<![CDATA[This paper will discuss the calculation of inverse kinematic which will be used to control the 6-DOF articulated robot. This robot consists of 6 Dynamixel MX-28 smart servo with OpenCM 9.04 microcontroller. The articulated robot has been simplified to 4-DOF because there are no obstacles in the work area and no special movements are required. The calculation method uses the intersection point equation between the ball and the line, so that it can make it easier to determine the point in calculating the kinematic inverse. The experiment is carried out using the desired position as input for the kinematic inverse to produce the angle of each joint. From the angle of each joint obtained, it will be entered into forward kinematic so that the end-effector position will be obtained. The desired position will be compared with the end-effector position, and then how much difference will be calculated. From the experimental results, it was found that the inverse kinematic method which has been inverted by the forward kinematic produces the same final position. Keywords: 6-DOF manipulator, Articulated robot, inverse kinematics and forward kinematics, Dynamixel MX-28, OpenCM 9]]>

<![CDATA[This study aims to analyze robotics simulation tools that can be used to support algorithm development in the robot modelling process. There are several simulation tools for robot algorithm modelling that are popularly used by robotics developers. This study focuses on analyzing the effectiveness based on the features of the Robot Operating System Development Studio (ROSDS) and MATLAB as a development simulation platform using the comparative method. The results of this study claim that ROSDS is more effective than MATLAB in terms supporting the development of robotics simulation because ROS is used as a middleware in ROSDS that connects the communication between the program with the robot, so that makes it easier for making robotics simulation and ROSDS is easier to access than MATLAB. The trial case study of developing trajectory algorithm in the robot arm was carried out in this research to support the statement above, and it worked out well.]]>

<![CDATA[This paper is about to discuss the effect of combining a magnetic shaping technique with an axial channel in the rotor core to reduce the cogging torque of a permanent magnet synchronous generator. Computation process is performed by using the optimization response surface method. In this case, this research is done by employing two types of axial channel systems, namely circular and hexagonal. The axial channel area at the core of the engine rotor is 0.000279683 m2. Determination of magnetic shaping was carried out with an angle of 10 and a surface angle of 530. The effect of the combination of the cogging torque reduction technique with magnetic shaping and axal channel was analyzed by numerical method based on the finite element method (FEMM). Based on the analysis, it is found that the combination shows a decrease in cogging torque by 98% when compared with the cogging torque in the initial design (initial structure). Another advantage of the combination of the two cogging torque reduction techniques is that there is no significant increase in the magnetic flux density of the engine core. It can be said that the combination of the cogging torque reduction technique and the axial channel at the core of the engine rotor can significantly reduce the cogging torque.]]>

<![CDATA[Currently, technology in the telecommunications sector is developing rapidly.Telecommunication users need fast communication technology with wider bandwidth. Therefore, FBMC / OQAM was developed, which is a modulation candidate technology to be used in 5G. FBMC / OQAM is a development of OFDM which is modified by using filters to reduce noise. OFDM uses a multiplexing technique that divides bandwidth into several sub-carrier frequencies. But OFDM has a weakness, because it requires a Cyclic Prefix (CP) to overcome Intersymbol nterference (ISI) and Intercarrier Interference (ICI). With FMBC, the increased bandwidth due to the Cyclic prefix can be reduced. The filter used is based on the Physical layer for dynamic spectrum access and cognitive radio (PHYDYAS).The results achievedin this study were that FMBC was succesfully and the data sent was the same as the data received]]>

