At the Banyupoh Feeder there is a Gondol Hubung Substation, which has 2 outgoings, the first line goes to the Banyuwedang Feeder and the second line goes to Penyabangan. However, because there is no protection on the outgoing side, if there is a disturbance in the first section on one of the outgoing sides, it will cause 1 feeder with a total of 49 transformers to experience a blackout. To overcome this condition, it is necessary to add relays at the substation. After the addition of relays at the substation, the impedance and short-circuit current are recalculated which can be used to determine the timing of the OCR and GFR relays at the new substation for each outgoing. The calculation results are then converted into a curve to determine the coordination of the protection with the existing protection relays on incoming, outgoing and recloser in anticipating disturbances in the first section at the Banyupoh Feeding Substation. After setting the protection relay on the outgoing side of the substation, the outage area due to interference can be minimized. When section 1 of the Banyuwedang Feeder is disturbed, the relay on the outgoing Gondol Substation will work so that the Energy Not Served (ENS) which was previously 40.008 kWh becomes 20.511 kWh. If section 1 of the Feeding Feeder is disturbed, then the relay on the outgoing Substation Hubung Gondol will work so that the ENS which was previously 40.008 kWh becomes 19,497 kWh, so that the amount of energy that is not channeled is reduced by 50% and this makes the service better.

In this new era the use of Photovoltaic (PV) is increasingly being used as an energy source. However, this technology has a drawback, namely, the intensity of the sun's light is always changing every time. This can cause the output voltage of the Photovoltaic (PV) Cell to be variable or indeterminate. In the Photovoltaic (PV) Cell, a dc-dc converter circuit is needed which functions to regulate and change the output of the Photovoltaic (PV) Cell. Conventional DC-DC boost converters are unable to provide a high step-up voltage boost due to the effects of switching power, rectifier diodes, and equivalent series resistance of inductors and capacitors. In this study, a closed loop design using a PID controller and analysis of a non-isolated boost dc-dc converter based voltage lift technique were carried out to achieve a high step-up voltage gain. In the presented converter two inductors, three capacitors and three power diodes are used. From this structure, this converter is referred to as a voltage lift cell-based boost converter. The structure of the presented converter is considered very simple, since it has only two stages of power. The voltage and current equations of each element with the converter voltage gain under continuous conduction mode (CCM) were extracted. In addition, the steady state analysis of the amplified stress and boundary conditions is discussed in this study. This boost converter circuit is simulated through the PSIM application. From the simulation results in the PSIM application, it is found that the boost converter circuit is able to increase the voltage from 100 V to 400 V and has an error value of 0. The specifications of the simulation results are a duty cycle of 0.6, and a frequency of 10,000 Hz.

One type of power converter that is widely applied in the field of renewable energy is DC-DC Converter. In variousapplication cases, voltage control features are often required. One of the challenges is how to build a closed loop controller to control the output voltage of the DC-DC Converter. In this journal, an Arduino Mega based output voltage controller will be implemented. The type of voltage controller implemented is the PI controller with the consideration that the controller has been well-known tested and mathematically proven. The PI controller is set based on closed loop block diagram calculations with the Buck Converter as the main plant. The implementation of the PI controller on the Arduino Mega is based on the expected transient response settings. PI controller was successfully implemented in this study. The experimental results show that, the controller can maintain its voltage along with changes, both source and load voltage. Thus, it can be concluded that the Arduino Mega board can work well in closed loop applications for power converter control.

In an increasingly advanced era, electrical energy has become a basic resource for humans, the wider and more equitable distribution has greatly influenced the progress of all sectors of electricity users. However, on the other hand, this hydroponic business requires precision and special attention by the actors to support the maximum success of the hydroponic business. Several previous tools have been able to overcome the problem of irrigation for hydroponic plants. However, there is no tool that can regulate the addition of nutrients based on the internet of things and monitor the hydroponics. So, a tool for adding nutrients to hydroponic plants based on the internet of things was designed that is equipped with supervision on plant nutrition. It is hoped that after the manufacture and analysis of tools on hydroponic plants can overcome the problems that are often experienced by hydroponic entrepreneurs.The research was conducted from May to July 2022 in Margoutomo Dalam, Dau, Malang. This nutrient addition tool is designed using an Arduino Uno microcontroller where as a regulator and NodeMCU is added as an online access on the user's cellphone. After the tool has been designed, a regression analysis is carried out to determine the effect of nutrient levels on the fertility of hydroponic plants. The results of this study showed that the nutritional value of a good plant was 350 ppm, with the response rate of this nutrition enhancer at 1.62% per second at a distance of 338 km for testing the user.

