dc.description.abstract | Penelitian ini bertujuan memanfaatkan limbah geothermal PT. Geo Dipa Energi Dieng sebagai bahan dasar pembuatan material silika Mobil Composition of Matter-41 (MCM-41). Limbah geothermal dipreparasi melalui pencucian dan pembakaran untuk meningkatkan kemurnian silika. Silika amorf disintesis menggunakan metode sol-gel, kemudian digunakan untuk membuat MCM-41 dengan dan tanpa penambahan Tetramethylammonium Hydroxide (TMAOH). Karakterisasi dilakukan menggunakan XRF, XRD, FTIR, dan SEM-EDS. Hasil menunjukkan bahwa pretreatment meningkatkan kemurnian SiO2 hingga 97,74%. Sintesis MCM-41 berhasil dilakukan, dengan penambahan TMAOH meningkatkan kemurnian silika menjadi 98,07%. Analisis XRD dan SEM mengkonfirmasi struktur mesopori khas MCM-41. Penelitian ini membuktikan potensi pemanfaatan limbah geothermal untuk produksi material mesopori bernilai tinggi. | |
dc.description.abstract | This research aims to utilize geothermal waste from PT. Geo Dipa Energi Dieng as a raw material for synthesizing Mobil Composition of Matter-41 (MCM- 41) silica material. The geothermal waste was prepared through washing and calcination to increase silica purity. Amorphous silica was synthesized using the sol-gel method, then used to produce MCM-41 with and without the addition of TetraMethylAmmonium Hydroxide (TMAOH). Characterization was performed using XRF, XRD, FTIR, and SEM-EDS. Results showed that pretreatment increased SiO2 purity up to 97.74%. MCM-41 synthesis was successful, with TMAOH addition increasing silica purity to 98.07%. XRD and SEM analyses confirmed the characteristic mesoporous structure of MCM-41. This research demonstrates the potential of utilizing geothermal waste for producing high-value mesoporous materials. | |
