<![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]]>

<![CDATA[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.]]>

<![CDATA[The High Order Average (ROT) value in the data is an extension of the First Order Mean. There are two methods to find the High Order Average, namely the first step by step and the second directly. The ROT method can directly use the IN Series. Because the process of adding data in stages does not need to be done one by one, the direct ROT method is more effective and efficient. In this study, the two methods will be compared to each other with the results of calculating the ROT data from polynomial functions. ROT calculation results from both methods have the same value. Keywords: Average, IN Series, Interpolation, ROT]]>

<![CDATA[Technological developments are getting faster, as is the dissemination of existing information, especially on the capital market. In order for investors to avoid losses from the capital market, a method is needed that is able to analyze the movement of the stock price. This study focuses on the application of the Data Scales Analysis (DSA) method which uses a formula with the concept of the same amount of data between the first and second order average differences at levels n and n + 1 for predicting the stock price of issuers, in predicting stock prices in the capital market. The resulting formula is named JIC-FLY 2 which is a new formula used to predict stock prices in the capital market. The population used in this study are issuers who are members of IDX 30 from the banking sub-sector with the sample used is the issuer of BBCA (PT Bank Central Asia Tbk). The results of this study note that the DSA method with this formula is able to produce the best predictive value, namely DSA 12 with an error percentage of 0.035%.]]>

<![CDATA[The existence of cogging torque in electric equipment has been considered undesirable. This kind of friction in the air-gap impacts the alignment of flux and the stator slots, resulting in the observed outcome. Consequently, the imposition of restrictions on the rotation of the rotor is employed to generate electrical energy. This research endeavor primarily aims to mitigate the cogging torque of electrical machinery. The current utilization involves employing a total of 3 permanent magnet synchronous machines, often known as inset PMMs, which possess a slot count of 24 and a pole count of 8. The employed technique involves the integration of an optimal pole arc method in conjunction with the implementation of slots cut into the magnet's edge. The machine model under investigation has two fundamental variants, namely Models 1 and 2. These models are equipped with 1one-step slotted (OSS) and 2two-step slotted (TSS) edges on each magnet, in addition to pole arc optimization. The simulation was conducted using the Finite Element Method Magnetics (FEMM) 4.2 software together with LUA scripts, with a focus on rotor rotation ranges of 1 degree. Model 2 exhibited a decrease in cogging torque of 0.01 Nm, whereas Model 1 demonstrated a reduction of 0.015 Nm, and the basic model had a decrease of 0.02 Nm. When implementing a dual-layered cutting edge on a magnet and attempting to optimize its pole arc, it is imperative to consider that the cogging torque's peak magnitude becomes substantially diminished or entirely eliminated.]]>
