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

Persaingan di bidang industri telah mendorong untuk dilakukannya proses otomasi dalam mengoperasikan peralatan mesin-mesin industri dan kontrol proses untuk menggantikan operator tenaga manusia. 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.

The process of heating in the food industry is often can be found, start from inserting water and the heating process begin to reach a certain temperature, so the process of controlling temperature is one of the important things in the food industry. Temperature controller is an important thing, to maintain certain temperature, so that it did not exceed or lower than needed. This system uses Honeywell programmable logic controller (PLC) as the automation based system. In this research, Honeywell PLC controller will be using proportional, integral, derivative (PID) algorithm to maintain the required temperature. The research will be using the Honeywell module in Automation Laboratorium, Engineering Faculty, Atma Jaya Catholic University of Indonesia. The heating process will begin if the water level in the tank is filled to the required level. System will turn on the heater based on the PID output in the PLC program, so the temperature is maintained to a required setpoint 35oC. The simulation system can be controlled through a human machine interface (HMI) HCix08 that was made with XDesigner Plus software. The maintained temperature has ±5% tolerance or ±1,75˚C. The result of the research shows that the best parameter for setpoint 35˚C is using a PD controller with the values for Kp is 8 and Kd is 2.
