Target Set Selection

It is well-documented that social networks play a considerable role in information spreading. The dynamic processes governing the diffusion of information have been studied in many fields, including epidemiology, sociology, economics, and computer science. A widely studied problem in the area of viral marketing is the target set selection: in order to market a new product, hoping it will be adopted by a large fraction of individuals in the network, which set of individuals should we “target” (for instance, by offering them free samples of the product)? In this paper, we introduce a diffusion model in which some of the neighbors of a node have a negative influence on that node, namely, they induce the node to reject the feature that is supposed to be spread. We study the target set selection problem within this model, first proving a strong inapproximability result holding also when the diffusion process is required to reach all the nodes in a couple of rounds. Then, we consider a set of restrictions under which the problem is approximable to some extent.

Bentonite serve the purpose of substance adsorpsi because swelling ability and cation for exchange. But adsorption ability is limited so that require to be activated by strong acid to higher level adsorption of bentonite. This research use Ca-Bentonit activated by strong acid HCl. Cation Cu analysed by using Spektofometri Serapan Atom (SSA).  Result of research  indicate that the increasing of HCl concentration and activation time can improve the adsorption capacity of bentonite. Maximum HCl concentration at 1,6 M and maximum activation time at 24 hour. Optimum heavy bentonite at 4 gr of 100 ppm Cu solution and optimum contact time at 2 hour. Result from Cu isoterm adsorption is weight of adsorption have same range with Cu concentration
