<![CDATA[This study aims to analyze the Study of Effect of the Role of Parents and the School Environment on the Learning Outcomes of Class X Students in Basic Electrical and Electronics Subjects During the Covid-19 Pandemic At SMKN 1 Koto XI Tarusan. The type of research that the author does is a type of quantitative research with a causal associative approach. Data collection was carried out using research instruments by providing a questionnaire with a Likert scale. In variable X1 it was found that a total of all nine indicators of the X1 variable with the respondent's level of achievement of 90.8% and it was stated that the role of parents was good, on the X2 variable it was found that all of the six indicators of the role of the school environment resulted in an accumulation of an average score of 2.87 with the respondent's level of achievement ( TCR) of 114.69%, it can be concluded that the role of the school environment is said to be good and can still be improved. Hypothesis testing was carried out by using multiple linear regression tests T-test (t-test) and F-test. T-test was conducted to partially test the effect of the independent variable on the dependent variable. The F test was conducted to test the effect of the independent variable simultaneously on the dependent variable. The results showed that: (1) there is no influence of parents on student learning outcomes; (2) there is no influence of the school environment on student learning outcomes; (3) there is no influence of the role of parents and the school environment simultaneously on the role of parents in Basic Electrical Electronics subject for class X SMKN 1 Koto XI Tarusan.]]>

<![CDATA[Direct current (dc) voltage sources are one of the voltage sources most widely used for various purposes. Dc voltage can be obtained from a dc generator or by converting an ac voltage into a dc voltage using a power converter. There are several dc voltage levels that are commonly used by electrical and electronic equipment. To get a dc voltage that can be used for various equipment, then a dc voltage source must be varied according to the required. One way to get a variable dc voltage is to use a dc-dc converter. This research proposes a dc-dc boost converter that can increase the dc voltage with varying outputs. The boost converter is proposed using Arduino Uno as a controller with an input voltage of 12 volts. The converter output voltage regulation is implemented through Arduino programming using Matlab simulink. The experimental results show that the boost converter designed in this study has worked well as intended. This can be seen from the boost converter output voltage which is in accordance with the reference voltage entered in the Matlab simulink program]]>

<![CDATA[Solar power plant (PLTS) is a renewable energy power plant that is starting to develop in Indonesia as fossil energy is decreasing as the main energy source for electricity generation. This PLTS works by converting sunlight energy into electrical energy using solar panels. Increasing the efficiency of PLTS can be done by controlling the solar panels at their maximum power point. The maximum power point of the solar panels can be obtained by finding the maximum solar radiation or by controlling the output voltage of the solar panels at the maximum power point using a power converter. This research proposed a maximum power point of solar panels by regulate the output voltage using boost converter, which is also called the maximum power point tracking (MPPT). MPPT control system is proposed using an incremental conductance algorithm which is implemented using Arduino Mega 2560 programmed with Matlab simulink. MPPT control system is designed for four 50 WP solar panels connected in parallel. The experimental results show that the proposed MPPT control system with the incremental conductance algorithm is able to control the output power of the solar panels at the maximum point]]>

<![CDATA[Wind power is a type of renewable energy power plant that is starting to develop in Indonesia. This plant uses wind turbines to convert wind power into mechanical power that will drive the generator. The generators used in this wind power plant have limited capabilities. In order to prevent operation that exceeds the capacity of the generator, it is necessary to monitor and protect the components of the wind power generator. This study proposes a wind power generator monitoring system using the Arduino MKR 1000 based on the Matlab Graphical User Interface (GUI). Wind power plant parameters that are monitored are wind speed, turbine rotation speed and generator output power. The tool made was tested on a wind power plant in the laboratory that uses a horizontal axis wind turbine with a permanent magnet type generator. The test results show that the wind power generator monitoring system made in this study has worked well. This can be seen from the wind speed data, the turbine rotation speed and the generator output power data displayed on the monitoring screen in accordance with the data available on the measuring instrument.]]>

<![CDATA[Energy listrik merupakan sumber energi yang banyak digunakan dalam kehidupan sehari hari salah satunya aki. aki merupakan tempat penyimpanan sumber listirik yang praktis yang mudah dibawa dan digunakan sesuai kebutuhan sehari hari. Sedangkan jika aki dipakai terus menerus maka tegangan aki akan menjadi kosong , oleh sebab itu diperlukan pengisian ulang terhadap aki, agar aki dapat terisi dengan baik diperlukan pemantauan pada saat pengisian agar didapatkan hasil yang maksimal. Pada pemantataun pengisian aki ini meliputi, tegangan aki, suhu aki , tegangan panel surya sekaligus sebagai penyuplai tegangan untuk pengisian aki , dan mengunakan relai sebagai pemutus tegangan ketika Tegangan aki sudah terisi penuh supaya tidak terjadi kerusakan terhadap aki akibat kelebihan Tegangan yang masuk pada saat pengisian aki. Komponen yang dibutuhkan adalah sensor tegangan, sensor db18b20, relai . Semua komponen pada alat ini dikendalikan oleh Arduino yang dikoneksikan melalui Simulink untuk selanjutnya dikirim ke Gui Matlab sebagai tempat hasil pengujian berupa angka dan grafik.]]>

<![CDATA[Based on the source used, there are several types of converters, one of which is a voltage source converter (VSC). In this study, using a converter that can work as an inverter. In industry, an inverter is useful for supplying the AC voltage source from industrial plants with DC sources, by varying the voltage and output frequency of the inverter. The method used is the HCCPWM generation method or Hysterisis Current Control Pulse Witdh Modulation. This method was chosen because it has several advantages which are good stability, very fast transient response and good accuracy. To activate HCCPWM, a 3 phase reference current signal is first made in the Matlab Simulink, this reference current is then compared with the actual current from the current sensor, then the error is controlled with the hysteresis band. In Arduino mega2560, the pulses generated by HCCPWM in the Matlab Simulink are converted into a duty cycle. The modulated pulse generated by the Arduino PWM pin will be increased using a gate drive circuit, so that the voltage is obtained according to the voltage required by the Mosfet to activate the switch. The results of the tests that have been done show that the voltage source converter (VSC) designed in this study has worked well as intended. This can be seen from the actual current from the current sensor which has been compared with the reference voltage using the HCCPWM method which is included in the Simulink Matlab program.]]>

<![CDATA[Solar panels are a renewable energy power plant that uses sunlight as its main energy source. The power generated by solar panels are determined by the size of the solar panels, solar radiation and temperature. The power of the solar panels is also determined by the output voltage of the solar panels. To get the maximum output power at any time, it is necessary to adjust the output voltage of the solar panel. This study proposes controlling the maximum output power of solar panels, also known as maximum power point tracking (MPPT) by adjusting the output voltage of the solar panels using a buck converter. The buck converter output voltage regulation at the maximum power point of the solar panel is designed with the Perturbation and Observation (PO) algorithm which is implemented using an Arduino Mega 2560. This MPPT control system is applied to 4x50 Watt-Peak (WP) solar panels which are connected in parallel. The experimental results show that the proposed MPPT control system with the PO algorithm has worked well as expected. This can be seen from the output power generated by the solar panels already around the maximum power point at any change in solar radiation and temperature.]]>
