ISOLASI SILIKAT DARI SEKAM PADI

Isolation of Silicate from Rice Husk

Author :
DUR, SAJARATUD 




ABSTRAK

The rice husk which content silica are by product of the grinded paddy about 20 weight dried. The research target are to isolate silicate from the rice husk that are applied as raw material and to know the phenomenon happened when silicate are produced. There are stages when isolating silicate those stages are the material and instrumental preparation pretreatment paralysis melting dilution and finally measurement and data analysis. The research variables consist of pretreatment acid leaching and non acid leaching the paralysis temperature 750 800 850C and the paralysis time 60 and 90 minutes. Acid leaching used are HCl 3N. And the size of the particles of rice husk ash are 100 mesh and above it. The rice husk ash and sodium carbonate ratio are 1 3. The melting process worked at 950C for 20 minutes. The dilution of mixed solid are included into 100 mL aquadest. The screening process will be stopped if no more precipitation happened and the evaporation will be stopped if the solution retained 10 mL volume. All of the structure of silica in the rice husk and the structure of silica in rice husk ash are amorf. Acid leaching can remove the metal oxide CaO and reduce the other metal oxide. The rice husk weight will lack after the acid treatment because part of the impurities has been extracted out of the rice husk. Every 6.5277 grams of wet rice husk produced 23.62 - 31.79 weight-ash and 0.06099 - 1.51442 yield. Resulted from the experimental design the most affecting factors when yield is produced are temperature of paralysis and pretreatment. The product quality determined by yield and ratio between Si02 and Na2O of the product.


ABSTRACT

Sekam padi merupakan hasil samping penggilingan padi sekitar 20 dari gabah kering giling. Sekam mengandung silica. Dalam penelitian ini bertujuan untuk memperoleh silikat dengan memanfaatkan sekam padi sebagai bahan baku dan mengetahui fenomena-fenomena pada proses perolehan silikat meliputi proses persiapan bahan dan alat pretreatment pirolisa pelelehan pelarutan pengukuran dan pengolahan data. Variabel penelitian terdiri dari perlakuan awal acid leaching dan non acid leaching suhu pirolisa 750 800 850C dan waktu pirolisa 60 dan 90 menit. Acid leaching menggunakan HCl 3N Ukuran partikel abu sekam padi 100 mesh ke atas. Perbandingan abu dan natrium karbonat 1 3. Pelelehan dilakukan pada suhu 950C selama 20 menit. Pelarutan dengan 100 mL aquadest. Penyaringan selama dalam proses pelarutan dihentikan jika tidak terdapat endapan lagi dan penguapan dihentikan jika volum larutan telah mencapai 10 mL. Semua struktur silika dari sekam padi dan abu sekam padi adalah amorf. Acid leaching pada sekam padi dapat menghilangkan oksida logam CaO dan mengurangi oksida logam lainnya. Berat sekam setelah ditreatment berkurang karena sebagian impuritis telah diekstrak keluar dari sekam. Tiap 65277 gram sekam padi basah mengtmsilkan 2362 - 3179 abu dan 006099 - 151442 yield. Dari hasil disain eksperimen diperoleh faktor yang paling berpengaruh pada prosentasi yield adalah interaksi dua faktor yaitu suhu pirolisa dan treatment. Kualitas produk ditentukan olehjumlah silikat atau prosentasi yield dan rasio antara Si02 dan Na20 dalam produk.
