Penelitian ini bertujuan untuk mengetahui potensi angin di Pantai Blimbingsari Kabupaten Banyuwangi sebagai energi listrik alternatif. Objek penelitian ini harus mengetahui besarnya kecepatan angin dan daya listrik yang dihasilkan di Pantai Blimbingsari. Energi alternatif listrik dapat mengatasi keterbatasan listrik dan membantu penerangan penjual ikan bakar di sekitar pantai Blimbingsari. Metode penelitian yang digunakan yaitu survey dan Aplikasi Zephyrus WindMeter di Smarthphone. Survey dilakukan secara langsung di pantai Blimbingsari pada jam 08.00-16.00 WIB dengan menggunakan Aplikasi Zephyrus WindMeter dalam pengambilan data kecepatan angin. Pengambilan data dilakukan di 5 titik acuan dengan pengukuran sebanyak 3 kali setiap titik acuan. Beberapa kajian literatur jurnal menunjukkan bahwa angin memiliki potensi untuk dijadikan energi alternatif dengan pembuatan pembangkit listrik tenaga angin yang efektif. Berdasarkan perhitungan menunjukkan data hasil bahwa pantai Blimbingsari berpotensi rendah dengan rerata kecepatan maksimal yang terukur 2,5 m/s dan daya yang dihasilkan dari perhitungan 28,7 watt. Sehingga diperlukan alternatif lain yang dirancang untuk mengatasi kecepatan angin yang rendah untuk perancangan Pembangkit listrik.
ABSTRAK Penelitian ini bertujuan untuk membandingkan pemahaman konsep materi fisika model atom yang telah dipelajari sebelumnya berdasarkan tujuh indikator pemahaman konsep Anderson dengan subjek 50 siswa kelas XII MAN 1 Banyuwangi dan 50 siswa kelas XII MAN 3 Banyuwangi. Penelitian ini menggunakan metode survey dengan mengumpulkan dan menganalisis data secara langsung dengan teknik pengumpulan data menggunakan tes pemahaman konsep berupa 14 butir soal yang disusun berdasarkan tujuh indikator pemahaman konsep Anderson yang sebelumnya telah divalidasi oleh validator. Langkah dalam menganalisis data hasil penelitian yaitu dengan menggunakan rumus persentase deskriptif. Hasil penelitian menunjukkan bahwa MAN 3 Banyuwangi unggul dalam nilai rata-rata dengan persentase sebesar 63,3%. Pada 7 indikator pemahaman konsep, MAN 1 Banyuwangi unggul pada indicator Interpretting, Infering, dan Comparing dengan persentase berturut-turut sebesar 33%, 54%, dan 47%. MAN 3 Banyuwangi unggul pada indikator Classifying, Exemplifying, Explaining, dan Summarizing dengan persentase berturut-turut sebesar 61%, 89%, 80%, dan 70%. Hasil penelitian secara keseluruhan menunjukkan rata-rata kategori rendah. Dengan demikian, maka diperlukan upaya yang dapat meningkatkan pemahaman konsep siswa seperti penggunaan media pembelajaran. Kata kunci: Model Atom, Pembelajaran Fisika, Pemahaman Konseptual ABSTRACT This study aims to compare the understanding of the concept of atomic model physics material that has been studied previously based on seven indicators of Anderson's concept understanding with the subject of 50 students of class XII MAN 1 Banyuwangi and 50 students of class XII MAN 3 Banyuwangi. This study uses a survey method by collecting and analyzing data directly with data collection techniques using a concept understanding test in the form of 14 questions that are arranged based on seven indicators of Anderson's concept understanding which have been previously validated by the validator. The step in analyzing the research data is by using the descriptive percentage formula. The results showed that MAN 3 Banyuwangi excels in the average value with a percentage of 63.3%. In 7 indicators of concept understanding, MAN 1 Banyuwangi excels in indicators Interpreting, Inferring, and Comparing with percentages of 33%, 54%, and 47% respectively. MAN 3 Banyuwangi excels in indicators Classifying, Exemplifying, Explaining, and Summarizing with percentages of 61%, 89%, 80%, and 70% respectively. The results of the research as a whole show the average category is low. Thus, efforts are needed that can improve students' understanding of concepts such as the use of learning media.

Relativistic energy is a material that is considered difficult by students because the general solution takes quite a long time. This is based on the results of interviews with students of SMAN Plus Sukowono. The magic number method is a method using the Pythagorean principle through special numbers that are often encountered in relativistic energy problems. The purpose of the research was to obtain data on student responses to the magic number method as an alternative solution to the relativistic kinetic energy problem that makes it easier for students to solve relativistic energy problems. The research method used by the researcher is the survey research method with descriptive analysis. The respondents used were 28 students of class XI MIPA SMAN Plus Sukowono and used an assessment instrument in the form of a response questionnaire. Student response questionnaires were compiled based on Stellen M. Chafe's theory which was based on the cognitive, affective, and conative dimensions. The results of the research on student responses to the magic number method as an alternative solution to the problem of solving relativistic kinetic energy problems obtained percentage data on the cognitive dimension of 72.93% in the positive category, the affective dimension of 80.63% in the very positive category and the cognitive dimension in 75% in the positive category. The average of the overall response dimensions is 76.19% in the positive category. This research can be concluded that the magic number method can be used in physics learning the theory of relativity.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
