Abstract

This study aims to develop fun science teaching material on the energy transformation to promote scientific literacy of junior high school students. The research is a four-D design of Research and Development. The validity of designed teaching materials had been determined by experts and science teachers. Scientific literacy achievements and student’s responds were obtained using scientific literacy test and questionnaire on 95 students. Data analysis was carried out in a quantitative descriptive. The result of this study shows the fun science design contains the concepts of energy transformation that are presented contextually in form of comics strip and science songs, the validity score from experts and teachers were 87.5% and 93.5% respectively, N-gain of 62%, and most of students agree with the use of fun science teaching materials. Thus, fun science teaching material can be used in science learning to promote scientific literacy.

Abstract

ABSTRAKTanaman sirih (Piper betle L) merupakan jenis tanaman yang tumbuh merambat dengan ketinggian mencapai 5-15 m. Tanaman ini sebagai tanaman obat yang berkhasiat untuk penyembuhan terhadap penyakit kulit yang disebabkan oleh bakteri Staphylococcus aureus karena memiliki daya antiseptik yang baik. Bagian tanaman yang digunakan yaitu daunnya karena banyak mengandung senyawa turunan fenol. Penelitian ini bertujuan untuk mengetahui efek antibakteri ekstrak daun sirih (Piper betle L) dan untuk mengetahui konsentrasi ekstrak daun sirih yang memiliki efek antibakteri paling efektif terhadap bakteri Staphylococcus aureus penyebab penyakit kulit. Metode yang digunakan adalah metode eksperimen dengan rancangan percobaan Rancangan Acak Lengkap (RAL) dengan menggunakan 2 metode yaitu  metode Refluks dan Maserasi dengan masing-masing konsentrasi ekstrak daun sirih (Piper betle L) yang terdiri atas satu faktor yaitu konsentrasi ekstrak daun sirih (Piper betle L) dengan taraf faktor 0%, 5%, 10%, 15%, 20% dan 25%. Variabel respon yang diamati adalah luas zona hambat bakteri Staphylococcus aureus. Hasil penelitian menunjukkan bahwa pada ekstrak daun sirih terdapat senyawa antibakteri yang efektif dalam menghambat bakteri Staphylococcus aureus. Zona hambat mulai terlihat pada konsentrasi 5%. Perlakuan dengan cara maserasi, pada konsentrasi 10% dan 20% zona hambat tidak berbeda nyata, sedangkan pada konsentrasi 15% dan konsentrasi 25% zona hambat yang dihasilkan berbeda nyata dengan semua konsentrasi yang digunakan. Perlakuan dengan cara refluks, pada konsentrasi 10% dan 25% zona hambat tidak berbeda nyata, sedangkan pada konsentrasi 15% dan konsentrasi 20% zona hambat yang dihasilkan berbeda nyata dengan semua konsentrasi yang digunakan. Dengan demikian, diperoleh konsentrasi ekstrak daun sirih yang memiliki efek antibakteri yang paling efektif yaitu pada konsentrasi 25% dengan cara maserasi, sedangkan cara refluks yaitu pada konsentrasi 20%. Kata kunci : Sirih (Piper betle L), Staphylococcus aureus ATCC 25923, antibakteri, rancangan acak lengkap (RAL)

