Proteksi transformator berfungsi untuk memproteksi transformator apabila terjadi gangguan, sehingga transformator dapat terhindar dari kerusakan. Dalam paper ini akan dibahas tentang relay differensial yang digunakan untuk memproteksi transformator. Relay ini bekerja apabila terdapat perbedaan arus pada CT sisi primer dan sekunder di zona proteksi. Apabila gangguan terjadi di luar zona proteksi, relay tidak akan bekerja. Penelitian ini berupa simulasi dengan menggunakan perangkat lunak PSCAD/EMTDC versi 4.2. Data-data yang digunakan adalah data dari sistem WSCC 3 Machine 9 Bus Systems. Dalam simulasi ini akan dilihat unjuk kerja dan selektifitas relay differensial, nilai arus pada PMT, serta waktu trip relay differensial di zona proteksi (internal) maupun di luar zona proteksi (eksternal). Dari hasil simulasi menunjukkan bahwa pada saat terjadi gangguan internal, relay trip (pick-up) selama 0,15 detik, yaitu dari 0,22 detik sampai dengan 0,37 detik, sedangkan pada gangguan eksternal relay tidak trip (pick-up).

The warehousing system is a means of supporting production activities and industrial operations that function to store goods to be distributed, which are still using a manual system and must adapt to technological developments. The problem that often arises in the warehousing system that is still done manually is that the flow of goods into the warehouse is not well organized, and this makes it difficult when the goods are about to be removed, so it requires a longer search time. Previous research has shown actual data on storage racks that use Arduino Mega as a controller and VB as an interface, but there is no actual data on the state of the lifter or the selection of lifter movement speed modes to facilitate operators in monitoring and operating goods storage. Control systems with industry standards greatly affect the effectiveness and optimization of the production process. Based on these problems, this research aims to simplify the managerial and monitoring process in the warehouse with a prototype of automatic multilevel storage using PLC CP1H and CP1L as system control and Wonderware Intouch as an interface with the SCADA system. The prototype has 12 cells, and each cell can accommodate 2 boxes; each cell is distinguished by the height and color of the box. In testing this research, the SCADA system can work optimally. The interface is capable of displaying the actual data of the rack with a success rate of 100%, the hardware error rate is less than 1%, and the interface can display the actual data on the state of the lifter.

Process of identifying fetal heart sound signals is imperative in recognizing congenital heart function that caused by many factors, such as hereditary factors and food intake of pregnant mothers. This study developed a method for processing heart signals to separate normal fetal phonocardiogram signals from noise by utilizing the Complete Empirical Mode Decomposition (CEEMD) algorithm which is integrated with the Pearson Distance metric. Heart signals that have been separated from noise are then processed using the Shannon Energy equation in order to sharpen the intensity of the first heart signal (S1) and the second heart signal (S2), but at the same time suppress the intensity of the residual noise in the signal. Based on the experiment results from 75 normal fetal heart sound cycles, the model that has been developed is able to identify the S1 signal and S2 signal, the time duration of T11 (S1-S1), and the time duration of T12 (S1-S2). Average duration of T11 and T12 acquired in this research can possibly be used as a reference for measuring the normal duration of fetal heart sound signals.

Measurement process of concrete mold erectness (bekesting) and the floor slope was generally conducted using conventional method applying a plummet (pendulum) for bekesting erectness and waterpass for the floor slope. The drawbacks of this method are it requires a relatively longer processing time and the outcome of the slope measurement is not represented in degrees. The measurement of digital plummet and digital waterpass is easier as the measurement time is relatively short and the tilt angle is represented in degrees. This paper describes a design and implementation of digital plummet and waterpass using Accelero Sensor MMA 7361L based on microcontroller ATmega8. The Accelero sensor MMA 7361L was used to read the tilt axis x, y, and z with analog voltage output that is converted into digital form using the ADC on the microcontroller. Based on the results of tools test for bekesting erectness and floor slope measurement, it was obtained that the average error were 0.51% and 0.49% for x-axis and y-axis respectively.

Rapid technological development, triggering various applications development that are increasingly innovative. One of them is the Internet of Things (IoT) system that makes human works easier and more effective. Along with sensor technology development in monitoring and controlling through IoT systems, a mechanism is needed to manage bandwidth so that IoT system can function optimally, especially in buildings designated as public areas. Smart building supported by various integrated sensors to maintain safety and comfort in the area. This study proposes the application of Elastic WLAN as a model for dynamic bandwidth management in IoT systems. In this model, IoT bandwidth changes automatically according to the number of traffic measurements for each IoT connected to the network As an effort to determine the performance of the elastic WLAN mechanism, this study succeeded in developing a prototype IoT device that implements Elastic WLAN on an Access-Point Raspberry Pi by using two temperature sensors placed in separate locations. The system successfully allocates bandwidth to each IoT according to the amount of data input from each temperature sensor installed. The higher the amount of data captured by the sensor, the system will automatically allocate the higher bandwidth to the sensor system, and vice versa.

Solar modules have current and voltage characteristics that are non-linear, so efforts must always be made to work at the maximum power point so that no energy is wasted. The characteristics of the solar module will change depending on the level of radiation and temperature which causes the output power of the solar module to fluctuate and become unstable. To reduce oscillations in the output power of the solar module, the Fuzzy Logic Control (FLC) method used using the boost converter. Several studies have been done to maximize the output power of solar panels, one of which is by using namely by using Maximum Power Point Tracking (MPPT). This study aims to obtain the maximum power point in a set of solar modules arranged in series and parallel through the performance of the FLC method. In tracking the maximum power point during normal operation, the fuzzy method works together with a boost converter. Fuzzy-based MPPT was tested on a solar module under several radiation and temperature conditions using Matlab / Simulink software. The Fuzzy design method shows better results compared to other methods. The results obtained show the advantages of the FLC method in terms settling time, power loss, and oscillation at the point of the operating system.

Standard headlights will shine with a fixed intensity even though the environmental light changes. High-intensity lights sometimes make other drivers glare and potentially cause accidents. Adaptive Light Control (ALC) is a car headlights control system that can automatically adjust the intensity of the lamp according to the intensity of the light environment. In this research, we developed ALC which was able to regulate the intensity of the lamp according to the intensity of the environmental light including the light of the car in front. Light settings are performed using a fuzzy control system by utilising environmental light intensity and the distance of the car to the object as input. The developed ALC system was tested on remote control cars equipped with sensors and microcontrollers. The intensity of headlight begins to fade on the distance of the car to the object of 92 cm for objects in front of, 108 cm for objects on the left, and 22 cm for objects on the right.
