Abstract

This article discusses several paradigms used in developing computer programs which is varied from the classical ? goto programming, until the modern one ? object oriented programming. In addition, the main features of each paradigm, the advantages and disadvantages of each paradigm and the comparation of procedural programming, the object oriented programming, and an additional feature like generic programming for the object oriented programming are also discussed in this article.

Abstract

This article discusses how to find a solution of a recursive function such as Fibonacci or factorial numbers without repetition. Therefore, a recursive function is considered a fixed-point of non-recursive function. To calculate the fixed-point, we can use Y Combinator, a non-recursive functions to perform memoizing recursive function. This method can significantly reduce the execution time of recursive functions.

Abstract

To increase sales, the management and sales department requires accurate, relevant and up-to-date information to support its function. Currently the amount of outstanding accounts receivables becomes one of the obstacles. So, credit limits criteria are applied as one of the effort to emphasis the outstanding receivables. Surely it will have an impact on increasing the effectiveness and efficiency of operations and ultimately will enhance the competitiveness. This research was done in three stages, data collection, analyzing the system requirements of current system to synergy with company?s target, and the results of needs analysis are developed into a new accounting information system with object-oriented approach and UML diagrams.

Abstract

It has been known that a group pile lateral capacity is smaller than the sum of each pile capacity composing the group. A reduction factor, also known as efficiency factor, is required to determine the effective lateral capacity of group piles. To the authors? knowledge, in most geotechnical text books, only the spacing of piles is considered in evaluating the pile group lateral capacity. No consideration on the effects of soil stiffness modulus and the total number of piles forming the group is taken into account. This research tried to investigate the influence of those factors by using geotechnical 3D finite element software, namely Plaxis 3D foundation. It is found that the bigger the number of piles in a group, the lower the efficiency factor is; the higher the soil stiffness modulus, the greater the efficiency is.

Abstract

The research aims to determine whether there is a relationship between the quality of sales information systems and user performance. The research method uses survey correlation techniques. Data are collected using a questionnaire previously calibrated to test the validity (product moment) and instrument reliability (Alpha Cronbach). The population used is users of information systems that are sales employees. There is a total sample of 20 people obtained, with Non-Probability Sampling that is saturated sampling / survey. Data analysis is performed using regression techniques of simple linear and simple correlation. Prior to analysis, test of analysis requirements need to be done, which are normality and homogeneity test. The results show acorrelation coefficient of 0:51 or 51% which means that there is a positive relationship on medium level between the Effectiveness of sales Information Systems with Users performance. The coefficient of determination is 0:26or 26%. This means that 26% of the variation in user performance can be explained by the variable Effectiveness of Sales Information Systems. Meanwhile, the remainder which is 74% consists of factors (variables), such as leadership style, work environment, salary and others. It can be concluded from this research that there is a positive correlation (relationship) at medium level which is significant between the Effectiveness of Sales Information System with User Performance, which means that the higher the level of effectiveness of Sales Information System is, the higher the level of user performance will be.

Abstract

Lean production has dramatically lifted the competitiveness of many manufacturing companies and the value they deliver to customers. This project examines the benefit of balancing process and workstation arrangement of dogbone damper in an order that maintains a smooth flow of materials and component through the process. The analysis begins from calculating takt value to establish the required rate of production. From here, any total cycle time exceeding takt time is called a bottleneck process and should become a target of the improvement. Next, arranging people and equipment into cells has great advantage in terms of achieving lean goals. One advantage of cells is the one-piece flow concept, which states that each product moves through the process one unit a time without sudden interruption, at a pace determined by the customer?s need.
