Abstract

[Title: The Implementation of Mindscaping Method in Physics Learning as an Effort to Improve Student Learning Outcomes]. This study aims to improve the activities and outcomes of student physics learning by applying the mindscaping method. This type of research is classroom action research conducted in three cycles. Each cycle consists of planning, action, observation, evaluation and reflection. Student learning activity data is obtained by observation while student learning outcomes data are obtained by giving objective tests at the end of each cycle. The application of the mindscaping method in this study is said to be successful if 85% of students achieve learning outcomes greater or equal to 65, while student learning activities are at least active categories. The results of the study showed an increase in student learning activities each cycle, namely in the first cycle the category was quite active to be very active in the second cycle and in the third cycle. Student learning outcomes can be seen from the classical completeness value which has increased in each cycle, each has a value of 76% in the first cycle, 80% in the second cycle, and 92% in the third cycle. Thus it can be concluded that the application of the mindscaping method has succeeded in increasing the activities and results of student physics learning.

Abstract

One of the impacts of waste management is the presence of side-residual landfill waste that causes pollution potential of pollutants results in the form of decaying garbage leachate. This contamination occurs around the landfill Kebon Kongok impacting environmental degradation around the landfill area. To determine the extent to which and how the subsurface conditions around the landfill Kebon Kongok it will do the mapping and modeling using 3-dimensional (3D) geoelectrical method. The study was conducted on 3 pieces of lines are trending relative Southwest-Northeast. Each track has a length of 150m and retrieval of data using a dipole – dipole configuration-with spacing of 10m length. Resistivity measurements carried out with resistivitimeter GL-4100 GSound type and processed with software Res3Dinv. From the analysis it can be concluded that the entire study area has been contaminated by leachate polution, especially in the surface layer to a depth of 13.9 meters.

The sample of this research is XB as experiment class and XE as control class were drawn by purposive sampling. The study result obtained was analysis with t-test separated varians, and the results showed tcount = 3.78 and ttable = 2.01 in significant standard 5% and released standard 5. Because Ho rejected and Ha accepted. So, we can conclude that contextual teaching and learning model with student worksheets positive influence toward student’s physics study result at SMA Attohiriyah Bodak academic year 2015/2016

Abstract

This study aims to improve learning outcomes and critical thinking skills of students MAN 1 Mataram Academic Year 2012/2013 through the application of cooperative learning model and strategy learning POE (Predict Observe Explain). The type of research used is classroom action research (PTK). This study was conducted in two cycles. Each cycle consists of planning, execution, observation, and reflection. Data on cognitive learning outcomes was obtained from PG tests and critical thinking through LKS. The subjects of the study are students of class X-1 that is 35 people. The results showed that, there is an increase in learning outcomes and students' critical thinking skills after the application of learning models. In the first cycle of classical completeness of cognitive learning results of 48.39%, the second cycle increased to 87.88%. The students' critical thinking ability in the first cycle was 67.28, and the Ikedua cycle increased to 74.62 with critical criteria. It can be concluded that cooperative learning model with POE (Predict Observe Explain) learning strategy has improved yield learning and critical thinking skills of students.

Abstract

This research aims to make prototype battery from star fruit as alternative energy. In everyday life electrical energy used comes from fossils that will be used up in a period of time. Therefore, it takes an alternative energy that can reduce the use of non-renewable energy. We utilize star fruit vegetable as an alternative energy used as a replacement battery, where the battery can be used as energy. Battery of star fruit has a power of 1 Volt and almost equivalent to the battery in the market that is 1.5 V voltages.

Abstract

This research aims to enhance students’ critical thinking skills of SMP Islam Abhariyah on the academic year 2015/2016 through the application of the generative learning model. Research method used was classroom action research (PTK). This research was conducted in two cycles. Each cycle consist of planning, implementating, observating, and reflecting. Data learning activities of the students and teachers’ activities obtained by observation, while data on students’ critical thinking skills test was obtained by an evaluation at the end of each cycle. The subject of this study was 28 students in VIII-B class. Application of the generative learning model in this study considered as successful if the value of critical thinking skills of the students at a minimum categorized as critical. The data for student’s critical thinking skills was accomplished by using an essay test, and the average value of students is 41.96 (categorized very less critical) whit classical completeness achieved only 3,57% in the cycle I and in the cycle II showed the average value of the students is 68,92 (categorized critical) whit classical completeness increased to 85,71%. Research data of student’s activities was taken by using the student’s observation sheet. The average score in the cycle I is 46.50 (categorized as fairly active) and in the cycle II is 66.00 (categorized as active). The data of teacher’s activities was taken by using teacher’s observation sheet. The presentation of learning material is 64,28% (categorized as good) in the cycle I and 91,06% (categorized as very good) in the gathering II. Thus, the conclusion to this study is the application of the generative learning model can improve students’ critical thinking skills.

Abstract

[Title: Manufacture of Gold (Au) Capture Filters Using Chitin and Chitosan from Crab Shells]. This study aims to analyze the ratio of absorption capacity between chitin, chitosan and chitin-chitosan mixture from crab shells as a Gold catcher filter (Au). The preparation of chitin and chitosan from crab shells begins with demineralization using 1.5 M HCl, deproteination using 3.5% NaOH and deacetylation using 60% HCl. Chitosan that formed characterized and analyz ed its ability to absorb gold using AAS (Atomic Absorbsion Spectroscopy). The result of analysis using AAS showed that chitin was able to absorb 67.76%, chitin-chitosan mixture 83.57% and chitosan 87.82%. The result showed that chitosan had better absorption percentage to Gold (Au).
