Abstract

Penelitian ini bertujuan untuk mengembangkan media pembelajaran interaktif berbasis web dalam mata kuliah sejarah dan kepustakaan kimia berdasarkan penilaian teman sejawat (dosen) dan mahasiswa sebagai pengguna serta pengaruhnya terhadap motivasi belajar mahasiswa. Penelitian ini didesain sebagai penelitian pengembangan model prosedural. Instrumen yang digunakan lembar penilaian kualitas media dan angket motivasi. Aspek yang dinilai meliputi kemudahan navigasi, pengetahuan dan presentasi informasi, integrasi media, estetika media, serta fungsi media secara keseluruhan. Data hasil penelitian dianalisis secara deskriptif kuantitatif. Berdasarkan hasil penilaian oleh dua dosen Jurusan Pendidikan Kimia dan 36 mahasiswa. Hasinya menunjukkan bahwa media pembelajaran yang dikembangkan berkualitas sangat baik. Terdapat beberapa perbedaan hasil penilaian dari kedua subjek penilai jika ditinjau dari setiap aspek dan indikator penilaian. Pembelajaran dengan menggunakan media interaktif berbasis web mampu meningkatkan motivasi belajar mahasiswa sebesar 3,5%.

Abstract

In recent years, the uses of Multimedia Based Learning (MBL) in classroom instruction increased widely. Overall, this implementation aims to improve students’ motivation and also their learning outcomes. This study was answering the effect of MBL toward students’ Self-Regulated Learning (SRL) in chemistry teaching and learning. The experiment was conducted in class XI of senior high school in Yogyakarta. Researchers create some computer based media for chemistry materials and continued with expert judgement of the media. Students’ data SRL were measured using validated questionnaire. The questionnaire consists of three components, i.e. metacognitive, motivation and behavior. The results showed that there was significant differences in SRL of students before and after participating in chemistry teaching and learning which applying MBL.

Abstract

Tujuan penelitian ini adalah mengetahui pengaruh pH pada adsorpsi kation unsur hara Ca2+ dan K+ silika lumpur lapindo hasil pemisahan. Data dikumpulkan melalui eksperimen adsorpsi, dimana 3 gram silika hasil pemisahan lumpur Lapindo dilarutkan dalam 300 mL larutan yang berisi Ca2+ atau K+ 0,0001 M atau 0,001 M, dan diaduk selama waktu kesetim- bangan, yaitu 2 jam. pH suspensi divariasi dan dibiarkan 2 jam, sampel diambil dan diukur konsentrasi kation bebas dalam larutan dengan Atomic Absorption Spectrophotometry un- tuk Ca2+  dan Flame Atomic Emission Spectroscopy untuk K+. Variasi pH dilakukan dari 3 hingga 10 dengan suhu dan waktu kontak dipertahankan 30 oC dan 2 jam. Hasil penelitian menunjukkan kedua kation tersebut terikat dengan pola sigmoid, membesar seiring dengan meningkatnya harga pH. Pada semua harga pH yang teramati, Ca2+dan K+. terikat dalam jumlah yang tidak berbeda secara signifikan. Sorben silika dalam air membentuk silanol (SiOH) yang terprotonasi pada pH rendah, membentuk SiOH + dan terdeprotonasi pada pH tinggi menjadi SiO¯ . Baik Ca2+ maupun K+. diikat melalui reaksi pertukaran kation dimana Ca2+  atau K+. menggantikan proton H+ dari gugus -OH silanol membentuk [SiO(CaOH)] untuk Ca2+, dan [SiO-K] untuk K+.Kata kunci: adsorpsi;Ca2+; K+.; pH; silika

Abstract

Purification of silica sand volcanic Mount Merapi has been done, for raw material photovoltaic. Leaching purification process is done using aqua regia solution, H2SO4, and HCl. Purification of silica sand of Mount Merapi as a raw material photovoltaic assumes that photovoltaic technologies that utilize solar energy is quite affordable, do not run out, and clean so that it will provide long term benefits are substantial. Stage purification process through grinding up to size 60 mesh, iron using magnetic separation, leaching of acid and alkaline leaching. Characterization of the samples using XRD and XRF. The result showed that Mount Merapi volcanic sand containing silica is high at 48-50%. XRD characterization results indicate that the silica in sand samples well as silicon dioxide or mineral has amorphous structure. Among aqua regia, H2SO4 and HCl leaching that has the ability to nicest namely the concentration of concentrated HCl and purified silica has a purity of 59%. Keywords: purification, silica, volcano sand

Abstract

Students have difficulties in relating the chemistry phenomena they learned and the life around them. It is necessary to have teaching aids which can help them to relate between chemistry with the phenomena occurred in everyday life, which is chemistry’s teaching aids based on local wisdom. There are 3 teaching aids which used in chemistry teaching and learning, i.e. clay molymod, electrolyte tester, electroplating tool. The chemistry teaching aids was reviewed by media experts, material experts, and also reviewers. The reviewers’ assessment showed that all of the teaching aids have a very good quality. Based on the response from Senior High School’ students, they all agree that the teaching learning process using the teaching aids could improve their learning motivations.
