Abstract

Based on data from the Central Statistics Agency, motorcycle accidents are the most common accidents and many contribute to the death rate in traffic accidents. Some cases of deaths in motorcycle accidents are caused by riders not wearing helmets. Monitoring via CCTV video has been done but it takes a long time so we need another solution to be more effective. Some techniques have been carried out including detection of the use of helmets on motorcyclists by using digital image processing. Some previous studies on these cases experienced obstacles such as overlapping images in the identification process. This study aims to develop a detection method that focuses on the segmentation stage to produce a better segmentation image. The method used in this study is Automatic RoI and Active Contour at the segmentation stage which is then classified using the Multilayer Perceptron classifier. The results obtained give an accuracy value of 72.97%, a sensitivity of 76.19% and a specificity of 68.75%.

Abstract

In order to enhance the user experience of virtual reality (VR) devices, VR multi-user environments and wireless connections must support as the latest generation of VRdevices. Wireless network-based wireless communication devices (WLANs) are popular consumer devices with high throughput and low cost using incompatible bands. However, the use of WLANs can cause packet delivery delays, due to their distributed nature when accessing channels. In this paper, we carefully discuss wireless VR via WLAN, and we request an efficient wireless multiuser VR communication architecture, as well as providing communication for VR. Because the architecture proposed in this paper uses many WLAN standards, based on the characteristics of each VR traffic chain, it is agreed that it supports the efficient sending of massive uplink data generated by several VR devices, and provides adequate frame rates and video control frames. rate for high-quality VR services. We conduct evaluations that are supported to improve exceptional applications than are supported

Abstract

E-Tourism is a digital platform that connects all tourism stakeholders, and integrates all tourism activities and makes it easy for all travelers to explore tourism charms by accessing applications without being tied to places and times. In Indonesia especially in Bali the development of E-Tourism can be very good. Many sites are available on the internet to be a medium of information and tourist accommodations booking media. In addition, many government and private sites also play a role in the process of providing tourist information, but these sites can be said to be static and simple. These providers only provide text information without prioritizing responsiveness and interactivity to the users.Responsiveness and interactivity are two issues in today's tourism sites. The existing tourism sites in Indonesia are still lacking in responding to the needs or questions of the users and also the interactive functions on the site are felt to be less than satisfactory. Users are only provided an information in the form of photographs and writings about a tourist attraction. Users never know where places can be visited with approximate time, location recommendations, routes and schedules that adjust to user needs. Refers to the problems,we develop an application that able to give recommendation and guidance of tour in Bali area.The system is made on the main needs that have been defined that the system is able to provide travel recommendations. After testing with black box model, the result of the system has been able to meet the needs of the user and provide travel recommendations in accordance with the needs of the user where the travel time-limited, category of place, place of the beginning of the journey and the final place has been fulfilled. The system has given the suitable recommendations based on the criteria that the user wants.

Abstract

The public transportation model which is currently widely used by people who live in Jakarta, Bogor, Depok, Tangerang and Bekasi (JABODETABEK) is the Commuter-Line Electric Train (KRL). According to online media sources(http://Kompas.com 2 December 2015), currently, the JABODETABEK Commuter-Line KRL can carry 900,000 passengers every day. Anti Lock Braking System (ABS) is a braking system that maintains the position of the wheels and the road to prevent tire/wheel slip. Anti Lock Braking System was first used or applied to aircraft. Vehicles that are not equipped with the Anti-lock Braking System must be updated. The driver makes optimal braking to prevent slip between the wheels and the road or rail so that the vehicle stops perfectly. In this paper, we will use fuzzy inference logic to support an Anti-lock Braking System (ABS). Fuzzy inference is a logical method because when determining variables in the fuzzy method, the variable must have an International Standard (SI).

Abstract

The garbage crusher is one of the tools that is considered to have a high level of effectiveness in overcoming the problem of garbage in the river around DKI Jakarta. However, the dredging tool that is currently available is still moving manually in operation, which results in scheduling human resources that are less than optimal in every operation. This requires a garbage dredger whose operation can work automatically so that the scheduling of human resources in the operation of the garbage crusher is optimal. In this research, automatic garbage scrapers will be simulated using a Fuzzy Inference System. Simulation in the form of knowledge making on decisions that will later be on automatic garbage scrapers using a fuzzy inference system.
