Abstract

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

Abstract

Naval Base plans to establish a naval base at the type of "C". Following this matter, the Regional Government of Islands District provides 3 (three) alternative places namely in NB1 Bay, NB2 Bay, and NB3 Bay for the location of dock and office. In the selection of Mentawai base this method using Borda and Promethee, this is used because the method can consider alternative evaluation based on factors that are qualitative and quantitative (Pavic, 1991). Based on the research of Borda method calculation on 16 base selection criteria, it is found that criteria (K1) of Sailing Flow has the highest weight value that is equal to 10.9% and for the lowest criteria weighted value is occupied by criterion (K14) that is Political Condition of 2%. For the results of ranking against the alternative using the Promethee method obtained NB2 Bay is the best location to serve as the location of the base of the Naval Base. From the research results can be concluded that the model of decision making by combining Borda and Promethee method is a way to develop the logical relationships that underlie the problem of decision making into a mathematical model that reflects the relationships that occur between the criteria involved.

Abstract

Increasing population growth also contributes to the increasing need for homes or dwellings as basic human needs. Many ways people do to meet these needs, among others, by buying from someone else, building it yourself or by buying a house in a housing developer. Houses besides being a basic human need, it is also used as an indicator of one's success and as an asset for business development and an increase in the economic value of the owner. Prospective home buyers certainly have criteria that are considered in choosing a house. Many of the existing criteria are often followed by the availability of more than one choice of the house to be able to meet these criteria. Therefore, the writer tries to try to make a Decision Support System in a Home Purchase that will later help prospective home buyers in deciding which house to buy. The decision-making method used in this system is an analytical hierarchy process (AHP) as a form of decision-making model that is suitable for multi-criteria and multi-alternative problems with the main input being human perception. Combined with the Borda method which is one method of group decision making that can combine the results of perceptual analysis (the results of AHP analysis) from several decision makers. it is necessary to have a group decision-making technique (group decision support system). So that the resulting home purchase decision can be accepted by all decision makers (family). From the results of the calculation and voting process, House X was chosen with 9 votes. Keywords: Home Purchase, Analytical Hierarchy Process, Borda

Abstract

Presently, the rapidly increasing population growth has been shown to create the growing needs of sea transportation services, both for freight and passengers. The augmentation of sea transportation fleets causes the ever-increasing number of all types of ships and the vessel traffic congestion in many connected sailing lanes. The development of sea transportation media significantly affects the potency of sea pollution. Therefore, it requires an analysis of the development feasibility of the Reception Facility in Tanjung Perak Port Surabaya. The first analysis is by doing the evaluation of investment feasibility based on the law, market, technical and financial aspects. After that, the measurement is done by using the methods of Net Present Value (NPV), Payback Period (PP), Internal Rate of Return (IRR), Average Rate of Return (ARR), Profitability Index (PI) and investment risk analysis. In this research, the gained NPV is about Rp. 431.257.167, PP value about 8 years 9 months 26 days, IRR 22,695%, ARR 30,32%, PI about 1,39, so the infrastructure investment program of Reception Facility in Tanjung Perak Port Surabaya is feasible to be carried out. Keywords: Feasibility Study, NPV, PP, IRR, ARR, PI, Investment Risk

Abstract

The scheduling of production floor is a sophisticated problem which seeks the optimal task allocation to certain resources under a number of constraints. The use of optimization techniques facilitates the determination of acceptable solutions that considered optimized for a specific problem. This paper proposes production scheduling solution based on job priority in a Non-Deterministic Polynomial-time hard (NP-hard) problem. The case study was taken from the Spirit Aerosystem Project, particularly in the Inboard Outer Fixed Leading Egde - Drive Rib 1 component production process. The problem consists of finding the machine operations schedule, taking into account the precedence constraints. The main objective is to minimize total delays or tardiness. The genetic algorithm was employed to determine the optimized production scheduling solution. The parameter for genetic operators in this study consists of a roulette wheel selection, 1 elitist chromosome, partially-mapped crossover mutation and 1 point mutation. The termination condition was achieved when there has been no improvement in the population for 30 iterations.The results show that the algorithm is capable to generate optimum production schedule with minimum tardiness for the given problem. Keywords: Genetic algorithm, job shop problem, scheduling problem

Abstract

The level open unemployment is a value that shows the number of working-age population who looking for work, is preparing a business, feels impossible to get a job or already have a job but have not started working and often used for measured employment. Like at Central Java has increasing the total population at 2014 and have high total investation whereas should be can getting more employment, but actually still give high unemployment about 996.344 population at 2014. So that, in this research used nonparametric regression approach which multivariate adaptive regression splines (MARS) for modeling the level open unemployment in Central Java at 2014 because the level open unemployment in Central Java predicted influence by some factors. This research resulted in the best modeling for level of open unemployment in Central Java Province with value of GCV minimum that obtained at 0,396 with R-square at 86,5 percent as well as the predictor variables were entered into the model as much as three, namely the total population with interest rate of 100 percent, the minimum wage with interest rate of 41,955 percent, and the total working population with interest rate of 39,547 percent. Keywords: MARS, Nonparametric regression, Level of open unemployment
