Abstract

Permasalahan yang terjadi pada penyulang 20 kV adalah rendahnya tegangan pada sisi konsumen akhir yang melewati batas -10% terhadap tegangan nominal. Hal ini disebabkan oleh penggunaan konduktor AAAC dengan luas penampang 70 mm², panjang jaringan dan meningkatnya beban listrik konsumen. Solusinya adalah perlu dilakukan perbaikan drop voltage melalui uprating dan pembangunan penyulang 20 kV baru untuk pecah beban. Penelitian ini membahas tentang perbaikan drop voltage melalui uprating konduktor dan pembangunan penyulang 20 kV baru. Model ditetapkan sebagai sebuah jaringan sistem kelistrikan berupa single line diagram (SLD) 20 kV. Parameter yang ditetapkan: tegangan sistem, beban penyulang, panjang penyulang. ETAP 12.6.0 digunakan untuk simulasi perhitungan nilai drop voltage. Sebagai obyek penelitian ditentukan penyulang Camar GI 70/20 kV Binangga Kabupaten Parigi Moutong, Sulawesi Tengah yang mempunyai transformator kapasitas 10 MVA dan 30 MVA. Hasil menunjukkan bahwa ETAP 12.6.0 mampu digunakan untuk simulasi perbaikan drop voltage melalui uprating konduktor 70-240 mm² 68 kms dan pembangunan penyulang 20 kV 64,5 kms GI 70/20 kV. Hal ini dibuktikan dengan nilai tegangan ujung penyulang Camar yang semula 12,64 kV menjadi 18 kV. Kata kunci: Drop voltage, Uprating 70-240 mm², Pembangunan penyulang 20 kV, GI 70/20 kV.

Abstract

Magnetic Resonance Imaging (MRI) is a high-tech medical diagnostic equipment that plays an important role in healthcare, but in its operation it faces problems in the form of very large maintenance costs. This is due to the complexity of MRI technology, where the main unit of MRI is an imported product, while supporting equipment such as UPS, chiller, and AHU system are domestic products, thus impacting the increase in maintenance costs in hospitals and potentially reducing the quality of service. The solution to reduce maintenance costs, because maintenance cost efficiency can increase hospital profits. This study discusses the determination of maintenance priorities on MRI using a multi-criteria-based decision-making model by considering: the age of the MRI, the number of error logs, the condition of supporting equipment, and the expertise of the operator in operating the MRI. The Analytical Hierarchy Process (AHP) method is used with the stages of forming a decision hierarchy, pairwise comparisons, matrix normalization, priority weight calculation, and consistency testing. Data were obtained through questionnaires given to competent respondents, with the object of research at the Orthopedic Hospital, Surakarta, Indonesia. The results of the study indicate that the AHP method can be used to determine MRI maintenance priorities effectively. This is evidenced by the best alternative results, namely the Medium type (0.3372), followed by All Risk (0.3315), and Labor Only (0.3311). The Medium type is the most optimal choice. The AHP method has been proven to provide objective, structured, and accountable recommendations for hospital management in determining maintenance contracts that are appropriate to the technical condition of the equipment and budget constraints.
