Motor induksi merupakan salah satu motor listrik yang luas penggunaannya. Dalam kondisi tertentu motor induksi tak jarang mengalami kerusakan yang disebabkan oleh beban berlebih, hubung singkat di dalam kumparan, maupun kondisi lingkungan yang membuat motor induksi bekerja diluar batas kemampuannya. Salah satu akibat dari kerusakan pada motor induksi adalah kondisi kumparan yang tidak memungkinkan untuk digunakan lagi sehingga harus dilakukan rewinding. Setiap tipe belitan stator motor induksi akan menghasilkan distribusi magnetomotive force (MMF) pada celah udara yang berbeda. MMF yang dihasilkan terdiri dari komponen fundamental dan komponen harmonisanya. Jumlah komponen harmonisa pada distribusi MMF celah udara menimbulkan torsi parasit yang akan berpengaruh pada unjuk kerja motor induksi. Pada penelitian ini akan dilakukan penelitian perbandingan bentuk distribusi MMF celah udara terhadap dua tipe belitan yang berbeda yakni terbagi-screw (Motor A) dan terpusat-terditribusi (Motor B) pada motor induksi 1 fasa dengan kapasitas 1 kW 1000 rpm. Dari analisis harmonisa dan berbeban Motor A memiliki komponen harmonisa lebih tinggi dibanding Motor B sehingga Motor B memiliki peforma yang baik dalam hal torsi sebesar 4,608 Nm dibanding Motor A sebesar 3,37 Nm.

Motor induksi merupakan motor listrik yang luas penggunaannya khususnya pada industri. Seringkali industri yang terletak jauh di pedalaman, bila terjadi kerusakan pada motor induksi dilakukan perbaikan dengan cara replacement antara motor induksi yang satu dengan motor induksi yang lain dan hanya diperhatikan daya motor dan sistem tegangan yang digunakan, sehinga seringkali dimensinya juga tidak persis sama. Dengan adanya kegiatan replacement tersebut diduga motor induksi tersebut akan mengalami banyak perubahan khususnya lebar celah udaranya. Untuk menghindari nilai effisiensi yang rendah, faktor daya yang buruk, dan kerapatan torsi yang rendah maka jarak celah udara suatu motor induksi tidak dirancang terlalu lebar. Di sisi lain distorsi distribusi kerapatan fluks celah udara dapat diminimalkan dengan memperbesar jarak celah udara. Penelitian ini dilakukan pengikisan sedikit diameter rotor pada motor induksi satu fasa rotor sangkar 1 kW 1000 rpm sehingga lebar celah udara 3,5 mm (Rotor A), 2,5 mm (Rotor B), dan 4 mm (Rotor C). Melalui analisis Finite Element menggunakan software FEMM 4.2 didapatkan kerapatan fluks celah udara tertinggi pada Rotor A 0,456 T, Rotor B 0,634 T, Rotor C sebesar 0,399 T. Sedangkan daya output saat beban nominal masing-masing motor didapatkan 0,77 kW (Rotor A), 1,03 kW (Rotor B), dan 0,69 kW Rotor C).

Energi surya memiliki kemampuan untuk menghasilkan listrik dengan biaya bahan bakar yang dapat diabaikan, tidak menyebabkan polusi dan tidak ada risiko adanya lonjakan harga bahan bakar. Penggunaan energi surya sebagai sumber energi listrik salah satunya adalah untuk penerangan jalan umum. Pemanfaatan panel surya sebagai smart street lighting di desa banjarejo dusun Ngamprong RT.02 RW.04 Kecamatan Pakis Kabupaten Malang didasari kondisi bahwa pemasangan lampu penerangan jalan masih bersifat individu masyarakat yang bersedia memberikan sambungan listrik untuk penerangan jalan. Selain itu sering kali dalam menyalakan dan memadamkan lampu penerangan jalan mengalami keterlambatan. Dari hasil analisis maka didapatkan penghematan energi listrik sebesar 21.6 kWh untuk model 1 dan 14.04 kWh untuk model 2 di setiap 30 harinya. Model 2 dalah model yang paling hemat, sehingga setting yang digunakan dalah setting model 2.

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 of the most important equipment components in the distribution of electrical energy is the distribution transformer.Distribution transformer if used continuously or continuously it can affect the performance of the transformer. The service life of thetransformer can be reduced more quickly if you do not pay attention to the factors that can make the transformer life shrinkage high. One ofthe causes of the reduced life of the transformer is due to loading. From the eleven transformers, it can be seen that there are differentloading variations, it is expected that the transformer life will remain at normal age. IEC 60354-1, 1991 stipulates the normal life of thetransformer is 20.55 years. The research method used is to perform calculations using the long-time method and 24-hour daily data bycalculating the loading at the time of LWBP and WBP on a 20 kV distribution transformer. Analysis of the calculation results revealed that thenormal condition of the transformer P1385 (68.66 %) winding temperature at LWBP 67.47°C and when WBP 69.45°C compared totransformer P0032 with overload conditions (120.91%) winding temperature when LWBP 60, 88°C and at WBP 119.51°C. From the data onthe lowest loading on the eleven transformers, namely transformer P0527 (41.69%) it is obtained that the estimated real aging age is 0.125and the estimated age of the P0527 transformer is >20 years. Compared to transformer P0032 (120.91%), the estimated real aging age is12,0003 p-u and the estimated age is less than 20 years or 9.5 years. Loading above 100% on the transformer based on the standard IEC60354-1, 1991 if it takes place continuously will cause heating of the transformer windings which can cause the shrinkage process in the lifeof the transformer to be faster.

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.
