Background: Various company resources involved in the business become a common commodity that must be used the distinguished is how the management needs manage its information system. Risk Management is one of the arts and sciences in identifying, analyzing, and responding to every risk throughout the product lifecycle.Objective: to investigate the effects of risk management on the performance of the company so they have competitive advantage to maintain their market profits.Methods: We identified and analyzed the weaknesses of one of the Fishing Companies (Pt. Nusantara Fisheries) located in Eastern Indonesia (Ambon) the capital of Maluku province. The approach was carried out by interviewing the highest chair (Branch Head), then 2 administrative and information systems staff, 6 raw material processing company technicians, 4 agents and 16 suppliers from 4 different vessels. The questionnaire was used to find out how important the risk management in the logistics and supply chain so that it found out the risks that were affecting their performance.Results: The results of this approach provided almost 90% of the information needed to analyze the response of this company in the Supply Chain Management conceptual strategy because it had a positive impact on selection, determined the scope of the company, developed a realistic schedule and estimated the right target costs in involving team members to determine strengths and weaknesses in the Supply Chain Process.Conclusion: the companies were able to minimize business failures and the strategy had positive impact.

Background: Educational data mining is an emerging trend, especially in today Big Data Era. Numerous method and technique already been implemented in order to improve its process to gain better understanding of the educational process and to extract knowledge from various related data, but the implementation of these methods into Decision support system (DSS) application still limited, especially regarding help to choose university sub majors .Objective: To design an academic decision support system (DSS) by adopting Theory of Reasoned Action (TRA) concept and using Data Mining as a factor analytic apporach to extract rules for its knowledge model.Methods: We implemented factor analysis method and decision tree method of C.45 to produce rules of the impact course of the sub- majors and the job interest as the basic rules of the DSS.Results: The proposed academic decision support system able to give sub majors recommendations in accordance with student interest and competence, with 79.03% of precision and 61.11% of recall. Moreover, the system also has a dashboard feature that shows the information about the statistic of students in each sub majors.Conclusion: C.45 algorithm and factor analysis are suitable to build a knowledge model for Academic Decision Support System for Choosing Information System Sub Majors Bachelor Programs. This system could also help the academic adviser on monitoring and make decision accordance with that academic information

Underpricing is a condition which shows that stocks price at primary market is lower than the stocks price at secondary market. This research was aimed to find out the influence of financial and non-financial information in the form of Debt to Equity Ratio (DER), Return on Equity (ROE), underwriter reputation, and the percentage of stocks offering to underpricing of stock prices in companies that conducted Initial Public Offering (IPO). The population in this research were the companies that conduct IPO listed in the Indonesian Stock Exchange in the period time of 2013-2017. The sampling technique was purposive sampling method and there were obtained 52 companies as the samples. The used data were the secondary data in the form of the data of companies that carry out IPO and listed in IDX in 2013-2017and the prospectus of the companies.The data analysis technique was multiple linier regression. The result of this reseach showed that Return on Equity (ROE) and Underwriter Reputation has a negative significant effect to underpricing, while Debt to Equity Ratio (DER) and Percentage of Stocks Offering doesn’t have significant effect to underpricing.

Knowledge, ethic, and religion are three combinations that can’t be detached from life structure. Human created to embrace religion, and religion practiced with ethic values, whereas knowledge build from a series of religious practices and ethic values. Islamic Information and Communication Technologies (Islamic ICT) is a discipline that manifested as representation of knowledge, ethic, and religion that collaborated on practical-empirical aspect, not separated on knowledge development. Therefore, knowledge, ethic, and religion are a harmonization for human being to work goals. Keywords: knowledge, ethic, religion, Information and Communication Technologies (ICT).

This paper discusses how to ensure security, i.e., confidentiality and integrity properties, for data in IoT applications. While confidentiality could be assessed via information flow analysis, integrity is ensured by error-correcting codes. In addition to errors, many communication channels also cause erasures, i.e., the demodulator cannot decide which symbol the received waveform represents. The paper proposes a method that might correct both errors and erasures together. Our method is efficient in reducing memory storage as well as decoding complexity.

Using One-hop and Two-hop Neighbouring Information to Defend Against Sybil Attacks in Stationary Wireless Sensor Network Elham Bahmani; Sheida Dashtevan; Abdusalam Shaltooki; Mojtaba Jamshidi

Considering the application of wireless sensor networks (WSNs) in critical areas like war fields, establishing security in these networks is of great challenge. One of the important and dangerous attacks in these networks is the Sybil attack. In this attack, a malicious node broadcasts several IDs simultaneously. Thus, the malicious node of the adversary attracts high traffic to itself and disrupts routing protocols and affects other operations of the network like data aggregation, voting, and resource allocation, negatively. In this paper, an efficient algorithm based on one-hop and two-hop neighborhood information is proposed to detect Sybil nodes in the stationary WSNs. The proposed algorithm is executed locally with the collaboration of neighboring nodes. The main purpose of the proposed algorithm is to increase the accuracy of detecting Sybil nodes under various conditions including the condition in which a malicious node broadcasts a few numbers of Sybil IDs which is the shortcoming of most existing algorithms. The proposed algorithm is simulated in MATLAB and its efficiency is compared with two similar algorithms in terms of true and false detection rates. The proposed algorithm not only reduces communication overhead but also increases the accuracy of detecting Sybil nodes compared to two similar algorithms.

Background: Pentavalent immunization was developed by the Strategic Advisory Group of Experts on Immunization (SAGE) by adding Hib vaccine and combined it into one single preparation. The advantage of using the pentavalent vaccine is the protection of five diseases, easy to use and reducing drop out numbers. The aim of this study was to determine the relation of mother's knowledge, attitude, and information source with pentavalent immunization's completeness in Cipondoh Primary Health Care. Method: This was an analytical non-paired comparative study with cross-sectional design by consecutive sampling technique. There were 105 respondents. The samples were mothers who have minimal 6 months old baby in Cipondoh Primary Health Care work area. Data were collected using questionnaires. Results: The results of bivariate test using chi-square shows there was a relation between mother's knowledge and pentavalent immunization's completeness (p-value=0.001; OR=6.1; CI=2.1-17.2), mother's attitude and pentavalent immunization's completeness (p-value=0.027; OR=3.5; CI=1.1-11.3), mother's information source and pentavalent immunization's completeness (p-value=0.011; OR=4.4; CI=1.5-12.4). Conclusion: There was a relationship between maternal knowledge level, maternal attitude, information source and pentavalent immunization's completeness.
