Abstract

This article discusses aout the knowledge management system implementation as growth tool at PT Intimap. The purpose of this study is to give solution to problems faced by PT Intimap, related to knowledge and the resources they own. Method used for the system development is the SDLC. Analysis shows that PT Intimap is a company with vast amount of knowledge. However, the knowledge has not been managed very carefully. Hence, there is a need to an integrated system, where all employees can put their knowledge and look for what they want to know within the system.

Abstract

English proficiency can be measured through several tests that are recognized internationally like TOEFL. To measure the English proficiency of ‘Binusians’ with TOEFL standards and provide rapid and credible test results, an program design of online English test application (ATBIO) is created by displaying a random question, in which every examinee gets different questions. Prior to the design, first performed profile analysis of the questions in the TOEFL test held by Binus University Language Center. Following is the design of the program using standard UML 2.0 notation. Furthermore, the author submitted the draft to be built by the program developers using java script or ASP. With credible, fast and accurate results of ATBIO, it is expected that people, departments or organizations concerned with these test results can immediately make decisions and take necessary actions.

Abstract

Slope – deflection equation method is an analysis method to solve statically indeterminate structure. This method is a simple technique to analyze continuous beam, either prismatic or non prismatic. The technique for analyzing non prismatic beam is based on the prismatic beam concept, but with the introduce of some modification coefficient. These coefficients are available in some textbook discussing about structural analysis. This research has an objective to compare the analysis result of a continuous non prismatic beam, with slope – deflection equation method, and result from a structural analysis program (i.e. SAP 2000 v.11.00). The internal moment at the joints produced from this two method will be compared each other. The results show that there is a small difference resulted in internal moment, obtained from hand calculation with slope – deflection method and from software output. The differences resulted from this two techniques are 2 up to 6%. Based on this result it can be stated that slope-deflection method can be used to analyze statically indeterminate nonprismatic beam with some modification factors. The result obtained is nearly the same with one obtained from commercial softwares.

Abstract

To maintain a trading business in the strict competition a management supported by appropriate business strategy is required. Utilization of an information system that supports decision-making is needed to improve performance as well as support for all lines of business. Therefore, a research is conducted that specifically aims at the development of decision support systems for small and medium enterprises (SMEs). The basic method for building the system is the Herbert Simon's four-stage decision-making approach: intelligence, design, choice and implementation. Following is the building of data management subsystem, management subsystem model and user interface subsystem. The development of this system results in a decision support system that can improve the performance of all business lines complemented with support information for decision making.

Abstract

That optic business is increasingly mushrooming followed by a decrease in market share, forces Optik XYZ to have competent management strategies to achieve a strong position in competing in similar industry. Therefore a study was conducted to provide a structured and systematic analysis of management strategies required by Optik XYZ. Stages of study were initiated by data collection from interviews, literature studies and field studies, followed by qualitative and quantitative analysis and implementation of management strategies. The study generated a formulation of management strategy proper for Optik XYZ. Management strategies formulated in this study can help carrying out the company's activities in decision making, so that the business processes run optimally.

Abstract

This study aims to analyze and design a geographic information system as a tool for traffic flow monitoring and regulation for the Traffic Management Center Polda Metro Jaya. Data was collected through field studies relating to the engineering of software and hardware. Interviews were also conducted to the relevant parties. Then it is proceeded with systems analysis and design methods. This system succeeded in helping the Traffic Management Center to find out the points which are prone to cause congestion, so that it can quickly obtain the traffic flow information.

Abstract

The architecture curriculum in formal education is necessary to be redefined in order to adapt to computing technology to obtain its good values. CAAD is added to architecture learning with no settled framework; relying on practical experience of lecturers. This reminds of how important the adaptation to the theories and science of architecture that evolved with the advent of digital media is. Therefore, the methodology and teaching approach systems are need to be reviewed, with the help of architects, professionals and the authority to fix the narrow perception of digital architecture. This article is a summary of several earlier studies on the influence of information technology on the education of architecture lately. It is expected that in the future this article may be useful as a theoretical basis for the course Computational Design in Architecture Architecture I at Bina Nusantara University.

Abstract

Changes in land use due to the rapid growth of building construction leads to an increase in direct runoff, as well as declining water that seeped into the ground. Consequently, water distribution happens to be unequal of between the rainy and dry seasons. This phenomenon also occurs in the area of Kijang Campus - Bina Nusantara University which always comes up with puddles even though the rain falls with only a short duration. In this research the rainfall on the Kijang Campus - Bina Nusantara University is assessed based on the rainfall data record to obtain the rainfall intensity of various periods. Field survey is conducted to determine the existing infiltration capacity (with / without bio pore holes) and on-site. It is concluded based on the research results using Horton method that the soil on the Kijang Campus - Bina Nusantara University is earth embankment that has the infiltration capacity ranging between 0.0867 - 0.2165 m3/hr. This illustrates that the soil infiltration capacity is relatively small and thus requires the installation of bio pore holes with distance by 0.5 meters.

Abstract

Vacuum preloading is an alternative method to improve water-saturated soft clay by accelerating the consolidation process. A trial using GVS system was done at Pantai Indah Kapuk residence, Jakarta to investigate the system reliability. Monitoring equipments used include settlement plate to measure the consolidation decrease, piezometer to measure pore water tension, inklinometer to identify the soil direction and lateral movement during the vacuum preloading process, and manometer to measure the vacuum pump pressure. Analytical calculations to estimate the consolidation decrease is done using one-dimensional consolidation theory of Terzaghi. Besides, a numerical analysis is performed by element method up to Plaxis software application. Meanwhile, the monitoring results are achieved using Asaoka theory that estimates the achieved degree of reduction and consolidation. The monitoring results and theoretical analysis indicate that the GVS system included in the vacuum preloading method is quite reliable as an alternative method of consolidation acceleration of water-saturated soft clay.

Abstract

Writing notes on paper is fun because we can simply write whatever we want on it. Writing notes in the digital media is also advantageous for it can be shared directly. If we can combine the two functions, it will be more profitable. Therefore, the author wants to combine the benefits of writing as you wish like as on paper with contemporary digital writing. Somehow, writing using PC cannot be done at any time due to the needs of both electrical connection and space availabilty. Therefore, Smartphone or tablet is the right choice because it is not tied to two needs. The Smartphone to be selected is the one built with android platform for ease of note transfer compared to other platforms.
