Addition of the Guluk-Guluk Substation, it will affect the flow of power and voltage in the electric power system. Based on the analysis of normal conditions before and after the Guluk-Guluk Substation in terms of the voltage value on each connected bus, it is still within the permitted limits, while the contingency ranking calculation using the Voltage Performance Index (PIv) method can determine contingency conditions N-1 to N -3 before and after the Guluk-Guluk Substation. In this case, it was found that during the contingency conditions N-1 to N-3 before the Guluk-Guluk Substation there was a decrease in the value of the voltage which was still within the permissible limits, but in the N-3 contingency there was also an overload on the line due to the release of two generator units and one channel. After the existence of the Guluk-Guluk Substation, during the N-1 to N-2 contingency conditions the voltage value was still within the permissible limits, but the voltage drop that occurred was bigger than the condition before the Guluk-Guluk Substation. For the N-3 contingency condition the voltage value does not meet the standard due to overload on the Ujung Substation - Bangkalan Substation line and the lack of power flow.

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.

The Kalipare feeder is a feeder located at PT PLN (Persero) ULP Sumberpucung where the feeder has a feeder length of 232.9 kms and a load of 161.8 A, with a voltage drop of 17.981 kV, the energy loss that is not channeled in 40.82 minutes is IDR 5,333,734.00. So with that the feeder is carried out there is a splitting of the load into two, namely 86.6 A and 74.4 A, with the end voltage being 19.27 kV, with the energy loss that is not channeled in 40.82 minutes is Rp. 2,454.510.8. This load solving is carried out based on the existing conditions of the Kalipare Feeder in 2019, as well as modeling in the form of simulations using ETAP 12.6 and analyzing the simulation results with the existing load breaking conditions in 2020. Load splitting locations are carried out at 7 points taking into account the value of the investment to be made used to do the job. The locations where the load splitting will be carried out are GI Karangkates, Perempatan Peteng, Tumpakmiri, Kalipare, and Banduarjo with an investment cost of Rp. 21,124,247,696 with the construction of 527 gates. After breaking the load, which resulted in the Kalipare feeder and the Donomulyo feeder, the value of the voltage drop on the Kalipare feeder decreased to 18.25 kV; 8.70%, while the Donomulyo Feeder is 19.241 kV; 3.84%. The solution to the load of the Kalipare feeder will minimize losses due to blackouts and increase customer satisfaction.

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.
