Abstract

The energy industry faces major challenges in fuel inventory management due to price and demand fluctuations. PT Pertamina Hulu Kalimantan Timur (PHKT) faces this issue in the operation of Ship X, the crucial transportation between Balikpapan and Penajam Supply Base (PSB). Uncertainty in fuel demand can disrupt worker mobility and increase operational costs due to the high frequency of deliveries. Therefore, forecasting fuel consumption is important for efficiency and smooth operation. The purpose of this research is to forecast the amount of fuel that will be used by Ship X. The method used is a quantitative approach by utilizing secondary data on fuel consumption for the period January to September 2024 from PSB PHKT. In forecasting efforts, the Seasonal Autoregressive Integrated Moving Average (SARIMA) (1,1,0)(0,1,1)6 model is used. The selection of this model is based on parameter significance and fulfillment of the white noise residual assumption after going through diagnostic tests. The results of the study provide a prediction of the fuel usage of Ship X in week 40 of 1794.37 liters.

Abstract

CaO sebagai katalis heterogen telah berhasil dibuat dari cangkang keong mas (Pomacea canaliculata L) dengan metode kalsinasi suhu tinggi. Kalsinasi masing-masing dilakukan pada suhu 600°C, 700°C, dan 900°C selama 4 jam. Hasil difraksi sinar-X menunjukan Puncak karakteristik kalsium oksida (CaO) pada sudut 2θ = 32,16°; 37,15°; 64,16° dan 67,5°, yang dikonfirmasi sesuai dengan standard CaO (JCPDS No. 82-1690). Berdasarkan data TGA kalsinasi cangkang keong mas pada suhu 900°C selama 4 jam diketahui mampu mengkonfersi cangkang keong mas menjadi katalis CaO sebanyak 46,37% berat. Pada suhu kalsiniasi 600°C dan 700°C selama 4 jam, menghasilkan CaCO3 kalsit 11,1% berat, dan  CaCO3 vetiret 2,79% berat. Hasil SEM menunjukkan bahwa ukuran partikel serbuk padatan terkecil dimiliki oleh katalis CaO yaitu 13-1,2 µm dengan sebaran yang homogen. CaCO3 kalsit pada 600oC dan 700oC masing-masing memiliki ukuran antara 2,2 mm - 2,5 µm dan 1,6 mm - 1,25 µm dengan sebaran yang heterogen.
