Sariasih No.54, Sarijadi, Bandung 40151, Indonesia Abstract This paper studies and analyses the effect of Ipv6 multicast transmission for end-to-end interconnection. At the end-to-end interconnection addressing system, two types of protocols have been introduced: IPv4 and IPv6. There is a fundamental difference in transmission characteristics between both broadcasting properties in IPv4 and multicast on IPv6 even though both works on the transport layer using TCP protocol. However, the emergence of the term TCP6 used to mark the IPv6 transmission performance domain raises questions about whether the transmission characteristics contribute to the mention of TCP6. This paper provides an explanation of the results of the analysis in an effort to answer the question through end-to-end interconnection experiments by comparing the timeout performance as a result of the broadcast properties of IPv4 and multicast on IPv6 using Karn Algorithm with throughput test parameters. The experimental results show that the throughput value through RTT analysis is relatively similar, not more than 0.1% difference. The conclusion is that TCP and TCP6 are talking about the domain of activity and technical performance. They need correspondence that identifies characteristics in understanding the context of interconnection requirements between devices, broadcasts or multicast.

Implementation and Experimental Analysis of Random Forrest in R Parallel Computing Nur Azizah, Yaya Wihardi, Lala Septem Riza Department of Computer Science Education, Universitas Pendidikan Indonesia Abstract Random forest is a method for building models by combining decision trees or decision trees generated from bootstrap samples and random features. A common problem that often occurs when implementing random forest in a single core is the long processing time because it uses a lot of data training and builds a lot of tree as the model as well. Therefore, this study proposes the random forest method with parallel computing implemented in the R programming language. Several datasets are used in the experiments, such as the Iris dataset, the quality of the wine, and the diagnostic data of female diabetes Pima Indians. Results obtained from the experimentation show that the computational time used when running random forest with parallel computing is shorter than when running a random forest using only a single processor. It means that the implementation has been successful.

e-Portofolia Assessment Model on Collaborative Problem Solving (CPS) Learning Based on Digital Learning Environment Heri Sutarno, Budi Laksono Putro, Rizky Rachman Judhie Putra, Erna Piantari Computer Science Education Department Faculty of Mathematics and Science Indonesia University of Education Abstract The 21st Century Skill is the knowledge and skills needed to deal with the problems of the 21st century. There are a number of views on 21st century skills proposed based on the research of various research institutes (P21, EnGauge, ATC21S, NETS / ISTE, EU, and OECD), on what competencies and skills humans must have in the globalization era. This study uses the concept of 21st century skills published by The University of Melbourne in the KSAVE framework (Knowledge, Skills, Attitudes, Values, Ethics). The KSAVE framework illustrates that collaborative problem-solving (CPS) lessons, and learning through a digital network are the glue of 21st century skills (Griffin and Care, 2015). Learning CPS is a glue for the achievement of critical thinking skills, problem solving, decision-making and collaboration. While learning through a digital network is a combination of information literacy skills, ICT literacy, personal responsibility, and social responsibility. This study aims to create an e-Portfolio assessment model on CPS learning based on learning through a digital network in the form of moodle learning management system (LMS). e-Portfolio is a digital portfolio to record students learning process and performance in proof of electronic data collection process using LMS. e-Portfolio aims to show students learning outcomes in terms of Knowledge, Skills, Attitudes, Values, Ethics based on the KSAVE framework.

STRATEGY SECURITY INFORMATION TECHNOLOGY MODEL FOR DECISION TOOL IN E-GOVERNMENT MANAGEMENT Faiz M Kaffah (a*),Aedah Binti Abd Rahman (b),Syopiansyah jaya putra (b),Beki Subeki(b),Khaerul Manaf(b) (a) Universitas Informatika & Bisnis Indonesia (b) Asia E University (b) UIN Syarif Hidayatullah Jakarta (b)Universitas Sangga Buana YPKP (b) Universitas Sangga Buana YPKP Abstract Handling information security management is an absolute thing done in organizations that have information systems to support organizational operations. An information system consisting of software and hardware assets that manages data and information spread across the network and the internet, making it vulnerable to threats. Therefore it takes investment and cost to secure it. The costs incurred for this purpose are not small, but investment spending and information security costs require serious handling to be more effective and targeted. Model This security strategy is used to evaluate alternative strategies to demonstrate the effectiveness of investment and cost of managing information security through simulation of policy changes. This model is a method to describe dynamic and complex manganalian model and systems consisting of interrelated variables in the form causal relationships and feedback between the good variables that reinforce or provide balance. Simulations using dynamic system models in this study illustrate that risk assessment management followed by efforts to reduce vulnerability has a major impact on information security management. By making a difference in the variable value of the probability of reducing the vulnerability, it provides an alternative choice in risk management of information security investment to achieve the overall cost effectiveness of information security management.
