plant litter in the moist soil undergoes fragmentation much faster thandry soil. The earthworms also as stimulator humification, the process of destruction and mixing of chemicallyagainst particles of organic into humus. Generally, the diversity of earthworms sustainability of ecosystemexposure to elevated carbon and mediated nitrogen cycling, as well as modify the structure of the soil andmoisture. In ecosystem, the interactions between component has mutual effect and dynamic relation. Thismeans that the relationship between components isn’t simple and static, but extremely variable and changed.

Abstract

The purpose of this research is to know the effect of brainstorming actvity in Learning Cycle 5E learning model towards sciencetific literacy ability aspect of scientific nomenclature, rules of scientific evidence, postulate of science, scientific disposition, major misconception about science and, intellectual process skills. The research method is experimental research with Randomized Posttest-Only Control Group Design. The research population is all students of class XI IPA SMA Negeri 2 Karanganyar. The sample of research choosed with simple ramdom sampling technique and obtained two classes namely class XI IPA 4 as experiment class and XI IPA 1 as control class. Data collection techniques use tests and observations. Normality and homogeneity test are performed as a requirement of hypothesis test. The data analysis technique used Manova test and advanced testing using Tukey test.The research procedure includes planning, implementation and data analysis.Based on the result of the research, it can be concluded thatthere is effect of brainstorming actvity in Learning Cycle 5E learning model towards sciencetific literacy ability on aspect of scientific nomenclature, rules of scientific evidence, postulate of science, scientific disposition, major misconception about science and, intellectual process skills. The effect of brainstorming actvity in Learning Cycle 5E learning model on aspects of sciencetific literacy ability from highest to lowest is scientific disposition more than postulate of science, scientific nomenclatur equal to postulate of science, then major misconception about science and intellectual process skills.

Abstract

The purpose of this research is to improve students internalization character through the implementation of learning model SETS (Science Environment Technology and Society) in class XI IPA 2 SMA Muhammadiyah 1 Karanganyar academic year 2016/2017. This research is an action research (Classroom Action Research), was held two cycles. Each cycle consists of three stages: planning, execution and observation, and reflection. The subjects were students of class XI IPA 2 SMA Muhammadiyah 1 Karanganyar academic year 2016/2017. The data research obtained through observation, tests, self-assessment questionnaires and friends, and interviews. The validity of the data using triangulation techniques. Analysis of data using qualitative descriptive analysis techniques. The research procedures using spiral model Kemmis and Mc Taggart. Aspects of the character values of students researched were honest, disciplined, hard working, creative, independent, curious, caring environment, and responsibility. The results of attitude observation 76.9%, student self-assessment 80.8%, and friend assessment 76.5%. Student achievement scores on internalizing character prasiklus 41,3%, 60,8% the first cycle and the second cycle 78.1%. Based on these research it can be concluded that the implementation of learning models SETS (Science Environment Technology and Society) can improve the character internalization towards the eleventh grade students of science 2 program (XI IPA 2) at SMA Muhammadiyah 1 Karanganyar.
