<h1 align="center">Abstrak</h1><p><em>Pengolahan data kendaraan satuan jajaran Kostrad yang dilakukan oleh satuan Palkostrad dalam penyajian informasi datanya masih dalam bentuk konvensional meskipun telah menggunakan media komputerisasi yaitu dalam bentuk word dan excel, hal ini menjadi salah satu penyebab terjadinya overlaping data. Selain itu mobilitas yang tinggi dari satuan Palkostrad dan belum memaksimalkan dalam penggunaan media informasi ini dapat dilihat masih adanya keterlambatan dalam penyajian informasi data Alutsista bidang kendaraan satuan jajaran Kostrad. Guna mempermudah dalam pengolahan informasi data kendaraan di satuan jajaran Kostrad, diperlukan suatu sistem informasi berbasis web dengan struktur database yang terintegrasi dengan baik. Untuk mengatasi overlaping data dan ketepatan dalam penyajian informasi data Alutsista bidang kendaraan satuan jajaran Kostrad maka perlu dilakukan perancangan dan pembangunan sistem informasi data Alutsista bidang kendaraan disatuan jajaran Kostrad yang berbasis web. Terkait dat-data yang diperlukan pada penelitian ini diperoleh melalui studi pustaka, wawancara dan pengumpulan dokumen. Hasil yang di peroleh dengan pengembangan sistem ini diharapkan dapat membantu memecahkan permasalahan yang ada pada penelitian ini.</em></p><p align="center"><strong><em>Abstract</em></strong></p><p><em>The data processing of Kostrad unit vehicles carried out by Palkostrad units in the presentation of data information is still in the conventional form even though it has used computerized media in the form of word and excel, this is one of the causes of data overlapping. In addition, the high mobility of the Palkostrad unit and not yet maximizing the use of this information media can be seen that there is still a delay in the presentation of information on the defense equipment data of the Kostrad unit vehicles. In order to facilitate the processing of vehicle data information in the Kostrad ranks, a web-based information system is needed with a well-integrated database structure. To overcome the overlapping of data and the accuracy in the presentation of data information on vehicle units in the Kostrad line, it is necessary to design and construct a vehicle information system for vehicle systems in the web-based Kostrad line. Related data needed in this study were obtained through literature study, interviews and document collection. The results obtained by developing this system are expected to help solve the problems that exist in this study.</em></p>

There is a risk that voice messages from in-vehicle information systems may cause a driver to be distracted while driving. To avoid such a risk the message systems need to be adapted to drivers' mental workload. Such adaptive systems deliver voice messages when drivers' mental workload is low and postpone the messages when the driver workload is high. It is important for the system to estimate the current driver workload from car sensors such as car speed, steering wheel angle, accelerator pedal position and so on. In order to find some relations between the driver's mental workload and the data from car sensors, a dual task experiment was conducted on a public road. In the experiment, participants performed a memory task while driving an experimental car. At the same time, the data from the car sensors were recorded. The correlation coefficients between the memory task performance and the data from car sensors showed that release of the accelerator pedal was the most significant indicator of workload. Based on these results a workload estimator was developed, which has been applied to a voice information delivery test system. The potential of a voice information system that adapts to the driver's mental workload was evaluated.

Vehicle information system is the data center of vehicle communication networks, for the sake of connecting the IPv6 host through IPv4 network area, a virtual network device (VND) in Linux embedded System is designed and implemented as a mid-layer module between the real device driver and internet protocol stack. The VND can establish a virtual tunnel between the vehicle information device and agent server. Both vehicle information device and agent server can support IPv4 and IPv6.Through the virtual tunnel, the agent server picked up the IPv6 packet which was built in IPv4 UDP data area, and transmit the IPv6 packets to the IPv6 remote server. So it works like a VPN device. The hardware platform of the vehicle gateway is based on ARM9, and the software is based on ARM-Linux. The instruction of hardware and software are as well as put forward.

This study compared driver acceptance of general icons to specific icons for In-Vehicle Information System (IVIS) devices. In the study, general and paired specific icons, along with two unrelated icons, were tested in both the general and specific driving scenarios. Subjects were asked to select: (1) one icon that most accurately described the driving scenario; and (2) one or more icons that would be acceptable for the driving scenario. The most accurate icon type selected by the subjects was strongly associated with the given scenario type, with the exception of collision avoidance. That is, when the driving scenario was described in general terms, subjects typically selected general icons as most accurately representing the scenario; when the driving scenario was described in specific terms, subjects typically selected specific icons as most accurately representing the scenario. In contrast to the icon accuracy, high acceptance levels were obtained for both general and specific icons regardless of the driving scenario description. Therefore, general icons are capable of meeting driver expectations and preferences for a broad range of IVIS messages. Recommendations for icon design are: (1) general icons should be used as long as they do not negatively impact driver acceptance or driver performance; and (2) for safety-related messages, specific icons will provide higher levels of driver acceptance than general icons.
