Abstract

Bandar udara merupakan simpul transportasi strategis yang memerlukan dukungan infrastruktur energi listrik yang andal dan berkelanjutan. Di Indonesia terdapat 367 bandar udara aktif, salah satunya Bandar Udara Jenderal Besar Soedirman Purbalingga yang masih berada pada tahap pengembangan fasilitas. Kondisi bangunan yang belum sepenuhnya permanen menuntut perencanaan kebutuhan energi listrik secara komprehensif guna mendukung peningkatan pelayanan. Penelitian ini bertujuan memproyeksikan kebutuhan energi listrik kawasan pengembangan bandar udara melalui simulasi menggunakan perangkat lunak Rhinoceros dan Urban Modeling Interfaces. Hasil simulasi menunjukkan nilai Floor Area Ratio sebesar 0,02 dengan rata-rata konsumsi energi operasional 173 kWh/m²/tahun, yang masih memenuhi standar keberlanjutan ASEAN-USAID. Total kebutuhan energi listrik mencapai 4.323.719,87 kWh/tahun, dengan beban terbesar berasal dari sistem pendingin sebesar 47,82%. Analisis pencahayaan alami, emisi karbon, dan mobilitas menunjukkan bahwa kawasan pengembangan masih berada dalam batas aman dan berkelanjutan.

Abstract

This study presents the design, simulation, fabrication, and experimental validation of a Savonius Helix vertical axis wind turbine optimized for low wind regimes in Cilacap, Indonesia. Wind data from NASA POWER were analyzed at two locations, revealing dominant low wind conditions with notable temporal variability. The turbine geometry was optimized based on aerodynamic and inertial parameters, followed by Computational Fluid Dynamics (CFD) simulations to evaluate torque, pressure distribution, and power coefficient across four configurations (2B90P, 2B180P, 3B90P, 3B180P). The optimal design was fabricated using fiberglass and tested under no-load and loaded conditions with a Permanent Magnet DC generator. Results indicate strong agreement between CFD trends and experimental performance, despite deviations caused by mechanical losses and atmospheric turbulence. Overall, the Savonius Helix configuration demonstrates effective energy capture capability in low wind environments, confirming its feasibility for small-scale renewable energy applications.
