The main focus of the research is excess inventory and motion waste which commonly occur in warehouse and production floor. This research is carried out to minimize the average level and eliminate unnecessary motions, with consideration of electronic pull and traceability system characteristics. Product X, the highest-selling product, is the object of this research. To identify the current condition, the current state Value Stream Mapping (VSM) is developed as the basis to arrange improvement plan to minimize the wastes. Safety stock is determined through average and maximum consumption difference; and reorder point is determined to comply with pull approach. Average inventory level is calculated using continuous review method. The simulation was conducted and it was shown that 8.29 minutes is the maximum lateness. Thus, safety stock and reorder point are adjusted accordingly to anticipate stockout due to lateness. The improvement of process cycle efficiency is shown to increase from 4.1 % to 5.1 % as projected in future state VSM.

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.

The purpose of this study is to develop a decision support system to support supplier selection process in PT Guna Elektro and also to develop a system that could provide alternatives to the selection of the best suppliers. The methodologies used in this study are analysis, design, and literature study. Analysis will be done by conducting a survey about the current company system, conducting interviews with system users, and then analyzing the survey results. The literature study is conducted by searching reference sources related to the study while the design is conducted by designing a data management subsystem, model, knowledge base, and user interface. The result on the development of the decision support system application can be used to select the most appropriate supplier which are suitable with the criteria required. The developed decision support system helps support the decision making process for supplier selection.

Bono tidal current leads to silting of the river estuary. The impact is a change in river line of Muda Island due to erosion and deposition. One alternative construction to overcome such this erosion problem of isGeotube, a construction system that combines geosynthetic material for blanket and sand slurry material for filler. Analysis is performed to ensure the system is feasible through the use of Geocops software to determine the type of suitable geosynthetic material and other parameters such as pump pressure. Another analytical calculation performed is the calculation of the stability of global construction through the use of Slope/W software and the approximate amount of consolidation decrease occurred using one-dimensional consolidation theory, published by Terzaghi. This article also presents the process of field implementation including various obstacles encountered and the solutions. From the results of the analysis and the field implementation, it can be concluded that the use of Geotube system on this project provides satisfactory results and can be relied upon as an alternative construction of erosion problems.

Knowledge management application on the internet keeps growing. It happens because the Internet offers new opportunities to use the knowledge assets, defines and spreads type of new knowledge assets, even to outside the organization. On the internet, appear social media that enable internet-based knowledge sharing system. As we know social media is not something new and has undergone many changes that allow for more interactive interaction and much greater number of users now. The research results showes that knowledge management and social media have nearly similar components. This allows the role of social media on the knowledge management application, such as collaboration tools coming with a clear business purpose.

Book as a learning method is less effective and interactive since it can not deliver motion animation. Thus, a more interactive learning method is needed to have a better learning process. The goal of the research is developing an application that provides easiness for students in learning algorithm by combining computerassited instruction (CAI) and internet technology. On the development phase, the research methodo uses fact finding by a survey to students who are or have been learning algorithm and a literature study, and also waterfall method for software development. The research output is a CAI application for learning algorithminteractively. The developed application is interactive for learning process and able to help students in deepen algorithm topics.

Research method used is through literature study, interviews and observation. Audit method used is the method of auditing around the computer. Analysis was performed by analyzing the findings of problems, risks, and recommendations on the findings of the problem. After doing research, we conclude that there are still some weaknesses in management control and application control. But companies should be more focus on the weaknesses inherent limitations in controlling the application and control the output. Based on these findings, suggested that the company to rectify existing weaknesses and enhance control over payroll information system.

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.
