The Research about Synthesis and Characterization of SiO2 have been worked. We have synthesized Silica from âpetungâbamboo leaf ash as SiO2 source. This step used sol gel methode. SiO2 were characterized by Fourier Transform Infra Red (FTIR) to investigated the stucture andX-Ray Diffaction to know about structure and crystallinity. FTIR spectra show peak at 617,22 cm-1 area that spesific for Si-H bond, peak at 786,96 cm-1and 1095,57 cm-1 area specific for Si-O-Si bonds. Difractogram of SiO2 show that there are peak at 2Î¸ 21,99; 31,67 and 38,88 were specific for SiO2 that calcinated at 800oC, while for SiO2 that calcinated at 400oC there were no peak at 2Î¸ 31,67 dan 38,88. That peaks not shown may be because low crystallinity of SiO2 that calcinated at 400oC. Calcination temperature greatly affects the crystallinity of SiO2.Â©2017 JNSMR UIN Walisongo.

In addition to literacy education of the Qur'an, coastal communities who work as fish seekers on average also need to be equipped with skills (life skill). Through education and training, coastal communities will have two advantages at once, first able to study the Qur'an quickly, rightly and correctly, and both gain knowledge about fish waste processing. Devotion is done also provide life skill education (life skills) such as processing pellets / feed from fish waste. Supply provided is not limited to the training course but also helps in the management of production permits and feasibility of processing the pellet, and find opportunities in marketing the processed products.

As chemistry teacher candidates, chemistry education students should have a complete mental model, including alcohol. But in reality, 42% of prospective chemistry teacher students at one of the state universities found that alcohol material was difficult to understand. These difficulties are indicators of the lack of mental models of the chemistry teacher candidates. This study aims to explore the types of mental models of prospective chemistry teachers on alcohol material. This research is a type of descriptive research with a qualitative approach. The subjects of this study were students of the Department of Chemistry Education in 2016. The sample was selected using a purposive sampling technique. The number of samples determined was 12 students with different levels of understanding. Mental model excavations were performed using the Diagnostic Test Mental-Interview About Event (TDM-IAE). The diagnostic test consists of open-ended questions, drawing submicroscopic representation activities, and interviews. The results showed that in general chemistry teacher candidates had a synthetic mental model with a percentage of 66.66% verbal description answers. In the picture answers, all chemistry teacher candidates have a synthetic mental model.

Rendahnya hasil belajar peserta didik pada materi hidrolisis khususnya pada level mikroskopik dan proses pembelajaran yang masih menggunakan metode pembelajaran konvensional di MA Uswatun Hasanah, sehingga dilakukan penelitian ini. Model POGIL (Process Oriented Guided Inquiry Learning) bermuatan Multiple Level Representation diharapkan dapat mengetahui tingkat penguasaan konsep dan retensi peserta didik MA Uswatun Hasanah pada materi hidrolisis. Metode: Penelitian ini menggunakan satu sampel untuk memperoleh data penelitian yaitu kelas XI jurusan IPA. Data penelitian diperoleh dengan metode dokumentasi untuk mendapatkan daftar nama-nama peserta didik kelas XI jurusan IPA MA Uswatun Hasanah dan metode tes untuk memperoleh data hasil belajar peserta didik yang diperoleh dari nilai pretest, posttest, dan retest. Hasil penelitian : Penelitian ini menunjukkan bahwa pembelajaran melalui model POGIL bermuatan Multiple Level Representation dapat meningkatkan tingkat penguasaan konsep dan retensi peserta didik kelas XI IPA MA Uswatun Hasanah. Terdapat 30% peserta didik mengalami peningkatan penguasaan konsep kategori tinggi, 40% peserta didik mengalami peningkatan penguasaan konsep kategori sedang, dan 30% mengalami peningkatan penguasaan konsep kategori rendah. Adapun tingkat retensi peserta kelas XI IPA MA Uswatun Hasanah adalah 92,7% yang tergolong tinggi. Berdasarkan hasil penelitian yang telah dilakukan, dapat disimpulkan bahwa Pembelajaran dengan menggunakan model POGIL bermuatan Multiple Level Representation dapat meningkatkan tingkat penguasaan konsep dan retensi peserta didik kelas XI IPA MA Uswatun Hasanah.

Bentonit alam yang telah dimodifikasi menjadi organobentonit dengan menggunakan surfaktakan kationik Benzalkonium Klorida sebagai agen penginterkalasi dengan berbagai variasi suhu. Material hasil sintesis diaplikasikan sebagai adsorben untuk penyerapan logam berat berupa ion logam Zn2+. Proses adsorpsi dilakukan dalam berbagai variasi kondisi yaitu pH dan waktu kontak. Hasil analisis XRD menunjukkan material bentonit yang telah dimodifikasi berhasil di sintesis, hal ini terlihat dari jarak antar lapis pada suhu 50?C sebesar 15,06 Å, suhu 60?C sebesar 16,76 Å dan suhu 70 ?C sebesar 16,50 Å dibandingkan dengan bentonit alam sebesar 12,09 Å. Spektra FTIR menunjukkan serapan pita 2360 cm-1 yaitu adanya vibrasi C-N dan 1465 cm-1 adanya vibrasi N-H. Hal ini menunjukkan adanya garam ammonium kuartener yang di pada interlayer bentonit. Penentuan pH optimum dan waktu kontak pada saat adsorpsi. Dari pH 4-8 menunjukkan bahwa pH optimum untuk proses adsorpsi ion logam Zn2+ adalah pH 6 dengan daya adsorpsi sebesar 99,914%, sedangkan pada bentonit alam sebesar 92,94%, kemudian untuk waktu kontak adalah di 60-120 menit dengan daya adsorpsi sebesar 97,92% pada suhu sintesis 60?C serta waktu kontak untuk bentonit alam 85,31%. Data kinetika adsorpsi menggunakan model pseudo second order lebih sesuai untuk menjelaskan proses adsorpsi ion logam Zn2+. Hal ini dapat disimpulkan bahwa bentonit yang telah dimodifikasi memiliki daya adsorpsi ion logam Zn2+ yang lebih besar di bandingkan dengan bentonit yang belum termodifikasi.

Galvanization is a metal coating process that is widely used in industry. The effects of this metal coating process are not entirely beneficial to society. The issue of pollution generated by the metal coating activity becomes very important. The objective of this research is to reduce Fe metal content from solid waste steel using electrolysis process with variation of pH of electrolyte solution and voltage. This research uses experimental method with test of metal content composition using X-Ray Flouresence, and Fe metal reduction using electrolysis process. This research activity used stainless steel plate as cathode and solid steel waste chunk as anode. Variations of pH of FeSO4.7H2O electrolyte solution used during electrolysis process are pH = 2, pH = 2.5, pH = 3, pH = 3.5 and pH = 4. Variation of electric voltage used is 3 volts, 6 volts, 9 volts and 12 volts. The result of purity level analysis of the initial Fe metal at anode was 84,48 %, while after electrolysis process there was an increase of metal purity attached to the cathode of 96,58 %. The result showed that the effect of pH variation of the electrolyte solution on the mass produced in the electrolysis process in the A1, A2, A3, A4 and A5 samples was 0,09; 0,07; 0,02; 0,02; and 0,02 g. The greater the concentration of H+ of the electrolyte solution the more mass produced. In variable voltage of electricity on samples A11, A21, and A31 mass produced that is equal to 0,14; 0,13; and 0,10 g. While the mass of A41 sample did not increase in the cathode produced during the electrolysis process. The greater the voltage used in the electrolysis process the greater the mass produced.
