This study aims to present diagnose of melanoma skin cancer at an early stage. It applies feature extraction method of the first order for feature extraction based on texture in order to get high degree of accuracy with method of classification using artificial neural network (ANN). The method used is training and testing phases with classification of Multilayer Perceptron (MLP) neural network. The results showed that the accuracy of test image with 4 sets of training for image not suspected of melanoma and melanoma with the lowest accuracy of 80% and the highest accuracy of 88.88%, respectively. The 4 sets of training used consisted of 23 images. Of the 23 images used as a training consisted of 6 as not suspected of melanoma images and 17 as suspected melanoma images.

The result of science literacy in Indonesian students has been satisfactorily yet. The government has introduced some new learning strategies. The research is aimed to finding some learning strategies can improved literacy science. The research was conducted in Indonesian school involving 213 participants who are divided into study groups using several learning strategies. Research involved all student on 10 th grade in that school. Improvement of science literacy was analyzed by N-gain and comparing some strategies of learning was analyzed by Anova followed Turkey. The results shows the impovement of science literacy in the learning by using scientific approach was not as good as inquiry approach, Argument Driven Inquiry (ADI), and Science Technology Education Matematics (STEM). The results of science literacy finding the improvement in science literacy of students who learn by using scientific approach comparing using scientific approach is similar to the one using Science Technology Scociety (STS) strategy.