DC-DC Converter is a direct voltage (DC) power supply device that is produced by converting DC input voltage into a lower or higher DC output voltage. In its development, the application of DC-DC Converter allows an electronic device to function with a small energy source, where the output voltage can be varied as needed. DC-DC Converters have been widely developed because they have various advantages, including: simpler form and has high efficiency. In this thesis, an Arduino Mega 2560-based current controller will be implemented. The type of current controller implemented is hysteresis current control with the well-known, tested and proven considerations. Current control works if the inductor current rises from the lower limit of the hysteresis band to the upper limit then the switch will be turned off (inductor current above the upper reference Ip.Ref) and if this current drops from the upper limit to the lower limit the switch will be turned on (current inductor under low frequency Iv.Ref). This current control also has advantages in overcurrent protection such as when there is a short circuit in the load.

Energy is one of the most important needs for humans to support daily life, especially for developing countries such as Indonesia. One of the energies needed in human life is electrical energy. For this reason, innovation was developed, namely a dry-type Single-Phase Transformer with a core geometry approach developed in the AL 1.01 building of the State Polytechnic of Malang. Calculations performed on the tool are to calculate the value of windings per volt (GPV) and the number of primary and secondary windings. Its manufacture uses a toroid-shaped transformer core. The core specification of the transformer is an outer diameter of 15cm, then an inner diameter of 5.8 cm, and a height of 7cm. The toroid transformer core that will be used is previously isolated from the transformer first to avoid leakage current which can cause heat in the transformer core. The density of the email wire from the transformer winding both from the primary and secondary windings will affect the performance of the transformer, the more tightly the email Wire is wrapped in the transformer core, the vibration generated from the transformer will be smaller, this will affect the voltage losses later in the transformer testing phase carried out using different beaban, each load changes the efficiency of the transformer that has been made will also change, this is because each load tested has different factors.

Indonesia is geographically located on the equator, which has very strong solar radiation and high rainfall, making it suitable for farming. Hydroponics is used as a growing medium for planting without using large areas of land by utilizing water and prioritizing the nutritional needs of plants. NFT is a hydroponic method that is easy to implement and is quite effective for plants. However, this method requires a cycle that cannot be stopped, so it requires a pump that must be on all the time. Therefore, a backup supply is needed that can guarantee the availability or continuity of the supply of electricity to the load by using an Automatic Transfer Switch (ATS) which keeps the system running if the PLN goes out by using PLTS and can be monitored and controlled at any time using Internet of things (IoT) technology. ). From the results of trials and analysis carried out that the performance of the system when in automatic mode, that is, when the battery reaches a value of 11.3 Volts, it will switch to the PLN supply. The supply from PLTS will change to PLN's supply automatically with a predetermined time, namely from 09.00 WIB to 15.00 WIB. If PLN experiences a blackout, it will switch to the PLTS source until PLN is back on.

This experiment discusses the effect of the variability of solar radiation due to partial shading and surface temperature of the PV Panel on the output power of 100 Wp solar panels. This study begins by determining the load of the system, i.e. DC pump in the nutrient circulation system of the DFT hydroponic system. From there, we can observe the change in solar panel power output and PV surface temperature change due to partial shade. This survey method actually measures the temperature and intensity of solar radiation and measures the power output of a solar panel, and the tools used are thermal sensors used to measure the surface temperature of solar panels. Solar power meter. to measure the solar irradiance and use the multimeter to measure the voltage and current, 10A capacity SCC battery, 100Wp capacity solar panel and 65Ah battery. The test will be conducted for 5 days, starting from 09:00 to 15:00 every day. This result shows that temperature increase affects the output power decrease when the solar panel is in normal condition (not half shaded condition). On the other hand, when partial shade conditions increase, the temperature does not affect the decrease in solar panel output power. The greater the intensity of partial shade produced by the solar panel, the lower the output power. However, for short periods of partial shade, the output power produced tends to be more stable than under normal conditions.
