Afida, LaelyNur (2014) Sintesis Keramik Berpori Berbahan Dasar Lumpur Lapindo Menggunakan Cetakan Nata De Coco Yang Dibuat Dengan Variasi Kadar Gula. Sarjana thesis, Universitas Brawijaya.
Abstract
Lumpur Lapindo mengandung Fe 2 O 3 , SiO 2 , dan Al 2 O 3 berturut-turut 62,10%, 15%, dan 4,8%, yang berpotensi untuk dijadikan bahan dasar keramik. Tujuan dari penelitian ini adalah untuk mengetahui karakter fisik keramik berpori yang dibuat menggunakan cetakan nata de coco serta mengetahui pengaruh variasi kadar gula dalam sintesis. Sintesis keramik diawali dengan preparasi sampel dengan proses refluks untuk mengurangi kadar Fe 2 O 3 serta penambahan larutan Mg(II) 1% untuk meningkatkan kekerasan keramik. Terdapat dua kelompok sampel, A dan B. Keramik A disiapkan dengan mencanpurkan lumpur Lapindo dan larutan gula 10%, keramik B menggunakan larutan gula 12%. Selama fermentasi, sampel diaduk dan tidak diaduk dibawah kondisi steril dan tidak steril. Karakterisasi keramik berpori meliputi susut bakar massa, densitas, dan luas permukaan yang menggunakan metilen biru. Hasil penelitian menunjukkan sampel B2 mengalami susut bakar massa tertinggi (65,71%). Sampel A1 memiliki luas permukaan maksimum (8,56703 m 2 /g ), sedangkan densitas tertinggi (0,9984 g/cm 3 ) pada sampel A2. Disamping itu, perbedaan konsentrasi gula tidak berpengaruh secara signifikan terhadap sifat keramik
English Abstract
Lapindo Mud Consists Of Fe 2 O 3 , Sio 2 , And Al 2 O 3 At The Concentration Of 62.10%, 15%, And 4.8% Respectively, Which Are Potential As Ceramic Raw Material. The Objective Of This Research Is To Identify The Physical Characteristics Of Porous Ceramic Made By Using Nata De Coco As The Template And To Investigate The Effect Of Glucose Content Variation In The Synthesis. The Synthesis Of Ceramic Begins With Sample Preparation With Reflux Process To Reduce Fe 2 O 3 –Content Which Is Followed By Adding Of Mg (II) 1% Solution In Order To Increase Ceramic Hardness. There Are Two Groups Of Samples, A And B. Ceramic Material A Were Prepared By Mixing Lapindo Mud And Glucose 10% Solution, Prior To Fermentation, While The Other Ceramic B Used Glucose 12% Solution. During Fermentation, The Samples Were Stirred Or Not Stirred Under Sterile Or Unsterile Conditions. Porous Ceramic Characterization Includes Losing Mass, Density, And Surface Area Measurement. The Results Show That B2 Sample Has The Highest Losing Mass (65.71%). A1 Sample Has The Maximum Surface Area (8.56703 M 2 /G), While The Highest Density (0.9984 G/Cm 3 ) Was Found At Sample A2. In Addition, The Different Glucose Concentration Does Not Affect The Properties Of The Ceramic Significantly.
