Abstract

ABSTRACT- A BCNO phosphor was successfully synthesized using a microwave method and atmospheric pressure. The phosphors were prepared from precursors containing boric acid as a boron source, urea as a nitrogen source and poly ethylene glycol (PEG) as a carbon source. The carbon sources were varied by PEG MW 1000, MW 6000 and MW 20000.  The objective of this research is to study the effect of variations in the carbon source to the luminescence properties of BCNO that synthesized using microwave. The emission wavelength of the samples are in violet area (380-450 nm) and the highest emission intensity was 47 a.u. produced by BCNO which using PEG MW 20000 as the carbon source.

Abstract

The prototype batteries was succesfully made by using activated carbon. This research aimed to examine the effect of pore size on the electrical properties of activated carbon which is used as a battery-making material. Activated carbon is synthesized using H3PO4 activator with concentration variations (mass/volume) of 5%, 10%, 15%, 20%, and 25%. The carbonization was carried out at 400 °C for 1 hour, while activation at 700 °C for 1 hour. The result showed, the pore size effect on the electrical properties of the activated carbon in the battery prototype, especially for the capacitance and internal resistance of the material which has a correlation of 90% and 90.2%, respectively. The sample with 25% H3PO4 has the best pore size of 5.43μm. As the pore size of the activated carbon increases, it has caused increased capacitance and decreased internal resistance of the material. With the pore size of 5.43μm, the capacitance is 5.88mF/g and the internal resistance of the material is 662.02Ω.

Abstract

Penelitian ini menyelidiki degradasi fotokalitik dari larutan Metilen Biru (MB) yang diberikan pra-perlakuan Polypropylene (PP)/TiO2. PP/TiO2 dibuat dengan proses thermal milling pada suhu 175°C selama 40 menit untuk melapisi permukaan PP dengan TiO2. Hal ini bertujuan untuk melapisi permukaan polipropilena (PP) dengan TiO2 sebagai upaya modifikasi material karena sukarnya pemisahan TiO2 dari limbah. UV-vis digunakan untuk mengkarakterisasi sifat fotokatalitik dari sampel. Sebanyak 84,70 g sampel digunakan untuk mendegradasi 3,12.10-6 M MB (250 ml limbah artifisial). Dengan tata eksperimen yang sama, sampel yang sama digunakan berulang sebanyak delapan kali untuk mempelajari efek penggunaan berulang pada aktvitas fotokatalitik material. Dari penelitian yang telah dilakukan, ditemukan bahwa hampir 90% (rata-rata) MB tereduksi oleh PP/TiO2 selama tiga hari percobaan dan 8 kali pengulangan. Yang lebih penting, komposit PP/TiO2 berpotensi untuk dapat digunakan berulang (lebih dari 8 kali) dengan sedikit penurunan kemampuan fotodegradasi.
