Abstract

The stability of an airplane is influenced by aerodynamic characteristics, one of which is the lift coefficient (C). The value C is the ratio between the lift force (L) and the dynamic pressure (q). The value of C is determined based on the design of the airfoil shape and the use of the type of flap. The increase in C from the previous study using the simulation method obtained 20.4% with the addition of a flap. This study aims to simulate folds by adding vane (double slotted flap). The methodology in the study uses a simulation of Computational Fluid Dynamic (CFD). The research results of airfoils with the blade having a maximum C of 35.99% are higher than airfoil designs without vane, or 5.77 and 5.61 respectively. The maximum C value of an airfoil with vane or airfoil without using blade occurs at the angle of attack (α) = 16o. The research conclusion informs that vane influences the characteristics of the N2XX aircraft. Vane can minimize the occurrence of a stall (decrease in the value of C) of airplanes in take-off and landing conditions. Keywords: C, vane, double slotted flap, airfoil

Abstract

Pendidikan Islam di Indonesia memiliki akar sejarah yang kuat dan berkembang melalui berbagai institusi seperti pesantren, madrasah, dan sekolah berasrama. Penelitian ini membahas sejarah pertumbuhan dan perkembangan pendidikan Islam di ketiga lembaga tersebut, mulai dari masa awal hingga era modern. Pesantren sebagai institusi pendidikan tertua dalam tradisi Islam Nusantara memainkan peran penting dalam penyebaran nilai-nilai keagamaan dan pembentukan kader ulama. Seiring dengan kolonialisme dan modernisasi, muncul madrasah sebagai bentuk pendidikan formal yang mengintegrasikan kurikulum agama dan umum. Selanjutnya, sekolah berasrama muncul sebagai inovasi dalam menjawab tantangan pendidikan Islam kontemporer dengan menyediakan lingkungan pembelajaran yang terpadu. Studi ini juga menyoroti dinamika perubahan kurikulum, peran pemerintah, serta pengaruh globalisasi terhadap keberlanjutan dan transformasi lembaga-lembaga ini. Hasil penelitian menunjukkan bahwa ketiga institusi tersebut saling melengkapi dalam mempertahankan tradisi pendidikan Islam sekaligus beradaptasi dengan kebutuhan zaman

Abstract

This study examines the effects of digital marketing, electronic word of mouth (E-WOM), and product quality on purchase intention through perceived authenticity among Generation Z skincare consumers using TikTok in East Kalimantan. Using a quantitative survey, data was collected from 280 respondents and analyzed with SEM-PLS. The results indicate that digital marketing and product quality positively influence purchase intention and perceived authenticity. Perceived authenticity also significantly enhances purchase intention and mediates the effects of digital marketing and product quality. However, E-WOM has no significant direct or indirect effect. These findings highlight authenticity as a key driver of consumers’ purchase intention. Keywords: Digital Marketing; Electronic Word of Mouth; Product Quality; Perceived Authenticity; Purchase Intention; TikTok
