Abstract

Current technological developments, especially in the IT field have been developing very rapidly. Now, by using the internet, we can do anything even though we are far apart. One technology that utilizes the internet is a monitoring system or commonly called the Internet of Things. At present, the number of users of electricity is increasing from year to year. One of the services currently available is postpaid electricity service. However, in the distribution of electricity usage data is still done conventionally and data retrieval is done in an uncertain time span. From these problems, data collection and transmission can be carried out in a more efficient way by monitoring electricity usage in realtime on a publish-subscribe-based MQTT protocol. The monitoring system that is run has a small delay, which is 11 ms. In addition, the MQTT protocol can also be run on limited network conditions, namely on network conditions that have low bandwidth. At 32KBps the average delay is 17 ms. So the system can be run on a limited network.

Abstract

Motor vehichle is a kind of transportation mode that are popular among people in Indonesia. Annually the increase in number of drivers is growing rapidly. Safety always comes first in driving for the sake of avoiding accidents. Accidents occur because of many driver's negligence factors such as drowsy when driving, bad facilities and infrastructure, using device that takes away your attention from the road and ignorant of the speed limit sign. For sake of helping the drivers to manage their speed according to the sign, it is needed of a system that can help remind the driver of the existence of the sign. Before fulfilling the task of reminding the drivers surely the system would need to be able to detect and recognize the speed sign. In this research the writer would want to propose the usage of Circle Hough Transform as the method of detection dan Convolutional Neural Network as the method of recognition with the purpose of knowing the performance of both method in doing their task. Both of the methods are in the field of study of Digital Image Processing and Machine Learning respectively that is well-known with its big computational need. The big computational need is the reason minicomputer Raspberry Pi is chosen as the base processing unit of the system compared to microcontroller. The result of testing for detection and recognition are 61.3% and 75% respectively. Looking from the results the methods that are proposed are not great but the writer believe that for the future research there is still room for improvement of the Circle Hough Transform and Convolutional Neural Network.

Abstract

Twitter is popular social media in great demand because it provides information needed by many internet users. Such information can be in the form of opinions, questions or review of a product's good or bad. Diverse smartphone product reviews make it difficult for companies to know people's interests and opinions on the smartphone product. To find a solution for this problem, sentiment analysis system is needed on tweets about smartphone products. This research conducted a sentiment analysis with the K-Nearest Neighbor (textual) method to carry out the classification process and add weighting features to the number of likes (non-textual). The result of combining intellectual and non-textual weighting with certain constants is α constans and β constans will produce a class of positive and negative sentiments. The data was used is taken from Twitter in the form 300 data tweets of smartphone product reviews.

Abstract

The existing IoT middleware has been developed to answer the challenge of syntactical interoperability by creating a gateway so that it can communicate through the CoAP, MQTT and WebSocket protocols. However, the middleware can accept data from anywhere and various nodes that are not entitled to connect to the middleware. So we need an additional mechanism on the IoT middleware to authenticate the node that will communicate. Authentication is a guarantee that all involved in system communication are valid entities. Therefore, in this research, the development of IoT middleware is done by adding the JSON Web Token (JWT) authentication mechanism. JWT is a token that represents a concise message called claims and is protected by a digital signature, in addition, JWT tokens have an expiration time. JWT tokens are used because of their compact size so they can be sent via URL, query or header. Based on the test results, the authentication mechanism that is applied is able to authenticate the token sent by the node. The impact of applying the authentication mechanism to the IoT middleware causes the node to increase the time it takes to establish connections and publish or subscribe. Compared to IoT middleware without authentication, the average time difference generated is below 30 milliseconds.
