Abstract

This research is motivated by the influence of high technology on education; hence educators need to choose the right technology device to use and compare student learning interests with and without the support of computer and android multimedia.  It was quasi-experiment research with posttest only and non-equivalent control group designs.  The subjects of this research were the eleventh-grade students of Natural Science. There were 2 sample classes—the eleventh-grade students of Natural Science 3 (experiment I) taught using computer multimedia, and the students of Natural Science 1 (experiment II) taught using android multimedia. Interview with teachers, preliminary data test that was homogeneity test, final data test, learning interest questionnaire, interview, observation, and documentation were used to collect the data. The analysis result showed that the learning interest percentage of experiment I was 73.88% with the high category, and experiment II was 81.19% with the very high category.  An independent t-test was used to see whether there was a significant difference between experiments I and II. It showed a significant difference in chemistry learning interest between students taught by using computer-based multimedia and those taught by using android-based multimedia on the acid-based lesson of chemistry subject at the eleventh grade of Natural Science.  Therefore, Android-based learning could be developed in the learning process to support student chemistry learning interests.REFERENCESAnugraheni, P.

Abstract

AbstractBilions of new inorganic compounds and many synthetic methods has discovered for decades based on many reason. Its wider use makes inorganic compounds continuously synthesized by chemists. However, most of them were not produced in Indonesia. One of the solution was preparing synthesizing inorganic compounds subject matter to preservice chemistry teacher. Nevertheless, because it is not easy to mastered, didactic reduction must be done. The objection of this study was to reconstructed this subject matter using the Model of Educational Reconstruction (MER), start form curriculum analysis, empirical studies, and analysis of content structure. This research was conducted by mixed method exploratory design, with preservice chemistry teacher 6th and 8th semester as the sample. The reconstruction of synthesis inorganic compounds subject matter material was the following sequence of macro propositions: general description of synthesized of inorganic compounds, benefits of the inorganic compounds, reactions that can underlie possible formation of inorganic compounds, the thermodynamics and kinetics of reactions processes the properties of the inorganic compounds, basic synthesis techniques and basic characterization techniques. And the most important thing that must be understood by potential chemists are: material characteristics, molecular structure of compounds, and chemical reaction.Keywords : Model of Educational Reconstruction, synthesis of inorganic compounds, preservice chemistry teacher

Abstract

AbstrakMeningkatnya penggunaan plastik diikuti dengan besarnya kepedulian terhadap isu lingkungan mengenai pembuangan produk plastik sintetis yang sulit terurai. Salah satu alternatif untuk mengatasinya adalah dengan memodifikasi plastik agar bersifat biodegradabel. Plastik biodegradabel (plastik ramah lingkungan) dirancang mampu terdekomposisi di alam. Tingkat di biodegradasi yang terjadi tergantung pada kondisi tanah seperti suhu, kadar air, tingkat aerasi, keasaman dan konsentrasi mikroorganisme sendiri. Berdasarkan hal diatas, maka dilakukan penelitian dengan tujuan mengetahui efektifitas penguraian plastik ramah lingkungan dengan metode pengomposan dalam tanah gambut (TG) dan tanah sampah, serta faktor pH. Dari hasil penelitian kami mendapatkan bahwa pada semua perlakuan uji pada hari ke-20 sampai hari ke-60 terjadi peningkatan persentase penurunan berat plastik ecoplas dan oxium. Sedangkan persentase perubahan berat plastik terbesar dari proses biodegradasi terhadap semua perlakuan uji adalah pada  TG3pada hari ke-60 yaitu 0,45%. Secara umum, jika pH tanah dibuat semakin asam, maka menyebabkan penguraian plastik semakin bertambah.Kata Kunci : Plastik, Mikroorganisme tanah, lahan gambut.
