Abstract

Saat ini, penggunaan gadget seperti handphone, laptop, notebook, tablet, dan lainnya merebak pada siswa usia sekolah dasar ataupun sekolah menengah. Ketergantungan ini dapat menimbulkan dampak ketidakpedulian siswa dengan lingkungan sekitar. Tujuan penelitian ini adalah untuk mengembangkan dan menganalisis kepraktisan serta keefektifan panduan pembelajaran outdoor bermuatan karakter peduli lingkungan pada materi ekologi. Penelitian ini menggunakan langkah penelitian dan pengembangan (R&D). Subjek penelitian adalah kelas X SMA Kesatrian 2 Semarang. Hasil penelitian menunjukkan bahwa panduan pembelajaran outdoor dinyatakan efektif karena dapat menanamkan karakter peduli lingkungan dan dapat meningkatkan hasil belajar kognitif, afektif, dan psikomotor pada siswa. Karakter kepedulian lingkungan kelas eksperimen berada pada kategori baik dan sangat baik. Ada perbedaan secara signifikan, nilai rata-rata hasil belajar kognitif kelas eksperimen sebelum dan sesudah pembelajaran. Rata-rata persentase hasil belajar afektif siswa berbeda secara signifikan antara kelas eksperimen dengan kelas kontrol. Rata-rata persentase hasil belajar psikomotor siswa berbeda secara signifikan antara kelas eksperimen dengan kelas kontrol.   Nowdays, the use of gadgets such as mobile phones, laptops, notebooks, and tabletshas widely used by both elementary and high school students. This interdependence could create limited students’awareness to environmental issues. The purpose of this research was to develop and analyze the simplicity and the effectiveness of the outdoor learning guide book on Ecology, developed on the basis of environmentalcharacter inculcation. Research and development was implemented to develop this book.Subjects of study wasKesatrian 2 high schoolclass X student. Research findings showed that the outdoor learning guidance was verified‘effective’ because the use of it effected students character of environmental awareness andstudent learning achievements in cognitive, affective, and psychomotor domain. Character of environmental awareness from class experiment was verified‘good and excellent’.There was significant difference between the average score of pretest and posttest from experiment and control classes. The average percentage of students' affective learning achievement differed significantly between the experiment and control classes. The average percentage of students’ psychomotor learning achievement differed significantly between the experiment and control classes.

Abstract

Research on the use of Chorella sp. on reducing of Zn concentrations was conducted in order to know Zn concentration which is maximally absorbed by Chorella sp. In the preliminary experiment, there was the range of Zn concentration that caused the highest population growth of Chorella sp. was 0.1 – 0.4 ppm. In the main experiment, it was divided into five concentrations and one control with three replications. Each of concentrations was treated on Chorella sp. culture with the first Zn concentration (0.0042 ppm) in the medium culture. Those concentrations were 0.05 ppm, 0.15 ppm, 0.35 ppm, 0.45 ppm. All of the concentrations were given on the day of 5. The density of cells which was used for each flask was 100,000 cells/ml. The fertilizers used for each flask were : ZA, Urea, TSP, FeCl3, EDTA. The result showed that there was an interaction between the population growth of Chorella sp. and the reducing of Zn concentration. The highest population growth of Chorella sp. was found in the treatment of 0.15 ppm Zn concentration.

Abstract

This research aims to increase students' activeness and critical thinking abilities in biology subjects through the application of the Problem Based Learning learning model. The background is that students are very passive when learning activities take place and their skills in asking and answering questions are still limited to memory and understanding. This type of research is Classroom Action Research (PTK) which is carried out in three cycles. The data collection techniques used are test and non-test techniques. Data analysis techniques use descriptive and quantitative analysis. The research subjects were 31 students consisting of 12 male students and 19 female students. The research results showed an increase in students' activeness and critical thinking. The percentage of active students increased in cycle I to 51.7%, then increased in cycle II to 55.7% and increased in cycle III to 59.5% of active students. Increased critical thinking skills can also be seen through PBL learning with pre-test and post-test scores increasing in each cycle. In cycle I the average pre test score was 36.4, then it increased in cycle II to 45.1, and in cycle III it was 59.6, the pre test of the three cycles was still below the KKM. The average post test score in cycle I was 60.6, then increased in cycle II to 75.4, and in cycle III 84.1, post test in cycle I was still below the KKM, while in cycles II and III it had exceeded the KKM.
