Abstrak Perangkat IoT yang diimlementasi pada banyak tempat dapat mengalami perubahan berupa update firmware. Update firmware pada perangkat IoT biasanya dilakukan dengan  mengambil perangkat IoT, lalu menghubungkan ke komputer mengunakan komunikasi serial melalui kabel usb to micro usb, selanjutnya melakukan update firmware pada perangkat IoT dan mengembalikan perangkat IoT ke tempat. Jika sistem pada perangkat IoT sudah dapat berkomunikasi melalui antar muka jaringan, tidak perlu lagi mengunakan kabel usb to micro usb, karena bisa dimanfaatkan over the air update firmware mengunaka antar muka jaringan pada perangkat IoT. Over the air update firmware adalah memuat firmware hasil build dari arduino ide pada perangkat IoT mengunakan antar muka jaringan Wi-Fi, pada penelitian ini perangkat IoT mengunakan mikrokontroler esp8266 12E. Untuk melakukan update firmware perangkat IoT digunakan protokol MQTT untuk menjembatani antara aplikasi berbasis website sebagai interface penguna untuk PUBLISH file firmware ke perangkat IoT. Hasil dari implementasi Aplikasi berbasis website untuk over the air update firmware pada perangkat IoT dengan protokol MQTT, dalam 10 kali pengujian pengiriman file firmware perangkat IoT mengunakan masing-masing QoS 0, QoS 1, dan QoS 2, didapatkan hasil QoS 2 lebih direkomendasikan untuk digunakan mengirim file firmware dengan keberhasilan update firmware QoS 0 = 50 %, QoS 1 = 70% dan QoS 2 = 80% dari 10 kali percobaan pengirman file firmware pada perangkat IoT.Abstract IoT devices that are implemented in many places can experience changes in the form of firmware updates. Firmware update on an IoT device is usually done by taking an IoT device, then connecting to the computer using serial communication via a usb to micro usb cable, then updating the firmware on the IoT device and returning the IoT device to its place. If the system on the IoT device is able to communicate through a network interface, there is no need to use a USB to Micro USB cable, because it can be utilized over the air firmware update using the network interface on the IoT device. Over the air firmware update is to load the firmware build from Arduino Idea on an IoT device using the Wi-Fi network interface, in this study the IoT device uses the ES8266 12E microcontroller. To update the firmware of the IoT device the MQTT protocol is used to bridge the website-based application as a user interface for PUBLISH firmware files to the IoT device. The results of the implementation of a website-based application for over the air firmware update on IoT devices with the MQTT protocol, in 10 times testing the sending of IoT device firmware files using each of QoS 0, QoS 1, and QoS 2, the results obtained QoS 2 are more recommended for use sending firmware files with successful firmware update QoS 0 = 50%, QoS 1 = 70% and QoS 2 = 80% of 10 attempts to test the firmware file on an IoT device.

This paper introduced to develop and implementation of PC based controller for humanoid robot using digital potentiometer. The main objective in this paper is to develop and implement the joystick controller by using a digital potentiometer circuit board that be able to control the humanoid robot movement. The Arduino board and digital potentiometer will be integrated by connecting both pins in between wiper, W pin and ground, GND to the DB9 pins of remote control platform, which is TX and RX pins respectively. Humanoid robot as known as TOMY i-SOBOT is used as a preferred model due to wide usage in many applications. A digital potentiometer will be transmitted the voltage and current value depend on the digital level through serial communication to give the instruction for humanoid robot movement. The humanoid movement based on Guided User Interface (GUI) where the user give a commands by pressing the button on the GUI such as turn left, right, forward, and reverse. The results show that the humanoid movement able to control based on the voltage and current in a digital potentiometers value.

The internet is widely used in daily life, of course, also be applied in agriculture. This paper is focus on the technology of ZigBee and serial communication. The ZigBee communication module transfers the data from greenhouse to the monitoring system. Growers can get the data timely, and according to the received data to control greenhouse environment. The monitor computer program is based on VB.NET. ZigBee module gets the data from sensor, through serial ports the information is transferred to the monitor computer. The monitoring software stores the data and displays it on the user interface. If the data beyond the threshold value, the system will give an alarm sounds.

The ability to securely join IoT Devices to Wi-Fi networks is an on-going area of research. This paper describes how Nasrin & Radcliffe's theoretical “novel minimalist IoT network joining protocol” has been mapped to real world hardware and implemented using the Android operating system. For the first time the theory is proven to be practically viable but it is also shown that the user interface is not sufficiently simple for the everyday user. This paper proposes and implements a new user interface paradigm that dramatically simplifies the process and makes the joining process accessible to a much larger range of users.  For intensely cost sensitive applications an alternative process is proposed that has the possibility of even further simplifying the user experience. Finally the compatibility of the protocol with a  variety of operating systems is assessed.

Remote on-line electron microscopy is rapidly becoming more available as improvements continue to be developed in the software and hardware of interfaces and networks. Scanning electron microscopes have been driven remotely across both wide and local area networks. Initial implementations with transmission electron microscopes have targeted unique facilities like an advanced analytical electron microscope, a biological 3-D IVEM and a HVEM capable of in situ materials science applications. As implementations of on-line transmission electron microscopy become more widespread, it is essential that suitable standards be developed and followed. Two such standards have been proposed for a high-level protocol language for on-line access, and we have proposed a rational graphical user interface. The user interface we present here is based on experience gained with a full-function materials science application providing users of the National Center for Electron Microscopy with remote on-line access to a 1.5MeV Kratos EM-1500 in situ high-voltage transmission electron microscope via existing wide area networks. We have developed and implemented, and are continuing to refine, a set of tools, protocols, and interfaces to run the Kratos EM-1500 on-line for collaborative research. Computer tools for capturing and manipulating real-time video signals are integrated into a standardized user interface that may be used for remote access to any transmission electron microscope equipped with a suitable control computer.
