This study assessed the potential of liquid smoke as substitute for nitric acid for production of rice husk silica using sol-gel method. The efficacy of liquid smoke was compared to that of 10% HNO 3 solution in terms of the volume required and the mass of silica obtained. Further evaluation was made by comparing the characteristics of the silica as revealed by several characterization techniques include Fourier infrared spectroscopy, x-ray diffraction, scanning electron microscopy, and particle size analysis. No significant difference between the volume of the liquid smoke and the HNO 3 solution required, as well as between the mass of silica obtained. Both samples display practically similar functionality and structure. The most interesting finding is that the silica obtained using liquid smoke exhibits more homogeneous surface morphology and narrower particle size distribution. Considering its environmentally friendly nature, it was concluded that liquid smoke is more advantageous than HNO 3 solution.

The development of an area is carried out with the aim of improving the welfare of its community. Through economic development, it is expected to be able to eradicate social problems, development and poverty. Poverty is a problem in any country because it is a complex and unfinished problem. One of the provinces that is still classified as poor is Aceh Province. One of the missions in Aceh Province is the mission in rural areas. BPS Aceh stated that rural poverty in Aceh Province in September 2020 was 17.96 percent while in urban areas poverty in Aceh Province was 10.31 percent (DLHK, 2021). Development in Aceh Province continues to be carried out in order to improve the welfare of its people, especially improving the welfare of rural communities. Even development in Aceh Province continues to increase but this is not followed by a decrease in existing rural poverty. The purpose of this study is to analyze the factors that influence rural poverty in Aceh Province. The analytical method used is multiple regression analysis. Based on the research, the factors that affect rural poverty in Aceh Province are the GRDP of the agricultural sector, income distribution and NTP. Meanwhile, labor absorption and land area do not affect rural poverty. The value of R square is 0.984 or the effect is 98.4%.
