Abstract

The reliability of the electric power distribution system is essential for life, economy, health and safety. This reliability can be assessed from several indicators, including SAIDI, SAIFI, and ENS which can describe the economic impact of blackouts. The results of the calculation in this study show that the SAIDI and SAIFI values for four Feeders at the Tanjung Api-api Substation are in a reliable state when viewed from the PLN Target that has been set, and are not reliable for Ferry Feeders, namely SAIDI at Ferry Feeders of 6.003570985 hours/year, Cargo Feeders of 0.272152778 hours/year, Pinisi Feeders of 0.771065263 hours/year and Roro Feeders of 1.477902547 hours/year. As for SAIFI on Ferry Feeders amounting to 3.230883689 times/customer/year, Cargo Feeders 0.16666667 times/customer/year, Pinisi Feeders 0.836271676 times/customer/year and Roro Feeders 1.67529189 times/customer/year. For the ENS value index on the four Feeders based on the calculation results, 396,201.8423 Kwh was obtained with a loss of Rp. 536,118,758.6 kWh, in the Ferry Feeder that was not distributed energy of 319,128.4392 kWh with a loss of Rp. 431,461,649.8, in the Cargo Feeder of 4,896.091948 kwh with a loss of Rp. 7,073,384,037, in the Feeder of 7,136.846081 kWh with a loss of Rp. 9,649,015,901 and in the Roro Feeder of 65,040.46513 kWh with a loss of Rp. 87,934,708.86.  The results show that the higher the unchanneled energy, the greater the losses experienced by PT. PLN (Persero).

Abstract

Perhitungan indeks keandalan sistem distribusi 20 kV pada Penyulang Hanoman dari rekapitulasi data PT. PLN (Persero) UP2D S2JB menggunakan metode Failure Mode and Effect Analysis (FMEA) dengan mengidentifikasi keandalan dengan nilai indeks SAIDI, SAIFI, CAIDI, ASAI dan ASUI dan dibandingkan dengan Standar PLN dengan nilai target tahun 2023 dan 2024 serta IEEE standard dengan nilai target tahun 2022 periode 1 tahun. Hasil perhitungan didapatkan nilai indeks SAIFI sebesar 1,020946144 gangguan/konsumen, nilai indeks SAIDI 0.947157819 jam/konsumen, nilai indeks CAIDI 0.927725546 jam/gangguan, nilai indeks ASAI 0,999879048 p.u. dan nilai indeks ASUI 0,000120952 p.u. Perbandingan dengan Standar PLN didapat nilai SAIFI dan SAIDI terkategori andal karena nilainya tidak lebih dari 1,8 kali/pelanggan/tahun untuk tahun 2023, tidak lebih dari 4,31 kali/pelanggan/tahun untuk tahun 2024, nilai SAIDI tidak melebihi dari 2,68 jam/pelanggan/tahun untuk tahun 2023, tidak lebih dari 6,43 jam/pelanggan/tahun untuk tahun 2024. Perbandingan dengan IEEE standard didapat indeks nilai SAIFI, SAIDI dan CAIDI juga terkategorikan handal karena SAIFI tidak lebih dari 1,10 interruptions/customer/year dan indeks SAIDI tidak lebih dari 2,09 hours/customer/year, untuk indeks nilai CAIDI tidak lebih dari 1,96 hours/interruption/year.
