Abstract

The development of science and technology is inevitable, therefore innovation is needed in every aspect of education to keep up with technological advances, as well as conservation education. This research was conducted with the aim of exploring the environmental service potential of Mount Ciremai National Park (TNGC) by developing a TNGC conservation education website. The TNGC conservation education website to support environmental awareness was developed using the Research and Development (RD) research method. Using the Four-D model which is carried out until the disseminate stage. At the design stage, the Multimedia Development Life Cycle (MDLC) method was used because the TNGC conservation education website is a multimedia product. Based on the results of the material and media expert test assessment, the TNGC conservation education website to support environmental awareness received an average score of 81.89, which means it falls into the feasible category. These results are obtained based on the results of data processing for material aspects of 81.47; and media aspects of 82.31. The development of this website media is expected to be one of the alternative learning resources for sustainable conservation education, especially within the Department of Biology and generally for the wider community.

Abstract

Learning is limited and not maximized in the use of technology in every school. In addition, learning that is still focused on the teacher as a learning resource, causes students to be less critical in understanding the existing problems, so that technology is needed, with the application of socio-scientific issue-based E-modules. The purpose of this study is to determine the effect of implementing E-modules based on socio-scientific issues in improving students' critical thinking skills. The method used in this research is quantitative research with a quasi-experimental approach. The research design used a pretest-posttest control group design, with class X MIPA 1 as the experimental class and class X MIPA 4 as the control class. The results showed that there was an increase in students' critical thinking skills in the experimental class which was higher than the control class with the average difference between the pretest and posttest results in the control class. This increase can be seen from the statistical paired samples as significant output. The results of the student response questionnaire showed a good category. The conclusion in this study is that the application of E-modules using android appy pie based on socio-scientific issues has an effect on increasing students' critical thinking skills.

Abstract

The purpose of this study was to describe student learning activities, to analyze the differences in increasing scientific literacy in the aspect of student competency and to analyze the increase in conservation attitudes of class X students in plantae material which was taught using the Natural Surroundings (JAS) approach assisted by the QR Code. This research is a quantitative study with a sample of 31 students of class X MIPA 1 control class and 32 students of class X MIPA 3 experimental class. The research design used was the pretest posttest control group model. Data collection techniques in this study used observation, tests and questionnaires. The results showed that there was an increase in student learning activities at each meeting. There is a significant difference in increasing scientific literacy in the competency aspect in indicator 2 with a significance value of 0.000. And there is an increase in conservation attitudes after the learning treatment. Based on the results of the study it can be concluded that the application of learning using the Natural Surrounding Exploration (JAS) approach assisted by the QR Code can increase student learning activities, scientific literacy aspects of competence and students' conservation attitudes towards biology learning.ABSTRAK: Tujuan dalam penelitian ini yaitu untuk mendeskripsikan aktivitas belajar siswa, untuk menganalisis perbedaan peningkatan literasi sains aspek kompetensi siswa dan untuk menganalisis peningkatan sikap konservasi siswa kelas X pada materi plantae yang diajarkan dengan pendekatan Jelajah Alam Sekitar (JAS) berbantuan QR Code.

Abstract

The Gunung Kuda mining area in the Cipanas Village area, Dukupuntang District, Kuningan Regency has the potential for natural resources as a type of C excavation mine with a limestone soil texture where the results are partly used as raw materials for cement, natural stone and ceramics. The aim of this research is to examine the impact of Gunung Kuda mining activities on environmental quality as a source of SDGs-based science learning. The research method used is descriptive qualitative. Data collection techniques were carried out using open interviews, field observations and literature reviews. The results obtained show that Mount Kuda mining activities have positive and negative impacts. The positive impact felt by the surrounding community is as a center of livelihood to stabilize the economy. However, there are also negative impacts in the form of decreasing the quality of the surrounding environment, such as the river in the Gunung Kuda mining area which is classified as moderately polluted, namely with a value of Plj 10.39; air pollution in the form of dust resulting from the breakdown of rocks; as well as reduced vegetation in mining areas. Efforts made by the management and surrounding communities to balance the environment in the mining area are by replanting trees that have been reduced due to the mining process with trees that are considered to have benefits such as mango trees, durian trees and sengon trees. The results of the analysis of the impact of Mount Kuda mining on environmental quality are suitable as a study in SDGs-based contextual science learning resources.
