BIAYA OPTIMASI KEBUTUHAN BAHAN BAKAR UNTUK MENGHASILKAN ENERGI LISTRIK

COST OPTIMATION OF FUEL CONSUMPTION TO PRODUCE

Author :
BUDI UTOMO ,SUKARNO 




ABSTRAK

Pembangkit Listrik Tenaga Uap PLTU untuk menghasilkan energi listrik melalui tahapan proses dari perubahan energi panas menjadi energi mekanik selanjutnya menjadi energi listrik dalam proses perubahan ini memerlukan bahan bakar minyak solar sebagai bahan bakunya. Pemakaian bahan bakar untuk menghasilkan energi listrik merupakan faktor yang sangat penting mengingat bahan bakar adalah bahan baku utama. Dengan mengetahui jumlah pemakaian bahan bakar serta berapa jumlah energi listrik yang dapat diproduksi maka nilai ekonomis dan keuntungan dapat dihitung. Optimasi biaya kebutuhan bahan bakar untuk menghasilkan energi listrik di Pembangkit Listrik Tenaga Uap PLTU dengan menggunakan metode Peramalan Linier Program Economic Order Quantity merupakan salah satu langkah menekan biaya produksi energi listrik. Optimasi biaya kebutuhan bahan bakar ini dapat meliputi masalah biaya penyediaan penyimpanan dan pemakaian dalam operasi mesinnya sehingga diharapkan nilai ekonomis dapat tercapai. Dalam pembuatan perencanaan optimasi biaya kebutuhan bahan bakar untuk menghasilkan energi listrik di PLTU periode satu tahun dengan penerapan hasil penentuan reorder point baru dibandingkan dengan reorder point lama terdapat penghematan rata-rata inventory dan biaya bahan bakar. Penghematan per hari tertinggi terjadi pada bulan ke-9 adalah sebesar 8769.07 K.lt dengan penghematan biaya inventory sebesar Rp 964.598.080- untuk penghematan inventory per hari terendah terjadi pada bulan ke-1 yaitu sebesar 4243.10 K.lt dengan penghematan biaya inventory sebesar Rp 466.741.006-.


ABSTRACT

To produce electricity the electricity raiser with steam power had to going through these steps start from changing the heat become mechanical energy. These processes require solar petrol. The of solar petrol is the main raw material knowing the amount of solar petrol used and mount of electricity product we can calculate the economical value and profitability.Solar petrol lost optimalization to produce electricity at the electricity raiser with steam power can be done by the forecasting methods liner programming and economic order quantity which can be an alternative to reduce the electricity producing cost. The solar petrol cost optimalization includes the cost of supply restore and cost of use in operation so the economical value can be reached. In the making of solar petrol cost optimalization plan to produce electricity at the electricity raiser with steam power for one year period with using the value of the new reorder point comparing with the old reorder point we can save the overage inventory and the cost of petrol. The highest cost saving per-day happened in the ninth month 87907 K.Lt. It with the inventory cost saving Rp 964598080. The lowest inventory cost saving per-day happened in the first month 424310 K.lt. With the inventory cost saving Rp 466.741.006.
