OPTIMIZATION OF BEST COMPOSITE PRIMER AMINE IN HYBRID SILIKA-AMINE SYNTHESIS

Silica, one of most porous materials having a unique silanol group, that can be replaced with other functional groups for more specific purposes. One of highlights is replacement of silanol function groups with amine groups. Amines are highly reactive to the carbon dioxide gas, so the silica amine hybrid has potential to absorb the carbon dioxide gas. Amine is often used is a type of primary amine. This research is development of previous research. The results data showed a significant relationship between type and composition of modifying agent on characterization of amine silica hybrid. This research is focused on optimizing best amine primer composition on hybrid synthesis of silica amine to surface area and pore size. As modifying agent used APTS in ethanol, where the integration of numerical analysis, matrix computing, signal processing and graphics are expressed in mathematical notation using matrix laboratory to solve optimization problem. It was concluded that ethanol solvent yields adsorbents with better characterization than water solvents, whereas the addition of APTS as a source of amine compounds gives a significant effect where increase in APTS increments will decrease pores produced

Effect of environmental knowledge and concern toward attitude of green home buyers’ intention in Surabaya

Understanding consumers’ buying behaviour, as one of the important elements for green homes market growing, could increase green homes development in Surabaya. From previous studies in consumers’ buying behaviour of green products shows that they were influenced by Environmental Knowledge (EK), Environmental Concerns (ECs), and attitude. Meanwhile, attitude affects a person’s intention to perform behaviour; in the context of this paper is the behaviour of green home consumers’. Therefore, this study has an objective to examine the effect of EK and concern toward attitude on green home buyers’ intention. The data collection has gathered from 240 prospective home buyers. The findings of this study; first, the model shows that the measured variables is fit to empirical data in the field. Second, that EC has strong significant than EK toward attitude. Third, attitude toward green home has significant effect toward green home buyers’ intention
