Light-emitting diode (LED) lamps become popular in a variety of applications, due to low power usage, high efficiency, and low maintenance. Another advantage of LEDs is that they are durable and environmentally friendly because they contain less toxic substance composition compared to other types of lamps. To achieve high efficiency in energy transfer to the LED power supply, a switching mode power supply (SMPS) is applied. SMPS was implemented with pulse width modulation (PWM) which operates at a constant frequency, producing significant emissions in several frequencies through conducted and radiated mechanisms. These emissions are called electromagnetic interference (EMI). As a result, many LED lamps have the potential to fail to meet the electromagnetic compatibility (EMC) standard. In this research, the design and implementation of passive EMI filters were carried out to reduce the conducted emission of LED lights on the market. Passive EMI filters are LC low pass filters (LPF). Before the LED lights were applied to the EMI passive filter, conducted emissions were measured to exceed CISPR 22 class B regulatory standards, which reached 82.5 dBµV. When the passive EMI filter was implemented, the LED lights occur conducted emission reduction in the frequency range 150kHz - 1.5MHz with an average value of 36.96 dBµV and a maximum reduction value of 34.7 dBµV.

In this research, a prototype of Arduino-based robot arm manipulator (MLR) controlled with lead-through method is proposed. Through lead-through control methods, the robot movement programming process is replaced by a simple and easy robot movement recording process. The recording process is performed when parts of the MLR are manually moved by the user. Afterwards, the playback process of the recorded movement can be performed. The MLR has 4 degrees of freedom and uses four servo motors to perform rotational movement, upward-downward movement, forward-backward movement, and gripping movement. The servo motors are modified so that each of them has one additional terminal that serves to provide position feedback. On the recording process, the position of all servo motors is recorded on Arduino Uno EEPROM every 200 milliseconds time interval. In the playback process, the recorded position is sent to the servo motors as input, and the MLR repeats the recorded movement. The MLR is tested to move workpieces with accuracy requirement of ± 3cm. MLR is able to repeat the movement to move 1 workpiece for 30 cm displacement with a success rate of 80%. In addition, MLR is able to playback the movement to move 2 workpieces for 60 cm displacement with a success rate of 85%.

Bandwidth limitations and fluctuations in traffic on the network become obstacles in the process of sending video. At the time of the availability of small bandwidth and high network traffic, the process of sending video will take a long time due to the operation of slow video transmission or more commonly called buffering. This study evaluates sending live streaming video using the Dynamic Adaptive Streaming over HTTP (DASH) method on the LAN network. DASH is an adaptive streaming protocol that can present the video with video quality according to network capabilities on the client. This implementation is carried out using H.265 video compression and the streaming process is carried out on a LAN network with 20 live streaming clients. The results of this study obtained the value of video delivery throughput reaches 1.4 Mbps and the most significant delay value is 12.5 ms. The highest percentage of client requests for video quality for one client is 98%. As for the use of 20 clients, the demand for high-quality video is reduced to 46% which proves that DASH was successfully implemented live streaming. Keywords: Video, Live, Streaming, H.265, DASH

Coffee is a beverage that is relatively favored by the people of Indonesia because of its taste and aroma. Takengon, Central Aceh district is one of the regions producing coffee beans in Indonesia. Many of the coffees we drink today are the result of coffee plantations originating from there. But many do not know that the process of making coffee drinks is not so easy, especially during the process of stripping the skin on coffee beans. The process of stripping the coffee husk is carried out by the community usually by turning the mill manually which is rotated by hand. Thus came the idea to make a Coffee Skin Peeling Machine Using Two Knives that can simplify the process of stripping the coffee skin efficiently and simply. This machine has 2 parts that can facilitate the stripping process, namely the rectifier shaft and paring knife. This machine can separate the results of stripping between beans and coffee mechanically and the best stripping percentage during the stripping process is 83% with an error percentage of 17 %.
