Abstract

B.IndonesiaSekolah Tinggi Penerbangan Indonesia memiliki sepuluh buah transformator yang tersebar pada tujuh buah gardu listrik. Setiap transformator memiliki kapasitas yang berbeda-beda. Besar nilai pembebanan yang ditanggung transformator dapat mempengaruhi kondisi transformator. Maka pada penelitian ini akan didapatkan seberapa besar nilai pembebanan transformator dengan melakukan pengambilan data yang berupa hasil pengukuran arus sisi sekunder pada transformator, nilai suhu transformator, dan nilai suhu gardu listrik. Setelah pengambilan data kemudian data diolah dengan mencari nilai rata-rata arus pada waktu beban puncak pada masing-masing transformator, selanjutnya menghitung nilai arus beban penuh pada masing-masing transformator dan yang terakhir menghitung nilai persentase pembebanan dari masing masing transformator. Dari hasil perhitungan nilai persentase pembebanan dilakukan analisis data. Dari hasil analisis data dapat disimpulkan bahwa transformator yang ada di Sekolah tinggi Penerbangan Indonesia masih memiliki nilai persentasi pembebanan dibawah 50% dengan beberapa gardu listrik yang memiliki suhu yang mendekati suhu maksimum karena tidak memiliki kipas pendingin dan ventilasi udara. B.EnglishIndonesia Civil Aviation Institute has ten transformers spread over seven electric substations. Each transformer has a different capacity. the value of the load borne by the transformer can affect the condition of the transformer. Then in this study will be obtained how much the value of the transformer loading by taking data in the form of measurements of the secondary side current on the transformer, the transformer temperature value, and the temperature value of the electrical substation. After taking the data then the data is processed by finding the average current value at the time of the peak load on each transformer, then calculating the full load current value for each transformer and finally calculating the percentage value of loading from each transformer. From the results of the calculation of the percentage loading value, data analysis is performed. From the results of data analysis it can be concluded that the transformer at the Indonesian Aviation High School still has a percentage value of loading below 50% with several electrical substations that have temperatures close to maximum temperatures because they do not have cooling fans and air vents.

Abstract

One of the important aspects of ensuring smooth operation, safety, and security in the terminal apron area is a lighting system that complies with applicable standards. However, substandard lighting conditions are still found at Husein Sastranegara Airport, as indicated by apron user complaints validated by the Assistant Electrical Manager, showing inadequate illumination levels that may affect safety and visual performance. Measurements showed that the average illumination level of the existing apron lighting system was 12.38 lux, which did not meet the standards specified in ICAO Annex 14 Volume 1 requiring 20 lux. This study aims to redesign the apron floodlight system to meet the applicable standards using the Research & Development method. The design was evaluated using DIALux evo software considering luminous flux, beam angle, mounting height, pole spacing, and lighting distribution. The simulation results showed that the proposed design successfully achieved the required illumination standard.
