<![CDATA[Internet of Things (IoT) connecting sensors or devices that record physical observations of the environment and a variety of applications or other Internet services. Along with the increasing number and diversity of devices connected, there arises a problem called interoperability. One type of interoperability is syntactical interoperability, where the IoT should be able to connect all devices through various data protocols. Based on this problem, we proposed a middleware that capable of supporting interoperability by providing a multi-protocol gateway between COAP, MQTT, and WebSocket. This middleware is developed using event-based architecture by implementing publish-subscribe pattern. We also developed a system to test the performance of middleware in terms of success rate and delay delivery of data. The system consists of temperature and humidity sensors using COAP and MQTT as a publisher and web application using WebSocket as a subscriber. The results for data transmission, either from sensors or MQTT COAP has a success rate above 90%, the average delay delivery of data from sensors COAP and MQTT below 1 second, for packet loss rate varied between 0% - 25%. The interoperability testing has been done using Interoperability assessment methodology and found out that ours is qualified.]]>

<![CDATA[An Internet of Things (IoT) middleware can solve interoperability problem among “things” in IoT infrastructure by collecting data. However, the sensor nodes’ data that is collected by the middleware cannot be directly delivered to cloud applications since the sensor nodes and the middleware are located in intranet. A solution to this problem is an Internet Gateway Device (IGD) that retrieves data from the middleware in intranet then forwards them to cloud applications in the internet. In this study, an IGD based on cellular network is proposed to provide wide-coverage internet connectivity. Two test scenarios were conducted to measure delay and throughput between the IGD and the cloud application; using data from DHT22 sensor and image sensor respectively. The results of the first test scenario using DHT22 sensor show that the average delay is under 5 seconds and the maximum throughput is 120 bps, while the second one using image sensor concludes that the average delay is 595 seconds and the maximum throughput is 909 bps.]]>

<![CDATA[One solution for interoperability issue in IoT is a middleware which is competent on resolving the problems of syntactical, semantic, and network interoperability. In previous study, a middleware capable of addressing semantic and syntactical interoperability challenges has been developed, yet has not responded to network interoperability matter. In this paper we continue our previous research by adding BLE and 6LoWPAN features to the middleware's communication media, so it may communicate with various devices. Interoperability test results show that the middleware is capable of responding to network interoperability challenges and able to receive data from multiple nodes simultaneously.]]>

<![CDATA[Untuk memenuhi kebutuhan masyarakat akan ketersediaan informasi, maka dikembangkan teknologi dengan nama push notification. Teknologi push notification adalah teknologi yang memungkinkan sebuah perangkat (client) mendapatkan informasi berupa notifikasi yang dikirimkan oleh penyedia informasi (server) secara otomatis. Pada umumnya mekanisme pengiriman notifikasi dari server ke client menggunakan push service yang berdiri sendiri (broker) dan menggunakan protokol Hypertext Transfer Protocol (HTTP). Namun masih sering terjadi keterlambatan pengiriman notifikasi dengan menggunakan mekanisme pengiriman tersebut. Broker yang membatasi antar server dan client dalam mekanisme pengiriman notifikasi dinilai tidak efisien. Diperlukan pengembangan lebih lanjut untuk mengatasi dua masalah tersebut. Penelitian ini akan mengembangkan mekanisme pengiriman notifikasi dengan push notification yang akan diimplementasikan dengan menggunakan protokol websocket dan implementasi broker kedalam server. Hasil pengembangan pada penelitian memiliki jumlah maksimal client yang dapat terhubung dengan server sebanyak 1015 client serta rata-rata delay yang didapat dari pengujian pengiriman notifikasi secara massal, pengiriman notifikasi dengan ukuran yang berbeda, dan pengiriman notifikasi menggunakan bandwidth yang berbeda.]]>

<![CDATA[Internet of Things (IoT) is a system where its contained devices are interconnected which makes it possible to exchange information or data via Internet. Middleware is an intermediary system between hardware and software which contained in IoT system. In the previous research, middleware was developed to overcome interoperability problem by providing multi-protocol gateway for CoAP MQTT and Websocket. There are several aspects to test middleware such as integration, interoperability, scalability, real time performance, and security. In the previous research, integration testing was performed to test the suitability of middleware with its functional requirements and interoperability testing in order to know the level of middleware interoperability, therefore in this research a test performed with other aspects which is performance and scalability. The results of performance and scalability analysis are average CPU usage of CoAP protocol was 0.68%, MQTT 0.60% and CoAP MQTT 1.21%, average Memory usage of CoAP was 5-7%, MQTT 8-9%, and CoAP MQTT 10-12%. The average delay time of sending data from nodeMCU to middleware for CoAP and MQTT is 3 seconds. The average data transmission delay time from nodeMCU to middleware with packet loss is varied between 0% - 75%. The ability of middleware to overcome publish or subscibe in one second with 100 to 1000 clients grows as the number of clients increases.]]>

<![CDATA[To create an Android application, developers need to consider things other than security, such as application performance, because Android itself as a mobile device inherently has limited resources so that efforts to improve the performance of applications developed specifically for the Android platform needs to be done. Questions on developer forums such as Stackoverflow on which algorithms are performing better on Android platforms are emerging, to answer those questions there will be a performance comparison between two well-known and popularly used cryptographic algorithms, AES and Blowfish. The study chose two popular symmetric cryptography algorithms that are used: Advanced Encryption Standard (AES) algorithms and Blowfish algorithms to compare performance on the Android operating system. The data used derived from the generator data based on certain rules. Comparison of performance will be done with 3 parameters, namely: data length, key length, and differences in processor architecture. Testing each data is done 20 times to improve the accuracy of algorithmic performance. The test results show that the Blowfish algorithm has better encryption and decryption performance than the AES algorithm on testing of data length and key length, on testing of Intel AES processor is superior to 0.3-0.4 ms faster while on ARM processor Blowfish is faster by 0.2 Ms.]]>

<![CDATA[Access log record all requests that processed by the web server. Access log is a file that contains an important line about website visitors. However, access log data is still in the form of raw data so it is difficult to read and analyzed to get activity information of website visitors on a website. In this research, the solution offered is to make a web-based application that can be used as a tool for knowing visitors' activity information on a website using access log data from an apache server. The data of access log will be parsed and the result data of the parsed access log will be saved into the MySQL database. Then this data is filtered by using a specific query in MySQL for later visualized by the application to the form of graphics or tables for further analysis. Based on the results of this study, Access Log Visualizer has been able to parse access logs by using regex and retrieve the access log data from the database by using MySQL query and display the visualization of the data access log, so that this system can process access log data for knowing activity information of website visitors on a website.]]>
