Abstract

TV broadcast systems are migrating from analogue to digital broadcasting system. Some countries in the world have completed this migration since a few years ago. America decided to stop broadcasting analog television in 2009. In Asia, Singapore launched this technology in 2004 and Malaysia implemented in 2006 (Depkominfo, 2009). With so many countries are migrating to digital broadcasting system, there are many business models that can be referred for organizing digital television broadcasts. In this writing, several business models that are used in the world will be reviewed and analyzed and the results can be a reference to determine the appropriate business model according to the organizers.

Abstract

Analysis and design of information system in PT. Maju Jaya Mulya is aimed to identify the organization needs in controlling and managing the data and information of operational transaction. They will be used as a base for developing a new integrated system that can meet company needs and to face the rivalry from the competitors. The activity in analysis and design is focused in production, inventory management and purchasing activities, as the main business of the company. The analysis and design of the company’s needs will be documented by using unified modeling language. With this information system, there is an expectation that this system will ease the company in doing their activity in production, inventory management and purchasing. This system will also minimize the data lost and human error, which is usually caused by the manual process and storage data of transactional data.

Abstract

The development of information technology creates a new way of many aspects in life. Innovations in this technology affect toward business environment, especially banking, which makes the business run dynamically. All of the transaction of a bank will be processed easily with the presence of computer. A bank needs all of the changes in order to compete with competitors, and that includes changes in information technology. The more expanding and complex facilities applied in a bank, the more complex and diverse technology adopted by a bank. The implementation of technology information in banking is not simple, it needs a long term planning and maintenance system so that all of the technology information facilities could run well and give a significant impact. Technology monitoring or benchmarking is one of the options that is taken by a bank to maintain its existence in facing the tight competition. To create technology innovation in banking need a monitoring technology method that is named TW-CI. This method is used to fulfill business needs in facing a competition to get and choose information that can be used to support a decision, so that the innovation applied by a bank is efficient and finally give an added value and also create entanglement between a bank and its consumer.

Abstract

Creating autonomous vehicle that can drive without a driver is a dream of the researchers who see the application of such a system will be needed in the future. Realizing such a system requires a dynamic model of the vehicle. It may be obtained by analytical method using dynamic equations. However, this way is rather difficult to do, especially in modeling the non-linear factors caused by tires, suspension, road conditions, etc. This study, in order to avoid difficulties in the analytical method, used artificial neural networks to model the dynamic system of the autonomous vehicle. It utilized data input from the camera sensor and vehicle speed.

Abstract

In the operating process of electrical energy, economic planning is the main goal to be achieved. The goal of economic dispatch problem is determining the combination of optimal power distribution to a number of operating generator units so that the electricity demand in a certain area is fulfilled without ignoring the constraints that exist, so it is obtained a minimum total generation cost. Optimization method that is used is the Gaussian Particle Swarm Optimization (GPSO), while for the validation of the results, the obtained solution with the GPSO will be compared with the solution obtained by mathematical methods Extended Lagrange Multiplier (ELM) or the Lagrange multiplier method which its functions are expanded. The solution that is calculated is generation output in Megawatt of 23 thermal generating units system in Mahakam, East Kalimantan, which had a total cost of optimal generating (minimum).

Abstract

In general automotive development, especially car, PT Astra Daihatsu Motor (ADM) continuously improves quality and service to supply vehicles in Indonesia. To support the improvement of quality and service, PT ADM continues to improve technology-based system to assist in providing vehicle parts of production process requirements. Therefore Purchasing division is very important in this process. Besides, supplier is a very important role in making and supplying parts for the company. PT ADM has a new system used to improve bidding process. Based on the discussion, price was not the only thing significant. There were other things to consider, especially in selecting the right supplier.  Realizing the system does not cover all areas, therefore, it needs Decision Support System with AHP method to filter suppliers. So that, the company will automatically have good supplier. At least, the supplier meets company standard, especially purchasing department. This research concludes that using AHP Method is very effective for filtering supplier so that the company can make sure that only capable supplier or supplier which meets company standard may join the tender to supply the goods or parts. This paper combined AHP Methodology as the first selection using pairwise scoring and Analysis Sensitivity Methodology used to take decision which supplier is in line with project requirements.
