Lumpur panas Sidoarjo merupakan salah satu bencana luapan lumpur panas yang memiliki dampak signifikan di Indonesia terhitung sejak 29 Mei 2006. Adanya bencana ini banyak menimbulkan kerugian kesehatan, lingkungan hingga ekonomi. Akan tetapi,dibalik kerugian tersebut ternyata terdapat banyak kandungan mineral dalam lumpur luapan yang dapat dimanfaatkan sebagai contoh silika. Tujuan penelitian ini adalah mengetahui kandunganmineral terutama silika dalam lumpur panas Sidoarjo yang dapat berpotensi sebagai sumbersilika sintesis. Sampel diambil pada permukaan lumpur panas Sidoarjo dengan radius 500 m, 1000 m, dan 2000 m dari pusat semburan. Instrumen yang digunakan adalah XRF (X-Ray Fluorescence) dan XRD (X-Ray Diffraction) dimana sampel ditempatkan dalam sampleholder dan diradiasi menggunakan sinar-X. Berdasarkan uji XRF, pada masing-masing radius diperoleh kandungan silika sebesar 45,0% (radius 500 m), 45,3% (radius 1000 m), dan 43,3% (radius 2000 m) yang merupakan senyawa oksida dengan kandungan terbesar. Hasil uji XRD juga menunjukkan kesesuaian dengan hasil uji XRF, dimana fase yang paling dominan dalam lumpur panas Sidoarjo pada semua radius adalah fase kuarsa (SiO2). Berdasarkan kedua hasil ini, dapat disimpulkan bahwa kandungan mineral lumpur panas Sidoarjo pada 3 radius berbeda memiliki kandungan yang relatif sama dan dapat berpotensi sebagai sumber silika yang bermanfaat dalam bidang pangan, industri, hingga dalam bidang katalis.

Based data from OECD, Indonesian students’ scientific literacy in 2018 is subaverage. Therefore, researchers do need analysis for developing the scientific literacy application based on Al-Qur'an and Sosio-Scientific issues. The purpose of this research is to obtain information from teachers and students’ perspective about the characteristics of ideal scientific literacy application. This research uses descriptive qualitative research methods. The research subjects consisted of 10science teachers and 300madrasah students from 4 districts in Malang Regency. Scientific literacy emphasizes the need for a balance between various abilities and requires skills in deciding Sosio-Scientific issues. Integration between science and religion is also highly considered in terms of avoiding free value of science. The results showed that the science literacy application development based on Al-Qur’an Sosio-Scientific issues is needed with certain criteria.Keywords: Al-Qur’an; Scientific Abilities; Scientific Literacy; Sosio-Scientific Issues

The purpose of this research is to produce virtual laboratory media to support laboratory-based learning with the features mentioned above to make students become scientists with comprehensive understanding competencies and laboratory engineering skills. The virtual laboratory media was developed using the Lee Owens development method consists of five stages: analysis, design, development, implementation, and evaluation. The virtual laboratory based on triplet representations on chemical equilibrium material fulfils very feasible criteria for students to use as a learning resource. The percentage of product eligibility as a learning media is 86.15%, and in terms of the material, it is 85.71%. The results of small group trials in class XI students of SMAN 3 Sidoarjo showed that the virtual laboratory developed had met the very feasible criteria with an average percentage of 86.40%. The final result of this virtual laboratory has been revised based on comments and suggestions from validators and test subjects. Practically, the media developed is very useful to support practicum learning.
