Abstract

The 2013 curriculum for science education trains students to learn independently and creatively. The teaching and learning process in it uses laboratory-based learning, where students are given the opportunity to experience and do things themselves. Throughout the process, they observe an object, analyze it, prove it, and draw their own conclusions about an object, situation, or process. These activities can enhance students' understanding. Process skills in science are skills that can help students solve various problems, and by applying laboratory activities, they can develop these process skills. The classification of science process skills is divided into two categories: basic process skills include observation, classification, measurement, and inference. Meanwhile, integrated science process skills include formulating hypotheses, identifying and controlling variables, conducting experiments, and interpreting data. Through science process skills, the concepts acquired by students will be more meaningful because their thinking skills will be further developed. Information technology and computers have developed so rapidly and have an incredible impact. Through virtual laboratories, the learning process becomes more interesting and interactive, teaching time can be reduced, the quality of learning can be improved, and the teaching and learning process can be done anytime and anywhere.

Abstract

Metal organic framework-derived carbons (MOFDCs) are materials with great potential and can be used as electrochemical energy storage because these have a large surface area and pore structure that can be adapted to needs. MOFs have porous crystals in which metal ions or clusters are linked by organic ligands. The purpose of this study was to determine the physical and electrochemical properties of MOF5 synthesized at different temperatures. The MOFs synthesis method which is classified as complicated can be simplified and the use of hazardous solvents can be reduced by means of partial substitution using water solvents. To prepare MOFs can be done in several ways, such as liquid phase epitaxy, supersonic cold spraying, direct gas phase preparation, and interface-assisted synthesis. MOFs have applications in optics, sensing, catalysis, adsorption, and modeling, as well as electrochemical energy storage. Potential application as an interesting electrode material to be studied through the synthesis method. In this study, MOF5 was synthesized at temperatures between 200°C-600°C. To prepare MOF5, zinc nitrate tetrahydrate and acetic acid were dissolved in DMF (N, N-dimethyl formamide). The remaining precipitate (MOF) was immersed three times in DMF and three times in chloroform for 24 hours for each immersion. In general, different MOF5 synthesis affects the microstructure, elemental content, optical properties (transmittance and absorbance), electrical properties, and electrochemical properties

Abstract

Senyawa kurkumin telah dimanfaatkan dalam berbagai bidang, salah satunya dibidang fotovoltaik sebagai pemanen energi matahari yang akan dikonversi menjadi energi listrik. Keterbatasan dari senyawa ini adalah tidak stabil terhadap cahaya matahari karena adanya gugus keton dan gugus hidroksil. Kedua elektron bebas pada gugus ini dapat berinteraksi dengan logam membentuk senyawa kompleks. Pada penelitian ini, pengaruh ion logam Cu2+ terhadap sistem kristal dan stabilitas dikaji. Kurkumin yang digunakan dalam penelitian ini adalah kurkumin komersial yang telah dipurifikasi. Kurkumin dalam pelarut methanol dilarutkan bersama CuSO4 dengan perbandingan mol 1:2. Setelah campuran di refluks kemudian diperoleh endapan dengan warna kuning tua. Endapan yang telah dikeringkan kemudian dikarakterisasi menggunakan spektrofotometer XRD, FT-IR, dan UV-Vis. Tidak banyak perubahan yang teramati pada pola difraksi sinar-X, IR maupun UV-Vis. Sedikit pergeseran teramati mengindikasikan interaksi antara kurkumin dengan Cu2+. Pengujian fotostabilitas dilakukan dengan melarutkan senyawa kurkumin dan Cu2+-kurkumin dalam dimetilsulfoksida (DMSO) dimasukan dalam ruang dengan sumber lampu UV 10 watt. Pengamatan dilakukan selama 10 hari dan diukur absorbansi maksimum setiap satu hari menggunakan spektrofotometer UV-Vis. Hasil analisis absorbansi menunjukkan terjadi pergeseran dan puncak baru pada senyawa kompleks pada panjang gelombang diatas 500 nm. Melalui perhitungan menggunakan orde 0, senyawa kurkumin dan Cu2+-kurkumin akan terdegradasi seluruhnya (absorbansi sama dengan 0) pada hari ke-16 dan ke-55. Kata Kunci: Senyawa analog kurkumin; Cu2+-kurkumin; Fotostabilitas; tetapan laju degradasi.
