Abstract

The energy crisis is one of the major problems facing the world today, especially electrical energy. Supercapacitors are an alternative solution as an electrical energy storage divais. In this study, batik kawangkoan peanut shell samples have been successfully modified into activated carbon as a supercapacitor electrode. The carbonization process is given a carbonization temperature treatment of 350oC, 400oC, 450oC, 500oC, 550oC which is activated using a 7 M KOH solution by heating in a furnace at 750oC to produce a voltage of 0.966 V, 1.273 V, respectively, 1.295 V, 1.325 V, 1.654 V and currents of 18.56 mA, 23.43 mA, 26.47 mA, 30.53 mA, 48.24 mA which shows that there is a change in the value of current and voltage in supercapacitors, and the best sample is in the sample with 550oC carbonization temperature treatment. Thus, it can be concluded that carbonization temperature has an influence on the current and voltage characteristics of supercapacitor electrodes.

Abstract

Penelitian ini bertujuan untuk mengetahui kesulitan yang dialami siswa dalam menyelesaikan soal fisika pada materi hukum archimedes berdasarkan model polya. Jenis penelitian ini adalah penelitian deskriptif kualitatif. Penelitian ini dilaksanakan di SMA NEGERI 1 TOMBATU. Subjek dalam penelitian ini adalah 25 siswa kelas XI A 1 kemudian diambil 3 siswa untuk sampel wawancara yang terdiri dari 1 siswa berkemampuan baik, 1 siswa berkemampuan cukup dan 1 siswa berkemampuan kurang. Teknik pengumpulan data yang digunakan melibatkan tes yang kemudian dianalisis berdasarkan tahap-tahap model polya yaitu Memahami masalah, Merencanakan pemecahan permasalahan, Melaksanakan rencana pemecahan masalah dan Memeriksa kembali kemudian dilakukan wawancara pada 3 orang siswa yang menjadi subjek penelitian. Analisis data melalui tahap reduksi data, penyajian data, dan penarikan kesimpulan. Hasil penelitian menunjukkan bahwa pada tahap memahami masalah seluruh siswa mampu memahami masalah dengan baik, yaitu dengan menuliskan diketahui dan ditanyakan pada soal dengan benar dan tepat. Pada tahap merencanakan pemecahan permasalahan semua siswa mampu menuliskan dan menentukan persamaan yang digunakan dengan baik dan benar. Pada tahap melaksanakan rencana pemecahan masalah dan memeriksa kembali ada beberapa siswa yang mengalami kesulitan

Abstract

The study is conducted with the ability to representation in understanding the concept of interference and diffraction. The purpose of this research is to map the ability of student representation. The types of representations used in this research are verbal representation, visual representation, and mathematical representation. Research is conducted using analytic descriptive methods. The study was conducted in the Manado state university physics department during the V semester of the 21-student physics education course. The data-gathering techniques use essays which consist of verbal, visual, and math. By research, it was found that the ability to the student was divided into three categories that were the singular representation category, the dual representation category, and the complex representation category. Data analysis shows a 9.5% for single representational ability category, 47.6 % category double representational ability, and 42.9% category complex representational ability. Therefore, a student's dual capacity of representation is more dominant than a single representation and complex representation

Abstract

Activation of rattan charcoal is carried out to increase pore size and formfunctional groups. In this study, activated carbon from rattan has been made withdifferent activation times. The research objective was to determine the pore size andfunctional groups contained in the activated carbon of rattan with an activation time of 5hours and 10 hours. The solution used to activate rattan activated carbon is KOH 10 mlcharcoal 10 grams with a burning temperature of 1500C. The results of rattan activatedcarbon were characterized using SEM and FTIR to see the pore size and functionalgroups. The activated carbon sample of rattan with the activation time of 5 hours had apore size that was not too large and only a few were formed and the sample of 10 hoursof activation time had a large pore size. The samples for 5 hours and 10 hours ofactivation have the same functional groups, namely O-H, C-C, C-O, C-H.

Abstract

Model of Model-Based Instruction (MOMBI) is a learning model that emphasizes the formation of mental models through the stages of provocation, preconcept, presentation, scaffolding, and practice. The aim of this research is to determine the use of MOMBI in improving students’ learning results in Newton's Second Law material at SMA Negeri 1 Amurang. The method used in this research was quasi-experimental method with a pretest-posttest control group design. The sample for this study was taken randomly with XI-H students as the experimental class with MOMBI treatment and XI-I students as the control class. Data was collected using essay tests and observation. The data obtained was then analyzed statistically. Based on the average results of the pretest and posttest for the control class, the average pretest value was 39.44 and the average posttest value was 56.67. A higher increase was obtained in the experimental class with an average pretest score of 41.67 and an average posttest score of 78.89. So it can be concluded that the Model of Model-Based Instruction can improve student’s learning results in Newton's Second Law at SMA Negeri 1 Amurang
