Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh rendahnya rasa percaya diri terhadap keaktifan dan disiplin belajar siswa di sekolah. Metode penelitian yang digunakan adalah kuantitatif dengan pendekatan survei korelasional. Pengumpulan data dilakukan melalui penyebaran angket menggunakan skala Likert kepada siswa sebagai responden. Data dianalisis menggunakan statistik deskriptif dan inferensial melalui uji regresi, uji-t, dan uji-F. Hasil penelitian menunjukkan bahwa tingkat rasa percaya diri, keaktifan, dan disiplin belajar siswa berada pada kategori sedang dengan persentase rata-rata sebesar 70%. Indikator tertinggi terdapat pada kepatuhan terhadap tata tertib sekolah sebesar 82%, sedangkan indikator terendah terdapat pada rasa percaya diri setelah melakukan kesalahan sebesar 58%. Hasil uji-t menunjukkan bahwa rasa percaya diri berpengaruh signifikan terhadap keaktifan dan disiplin belajar siswa. Siswa yang memiliki rasa percaya diri tinggi cenderung lebih aktif dalam pembelajaran dan lebih disiplin dalam menjalankan tanggung jawab belajar. Dengan demikian, rasa percaya diri memiliki peran penting dalam mendukung keberhasilan proses pembelajaran di sekolah.

Abstract

Advertising is one of the marketing strategies that plays an important role in influencing consumer behavior and increasing a company's competitiveness in the market. In monopolistic competition and oligopoly market structures, advertising activities are often used by companies to build brand image, create product differentiation, and attract consumer interest in the products offered. This study aims to analyze the influence of advertising in monopolistic competition and oligopoly markets in Indonesia. The research method used in this study is a literature review by examining various relevant scientific articles from reputable national journals published in recent years. Data collection techniques were carried out through the exploration of various literature sources related to advertising, consumer behavior, and market structure. The results of the study show that advertising has a significant influence on increasing brand awareness, shaping consumer perceptions, and encouraging purchasing decisions for a product. In addition, in monopolistic competition markets, advertising plays a role in creating product differentiation and increasing consumer loyalty, while in oligopoly markets advertising functions as a strategy to maintain the company's position and increase competitiveness among companies. Therefore, advertising activities are an important instrument in marketing strategies that can influence consumer behavior and strengthen a company's position in market competition.
