Penelitian ini dilatarbelakangi oleh kejenuhan siswa dalam sistem pembelajaran konvensional yang hanya tatap muka dengan didominasi metode ceramah antara guru dengan siswa. Di sisi lain fasilitas perangkat komputer dan koneksi internet di SMKN 2 Kota Bandung sudah sangat memadai untuk penerapan pembelajaran berbasis online. Tujuan penelitian ini untuk mengetahui apakah penerapan Social Learning Network berbasis Schoology yang diterapkan pada kelas eksperimen dapat meningkatkan hasil belajar siswa. Metode penelitian yang digunakan dalam penelitian ini adalah metode pre-experimental, dengan desain one-group pretest-posttest. Instrumen yang digunakan adalah instrumen tes hasil belajar untuk aspek kognitif, lembar penilaian afektif, lembar penilaian psikomotor, dan angket evaluasi pembelajaran bagi guru dan siswa. Hasil penelitian menyebutkan bahwa tahapan penerapan Social Learning Network berbasis Schoology melalui dua tahap utama, yaitu studi pendahuluan dan pengembangan media. Penerapan Social Learning Network berbasis Schoology berpengaruh signifikan terhadap peningkatan hasil belajar dalam ranah kognitif, afektif, dan psikomotorik.

Fuzzy-PID in BLDC Motor Speed Control Using MATLAB/Simulink

Brushless DC motors (BLDC) are one of the most widely used types of DC motors, both in the industrial and automotive fields. BLDC motor was chosen because it has many advantages over other types of electric motors. However, in its application in the market, most of the control systems used in BLDC motors still use conventional controls. This conventional method is easy and simple to apply but has many weaknesses, one example is that if the system state changes, then the parameters of the PID must also be changed so that static and dynamic performance will decrease, causing slow response and frequent oscillations. In this study, the design and simulation of a speed control system for BLDC motors using the Fuzzy-PID method were carried out. The research method is performed through simulation with Matlab / Simulink. The simulation is carried out by providing a speed setpoint input of 650 rpm and used 2 methods, namely Fuzzy-PID Logic and Pi conventional method which was carried out for 1 second. The test results show that the Fuzzy-PID control can provide better and more stable performance than the conventional PI control. The use of Fuzzy-PID control can reduce speed fluctuation and torque stability so that the BLDC motor can operate more efficiently and reliably

Hybrid fuzzy-PID like optimal control to reduce energy consumption

The electric motor is one of the appliances that consume considerable energy. Therefore, the control method which can reduce energy consumption with better performance is needed. The purpose of this research is to minimize the energy consumption of the DC motor with maintaining the performance using Hybrid Fuzzy-PID. The input of the Fuzzy system is the error and power of the system. Where error is correlated with matric Q and power is correlated with matric R. Therefore, adjusting the fuzzy rule on error and power is like adjust matrices Q and R in LQR method. The proposed algorithm can reduce energy consumption. However, system response is slightly decrease shown from ISE (Integral Square Error). The energy reduction average is up to 5.58% while the average of ISE increment is up to 1.89%. The more speed variation in the system, the more energy can be saved by the proposed algorithm. While in terms of settling time, the proposed algorithm has the longest time due to higher computation time in the fuzzy system. This performance can be increased by tuning fuzzy rules. This algorithm offers a solution for a complex system which difficult to be modeled

Embedded Position Control of Permanent Magnet Synchronous Motor Using Model Predictive Control

This paper presents an implementation embedded system for position control of Permanent Magnet Synchronous Motor (PMSM). The control system consists of raspberry pi 3 as a microcontroller, ASDA-A2 servo drive, and Delta Servo ECMA type. The software design includes simulation tool and Python included on Raspbian OS. Communication between Raspberry Pi 3 and ASDA-A2 drivers using the ASCII Modbus communication protocol. Raspberry Pi 3 processes the reference data and the actual reading result and calculates the resulting error. The control algorithm used in this research is Model Predictive Control (MPC). As a Linear Quadratic Regulator, MPC aims to design and generate an optimal control signal with the ability to anticipate saturation, receding horizon, future event and take control accordingly In the design of the MPC technique to adjust the speed of the PMSM to take action of reference tracking, performance index optimization is done by adjusting the value of weighting horizon N, Q and R. The simulation and implementation results showed that the PMSM can reach the stability point on each desired setpoint and result in a near-zero steady-state error

Design and implementation of an automatic control for a laptop battery charger

In the process of charging laptop's battery, there is no automatic settings are disconnected and connecting the laptop charger voltage according to the needs and desires of the user. In addition, the apathetic nature of the laptop users often also lead to battery charging voltage overload on the laptop battery. These conditions will have an impact on the voltage of the battery leakage which will eventually be more easily damaged. In addition, the electrical energy will continue to flow from adaptor to the laptop and the resulting dissipation of electrical energy within a certain period. From some of these problems, the authors had the idea to make the tool as a form of solution that charging automatic controller. The tool is designed to regulate battery-charging time through additional software on the laptop. The method used was an experimental method. Results of this research have shown that these tools not only cut off the voltage from the adapter to the laptop, but also classes decide the flow voltage of 220V AC power adapter to the charger. Therefore, this tool provides two benefits at once, ie maintain the lifetime of the battery and also save electrical energy use
