Analysis of Design Engineering Quality Inspection on Under Ground Cable Line (UGC) 150 kV Kebon Jeruk - Duri Kosambi

Inspection of Engineering Products is very important to improve the quality of products and services to customers, therefore it is necessary to pay attention to the cost, quality and time of engineering and ensure that the engineering products produced meet the standards, specifications and requirements determined by the Company. The construction work of the 150 kV UGC Kebon Jeruk - Durikosambi is to improve the electricity system of DKI Jakarta and rejuvenate the UGC 150 kV Kebon Jeruk - Durikosambi and improve the quality and reliability of electricity distribution to consumers. The methods in writing this scientific journal are Measurement and Data Collection, Analysis (simulation), Evaluation and Conclusion. The cable size used is N2XCAS2Y cable measuring 1600 sqmm and a KHA value of 1002A at a depth of 13 meters. Meanwhile, at a depth of 5 meters, a KHA value of 1069A was obtained. Overall, the duration of the construction work of the 150 kV Kebon Jeruk-Durikosambi UGC is 18 months with details that can be seen in Table 4. Based on the table, if the contract ends in 2025, this work will be completed at the end of June 2027. The estimated material and construction cost (EPC) for the construction plan of the 150 kV UGC Kebon Jeruk – Durikosambi which uses a type N2XCAS2Y conductor measuring 1600 mm2 with the Horizontal Directional Drilling (HDD) method along ± 9.5 km is Rp. 34 billion/kmr. The construction of the 150 kV UGC is in the construction stage, so it is hoped that the results of the Engineering Design Concept have met the quality standards that have been set.
