The wireless communication is the fastest-growing field of studies to enable humans to communicate with each other. Introducing a new blockchain architecture with big data analytics can be an enticing platform towards increasing connectivity performance throughout the smart cities. Blockchains can build a convenient mechanism allowing two devices to effectively transmit currency as well as data, to each other with a secure and reliable agreement. Smart cities provide an opportunity to connect people and places that use emerging technologies that help to improve urban planning and development. Smart cities can enhance public infrastructure and people's living experience. Presently, high-speed, intelligent, effective with several innovations, like low energy consumption, etc., seem to be accessible to interact together in the modern environment. By using the blockchain-based big data approach the physical devices are allowed to communicate securely with other physical devices in heterogeneous environments. This approach builds a new blockchain-based computing structure throughout the IoT technology configuration. This approach can examine blockchain technology to the underlying technology or maintains the IoT authentication reliable. This strengthens blockchain and cloud to develop an enabling IoT pervasive environment for secure communication among the physical objects
Currently, surveillance system and fire detector and surveillance system are developed separately. This paper focuses on development of smart surveillance system with fire prevention function. The existing fire detectors use smoke sensor, heat sensor that can just detect fire during growth stage. In this paper, RGB and CIE L*a*b algorithm are used to detect fire spark or flame using embedded camera. This system is developed to reduce loss of fire incident by detecting early stage fire (fire spark/flame) and notify the early stage to community, thus fast action can be taken. The developed system can be remotely controlled from anywhere that under IEEE standard connectivity. User can control the system from smartphone using Telegram application. The system can be installed in various type of premises such as factory, schools, private building and welfare center. The user will receive video and picture once the fire spark is detected. This module is important to handle false alarm case, where user can identify the incident using the received video/picture. Once confirmed, the user could decide to stop sirens if false alarm or notify authorized department for further action. These smart functions could help in reducing large damage since the authorized can be notified soon as fire spark occurs. The design, development and testing process will be discussed in this paper.Currently, surveillance system and fire detector and surveillance system are developed separately.

Advanced material such as fibre reinforced polymer (FRP) composite has been known for its lightweight characteristics. However, the performance of the material compare to metal always debatable. Therefore in this paper, it is comparing metal structure used as safety device in automobile with kenaf FRP composite structure. For the composite structure, taper cross-section has been chosen while the kenaf fibre was used as the main constituent and reinforced by epoxy thermoset. As a result, the composite structure able to obtain higher specific energy absorption (SEA) but lower energy absorbed compare to metal
Gedi (Abelmoschus manihot L.) is a tropical plant in the Malvacea family that is used as food and medicinal/herbal plant? This shrub can be found in Sulawesi, Maluku, Nusa Tenggara Barat dan Papua. The objective of this study was to determine the parameters to obtain an optimal extraction yield. As parts of ultrasonic extraction method, the parameters tested were ratios of dried Gedi leaf powder to ethanol and time of sonication. Gedi leaves from North Sulawesi was dried in an oven at 70oC for five hours and followed by grinding and sieving with 40-mesh siever. The first phase of the study was testing different solution ratios (m/v) of 1:10, 1:20, 1:30, 1:40, and 1:50 at a constant time of extraction of 30 minutes. The second phase was varying the time of sonication at 5, 10, 15, 20, and 30 minutes at the constant solution ratio of 1:40 (m/v). Throughout the study, the ultrasonic wavelength was set at 40 kHz and the temperature on the water bath for concentrating the Gedi leaf extract was set at 50 - 60oC. The optimal yields from both phases were 9.866% for the parameters of 1:40 (m/v) ratio and 30-minute sonication. Further analyses of Gedi leaf extract produced antioxidant effectiveness of 86.77% and phenolic content of 24.34 𝜇g/mg
Pedestrian safety becomes one of the serious problems in transportation systems. As the number of vehicles is growing, the levels of traffic accidents have increased significantly, Vehicle and pedestrian collisions often result in fatality to the vulnerable road users. This study aimed to review and analyses literature related to vehicle-to-pedestrian communication and classified the existing technology for Vehicle to pedestrian communication. The factors that were considered to improve understanding of the field’s various contextual aspects in published studies and characteristics were substantial analysis that confronted researchers and proposes a new direction for pedestrian safety to enhance this vital research area. We systematically searched all articles about vehicle to pedestrian communication in three main databases: Science Direct, Web of Science and IEEE Explore from 2008 to 2020. These indices were considered to be sufficiently extensive to encompass our field of literature. Based on our inclusion and exclusion criteria, 56 articles were selected. Most studies (29/56) focused on the development system, a number of papers (20/56) covered the study conduct on analysis, evaluation, and comparison, few papers (4/56) presented survey and overview studies. The last smallest portion (3/56) of papers study framework systems for V2P communication. Vehicle-to-pedestrian communication, which is a field requiring automated solutions, tools, and methods, entails the ability to facilitate detection or even prediction. Many studies have been performed on the detection and enhance data exchange of V2P to promote pedestrian safety. The research area's vehicle-to-pedestrian communication vary, but they are all equally dynamic. We expect this systematic review to help emphasize current research opportunities and thus extend and create additional research fields. A proposed research methodology as a new direction is provided to solve the gaps identified in the analysis. This methodology consists of four phases; Investigation Phase, design a framework for the pedestrian safety system, Study and Analysis, and evaluation phase. However, research areas on V2P communication with the scope of data exchange are varied. This systematic review is expected to open opportunities for researchers and encourage them to work on the identified gaps.
