Energi matahari adalah sumber energi terbesar yang ada di muka bumi ini. Panel surya merupakan sebuah peranti elektronik yang dapat memanfaatkan energi dari sinar matahari untuk dikonversi menjadi energi listrik. Semakin besar permukaan panel surya tersinari cahaya matahari, maka energi listrik yang dihasilkan lebih besar. Makalah ini memaparkan rancang bangun penjejak matahari menggunakan kamera sebagai pendeteksi posisi matahari dengan modul Raspberry pi sebagai kendali untuk pengolahan citra. Pergerakan penjejak posisi matahari ini menggunakan dua aksis, yaitu pitch dan roll. Aktuator yang digunakan untuk mengikuti posisi matahari adalah dua buah motor DC dengan jenis linier aktuator. Hasil dari pengujian menunjukan bahwa kamera dapat mendeteksi titik cahaya menggunakan pengolahan citra pada modul Raspberry pi. Kemudian rangka penjejak sinar matahari berhasil menuju posisi yang diinginkan yaitu pada titik tengah kamera dengan menggerakan dua buah linier aktuator melalui driver motor.

KRSBI Wheeled is One of the competitions on the Indonesian Robot Contest,. It is a football match that plays 3 robot full autonomous versus other teams. The robot uses a drive in the form of wheels that are controlled in such a way, to be able to do the work the robot uses a camera sensor mounted on the front of the robot, while for movement in the paper author uses 3 omni wheel so the robot can move in all directions to make it easier towards the ball object. For the purposes of image processing and input and output processing the author uses a Single Board Computer Raspberry PI 3 are programmed using the Python programming language with OpenCV image processing library, to optimize the work of Single Board Computer(SBC) Raspberry PI 3 Mini PC assisted by the Microcontroller Arduino Mega 2560. Both devices are connected serially via the USB port. Raspberry PI will process the image data obtained webcam camera input. Next, If the ball object can be detected the object's position coordinates will be encoded in character and sent to the Microcontroller Arduino Mega 2560. Furthermore, Arduino mega 2560 will process data to drive the motors so that can move towards the position of the ball object. Based on the data from the maximum distance test results that can be read by the camera sensor to be able to detect a ball object is �5 meters with a maximum viewing angle of 120 �.

Raspberry Pi is a credit card-sized SBC (Single Board Computer) developed by the Raspberry Pi Foundation in the UK with the aim of teaching basic computer science at school. Raspberry Pi can be used for various things including wireless. In this study will be carried out the implementation of wireless routers by using Raspberry Pi as the main media. This is done to implement the use of Raspberry Pi devices as an alternative to Wireless Routers or in the world of networking. The Wireless Router implementation method used is the PPDIOO network cycle method owned by CISCO which has the stages of Prepare, Plan, Design, Implement, Operate, and Optimize. Wireless Router implementation uses several devices between Edimax - Wireless 802.11b / g / n usb wireless adapter as a device or Broadcast Wireless Raspberry Pi media as the main function of the device and system owned by the Wireless Router. Wireless Routers using Raspberry Pi become one of the best solutions for the needs of adding new wireless network segments if you see in terms of limited funds and existing devices. An administrator will easily build a new network using Raspberry Pi.

In this paper, an integrated system to control and manage a state-of-the-art industrial computer numerical control (CNC) machine (Studer S33) using a commercially available tablet (Samsung Galaxy Tablet S2) is presented as a proof of concept (PoC) for the ubiquitous control of industrial machines. As a PoC, the proposed system provides useful insights to support the further development of full-fledged systems for Industrial Internet of Things (IIoT) applications. The proposed system allows for the quasi-decentralisation of the control architecture of conventional programmable logic controller (PLC)-based industrial control systems (ICSs) through data and information exchange over the transmission control protocol and the internet protocol (TCP/IP) suite using multiple agents. Based on the TCP/IP suite, a network device (Samsung Galaxy Tablet S2) and a process field net (PROFINET) device (Siemens Simatic S7-1200) are interfaced using a single-board computer (Raspberry Pi 4). An override system mainly comprising emergency stop and acknowledge buttons is also configured using the single-board computer. The input signals from the override system are transmitted to the PROFINET device (i.e., the industrial control unit (ICU)) over TCP/IP. A fully functional working prototype is realised as a PoC for an integrated system designated for the wireless and ubiquitous control of the CNC machine. The working prototype as an entity mainly comprises a mobile (handheld) touch-sensitive human-machine interface (HMI), a shielded single-board computer, and an override system, all fitted into a compact case with physical dimensions of 300 mm by 180 mm by 175 mm. To avert potential cyber attacks or threats to a reasonable extent and to guarantee the security of the PoC, a multi-factor authentication (MFA) including an administrative password and an IP address is implemented to control the access to the web-based ubiquitous HMI proffered by the PoC.
