Abstract
Potensi energi terbarukan di Indonesia mencapai 3.686 GW, namun pemanfaatannya baru sebesar 12,3% dari total konsumsi energi. Penelitian ini bertujuan untuk mengoptimalkan sistem Compressed Air-Gravity Energy Storage (CA-GES) yang lebih ramah lingkungan sebagai alternatif penyimpanan energi baterai berskala besar. Variabel yang dianalisis meliputi diameter piston, tinggi silinder, tinggi piston, massa jenis piston, volume bejana tekan, dan diameter pipa. Studi optimasi parametrik dilakukan dengan menggunakan model matematis yang diintegrasikan dengan Microsoft Excel dan Virtual Basic for Applications (VBA) untuk menghitung energi total sistem CA-GES. Metode Taguchi dan Analysis of Variance (ANOVA) digunakan untuk menganalisis signifikansi dan kontribusi parameter desain. Hasil penelitian menunjukkan bahwa diameter piston memberikan pengaruh paling signifikan terhadap energi total sistem dengan nilai P-value 0,009, diikuti oleh tinggi silinder dengan nilai P-value 0,036. Diameter piston memberikan kontribusi terbesar sebesar 52,35%, sedangkan tinggi silinder berkontribusi sebesar 24,49%, kemudian massa jenis piston memberikan kontribusi sebesar 2,5%. Sementara itu, tinggi piston dan volume bejana tekan memberikan kontribusi negatif masing-masing sebesar 6,38% dan 11,12%. Konfigurasi optimal untuk memaksimalkan energi total adalah diameter piston 0,3 m, tinggi silinder 3 m, tinggi piston 0,045 m, massa jenis piston 7850 kg/m³, dan volume bejana tekan 0,005 m³. Dengan demikian, penelitian ini dapat digunakan sebagai acuan awal dalam mendesain sistem CA-GES.*****The potential for renewable energy in Indonesia reaches 3,686 GW, yet its utilization is only 12.3% of total energy consumption. This study aims to optimize a more environmentally friendly Compressed Air-Gravity Energy Storage (CA-GES) system as an alternative to large-scale battery energy storage. The analyzed variables include piston diameter, cylinder height, piston height, piston density, pressure vessel volume, and pipe diameter. Parametric optimization was conducted using a mathematical model integrated with Microsoft Excel and Virtual Basic for Applications (VBA) to calculate the total energy of the CA-GES system. The Taguchi method and Analysis of Variance (ANOVA) were used to analyze the significance and contribution of the design parameters. The results show that the piston diameter has the most significant influence on the system's total energy with a P-value of 0.009, followed by the cylinder height with a P-value of 0.036. The piston diameter contributes the most at 52.35%, while the cylinder height contributes 24.49%, and the piston density contributes 2.5%. Meanwhile, the piston height and pressure vessel volume provide negative contributions of 6.38% and 11.12%, respectively. The optimal configuration to maximize total energy is a piston diameter of 0.3 m, cylinder height of 3 m, piston height of 0.045 m, piston density of 7850 kg/m³, and pressure vessel volume of 0.005 m³. Thus, this study can serve as an initial reference for designing a CA-GES system.
