Abstract

Pada tahun 2022, konsumsi energi PDAM Surya Sembada Kota Surabaya sebesar 91.893.660 kWh/tahun dengan biaya energi Rp. 409/m3. Mengacu pada Peraturan Menteri Energi dan Sumber Daya Mineral nomor 14 tahun 2012 tentang Manajemen Energi, pengguna energi yang menggunakan energi lebih besar atau sama dengan 6.000 ton minyak/tahun atau sekitar 70.000.000 kWh/tahun wajib melakukan manajemen energi. Salah satu langkah dalam manajemen energi adalah melaksanakan audit energi secara berkala. Audit energi ini bertujuan untuk mengevaluasi efisiensi pompa dan Konsumsi Energi Spesifik (KES) sehingga diketahui rekomendasi teknis yang tepat terhadap optimasi pompa yang saat ini beroperasi. Metode penelitian yang digunakan adalah metode deskriptif secara kuantitatif dan kualitatif dengan pendekatan studi kasus. Jenis audit yang diterapkan adalah audit energi awal. Dari hasil audit energi awal yang dilakukan, diketahui bahwa seluruh pompa memiliki nilai efisiensi pompa di atas 60% dan nilai KES kurang dari 0,4 kWh/m3. Hal tersebut mengindikasikan kondisi pompa eksisting masih sangat baik dan layak beroperasi. Nilai faktor daya (cos j) pada pompa 1 sebesar 0,813 sedangkan batasan minimun nilai faktor daya yaitu 0,85. Hal tersebut mengakibatkan PDAM akan terkena denda kVAr. Pemasangan kapasitor bank dapat menjadi solusi untuk menghindari denda kVAr yang diakibatkan nilai faktor daya kurang dari 0,85.

Abstract

The research aims to manage parking facilities so that there are no more vehicles parking in the area outside the Pakuan Jaya Market Perumda market; therefore, vehicles that park in the area outside the Pakuan Jaya Market Perumda market parking facility are placed in the Pakuan Jaya Market Perumda parking facility area so as not to reduce the road capacity. In this study, using the SRP method of characteristics (Volume, Accumulation, Duration, Turnover, Index), the performance management of paid parking is examined. Data collection was carried out by the survey method, with a time of 12 hours and running for sixteen days, with the data taken being the data of vehicle entry and exit hours to determine the characteristics of parking. The results of this study comprise the calculation of characteristics, including the maximum parking cumulation of 199 vehicles, which occurred on Friday, 12 April 2024 with a vehicle volume of 176 vehicles, and the maximum parking duration for At noon on the peak day, Thursday 4 April 2024, for sixteen days, the highest turnover of motorcycle parking at Perumda Pasar Pakuan Jaya Bogor City was observed at 30.03%. The maximum parking index reached 33.96%, indicating that the parking performance was relatively poor. However, the motorcycle parking capacity at Perumda Pasar Pakuan Jaya Kota Bogor was sufficient to meet the existing parking demand due to the capacity of the existing parking spaces. This was indicated by the parking index, which is less than 100%.
