Solar energy in tropical area is one of potential renewable energy due to the sun always shines along of a year involving in dry and rainy season. The power output of solar panel is depended on climate parameters including solar radiation, humidity, cloud, rain, and dust decomposition. This paper explores the climate parameters that potentially affect the power output of solar panel and estimate the solar energy in such region based on its climate parameters. To measure the climate and electric data, this work develops in house digital climate and electrical data recording that saves the data of humidity, wind speed, temperature, solar irradiance, current, and voltage sensors. The data are analyzed by equation of correlation between climate parameters, power output and solar panel temperature. The protoype of digital recording is tested at Politeknik Negeri Semarang located on latitude -7.054044 and longitude 110.434695 during dry season. Based on the correlation analysis of several climate parameters to solar panel output power, the correlation value of the humidity is -0.85, ambient temperature=0.87, solar irradiance=0.98, wind speed= -0.34 and cell temperature=0.83. This work can be used to estimate the potency of solar panel output power in specific location using climate data.

In this paper, we will generalize the multi link internet charging scheme in multi class QoS network. This scheme is designed according to the base price, quality premium and quality of service to help the service provider to set up the parameters to optimize the service provider’s profit and to serve better quality of service. The objective function is formed by setting up the base price as a constant and setting up quality premium as a parameter and a variable. Models are in form of Mixed Integer Nonlinear Programming Problem and are solved by using LINGO 13.0 to obtain the optimal solutions. The results show that in case when we set up the base price as a parameter with varying the quality premium, fixing the sensitivity price of user I in class j and also varying the sensitivity of class j, the highest optimal solution was achieved. The modified model also gives better optimal solution compared to original model. It means that by fixing base price, ISP is able to goal its objective by recovering cost and promoting certain services.

In this paper, a critical view of the utilization ofcomputational intelligence approach from the text steganalysisperspective is presented. This paper proposes a formalization ofgenetic algorithm method in order to detect hidden message on ananalyzed text. Five metric parameters such as running time, fitnessvalue, average mean probability, variance probability, and standarddeviation probability were used to measure the detection performancebetween statistical methods and genetic algorithm methods.Experiments conducted using both methods showed that geneticalgorithm method performs much better than statistical method,especially in detecting short analyzed texts. Thus, the findings showedthat the genetic algorithm method on analyzed stego text is verypromising. For future work, several significant factors such as datasetenvironment, searching process and types of fitness values throughother intelligent methods of computational intelligence should beinvestigated.