Teknologi robot merupakan bagian dari otomasi yang banyak diterapkan di industri, salah satunya adalah lengan robot. Pada proses produksi, lengan robot digunakan untuk memindahkan objek. Dibutuhkan perancangan yang benar agar lengan robot dapat bergerak sesuai dengan kriteria yang diinginkan. Oleh karena itu pada penelitian ini dilakukan perancangan dan pembuatan purwarupa lengan robot yang memiliki lima derajat kebebasan atau Degree of Freedom (DoF) dan dilengkapi dengan pencapit objek. Sebagai pengendali lengan robot digunakan mikrokomputer Raspberry Pi 3 Model B+ yang diprogram dengan perangkat lunak python. Pada lengan robot terdapat kamera untuk mendeteksi warna objek agar lengan robot dapat memindahkan dan menempatkan objek sesuai kelompok warnanya. Pengujian terhadap rancangan lengan robot menunjukkan bahwa kamera dapat mengenali warna objek dan lengan dapat memindahkan objek sesuai pada tempatnya. Competition in the industrial sector has pushed for automation processes in operating industrial machine tools and process control to replace human labor operators. Robot technology is a part of automation that is widely applied in industry, one of which is the robot arm. In the production process, robotic arms are used to move goods. Correct design is needed so that the robot arm can move according to the desired criteria. Therefore, in this study, the design and manufacture of a robot arm prototype that has five degrees of freedom (DoF) is carried out and is equipped with a clamp. As a controller for the robot arm, a Raspberry Pi 3 Model B + microcomputer is used, which is programmed with python software. On the robot arm, there is a camera to detect the color of the object so that the robot arm can move and place object according to the color group. Testing of the robot arm design shows that the camera can recognize the color of goods and the robot arm can move object according to their place.]]>

<![CDATA[Pemantauan kesehatan pasien jarak jauh untuk menjelaskan kondisi kesehatan pasien telah mendorong manusia untuk membuat sistem pemantauan kesehatan berbasis IoT (Internet Of Things). Pemantauan dirasa penting untuk pasien yang berbaring di kasur dan tidak bergerak dalam jangka waktu yang lama, karena kondisi tersebut dapat menimbulkan ulkus dekubitus. Untuk mencegah masalah tersebut digunakan matras pereduksi dekubitus yang mengubah titik tumpu pada kulit secara berkala. Ada kondisi saat matras mengalami malafungsi, dan matras tidak lagi mengubah titik tumpu pada kulit secara berkala. Untuk itu perlu adanya pemantauan tekanan kantung udara matras sehingga kondisi tersebut bisa diatasi. Raspberry Pi 3 menjalankan simulasi perubahan siklus tekanan kantung udara pada matras secara periodik. Data simulasi tersebut akan dikirimkan ke server menggunakan modul GPS/GPRS SIM868 dan akan disimpan dalam database. Lokasi alat dapat diketahui dengan menggunakan modul GPS yang terintegrasi dalam modul GPS/GPRS SIM868. Dalam halaman web ditampilkan simulasi kembang kempis kantung udara matras yang diindikasikan dengan warna. Modul GPS/GPRS SIM868 dapat berkomunikasi dengan Raspberry Pi dan dapat mengirimkan data simulasi perubahan siklus tekanan udara pada matras. Pengujian tampilan halaman web dengan siklus simulasi kembang kempis kantung udara dengan indikasi perubahan warna pada matras sudah sesuai dengan data simulasi tekanan kantung udara yang dikirimkan dari Raspberry Pi ke database.]]>

<![CDATA[In today’s industry, company’s activities are scattered in several locations and need internet for communication purposes. However, it will be dangerous if third-parties have access to their information. One of the solutions for securing information exchange is by using Virtual Private Network (VPN). The VPN protocols that will be used are Point-to-Point Tunneling Protocol (PPTP) with the help of Internet Protocol Security (IPSec). These protocols are simulated in VirtualBox that has been previously installed with two Mikrotik routers and two Windows 7 operating systems. The PPTP and IPSec protocols are configured in both routers through Winbox software. For the computers, the IP addresses are configured along with iPerf software for bandwidth analysis. In this VPN simulation, both computers can communicate with each other and have no problem in accessing the internet. In PPTP’s network, the average bandwidth is 1.293 Mbits/sec. Meanwhile, in PPTP with IPSec’s network, the average bandwidth is 0.853 Mbits/sec. There is a slight difference considering that in PPTP, the data packets are only encapsulated. On the other hand, the data packets in IPSec protocol are both encapsulated and encrypted.]]>
