Abstrak

Penelitian ini bertujuan untuk mengetahui pengaruh variasi massa karbon sekam padi pada perlakuan blender, sonifikasi, dan blender+sonifikasi menggunakan blender tanpa pisau terhadap sintesis GO berdasarkan spektrofotometer UV-Vis, mengetahui pengaruh perlakuan blender, sonifikasi, dan blender+sonifikasi terhadap hasil koefisien absorbansi terhadap material GO  berdasarkan spektrofotometer UV-Vis. Penelitan ini dimulai dengan membuat larutan sampel analit variasi massa 1 gram, 2 gram, dan 3 gram dengan menambahkan detergen sebanyak 0,8 gram serta air 250 ml dengan memberikan perlakuan blender+sonifikasi, blender, dan sonifikasi. Masing-masing perlakuan dilakukan selama 2 jam tanpa jeda, serta alat blender yang tidak menggunakan pisau. Metode yang digunakan dalam penelitian ini yaitu liquid phase exfoliation. Selanjutnya membuat larutan blanko dari detergen 0,8 gram dan air 250 ml dengan memberikn tiga perlakuan yang sama  dengan larutan analit. Setelah sampel sudah jadi didiamkan semalam agar beberapa lapis grapheneterpisah dari kumpulan graphene. Proses karakterisasi material GO dilakukan dengan pengujian spektrofotometer UV-Vis. Pengaruh variasi massa abu sekam padi pada perlakuan blender + sonifikasi dan blender menunjukkan bahwa semakin besar massa maka semakin besar panjang gelombang dari puncak absorbansi. Hal ini mengindikasikan adanya pergeseran puncak absorbansi menuju panjang gelombang yang lebih besar, atau terdeteksi adanya redshift. Sedangkan untuk perlakuan sonifikasi tidak memenuhi hukum lambert-beert. Pengaruh perlakuan blender, sonifikasi, dan blender+sonifikasi terhadap hasil koefisien absorbansi yaitu pada perlakuan blender memiliki nilai gradien lebih besar daripada blender+sonifikasi tetapi untuk nilai koefisien absorbansinya perlakuan blender+sonifikasi memiliki nilai lebih besar daripada blender.

Kata Kunci: graphene, GO, blender, sonifikasi, blender+sonikasi, blender tanpa pisau.

ABSTRACT

This research is aimed to figure out the effect of mass variation of carbon rice husk on blender, sonification, and blender+sonification using knifeless blender to synthesis of GO based on UV-Vis spectrophotometer, figure out the effect of blender treatment, sonification, and blender+sonification to the absorbance coefficient result to GO material based on UV-Vis spectrophotometer. This research is commenced by making an analite sample solution with variation mass of 1 gram, 2 grams, and 3 grams with adding the detergent as many as 0.8 grams and 250 ml of water with giving blender+sonification, blender, and sonification treatment. Each treatment is done for 2 hours without a pause, as well as the knifeless blender tool. In this research use liquid phase exfoliationmetod. Then, making a blank solution from 0.8 grams of detergent and 250 ml of water by giving 3 similar treatment with an analit solution. After that, the sample is put in the safe room for a night in order to several layers of graphene is seperated from the batch of graphite.The characterization process of GO material is performed with UV-Vis spectrophometer test. The effect of mass variation of rice husk to both blender + sonification and blender treatment shows that the bigger mass of the rice husk, the longer wavelength from the absorbance peak. This indicates the presence of absorbance peak shifting toward the bigger wavelength, also known as redshift phenomena. Whereas for the treatment of sonification doesn’t meet the lambert-neert law. The effect of treating the blender, sonification, and blender+sonification to absorbance coefficient result is on the treatment of the blender which has greater gradient value than blender+sonification, yet for the absorbance coefficient value, blender+sonification has greater value than blender.