Abstract

Teacher work productivity can affect the progress of the quality of learning in schools. From the initial survey, it is seen that the work productivity of teachers, especially private junior high school teachers, has not been as expected, meaning "das sein" has not been like "das sollen". Therefore, the teacher's work productivity is interesting to be studied. The research aims to find an effort to increase teacher work productivity by examining the relationship between other variables with teacher work productivity. The other variables are commitment to the profession and supervision of the principal. This research was conducted using the correlational statistical method to find out whether commitment to the profession and supervision of the principal has a positive relationship with teacher work productivity. Based on these results, an analysis was then performed using the Sitorem Method to establish recommendations and find a priority order for improvement of the indicators of the research variables needed. The study was conducted on private junior high school teachers in Klapanunggal District, Bogor Regency with a population of 134 teachers, with a proportional random sample of 100 teachers. The results showed that there was a positive relationship between commitment to the profession with teacher work productivity with a correlation coefficient of 0.512, there was a positive relationship between the supervision of principals with teacher work productivity with a correlation coefficient of 0.464, and there was a positive relationship between commitment to the profession and supervision of principals as together with teacher work productivity with a correlation coefficient of 0.676. This shows that teacher work productivity can be increased through strengthening commitment to the profession and supervision of the principal. The results of Sitorem's analysis show that strengthening commitment to the profession and supervision of school principals can be done by improving indicators that are still weak and maintaining good indicators. Indicators that are still weak and require improvement in the order of priority handling are as follows: 1. Professional development efforts, 2. Services to students, 3. Guidelines for student success, 4. Responsibility, 5. Love of the profession, 6. Provision of feedback from results supervision, 7. follow up supervision, 8. Continuity of supervision, 9. Provision of assistance and guidance, 10. Interaction in supervision, 11. Speed of completing work, 12. Personal development, 13. Positive contribution to the environment, 14. Targets to be achieved , and 15. Relationships with fellow teachers. Whereas the 3 indicators that are in good condition and remain to be maintained are: 1. Obedience to the rules, 2. Quality of work, and 3. Compliance with work

Abstract

Literasi sains siswa Indonesia masih rendah dan buku yang selama ini digunakan belum melatih siswa untuk memahami hakekat sains. Oleh karena itu, literasi sains siswa perlu ditingkatkan melalui bahan ajar yang menyajikan fenomena alam dan permasalahan yang terjadi di sekitar siswa. Tujuan penelitian adalah mengembangkan bahan ajar bermuatan konteks kelautan untuk meningkatkan literasi sains siswa. Penelitian ini merupakan pengembangan dengan metode four step material teaching development. Efektivitas bahan ajar bermuatan konteks kelautan terhadap peningkatan literasi sains siswa dilakukan melalui pretest dan posttest literasi sains kepada 30 siswa kelas VII SMP Agribinta Kabupaten Cianjur. Pengumpulan data menggunakan: 1) lembar validasi ahli untuk menentukan kelayakan bahan ajar; 2) tes keterpahaman untuk menentukan pemahaman siswa terhadap bahan ajar; 3) tes literasi sains untuk menentukan literasi sains siswa, dan 4) angket untuk menjaring sikap siswa terhadap bahan ajar. Data yang diperoleh selanjutnya dianalisis secara deskriptif kuantitatif. Data pretest dan posttest dihitung N-gain kemudian dikategorisasikan. Hasil penelitian menunjukkan: 1) hasil validasi ahli diperoleh nilai rata-rata 3,85, 2) bahan ajar bermuatan konteks kelautan dapat meningkatkan literasi sains siswa dengan rata-rata hasil pretest sebesar 32,00; posttest sebesar 60,70; N-gain sebesar 42,11% (kategori sedang), serta 3) sikap sains siswa termasuk kategori tinggi.

Abstract

The research objective was to improve the understanding and creative thinking skills of elementary teacher as prospective teachers in following science courses. The research design used is to make elementary teacher groups into small groups. During the learning process, observations about elementary teacher cooperation during learning with multimedia media were carried out to assess their understanding and creative thinking skills. The results of the observations of each cycle were evaluated as material for reflection in the next cycle to improve college student understanding and creative thinking skills in accordance with predetermined targets. Data analysis was carried out by descriptive quantitative. From the results of the T-test, the results, it was found that there were significant differences. This means that understanding of science process concepts and skills increases after prospective student teachers experience the learning process using multimedia. From the results of the average value of understanding the concept, increasing from 39.86%  to 88.22%. and science process skills increased the average value from 49.89% to 86.44%. 92% of college student gave a positive response, namely agreeing and strongly agreeing that the science lecture process using multimedia learning media can improve science process skills and understanding of material in science subjects for elementary teacher education college student. Keywords: multimedia; comprehension ability; creative thinking skills.
