Abstract

Nanopartikel silika telah disintesis dari sinter silika yang bersumber dari mata air panas Sentral, Solok Selatan, Sumatera Barat menggunakan metode kopresipitasi. Sintesis dilakukan dengan cara merendam sinter silika dengan HCl 10 M selama 12 jam dan direaksikan dengan NaOH 8 M, 9 M dan 10 M. Larutan disaring dan dititrasi dengan HCl 10 M hingga pH mencapai 1, kemudian dicuci dan dikeringkan dengan oven selama 5 jam dengan suhu 100 oC. Dari hasil karakterisasi X-Ray Diffraction (XRD) didapatkan bahwa sampel yang direaksikan dengan NaOH 8 M dan 9 M, menghasilkan fasa kristal dengan ukuran kristal berturut-turut 224 nm dan 138 nm, sedangkan sampel dengan konsentrasi NaOH 10 M memiliki fasa amorf. Berdasarkan hasil karakterisasi Scanning Electron Microscopy (SEM) didapatkan ukuran partikel rata-rata berturut-turut 506 nm, 245 nm, dan 202 nm.Kata kunci : nanopartikel, sinter silika, kristal, XRD, SEM

Abstract

Simbatan Village in Magetan has nature tourism, historical, cultural tourism, and Dewi Sri's cultural heritage site called Candi Simbatan, but it has not been managed optimally. This village also has quite a lot of people with disabilities with poor socio-economic conditions. In realizing the tourism village, Simbatan has problem, namely: does not master plan yet, food court, pedestrians in tourist locations that were still in the form of land, places for people with disabilities did not exist and their products were splashed batik and marketing collided. Solutions are carried out in stages, namely: making a master plan; improve infrastructure at tourist sites. In line with these efforts, solutions for persons with disabilities are: improvement of workshop shelters; skills training and production of goods as well as assisting with marketing. The aim of this activity is to combine the existing tourism potential with the activities and work of people with disabilities so that their welfare and independence can increase. The integration is carried out gradually and continuously to create a tourist village.
