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.

This research is a descriptive study with a qualitative approach, which aims to describe the ability of junior high school students to solve physics problems in various forms of problem representation. The subjects in this study were the IX grade junior high school students in six Palu city schools. Respondents for interviews in the study amounted to 4 people for each form of problem representation, with the criteria of students who answered right, students who answered ± 50% correct, students who answered incorrectly, and who did not answer. The instrument used was a test of problem solving skills and interviews. The data obtained were analyzed qualitatively including data reduction, presenting data and verification while descriptive analysis was performed by calculating the total score, calculating the percentage and categorizing problem solving abilities. The results obtained by the average ability of junior high school students to solve physics problems in various forms of problem representation 21.86% (less category), with the percentage of each form of representation ie verbal representation 36.09% (less category), image/picture representation 23.78% (less category), diagram representation 19.47% (poor category) and graphic representation 8.10% (poor category).

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.

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.
