Indonesian Language Subjects are generally regarded as easy lessons and do not need to be studied by students and society. Based on this, various learning problems arose involving instructors, Indonesian language subjects, students who received lessons, teaching methods, facilities, ways to obtain, and the objectives of Indonesian language learning (Moeljono, 1989). The difference between each student in different learning differences. This causes the teacher to have limitations in measuring the level of understanding of students. Then a system is needed to predict the level of understanding of students. This prediction uses the classification method with the Naive Bayes algorithm. The class that will be used in this study is that students understand, are quite understanding and lack understanding. In this study, the authors used the Information Gain (IG) feature selection. The selected feature will be processed with the Naive Bayes classification algorithm, then the accuracy will be seen if it is not maximized, then the previous feature selection process will be done again to get the desired verification. From the tests that have been conducted, the results obtained which have a Gain value of more than 0.2 have the largest rating, reaching 90%. The features chosen from 17 included features of family members, residence status, mother's work, caregivers, family support, joining extracurricular activities, repeating lessons at home, length of study at home, reading at home, reading time at home.

Food classification is a classic problem that still becomes an interest for many researchers. Several studies have been conducted using only one type of food, which is fruit as the object of the classification. This research was conducted to improve the previous ones. This study uses five types of single food as its object. The method used is color feature extraction using YUV Color Moment, texture feature extraction using Haralick, and feature selection using Information Gain. The classification algorithm is K-Nearest Neighbor (KNN). The highest accuracy obtained is 94.26% obtained from the combined features of the two selected feature extraction methods. From these results, it can be concluded that the application of a combination of feature extraction methods, namely color and texture, and feature selection method greatly influence the food image classification process.

Handling information security management is an absolute thing to do for organizations that have information systems to support the organization's operations. Information systems consisting of assets both software and hardware that manage data and information that are spread over networks and the internet, make it vulnerable to threats. Therefore investment and costs are needed to secure it. Costs incurred for this need are not small, but investment expenditures and information security costs carried out need serious handling to be more effective and on target. The System Dynamics Model is used to evaluate alternative strategies to demonstrate the effectiveness of investment and the cost of managing information security through simulation of policy changes. System Dynamics are methods for describing models and systems analysis that are dynamic and complex, consisting of variables that influence each other in the form of causal relationships and feedback between variables that are either reinforcing or giving balance. Simulation using a dynamic system model in this study illustrates that the management of risk assessment followed by vulnerability reduction efforts has a very large impact on the management of information security. By making a difference in the value of security tools investment, this provides an alternative choice in information security risk management investments to achieve the effectiveness of the overall costs incurred in managing information security

This study aims to describe and analyze the implementation of the public information disclosure (PID) practices at the local governmental level. It was carried out in two municipalities in Central Java Province, namely, Magelang and Semarang Cities. The results of the study found many different outcomes in practicing PID in both cities. Compared to Semarang City, Magelang City is still lagging in infrastructure, system of technology and readiness of human resources in the area of information disclosure. The study revealed that PID tends to influence the commitment of local government official to be transparent, as the authority holder in providing information. In the Semarang City case, the local leader and his public officials are seriously handling this policy. The strong willingness of the local leader leads to implement of the regulation, establish proper infrastructure and provide skilled officers. As the result, local government administration is likely to be more accountable, transparent and thereby achieved higher public trust. The lesson learned is the more willing local leaders implement public information disclosure, the more accountable the local government becomes.

This study for the first time examines the relationship between health information inequalities and child healthcare access in Indonesia, a developing country has been cited as one biggest emerging Internet users in the world. Data come from the Indonesian National Socio-Economic Survey (Susenas) 2013, which comprises 1.25 million individuals, 250 thousands households, and 497 districts. The results of descriptive and instrumental variable analysis indicate trend of widening disparities across socio-economic status and geographical areas in Internet and child immunisation access. A strong evidence for the causal flow running from a motherâ€™s access to Internet to child immunisation is found. All instruments are highly correlated with motherâ€™s access to Internet but uncorrelated with child immunisation. Supply factors across districts â€“ particularly village health posts (posyandu) â€“ are associated with child immunisation. The results are robust against individual, household and district socio-economic characteristics associated with child immunisation access. The results suggest that increasing motherâ€™s access to Internet may bridge child immunisation disparities in Indonesia.
